Until recently, New York onion farmers had just two insecticide options for controlling onion thrips, a pervasive insect pest, and neither was good. One was short-lived, the other was dangerous to work with – and both were losing effectiveness.

In 2018, MS Gregson introduced a line of electrostatic sprayers (the Ecostatik) in Canada. While electrostatic technology has been used in agriculture since the 1980’s, this is the first time ground rigs have been so readily available to Ontario (possibly Canadian) growers.

The corn salvage benefit for 2018 covers cases where DON (deoxynivalenol) levels in harvested corn exceed five parts per million (5 ppm). The benefit is designed to help producers cover costs to harvest and then market, use as feed or find an alternative use for damaged corn.

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.

Canada’s Pest Management Regulatory Agency [PMRA] recently announced it is restarting the review process for mancozeb.

All current final decisions and proposals regarding MRLs for mancozeb products will be removed and a new proposal for consultation will be posted.

The PMRA released its evaluation for mancozeb and metiram products in June 2018. According to that decision, all uses of products containing mancozeb (Manzate, Penncozeb, Dithane, Ridomil Gold MZ and Gavel) and metiram (Polyram) were to be cancelled with the exception of foliar applications to potatoes. Representatives from the Ontario Fruit and Vegetable Growers Association and the Canadian Horticulture Council met with PMRA to voice their concerns about the loss of these products and a new review process was agreed upon.

The decision for metiram could not be reversed for legal reasons. This means that as of June 2020, Polyram cannot be used on any crop except potatoes and the label will reflect that change.

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 recently announced that it will be cancelling the use of the group M3 chemicals mancozeb and metiram in a wide range of crops, including field tomatoes.

In 2020 products like Manzate, Penncozeb, Dithane and Polyram will no longer be available for sale and in 2021 use will be banned completely. This will ultimately have an effect on how we control diseases, including anthracnose, early blight and, most importantly, late blight. Although mancozeb is currently an important player in fungicide programs, tomato growers do have other options available.

For best control it is always good to start with preventative or protectant fungicides once environmental conditions are conducive to disease development and before symptoms appear. | READ MORE

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.

Venture L Herbicide was already labeled for use on a number of crops in Canada for control of several weeds.

These minor use projects were submitted by Agriculture & Agri-Food Canada, Pest Management Centre (AAFC-PMC) as a result of minor use priorities established by growers and extension personnel. | READ MORE
