营口地区在引进推广0.5％乙基1605炉渣颗粒剂防治玉米螟技术的基础上,摸索配制出一个新剂型——3％乙基1605颗粒剂。经五年试验结果表明,新剂型防螟效果超过原剂型。据1983年各试验点统计,3％乙基1605颗粒剂防治玉米螟,在米田防效88％,高粱田防治93.3％,同时具有兼治玉米蚜虫的效果(防效达97.5％)。与目前生产上应用的其它化防相比,具有经济、高效、保护天敌、不污染环境等特点。
Yingkou area in the introduction of the promotion of 0.5% Ethyl 1605 slag particles on the basis of corn borer prevention and control, to explore the preparation of a new dosage form - 3% Ethyl 1605 granules. After five years of test results show that the new formulations of stem borer effect than the original dosage form. According to the statistics of each test point in 1983, 3% Ethyl 1605 granules prevented and controlled corn borer, controlled 88% in rice field and 93.3% in sorghum field, and also had the effect of controlling corn aphid (control efficiency 97.5%). Compared with the other chemical defense currently used in production, it is economical, efficient, protects natural enemies and does not pollute the environment.
