Enhanced dosage delivery of pesticide under unmanned aerial vehicle condition for peanut plant protection: tank‐mix adjuvants and formulation improvement

BACKGROUND Suspension concentrate (SC) is one of the most widely used formulations for agricultural plant protection. With the rapid development of unmanned aerial vehicle (UAV) plant protection, the problems of spray drift, droplet rebound and poor wettability in the application of SC from UAVs have attracted wide attention. Although some tank‐mix adjuvants have been used to enhance dosage delivery for UAV, their effects and mechanisms are not fully clear, and few formulations are specifically designed for UAV. RESULTS The type and concentration of tank‐mix adjuvant affect the dosage delivery of SC. MO501 can significantly reduce DV
