三氯杀螨醇兼具有杀成螨、幼螨、若螨和螨卵的效果,因此对茶树上的多种害螨[茶橙瘿螨(Acaphylla thece Watt),茶叶瘿螨(Calacarus carinatus Green)、茶短须螨(Brevipalpus obovatus Donn)、咖啡小爪螨(Oligonychus coffeae Nietner)有良好防效、残效期长。世界主要产茶国均将此药作为茶园杀螨剂的首选品种。我国茶区的害螨不但种类多,而且发生普遍为害严重,是夏秋茶期影响产质量的一个重要因素,有的茶区也已在茶园中应用三氯杀螨醇防治,但它究竟是否适宜于茶园中推广,为此,1980年曾对三氯杀螨醇的安全使用问题进行研究。
Dicofol also has the effect of killing adult mites, young mites, nymphs and mite eggs, and therefore has been shown to be effective against a number of pest mites [Acaphylla thece Watt, Calacarus carinatus Green, Tea Short Brevipalpus obovatus Donn and Oligonychus coffeae Nietner have good control effect and long residual period. The world’s major tea producing countries have this drug as the preferred species of acaricide. There are many kinds of pest mites in the tea area of our country. In addition, the occurrence of pest mites in the tea area is very serious. It is an important factor affecting the production and quality of tea in the summer and autumn. Some teas have also been used in the tea plantation to control dicofol. However, For this reason, the question of the safe use of dicofol was studied in 1980.
