棉叶螨是棉花生产10大害虫为害最凶的一种,在江西棉区常有不同程度的发生为害,尤其是干旱和综合防治不力的年份或地区最为严重,对夺取棉花高产优质低耗的威胁极大。从药剂防治看,它对有机磷一类的常规农药的抗性日益增长,用提高药剂浓度和增加施药次数去歼灭害虫危害,致使造成农药极大浪费,又导致农药公害。对此,我省在1986年引进和应用高效、低毒、低残留,残效期长的新型农药克螨特,并在永修县进行了试验和示范,取得
Cotton spider mite is one of the ten most damaging types of cotton in the production of pests. It often occurs in different degrees in the cotton area of Jiangxi Province, especially in the year or area where drought and comprehensive prevention and control are not strong. Great threat.
