VIDEO: Goss’s wilt bears watching for corn growers

The relatively new bacterial infection of corn has moved north from the U.S. Midwest in recent years

By
A corn disease that gained a foothold in Manitoba a few years ago is one to watch, according to a provincial crops specialist. Veronica Owusu, crop production extension specialist with Manitoba Agriculture out of Gimli, says agronomists and farmers should check for Goss’s wilt. The bacterial disease has moved north from the American Midwest and

Soybean cyst nematode in crosshairs for food-grade soybeans

Future varieties will resist diseases SCN and white mould

By
Soybean cyst nematode and white mould are bad news for Canadian soybean growers and, although both are more of an issue to the east, SCN has been creeping into Manitoba for the last five years. In 2021, Manitoba saw its first field with symptoms, although the first finding of the nematode dates back to 2019.

Clubroot ‘race profiling’ can help boost resistance in canola

Research team sets stage for next generation of canola resistance

By
Glacier FarmMedia – Racial profiling isn’t a term most people would want to be associated with. When it’s a disease like clubroot, however, it’s different. In the fight against the yield-stealing, soil-borne scourge of canola and other brassica plants, racial profiling is the ability to select varieties that resist not only clubroot in general, but
“We should continue breeding local varieties that are adapted to Manitoba and not rely on other entities.” – Daryl Domitruk, Manitoba Pulse and Soybean Growers.

Pulse Growers releases research cluster results

Insights will push forward root rot research, variety development

By
Results from a five-year cluster of research will advance work on issues like root rot and develop locally adapted pulse varieties, according to the Manitoba Pulse and Soybean Growers (MPSG). The group recently released the results of studies it co-funded through the Pulse Science Cluster. MPSG contributed just over $1.4 million to eight projects within

Crop diseases to watch for in 2023

Some pathogens are expected to be on the rise this coming year

By
The apparent transition into a wetter period means different diseases to watch out for, says David Kaminski, field crop pathologist with Manitoba Agriculture. Kaminski was speaking at the CropConnect conference in Winnipeg on February 15. Two crops dominate Manitoba’s agricultural landscape. Wheat and canola account for 70 per cent of the annual crop acres in

An inoculation against blackleg

University of Manitoba trial shows a less-virulent strain boosts canola’s natural defences

By
A new biological control strategy could be a game changer in the battle against blackleg in canola. The fungal infection that has a yield-destroying effect on canola crops was first discovered in Saskatchewan in 1975 and eventually spread across the country. Blackleg is the result of the interaction between two closely related fungal species, Leptosphaeria

VIDEO: Researchers brainstorm on potato vine removal

Labour is the biggest hurdle to the disease management practice

By
Researchers at the Canada-Manitoba Crop Diversification Centre (CMCDC) are looking for ideas that would lessen the labour of removing green potato vines in the fall. The practice is pitched as a control measure against pathogens such as black dot, verticillium wilt, early blight and other diseases that carry over in potato crop residue. Why it

Getting a leg up on blackleg

New research finds blackleg populations are more diverse in Manitoba

By
New genomic research from Agriculture and Agri-food Canada (AAFC) could give agronomists a leg up in the fight against blackleg in canola. Blackleg (Leptosphaeria maculans) is a severe fungal disease of canola plants, and with canola generating about one-quarter of all farm crop receipts in Canada, it is a serious threat to producers.
