枣步曲(又名枣尺蠖)是山西省柳林县枣产区的主要害虫,危害极大。近年来,由于多次大剂量使用高毒、复配农药,使枣步曲对多种农药的抗药性逐年增强。为了探索高效低毒农药对枣步曲的防治效果,确定最佳用量,2 0 0 3年进行了高氯辛微乳剂防治枣步曲的药效试验。1　材料与方法试验设 Jujube step (also known as Zizyphus jujube) is the main pests in the jujube producing area in Liulin County, Shanxi Province, which is extremely harmful. In recent years, due to repeated use of high doses of high-toxic, complex pesticides, jujube Buqu a variety of pesticide resistance increased year by year. In order to explore the effect of low-toxicity and high-efficiency pesticide on the prevention and cure of jujube steppe and to determine the optimal dosage, the high-potency micro-emulsion control of jujube steppe was carried out in 2003.
