黄花乌头根腐病菌的室内药剂筛选

Indoor Reagent Screening of Aconitum coreanum Root Rot Disease

以黄花乌头根腐病病原菌为试材,研究了不同浓度的扑海因可湿性粉剂、多宁可湿性粉剂、甲托可湿性粉剂、多菌灵可湿性粉剂和多抗霉素可湿性粉剂对黄花乌头根腐病菌的抑菌作用。结果表明:当浓度为2 500μg/mL,50%扑海因可湿性粉剂和77%多宁可湿性粉剂对黄花乌头根腐病菌抑制作用最强,抑菌率为80%以上,而3%多抗霉素可湿性粉剂、50%多菌灵硫可湿性粉剂抑菌率在60%以上;当浓度为1 250μg/mL,50%多菌灵可湿性粉剂、77%多宁可湿性粉剂的抑菌率均在60%以上,其它药剂的抑菌效果不显著。所有以上药剂在833μg/mL浓度时的抑菌效果都不明显。

The bacteriostasis of different concentrations of flutter haiyin WP, Multi-Ning WP, A prop WP, carbendazim sulfur WP and antimycin polyoxin WP on Aconiturn coreanurn root rot disease were studied. The results showed that 50% flutter haiyin WP and 77% Multi-Ning WP could effectively inhibition the growth of the aconitum coreanum root rot disease at 2 500 μg/mL, bacteriostation ratio could reach more than 80%, but 3% antimycin polyoxin WP, 50% carbendazim sulfur WP of the bacteriostation ration was overcome 60%; the 50% carbendazim sulfur WP and 77% Multi-Ning Wp of the bacteriostation ration could reach overcome 60% at 1 250μg/mL,other reagents didn＇t have the obvious inhibition effect. All the reagents above didn＇t have the inhibition bacteriostatic at 833μg/mL.
