Abstract:

This study comprehensively evaluated the preparation techniques of chitosan oligosaccharide (COS) and conducted an in-depth analysis of the effects of COS and microbial metabolites on plant growth, crop quality enhancement, and pest management, aiming to enhance agricultural production efficiency and promote environmental sustainability. The results revealed the importance of COS and microbial metabolites in improving agricultural yield and maintaining environmental stability. In response to the challenges posed to food security by climate and ecosystem changes caused by natural and human activities, we propose that future research should focus on the activities of organic nanoparticles such as COS and microbial metabolites, and emphasize the necessity of advancing emerging fertilizer research to provide scientific basis and technical support for the sustainable development of agricultural production.

Key words: chitosan oligosaccharide (COS), microbial metabolites, application, biological control, promote plant growth and development, crop quality, pest management, sustainable development
