This invasive pest has also been discovered in Pennsylvania and other states, and is a potential threat to important agricultural crops, including grapes, apples, hops and forest products.
According to the Canadian Food Inspection Agency (CFIA), the pest is not known to occur in Canada and is not yet on Canada's list of regulated pests. However, it may appear in Canada. Any producers who believe they have found suspect specimens are urged to please contact the CFIA.
Tim Weigle, statewide grape and hops integrated pest management specialist with the New York State Integrated Pest Management Program, works with grape and hop growers in implementing research-based IPM practices in environmentally and economically sustainable ways. He says the spotted lanternfly could rapidly expand its range by laying eggs on motor vehicles.
“The name spotted lanternfly is a bit misleading as this plant hopper grows to one-inch in size as an adult,” he said. “Large groups of both the immature and adult stages of laternfly feed on plant stems and leaves from early spring to September, weakening and possibly killing the plant. They also excrete a sugary, sticky substance similar to honeydew, which leads to the growth of sooty mold on grapes, apples and hops making them unmarketable.
“I would be concerned about any shipments that people are getting that originated in the Pennsylvania counties that are currently under quarantine. While this pest seems to prefer tree of heaven, it appears to be able to lay its eggs on any smooth surface like cars, trucks, tractors or stone. Therefore, the major traffic corridors coming up into the Hudson Valley and Finger Lakes area will probably have a greater potential for spotted lanternfly eggs being transported in due to vehicle traffic.”
Elizabeth Lamb, coordinator for the ornamental integrated pest management team for the New York State Integrated Pest Management Program says that grape, hop and ornamental growers, along with tree-fruit producers, are most likely to be impacted by this invasive pest.
“The industries most likely to be affected by spotted lanternfly in New York state are grapes and hops, tree-fruit production, and ornamentals,” she said. “Once you consider the ornamental hosts, it becomes an issue for homeowners and landscapers, too. So the first and most important piece in controlling spotted lantern fly is observation and monitoring – by growers and the public.
“A small bright spot: the biology of the insect provides several avenues for using different methods of control. Egg masses can be scraped off the smooth surfaces where they are laid and then destroyed. Nymphs crawl up and down tree trunks to feed so they can be caught on sticky traps at the right time. Adults have a preference or requirement for feeding on Ailanthus trees (Tree of Heaven), so the Ailanthus can be used as ‘trap’ trees where pesticides are applied very specifically to control the insect without widespread use.”
Broccoli has been grown in Europe for centuries, but it has only been grown in North America since the late 1800s, when it was probably introduced by Italian immigrants. Although California is the major producing state, broccoli is grown in nearly every other state, especially along the eastern seaboard.
The likelihood of high-temperature stress occurring in a given location or season is the main factor limiting where and when the crop can be grown. Breeding heat-tolerant broccoli cultivars could extend the growing season, expand production areas, and increase resilience to fluctuating temperatures, but efforts to do this have been limited by a lack of knowledge about the genetics of heat tolerance.
Agricultural Research Service (ARS) plant geneticist Mark Farnham and his team at the U.S. Vegetable Laboratory in Charleston, South Carolina, are filling in those knowledge gaps. They have developed and characterized genetic sources of heat tolerance in broccoli. These results were published in Theoretical and Applied Genetics in March 2017.
The team evaluated a group of broccoli plants that Farnham developed for the ability to tolerate high-temperature stress during summer.
“We identified genetic markers associated with resistance to heat damage in these plants,” says Farnham. “An important finding of this work is that the resistance trait is a complex trait controlled by many genes, which makes it a bit harder to work with. However, these markers are of great interest to public and private broccoli breeders, who can use some additional tools in their work to accelerate the development of heat-tolerant broccoli cultivars.”
To determine how well Farnham’s heat-tolerant broccoli will do in different stress environments, he is working with scientists at land-grant universities on the eastern seaboard that are growing his broccoli in warm-temperature field trials. Once they verify that his broccoli will do well under adverse conditions in different locations, it will be made available for research purposes or for use by commercial seed companies and breeders.
The heat-tolerant broccoli could help expand future growing possibilities significantly, helping to meet the demand for the nutritious vegetable.

With NAFTA renegotiation talks in full swing, it is a critical time for a conversation on protecting and improving our shared food supply chain. As think tanks and think networks, CAPI and the Wilson Center know the importance of good debate and a robust marketplace for ideas. This short piece, written by Rory McAlpine and Mike Robach, encourages just such debate.
"The contents of the piece represent an opportunity for our two organizations to present to our respective stakeholders on the frontlines of Canada-US economic policy some new thinking on important food safety issues", said Don Buckingham, president and CEO of CAPI. "Food safety is not just about consumer protection, it's about enhancing the competitiveness of the Canada-U.S. agri-food supply chain around the world. A well-functioning food safety regime helps to increase global demand for safe and wholesome North American food products."
