Maize kernels infestation by Fusarium spp. in the period 1996-1998 in Slovakia.
A three-year (1996-98) study on the occurrence of Fusarium ear rot on maize has revealed a high incidence of the disease in the maize fields in 21 localities of Slovakia. Contaminated ears were with obvious macroscopic symptoms (SK - symptomatic kernels) or without (AS - asymptomatic kernels) macroscopic symptoms. Productivity of SK decreased in comparison with AS, measured as a length of roots and shoots. The serious infestation occurred in 1998. The severity of infestation is not in linear relationship with precipitation. The following Fusarium species in particular cause the disease of maize: F. moniliforme [Gibberella fujikuroi] (up to 36%), F. proliferatum (up to 20%), F. subglutinans [Gibberella fujikoroi var. subglutinans] (up to 25.2%), F. graminearum [Gibberella zeae] (22.4%) and F. anthophyllum (7%). Other six species were found to occur irregularly at a low percentage (2 - 3.5%).
