近二十年来,由于我国杀灭卫生害虫主要使用敌敌畏,致使各地家蝇对其普遍产生了抗性,从而用量增加,对人的毒性增强,威胁着人类的健康。因此,如何寻找高效低毒的新杀虫剂或新配方,是防治卫生害虫中急待解决的问题。 近两年来,根据国内使用情况,在现有农药中广泛进行了混配试验,并经过无数次的测定,选出了辛硫磷、二溴磷及新增效剂——增效磷(SV_1),按1:1:1的比例配成一种新的高效、速杀、价廉的新配方,暂称“PDS”,对家蝇的杀灭效果较为理想,现将结果报告如下。
In the recent two decades, the main use of dichlorvos for sanitizing pests in our country has caused widespread resistance to houseflies in various places. As a result, the dosage is increased, the toxicity to human beings is increased and the human health is threatened. Therefore, how to find new insecticides or new formulations with high efficiency and low toxicity is an urgent problem to be solved in the control of pests. In the past two years, according to the domestic use situation, extensive mixing tests have been conducted among the existing pesticides. After numerous tests, phoxim, dibromo-phosphorus and the new synergist - ), According to the ratio of 1: 1: 1 dubbed a new efficient, fast kill, cheap new formula, tentatively called “PDS”, the killing effect of house flies is more ideal, the results are reported as follows.
