Maize resistance to ear rot caused by Aspergillus parasiticus

Abstract

The fungus Aspergillus parasiticus produces aflatoxins, the most important group of mycotoxins considering their potential toxicity that may cause cancer in humans. Prevention is the most important and economically most beneficial practice in the reduction of fungal growth and mycotoxin production. Due to that, the development of resistant maize genotypes is the most effective method. The aim of the present study was to analyse the resistance of maize hybrids to pathogenic and toxigenic A. parasiticus isolates originating from maize in Serbia. Hybrids used belong to three FAO maturity groups and showed a high level of resistance to A. parasiticus species. A combination of prevention management strategies and good grain management at harvest can lessen the impact of Aspergillus ear rot on yield and grain quality.
