February 23, 2018, Niagara Falls, Ont – Apple and lavender grower Harold Schooley and crop protection specialist Craig Hunter are the winners of the 2018 Ontario Fruit and Vegetable Growers’ Association (OFVGA) Industry Award of Merit.

It’s the first time in the organization’s history that two winners were selected in the same year. The awards were presented recently at the OFVGA annual banquet in Niagara Falls.

Schooley has farmed in Norfolk County since the mid-1970s, growing apples and more recently adding lavender production to his family’s operation. He joined the OFVGA board of directors as chair of the research section in 2004, a role he has held until the section was retired this year.

“Growers rely on research to help advance the industry and we appreciate Harold’s many years of service on our behalf to ensure we get the research we need to grow our markets and maintain our competitiveness,” says Jan VanderHout, OFVGA chair. “Harold’s insights and expertise have been valued additions, both to our board table and to the fruit and vegetable industry as a whole.”

During his tenure as research section chair, Schooley reviewed hundreds of research proposals for industry relevance, attended countless research-related meetings and events, and represented the grower viewpoint during research priority setting exercises. He is a board member and past chair of Ontario Agri-Food Technologies, an active member of the Norfolk Fruit Growers, and was previously involved with the now-defunct Ontario Apple Marketing Commission.

Schooley is also a past recipient of the Golden Apple Award, which recognizes individuals for outstanding contributions to the apple industry. He holds a Bachelor of Science degree in Agriculture and a Masters’ in Plant Pathology, both from the University of Guelph, and lives with his wife Jan on their third generation family orchard near Simcoe.

Hunter has dedicated his career to crop protection, spending 30 years with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) before joining the OFVGA to work on behalf of horticulture growers and becoming an industry-renowned expert in the process.

“As growers we’ve been very fortunate to have Craig’s skills and expertise at our disposal to help ensure access to new crop protection materials and keep old ones available,” says Charles Stevens, OFVGA crop protection chair. “He is a valued and respected resource in global crop protection circles and his efforts on behalf of growers have been invaluable to our industry.”

Hunter helped establish the Pest Management Centre in 2003, Canada’s hub for improving access to newer, safer pesticides as well as promoting novel production practices that reduce agriculture’s reliance on pesticides, and was also instrumental in helping start the Ontario Pesticide Education Program more than 30 years ago.

He’s the longest serving member of the provincial Ontario Pesticide Advisory Committee, chairs the national Minor Use Priority Setting meetings, and is a driving force behind the Global Minor Use Summits that are working towards global registration for crop protection products. Hunter lives in Simcoe with his wife, Jane, and is a graduate of the University of Guelph, holding a Bachelor of Science in Agriculture and a Masters’ in Environmental Biology.

The OFVGA Award of Merit is presented annually to an individual or an organization that has made outstanding contributions to the fruit and vegetable industry.

February 20, 2018, East Lansing, MI – This article provides a brief summary of some of the research being produced by some of the institutions participating in a project titled “Management of Brown Marmorated Stink Bug in U.S. Specialty Crops” funded by the United States Department of Agriculture (USDA) and National Institute of Food and Agriculture (NIFA). It is not a detailed summary of all the work being conducted within this project, but provides highlights from areas of the project that may be of interest to growers.

Researchers continue to track the movement and abundance of brown marmorated stink bugs. The largest populations and the most widespread damage to tree fruits is in the Mid-Atlantic region. In Michigan, we have seen brown marmorated stink bug numbers slowly build and currently the majority of the population is found in the southern third of the state with the highest numbers in the southern two tiers of counties. Damaging levels of brown marmorated stink bug do occur in localized areas north of this area and have produced fruit injury on individual farms north of Grand Rapids, Michigan, in the Ridge area.

The information required to detect the movement and relative numbers comes from trapping. A great deal of effort has gone into finding the most effective trap and lure. A variety of trap styles exist, but the pyramid trap baited with an attractant lure has been the standard way to detect brown marmorated stink bugs. Lures continue to be improved and the current standard is a two-part lure comprised of an aggregation pheromone and an attractant from a related stink bug.

