为筛选防治油用牡丹根腐病的有效药剂,山西潞安智华农林科技公司研究人员选择6种常用药剂进行了室内毒力及田间防效测定试验。室内采用菌丝生长速率法测定6种杀菌剂对油用牡丹根腐病的抑制率,结果显示,噁霉灵对油用牡丹根腐病病原菌的相对抑制率最高,为97.42%;其次是甲基硫菌灵的相对抑制率为95.90%;多·福、腐霉利和咪 In order to screen effective anti-oil Peony root rot medicine, Shanxi Lu'an Zhihua Agriculture and Forestry Science and Technology Company researchers selected six kinds of commonly used agents for indoor toxicity and field efficacy test. Indoor mycelium growth rate method of six kinds of fungicides on peony root rot inhibition rate, the results showed that hymexazol on peony root rot pathogen relative inhibition rate was the highest, 97.42%; followed by a The relative inhibition rate of thiophanate-methyl was 95.90%;
