Antifungal activity of chitosan on Rhizopus stolonifer and Monilinia fructicola and its control effect on soft rot of peach fruits.

The effects of chitosan on soft rot of peach fruits at room temperature or 4 deg C were investigated. When fruits were treated with chitosan (5 or 10 mg/litre) after inoculation with R. stolonifera followed by 4-8 or 30 days of storage at room temperature or 4 deg , respectively, disease was reduced. The disease control effect was equivalent to that of prochloraz (0.5 mg/litre). Chitosan inhibited radial growth of R. stolonifer and M. fructicola in vitro. At concentrations of >2 mg/litre, chitosan induced excessive branching, hyphal swelling and shortening of hyphal segments in R. stolonifer and M. fructicola, and induced plasmolysis in hyphal cells of R. stolonifer.
