They are tiny world travellers and Manitoba’s Red River Valley could be  the next stop on the soybean cyst nematode’s global tour

By Shannon VanRaes August 11, 2015

In the middle of the Ian N. Morrison research farm near Carman, an unlikely scene is unfolding as farmers and agronomists crowd around what looks like an old jam jar. “Careful, we don’t want this to break,” Mario Tenuta stresses, with a bit of a chuckle. But what’s inside the tightly sealed jar is no

CFIA says reporting suspected verticillium wilt helps the farmer and Canada

How the yield-robbing disease is handled long term will depend on how widespread it is,  which CFIA will determine with a survey later this year

By Allan Dawson April 1, 2015

Canola growers should avoid the temptation to “shoot, shovel and shut up” rather than report suspected cases of verticillium longisporum, says the Canadian Food Inspection Agency.

By Shannon VanRaes February 5, 2015

Disease a North American first

Where it came from isn’t as important as how it will be contained when it comes to verticillium wilt in canola

By Reuters, Shannon VanRaes January 15, 2015

Manitoba prides itself on welcoming newcomers, but the canola sector won’t be rolling out the welcome mat for this one — verticillium longisporum. The disease was discovered in a Manitoba canola field late last fall and visually identified at Manitoba Agriculture’s Crop Diagnostic Centre. That determination was later confirmed by molecular analysis at the National
