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
Health Canada’s Pest Management Regulatory Agency (PMRA) has released its decision on the re-evaluation of mancozeb and will continue registration only for foliar application to potato crops.“All other uses of mancozeb are being cancelled due to unacceptable risks to human health and will be removed from the labels,” states a summary of the decision.Foliar application on potatoes has been limited to 10 applications per year at a maximum application rate of 1.68 kg of active ingredient per hectare with a seven-day interval between applications and a one-day pre-harvest interval using aerial or ground spray only.Product labels must be changed within 24 months. Registration of products being cancelled as a result of the review will expire 36 months after the release of the decision. Chemical companies have 12 months and retailers 24 months to sell old product.
Syngenta Canada Inc., is pleased to announce the registration of Revus fungicide as a potato seed treatment for the suppression of pink rot and control of seed‑borne late blight in potatoes.Pink rot is a devastating, soil-borne disease caused by the pathogen Phytophthora erythroseptica that thrives in wet, poorly drained soils. Infection typically takes place pre-harvest, as the pathogen enters tubers through the stem end and lenticels.Tubers infected with pink rot will often decay during harvest and handling, which allows the pathogen to spread quickly from infected tubers to healthy tubers while in storage.“Every field has the potential for pink rot,” says Brady Code, eastern technical lead, with Syngenta Canada. “It takes a very small number of infected tubers going over harvest equipment or getting by on the belt to put an entire season of work in jeopardy and leave growers with far fewer healthy potatoes to ship.”Revus contains the active ingredient mandipropamid (Group 40) and works by protecting the daughter tubers from becoming infected with pink rot.“Growers can use Revus as part of an integrated approach to target fields where they’ve had pink rot issues in previous seasons, on their more susceptible varieties, and in tandem with other in-furrow and post-harvest fungicides,” explains Shaun Vey, Seedcare and Inoculants product lead with Syngenta Canada.Vey adds that Revus also provides control of seed-borne late blight (Phytophthora infestans). Syngenta research demonstrates that potatoes treated with Revus for seed-borne late blight have nearly perfect emergence, while untreated seed potatoes infected with late blight have a 20 to 30 per cent reduction in emergence.“Seed-borne late blight can have a big impact on emergence over time,” explains Vey. “When used as a seed treatment, Revus can help prevent seed piece decay and the spread of disease spores from seed piece to seed piece.”Revus is applied at 5.9-11.8 mL per cwt of seed (13-26 mL/100 kg of seed).Following a seed treatment application of Revus fungicide, the first foliar fungicide application should be a product that does not contain a Group 40 active ingredient.Maximum Residue Limits (MRLs) for mandipropamid, have been established for markets including Canada, the United States, Japan, and South Korea, in support of the seed treatment use pattern.For more information about Revus potato seed treatment, please visit Syngenta.ca; contact your local Syngenta Representative or our Customer Interaction Centre at 1‑87‑SYNGENTA (1‑877‑964‑3682).

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. For more information about Orondis Ultra, visit Syngenta.ca, contact your local Syngenta representative or call 877-964-3682.
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.

If you were going to tank mix chemical pesticides, you would of course read the label to check for compatibility before mixing products. The same concept applies when using living organisms for pest control. Whether you are using parasitoid wasps, predatory mites, microorganisms, or nematodes, you need to know whether your biocontrols are compatible with each other and any other pest management products you plan to use. For example, a biocontrol fungus might be killed if you tank mix it with (or apply it just before) a chemical fungicide. Insecticides (whether or not they are biological) could be harmful to natural enemy insects and mites. Even some beneficial insects are not compatible with each other because they may eat each other instead of (or in addition to) the pest. | READ MORE
Corteva Agriscience, Agriculture Division of DowDuPont, recently announced that the Pest Management Regulatory Agency (PMRA) in Canada has granted Dow AgroSciences upgraded approval for Closer Insecticide use to actively control Woolly apple aphid in pome fruit crops.“Canadian apple growers who have used Closer in the past know of its exceptional speed and ability to knockdown aphids.
