I sprayed 2.4-d on my bermuda lawn 4 days ago.The dandelions and other weeds are twisting but are a long way from being dead yet. The fertilizer dealer said I needed no more than 1 pint/acre.Upon reading the label, I saw it stated 2-4 pints/acre.I applied 2 pints/acre. How long before I see results? Should I apply again at 2 pints or go for 4 pints/acre? I used a 25 gal pull sprayer putting out 15 gal/acre and #3 nozzles at 5 mph. I am located in eastern NC and the temps have been in the upper 60s to 70s.
