Unmanned aerial vehicles (UAVs) are widely used to improve the efficiency of pesticide applications. Low-volume spraying operations require more efficient deposition of droplets on the target surface. Therefore, pesticide deposition and retention on plant surfaces is a serious challenge for modern precision agriculture. Tank-mix adjuvants have been used to improve spray dilutions performance; however, their effects on the physicochemical properties of spray dilutions, dosage delivery, and pesticide dosage are unclear.
Tank-mix adjuvant 8860 significantly improved the physicochemical properties of spray dilutions, inhibited spray droplets rebound, improved the wetting and spreading performance of spray dilutions on wheat leaves, and increased the effective deposition of tebuconazole on wheat leaves. Even when its dosage was reduced by one-third, the spray solution still showed excellent disease control and effective deposition of the active ingredient on wheat leaves.
The use of appropriate tank-mix adjuvants in UAV-based plant protection for wheat can significantly improve the performance of spray dilutions, increase the efficiency of pesticide dosage delivery, and improve disease control. These adjuvants can also help reduce the pesticide use while ensuring their effectiveness. © 2022 Society of Chemical Industry.
无人驾驶飞行器（UAV）被广泛用于提高农药施药效率。低容量喷雾作业要求在目标表面上更有效地沉积液滴。因此，农药在植物表面的沉积和保留是现代精准农业的一个严峻挑战。罐混助剂已被用于改善喷雾稀释液的性能；然而，其对喷雾稀释液的物理化学性质、施药量和农药剂量的影响尚不清楚。
助剂 8860 显著改善了喷雾稀释液的物理化学性质，抑制了喷雾液滴的反弹，提高了喷雾稀释液在小麦叶片上的润湿和扩展性能，并增加了戊唑醇在小麦叶片上的有效沉积。即使将其用量减少三分之一，该喷雾溶液仍表现出优异的病害控制和戊唑醇在小麦叶片上的有效沉积。
在基于无人机的小麦植保中使用适当的罐混助剂可以显著提高喷雾稀释液的性能，提高农药施药量的效率，并改善病害防治效果。这些助剂还可以帮助减少农药使用量，同时确保其有效性。© 2022 英国化学工业协会。
