潜叶蛾是柑桔夏秋季嫩梢上的严重害虫。1980年我们在药剂筛选试验中,发现杀灭菊酯对潜叶蛾有显著的毒杀效应,使用10ppm浓度(即20%杀灭菊酯配水2万倍)能兼治幼虫和卵,击倒力强,持效期长,在全省大面积示范推广中取得显著效果(见《福建果树》1980年第4期)。1981年我们又筛选出与杀灭菊酯属同一类型的中西除虫菊酯。据试验结果,20%中西除虫菊酯5ppm(即配水4万倍) Leaf moths are serious pests on the summer and autumn shoots of citrus. In 1980 we in the drug screening test and found that fenvalerate on the leaf moth significant poisoning effect, the use of 10ppm concentration (ie 20% fenvalerate with water 20,000 times) can cure larvae and eggs, knockout Strong, long duration, the province’s large-scale demonstration and promotion achieved remarkable results (see “Fujian fruit tree” in 1980 the fourth period). In 1981, we screened the same type of pyrethrins and pyrethrins. According to the test results, 20% of pyrethrins 5ppm (that is, water 40,000 times)
