We sprayed and used safety equipment. We also shower immediately after use (from a retired pesticide manager). The product worked great as labeled. The extra long spray nozzle with a clear plant protector and the quick attachment of protector was a great innovation. Excellent product.

ROUNDUP Weed and Grass killer with Trigger Sprayer

The ROUNDUP Weed %26 Grass Killer with Trigger Sprayer is highly rated by me for it's ready-to-use herbicide. I praise it's fast-acting, non-staining formula that delivers visible results in a matter of hours, making it highly effective for clearing driveways, patios, and around garden beds. The liquid absorbs quickly, remaining completely rainproof within 10 to 30 minutes of application. The fast-acting formula shows wilting and yellowing within hours, with complete weed death achieved in 1 to 3 days. I use ROUNDUP every spring to clear the weeds in the cracks of my patio and driveway. It works amazingly fast!