A side-by-side comparison of the pyramid trap with an easier to use clear sticky trap on a 4-foot wooden stake using the same two lures has shown that the pyramid trap catches more stink bug adults than the clear sticky trap early in the season, and more adults and nymphs late in the season, but similar numbers mid-season. Importantly, the number of captured stink bugs on the clear sticky traps is positively correlated with the catch from the pyramid traps, which means the clear sticky traps could replace the pyramid traps and be used to determine presence, relative numbers and seasonal movement.

The pyramid trap was improved by replacing the dichlorvos strip killing agent with a piece of pyrethroid-impregnated netting. The pyrethroid in this case is deltamethrin. The netting is similar to mosquito netting used in malaria prevention programs and is commonly referred to as long-lasting insecticide netting. The benefits are that it lasts for the entire trapping season and is much safer to handle due to its low mammalian toxicity. Long-lasting insecticide netting also shows promise as a means of trapping brown marmorated stink bugs.

The most promising biological control agent continues to be a wasp parasitoid (parasites do not kill their host, but parasitoids do kill them) known as the samurai wasp, Trissolcus japonicas. This tiny wasp puts its own eggs into the stink bug’s eggs, and the developing wasp larvae use the stink bug egg for food until they emerge. In Asia, where brown marmorated stink bug originally came from, 60 to 90 percent of the eggs are parasitized by this wasp. Researchers in the U.S. have determined that the wasp highly prefers brown marmorated stink bug eggs over one of our native stink bugs eggs, spined soldier bug, so they should have little-to-no impact on them.

The USDA has yet to approve the general release of these wasps, but it is under review and could potentially happen at any time. Interestingly, like brown marmorated stink bugs, this wasp has been transported across the ocean. To date, populations have been detected in some Mid-Atlantic states and the Pacific Northwest and are slowly spreading on their own. However, if permission would be given by the USDA, they could be mass-reared and released where they would produce the greatest benefit.

Additionally, other brown marmorated stink bug predators and parasites, ones native to the U.S., have been identified and are being evaluated for their effectiveness. The particular insects attacking brown marmorated stink bugs vary according to habitat in each area. So far, the incidence of attack for these homegrown natural enemies of brown marmorated stink bugs is low.

Another area of interest is looking for ways to protect natural enemies from the negative effects of control procedures used against brown marmorated stink bugs. By carefully managing insecticide use, natural enemies may be preserved. One way to manage insecticide use is by establishing threshold levels for the pest. Determining an accurate threshold level requires testing over several years and in many orchard environments.

Research in West Virginia apple orchards has shown that a threshold of 10 brown marmorated stink bugs per trap can lower insecticide use by 40 percent compared to a grower standard program. A different trapping study compared brown marmorated stink bug captures in traps placed adjacent to wooded areas next to orchards to traps placed within orchards. The interior placement resulted in fewer nymphs captured, but adult catch was similar. However, there is still no clear relationship between the number of brown marmorated stink bugs captured in a trap and the amount of injury this level will cause in the orchard.

Insecticide assays in North Carolina showed that out of four Organic Materials Review Institute (OMRI)-approved materials – Entrust, Neemix, Pyganic, Azera – Entrust was the most harmful to two native parasitoid wasp species, even when exposed to 0.1-times the field rate. However, when exposed to residues of sugar-laced pesticides, only the lowest rate of Neemix had no impact.

In an Oregon study, more than half of the wasps exposed to dry residues of Actara, Asana or Admire Pro died within an hour of exposure. After 24 hours, mortality was greater than 75 per cent for those materials and for Entrust and Exirel, but not for Altacor.