"During a period of trade upheaval and fractured supply chains, it is particularly important to bring practical suggestions to the table that will build trade, increase competitiveness and safeguard the protection of consumers," added Laura Dawson, director of the Canada Institute of the Wilson Center.
The short piece is available here.
The project – VitisGen2 – is a collaboration of 25 scientists from 11 institutions who are working in multidisciplinary teams to accelerate development of the next generation of grapes. Launched in 2011, the project was recently renewed with a $6.5 million grant from the U.S. Department of Agriculture’s National Institute of Food and Agriculture, Specialty Crop Research Initiative.
The work has the potential to save millions of dollars annually for the U.S. grape industry – in excess of $100 million in California alone, according to Bruce Reisch, professor of grapevine breeding and genetics in the College of Agriculture and Life Sciences (CALS), who co-leads the project with Lance Cadle-Davidson, plant pathologist with the USDA-ARS Grape Genetics Research Unit, both located at Cornell’s New York State Agricultural Experiment Station in Geneva, New York.
VitisGen2’s multipronged model addresses the grape production continuum. An economics team examines the benefits of improving grape varieties. Geneticists identify molecular markers for important traits in grapes, from resistance to diseases like powdery mildew to boosting low-temperature tolerance and fruit quality. Grape-breeding scientists develop new grape varieties that incorporate these traits, and teams of outreach specialists help growers and consumers understand the advantages of newly introduced grape varieties.
The result is a new generation of high-quality grapes that can be grown at lower cost and adapt easily to a range of geographic regions and climates, all with less environmental impact.
“We all stand to benefit in areas ranging from the environment to economic sustainability to improving the profit and quality possibilities for the industry,” Reisch said.
Among the achievements in the project’s first five-year phase:
- Deploying DNA sequencing technology to map the grape genome, a project led by Cadle-Davidson and Qi Sun of the Cornell Bioinformatics Facility.
- Identifying 75 genetic markers associated with a range of important traits.
- Pinpointing a gene that controls acidity in grapes. The discovery by the winemaking fruit quality team, led by Gavin Sacks, associate professor of food science in CALS, will help winemakers moderate excessive acid levels typically found in wild grape species, which are often used in crossbreeding for their resistance to disease.
- Developing a process called Amplicon Sequencing, or AmpSeq, that allows researchers to rapidly analyze genetic variation in multiple genomic regions – anywhere from 2 to 500 DNA sequence markers – simultaneously.
Looking to the future, Reisch and the VitisGen2 teams are aiming to expand the use of high-throughput DNA and plant evaluation technology to improve the quality of wine, raisin and table grapes, as well as rootstocks. VitisGen2 is using genome sequencing to identify markers within numerous genes of interest to better understand which genes are controlling priority traits.
The team is also looking at ways to use its collective knowledge of genetics to help growers manage vineyards. For example, AmpSeq technology can track the powdery mildew pathogen population, allowing researchers to determine which pesticides are most effective at specific times of the season, thereby reducing pesticide spraying and increasing its efficacy.
Ultimately, VitisGen2 will bring greater efficiency to grape growing, which is an intensive, comprehensive and costly process, said Reisch.
“It takes 15-plus years to get a new variety to the market,” Reisch said. “We’re probably shrinking the timeline down by two or three years.”

The collaborative grant is good news for strawberry farmers and consumers everywhere, according to Rick Tomlinson, president of the California Strawberry Commission. To signal its own support, the strawberry commission pledged an additional $1.8 million to the UC Davis program.
“An investment in the UC Davis strawberry breeding program is an investment in the future of strawberries,” Tomlinson said. “Thanks to their groundbreaking research and strong partnerships, Director Steve Knapp and his colleagues are developing improved strawberry varieties publicly available to farmers.”
Improving genetic resistance to disease
Strawberries constitute a $4.4 billion-dollar industry in the United States, and 94 percent of the nation’s strawberry fruit and nursery plants are grown in California and Florida.
Strawberries are especially vulnerable to soil-borne pathogens, which destroy plants and greatly reduce yield. Since the 1960s, strawberry growers have depended on fumigants like methyl bromide to treat soils before planting berries in an effort to control disease. But methyl bromide has been phased out by the Environmental Protection Agency and will no longer be available after 2017.
“Following the elimination of methyl bromide fumigation, strawberry growers are under greater economic pressures, and there is an urgent need for improved, disease-resistant strawberry varieties that will thrive without fumigation,” Knapp said.
Knapp will head a team of scientists from UC Davis, UC Santa Cruz, UC Riverside, the UC Division of Agriculture and Natural Resources, Cal Poly San Luis Obispo, and the University of Florida.
Together, researchers will identify and manage pathogen threats, mine elite and wild genetic resources to find natural sources of resistance to pathogens, and accelerate the development of public varieties resistant to a broad spectrum of disease and other pests.
