Abstract
This study was conducted in order to determine the fungi and bacteria associated with tomato plants at Cameron Highlands Malaysia. The fungi which have been isolated and detected from tomato plants were: Fusarium oxysporum, F. solani, F. acuminatum, Rhizoctonia solani, Colletotrichum boninense, C. acutatum and Phoma destructiva. The bacteria which have been isolated and detected from tomato plants were: Ralstonia solanacearum, Xanthomonas vesicatoria, X. gardneri and Pseudomonas syringae. While the most pathogenic fungi were C. boninense, P. destructive and F. oxysporum with the disease incidence (89.6%, 86.6%, 85.6%) respectively, the most pathogenic bacteria were X. vesicatoria and R. solanacearum with the disease incidence (96.6% and 87.6%) respectively.
Highlights
An estimated 124.5 million tonnes of tomatoes (Lycopersicon esculentum Mill.) are produced annually through-How to cite this paper: Rashid, T.S., Sijam, K., Awla, H.K., Saud, H.M. and Kadir, J. (2016) Pathogenicity Assay and Molecular Identification of Fungi and Bacteria Associated with Diseases of Tomato in Malaysia
The pathogenicity test revealed that the F. solani and F. acuminatum were the least pathogenic to tomato plants as compared to F. oxysporum under test conditions even though the Fusarium species were commonly found in tomato plantations
Different tomato plant pathogens were collected from various tomato fields in Cameron Highlands, Pahang, Malaysia

Production of tomatoes tends to be more successful in highland areas in Malaysia, mainly due to the milder temperatures there. Cameron Highlands is a popular location for large-scale tomato cultivation. There are still a large number of fungal and bacterial diseases that make tomato production challenging in various parts of the world despite decades of conventional breeding and selection. Tomato is vulnerable to more than 200 diseases. As extensive cultivation of tomatoes continues, diseases caused by bacteria, soil borne fungi, seed borne and foliar fungi have increased even continuous improvement in strain variety [2]
