I am about to use Turflon Ester with Fusilade on a zoysia lawn to control bermuda. I've never used this before or any esters. I understand they can volatilize in warm conditions and the drift can harm non-target plants. Temps here are low's in the mid 70's to highs in the upper 90's. What precautions should I take to avoid this? I know this is something that should have started earlier in the year but I just started taking care of this yard. Should I just wait till next year?
