芝麻叶斑病(包括叶枯病Corynesporacassicola,叶斑病Cercospora sesami,轮黑斑病Alternaria Sesami,黑斑病A.ses-amicola)和茎点枯病(Macrophominaphaseolina)是芝麻常发性病害。在我国各芝麻产区都有不同程度的发生,并在很多地区造成较严重的产量损失。国内学者对这些病害的发生及防治曾做过一些研究,但对其发生与产量损失的关系研究尚少,因而缺乏对这些病害进行经济有效防治的科学依据。为了明确芝麻叶斑病和茎点枯病混合发生对产量的影响,我们于1985年进行了这方面的研究,取得初步结果。
Sesame leaf spot (including Corynespora cassicola, Cercospora sesami, Alternaria sesami, A.ses-amicola) and stem spot (Macrophominaphaseolina) are common sesame diseases. In our country all sesame producing areas have different degrees of occurrence, and in many areas caused more serious loss of production. Domestic scholars have done some research on the occurrence and prevention of these diseases, but there is little research on the relationship between their occurrence and yield loss, so they lack the scientific basis for the economical and effective prevention and control of these diseases. In order to clarify the impact of mixed sesame leaf spot and stem spot blight on the yield, we conducted this research in 1985 and achieved initial results.
