KNOW YOUR GROUPS

HERBICIDE RESISTANCE



If you’ve experienced weeds that continue to grow through your herbicide application, small patches of escapes, or excellent control in some areas of your field but terrible in others, odds are you’ve encountered herbicide resistance.

Although there are over 200 different products registered for use in the western Canadian cereal herbicide market, over 98% of them are spread across a mere five groups.


SO WHAT CAN YOU DO?



Know your groups. Rotating to herbicides that are from new or different groups is a well-known strategy for managing resistance, but you need to make sure your new herbicide actually uses a different group.


But knowing your herbicide groups and proper herbicide rotation isn’t enough, growers need to fully commit to an Integrated Pest Management plan (IPM), employing a wide variety of resistance management strategies.
