In order to verify the control effect of drones on citrus diseases and insect pests, EAVISION conducted comparative experiments on the prevention and control of different diseases and insect pests in the main producing areas: Guangxi, Hunan, Jiangxi, Zhejiang and other places. Among them, red spider mites are the pests with the highest occurrence probability of citrus, and the onset is fast. , The characteristics of prevention and control make it a big worry for growers all the time. Citrus spider mites mainly damage leaves, green shoots, fruits, etc., causing many small gray-white spots on the victimized parts, losing their inherent luster, often causing a large number of leaves, flowers, and fruits in late spring and early summer, which seriously affects the yield and tree vigor of citrus. . In order to explore the flying control effect of the currently popular terminal killer, EAVISION and Guangxi Specialty Crops Research Institute, located in Lingui District, Guilin City, used the EAVISION drone-agrochemical combination scheme to conduct a field efficacy test of citrus spider mites, and achieved ideal results. prevention effect.
