上海郊区桔农历来都使用三氯杀螨醇防治柑桔全爪螨,由于长期连续使用同一种药剂而出现了防治效果降低、害螨对三氯杀螨醇这种药剂产生抗药性的现象亦愈来愈严重。为了寻找替代三氯杀螨醇的农药,有效地控制柑桔全爪螨对桔树叶片的严重为害,我们于1984年在崇明县城桥镇东门果园(桔园)使用了六种药剂进行了防治柑桔全爪螨的试验,现将防治试验结果整理于后。供试药剂及浓度(见第114页表)试验方法试验小区采用随机排列方法。各处理设二次重复,每一重复,处理2株桔树。以4
Citrus farmers in the suburbs of Shanghai have always used dicofol to prevent and cure citrus red mite. Due to long-term continuous use of the same pesticide, the prevention and control effect has been reduced. Pesticide resistance to dicofol has also become more and more serious. In order to find an alternative dicofol pesticide to effectively control the citrus red mite on the orange tree leaves serious damage, we in 1984 in Chongming County Town East Gate Orchard (Orange Garden) using six agents for the prevention and treatment of citrus Claw mites test, now the results of prevention and treatment after finishing. Test agents and concentrations (see table on page 114) Test methods The experimental plot using random arrangement method. The treatment set up two repeated, each repeated, dealing with two orange trees. With 4