“Strawberry growers are faced with the need to deliver high-quality fruit to consumers year-round, while protecting the environment, fostering economic growth in their communities and coping with profound changes in production practices,” Knapp said. “We look forward to collaborating with our industry partners through research, agricultural extension and education to help them reach those goals.”
UC Davis Public Strawberry Breeding Program
During six decades, the UC Davis Public Strawberry Breeding Program has developed more than 30 patented varieties, made strawberries a year-round crop in California and boosted strawberry yield from just 6 tons per acre in the 1950s to 30 tons per acre today.
Knapp took over directorship of the program in 2015. He and his team are working to develop short-day and day-neutral strawberry varieties; studying the genetics of disease-resistance, fruit quality and photoperiod response; and applying genomic techniques to make traditional strawberry breeding more efficient. They have 10 public varieties in the pipeline and plan to release one or two new strawberry varieties later this year.
The grant is funded by USDA’s Specialty Crop Research Initiative. Collaborators from UC Davis include agricultural economist Rachael Goodhue, plant pathologist Thomas Gordon, and plant scientists Julia Harshman and Thomas Poorten.
Other key collaborators are Oleg Daugovish with UC Agricultural and Natural Resources; Alexander Putman at UC Riverside; Julie Guthman at UC Santa Cruz; Gerald Holmes and Kelly Ivors, both at Cal Poly; and Seonghee Lee, Natália Peres and Vance Whitaker, all of the University of Florida.
"It’s true that some technologies don’t exist yet, but the compact, planar architectures with precision canopy management are most suitable for future mechanization and even for robotics," said Matthew Whiting, Washington State University research horticulturist. “So it is kind of an exciting time for what will be a new era of tree fruit production, as more and more technologies become available."
Research labs and research orchards are driving new developments, but in many cases, they’re happening with innovative growers and private companies, he said.
“Growers are innovating with orchard systems and varieties and architectures, and that’s fueling university research in many cases, and conversely, universities are driving new genotypes and how to manage and grow them best,” Whiting said. “It’s all coming together as it has never before, and it is an exciting time.”
At the same time, employing the mechanization tools that already exist can take a variety of forms, across all four seasons.
Those platforms you’re using for harvest? You can use them for pruning, green thinning and training, too.
Two growers whose companies have been pushing forward with platforms, hedgers and other tools shared their insights for automating tasks in winter, spring, summer and fall with Good Fruit Grower.
For Rod Farrow, who farms 520 acres of apples at Lamont Fruit Farm in Waterport, New York, the emphasis has been to increase income with high-value varieties and to reach maximum potential income on his standard varieties, Honeycrisp, Fuji and Gala.
Almost everything is planted on Budagovsky 9 rootstock in 11-foot by 2-foot spacing, and he’s been planting and pruning to a fruiting wall for almost 18 years.
“It’s less about employing mechanization by season than about deciding the orchard system — as much as anything, making sure the system that you plant now is suitable for robot use,” he said. “If it’s not, you’re going to be in trouble in terms of how you can adapt that new technology, which is coming really fast.”
In the past two years, Farrow also has elected to install 3-foot taller posts in new plantings, allowing for a 2-foot taller system intended to increase production from 60 to 70 bins per acre to a more predictable 80-bin range. READ MORE

Participants included primary producers, processors, retailers, policy makers and academics – all putting their heads together to come up with new solutions to what is becoming a persistent problem; how do you attract and retain farm workers?
Marc Smith, retired assistant director of the New York State Agricultural Experiment Station in Geneva, NY, and senior Extension associate, opened the discussion with an international perspective on shared agricultural labour challenges among the United States and Canada.
Smith started off by identifying several trends in the U.S. agricultural labour climate:
- Regardless of government policy, people seeking employment in agriculture will be scarce.
- Economic and other motivations to develop and adopt labour-saving technologies are growing.
- Political and economic pressures will force minimal wages higher in many states.
- Perception of agriculture as an unattractive field for careers is a perennial challenge.
In Canada, the gap between labour demand and the domestic workforce in agriculture has doubled from 30,000 to 59,000 in the past 10 years and projections indicate that by 2025, the Canadian agri-workforce could be short workers for 114,000 jobs. This was a key finding of Labour Market Information (LMI) research by CAHRC entitled Agriculture 2025: How the Sector’s Labour Challenges Will Shape its Future. The LMI research also revealed that Canadian primary agriculture had the highest industry job vacancy rate at seven per cent – higher than any other industry in Canada. This resulted in $1.5-billion in lost sales.
Poor worker compensation is often cited as the primary reason for low interest in working on farms. However, Smith notes that agricultural wages in the U.S. have gone up faster than any other sector in the past 10 years with the median wage being $13.23/hr ($17.76 CDN) as of April 2017. In Canada, farm hourly rates averaged $17.50/hr in 2016.
