Oct 25What do we do with all this Fleabane?!
As you are harvesting your crops this fall season, many of you are seeing the remnants of Canada Fleabane or even full plants within your field. The large plants are easy to spot, but also take note of the little rosettes at ground level that have already emerged. What do we do with these?
Tillage – Tillage is one sure fire way to control these rosettes. A shallow tillage works well since the tap roots are shallow.
Herbicide Control – You can control these rosettes by simply spraying them if you are not involved in any type of tillage. When deciding whether or not to spray these rosettes, we must be cautious because of resistance to glyphosate and group 2 herbicides. Therefore, we need to be selective in our choice. Dicamba-type herbicides work the best and can be used in the fall. In cereal crops, Buctril® M can be used in the spring on your wheat crop. The caution in using herbicides at this time of year is that the weed needs to be actively growing in order to be effective. If heavy frost has occurred, these weeds may not be able to absorb and translocate the herbicide for a good kill. In this case, you will either have to wait until spring or use tillage as outlined above.
No matter the situation, you need to be scouting your harvested fields for these rosettes. Knowledge is everything when it comes to trying to control these weeds. Take the time and walk your fields. Prioritize control of these small fleabane rosettes and keep a good eye on these fields in the future.