A promising management tactic is attract-and-kill using pheromone-baited perimeter trees that receive either a regular insecticide application or have long-lasting insecticide netting within the canopy. Seven- and 14-day spray intervals using attract-and-kill or perimeter sprays were compared to 10 adults per trap (cumulative) threshold sprays of two alternate row middle applications and to a control. If the cumulative threshold level was met in the attract-and-kill or in the threshold spray plots, it also triggered two consecutive alternate row middle sprays.

Fruit injury was significantly reduced in the apple blocks using the perimeter sprays on seven- or 14-day intervals in the blocks using attract-and-kill with sprays at seven- and 14-day intervals or with long-lasting insecticide netting, and in blocks treated after reaching threshold levels of brown marmorated stink bugs, compared to the grower standard. This suggests perimeter sprays are an effective management tactic to employ against brown marmorated stink bugs.

Long-lasting insecticide netting placed in attract-and-kill trees in a vertical orientation killed more brown marmorated stink bugs than when the fabric was oriented horizontally. The level of injury to peaches and apples under grower standard programs was similar to the injury found when just orchard perimeters consisting of the exterior row plus one row toward the interior were sprayed. This did not hold for peaches if the orchard was 10 acres or more in size.

Another use of long-lasting insecticide netting is to drape a 5-foot by 5-foot section of it over a pole or fence and attach an attractant to the netting. Several of these are placed on the orchard perimeter between woods and the orchard. Brown marmorated stink bugs attracted to the lure come into contact with the pesticide in the netting and die. This may allow for interception of the adults before they enter the orchard resulting in less fruit damage.

Multi-state research efforts allow researchers to quickly acquire information that would take individual states or regions many years by themselves. Most of these experiments will be repeated in 2018 and new ones will be added as we continue to grow the knowledge base that allows us to successfully meet the challenges that brown marmorated stink bugs bring to the tree fruit industry.

February 1, 2018, Madison, WI – The Colorado potato beetle is notorious for its role in starting the pesticide industry – and for its ability to resist the insecticides developed to stop it.

Managing the beetle costs tens of millions of dollars every year, but this is a welcome alternative to the billions of dollars in damage it could cause if left unchecked.

To better understand this tenacious pest, a team of scientists led by University of Wisconsin–Madison entomologist Sean Schoville sequenced the beetle’s genome, probing its genes for clues to its surprising adaptability to new environments and insecticides. The new information sheds light on how this insect jumps to new plant hosts and handles toxins, and it will help researchers explore more ways to control the beetle.

Schoville and colleagues from 33 other institutes and universities report their findings in the Jan. 31, 2018 issue of Scientific Reports.

The Colorado potato beetle’s rapid spread, hardiness, and recognizable tiger-like stripes have caught global attention since it began infesting potatoes in the 1800s. The beetle was investigated as a potential agricultural weapon by Germany in the 1940s and its postwar spread into the Soviet bloc stoked an anti-American propaganda campaign to pin the invasion on outsiders. More benignly, it has been featured on many countries’ stamps and is used in classrooms to educate about insect lifecycles.

But it was the beetle’s ability to rapidly develop resistance to insecticides and to spread to climates previously thought inhospitable that has fascinated and frustrated entomologists for decades.

“All that effort of trying to develop new insecticides is just blown out of the water by a pest like this that can just very quickly overcome it,” says Schoville. “That poses a challenge for potato growers and for the agricultural entomologists trying to manage it. And it’s just fascinating from an evolutionary perspective.”

Within the beetle’s genome, Schoville’s team found a diverse and large array of genes used for digesting plant proteins, helping the beetle thrive on its hosts. The beetle also had an expanded number of genes for sensing bitter tastes, likely because of their preference for the bitter nightshade family of plants, of which potatoes are a member.

But when it came to the pest’s infamous ability to overcome insecticides, the researchers were surprised to find that the Colorado potato beetle’s genome looked much like those of its less-hardy cousins. The team did not find new resistance-related genes to explain the insect’s tenaciousness.

“So this is what's interesting – it wasn't by diversifying their genome, adding new genes, that would explain rapid pesticide evolution,” says Schoville. “So it leaves us with a whole bunch of new questions to pursue how that works.”

