灭幼脲Ⅲ号〔化学名为豆1-2-氯-(苯甲酰基)-3(4-氯苯基)脲,化学结构式为:为苯甲酰基苯脲类化合物,是一种干扰几丁质沉积的新型杀幼虫剂。它对鳞翅目等害虫的杀伤力很强,对人、畜毒性低,对天敌安全,它在植物和昆虫体内较稳定,因而残效期较长。中国农业科学院茶叶研究所从1982年起用灭幼脲Ⅲ号(由吉林通化市第四化工厂提供样品)对茶尺蠖进行室内药效和田间防治试验,现将试验结果报道于下。
Chlorbenzuron III [chemical name beans 1-2-chloro - (benzoyl) -3 (4 - chlorophenyl) urea, the chemical formula is: benzoyl phenyl urea compounds, is a kind of interference A new type of larvicidal agent for the deposition of butyl. Its Lepidoptera and other pests of the lethality is very strong, low toxicity to humans, livestock, natural enemies of security, it is more stable in plants and insects, and therefore residual longer. Tea Research Institute of Chinese Academy of Agricultural Sciences from 1982 on the use of diflubenzuron III (from the fourth chemical plant in Jilin Tonghua City, the sample) on the tea scallop indoor efficacy and field control trials, the test results are reported below.
