 ABSTRACT

The present study was conducted to know the biocontrol potential of Trichoderma harzianum, T. asperellum and T. longibracheatum under in vitro conditions against some important chilli fungal plant pathogens namely- Alternaria alternata, A. solani, Curvularia lunata, Corynespora cassicola, Colletotrichum capsici, Choanephora cucurbitarum and Lasiodiplodia theobromae. The results revealed that T. harzianum showed its maximum antagonist efficiency than T. longibracheatum  and T. asperellum against  all test pathogens.  T. harzianum showed maximum inhibition against A. solani (84.12%) minimum inhibition was recorded against L. theobromae (52.94). Similarly T. asperellum  showed Maximum and minimum inhibition was obtained in case of C. cucurbitarum (81.76%) and L. theobromae (40.59) and also T. longibrachiatum showed Maximum and minimum inhibition was obtained in case of Choanephora (74.71%) and L. theobromae (48.24).

Key words:  Trichoderma harzianum, T. asperellum, T. longibrachiatum, test pathogens, per cent inhibition etc.
