How long does it take WipeOut® to kill weeds and grass?
WipeOut® Total Weed & Grass Killer will start to work within 1 to 2 days, with total kill in 4 to 7 days. Within 48 hours of applying WipeOut® you will begin to see weed leaves changing colour and turning brown; total burn down will occur in 7 days. WipeOut® is one of the fastest working weed and grass killers available. Weather conditions play a part in how fast and effective WipeOut® will be. Cool temperatures and dry soil conditions place plants under stress, which reduces the speed of action for this product. Rainfall within 4 hours of applying the product may also reduce its effectiveness.
