The use of unmanned aerial vehicles (UAVs) for the application of plant protection products (PPPs) in paddy fields is becoming increasingly prevalent worldwide. Despite its growing usage, UAV spraying for rice pest control faces practical challenges, including limited canopy penetration, uneven deposition, and significant spray drift. This study investigated the impact of two tank-mix adjuvants, Wonderful Rosin (Adjuvant-1) and Tiandun (Adjuvant-2), at six volume concentrations, on the spray liquid's physicochemical properties, spray drift, plant deposition, and the biological efficacy of rice insecticides using a quadrotor UAV sprayer.

罐混助剂可提高无人机喷雾机水稻杀虫剂施用的喷雾性能和生物功效

使用无人机（UAV）在稻田施用植保产品（PPP）在全球范围内变得越来越普遍。尽管其使用量不断增加，用于水稻害虫防治的无人机喷洒仍面临实际挑战，包括冠层穿透有限、沉积不均匀和喷雾漂移严重。本研究调查了两种桶混助剂神奇松香 (Adjuvant-1) 和天盾 (Adjuvant-2) 在六种体积浓度下对喷雾液体的理化性质、喷雾漂移、植物沉积和生物功效的影响。使用四旋翼无人机喷雾机喷洒水稻杀虫剂。
