Abstract
In a recent study, a population of Fusarium strains isolated from maize, closely related to F. subglutinans, was described as a new species, Fusarium temperatum J. Scauflaire et F. Munaut. In several temperate regions of Europe, the F. temperatum:F. subglutinans ratio is very high in the fields, suggesting that F. temperatum competes with its sister species F. subglutinans. This raised the question of the contribution of this novel species to the final ear rot or stalk rot symptoms observed on maize plants at harvest, as well as to the potential mycotoxin contamination. The pathogenicity of F. temperatum to maize plant has been tested in greenhouses and preliminary results confirm its ability of to cause stalk rot and seedling malformation with a virulence similar to that of F. subglutinans. Currently, studies are in progress to elucidate the mycotoxigenic potential of F. temperatum.
