The inhibitory effects of 2 bactericides were tested by growth rate method and pendant drop method. The component of one bactericide is Paebacillusni polymyxa, the other is Bacillus subtilis. The results showed that 2 bactericides had inhibitory effects of Neurospora sp. and Penicillium sp.. The bactericide of Paebacillusni polymyxa had good inhibitory effects on spore germination of Neurospora sp. and Penicillium sp., the inhibitory rates were 90.44% and 65.04%, respectively. So it can be used as inhibitor of spore germination. The bactericide of Bacillus subtilis had good inhibitory effects on mycelia growth of Neurospora sp. and Penicillium sp., the inhibitory rates were 36.29% and 46.66%, respectively. Therefore it can be used as the inhibitor of mycelia growth.
