Statistics from the SCN Coalition indicate SCN resistance in Ontario fields is breaking down.

Soybean cyst nematode isn’t getting better

The latest numbers confirm what we already feared

Reading Time: 4 minutes How much more can be said about soybean cyst nematode that hasn’t been discussed or debated already? It the worst yield-robbing disease in soybeans. Its key resistance gene, PI 88788, has broken down both in Canada and across the U.S. Midwest. Once it is in your soil, there is no means of removing it, so […] Read more

If soybean diseases are getting worse, these Japanese beetles are part of the story.

Are soybean diseases getting worse?

In spite of all the year-to-year variations, some worrying trends are developing

Reading Time: 5 minutes Ask a dozen farmers, advisors or industry reps to identify the worst soybean disease this year and it’s possible you’ll get a dozen different replies. Much of it depends on location, but there are concerns that some diseases are increasing in severity, if not frequency or geographic area. Some of the headline diseases of 15 […] Read more


Soybean cyst nematode confirmed in Manitoba

Reading Time: 2 minutes A damaging soybean pest that was expected to show up sooner or later in agricultural Manitoba has officially arrived. Crop surveys by University of Manitoba Ph.D. student Nazanin Ghavami with soil science professor Mario Tenuta and his students have turned up soybean cyst nematode at “extremely low” levels on soybean plant roots in one field […] Read more

Note the lack of visual SCN symptoms in these black beans despite field tests showing over 10,000 eggs per 100 cm3 of soil.

Soybean cyst nematode tough in dry beans too

The pest can be especially devastating in certain classes of edible beans

Reading Time: 6 minutes It’s a case of “something old, something new” for growers with edible beans. Soybean cyst nematode (SCN) is now a threat to producers with cranberry beans, white beans, kidneys and adzukis. Nematodes have been affecting soybean production in parts of Ontario since the late 1980s, and now it appears they have the capacity to weaken […] Read more


The impact of soybean cyst nematode on dry beans depends on the market class and potentially the specific variety.

Pest Patrol: Soybean cyst nematode in edible beans

#PestPatrol with Mike Cowbrough, OMAFRA

Reading Time: 2 minutes Have you ever had a dry bean crop that looked healthy but resulted in disappointing yields? Have you seen stunted or yellowing patches, but could not identify the cause? If so, you may want to look for soybean cyst nematode (SCN). Researchers in Ontario and the U.S. have shown that SCN is not just a […] Read more

New in IP soybean varieties

The market continues to follow the lead built by traited soybeans

Reading Time: 3 minutes The 2017 growing season has yielded an interesting trend which few seem to be aware of. Acres planted to soybeans in Canada reached a new high for this year at 7.3 million, an increase of 33.2 per cent from 2016. Those numbers from Statistics Canada have been something of a surprise for some, especially considering […] Read more


First soy seed treatment cleared against SDS

Reading Time: 2 minutes A Bayer CropScience fungicide is being pressed into service against sudden death syndrome (SDS) in Canadian soybeans. Bayer on Monday launched a new soybean seed treatment dubbed ILeVO, a suspension containing its Group 7 fungicide fluopyram at a rate of 600 grams per litre. ILeVO will be the first soybean seed treatment registered for use […] Read more

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

Stinkweed with the “penny-shaped” seed pods in a field of wheat.

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
