Planting across Ontario is nearing completion in many regions, but excessive rain continues to stall progress in some areas, leaving farmers to contemplate switching intended corn acres to soybeans. It’s a decision that has significant cropping implications, says RealAgriculture agronomist Peter Johnson, and he wants growers to look at all the potential impacts before making… Read More

In recent years, many corn growers in Ontario have wrestled with gibberella ear rot in the crop and the high levels of deoxynivalenol (DON) levels it can produce in the grain. It’s made for stressful harvest seasons, especially in 2018 when mycotoxins produced by the gibberella fungus in some fields climbed well above safe feeding… Read More

Tar spot was a little late arriving in Ontario cornfields in 2023, but the leaf disease ramped up post tasseling, and with an extended fall, took a late-season bite out of grain yields in southwestern areas of the province. Growers who sprayed fungicides to defend their crop against disease were rewarded with higher yields, reports… Read More

Tar spot leaf disease has been a little tardy in 2023, but the later-arriving yield robber is still having an impact on the Ontario corn crop. Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist Albert Tenuta says a dry start to the growing year meant tar spot arrived a little late in 2023… Read More

When heavy summer rains arrive, Albert Tenuta’s phone starts to ring. The Ontario Ministry of Agriculture, Food and Rural Affairs plant pathologist started hearing from growers across the province in late June as soil-borne disease moved into many soybean fields after a series of pounding rain events. When soybeans get wet feet in early summer,… Read More

Soybeans don’t like wet feet, and when rain is plentiful in June and July, saturated soils typically lead to an increase in fungal seedling diseases. Four of the most common culprits are pythium and phytophthora root rots as well as rhizoctonia and fusarium. On this episode of the RealAgriculture Soybean School, Ontario Ministry of Agriculture,… Read More

Wet, humid conditions can cause corn diseases to advance quickly. The usual suspects are always a concern: Northern corn leaf blight, gibberella ear rot, and more, but a new-to-Ontario disease, tar spot, has been harder to predict when it comes to threat level. In 2022, early indications showed the disease was present but a dry… Read More

Thanks for tuning in to this Agronomic Monday edition of RealAg Radio with host Shaun Haney. We will hear from Peter Johnson of RealAgriculture on nitrogen, ultra early seeding, sunshine, and much more! Then, we’ll hear from Albert Tenuta, plant pathologist with Ontario Ministry of Agriculture Food and Rural Affairs, on tar spot risk in… Read More

The Christmas holidays are here! What better way to spend the time than catching some of the 30 Corn School episodes RealAgriculture published in 2022? We kicked off the season in January with Purdue University agronomy professor Dr. Tony Vyn who tackled the question: where does yield come from? Vyn notes that hybrid research over… Read More

Fungicides are a key tool in the tar spot management toolbox. But what’s the best time for growers to apply a fungicide to get optimal control of the disease and the best return on their crop protection investment? On this episode of the RealAgriculture Corn School we catch up with Ontario Ministry of Agriculture, Food… Read More

It’s time for the second Ontario Diagnostic Day episode of The Agronomists! For this episode, guest host Bernard Tobin (with a great hat) guides guests Horst Bohner and Albert Tenuta, both with the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) on an exploration of soybean seed quality and corn leaf diseases. This episode… Read More
