摘要
为减少东北春大豆杀菌剂的施用量,在大豆灰斑病发病初期进行一种叶面遮盖剂喷施,研究其对大豆灰斑病的防控效果。以无人机喷施杀菌剂为施药对照,以不喷施任何药剂为空白对照。结果表明,喷施叶面遮盖剂对大豆灰斑病的防效达72.50%,同时有增产的效果,其增产率为16.00%。同喷施杀菌剂防控大豆灰斑病相比,叶面遮盖剂的使用更符合目前减施增效的农药使用政策。
In order to reduce the dosage of fungicide in spring soybean production in northeast China,a leaf covering agent is used to control the soybean frogeye leaf spot.The control is spraying fungicide with unmanned aerial vehicle,and the blank control is spraying nothing.The result show that leaf covering agent could effectively prevent and control soybean frogeye leaf spot and increase yield.The control effect and yield increasing rate is 72.50%and 16.00%respectively.Compared with the application of spraying fungicide,the application of leaf covering agent is more consistent with China’s current pesticide application policy of reducing application and increasing efficacy.