Schoville and his collaborators see their research as a resource for the diverse group of scientists studying how to control the beetle as well as its life history and evolution.

“What this genome will do is enable us to ask all sorts of new questions around insects, why they’re pests and how they’ve evolved,” says Yolanda Chen, a professor at the University of Vermont and another leader of the beetle genome effort. “And that’s why we’re excited about it.”

The genome did provide a clue to the beetle’s known sensitivity to an alternative control system, known as RNA interference, or RNAi for short. The nucleic acid RNA translates the genetic instructions from DNA into proteins, and RNAi uses gene-specific strands of RNA to interfere with and degrade those messages. In the beetle, RNAi can be used to gum up its cellular machinery and act as a kind of insecticide. The Colorado potato beetle has an expanded RNAi processing pathway, meaning it could be particularly amenable to experimental RNAi control methods.

Schoville and Chen are now sequencing another 100 genomes of the Colorado potato beetle and its close relatives to continue investigating the hardiness and adaptability that have captured so many people’s attention for the past 150 years.

December 20, 2017, Saguenay, Que – Common scab is one of the most important diseases affecting potato crops worldwide. But researchers with the Université du Québec à Chicoutimi have discovered that using fresh residues and/or bio-products from Canadian goldenrod (Solidago canadensis) may offer an alternative to conventional fumigants.

In the study, researchers conducted a preliminary investigation of the utilization of S. canadensis to reduce common scab severity, and determined the allopathic potentials of S. canadensis extracts on Streptomyces scabiei (also known as S. scabies).

Compared with control plants, preliminary results showed that adding 1.2 kg of fresh S. canadensis residue per m2 reduced scab severity by about 45 per cent. Furthermore, concentrations of hexane and dichloromethane extracts from S. Canadensis inhibited the growth of S. scabiei by about 97 per cent.

The results were comparable with those using tetracycline, a known inhibitor of S. scabiei.

Both experiments suggested that S. canadensis may represent a new approach for controlling potato common scab. More studies are required to better understand the mechanisms involved in S. canadensis induced reduction of common scab in order to standardize the approaches.

December 12, 2017, Guelph, Ont – Syngenta Canada Inc. recently announced that Orondis Ultra fungicide is now available in a premix formulation.

Orondis Ultra combines mandipropamid (FRAC Group 40) with oxathiapiprolin (FRAC Group 49) to provide protection against late blight (Phytophthora infestans).

Orondis Ultra works through translaminar and acropetal activity, moving across the leaf surface as well as upwards into new growth via the plant’s xylem, or water-conducting vessels. Both modes of action protect the plant during periods of active growth.

Previously, a case of Orondis Ultra contained two components – Orondis Ultra A and Orondis Ultra B – that required individual measuring and tank mixing.

Now, the new premix formulation has a single product label, meaning the components no longer require mixing prior to use, and will be available in a 4 x 3.78 L case.

“Weather conditions in-season can create the conditions needed for late blight to develop and thrive,” explains Eric Phillips, product lead for fungicides and insecticides with Syngenta Canada. “The new Orondis Ultra premix formulation helps make proactive late blight management more convenient for growers.”

Orondis Ultra is also registered for aerial application in potatoes.

In addition to potatoes, Orondis Ultra can be used on head and stem brassica vegetables, including broccoli and cabbage, bulb vegetables, such as onion and garlic, leafy vegetables, such as arugula and celery, and cucurbit vegetables, including cucumber and squash. See the Orondis UItra label for a complete list of crops and diseases.

Orondis Ultra will be available for purchase as a premix formulation for the 2018 season.

While most young men in the early 1900s were likely dreaming about driving a Model-T Ford, Norman M. Bartlett was thinking in an inventive way.

Living in Beamsville, Ontario – the heart of the Niagara Peninsula – had a strong influence on the direction of his thinking. The Niagara Peninsula has possibly the most unique combination of fertile soil types, climatic conditions and access to local markets in Canada.

