菵草是长江流域及西南地区稻茬麦田的主要杂草之一。精噁唑禾草灵对菵草有较好的防除效果,但由于长期单一使用精噁唑禾草灵防除麦田禾本科杂草,菵草对其产生了较高的抗药性。每亩用69克/升精噁唑禾草灵水乳剂80毫升已控制不住麦田菵草危害。菵草在苏南等稻麦连作区已成为麦田主要的禾本科杂草。
Grifola frondosa is one of the main weeds in the rice fields in the Yangtze River and Southwest China. Fenoxaprop had good control effect on Potamogeton crispus. However, Potamogeton crispus had higher resistance to it due to long-term single use of Fenoxaprop-P-ethyl to control weeds in wheat field. 69 grams per acre or fenoxaprop dextrin emulsion 80 ml has not controlled the hay field hay harm. Tamarix chinense in the southern Jiangsu and other areas have become the main crop wheat weeds.
