Abstract. The conventional pesticides are easily washed off by rainfall, resulting in a low utilization rate.To address this challenge, a novel formulation was developed by incorporating azoxystrobin (AZOX) into chitosan-polyaniline composite microspheres (CTS/PANi). The CTS/PANi microspheres exhibited excellent adhesion properties on plant leaves due to the abundance of amine groups present on their surface. The loading capacity of AZOX in CTS/PANi was approximately 9.8%. The retention rate of the AZOX@CTS/PANi formulation on cucumber leaves after flushing was 33%, which was significantly higher than that of azoxystrobin water-dispersible granules (22.5%). Furthermore, AZOX@CTS/PANi demonstrated sustained-release behavior, with a cumulative release ratio of 30% over a 48-hour period in 10% methanol. This sustained-release characteristic contributes to its long-lasting efficacy. The results of pot experiments confirmed that AZOX@CTS/PANi exhibited enhanced antifungal efficacy against Rhizoctonia solani compared to azoxystrobin water-dispersible granules after flushing.

Key words. Azoxystrobin; chitosan; polyaniline; pesticide formulation; foliar adhesion
