摘  要:
采用抑制菌丝生长速率法测定了腐霉利和苦参丙酮提取物对番茄灰霉病的联合毒力。结果表明:腐霉利和苦参丙酮提取液以4种配比都对该病原菌有一定的增效作用,其中腐霉利和苦参提取液配比是0.4∶0.6时,增效为1.3,盆栽试验中的增效比为1.2,确定配比0.4∶0.6为最佳浓度比例。

摘  要:
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.
