杀虫脒防治柑桔红蜘蛛(Panonychus citri Mag.)是属于比较迟效性的药剂,根据1974年试验,25％杀虫脒水剂400倍,喷后3～4天,对成若螨杀伤达100％,直接杀卵达64.1％,由于杀虫脒对幼螨的胃毒残效长,喷后1个月检查,对叶片上卵的直接和间接杀伤达99.3％,是一种残效较长的杀虫杀螨剂。我国以前生产的均以水为溶剂,一般贮存2年以后即出现瓶壁结晶和瓶底沉淀,失去杀伤效能。为此,对杀虫脒剂型的改革,势在必行。1984 Chlordimeform prevention and control citrus red spiders (Panonychus citri Mag.) Is a relatively late-acting agent, according to the 1974 test, 25% 25% chlordimeform agent 400 times, spray 3-4 days after killing Up to 100%, directly kill eggs up to 64.1%, due to the long residual effect of chlordimeform gastric lavage on young larvae, check 1 month after spraying, the direct and indirect killing of eggs on the leaf up to 99.3%, is a longer residual Insecticidal acaricides. China used to produce water as a solvent, the general storage of 2 years after the bottle wall crystallization and bottom sedimentation, loss of killing efficiency. For this reason, reforming the dosage form of chlordimeform is imperative. 1984
