Features of allelopathy between fusarium species and concomitant Trichoderma longibrachiatum in the maize rhizosphere in Kuban

Abstract

The purpose of these studies was to study the interaction of pathogens of corn root rot in the agricultural sector of the Northern region of Krasnodar region. Corn root rot in the agricultural farms of the region annually cause significant damage to the harvest of silage and corn grain. In the course of research, the biological feature of the relationship between two species of the genus Fusarium: Fusarium concentricum Nirenberg & O'donnell and Fusarium proliferatum Matsush., optimizing the five-fold increase in the first species of mushroom compared to the growth of the second. PCR analysis revealed Fusarium oxysporum strain IMI 58289 with increased ability to exhibit elements of aggressive synergism. These fungi belong to the Department Ascomycota, order Hypocreales. In the soil of the studied rhizosphere, a natural hyperparasite – Trichoderma was detected, which can be used to minimize Fusarium infection.
