Know before you buy
There is a zero-hour re-entry interval for this product. Once the spray has completely dried on the foliage, it is generally considered safe for people and pets to re-enter the area.
Yes, this formula has no residual soil activity, meaning it only kills the plants it touches. You can safely replant in the treated area shortly after the weeds have died, as the glyphosate does not remain active in the soil.
For general weed control, mix 1.5 ounces of concentrate per gallon of water. For tougher, woody weeds or brush, increase the concentration to 2.5 ounces per gallon.
The formula is rainproof within two hours of application. As long as it has had two hours to dry on the leaves, a light rain or irrigation should not affect its effectiveness.
For the best results, apply this product when temperatures are at least 60°F. Applying during warmer weather helps the plant absorb the systemic formula more efficiently, leading to a faster kill.
This is a non-selective herbicide, meaning it will kill or damage any green plant tissue it comes into contact with, including your lawn grass. It should be used for spot-treating weeds or clearing bare ground, rather than broadcast spraying over a healthy lawn.
