The unreasonable use of chemical pesticides has caused serious damage to crops and the ecological environment. The botanical pesticide matrine has attracted attention as an environmentally friendly pesticide. Compared with traditional spraying methods, unmanned aerial vehicle (UAV) spraying has the advantages of safety, rapidity, uniform droplets, low dosages, and no terrain or crop restrictions. In this study, matrine OD was prepared according to the application requirements of flight prevention preparations using three different emulsifiers. The stability, wettability, particle size and distribution, and spraying performance of matrine OD were studied. The results indicated that when the amount of emulsifier was 8%, the three types of matrine OD had good stability. The stability, wettability, particle size and distribution, and spray performance of the suspension prepared using emulsifier VO/03 were better than the other two emulsifiers. Therefore, matrine OD prepared using 8% VO/03 could be used for ultra-low-volume sprays and aerial applications. In this study, we provide a theoretical basis and technical guidance to develop pesticide formulations for aerial applications.
化学农药的不合理使用对农作物和生态环境造成了严重破坏。植物源农药苦参碱作为一种环境友好型农药受到了关注。与传统喷雾方法相比，无人机喷雾具有安全、快速、雾滴均匀、用量低以及不受地形和作物限制等优点。在本研究中，根据飞防制剂的应用要求，使用三种不同的乳化剂制备了苦参碱OD。研究了苦参碱OD的稳定性、润湿性、粒径及分布和喷雾性能。结果表明，当乳化剂用量为8%时，三种类型的苦参碱OD具有良好的稳定性。使用乳化剂VO/03制备的悬浮液的稳定性、润湿性、粒径及分布和喷雾性能优于其他两种乳化剂。因此，使用8%VO/03制备的苦参碱OD可用于超低容量喷雾和航空施药。在本研究中，我们为开发航空施药农药制剂提供了理论依据和技术指导。
