Applied to 1 Ac via a pull behind sprayer exactly as specified in the instructions. No evidence of Poa kill 3 weeks after application to dormant Bermuda in NC. Any suggestions?
Negate 37WG can take up to 2-3 weeks before you start seeing results but because you recently had freezing temperatures and snow the progress or kill could take longer. Per the product label in warm, moist conditions, the expression of herbicide symptoms is accelerated; in cold, dry conditions, expression of herbicide symptoms is delayed. Death of leaf tissue and growing point will follow in some species, while others will remain green but stunted and noncompetitive. Best weed control is attained when Quali-Pro® NEGATE 37WG is applied in vigorously growing weeds or desired plants. You can reapply on your dormant turf after 4 weeks if the target weeds are still present.
