Controlling winter annual broadleaf weeds in wheat
These herbicides are active primarily through foliar uptake and have limited soil activity, so ideally they should be applied to plants with viable foliage and when temperatures are 50 degrees or higher to achieve optimum performance. If applying MCPA or 2,4-D with topdress nitrogen fertilizer, the ester formulation needs to be used as amine formulations are not compatible with liquid N fertilizers.
Starane or dicamba products generally do not provide very good mustard control, so wouldn’t be very good choices to help control ALS-resistant mustards.
Late applications for henbit control
Many producers like to wait to apply broadleaf herbicides until spring, for a variety of reasons. This normally works well for control of mustard species if they haven’t started to bolt, but is less effective for henbit control, especially if it starts to flower. Winter annual broadleaves do not generally cause much yield loss if left uncontrolled in the fall. However, these weeds should be sprayed in early spring when they are actively growing, but before they begin to bolt or flower.
Products that contain Huskie, Finesse, Glean, or Ally generally provide the best henbit control. Finesse, Glean, and Ally have both foliar and soil activity and have a wide window of application. Huskie can provide good control as a fall or early spring application, but requires thorough spray coverage on actively growing weeds for best results since it has limited soil activity. All treatments are going to be most effective if applied to henbit before it starts to bloom in spring, which can begin in early March.
