Abstract:

Chitosan has excellent antibacterial activity and natural non-toxicity, good biocompatibility, biodegradability and renewability, and extensive raw material sources. In order to fully understand the effect of chitosan on plant pathogens, this paper summarized four kinds of action modes of chitosan on plant pathogens, namely charge effect, sedimentation, chelation and induction, analyzed the main factors affecting the bacteriostatic effects of chitosan on plant pathogen, including pathogen, chitosan, using conditions and the others. Meanwhile, it pointed out some problems in the research field: various methods, different results, and even opposite conclusion of the research on chitosan acting on plant pathogen at present. Adopting advanced equipment, establishing three-dimensional biological cell model and adopting unified research method or developing research standard were suggested to improve the study of chitosan acting on plant pathogen, so as to provide a theoretical basis for the development of novel plant disease control agent with chitosan as the active ingredient.

Key words: chitosan, plant pathogen, antibacterial activity, mechanism of action, influencing factor
