 Sugarcane mosaic disease, caused by Sugarcane mosaic virus (SCMV), Sorghum mosaic virus (SrMV), Maize dwarf mosaic virus (MDMV) or Johnsongrass mosaic virus (JGMV) in Potyvirus, is one of the most important viral diseases of sugarcane. In the study, four primer pairs specific to SCMV, SrMV, MDMV and JGMV, respectively, were designed and used to detect 29 sugarcane leaf mosaic samples collected from 9 locations in Jiangxi province. The representative RT-PCR products were sequenced. The results showed that 22 samples were infected by SCMV, three by SrMV, and four were mix-infected by SCMV and SrMV. MDMV or JGMV were not identified in all samples. The result indicates that SCMV is the major pathogen of sugarcane mosaic disease in Jiangxi province, and SrMV is also a pathogen for the disease.  相似文献

车前草穂枯病是江西吉安车前草产区一种毁灭性真菌病害。本文采用菌丝生长速率法测定了火把、凯润、爱普、温立停和甲基托布津5种杀菌剂对车前草穗枯病菌(Fusicoccum sp.)的毒力,各药剂的EC50值依次为:1.2514、8.7601、20.9266、196.7915和4887.4862μg/mL。田间试验结果表明:火把对车前草穗枯病的防效最好,达94.92%,凯润和爱普也有较好的防效,分别为84.96%和82.11%,而温立停和甲基托布津的防效较差,分别只有64.02%和41.87%。  相似文献