Smith advocates that wages alone are not the issue but rather what is needed is a coordinated effort to improve labour policy, on-farm workforce needs, and farm practices.
Smith suggests that farmers need to develop realistic policies that attract and retain workers. Investment in leadership and management capacity within the agricultural industry is also needed to encourage innovation, research and development for long-term solutions to the already critical agricultural workforce.
It is not enough to simply pay required wages and comply with regulations. Employee compensation should also include how workers are treated and have their needs accommodated such as providing housing, access to the internet, transportation, communications in their own language, offering English as a second language training, job training, flexible hours, and creating a sense of community. It is important to make workers feel welcomed, valued and confident.
Finally, modifying farm practices to reduce the need for labour is another way to reduce on-farm workforce pressures. This may include adopting new technology that negates the need for human workers, changing crop mixes to less labour intensive commodities, or moving production operations to streamline efficiency.
To help attract and retain a motivated workforce, CAHRC has developed several tools to help farm managers including: AgriSkills – customizable and commodity specific on-farm training programs; Agri HR Toolkit – an online resource guide and templates to address the HR needs of any business; and Agri Pathways – promoting careers in agriculture. For more information on these and other CAHRC offerings visit www.cahrc-ccrha.ca.
In the meantime, Smith says producers should champion farmers that are doing a great job with their workers and get the word out that agriculture is a rewarding and fulfilling career with a strong future.
July 28, 2017, North Carolina - Laura Lengnick is a big thinker on agriculture and the environment. She has been guided in her work by the understanding that the problems generated by the U.S. industrial food system have been as significant as its ability to produce vast quantities of food. As she sees it, it’s not enough to produce food if there’s not a reckoning of costs and benefits from an unbalanced system.
This comprehensive outlook is a hallmark of Lengnick’s work, as is her positive vision for a more equitable and sustainable future. When it comes to her career, the question is not what work Lengnick has done to explore resilient, sustainable agriculture, but what hasn’t she done. Soil scientist, policymaker as a Senate staffer, USDA researcher, professor, sustainability consultant, advocate—Lengnick has done it all.
With her home nestled in a sunny cove in the North Carolina mountains, she bio-intensively tends to her 3,000-square-foot micro-farm. (She grows everything from greens and radishes to figs and sweet potatoes.) Based on her rich experience and deep expertise, Lengnick now views herself as a science interpreter in her interactions with farmers, public officials and the public at large. (She calls it “science-in-place").
Lengnick is the author of many articles and papers for scholars, practitioners and the general public, including the useful and engaging book Resilient Agriculture: Cultivating Food Systems for a Changing Climate. She was also selected as a contributor to the Third National Climate Assessment, the authoritative U.S. climate report.
Over the years she’s traveled throughout the United States to meet with farmers to investigate the challenges and successes in the field and present her findings to many different audiences. Most recently, Lengnick has been invited to collaborate with the world-renowned Stockholm Resilience Centre, which will bring her views to an even larger audience. In a series of conversations, Lengnick and I spoke about her background, career, and philosophy to better explain where she is today. READ MORE
Every day, handlers and applicators transfer potentially hazardous chemicals and concentrates such as pesticides, herbicides, insecticides, fungicides, and liquid fertilizers from large drums into smaller containers or mixing tanks. This transfer process can have serious consequences if manual “tip-and-pour” techniques or poorly designed pumps are used.
Whether the chemicals are toxic, corrosive, or flammable, the danger of accidental contact can pose a severe hazard to workers.
In fact, each year 1,800 to 3,000 preventable occupational incidents involving pesticide exposure are reported in the U.S. A closed system of transferring chemicals reduces unnecessary exposures by providing controlled delivery of chemical products without fear of worker exposure, over-pouring, spilling, or releasing vapours.
“When handling pesticides, toxicity and corrosiveness are the main dangers, but even organic pesticides can be harmful if there is exposure,” says Kerry Richards, Ph.D., president elect of the American Association of Pesticide Safety Educators and former director of Penn State’s Pesticide Safety Education Program. “No matter what their toxicity level, all chemicals, even those that are organic are a particular contact exposure risk if they are corrosive.”
In addition to the potential for injury, there can also be serious financial ramifications for the grower or ag product manufacturing facility if pesticides or liquid chemicals spill.
“Beyond workers compensation issues related to exposure, there can be other huge potential liabilities,” Richards says. “This is particularly true if a pesticide gets into a water source, kills fish, or contaminates drinking water.”
Richards, who works with the National Pesticide Safety Education Center, has seen and heard many examples of worker and environmental exposure from pesticides during more than 30 years of pesticide safety education experience.
“Exposure risk is highest for those loading chemicals into mix tanks because it is more concentrated and hazardous before diluted with water,” she says. “Any time you lose containment of the chemical, such as a spill, the risks can be serious and spiral out of control.”
Corrosive chemicals, for example, can severely burn skin or eyes, and many chemical pesticides are toxic when touched or inhaled.
