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

White mould of soybeans, dry beans and sunflowers is the same disease as sclerotinia of canola and sunflowers. What’s more, it’s a disease that can infect a multitude of broadleaf weeds. The endemic nature and soil survivability of the pathogen make it a tough disease to keep on top of. To tackle management of this… Read More
The decision whether to spray a fungicide for sclerotinia stem rot always comes back to the disease triangle — a susceptible host, the presence of the pathogen, and a favourable environment — and many canola-growing areas currently have all three. Under “favourable environment,” sclerotinia requires moist soil conditions to germinate. The last few years have… Read More
It’s been dry in parts of Western Canada heading into canola flowering, but has it been dry enough to hold off on spraying for sclerotinia? That’s a question many growers and agronomists in drought-affected areas have been asking themselves over the last week or two. There are really two basic factors to consider in the… Read More
Bayer Crop Science Canada is launching Proline GOLD, a new product for sclerotinia control in canola. Proline GOLD offers protection against sclerotinia in canola by combining two active ingredients, prothioconazole and the new active fluopyram. The other sclerotinia product from Bayer, Proline, contains only prothioconazole. “As one of canola’s most dangerous diseases, sclerotinia can severely… Read More

Every once in a while a group with a real passion for something get a chance to get together and talk about what they care about. If you get to be in room with with them, you can’t help but feel the energy and, most likely, learn something. The Western Forum on Pest Management (WFPM)… Read More
Each July canola growers are faced with the difficult question, “Should I or shouldn’t I spray for sclerotinia?” In the more humid parts of Western Canada, sclerotinia is a huge yield robber. It usually strikes on the years when the canola crop has its greatest yield potential, but spraying is expensive and proper timing can… Read More
Fungicide can be added to the list of crop inputs farmers can selectively apply using precision agriculture tools, targeting relevant areas within a field while avoiding patches where treatment isn’t justified. Bayer Digital Farming launched Zone Spray on Friday. It’s a program within the company’s Field Manager platform that creates prescription maps for fungicide in… Read More
When you see the stem rot in the field, it’s too late. And that’s just one of the reasons why managing sclerotinia is a challenge, as exerienced in 2016, a severe year for the disease in canola fields in Western Canada. In this Canola School episode, we talk to Michael Harding, plant pathologist with Alberta… Read More
Canola seed companies are releasing more varieties with claims they have reduced susceptibility to sclerotinia, but how do they determine those ratings? Coming off a season with high sclerotinia pressure, what does it mean if a variety is labelled as ‘partially resistant’? In 2011, the Western Canadian Canola/Rapeseed Recommending Committee started searching for a test that… Read More
Round one of fungicide application is done, but it’s starting to wear off and conditions are still conducive for disease. Knowing what your peas and/or lentils are worth this year, do you take the sprayer out or hire a plane for a second fungicide application? It’s a scenario growers in parts of Western Canada are finding… Read More
While sunflowers often pencil out well, concerns about quality and yield risk at the end of the year are all-too-common when it comes to growing them. “It’s a high value crop and if you treat it that way, it’s going to pay,” says Troy Turner, agronomist for the National Sunflower Association of Canada, in the… Read More

In this Pulse School episode, Shannon Chant of Saskatchewan’s Ministry of Agriculture shares her top five tips for a good (or even great) lentil crop: 5 Tips for a Great Lentil Crop Good quality seed — Of course it… Read More
While you’re in the field checking canola to see if it’s ready to be cut, or perhaps already swathing or harvesting it, it’s also a good time to assess the toll disease took on your crop. Sclerotinia, blackleg and clubroot can all cause premature ripening, as disease symptoms become more obvious at the end of the season,… Read More
