Weed resistance in Western Canada isn’t new and it’s not going away.
There’s no easy way to wrestle resistant biotypes to the ground. Weed species resistant to certain herbicides were first discovered in Western Canada in the early 1970s and the list continues to grow every year. Herbicide resistant weeds are coming to a field near you – if they’re not already there.
But don’t give up. Practicing good chemical rotation, using high quality certified seed, well-timed tillage, and a dozen other strategies will help you manage weed resistance in your fields.
You can ignore them but once herbicide resistance in a weed species develops in a field, the problem doesn’t go away. You need to manage the threat proactively.
Weed control becomes a much more complex issue once resistant weeds show up in your fields. If you suspect a weed is resistant, confirm the type of resistance by having it analyzed. Your P&H Retail can help with this test.
Following is a list of integrated management strategies to combat herbicide resistant weeds. Although each strategy might only make a small difference, put together they can proactively delay the serious threat of weed resistance.
