Soybean School: New coalition tackles growing nematode resistance

Soybean cyst nematode (SCN) is the crop’s number one yield-robbing pest, and the problem is only going to get worse as the pest continues to breakdown the defence provided by SCN-resistant soybean varieties. It really is a case of the pest becoming “resistant to the resistance,” says Iowa State nematologist Greg Tylka. About 95 percent… Read more »

Soybean School: Make resistance a priority when selecting varieties

Next time you chose a soybean variety, don’t just consider yield trials. Be sure to take a close look at disease trials; they help determine whether the yield potential of the variety you select will become reality in your field, says OMAFRA plant pathologist Albert Tenuta. In this episode of the Soybean School, we catch up… Read more »

Soybean School: Rotating resistant varieties key to controlling SCN

Soybean cyst nematodes have been stealing yield in Ontario fields for more than 20 years. SCN-resistant varieties are a key tool to help defend against the invading pest, but growers need to ensure they’re not putting the effectiveness of these resistant varieties at risk. In this episode of RealAgriculture Soybean School, OMAFRA plant pathologist Albert… Read more »

Soybean School: Putting the pinch on cyst nematode

Soybean cyst nematode (SCN) continues to spread across Ontario. The yield-robbing pest was first discovered in the southwest of the province in 1988 and continues to expand north and eastward. OMAFRA plant pathologist Albert Tenuta encourages all growers to take a close look at their soybean fields to determine whether the pest is present. SCN… Read more »

Soybean School: Reducing residue could fend off sudden death

When it comes to integrated disease management, experts have always considered corn a non-host for diseases like sudden death syndrome (SDS) in soybeans. But that perception is changing says OMAFRA field pathologist Albert Tenuta. In this episode of RealAgriculture Soybean School, Tenuta says there is growing evidence that corn residue can harbour or allow the… Read more »

Corn School: Evaluating late-season northern corn leaf blight control

With late planting and slow maturity, much of Ontario’s corn crop may be in for a challenge as leaf diseases arrive in fields across the province. In this episode of RealAgriculture Corn School, we catch up with Ontario Ministry of Agriculture, Rood and Rural Affairs (OMAFRA) field pathologist Albert Tenuta in his leaf disease nursery… Read more »

Soybean School: No payback for white mould revenge spraying

White mould is showing up in soybean fields across Ontario, especially in areas that have consistently seen wet weather and moderate temperatures throughout the summer. In this episode of RealAgriculture Soybean School, OMAFRA plant pathologist Albert Tenuta explains that the fungicide timing for optimal control of white mould is as flowers emerge at the R1… Read more »

Corn School: Could 2017 be another vomitoxin year?

A late-maturing crop, difficult environmental conditions, significant insect pressure and potential for late-season leaf disease…although too early to tell – this growing list of factors could lead to another year of high vomitoxin levels in the Ontario corn crop. In this episode of RealAgriculture Corn School, OMAFRA plant pathologist Albert Tenuta takes a look at the… Read more »

Risk versus reward: thinking critically about cover crops

It’s hard to find a farmer these days who doesn’t see some of the benefits cover crops can bring to their operation. From reduced soil erosion to improved soil structure, nutrient recycling, moisture retention and much more – the list of benefits is long and impressive. But how much is too much? Where and when… Read more »

Corn School: Leaf Blight Defence Starts With Genetics

Choosing the right genetics is the most important decision growers make when tackling leaf diseases such as northern corn leaf blight (NCLB). Fungicides applied in-season can provide both curative and preventative benefits, but the battle to fend off yield-robbing leaf diseases starts with your seed choice explains, OMAFRA field pathologist Albert Tenuta. In this episode… Read more »

Soybean School: Genetics Lead Fight Against Sudden Death Syndrome

2016 was a good year to grow soybean varieties with strong genetic resistance to sudden death syndrome (SDS). Ontario Ministry of Agriculture, Food, and Rural Affairs plant pathologist Albert Tenuta explains that this season’s cool, wet early growing conditions, which then gave way to drought in many regions of Ontario, helped the disease pack a… Read more »

Soybean School: Why Are My Soybeans Turning Yellow?

That’s a question many growers ask when they see parts of their soybean fields prematurely turning yellow in August and early September. In this episode of Real Agriculture Soybean School, OMAFRA’s Albert Tenuta and University of Guelph researcher Dave Hooker team up to answer the question and provide management tips. When his phone rings, Tenuta… Read more »

Corn School: Protecting the ‘Factory’ Best Defence Against Leaf Disease

Leaf disease can strike anywhere on a corn plant, but where does it take the biggest bite out of corn yield? In this Real Agriculture Corn School episode, OMAFRA plant pathologist Albert Tenuta explains that diseases such as northern corn leaf blight (NCLB) and grey leaf spot typically take root in field residue where pathogens… Read more »

Taking the Risk Out of Cover Crops

Cover crops have long been touted for their ability to help maintain soil health, control erosion, reduce nutrient loss and improve soil fertility. But could they put grain and oilseed crops at risk by playing host to disease and pests? That’s a question OMAFRA field pathologist Albert Tenuta is trying to answer. In this video,… Read more »

New Soybean Seed Treatment Takes Aim at SDS and SCN

Soybean growers have a new tool in their fight to manage the impact of sudden death syndrome (SDS) and soybean cyst nematode (SCN). Earlier this month, Bayer CropScience received registration for Ilevo/Votivo, a new soybean seed treatment. At its recent Dead Weeds Tour, Bayer’s D&L Manager Luc Bourgeois told growers it will be the first… Read more »