“Some organic herbicides are so highly acidic that they essentially burn the waxy cuticle off the above ground parts of plants, killing them,” says Richards. “If you splash it in your eye or on your skin, it can burn in the same way and cause significant damage.”
Some chemicals are flammable as well, and if not properly handled and contained, can be ignited by sparking from nearby motors or mechanical equipment. The danger of a fire spreading can be serious both in the field and at ag product manufacturing facilities.
In addition to the cost of cleanup or treating injuries, substantial indirect costs can also be incurred. These include supervisors’ time to document the incident and respond to any added government inspection or scrutiny, as well as the potential for slowed grower production or even a temporary shutdown at ag manufacturing plants.
“The direct and indirect costs of a pesticide spill or injury can be substantial, not the least of which is the loss of wasted chemicals,” says Richards. “Pesticides, particularly newer concentrated formulations, are very expensive so spilling a few ounces could cost you several hundred dollars in lost product during a single transfer.”
Traditional practices of transferring liquid chemicals suffer from a number of drawbacks.
Manual techniques, such as the tip-and-pour method, are still common today. Tipping heavy barrels or even 2.5-gallon containers, however, can lead to a loss of control and over pouring.
“When manually transferring chemicals from bulk containers, it is very difficult to control heavy drums,” cautions Richards. “I’d advise against it because of the significantly increased risk of exposure or a spill, and the added potential of a back injury or muscle strain.”
Although a number of pump types exist for chemical transfer (rotary, siphon, lever-action, piston and electric), most are not engineered as a sealed, contained system. In addition, these pumps can have seals that leak, are known to wear out quickly, and can be difficult to operate, making precise volume control and dispensing difficult.
In contrast, closed systems can dramatically improve the safety and efficiency of chemical transfer. California’s Department of Pesticide Regulation, in fact, requires a closed system for mixing and loading for certain pesticides so handlers are not directly exposed to the pesticide.
“The availability of new technology that creates a closed or sealed system is ideal for handling pesticides or other dangerous chemicals, and should become a best management practice,” suggests Richards. “With such devices ... pesticide handlers can maintain a controlled containment from one vessel to another and significantly reduce any potential for exposure or spill.”
A sealed system delivers liquids to an intermediate measuring device and is useful for low toxicity liquids. A closed system moves the material from point A to point B through hoses using dry-break fittings on the connection points. This prevents leaking and exposure to the handler which helps guarantee safety. Liquids are transferred from the source container, into the measuring system, and then to the mix tank.
Small, versatile, hand-operated pressure pumps are engineered to work as a system, which can be either closed or sealed. The pumps can be used for the safe transfer of more than 1,400 industrial chemicals, including the most aggressive pesticides.
These pumps function essentially like a beer tap. The operator attaches the pump, presses the plunger several times to build up a low amount of internal pressure, and then dispenses the liquid. The device is configured to provide precise control over the fluid delivery, from slow (1ML/ 1 oz.) up to 4.5-gallons per minute, depending on viscosity.
Because such pumps use very low pressure (<6 PSI) to transfer fluids through the line and contain automatic pressure relief valves, they are safe to use with virtually any container from 2-gallon jugs to 55-gallon drums.
When Jon DiPiero managed Ricci Vineyards, a small wine grape vineyard in Sonoma, Calif., he sought a safer, more efficient way to transfer pesticides for mixing and spraying that complied with the state’s closed system requirement for certain pesticides.
“We had to fill 2.5-gallon containers from a 55-gallon drum,” says DiPiero. “Traditional tipping and pouring from a drum wasn’t going to work due to the potential for spills, splashes, over pouring and chemical exposure, as well as the state mandate for a closed system for some pesticides.”
DiPiero turned to GoatThroat Pumps and was happy with the results for a number of reasons.
“Because the pump is closed, sealed, and allows containers to remain in an upright position, it complied with state regulation and virtually eliminated the potential for all forms of chemical exposure,” DiPiero says.
He adds the air pressure supplied by the hand pump allows the precise flow required into a measuring cylinder.
In case of overfill, “the operator can open a valve to release air pressure and the pesticide will backflow into the tank with no cross contamination,” DiPiero says. “This gave us the exact amount we needed so there was no waste.”
According to DiPiero, a multi-directional spray attachment also enables rinsing of every corner of the container without having to pour into it and shake it. He says this helps to minimize exposure when cleaning a container for reuse and satisfies California “triple rinsing” requirements.
“Whether for pesticides, herbicides, fungicides, or liquid fertilizers, a closed and sealed pump design could help with the safe production or mixing of any liquid chemical,” says DiPiero.
When Lancaster Farms, a wholesale container plant nursery serving the Mid-Atlantic and New England regions, required a lower pH to adjust its well water for a pesticide spray application, it had to transfer sulfuric acid to buffer the spray water.
