Abstract:: In order to identify metalaxyl，hymexazol and Bacillus mucilaginosus to the effects of seed germination and seedling growth of tomato,plate confrontation test，seed germination test and plug test were conducted.The results showed that B.mucilaginosus was no harmful effect by metalaxyl and hymexazol.The germination percentage of tomato seeds was about 75.2%，more than control 7.14%，treated by B.mucilaginosus at the concentration of 1.63×105 cfu?mL-1.The germination rate of tomato seeds was increased treated by metalaxyl at the concentration of 100.0,50.0,25.0，12.5 mg?mL-1，the most was metalaxyl at 100 mg?mL-1.However，hymexazol inhibited the germination of tomato seeds at the concentration of 50 mg?mL-1 to 400 mg?mL-1.When B.mucilaginosus，metalaxyl and hymexazol simple or mixed together，the root length of tomato seedlings was higher than that of control 3.88%，4.87%，and 11.56%，respectively.Plant height were higher than control 1.27%，3.80%，7.13%，The dry weight of shoot was 2.3，1.3 and 3.5 times of control，respectively.The results showed that B.mucilaginosus with metalaxyl had beneficial effect on the germination of tomato seeds，but B.mucilaginosus with hymexazol had harmful effect to it.
