Treat bindweed in stubble within 2 weeks after harvest to actively growing bindweed with a tank mix of eight ounces of Picloram (Tordon 22k or Outpost 22K) with 32 ounces 4Number 2,4-D Amine per acre. Apply these herbicides at least 60 days before planting wheat in the fall to avoid stunting of wheat. Allow bindweed to brown out before tillage of stubble after treatment.
Dry and hot weather conditions during herbicide application may cause less bindweed root kill.
Picloram may be applied tank-mixed with Landmaster instead of 2,4-D to control other broadleaf weeds and grasses in the stubble. Landmaster is not available for cost share through the County.