According to Shawn Jones, Lancaster Farms’ propagation and research manager, the nursery chose to purchase 55-gallon drums of sulfuric acid to raise chemical pH. The drums of chemicals were much more cost effective than multiple 2.5-gallon containers and much easier to recycle. However, Jones was wary of the danger that tipping and pouring acid from the drums would pose, along with pouring bleach and another strong disinfectants for different uses in the propagation area.
“We use 40 percent sulfuric acid to buffer our spray water,” Jones says. “Our irrigation water is all recycled from ponds, with the drum storage areas relatively close to our water source, so we wanted to avoid any possibility of accidental spillage.”
Previously, the nursery had used siphon pumps to transfer the acid, bleach, and disinfectant, but Jones was dissatisfied with this approach.
“None of our siphon pumps lasted more than six months before we had to replace them, and none allowed metering with the kind of precision we required,” he says.
Instead, Jones chose to implement several closed, sealed GoatThroat Pumps, along with graduated cylinders for precise measurement.
“With the pumps, the drums always remain in an upright position so they won’t tip over accidentally,” Jones says.
The one-touch flow control dispenses liquids at a controlled rate.
“We get precise measurement into our mix tanks. We use every drop, spill nothing, and waste nothing.”
In terms of longevity, Jones’ first sealed pump has already lasted six years and outlasted a dozen previous siphon pumps.
“Our GoatThroat Pumps paid for themselves in safety and savings our first growing season, and should last a decade or more with just routine maintenance or repair,” Jones concludes. “Any grower, farmer, or nursery that needs to move or measure dangerous liquids safely and reliably should consider one.”
Agricultural chemicals are very expensive, and growers are always looking for ways to decrease the cost of inputs to help increase profits. Sealed systems and closed systems allow for accurate and precise measuring of chemicals, which ensures that you’re using only the amount of product required and not one extra drop.
Taking the guesswork out of measuring costly materials, and providing an efficient means of transferring custom blended or dilute products from original containers to mix tanks or back pack sprayers cuts input costs. This keeps expenses to a minimum, with the important bonus of increasing the safety of handlers by reducing the potential exposure to the chemical, which helps increase the bottom line and can assist with regulatory compliance.
The re-evaluation led to some changes and restrictions on the product label. This included eliminating its use in residential areas plus as an insecticide on some fruit and vegetable crops.
Apple thinning has remained on the label but at reduced rates:
- Maximum seasonal rate of 1.5 kg a.i./ha and an REI of 14 days for hand thinning [high-density trellis production such as spindle or super spindle]
- Maximum seasonal rate of 1.0 kg a.i./ha and an REI of 17 days for hand thinning [dwarf, semi-dwarf and full-sized trees]
Researchers from Cornell Cooperative, CCE Lake Ontario Fruit Program educator and the Lamont Fruit farm conducted a three-year mechanical thinning trial. Watch above for more!
Consumers increasingly savour the convenience and taste of seedless watermelons, said Xin Zhao, a UF Institute of Food and Agricultural Sciences associate professor of horticultural sciences and lead author of a new study examining rootstocks, flavour and texture of watermelons.
Many growers produce seedless cultivars because that’s what consumers want, and it’s important to maintain the fruit’s yield and taste, as seedless cultivars might be more susceptible to fusarium wilt, a major soil-borne disease issue in watermelon production, Zhao said.
For the study, UF/IFAS researchers grafted seedless watermelon onto squash rootstocks to ward off soil-borne diseases, such as fusarium wilt. In plant grafting, scientists call the upper part of the plant the scion, while the lower part is the rootstock. In the case of vegetable grafting, a grafted plant comes from joining a vigorous rootstock plant – often with resistance or tolerance to certain soil-borne pathogens – with a scion plant with desirable aboveground traits.
Grafting is a useful tool to manage soil-borne diseases, but in this study, researchers were concerned that if they grafted watermelon onto squash rootstocks, they might reduce its fruit quality and taste. Overall, study results showed no loss in taste and major fruit quality attributes, like total soluble solids and lycopene content, Zhao said. Consumers in UF taste panels confirmed the flavour remained largely consistent between grafted and non-grafted plant treatments under different production conditions.
Furthermore, said Zhao, compared with the non-grafted seedless watermelons, plants grafted onto the squash rootstocks exhibited a consistently higher level of flesh firmness.
“We are continuing our grafted watermelon research to optimize management of grafted watermelon production, maximize its full potential and seek answers to economic feasibility,” she said.
Still to come is a paper that specifically tells researchers whether they warded off fusarium wilt under high disease pressure, Zhao said. Grafting with selected rootstocks as a cultural practice is viewed as an integrated disease management tool in the toolbox for watermelon growers to consider when dealing with fusarium wilt “hot spots” in the field, she said. However, most squash rootstocks are generally more susceptible to root-knot nematodes, a potential challenge with using grafted plants. Other UF/IFAS researchers are tackling that issue.
