Should you go ground or air? That’s the question many growers struggle with as they try to determine the best method of applying disease-fighting fungicide to their growing corn crops. On this episode of RealAgriculture Corn School we tackle that question with two of North America’s leading plant pathologists — University of Kentucky’s Kiersten Wise… Read More
First there were strobilurins, then came triazoles, and now we have succinate dehydrogenase inhibitors or SDHIs. That can be a bit of tongue twister, but it also adds up to three classes of fungicides and multiple modes of action that more growers are stacking up to bring stronger disease protection to their cornfields. That’s the… Read More
The good news is tar spot — a new corn leaf disease — has yet to be found in Ontario cornfields. The bad news is it’s only a matter of time before the yield robber is confirmed in the province, says Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta. On this episode… Read More
As growers actively manage herbicide-resistant weeds on their farms, many are also looking at how to secure future effectiveness of other crop protection tools, including fungicides and insecticides. In this first episode of a new season of RealAgriculture’s Resistance Management School, we take a look at the current state of fungicide resistance in field crops… Read More
From the two brothers working on identifying the disease across provinces, to the sister-like relationship between soybean cyst nematode (SCN) and sudden death syndrome, it’s a family affair when talking SCN. Albert Tenuta, plant pathologist for the Ontario Ministry of Agriculture, Food and Rural Affairs, joins RealAgriculture’s Bern Tobin for this episode of the Soybean… Read More
Testing for DON in Ontario’s 2018 corn crop was an incredibly frustrating process for growers. With gibberella ear rot infecting a wide swath of corn in the province, many growers were exasperated when samples from the same load of corn taken from a field would show wide variation in DON levels — sometimes from 3… Read More
Challenging Ontario planting conditions may follow the corn crop through the entire season and cause 2019 harvest disease headaches for growers. That’s the message Ontario Ministry of Agriculture, Food and Rural Affairs’s plant pathologist Albert Tenuta shared with growers attending a Huron Tractor combine clinic last week at company headquarters at Exeter, Ont. With corn… Read More
Tuesday’s RealAg Radio is all about pests and policy — but perhaps not the pests you commonly think of. On this episode, host Lyndsey Smith speaks with: Jessika Guse, with the news; Sylvain Charlebois, about the national food policy; Ryan Brook, about wild hogs in Saskatchewan; and, Bern Tobin asks Albert Tenuta about what farmers… Read More
It’s been an unusual year across Ontario and growers could see more of the same as the soybean crop emerges from cool, wet soils, says Albert Tenuta, plant pathologist with the Ontario Ministry of Agriculture Food and Rural Affairs. Tenuta believes the backward spring, which has pushed soybean planting to late June across the province,… Read More
From an environmental standpoint, Ontario experienced a perfect storm in 2018 that produced an epidemic of gibberella ear rot in corn and resulting unprecedented DON levels. Ontario Ministry of Agriculture, Food and Rural Affairs field crop plant pathologist Albert Tenuta compares the conditions that created the classic silk channel infection in corn hybrids to what… Read More
RealAg Radio host Shaun Haney, opens agronomic Monday with news about a new app from Agriculture and Agri-Food Canada (AAFC). Saskatchewan field editor Dale Leftwich speaks to field crop entomologist Tyler Wist, from AAFC, about their new Cereal Aphid Manager (CAM) app. It’s the first app AAFC has ever had and features pictures both of the… Read More
Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta is gearing up for his annual pre-harvest corn disease survey, and he’s optimistic leaf disease will not have a significant impact on the 2018 corn crop. Some growers have raised concerns that a rainy late July and August could lead to a flood… Read More
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
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 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
