Wageningen University & Research uses computer models to develop sustainable management strategies in the control of potato late blight, caused by Phytophthora infestans. At the moment, large amounts of fungicides are used to control the disease. Organic farmers face an additional challenge because they are not allowed to use these chemicals. From an environmental point of view, these chemicals are also very polluting and therefore sustainable late blight management strategies are needed. In Ph.D research study, computer models have been used to investigate how the disease spreads in an agricultural landscape and to analyze the effect of growing resistant varieties.In Francine Pacilly's Ph.D. research, computer models have been used to investigate how the disease spreads in an agricultural landscape and to analyze the effect of growing resistant varieties. These models show that an increase in the number of potato fields with resistant varieties increases the risk that aggressive strains of the pathogen emerge and spread. This risk decreases if more than 50 per cent of the acreage of potato fields consists of resistant varieties. So, many resistant potatoes are not yet available so alertness is required. Various strategies are available to limit the consequences of a breakthrough, for example the spatial allocation of crops in combination with the use of small amounts of fungicides to limit the environmental impact. In addition, growing resistant varieties with multiple resistance genes reduces the risk of susceptibility to the potato disease. It is expected that these type of varieties will enter the market soon.Last year workshops with farmers were organized to increase awareness about the risk of resistance breakdown. In these workshops, the computer model was used to present several model scenarios to conventional and organic farmers. These workshops were very useful for showing farmers how the disease spreads in a landscape over time and space and for showing the effects in the long term. After the workshop farmers agreed that resistance management is important to increase the durability of resistant varieties and that collaborative action is needed. The workshops were useful to bring farmers together and to discuss strategies in the control of late blight to reduce the impact of the disease.In order to develop sustainable strategies it is important to consider all factors that influence late blight control such as the disease, the crop and control strategies of farmers. This research is part of the Complex Adaptive Systems program of Wageningen University where the goal is to identify these factors and to analyze how they influence each other. Potato late blight as one system brings a future without chemical control closer.
Canadian vegetable growers spend hundreds of thousands of dollars each year on herbicides that don’t kill the weeds they are targeting. Not only do these herbicide-resistant weeds cause farmers yield losses, but also the farmers often find themselves paying for multiple weed control strategies, including hiring workers to manually remove the weeds.
Five new fertilizer-compatible products are expected to be available from Vive Crop Protection for U.S. corn, sugarbeet and potato growers in 2019. Each product includes a trusted active ingredient that has been improved with the patented Vive Allosperse Delivery System.AZteroid FC 3.3 is a high-concentration, fertilizer-compatible fungicide that improves plant health, yield and quality of key field crops, including potatoes, sugarbeets and corn. AZteroid FC 3.3 controls seed and seedling diseases caused by Rhizoctonia solani and certain Pythium spp. It contains azoxystrobin, the same active ingredient as Quadris.Bifender FC 3.1 controls corn rootworm, wireworm and other soil-borne pests in corn, potatoes and other rotational crops. Bifender FC 3.1 has a new high-concentration, fertilizer-compatible formulation and contains bifenthrin (same as Capture LFR).TalaxTM FC fungicide provides systemic control of pythium and phytophthora, similar to Ridomil Gold SL but in a fertilizer-compatible formulation. Talax FC contains metalaxyl and helps potatoes and other crops thrive right from the start, resulting in improved yield and quality.MidacTM FC systemic insecticide is a fertilizer-compatible imidacloprid formulation that controls below-ground and above-ground pests in potatoes and sugarbeets. It provides the same long-lasting protection of Admire PRO but with the convenience of being tank-mix compatible with fertilizers, micronutrients and other crop inputs.AverlandTM FC insecticide is a fertilizer-compatible abamectin formulation that controls nematodes in corn. It also controls potato psyllid, spider mites, Colorado potato beetle and leaf miners in potatoes. In-furrow application trials for nematode control in a wide range of crops are under way.All of these fertilizer-compatible products use the Vive Allosperse Delivery System - the first nanotechnology registered for U.S. crop protection. Products containing Allosperse are the best mixing products on the market, whether they are used with each other, liquid fertilizer, other crop protection products, micronutrients or just water.Brent Petersen, president of Cropwise Research LLC, performed trials on behalf of Vive Crop Protection to test mixability of the company’s products. During spring 2018, he mixed all five of the new products together with liquid fertilizer and observed, “We didn’t see any separation or settling out. It was nice to see because we often see products that aren’t compatible with other products, and especially with liquid fertilizer.”EPA registration is pending for Talax FC, Midac FC and Averland FC and the new formulations of AZteroid and Bifender.
The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registrations for Venture L Herbicide for control of labeled weeds on rhubarb, the bulb onion subgroup 3-07A, green onions, caneberries subgroup 13-07A and lettuce in Canada.

Researchers are combining new digital tools, computer technologies and machine learning to bring cost-effective weed control solutions to the field. Although still in the early stages, this new high-tech solution is being designed as an advanced spot-spraying precision technology that will help farmers reduce input costs and add another management tool to their integrated management systems.
January 8, 2018, Guelph, Ont – The Pest Management Regulatory Agency (PMRA) recently announced the approval of minor use label expansion registration for Prowl H2O herbicide for control of labeled weeds on transplanted field tomatoes grown in mineral soil in Canada. Prowl H2O was already labeled for use on a number of crops in Canada for control of several weeds. This minor use project was submitted by Ontario as a result of minor use priorities established by growers and extension personnel. Prowl H2O herbicide is toxic to aquatic organisms and non-target terrestrial plants. Do not apply this product or allow drift to other crops or non-target areas. Do not contaminate off-target areas or aquatic habitats when spraying or when cleaning and rinsing spray equipment or containers. In field tomatoes, do not apply Prowl H2O more than once in two consecutive years. Follow all other precautions, restrictions and directions for use on the Prowl H2O herbicide label carefully. For a copy of the new minor use label contact your local crop specialist, regional supply outlet or visit the PMRA label site.
“Samurai Wasps vs. Stink Bugs” is not the title of the latest Avengers film. But it does describe new efforts by Cornell scientists to control a household nuisance and agricultural pest.
Food-borne illness can create big problems for both public health and a business. Most recently, an outbreak of E. coli made headlines across Canada and the U.S., with 29 confirmed cases in Canada. Romaine lettuce and other leafy greens were recalled by producers and food manufacturers after the outbreak was traced back to farms in California.
Protecting the health and safety of Canadians and the environment is a priority for the Government of Canada. This includes helping to protect the health of bees and other pollinators by minimizing their exposure to pesticides.
