Tar spot was first confirmed in Ontario at Ridgetown in the southwest corner of the province in 2020. Since then, the corn leaf disease has spread across Ontario, pushing east past Toronto and into Quebec. Many Ontario farmers experienced the yield robber in their fields for the first time in 2024 and the disease is… Read More

Wheat Pete wishes he didn’t have to talk about safety but he has to. More farmers are telling him that they’ve had draw pins stolen. Make sure you do a circle check and check the pins before moving wagons — you could save a life. Farmers also have to stay safe around grain bins. Pete… Read More
Fall conditions in Ontario are quite dry and that has some growers wondering if the wheat is OK. More farmers are also perhaps getting a little carried away with fall field work, because, well, there’s time and dry conditions to do some! To discuss what’s going on with the wheat crop, why it’s always the… Read More
As tar spot continues to spread northeast across Ontario’s corn region, growers are looking to build a better defence against the yield-robbing leaf disease. Crop genetics and fungicide will likely be the one-two punch growers use to control the disease, which is characterized by tar-like speckling on the upper surface of corn leaves. The fungal… Read More
Ever since tar spot leaf disease first hit Ontario corn growers’ radar back in 2019, extension specialists and industry have been working diligently to stay a step ahead of the yield-robbing disease. Seed companies have identified hybrids in their product lineups with stronger resistance to the disease and also worked with growers to effectively manage… Read More
As the 2024 Ontario corn crop races to the finish line with help from a late summer stretch of hot weather, growers are now seeing the challenges created by spring planting conditions and pest and disease pressures. In some parts of the province, growers were able to get corn in the ground in late April,… Read More
Field research shows that the best time to tackle tar spot with a fungicide is the VT/RI stage of corn development — when the tassel is visible and silks are emerging. That’s the case again this year, says Ontario Ministry of Agriculture, Food and Agribusiness plant pathologist Albert Tenuta. He’s been testing fungicide treatments to… Read More
There are more than a few seeding, fertilizing, and scouting questions to wade through in this week’s Wheat Pete’s Word podcast, and that’s exactly how host Peter “Wheat Pete” Johnson likes it. Before answering the top agronomy questions, though, Johnson has two reminders for all of us on being courteous and on taking care of… Read More
It’s been a tough spring for planting corn in Ontario. Planting season started in late April and some growers are now just getting their last acres in the ground during the final days of June. That seven-week planting season will present challenges for growers as they try to assess yield potential and apply fungicides to… Read More
It’s not just insects that may have a jump on the crop this year in Ontario — weeds are large and in charge, and diseases, such as tar spot, could blow up from the U.S. much earlier than last year. But that’s not all the agronomic knowledge you’ll glean from this episode of Wheat Pete’s… Read More
