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

Syngenta has announced plans to bring the first three-mode-of-action foliar fungicide to farmers in Eastern Canada this spring. Trivapro features three active ingredients, including one new active — azoxystrobin (Quadris – Group 11), propiconazole (Tilt – Group 3), and benzovindiflupyr (Group 7 SDHI), known as Solatenol. Solatenol was approved for use on corn, soybeans and… Read More
The hay crop, white mould, norther corn leaf blight, and nitrogen management tools are all high on farmers’ radars this week as we head into the first full week of July. To kick off this week’s Wheat Pete’s Word, Peter Johnson, RealAgriculture agronomist, has a word of caution about the hay crop. Wet ground is… Read More
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
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
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
Just like there are many strains of the common cold and the flu, plant diseases can be caused by “races” of the same pathogen. Northern corn leaf blight is one disease that has at least 13 strains — four to six of which affect corn crops in Ontario. In this episode of the Agronomy Geeks… Read More
