杀虫烟剂是我国防治森林害虫的主要药剂之一。目前突出的问题是成本较高,迫切需要改进配方,降低成本。我们在1964年研究使用硝酸盐代替氯酸钾做氧化剂及热熔加工法的基础上,1965年试验了两种成本较低、原料易得的新配方,并对马尾松毛虫进行防治试验,效果良好。其配方如下:林研-2号:666油状物54%、硝酸铵28%、木粉8%、滑石粉10%。林研-3号:666原粉54%、硝酸铵28%、木 Pesticide and tobacco agent is one of the main agents of forest pests in our country. At present, the outstanding problems are the high cost and the urgent need to improve formulation and reduce costs. In 1964, we studied the use of nitrate instead of potassium chlorate oxidizer and hot melt processing method based on the 1965 test two lower cost, easy to get raw materials of the new formula, and the prevention and treatment of Masson pine caterpillars, the effect is good. The formula is as follows: Lin Yan-2: 666 Oil 54%, ammonium nitrate 28%, 8% wood flour, talc 10%. Lin research -3: 666 54% of the original powder, ammonium nitrate 28%, wood
