I sprayed 2 acres tall fescue lawn with Trimec Classic plus surfactant on Saturday 11/04. Mixed per label and applied at 1 Gal/1000 sq ft. I am in East Tennessee. Temp range mid 50s to high 30s - about 1 inch rain fell yesterday. No rain Sat-Tue. Weeds targeted are Buckhorn Plantain and Wild Onion - some spots the Plantain is 50% cover. I am seeing very little weed discoloration or leaf curling. Should I be seeing results by now? I usually spray much earlier in the Fall when temps are higher. We have had a few light freezes and more rainfall than normal this season. Should I be planning a second application at 14 days from the first spray? I over seeded the Fescue in mid September. Thanks for the advice.
