Key Learnings From 2017 in an Ongoing Effort to Manage Glyphosate Resistant Canada Fleabane
When learning from agronomists and farmers about their experience with managing glyphosate resistant Canada fleabane, there is consensus that multiple strategies are needed and that simply tank-mixing another mode of action will not be a good long-term approach. Since 2016 we have evaluated different management tactics for Canada fleabane. We have observed the following at our Oxford and Norfolk county field locations:
Figure 1. Canada fleabane plants the following spring after surviving fall tillage. Note the plants have multiple branches at the base and were often 10-15 cm taller than plants not exposed to fall tillage.
Figure 2. Canada fleabane control with Eragon LQ at 60 mL/ac compared to the un-sprayed control. The lower 30 mL/ac rate failed to deliver acceptable control at the one field location.
Figure 3. Canada fleabane control with the 400 mL/ac rate of Engenia (dicamba) compared to the un-sprayed control. The lower 200 mL/ac rate failed to deliver acceptable control at the one field location.
Figure 4. Fall planted cereal rye was very effective at inhibiting the germination of Canada fleabane seedlings (left) compared to where it was not planted (right).
