This product kills annual grasses and most annual broadleafed weeds (excluding capeweed) in specific situations and should not be used for any other purpose. Quickly kills green plant tissue on contact. Is immediately inactivated in the soil. At spraying, weeds should be growing vigorously and must not be covered with soil or heavy dew. The principle of selective weeds control with this product is that annual weeds are killed but perennial plants and clovers recover after an initial scorch.