The new UF/IFAS study is published in the Journal of the Science of Food and Agriculture.
Strawberry season in the Northeast U.S. traditionally lasts only four to six weeks. However, researchers working on the multi-state TunnelBerries project were picking day-neutral strawberries in Durham last November. Last year, researchers harvested strawberries grown in low tunnels for 19 consecutive weeks from mid-July through the week of U.S. Thanksgiving. They also found that the low tunnels significantly increased the percentage of marketable fruit, from an average of about 70 per cent to 83 per cent.
Now in its second year, the TunnelBerries research project is being conducted at the UNH Woodman Horticultural Research Farm. It is part of a larger, multi-state U.S. Department of Agriculture-funded initiative to optimize protected growing environments for berry crops in the upper Midwest and northeastern United States. UNH’s component is focused on improving berry quality and the role day-neutral varieties may play in extending the length of strawberry season in the Northeast.
“[Strawberries] are a very valuable early season crop for farmers,” said graduate student Kaitlyn Orde, who is working with experiment station researcher Becky Sideman on the project. “Unfortunately, though, this season is very brief, limiting the period in which … producers are able to meet consumer demand for the fresh fruit. A longer strawberry season is good for both grower and consumer.”
The UNH project consists of two parts. Researchers want to determine the yield and fruiting duration of day-neutral strawberry varieties. Day-neutrals are a different plant-type than the traditional June-bearers; day-neutrals (or ever-bearing) have been shown to fruit continuously for four to six months in the region. In addition, day-neutrals fruit the same year they are planted, which is not the case with June-bearers.
“We are growing one day-neutral variety on three different mulches to determine if there are any differences in total production, production patterns, runner production, and fruit characteristics among the mulches,” Orde said. “We also are investigating the role plastic covered low-tunnels play in improving berry quality, and what the microenvironment is within low tunnels, especially late season. To do this, we are evaluating five different plastics for the low tunnels.”
Researchers in Maryland, Minnesota, North Carolina, and New York have conducted preliminary research on similar systems. There also are limited growers in the Northeast who already cultivate day-neutral varieties, and even fewer who have experimented with low-tunnels in combination with the strawberry crop.

In 2016, Canadian and United States fruit growers increased their production, but didn't necessarily see the demand to match, leading to an oversupply and lower prices for many fruit sectors. As a result, Farm Credit Canada’s (FCC) agriculture economists are predicting a mixed outlook for fruit growers in 2017.
“It’s a balancing act to produce enough fruit to meet demand, but not so much as to cause an oversupply that puts downward pressure on prices,” said J.P. Gervais, FCC chief agricultural economist. “Fortunately, a low Canadian dollar has been supporting prices for Canadian fruit producers and will help offset the full impact of a large supply in some sectors of the industry.”
Gervais added the real benefit will be to the Canadian consumer, who may see lower prices for some fruit – such as apples – at the grocery store.
Wine-making grapes fetch better prices
Grapes that are grown for wine-making in Ontario and British Columbia squeezed out an average three per cent price increase, which helped offset the lower prices for fresh grapes in 2016. Overall, the industry had a good year in 2016, as production increased by 22 per cent from the previous year.
Market prices for grapes are mixed based on the variety, quality and the end use, however, prices currently remain strong for wine grapes as demand is expected to continue growing in 2017.
Increased cranberry yields help offset lower prices
The cranberry industry has had several years of low prices due to growing North American supplies of cranberries.
In Canada, acreage devoted to growing cranberries has remained steady in British Columbia, but has increased in Quebec over the past five years. While prices remain low, rising production and better yields have compensated for low prices, boosting farm cash receipts.
In 2016, Canadian cranberry receipts reached a record $132.6 million, for an increase of 8.8 per cent, an all-time record high. There is also a growing demand for specialized markets segmentation in the cranberry industry, such as organic. Profitability depends on producers’ ability to continually improve their productivity.
Large 2016 harvest pushes apple prices lower
Canadian apple production was up 14 per cent while U.S. apple production increased by four per cent from 2015.
Agriculture and Agri-Food Canada’s monthly apple storage report indicates apple supplies are 98 per cent higher than last year’s level, so a large supply remains a challenge. As a result, Canadian retail apple prices are down 13 per cent in the first quarter of 2017 compared to the same period in 2016, but still remain above the previous five-year average. The same trend has impacted U.S. fresh apple market prices, which are down 12 per cent in 2017 and remain near the previous five-year average.
The U.S. Department of Agriculture’s Fruit and Tree Nuts Outlook indicates that 2017 apple prices should remain below 2016 levels given storage numbers. This price pressure is expected to persist until inventories decline.
According to Statistics Canada, in 2015, 31.5 per cent of Canadians aged 12 and older, roughly nine million people, consumed fruit and vegetables five or more times per day.
