使用矿油(包括石油和煤焦油)乳剂防治虫害早有悠久的历史,用在防治越冬的害虫和卵上尤有特殊的价值,因为有机氯杀虫药剂如DDT、666等在煤焦油里的溶解度很大,最近更大量地使用煤焦油的溶液作为烟雾剂的原料。 苏联于1952年曾在全苏列宁植物保护分院主持下,讨论了矿油乳剂防治害虫的研究及实际使用的情况,会议极重视在植物休眠期应用矿油乳剂防治越冬的害虫或虫卵。因为在此时期使用滑润油或太阳油处理果树可以消灭
The long history of the use of mineral oil (including petroleum and coal tar) emulsions to control pests has been of particular value in the control of overwintering pests and eggs, since organochlorine pesticides such as DDT, 666 and the like in coal tar Solubility is great and more recently coal-tar solutions have been used as feedstock for aerosols. The Soviet Union in 1952 under the auspices of the All Sulein Plant Protection Branch discussed the research and practical use of mineral oil emulsion pest control, the meeting attaches great importance to the application of mineral oil emulsion during the plant dormancy to control overwintering pests or eggs. Because at this period the use of lubricants or sunflower oil treatment can be eliminated
