Evaluation of Bio-control agents against three common Fungal pathogens
ABSTRACT
Three species of Trichoderma viz. Trichoderma viride, Trichoderma harzianum and Trichoderma virens were evaluated for their antagonistic potential against Fusarium oxysporum, Colletotrichum gloespoiroides and Phomopsis vexans isolated from strawberry, guava and brinjal respectively. In vitro results revealed that all the three bio-control agents inhibited the growth of Fusarium oxysporum by 55.38 to 72.38 %, Colletotrichum gloeospoiroides by 44.5 to 49 .2% and Phomopsis vexans by 39.0 to 69.34% due to the production of non volatile substances.
