Abstract: The antifungal proteins secreted by Bacillus subtilis strain TL2 were tested and showed a good inhibitive effect on the mycelial growth and the conidia germination of Pestalotiopsis theae. It was also found that when strain TL2 was inoculated, the SOD activity in tea plant were obviously changed to depress the generating speed of superoxide anion in tea plant, also the PAL activity and β-1,3-glucanases activity in tea plant were quickly increased to restrain the expansion of P. theae.
