摘    要:采用平皿测定方法分别对黑龙江、云南、湖北和湖南等水稻主产区的13个当地主栽水稻品种进行了种子带菌检测和分离鉴定,研究了5种不同杀菌剂和2种水稻专用种衣剂对种子带菌的消毒处理效果,结果表明,水稻种子表面携带的优势菌群主要为Fusarium,Penicllium,Rhizopus,Cladosporium,Aspergillus;种子内部寄藏的真菌主要有Fusarium,Alternaria,Cladosporium,其他分离频率较高的寄藏真菌还有Penicillium,Aspergillus和Rhizpous等,不同水稻品种之间种子表面携带真菌种类有较大差异。种子内部寄藏真菌种类差异不大,20%克福甲水稻种衣剂、20%克多甲水稻种衣剂、甲基立枯磷和福美双对于种子带菌消毒辣处理具有良好的效果,显著优于多菌灵、恶霉灵和三唑类杀菌剂腈菌唑。

关 键 词:水稻  带菌检测  杀菌剂  种子包衣  消毒处理

Abstract:Seed borne fungi and disinfection effect of several fungicides to seed pathogens were determined by means of perti dish testing. The results showed that Fusarium, Penicillium, Rhizopus, Cladosporium, and Aspergillus were main seed borne pathogens on the surface of 13 major rice varieties from Heilongjiang, Hunan, Hubei, and some other provinces in China. Fusarium, Alternaria, and Phoma represented main seed borne pathogens inside. The fungi on the surface of seed expressed significantly difference among experimental varieties, but seed borne fungi inside showed no difference. 20% Carbofuran Thiram Rizolex seed coating formulation (SCF),20% Carbofuran Carbendazim Rizolex SCF of rice,Thiram and Rizolex provided good controls for seed borne fungi. Their inhibiting effect were much better than that of Carbendazim, Myclobutanil and Hymexazol.
Keywords:rice  testing of seed borne fungi  fungicide  seed coating treatment  disinfection  effect of fungicides
