Roundup 486 SL
Roundup 486 SL is a popular herbicide that comes in liquid form and works to control narrow leaf, broad leaf, and sedge weeds. Weeds and grass will look yellow in 3-5 days because the poison will react from the leaves to the roots and then kill the grass roots. Rainproof 1-2 hours after application. This will eliminate the worry of re-spraying and the risk of rain.
