Investigations on the fungal populations associated with banana leaf spot diseases in Guangxi
Investigations on banana leaf spot fungal pathogens were conducted in major banana production areas in Guangxi between February and March in 2009. The results showed that at least 10 fungal pathogens were found in the banana leaf spot samples. Cordana musae was the most frequently observed fungal pathogen with a detection rate of 56.77%-92.19% in the samples. Corynespora cassiicola and Deightoniella torulosa were mainly observed in the samples collected from the plantations at Nanning City, with the detection rates of 32.34% and 22. 61%, respectively. The banana leaf spots with only a single pathogen were predominant (78.13%-92.19%) compared to those with two or more fungal pathogens.
