Sclerotinia is one of the most challenging diseases for growers to manage in canola, and in soybeans, where it appears in the form of white mould. In both crops, field history and moisture are two key drivers of the disease. Hit play and watch/listen to this episode on sclerotinia and white mould featuring Chris Manchur… Read More

Sclerotinia is predictably unpredictable. Always lurking but not always a problem, so making the call to protect canola flowers can be a tough one in dry years. To talk sclerotinia (also known as white mould of soybean and dry beans) prevention and management, special guest host Kelvin Heppner is joined by Jeanette Gaultier of BASF,… Read More

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
