Antagonistic mechanisms of Trichoderma viride M3, Tv04-2, and T. harzianum ThB, were studied against Phytophthora nicotianae, the pathogen of stem blight disease on Schizonepeta tenuifolia by dual-culture, hydrolase activity, volatile and nonvolatile substances. Results indicated that competitive, mycoparasitism and antagonism were the antagonistic mechanisms of three Trichoderma spp. against P. nicotianae. Hydrolase activity showed that M3 was the highest for beta-1, 3-glucanases activity while ThB was the highest for proteases activity among the three T. strains, and they could produce volatile and non-volatile substances, also.
通过双培养、水解酶活性、挥发性和非挥发性物质，研究了绿色木霉M3、Tv04-2和哈茨木霉ThB对烟草疫霉（荆芥茎枯病的病原菌）的拮抗机制。结果表明，竞争、重寄生和拮抗是三种木霉菌对烟草疫霉的拮抗机制。水解酶活性表明，在这三株木霉菌中，M3的β-1,3-葡聚糖酶活性最高，而ThB的蛋白酶活性最高，并且它们也能产生挥发性和非挥发性物质。
