Mode of Action | 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 internode and growth point destroyed and lose reproductivity. The compound is a new type herbicide for dryland. The product can increse crop yield with its good weed killing activity and is favourable to evironment protection with its high performance and low toxicity. |
