摘　　要：为了探究植保无人飞机喷施30%苯甲·丙环唑微乳剂对稻瘟病、纹枯病和稻曲病的田间防治效果,以及对水稻生长的影响,为植保无人飞机施药的推广提供科学依据,在水稻分蘖末期和破口期采用植保无人飞机进行药剂喷施防治水稻主要病害试验。结果表明:在减量25%的情况下,植保无人飞机喷施30%苯甲·丙环唑微乳剂对纹枯病病株和病情指数的防治效果分别为71.33%和82.72%,对稻瘟病病穗和病情指数的防治效果分别为76.36%和80.41%,对稻曲病病穗和病情指数的防治效果分别为71.11%和79.25%。该施药方式对水稻中后期主要病害防治效果均优于对照药剂和人工施药的防治效果。In order to provide scientific basis for the promotion of plant protection UAV application,field control effect of spraying difenoconazole·propiconazole 30% ME by plant protection UAV on rice blast,sheath blight and rice false smut were investigated,and the effect of the pesticide on rice growth was also evaluated at the end of tillering stage and break stage of rice.The results showed that under the condition of 25% pesticide reduction,the control efficacies of difenoconazole·propiconazole 30% ME on diseased plants and disease index were 71.33% and 82.72% to sheath blight,respectively.The control efficacies on diseased ears and disease index to rice blast were 76.36% and 80.41%,respectively,and those to rice false smut were 71.11% and 79.25%,respectively.The control effects were remarkable on main diseases of rice at the middle and late stage,and were superior to the effects of the control fungicides and artificially sprayed control.
