Crop researchers and agronomists are encouraging Ontario farmers to continue to follow established stewardship recommendations when using dicamba herbicides. Last week, a U.S. court decision to cancel the registration of in-crop use of dicamba herbicides left regulators, product manufacturers, herbicide applicators and farmers scrambling to understand the ramifications of the ruling and the implications for… Read More

If you’re looking for a little snack and happen to be standing in a patch of weeds, it’s entirely possible the plants at your feet are edible — maybe even tasty. If you’re looking for help on which one to eat, you might be surprised to learn that Ontario’s weed specialist can tell you not… Read More
With poor spring planting conditions across Ontario, many farmers have run out of time to get major crops in the ground and thousands of acres will remain unplanted in 2019. What should farmers do with those acres? We asked Ontario Ministry of Agriculture, Food and Rural Affairs weed management specialist Mike Cowbrough and RealAgriculture agronomist… Read More
Retiring alfalfa fields used to be a simple process. Conventional tillage farmers would just drop the mouldboard plow in the fall, while those under a minimum tillage system would rely on a glyphosate burndown before planting a new crop the following spring. With the introduction of glyphosate tolerant (GT) alfalfa, however, glyphosate is no longer… Read More
If you have weeds pop up prior to planting soybeans you can control them with a burndown herbicide application. But what happens when rain and wind conspire to prevent you from applying a burndown and you have to control weeds after planting? That’s the situation many Ontario growers are facing in 2019 as the wet… Read More

Can Ontario winter wheat growers mix ammonium thiosulphate (ATS) with herbicides and fungicides to address sulphur deficiency symptoms or should they apply it separately with streamer nozzles? That’s a question Mike Cowbrough and Joanna Follings wanted to answer with 2018 research plots. The Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist and cereals… Read More
There are a number of reasons why herbicides sometimes fail to control weeds. Perhaps surprisingly, one of the easier things to rule out is whether the weed is herbicide resistant. Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike Cowbrough says many universities across Canada conduct testing for herbicide resistance, but growers have… Read More
Ontario ministry of agriculture weed specialist Mike Cowbrough says it’s easy to pick on a herbicide when it doesn’t meet your weed control expectations. Unfortunately, he says, most growers don’t often have an opportunity to compare herbicide programs in their own field using check strips or unsprayed areas to test performance. But Cowbrough does have… Read More
Many agronomists talk about the importance of multiple modes of action when planning a weed control program. In this episode of RealAgriculture’s Soybean School, Ontario Ministry of Agriculture, Food and Rural Affairs weed specialist Mike Cowbrough shows you why. We catch up with Cowbrough as he surveys a patch of Canada fleabane that has survived… Read More
By François Tardif Many master gardeners would tell you that to maximize your vegetable yields, rows need to be oriented in a north-south manner. This is supposed to maximize light interception by the crops, which in turn maximizes photosynthesis. In contrast, east-west rows have more shading and this negatively impacts yields. Is the same true… Read More
