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 »

Wheat Pete’s Word, July 23: Diseased Wheat, A Corn Alert and White Mould Timing(s)

Wheat harvest is underway in southern parts of Ontario, with yields ranging anywhere from an ugly-and-diseased 40 bushels an acre to 110 bushels in areas south of London, as Real Agriculture agronomist Peter Johnson shares leading off his update this week. What’s there to be learned from all the fusarium in wheat this year? It’s that… Read more »

Corn School: Rating & Recording Hybrid Susceptibility to Northern Corn Leaf Blight

We’re approaching a critical stage for corn — tasseling — and weather conditions in some areas are conducive to high disease development. Recently in the Corn School, we’ve talked prioritizing fields for a fungicide application and where and how to scout for leaf disease in corn, but did you know that there’s another factor at… Read more »

Corn School: Top Tips for Corn Disease Scouting

Several factors converge to increase the threat of diseases on a corn crop, from the history of a disease in the field, to the amount of residue, to the weather. Unfortunately, several corn diseases are carried by wind and can end up in your field whether you practice good rotation practices or not. Related: How… Read more »

Corn School: How to Triage Your Fields for Fungicide Application Timing

You have several corn fields and only one of you — how do you prioritize which field gets fungicide first? 2015 is shaping up to likely be a high disease pressure year, says Albert Tenuta, field crop plant pathologist with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), and a little planning now… Read more »

Corn School: How Well Does Your Hybrid Stand up to Northern Corn Leaf Blight?

If you’ve noticed increasing levels of northern corn leaf blight in some of your fields, it could be that the hybrids you’re planting don’t have the right gene to resist infection. That’s because the pathogen has evolved to bypass some of the older sources of resistance, says Albert Tenuta, field crop pathologist with the Ontario… Read more »

Soybean School: To Till or Not to Till for White Mould Management?

It’s a disease that affects a number of significant crops in Canada, including vegetables, pulses, canola and even some forage species. And last year, some farmers saw particularly high levels of white mould in soybean crops across Ontario. Sclerotinia sclerotiorum, or white mold, makes its mark on plants in lesions that appear water-soaked; white, fluffy mycelium;… Read more »

Agronomy Geeks Ontario — Ep. 11: Fending off Fungicide Resistance, Plus New Threats to Watch For

The disease pressure landscape changes as the season progresses and from year to year, but there are always the endemic threats that farmers have to manage for. Part of the disease scouting process includes knowing what to look for, including some new or rare pests that could be making their way into your growing region…. Read more »

Soybean School: The Value of Seed Treatments

Planting in to cool and especially cool and wet soils is not ideal for soybeans. But that description applies to most planting conditions in Ontario and perhaps most of Canada. Because of this reality, fungicide seed treatments are an invaluable tool in the establishment of healthy, vigorous, soybean stands. Albert Tenuta, provincial field crop pathologist… Read more »

Soybean School: Scouting for Soybean Cyst Nematode

Damage from soybean cyst nematode can be minor, but once this pest is established in a field, it’s there for good. Since being confirmed in Ontario about 15 years ago, the nematode moved throughout much of the soybean growing region. Knowing the nematode pressure level in your fields is essential to minimizing damage through the… Read more »