It is also interesting to note that even at the turn of the century, the consumer was recognizing quality and placing demands on the growers to improve produce quality. This interest in quality plus quite possibly the fact that the major variety of pears grown in this area was (and still is) the Bartlett pear, (an interesting coincidence), were most probably the factors that strongly influenced Norman M. Bartlett’s life in 1912. During that year, he began manufacturing lime sulphur in a 40-inch cast iron kettle and thereby established Bartlett Spray Works. His product was excellent by 1912 standards, and Bartlett gained notoriety with this product as it helped to produce the quality crops the consumer desired. It was not long before other products were added to his list of crop protection materials and demand was spreading into the other fruit and vegetable growing areas of Ontario. Quality and service were synonymous from the very beginning.

Bartlett was a fruit grower as well during this time. The Bartlett farm on Bartlett Side Road in Beamsville consisted of a mixture of apples, grapes and pears – mostly Bartlett pears, of course. A grass-rooted involvement and extreme interest in trying to solve problems and find answers that were sound and profitable to not only Bartlett Spray Works, but to the growers he was serving then evolved. This would become the cornerstone of the foundation that N.M. Bartlett Inc. would still be building on some three generations and more than 80 years later.

Over the next quarter-century, Bartlett Spray Works continued to grow in both product range and geographical coverage. Products such as Paris Green, Bluestone (Copper Sulphate), Microfine Wettable Sulphur, Calcium Arsenate, Nicotine Sulphate, and Arsenate of Lead, to name but a few, were found under the Bartlett label. By this time, Bartlett had designed and built his own hammer mill and cyclone separator to be able to produce the finest ground sulphur in North America.

Bartlett Microfine Sulphur was known to growers as the best available. Soon word spread to other industries and Bartlett Microfine Sulphur was used extensively in the manufacture of rubber and explosives in Eastern Canada by companies such as Firestone, Uniroyal, CIL, and Dupont. When the use of dusts became the newest application method during the 1950s, Bartlett Spray Works met the challenge to produce quality products. The grind mill became instrumental in producing high quality superfine dusts.

The involvement of other Bartlett family members was also critical to the success of the company, which was incorporated in 1951 and renamed N.M. Bartlett Manufacturing Company. The three Bartlett children – Evelynne, Jim and George – all were involved in the family business. The children first helped out on the farm and, when old enough, became active in the spray works. George and his future brother-in-law, Hec Little, directed a staff of six involved in production, Evelynne managed the office and billing, and Jim looked after deliveries of the product, which included deliveries to the province of Quebec by the 1940s.

From the beginning, Norman had an inventive mind and enjoyed challenges. Therefore, it was not surprising that he designed and built fruit grading and sorting equipment as early as 1930. The Bartlett equipment set a world standard for excellence of handling fruit and vegetables. In fact, during the 1950s and 1960s, Bartlett equipment was built for growers in the United Kingdom, South Africa, Australia, New Zealand, Italy, Israel, France, and United States as well as Canada.

In Canada, this equipment introduced the Bartlett name into other areas of the country. Bartlett equipment and the Bartlett reputation became know to all fruit and vegetable growers from coast to coast. All of these additions to the Bartlett line complemented the crop protection products, which remained the mainstay of the overall business.

Jim Bartlett took over the leadership of the company in the late 1950s when his father, Norman, suffered a stroke. After a full and eventful life with many credits to his name, Norman passed away in 1970 at the age of 77.

During the late 1960s and 1970s, the next generation of the Bartlett family became involved. The company name changed to N.M. Bartlett Inc. during the late 1970s and growth through service and commitment remained strong. The leadership provided by Jim to the company blossomed out into the industry.

Jim spent considerable time and effort working for effective policy. He advocated tirelessly on behalf of the industry to the federal government on issues of cross border importation. He championed the first minor use registration of pesticides program in Canada in 1977 to help keep Canadian horticultural growers competitive. And he was an early promoter of the need for federal help to bring new crop protection products to the small acre crops that make up the diverse horticulture industry in Canada.

