近年来,拟除虫菊酯杀虫剂的开发,在农、林、卫生等害虫防制中发挥了显著的效益。它具有高效,低毒、击倒快,杀虫谱广,对人畜安全等特点,同时能克服有害昆虫对有机氯,有机磷等杀虫剂的耐药性。但在单剂使用中发现有复苏现象,为了弥补这一缺陷,国内许多单位和专业人员在剂型配方等方面进行了研究,改变了单一化,这不仅提高对害虫的杀灭效果,而且为消费者着想,降低成本,提高了经济效益。我们对市售的醇剂,乳剂二种剂型的杀虫药效,进行了比较观察、现将结果报告如下:
In recent years, pyrethroid insecticide development, in agriculture, forestry, health and other pest control has played a significant benefit. It has the characteristics of high efficiency, low toxicity, quick knockdown, broad insecticidal spectrum, safety for human beings and animals and the like, and at the same time can overcome the insecticide resistance of harmful insects to organic chlorine and organic phosphorus. However, the recovery phenomenon was found in the single-dose use. In order to make up for this defect, many domestic units and professionals conducted research on dosage forms and the like and changed the simplification, which not only increased the killing effect on pests but also increased the consumption Those who think, reduce costs and improve economic efficiency. We are on the market of alcohol, emulsion insecticidal efficacy of the two formulations were compared, the results are reported as follows:
