高粱蚜是我省主要害虫之一,几年来发生猖獗,给高粱生产造成一定损失。1965-1966年有些单位利用异丙磷的内吸作用,采用毒土法防治高粱蚜,收到了良好的效果,但每亩用药6-8两,防治成本高;在高粱耥二遍地时施药,施药时还不能根据虫情,高粱蚜发生轻时,浪费了药和工。在无产阶级文化大革命的推动下,锦州市郊区和黑山县广大贫下中农,在应用异丙磷防治高粱蚜中创造了新的经验,如黑山县姜屯公社在大面积高粱上撒施异丙磷毒土,每亩只用2两药即获得良好防治效果,锦州市郊区畜牧农场在1972年高粱蚜发生盛期,随垅撒异丙磷毒土,150亩高粱用80斤异丙磷乳油,收到了明显的防治效果。我们在学习和总结群众经验基础上,为了验证其防治效果和进一步摸清应用技术,1973年进行了室内和田间试验。室内盆栽扣罩试验证
Sorghum aphid is one of the major pests in our province, rampant in recent years, resulting in some loss of sorghum production. 1965-1966, some units of the use of isoprofos internal absorption, the use of toxic soil control of sorghum aphid, received good results, but the drug 6-8 per acre two, prevention and control costs are high; , When spraying can not according to insects, sorghum aphid light, wasting medicine and labor. Driven by the Great Proletarian Cultural Revolution, the suburbs of Jinzhou and the vast majority of poor and middle-income peasants in Heishan County have created new experiences in the prevention and control of aphids with isoflurane. For example, the Jiangtun commune of Heishan County spreads the isofetil on a large area of sorghum, Poisonous soil, only two drugs per acre that get good control effect, Jinzhou suburbs livestock farms in 1972, a peak occurrence of sorghum aphid, sprinkle with isoprofide poison soil, 150 acres of sorghum with 80 pounds of phosphorus, Received a clear control effect. On the basis of studying and summarizing the masses’ experiences, we conducted indoor and field experiments in 1973 in order to verify the effectiveness of prevention and treatment and further clarify applied technologies.
