摘要
采用生长速率法测定了6种杀菌剂对黄瓜褐斑病菌的毒力。结果表明,6种药剂对褐斑病菌的作用效果存在很大差异。室内测定抑菌效果最好的是50%多.福.锰锌可湿性粉剂在25 600倍液、10亿个.g-1枯草芽孢杆菌可湿性粉剂在19 200倍液时抑菌率均为100%,20%烯肟.戊唑醇、430 g.L-1戊唑醇悬浮剂和75%肟菌.戊唑醇水分散粒剂次之。该结果为田间防治试验提供了理论依据。
The toxicity of 6 fungicides for Corynespora cassiicola were tested by mycelium growth rate method.The results showed that the inhibition of 6 fungicides to Corynespora cassiicola were significantly different.Among six fungicides tested,50% Carbendazim·Thiram·Mancozeb WP and Bacillus subtilis（Ehrenberg） Cohn WP（1 billion cells·g-1） had the best inhibition of the mycelium growth of the pathogen,20% SYP 1620·Tebuconazole SC,430 g·L-1 tebuconazole SC and 75% Trifloxystrobin ·Tebuconazole WG was the second effective fungicides.
