8 chemicals and some mixtures against Botryodiplodia theobromae Pat., Fusarium verticillioides(Sacc.)Nirenberg, Trichoderma harzianum Rifai, Trichoderma viride Pers., and Penicillium purpurogenum Stoll were conducted in laboratory by inhibition zone in the paper. The results were shown that: CBZ and benomyl as well as copper oxine alone are much high efficacy for inhibiting most of the 5 fungi than other chemicals under the test concentrations; PPZ was found to have almost no fungicidal effect at the specified concentration. The fungicidal effect of some mixtures of CTL, DDAC, Cu-8, Benomyl and were better than alone. CTL increase the inhibiting effect of 0.5% DDAC to the 5 fungi except for Trichoderma viride Pers., and it did not increase the inhibiting effect of copper oxine; 0.01-0.08% copper oxine and 0.01-0.5% DDAC increase the inhibiting effect of benomyl to most of the 5 fungi.
