灭蚜菌是一种防治蚜虫的生物农药。瓢虫、草蛉等是蚜虫在自然界的重要天敌。为了明确灭蚜菌对蚜虫天敌有无影响,1993年我们在果树上进行了此项药剂试验。1 材料与方法1.1 供试药剂1.1.1 灭蚜菌(中国农科院生防所提供)。1.1.2 氧化乐果(沈阳新城化工厂生产)。1.2 供试果树 3年生苹果树(间作小麦)。1.3 试验方法 试验设喷200倍、400倍、600倍、800倍灭蚜 Offspout aphid is a biological pesticide against aphids. Ladybugs, weeds, etc. are important natural enemies of aphids in nature. In order to clarify whether the phytophagous aphid natural enemies have any effect, in 1993 we carried out on the fruit of this drug test. 1 Materials and Methods 1.1 for the test drug 1.1.1 imazethapyr (provided by the Chinese Academy of Agricultural Sciences). 1.1.2 Omethoate (Shenyang Metro Chemical Factory production). 1.2 for test fruit tree 3-year-old apple tree (intercropping wheat). 1.3 Test Method The test set to spray 200 times, 400 times, 600 times, 800 times off aphids
