作为防治仓储害虫使用的溴氰菊酯制剂有2.5％可湿性粉剂和2.5％乳油,后者加有增效醚,这两种制剂的商品名为凯素灵。近年来,各地对凯素灵进行的试验结果说明,在我国的储粮条件下,这是一种很有希望推广的防护药剂。目前我国农村储粮数量不断增多,由于使用凯素灵不需要象使用熏蒸药剂时那样的要求密闭条件和应用技术,因此比较适合于在广大农村中推广,作为一种防虫手段。为了今后凯素灵在仓虫上进一步试验研究的开展,现将这方面已经进行的工作作一个简单的回顾是很有益的。为此,这里小结近两年来我国在这方面的委托药效试验结果,以供参考。
As a control of storage pests use of deltamethrin formulations are 2.5% wettable powder and 2.5% EC, the latter plus a synergistic ether, the two formulations under the trade name Kai Suling. In recent years, the test results carried out by Kai Suling all over the country show that under the condition of grain storage in our country, this is a promising anti-drug agent. At present, the amount of grain stored in rural areas in our country is increasing. Because of the use of Kaixiling, it does not require the confinement conditions and application technologies required when using fumigating agents. Therefore, it is more suitable for popularizing in rural areas as a pest control measure. In order to carry out further experimental research on Kailing in Wharf in the future, it is very helpful to make a brief review of the work already done in this respect. To this end, here summarized the results of the commissioned efficacy trials in this area in our country for the past two years for reference.
