How to use postemergence herbicide?
Guidelines for Using Postemergence Herbicides 1 Most broadleaf weeds are best treated in the spring or fall when air temperatures are between 65 and 85° F.

When stressed by drought, weed control is poor and turf damage may occur. 3 Do not mow immediately prior to or after application. Mowing lessens the amount of herbicide that contacts weed leaf surface area. 4 Treat weeds when no rain is expected for at least 24 hours with spray applications. 5 Avoid treating on windy days because herbicide drift can injure ornamental plants. 6 Best results occur when weeds are young. 7 For acceptable control, repeat applications may be required.
