Effects of agrochemical treatments on the occurrence of fusarium ear rot and fumonisin contamination of maize in southern Italy.

Abstract

The efficacy of agrochemical treatments, based on three different fungicides combined with an insecticide,was tested in southern Italy for two years on three maize hybrids to control Fusarium ear rotof maize and the accumulation in the maize kernels of the carcinogenic mycotoxins fumonisins. Insectdamage incidence and severity, disease incidence and severity, identification of Fusarium species andlevels of fumonisin contamination in kernels were determined. Field trials showed in both years thatnatural colonization of maize kernels by the fumonisin producing species Fusarium proliferatum and F.verticillioides (up to 81.5 and 26.5%, respectively) and total fumonisin contamination (up to 68.2gg-1)were highly severe. For all hybrids and in both years, the treatment with the insecticide applied alonereduced the insect damage severity consistently and the content of fumonisins in the kernel only in halfof the cases, whereas fungicide treatments applied in combination with the insecticide showed a furthersignificant reduction of fumonisin contamination in the three hybrids and in both years.
