What’s benefits of Chitosan in agriculture？
1.High antimicrobial activity
One of the most important proprieties of chitosan is its high antimicrobial activity against a wide variety of microorganisms such as fungi,bacteria and virues.
The inhibition was observed at different pathogen development stages such as mycelial growth, sporulation, spore viability and germination,and on the production of fungal virulence factors.
2.Induce plant resistance
Chitosan at low molecular weight acts as a powerful biotic elicitor, It’s able to induce plant defence responses and to activate different pathways that increase the crop resistance to diseases.By activating a plant’s immune system which prevent pathogen invasion and bad external environment.
3.Used on Seed treatment
Chitosan has the high molecular weight,it confers to chitosan biopolymer characteristics, so that it can be used as film,forming physical barriers around the seeds preventing the pathogen infection.
Besides,chitosan has the ability of high antimicrobial activity and eliciting plant resistance,so it has widely used on seed treatment.
3.Changes rhizosphere microbes population
Promote growth of Trichoderma spp. Aspergillus, Bacillus subtillis, Bacillus thurengenesis.
