英文摘要	Low effective availability of modern pesticides places heavy burdens on both the environment and costs to farmers. Nano-augmented delivery systems seem to be more promising to address the present challenge modern pesticides are facing. In this article, biodegradable chitosan-lactide copolymer (CPLA) was prepared and characterized as hydrophobic pesticide-pyraclostrobin carrier. Nano-precipitation method was used to fabricate pyraclostrobin-loaded nanoparticles. Loading content (LC), encapsulation efficiency (EE), size, and size distribution of the resulting nanoparticles were investigated. The size of pesticide-loaded nanoparticles can be adjusted between 77 to 128nm by varying the feed mass ratio of copolymer to pyraclostrobin from 50/1 to 5/1. Compounds contained within nanoparticles was protected from light compared with the technical material. The pyraclostrobin-loaded nanoparticles showed an initial burst, subsequent sustained and pH-controlled release profile. Compared to 25% pyraclostrobin emulsifiable concentrate (EC), the nanoparticles demonstrated better fungicidal activity against Colletotrichum gossypii Southw under long incubation time, which further exhibited sustained release characteristic.
