How long before or after rain is it safe to apply GrazonNext HL Herbicide?
Answer:
GrazonNext HL Herbicide is best applied when rain is not expected within 24 hours after application. Â As long as the weeds being controlled are not drenched/dripping water prior to application it can be applied after rain within a few hours.
