Analysis of microbial taxonomical groups present in maize stalks suppressive to colonization by toxigenic Fusarium spp.: a strategy for the identification of potential antagonists

Autor: Köhl, J. Lombaers, C. Moretti, A. Bandyopadhyay, Ranajit Somma, S. Kastelein, P.

Pink ear rot of maize caused by Fusarium verticillioides, Fusarium proliferatum and Fusarium graminearum can lead to severe yield losses and contamination of grain with a range of mycotoxins. Maize stalks colonized by Fusarium spp. are the main primary inoculum source for Fusarium incited epidemi...
