Abstract:

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.

Key words: Covering Agent, Soybean Frogeye Spot, Control Efficiency, Reduced Application and Increased Efficacy of Pesticides, Fungicide
