Rubber tree (Hevea brasiliensis Muell. Arg.) is an economically important perennial in tropical areas of China, e.g., in Yunnan and Hainan provinces. During the summer of 2016, leaf spots were observed on rubber trees on two plantations located in Jingping and Jiangcheng counties in Yunnan Province. The surface area of the two plantations are appro...
In July 2015, a Colletotrichum species was isolated from rubber tree leaves (Hevea brasiliensis Muell. Arg.) growing at a rubber plantation in Dehong County, Yunnan Province, China. Green leaves of rubber tree showed anthracnose-like lesions surrounded by a ring of brown tissue. Necrotic leaf tissues turned gray and paper-like gradually. The diseas...
Natural rubber is one of the pillar industries of the tropical zone in China. In July 2015, leaf spot symptoms of rubber trees (Hevea brasiliensis Muell. Arg.) were observed at rubber plantations located in Danzhou, Hainan Province, and Maomin, Guangdong Province. Lesions began as tiny brown spots surrounded by a yellow halo. The lesions expanded g...
We first reported Alternaria heveae (E.G. Simmons ) to be the pathogen that caused black leaf spot of rubber tree (Hevea brasiliensis Muell. Arg) in Heikou county in July 2014 (1). Black leaf spots that resembled the symptoms caused by A. heveae were observed on the leaves of rubber trees of the whole propagule collection nursery in Jingping County...

... N. parvum and H. investiens are tall and they are able to occupy space and absorb nutrients rapidly, so as to effectively compete with other pathogens for nutrition and space and inhibit their growth. However, studies have shown that N. parvum can cause a variety of woody plants and fruits canker disease and dieback [46][47][48][49][50][51][52], which is a harmful pathogenic fungus in agriculture. It has been reported that N. parvum had the strongest pathogenicity [53], but in this study, this property it belongs to endophytic fungi. ...
... Subsequently, it was found to occur on numerous host plants in multiple locations, suggesting that it is a pandemic member of the C. boninense species complex (Damm et al. 2012b). It was reported to cause anthracnose of rubber tree leaves in China by Cai et al. (2016). In addition, C. boninense and C. annellatum, two members of the C. boninense species complex, caused anthracnose on Hevea leaves from China and Colombia (Damm et al. 2012b;Jiang et al. 2016). ...
... E. rostratum was recorded to be associated with leaf spot of rice in Malaysia [43,44] and a pathogen of rice brown spot in Pakistan [45]. E. rostratum has been reported as causal agent of leaf spots on Zea mays, Ananas comosus, Musa paradisiaca and Hevea brasiliensis in China [46]. ...
... In 2006, another Alternaria leaf blight with similar symptom on rubber trees caused by A. alternata was identified by Roy et al. [11] in India. Our research group reported that A. heveae and A. alternata were able to incite black leaf spot of rubber tree in China [12,13]. The disease symptoms initially appear as minute spots on leaves. ...
