Study on the Effect of UAV Application on the Prevention and Treatment of Leaf Spot of Ascochyta araliae
In this paper,T40 plant protection UAV sprayed with Trichoderma viridis wettable powder+Bacillus polymyxoides wettable powder to prevent leaf spot disease of Ascochyta araliae.The results show that:In the two test sites,The flying height of the plant protection UAV is 6-8 meters,the flying speed is 7 meters/second,the spray width is 8-10 meters,the spray volume is 10-13 liters/minute,and the droplets are sprayed evenly.compared with the blank group,the disease rate in the sprayed group was 17.78％and 18.89％lower,and the relative control effect was 76.79％and 81.39％,respectively.Uav application has the advantages of low cost,convenient operation and high efficiency.It is recommended to use UAV spraying mixed agents in practice to prevent leaf spot of A scochyta araliae.
