Advancements in RNA interference (RNAi) technology could soon unlock new tools for managing canola pests and pathogens, such as sclerotinia and flea beetles. RNAi — ribonucleic acid interference — involves targeting specific RNA sequences in a disease or pest, rather than targeting entire proteins or enzymes, as is the case with current pesticides. It’s a… Read More
Canola and soybean growers will have a new fungicide option to help protect their crops from sclerotinia and white mould. Corteva Agriscience has launched Viatude, a fungicide that offers multiple modes of action for resistance management. It also contains a unique combination of two highly effective ingredients, including Corteva’s proprietary active, Onmira, the company says…. 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
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.

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
