It’s time for Day 6 of the virtual Ontario Diagnostic Days! This week we’ll look at effective sprayer applications with a focus on fungicides. We’ll call on Ontario researchers and extension specialists to tackle everything from identifying disease and selecting control products to evaluating spray coverage and choosing the right application method. The line-up includes… 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
Farmers across Canada will have five new fungicides in their disease management toolbox in 2020. This week, Syngenta Canada rolled out Miravis, a new fungicide umbrella brand that will offer five new products growers can use to fight disease in a range of crops. In this video, Eric Phillips, Syngenta Canada’s fungicides and insecticides product… 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
Ontario corn growers will have plenty of variables to consider as they plan fungicide applications in the weeks ahead. An extended five-week planting season has produced huge variability in the crop, with current maturity ranging from the two- to eight-leaf stage depending on where you farm in the province. In this episode of RealAgriculture’s Corn… Read More
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
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
If above average moisture continues through June, growers should start scouting early for northern corn leaf blight (NCLB). Rob Miller, BASF’s technical development manager for eastern Canada, says NCLB can appear as early as the 8-10 leaf stage in a wet season. Lesions appear on the lower leaves and move upwards, as the infection often… Read More
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
