Systemic, post-germinating herbicide to combat annual and perennial grasses of weeds. Propaquizafop is absorbed by the leaves of weeds and transferred to the roots, fleets and rhizomes. Sprayed weeds stop growing 1-2 days after application. The youngest leaves turn yellow, and the lower part of the shoots dies. Eventually all the weed is destroyed within 10-20 days, depending on the climatic conditions.
