Soybeans were harder hit by sudden death syndrome in 2020 but late enough that it didn’t have much effect on yield.

Group 7 seed treatment protects against sudden death syndrome

Soybeans show more above and below ground biomass with the treatment

Reading Time: 2 minutes New fungicide seed treatment Saltro protects soybeans from sudden death syndrome and canola from airborne blackleg, new research indicates. The seed treatment, with the active ingredient Adepidyn, is a Group 7 fungicide belonging with the carboxamides. It works by moving through the plant’s water-conducting system and is taken into the cotyledons. Why it matters: New […] Read more

It’s important to look at the big picture when dealing with a quality and yield issue with forages before jumping to a fungicide for improvements.

Fungicides not always an answer in alfalfa

Spraying could make sense when conditions are right for fungal disease

Reading Time: 2 minutes Farmers must weigh many factors before applying fungicides to alfalfa, said Christine O’Reilly, forage and grazing specialist with the Ontario Ministry of Agriculture, Food and Rural Affairs. Why it matters: Farmers have found that there have been advantages to using fungicides in corn and with approved options, are now looking at alfalfa. O’Reilly says the […] Read more

Potato fungicide restrictions will lead to more expensive application options.

Fungicide reductions challenge potato growers

Spraying programs could double in cost in 2020

Reading Time: 3 minutes Regulatory changes by the Pest Management Regulatory Agency (PMRA) are limiting fungicide options for Ontario potato farmers. That means more cost and more chance of resistance, says Darin Gibson with Gaia Consulting Ltd. in Manitoba. He spoke on the topic at the 2020 Ontario Potato Conference held in Guelph March 5. Why it matters: The […] Read more

Syngenta launches five new fungicide products

Reading Time: 2 minutes Syngenta Canada recently launched Miravis, a lineup of five fungicide products designed to protect crops against several of the most destructive diseases facing Canadian farmers. Miravis fungicides are built with Adepidyn, a new Group 7 fungicide belonging to the carboxamide chemical class. Miravis fungicides are registered in Canada on multiple crops – including wheat, canola, […] Read more

Using a system called bee vectoring, the insects will deliver a fungus called Clonostachys rosea to prevent disease in a wide variety of crops.

Bees approved to deliver disease control

Ontario technology gets U.S. approval for bio-fungus delivery by bees

Reading Time: 3 minutes Glacier FarmMedia – Thirty years is a long time to wait. For John Sutton, the wait has been worth it because his novel idea from the late 1980s is finally coming to market. The United States Environmental Protection Agency recently approved a Canadian technology that uses bees to deliver a bio-control fungus that protects plants […] Read more


Ideal timing of ear rot fungicides can lower DON levels by 60 per cent. When silk is brown is too late.

Timing fungicide applications on corn crops essential

Delayed maturity of corn may put it into more favourable conditions for disease development

Reading Time: 3 minutes Delayed maturity in corn throughout the province from late planting into challenging soil conditions is causing corn maturity to move into more favourable conditions for many diseases. Albert Tenunta, OMAFRA’s field crops pathologist and Dave Hooker, an associate professor at the University of Guelph’s Ridgetown College, said at the recent Ridgetown-based Crop Diagnostic Days that […] Read more

Potato growers could be among the most affected by the re-evaluation of chlorothalonil.

Fungicide re-evaluation has growers looking for alternatives

PMRA re-evaluation of chlorothalonil will make it more difficult to use

Reading Time: 2 minutes Chlorothalonil, a broad-spectrum multi-site fungicide active ingredient found in horticulture fungicides, has been re-evaluated by the Pest Management Regulatory Agency (PMRA) for all uses within agriculture and turf. It is part of PMRA protocol to re-evaluate pesticide products every 15 years, or sooner, as science evolves and new information, methodologies and approaches become available to […] Read more

Pearce: Multiple modes of action an emerging reality for fungicides

Reading Time: 2 minutes As growers face more challenges from weeds, diseases and insects, many researchers, agronomists, advisers and farmers have shifted thinking from “control” of pests to “managing” them. Some of this trend is attributable to single-mode-of-action products and a reliance on one or two chemistries or technologies — but the adaptability of weed, disease and insect species […] Read more


U.S. study links bumblebee declines to fungicide use

Reading Time: 2 minutes A new look at the environmental factors around declining bumblebee populations and ranges points to a less-than-usual suspect: fungicides. “Insecticides work; they kill insects. Fungicides have been largely overlooked because they are not targeted for insects, but fungicides may not be quite as benign — toward bumblebees — as we once thought,” Scott McArt, assistant […] Read more
