化学新农药“杀螟松”,对人、畜比较低毒、安全,对害虫比较速效、高效,经我们在一九七三年春、夏进行测定试验,对茶毛虫、茶蚕及茶小黑象鼻虫的药效都不低于敌敌畏;并经在茶园试验明确:50％杀螟松乳剂1000倍液对茶毛虫喷后约四小时左右即能达全部死亡(以上已报导在本刊一九七三年三期二十页)。当年秋冬季继续用国产50％杀螟松乳剂对茶蚕、茶小叶蝉、茶红蜘蛛等进行茶园试验,结果:也都有甚为良好的喷杀药效。现把秋冬季进行的试验情况与结果简介如下。
Chemical new pesticides “fenitrothing”, people and livestock relatively low toxicity, safety, relatively quick and efficient pests, by our test in the spring and summer of 1973, on the tea caterpillar, tea silkworm and black tea Weevil efficacy of not less than the dichlorvos; and tested in the tea garden clear: 50% fenitrothion emulsion 1000 times on the tea caterpillar about four hours after spraying that is able to achieve the full death (has been reported in this issue Three Seven Issues, 1973, p. 20). Autumn and winter that year with 50% of the domestic production of fenitrothion emulsion on tea silkworm, tea leafhopper, tea spider mites and other tea plant test results: also have a very good spray kill efficacy. Now the autumn and winter trials and results are as follows.
