Biocontrol Effect of Trichoderma harzianum on Selected Fungal Pathogens by Dual Plate Method

Abstract

Fungal pathogens pose a significant threat to various crops, leading to substantial economic losses and food safety concerns. Among these, Aspergillus flavus, Aspergillus fumigatus, Aspergillus niger, Aspergillus parasiticus, Cladosporium, Macrophomina phaseolina, and Penicillium are notorious for their pathogenicity and mycotoxin production. This study investigates the biocontrol potential of Trichoderma harzianum against these fungal pathogens using the dual plate method. Trichoderma harzianum is a well-known biocontrol agent with the ability to inhibit the growth and development of various phytopathogens. In this research, we explore the antagonistic activity of Trichoderma harzianum against these fungi and its impact on their growth and mycotoxin production. The findings of this study contribute to the development of eco-friendly and sustainable strategies for managing fungal pathogens in agricultural and industrial settings.
