Abstract: Pesticide foliage treatment is used in agricultural production to protect plants from diseases, pests, or weeds. Tank-mix adjuvants added to the barrel can improve the effective utilization rate of pesticides. Herein, a comparative study was conducted to investigate the effect of three kinds of tank-mix adjuvant on the deposition, absorption, and permeation behavior of epoxiconazole and chlorantraniliprole solutions. Surface tension and contact angle results indicate that polyether-modified trisiloxane may be the best surface-active agent for pesticides, whereas methyl oleate and green-peel orange essential oil were found to be more suitable for improving pesticide deposition, absorption, and permeation in some cases. These findings indicate that various tank-mix adjuvants had different effects on pesticide application on plants. Appropriate tank-mix adjuvants need to be selected for comprehensive practical application.