Jim served as chair of the national organization now known as CropLife Canada and was involved in the creation of the CropLife Ontario Council – working to balance the interests of the industry with the interests of society.

He was an active member of a group that brought the first Ontario horticultural conference in Toronto. Today, that annual event is known as the Ontario Fruit and Vegetable Convention and Jim’s grandson, Matt Peters, has served as its president. He’s one of eight grandchildren that represent the fourth generation in the Bartlett family business.

Jim continued to be actively involved in all the aspects of the business until 1981, when he had a severe heart attack. At that time, his brother-in-law, Hec Little, son-in-law Don Peters, and son, Craig Bartlett, became the management nucleus with Jim serving as a semi-retired advisor. This management team oversaw a broadening sales force of 13 across Canada and continued successfully through the 1980s. When Jim retired in 1987, he was elected as Chairman of the Board, and his son, Craig Bartlett, became president of the company.

Jim passed away in 2011, one year shy of the business celebrating 100 years. He was conducted into the Canadian Agricultural Hall of Fame in November 2016, recognized as a visionary, passionate advocate and respected voice in Canadian agriculture. He left behind a lasting legacy in a family business that continues to have a positive impact on Canadian horticulture.

The values set out by Norman and Jim have been carried forward in the third and fourth generation’s business goals and commitments. Service and dedication to the horticultural industry in Canada is still first and foremost.

In the words of Craig Bartlett: “We at N.M. Bartlett Inc. are proud of the heritage and values that the first two generations established, and the company looks forward to a future where we will continue to apply these time-tested values.”

Norman Bartlett himself would have been proud of the accomplishments to date of the little, privately-owned family business he started 105 years ago.

Phosmet – https://onvegetables.files.wordpress.com/2017/08/phosmetprvd2017-07.pdf

The decisions state that lambda-cyhalothrin poses an unacceptable risk from dietary exposure (worst case scenario cumulative food residues would be too high), while phosmet poses a risk during application and post-application activities. The proposed precautions such as revised restricted entry intervals would not be agronomically feasible (e.g. 12 day REI for scouting carrots, 43 days for moving irrigation pipe).

Public consultation is now open until September 23 (lambda-cyhalothrin) or September 30 (phosmet) so if growers wish to make comments on these proposed decisions you can submit them to This e-mail address is being protected from spambots.

August 11, 2017, Toronto, Ont – Vive Crop Protection recently announced a new partnership with four biopesticide manufacturers to develop new and improved biopesticides, supported by Sustainable Development Technology Canada (SDTC).

Biopesticides are the fastest growing crop protection segment, but have suffered from limited effectiveness in field situations, shorter product life, poor compatibility with conventional pesticides, and limited combination products. Vive has recently demonstrated that the Allosperse Delivery System enhances the viability and performance of biopesticides.

“This project extends the scope of the Allosperse Delivery System and means that we can provide a complete solution to growers, whether they need a conventional, biological, or combination crop protection product,” said Keith Thomas, CEO of Vive. “We’re excited about the potential for these products and thank SDTC for the support.”

Over the next three years, Vive will work with the partner manufacturers to develop new and improved versions of their products. This work will be supported by SDTC.

Vive Crop Protection is developing environmentally-friendly pesticides made from organic matter,” said Leah Lawrence, president and CEO of Sustainable Development Technology Canada. “This Canadian-made technology represents an advancement in biopesticides that will deliver real economic and environmental benefits across Canada and around the world.”

July 26, 2017, Ontario - Stemphylium leaf blight (Stemphylium vesicarium) of onion starts as yellow-tan, water-soaked lesions developing into elongated spots. As these spots cover the entire leaves, onions prematurely defoliate thereby reducing the yield and causing the crop to be more susceptible to other pathogens.

Stemphylium was first identified in Ontario in 2008 and has since spread throughout the Holland Marsh and other onion growing areas in southwestern Ontario.

