Weed & Grass Killer, 40-oz. Concentrate

Spectracide Weed & Grass Killer Concentrate is a nonselective weed and grass killer that kills weeds and grasses down to the root. It's formulated for spot treatment of weeds and grasses on patios, walkways and driveways; around flowers, shrubs and trees; and along fences and foundations. This formula is rainproof in 15 minutes — rainfall or watering after 15 minutes won't wash away effectiveness. Spectracide Weed & Grass Killer Concentrate delivers visible results in as fast as 3 hours. Plant new flowers, trees and shrubs in the treated area after just 1 day. For best results, apply during warm, sunny weather when the temperature is over 60 degrees. Mix with water and apply with a tank sprayer at the rates directed on the product label. Completely cover the leaves of the target vegetation. Protect desirable plants with a piece of plastic or cardboard - if desirable plants are accidentally sprayed, wash with water immediately.
