摘　　要：为明确云南澳洲坚果黑果病的致病菌和防治的化学药剂,给黑果病的大田防控提供依据,试验通过采样、病原菌分离、致病性测试、形态学和分子生物学等方法鉴定病原菌;采用含毒培养基进行室内药剂毒力测试,筛选出防治药剂。澳洲坚果黑果病病原菌鉴定为Calonectria pseudoreteaudii。药剂毒力测试结果:选用14种药剂参与测试,抑制率达75%以上的药剂有唑醚·甲硫灵、多菌灵、甲基硫菌灵、丙环·咪鲜胺、氟唑菌酰羟胺、肟菌·戊唑醇等6种药剂。In order to identify the pathogenic bacteria and select chemical agents against macadamia nut fruit black disease,experiment was conducted by using sampling,pathogen isolation,pathogenicity test,morphology and molecular biology.Furthermore,virulence test in toxic medium indoors was carried out to find out the control agent.The pathogen caused fruit black disease on macadamia nut was identified as Calonectria pseudoeteaudii.Toxicity test showed there are six drugs in all tested 14 ones have inhibition rate of more than 75%,they are zolyl·methionine,carbendazim,thiophanate methyl,prochloraz·prochloraz,fluconazole acyl hydroxylamine and oxime·tebuconazole,respectively.
