T90-1 Screening Progress and Its Application for Control of Botrytis cinerea Pers.
T90-1木霉菌的筛选和对草莓灰霉病菌作用机制的研究

Trichoderma spp. are promising biocontrol agents (BCAs) of plant diseases. Trichoderma can decompose cell wall of some plant pathogenic fungus through secreting chitinolytic enzymes. Trichoderma were implanted by ion to produce aberrance. Whereafter first screened 12 aberrance of Trichoderma strains through eyeballing. And then screened 12 aberrances and CK through four ways again. T90_1, author was selected from these aberrance strains and CK. Further experiment demonstrated that T90_1 can hyperparasitize Botrytis cinerea Pers. through enwind, infection, attachment filament etc. Zymolytic liquid of T90_1 can decompose mycelial wall that account for T90_1 excreteing chitinolytic enzymes during zymolysis.
