新疆花生镰刀菌根腐病药剂防治筛选
Screening of control agents for root rot caused by Fusarium species in Xinjiang peanut
摘要
Abstract
This study addresses the control of peanut Fusarium root rot in Xinjiang by systematically evaluat-ing the inhibitory effects of nine fungicides on two primary pathogenic fungi,Fusarium proliferatum and F.equiseti,through in vitro screening and pot-based efficacy trials.The in vitro toxicity assays demonstrated that chemical fun-gicides exhibited significant overall inhibitory effects.Notably,43％tebuconazole showed EC50 values below 1 mg/L for both Fusarium species,with an exceptionally high toxicity against F.proliferatum(EC50=0.001 mg/L).Similarly,45％pyraclostrobin·tebuconazole displayed excellent inhibitory activity,with EC50 values generally below 5 mg/L for both pathogens.In contrast,the biological agents,300 million CFU/g Trichoderma harzianum and 100 billion CFU/g Bacillus subtilis,showed weaker inhibitory effects.The results of the pot experiments further validated the in vitro findings.At a concentration of 10 mg/L,43％tebuconazole achieved a control efficacy of 71.50％against F.proliferatum,while 70％thiophanate-methyl reached 66.66％efficacy against F.equiseti.Both fungicides demon-strated significant dose-dependent and cumulative effects,with control efficacy showing a positive correlation with fungicide concentration.Continuous application further enhanced the control efficacy by 20％-30％.In summary,the chemical fungicides 43％tebuconazole and 45％pyraclostrobin·tebuconazole are recommended as important references for the field management of peanut root rot,providing a theoretical basis for its scientific control.关键词
