摘要
[目的]明确芝麻黄花叶病毒病田间流行规律，为防治该病提供参考。[方法]于2014年调查芝麻黄花叶病毒病的田间发生、流行规律。[结果]芝麻黄花叶病毒病的发生、流行与芝麻的生育期和蚜虫发生密切相关。苗期、蕾期是感染芝麻黄花叶病毒病的敏感期。蚜虫发生高峰15 d后，病害出现发病高峰。[结论]调节芝麻播种期，使苗期、蕾期，特别是蕾期错过蚜虫发生高峰能有效预防芝麻黄花叶病毒病的发生。
Abstract
Objective] To study the epidemic characteristics of sesame yellow mosaic virus disease in fields to provide references for the pre-vention and control of the disease.[Method] In 2014, the appearance and epidemic characteristics of sesame yellow mosaic virus disease in fields were investigated.[ Result] The appearance and epidemic characteristics of sesame yellow mosaic virus disease in fields was associated with the combination effect of the growing stage of sesame and aphid occurrence .Sesame plants were susceptible to sesame yellow mosaic virus in the seedling and early flowering stages.The morbidity peak occurred 15 d after the aphid peak.[Conclusion] Regulating the sowing date of sesame to prevent the aphid peak from occurring in the seedling and early flowering stages can effectively prevent the occurrence of sesame yellow mosaic virus disease.
