What do we do with all this Fleabane?!
Sep 30What do we do with all this Fleabane?!
As you are harvesting your crop this fall season, many of you are seeing the remnants of Canada Fleabane or even full plants within your field. What many are not seeing or at least not noticing are the little rosettes at ground level, already emerged.
What can we do?
- Tillage – Many do not look to tillage in my immediate area, but this is one way to at least 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 to spray these rosettes, we must be cautious because as we know there is resistance to glyphosate and Group 2 Herbicides; therefore, we need to be selective when choosing our herbicides. 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 danger in using herbicides at this time of year is that the weed needs to be actively growing. If your area has had heavy frost or freezes, these weeds may not be receptive to the chemical, leading to poor weed control. In this case, you will either have to wait until spring or refer to the first solution.
If you are seeding wheat after soybeans and you have these rosettes in the field, you still can spray this field but you must be selective in your herbicide. I do not recommend using a 2,4-D or Dicamba herbicide in this situation. My recommendation would be to spray EragonTM at a rate of 10 acres per jug with Merge® and adding a glyphosate to take care of any other grasses that may be apparent.
No matter what your 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 them as per weed pressure and keep a good eye on these fields in the future.
Do not turn a blind eye to this problem. It will only get worst with time. It is best to be on top of the situation and take control before it takes control of you!
