In vitro Potentiality of Native Trichoderma harzianum against Major Fungal Pathogens of Vegetable Crops

Vegetables like tomato (Solanum lycopersicum), brinjal (Solanum melongena), chilli (Capsicum annum), ridge gourd (Luffa acutangula) and cabbage (Brassica oleracea var. oleracea) are constantly incited by many fungal pathogens. So, Trichoderma harzianum a broad spectrum saprophytic fungal biological agent was used against various fungal pathogens of vegetables. A native Trichoderma harzianum was isolated from the tomato rhizosphere and was subjected for in vitro studies. A total of nine different fungal pathogens of vegetable crops were selected for interaction studies by dual culture technique. The results showed that, native T. harzianum is effective against all fungal pathogens.