Stemphylium leaf blight can sometimes be misdiagnosed as purple blotch (Alternaria porri), as they both have very similar symptoms initially. Purple blotch has sunken tan to white lesions with purple centers while Stemphylium tends to have tan lesions without the purple centers.

Stemphylium spores are dispersed by wind. Spore sampling at the Muck Crops Research Station using a Burkard seven-day spore sampler detected an average of 33 spores/m3 in 2015 and seven spores/m3 in 2016.

In ideal conditions, leaf spot symptoms occur six days after initial infection. Stemphylium tends to infect dead tissue or wounds, often as a result of herbicide damage, insect feeding or from extreme weather.

Older onion leaves are more susceptible to infection than younger leaves and symptoms are traditionally observed after the plants have reached the three- to four-leaf stage.

Over the last few years, Botrytis leaf blight (Botrytis squamosa) has become less of an issue and has been overtaken by Stemphylium as the most important onion disease — other than maybe downy mildew.

This may be because the fungicides used to target Stemphylium are likely managing Botrytis as well. Since Stemphylium can be so devastating and hard to control, fungicides are now being applied earlier in the season which may be preventing Botrytis to become established.

Botrytis squamosa overwinters as sclerotia in the soil and on crop debris left from the previous year and infects onions in mid-June when temperatures and leaf wetness are favourable for infection. In the Holland Marsh, Stemphylium lesions were first observed on June 29, 2015 and July 7, 2016.

The primary method of management is through foliar fungicides such as Luna Tranquility, Quadris Top and Sercadis. Keep in mind that Sercadis and Luna Tranquility both contain a group 7 fungicide so remember to rotate and do not make sequential applications.

The effectiveness of these fungicides in the future depends on the spray programs you choose today. There are already Stemphylium isolates insensitive to several fungicides in New York so resistance is a real and very serious issue with this disease.

Remember to rotate fungicide groups with different modes of actions to reduce the possibility of resistance. A protective fungicide is best applied when the onion crop has reached the three-leaf stage, however it may not be necessary in dry years.

Research is currently being conducted at the Muck Crops Research Station to improve forecasting models to identify the optimal timing for commercial growers to achieve good control.

BOTCAST disease forecasting model is available in some areas of Ontario to help growers predict the activity of the disease. Warm, wet weather between 18-26°C is most favourable for disease development. Regular field scouting is still the best method to assess disease levels.

Plant spacing that permits better air movement and irrigation schedules that do not extend leaf wetness periods may be helpful in some areas. Recent work at the Muck Crops Research Station has shown that spores increase two to 72 hours after rainfall with eight hours of leaf wetness to be optimal for the pathogen. Irrigate overnight if possible so by morning the leaves can dry out and you don’t prolong that leaf wetness period.

To lower inoculum levels it is crucial to remove or bury cull piles and to bury leaf debris left from the previous year’s crop through deep cultivation. Stemphylium of onion has many hosts including leeks, garlic, asparagus and even European pear.

Take the time to rogue out volunteer onions or other Allium species in other crops nearby and remove unnecessary asparagus or pear trees to lower inoculum levels. As with any other foliar disease of onion, it is beneficial to rotate with non-host crops for three years.

To prevent the development of resistance, it is essential to always rotate between different fungicide groups and/or tank mix with a broad spectrum insecticide. Current products registered for Stemphylium leaf blight of onion are listed by fungicide group below:

Group 7 - Sercadis

Group 7/9 - Luna Tranquility

Group 11/3 - Quadris Top

The tip-and-pour method, as well as poorly designed pumps, can expose workers to injury and companies to significant financial losses.

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.

July 19, 2017 - In 2016, Health Canada’s Pest Management Regulation Agency (PMRA) completed a re-evaluation of carbaryl, a common chemical thinning regime for Canadian apple producers.

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]
As a result, research is underway to discover a new thinning regime for Canadian apple producers.

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!
