Effect of Trichoderma species on growth of Fusarium proliferatum and production of fumonisins, fusaproliferin and beauvericin

Trichoderma species has been suggested as potential biocontrol agent for Fusarium verticillioides on maize. In this cereal, F. verticillioides and F. proliferatum contributed to fumonisin accumulation. In addition, F. proliferatum could produce beauvericin and fusaproliferin. The aim of this work wa...
