Keeping the soybean cyst nematode at bay

Keeping the soybean cyst nematode at bay

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

Reading Time: 4 minutes In the middle of the Ian N. Morrison research farm near Carman, Man., 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 […] Read more

Growers are urged to be more diligent in digging up soybean plants to visually determine the presence of SCN.

Soybean cyst nematode frustration

Nematodes continue to rob farmers and frustrate agronomists, but a new biological seed treatment may soon help

Reading Time: 7 minutes It almost plays like a riddle. First are these clues: first confirmed here in 1988; called a disease by some and a pest by others; often ignored until it’s too late; and, impossible to eradicate. Of course, there’s another clue which should be a dead giveaway. It steals more bushels than any other soybean threat […] Read more

Pest Patrol: Do weeds support growth of disease?

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 2 minutes I have been asked whether it is true that some weeds can increase the prevalence of certain diseases. Yes, it is true, which is why it can be especially important to control these species. Henbit, purple deadnettle and stinkweed (field pennycress) are alternate hosts for soybean cyst nematode (SCN) and should be controlled. A study […] Read more

Disease risk for soybeans high

Soybean Guide: With so many rotations thrown out of sync, extra disease vigilance is essential for 2015

Reading Time: 8 minutes There’s only one word to describe the outlook for soybeans in 2015. It’s “more.” With a reasonable spring, Eastern Canada’s soybean crop may hit an amazing 3.25 million acres. But acreage isn’t the only number that may be up. We’re also likely to see more fields with second-year and some with third-year soybeans. Then, if […] Read more


A soybean emerges from the soil in its early stage of development.

Soybeans fight to reach full potential against cyst nematode

A growing problem with sudden death syndrome is causing concern for Ontario soybean growers, but one plant pathologist says it’s a manageable concern

Reading Time: 7 minutes It’s an in-field whodunnit — a burgeoning crop disease that closely resembles other better-known problems, but is its own unique culprit, with its own unique symptoms, development and costs. The first symptoms are a widespread mottling and crinkling of leaves on soybean plants, usually coming after the start of flowering, though in rare cases symptoms […] Read more

soybean root infected by cyst nematode

Extensive SCN survey shows numbers still climb

The collaborative study continues to identify 
heavier infestations and more spread of the disease

Reading Time: 4 minutes Soybean cyst nematode was first identified in Ontario in 1988, and since then it has spread through much of the province. Despite nearly three decades of experience with this pest, Ontario is still a relative newcomer compared to places like Tennessee, with its history dating back to the 1950s. Other states such as Illinois and […] Read more
