First report of Fusarium falciforme affecting common bean (Phaseolus vulgaris) in Cuba.

Abstract

Common bean (Phaseolus vulgaris) is affected by a range of soil pathogens that reduce the yield following root infection. Fusarium species are among the most significant pathogens and infection may reduce yields by up to 50%. During the 2015-16 harvest, samples of wilting bean plants (P. vulgaris cv. Cuba Cueto 25-9), which had brown necrotic roots, necrosis of the stem base and leaf chlorosis, were taken to the laboratory from fields in Tapaste, Mayabeque Province, Cuba. Based on the results of morphological observations, sequence analysis of the translation elongation factor 1-a gene and pathogenicity test, the causal agent was identified as Fusarium falciforme. This is thought to be the first report of F. falciforme affecting P. vulgaris in Cuba.