To celebrate the international fruit day on July 1, Canadians can eat more fruit throughout 2017 knowing their local grocery store will likely be well stocked with delicious and reasonably-priced Canadian fruit this summer and fall.

According to the Idaho Farm Bureau Federation, every spring farmers plant more than 320,000 acres of potatoes valued at between $550-$700 million. Yet unbeknownst to most consumers, roughly 30 percent of the potatoes harvested spoil before they reach a grocery store shelf.
Boise State University researchers Harish Subbaraman, David Estrada and Yantian Hou hope to change that.
In a recently awarded one-year $413,681 Idaho Global Entrepreneurial Mission (IGEM) grant, Boise State is collaborating with Idaho State University and industry partners Isaacs Hydropermutation Technologies, Inc (IHT) and Emerson to develop a wireless sensor network that would be able to detect temperature, humidity levels, and carbon dioxide and ammonia levels in real time, to help with early detection of rot.
The cloud-enabled sensor system will feature three-dimensional hot spot visualization and help predict on-coming rot or deteriorating quality of stored potatoes. This will allow owners to use the real-time sensor data, along with a miniature air scrubber system IHT is developing, to respond to potential problems quickly, as they develop.
“The current problem is, there are no sensors that can do early detection of rot,” said Subbaraman, an assistant professor of electrical engineering. “But if you can identify rot at an early stage, you can prevent crop loss on a large scale.”
“Rot spreads on contact. The way the system works now is, a farmer walks into their facility, smells rotten potatoes and that’s it,” added Estrada, an assistant professor of materials science. “But our sensors can detect parts per million, or even parts per billion, and can tell us in exactly which bin the sensor is detecting rot. That way, farmers can go out, pull out a few rotten potatoes and save the rest of the batch.”
Estrada explained that the cost of printing sensors could be as low as a few dollars apiece. Not only would the monitoring system hopefully prevent waste, it could help preserve the quality of potatoes in the facility.
Subbaraman and Estrada plan to have their sensors tested in a facility by the end of their year-long grant cycle by working with industry partner Emerson PakSense. But Estrada points out that this project has been three years in the making and will continue long past the IGEM grant.
“The College of Business and Economics and the College of Engineering have been invested in building a printed electronics community in Idaho for several years,” Estrada said. “Most recently, our Advanced Nanomaterials and Manufacturing Laboratory has partnered with the NASA Ames Research Center, Air Force Research Labs, and American Semiconductor to develop flexible electronics technologies.”
Subbaraman noted, “We’re also very interested in partnering with others interested in this technology. It’s a great economic impact for the state and we see that growing in the future.”
Not only would the cloud-enabled wireless sensory system save Idaho farmers millions in revenue, it could have a billion-dollar impact on the national potato industry and help address larger socio-economic issues such as food scarcity in parts of the world.
“The benefit of this system is it’s extremely low cost,” Subbaraman added. “This dual detection and air scrubbing system could later be extended to other stored crops as well.”
As part of Phase I of the National Science Foundation Grant, Harvest CROO Robotics is developing software and hardware tools. They include the vehicle’s GPS navigation system, LIDAR technology, and other camera and sensor features.
The mobile platform is a modified version of a Colby Harvest Pro Machine. With four-wheel steering, turning movement will be smooth and precise, providing a zero turning radius for greater maneuverability than a standard tractor. Special levelling hardware and software has been developed and added to allow the vehicle to compensate for varying bed heights.
The vehicle will carry 16 picking robots through the field and span 6 beds of plants, picking the four middle beds. The Harvest CROO machine is equipped with a dual GPS system. The Harvester uses both GPS systems to interpolate the position of the platform to be able to position the robots precisely over the plants.
“Having the machine navigate the fields autonomously is the culmination of years of work and prototyping,” said Bob Pitzer, Co-Founder and CTO of Harvest CROO. “It is very gratifying to see our team effort come to fruition.”
Harvest CROO Robotics continues to develop and test the latest technology for agricultural robotics. Using the proprietary vision system, all ripe berries will be harvested from the plants.
The fruit will then be transferred up to the platform level of the machine using a series of conveyers. There, the packing module of the machine will perform a secondary inspection and grade the fruit.
Depending on quality, it will either be packed into consumer units, diverted to process trays, or discarded. The use of this technology will improve the quality of the berries picked, reduce energy usage, and increase strawberry yields.
In December, the National Science Foundation awarded a grant worth up to $1 million. Harvest CROO Robotics used part of these funds to bring several highly qualified and experienced individuals on board the project. Scott Jantz, Electrical Engineering Manager, said, “We all feel like we are part of something special.”
While fundraising for the project has been ongoing, the current investment round will likely be closed at the end of July, when field testing of the vehicle is completed. “We will possibly open a new investment round early next year, at a higher valuation.”, stated Gary Wishnatzki, Co-Founder. “The new unit price will reflect the successful deployment of the Alpha Unit, a key milestone.”
