Abstract

The synergistic effect of the mixture of acetone extracts from Sophora flavescens and procymidone at 6 different ratio against Bortrytis cinerea Per had been tested using growth rate method in laboratory.The results showed that four ratio exhibited certain synergistic effect respectively,and the synergistic effect was highest at the ratio of 0.4∶0.6.Then the synergistic effects of the mixtures were further tested on tomato seedlings.The results showed that the synergistic ratio(SR)of the combination of 0.4∶0.6 was highest,the SR was 1.2.
