摘　　要：为了筛选防治花生网斑病菌的有效药剂,采用菌丝生长速率法测定12种杀菌剂原药对花生网斑病菌的室内毒力活性,筛选出防效较好的杀菌剂;选取不同类型的杀菌剂进行复配,并对花生网斑病菌进行室内毒力测定试验。结果表明:95%咯菌腈、98.6%嘧菌酯、97%咪鲜胺、95%苯醚甲环唑、95%己唑醇、95%甲基硫菌灵、97%戊唑醇对花生网斑病菌具有较强的抑制作用。87%代森联与97%咪鲜胺按1:9复配时,具有增效作用,EC_(50)值为0.673μg/mL。室内杀菌剂毒力测定结果显示试验选取的单剂和复配药剂均对花生网斑病菌的菌丝生长具有抑制效果,该结果为花生网斑病的研究提供了理论依据,为下一步田间防效试验奠定基础。In order to screen effective fungicides for preventing and controlling peanut net spot pathogen,mycelial growth rate method was used to determine the indoor virulence activity of 12 kinds of fungicides against the pathogen of peanut net spot to screen out fungicides with good control efficacy. Different types of fungicides were selected and compounded to determine the indoor virulence activity against peanut net spot pathogen. The results showed that: 95% fludioxonil, 98.6% azoxystrobin, 97% prochloraz, 95% difenoconazole,95% hexaconazole, 95% thiophanate methyl and 97% tebuconazole all had a strong inhibitory effect on peanut net spot. When 87% polyram and 97% prochloraz were compounded at a ratio of 1 to 9, it had a synergistic effect with an EC_(50) value of 0.673 μg/mL. The results of the indoor virulence test showed that both the selected single fungicides and compounded fungicides had inhibitory effects on mycelial growth of peanut net spot. This study could provide a theoretical basis for the research of peanut net spot disease, and also lay a foundation for the next field control experiment.
