摘　　要：采用盆栽试验和田间试验相结合的方法,测定了12.5%阿扎霉素水剂不同质量浓度对白菜根肿病的防治效果。试验结果表明:采用12.5%阿扎霉素水剂500~1 000倍,在大白菜播种后5d第一次用药,之后每间隔7d施药1次,共施药3次,温室盆栽试验最高防治效果为87.58%,田间试验最高防治效果为80.62%,其与对照药剂500g/L氟啶胺悬浮剂的防治效果间差异显著。植保抗生素12.5%阿扎霉素水剂对白菜根肿病具有较好的防治效果,具备开发成防治根肿病新型杀菌剂的潜力。In order to provide guidance for the development of azalomycin,control effect of azalomycin 12.5% AS to Plasmodiophora brassicae were carried out under greenhouse and field conditions.The results showed that azalomycin had a good control effect to clubroot disease.The optimum concentration was 500 times-1 000 times.The optimum first using period was 5 days after sowing,and then applied every 7 dfor 3 times.The maximum control effect in greenhouse pot experiment was 87.58%,while that in field experiment was 80.62%.The control effect of azalomycin to Plasmodiophora brassicae was significantly different from fluazinam 500 g/L SC.Azalomycin has the potential to develop into new fungicide for clubroot disease control.
