Application

 Quizalofop-p-ethyl, a selective systemic herbicide, has a high selectivity between grass weeds and dicotyledons crop. It is absorbed in a few hours by stem and leave and conducted to the whole body of annual weeds in 24hours, mainly cumulating in the top organs and intraformational meristem. Weeds conduct Quizalofop-p-ethyl rapidly to subterranean stem after administration, having its internodes and growth point destroyed and lose reproductively. The compound is a new-type herbicide for dry land. The product can increase crop yield with its good weed killing activity and is favorable to environment protection with its high performance and low toxicity. It widely used in Crops and Weeds.
