First found in 2014 in Manitoba, verticillium stripe has become a more common disease found in canola. In parts of Manitoba, the season started with an excess of moisture and was hot, which led to the perfect breeding ground for the disease. Which is why it was the heaviest year on record in Western Canada… Read More

There are so many insects in the world that most of them likely haven’t been described yet. From some of the more common insects, such as the flea beetle, to a lesser-known such as a the beet webworm, this episode of The Agronomists tackles as much as we can in an hours’ time. Host Lyndsey… Read More
When it comes to weed control, we can’t always wait for the next thing in the pipeline, we need to manage what we have — which sometimes means getting creative. For this edition of the Agronomists, host Lyndsey Smith is joined by Jeanette Gaultier of BASF, and Rob Bahry of ADAMA Canada, to discuss clever… Read More
What’s the number one disease problem in edible beans in Ontario? That’s a question University of Guelph associate professor Chris Gillard asked in a recent grower survey and the answer wasn’t surprising, says the edible bean researcher. Sixty-seven percent of growers named white mould as their biggest disease problem, and an even higher 75 percent… Read More
It appears in 2022 that Ontario growers have little to worry about when it comes to corn ear moulds such as gibberella contributing to elevated levels of mycotoxins in the corn crop. In late October, the annual Ontario corn ear mould and deoxynivalenol (DON) mycotoxin survey found 98 percent of samples tested low — less… Read More
Higher yields are always a top priority for plant breeders developing new crop varieties, but yield itself is the result of a combination of different factors, including resistance to disease threats, maturity timing, and harvestability. These characteristics are all taken into consideration when screening and developing new edible bean varieties, explains Anfu Hou, bean breeder… Read More
Every field tells a story, and not just through the yield monitor. From final plant stand figures, to disease pressures, to weed spectrums and control windows, harvest and post-harvest scouting can offer so much information about what to do next year or the next time a field sees this crop again. To dive in to… Read More
Multimodes of action in one product is the name of the game for many new crop protection products, and BASF’s new line up for 2023 holds to that. Building on last year’s launch of Veltyma fungicide, growers in Ontario can look for Veltyma DLX in 2023 for protection from northern corn leaf blight, tar spot,… Read More
More and more cases of waterhemp are being discovered, and last year, Manitoba saw its first confirmed finding of Palmer amaranth. As many producers are painfully aware — both weeds can be extra difficult to control, and herbicide resistance has only increased. Manitoba’s neighbour to the south is no stranger to either weed, with the… Read More
Iowa State University has been collecting data and building a scouting app that can identify about 2,000 insect pests at varying stages. “This app can not only identify the adult stage insect, but it can also identify other various stages, like a nymph or caterpillar,” says Dr. Arti Singh, assistant professor in the department of… Read More
As soybean cyst nematode (SCN) wriggles its way north, Western Canadian farmers can look to southern neighbours for advice on managing this pest. Sam Markell, extension plant pathologist with North Dakota State University (NDSU), says that late in the growing season is an excellent time to test for the pest. A core sample taken six… Read More
It’s time for Day 2 of Ontario Diagnostic Days! The annual Ontario crop diagnostic days were back in the field on July 20 and 21, 2022, but only at Ridgetown campus University of Guelph. Not everyone could attend these two field days, so the organizing committees of these highly successful in-field education and learning events are again… Read More
First found in Canada in southern Alberta in the 1990s, the pea leaf weevil is continuing to expand its territory to the east. The invasive pest whose larvae feed on the rhizobia in nitrogen-fixing root nodules has since spread across most of the pea-growing areas of Alberta and Saskatchewan. It was first detected in Manitoba,… Read More
On Wednesdays we listen to Wheat Pete’s Word. Welcome back to another episode as we close out August and look forward to September. On today’s show, Peter ‘Wheat Pete’ Johnson dives into some of the yield numbers coming out of Ontario, which in most areas, are turning out better than expected. He also goes over… Read More
Wednesdays are for Wheat Pete’s Word! This late August episode of the Word features some yield estimates with a discussion on whether to over- or under-estimate, a first look at fungicide pay-back on wheat, the mightiness of rye in rotation, and why waterhemp is a menace. Have a question you’d like Johnson to address or… Read More
