Soybean cyst nematode survey a valued benchmark opportunity

Project will target more than SCN

By
Reading Time: 3 minutes The word nematode is often linked to soybean cyst nematode (SCN), and with good reason. In North America, SCN accounts for annual losses of more than $1 billion and up to $50 million in Ontario. A survey of field and horticultural crops across the province seeks to update provincial nematode distribution maps and establish baseline […] Read more

Pest Patrol: Soybean cyst nematode (SCN) and sudden death syndrome (SDS)

#PestPatrol with Albert Tenuta, OMAFRA

By
Reading Time: 2 minutes The dry conditions in 2020 have been favourable for soybean cyst nematode (SCN) infection. A reminder that you can look for SCN by digging up plants with a shovel and gently removing soil and examining roots for the presence of the small white to yellow cysts (Figure 1 below). Cysts are considerably smaller (1 mm) […] Read more
Sudden death syndrome is expected to worsen in southwestern Ontario soybeans and root rot could also be a serious concern this year if the conditions at planting time are wet.

Soybean and corn disease threats in Eastern Canada

Growers will need to use all their experience, best management practices and new tools to successfully combat disease in 2020

By
Reading Time: 4 minutes Another crop season is upon us and certain disease threats stand out in soybeans and corn in Eastern Canada. “SDS (sudden death syndrome) is expected to worsen in southwestern Ontario soybeans and root rot could be a serious concern this year if the conditions at planting time are wet,” notes Dr. Owen Wally, research scientist […] Read more
The 2018 growing season was bad for gibberella ear rot in many corn fields and it remains a challenge.

Disease outlook for the 2020 crop season

We can’t be sure which diseases will attack this year, but indications are that once they arrive, they’ll be here to stay

By
Reading Time: 7 minutes What will be the big disease concern this year? Will it be tar spot in corn, or frog-eye leaf spot in soybeans? Or will growers be facing more of the same, with soybean cyst nematode and northern corn leaf blight? Forecasting diseases is iffy at best. The truth is that most disease pathogens, once they […] Read more

Soybean cyst nematode isn’t getting better

The latest numbers confirm what we already feared

By
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

Are soybean diseases getting worse?

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

By
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

By
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

Soybean cyst nematode tough in dry beans too

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

By
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

By
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

By
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
