Be sure to incorporate above the small grain seed. Delay planting until soils warm up and crop emergence will be quicker. If crop injury is a concern, use this combination for barley or durum plantings. Remember, Buckle is not labeled for spring wheat, oats or rye. Apply either Far-Go or Treflan, not both, then use a postemergence herbicide if needed.
Cold temperatures prevent triallate from changing to a gas form.
Wet soils prevent triallate from filling soil pore spaces because they are already filled with water. Fall applications of granule herbicides usually are more consistent than spring applications. Fall applications allow more time for the herbicides to equilibrate in the soil, giving them time to be in a gas form, positioned to intercept weed emergence. Herbicide efficacy will increase as soils warm and dry out in the germinating weed zone. Weeds that emerge through the soil applied herbicide zone will require a postemergence application for control.
