二氯苯醚菊酯[2,2-二甲基-3-(2,2-二氯代乙烯墓)环丙酸-3-苯氧苄酯]是由Elliott等发展起来的新拟除虫菊酯,是一种高效低毒的新农药。药效试验表明,它对稻、棉、蔬、果的主要害虫,都有良好的防治效果。配合药效试验,我们测定了二氯苯醚菊酯在青菜中的残留量,观察其消失动态,以了解它在作物上的残留情况。 Permethrin [2,2-dimethyl-3- (2,2-dichloroethene tris) -3-phenoxybenzyl cyclopropionate] is a new pyrethroid ester developed by Elliott et al. , Is a new pesticide with high efficiency and low toxicity. Pharmacodynamic tests show that it has good control effects on rice, cotton, vegetables, fruits and pests. In combination with the efficacy test, we determined the residual amount of permethrin in green vegetables and observed its disappearance dynamics to understand its residue on the crop.
