Pathogenetic fungi stored chestnuts putrid in China and controlling methods

Five kinds of pathogenetic fungi seperated from Chinese chestnuts in storage are identified. They are Dothiorelle gregria, Colletotrichum gloeosporioides, Papularia sp, Penicillium sp and yeast. After having studied some infecting conditions and the ecological environment in storing, knew that four of them can be effectively inhibited when chestnucts are stored in modified atmosphere at low temperature, except for penicillium sp. Some nonpoison and nonpollution agents, for example patassium sorbate, can decline the loss caused by penicillum sp. Base on the study, a scheme for storing chustnuts is set up, in which the pathogenetic fungi infecting chestnus in their growth period are inhibited stored in modified atmosphere at low temperature, and the pathogenetic fungi infecting chestnuts after harvest are inhibited by appling antifungus agent.
