On-Farm Applied Granular Herbicide products for the control of wild oats and kochia after oats
- Research Topic: Insect/Disease/Weeds
- Back to Project Listing
Herbicide resistance of tough to control weeds, such as kochia and wild oats, is an ongoing problem on the Canadian Prairies. Herbicide resistance surveys conducted over the last two decades on the Prairies continue to demonstrate the increasing prevalence of herbicide-resistant weeds. With increasing incidence of herbicide resistance, utilization of different herbicide groups for control of resistant types is essential to ensure farmers don’t lose crop yield to weed pressure. Herbicide resistant weeds cost farmers a significant loss in income every year, at an estimated $340 million in Saskatchewan alone.
The first objective of this demonstration was to evaluate the efficacy of Edge® and Fortress® Microactiv herbicides on wild oat and kochia populations when applied to oat crop residue. The second objective was to demonstrate whether a light (45° tine angle) or heavy (70 to 90° tine angle) harrow would affect herbicide efficacy.
