磷畏(phosvel)是一种新的有机磷杀虫杀菌剂,其有效成分为甲基苯溴硫磷。磷畏乳剂含有效成分34%。磷畏对蛾蝶等鳞翅目害虫特别有效。据日本农林省农事试验场试验,于二化螟一化期(6月30日)喷射1,000倍磷畏乳剂,7月25日检查,水稻被害茎率为0.07%,经1,000倍杀螟松乳剂防治的,被害茎率为0.14%,对照为5.14%;二化期8月24日喷射700倍磷畏乳剂,9月20日检查,水稻被害茎率为2.2%,经1,000倍杀螟松乳剂防治的,被害茎率为1.1%,对照为19.8%。
Phosvel is a new organophosphate insecticide and fungicide with the active ingredient methylthionophos. Phosgrain emulsion containing 34% active ingredient. Phthalocyanine is particularly effective against Lepidoptera pests such as moth butterfly. According to the Japan Agriculture, Forestry and Foodstuffs Farm Experimental Field Test, a 1,000-fold injection of Phoxim was sprayed on the rice stem borer (June 30) during the first phase of the Borer borealis test. The stubble rate of rice was 0.07% on July 25, Control, the damage rate of 0.14% stems, the control was 5.14%; the second period of August 24 injection of 700 times the PDT emulsion, September 20 inspection, the damage rate of rice stems of 2.2%, 1,000 times fenitrothion emulsion Control, the victim stalk rate was 1.1%, control was 19.8%.
