新疆棉花主要害虫有危害棉苗的蚜虫、蓟马,蕾铃期的盲蝽象和棉铃虫。特别是棉铃虫在发生较重年份,造成减产率达15％左右,过去用DDT防治棉铃虫,一般需喷药2—3次。近几年来,我们与日本住友化学株式会社进行速灭杀丁防治棉花害虫合作试验,获得了灭虫增产的良好效果。 一、速灭杀丁理化性质 速灭杀丁是日本住友化学株式会社1972年合成的一种新型拟菊酯类杀虫剂,也称速灭菊酯,化学名称为:a—氰基—3—苯氧基(艹卡)基—2—(4—氯苯基)—3—甲基丁酸酯。
The main cotton insect pests in Xinjiang have aphids, thrips, lizards and bollworm in the budding period. In particular, the occurrence of heavier cotton bollworms, resulting in reduced yield of 15%, in the past with DDT control bollworm, the general need to spray 2-3 times. In recent years, we and Japan’s Sumitomo Chemical Co., Ltd. for speeding off the killing of cotton pest insecticide cooperation test, get a good effect of pest control and yield increase. First, the speed of killing Ding physical and chemical properties of speed kill K is Japan’s Sumitomo Chemical Co., Ltd. 1972 synthesis of a new type of pyrethroid insecticides, also known as trichlorethamine, chemical name: a-cyano-3 Phenoxy (acenaphthene) yl-2- (4-chlorophenyl) -3-methylbutyrate.
