Weeds are thriving in Ontario winter wheat fields and in many cases are beyond the size for optimum weed control.
In this episode of Real Agriculture Wheat School, Deb Campbell from Agronomy Advantage explains that winter annuals are seven to 10 days ahead of normal and that means growers will have to shift their mindset to tackle the problem.
“We need to be looking at this weed control now as opposed to our normal frame of mind where it would be after corn planting or the first week in May when we would typically be spraying,” says Campbell.
She explains that an open fall and a mild February has propelled weed growth. “All those winter annuals – chickweed, speedwell, field violet – are thriving and dandelions are a chronic problem in winter wheat. It’s not uncommon to finds weeds that are the diameter of your hand.”
