近几年,在小麦生产上麦鞘毛眼水蝇为害逐年加重,威协着小麦高产稳产。1991—1993年渭源县承担了定西地区植保站、西北师范大学生物系等单位共同主持的”麦鞘毛眼水蝇示范防治“课题,三年示范防治9.529万亩,增产粮食175.58万公斤,总增产值16.943万元,获纯收益15.895万元。并经三年试验获小麦不同生育时期叶喷40％甲基异柳磷防治麦鞘毛眼水蝇最佳防治时期,孕穗期三年防效均在95％以上。
In recent years, wheat sheath blight on wheat sheath blight increased year by year, Wei Association of high and stable yield of wheat. In 1991-1993, Weiyuan County undertook the project of “Model Prevention and Control of Phyllostachys meyeritidis” co-sponsored by the Plant Protection Station in Dingxi District and the Department of Biology of Northwest Normal University. In the three years, 9.529 million mu of prevention and control measures were carried out to increase grain yield by 1.7558 million kilograms, Total production value of 169.33 million yuan, net income of 158.55 million yuan. After three years of experiment, wheat was sprayed with 40% methyl isofenphos at different growth stages to prevent and cure the mosquitoes. The three years’ booting control efficacy was over 95%.
