墨玉地区,由于黄地老虎危害,秋白菜常减产50％以上。过去,本地多用高残留农药滴滴涕、六六六等防治黄地老虎,加之防治不及时,收效不大。为了控制虫害,提高白菜的产量和质量,我们于1978年用黄地老虎颗粒体病毒和辛硫磷作防治试验,试验分单喷颗粒体病毒(每次亩用粗制品10克)一次及二次,单喷辛硫磷(辛硫磷2500倍液,每次每亩50斤)一次及二次,喷施颗粒体病毒加辛硫磷(辛硫磷2500倍液50斤+颗粒体病毒粗制品10克)一次及二次和喷水(对照)共7个处理,每个处理1.5分地。第一次喷药是在8月15日黄昏时,第二次在8月26日黄昏时。
Mo Yu area, due to the hazards of yellow tigers, autumn cabbage often yield more than 50%. In the past, the local use of high residual pesticide DDT, HCH six prevention and treatment of yellow tiger, combined with prevention and treatment is not timely, with little success. In order to control pests and improve the yield and quality of cabbage, we used the yellow tiger granulovirus and phoxim in 1978 as a control test, the test single spray granulosis virus (10 grams per mu with crude products) once and two Times, single-spray phoxim (phoxim 2500 times, each 50 acres per acre) once and twice, spraying granulosis virus plus phoxim (phoxim 2500 times 50 kg + granular virus rough Product 10 grams) once and twice and water (control) a total of seven treatments, each processing 1.5 points. The first spray was at dusk on August 15 and the second at dusk on August 26.
