| Abstract: | Gummy stem blight,usually seen on the stems, leaves and fruits, is one of the most serious threats to production of balsam pear (Momordica charantia L.) in Guangxi with reduction of the quality and heavy losses in yield. The pathogenic organisms of the disease were still obscure because several fungal species with most similar morphology were reported to be the causative agents. In this paper, the isolate in imperfect stage from the samples of gummy stem blight of balsam pear in Guangxi was identified as Stagonosporopsis cucurbitacearumbased on the morphological characteristics, inoculation experiments and phylogenetic analysis with rDNA-ITS sequences. |
| Keywords: | balsam pear gummy stem blight Stagonosporopsis cucurbitacearum identification |
