Four fungal bio-control agents, viz., Trichoderma harzianum, T. viride, Aspergillus and Tricothecium were evaluated invitro through dual culture technique against Fusarium oxysporum f. sp. ciceri, the causative agent of wilt of chickpea and Ascochyta rabiei, the causative agent of Ascochyta blight of chickpea. The observations were taken after fourth and seventh day for both the pathogens. After fourth day, observations recorded in case of Fusarium oxysporum f. sp. ciceri, the minimum colony diameter (1 cm) and maximum inhibition percentage over control (85.71%) was observed in Trichoderma harzianum which were statistically at par with T. viride, Aspergillus and Tricothecium while after seventh day, the result was more or less similar. The minimum colony diameter (1.2 cm) of pathogen was observed in Trichoderma harzianum with maximum inhibition per cent (86.66%) over control, which differed statistically from T. viride, Aspergillus. Tricothecium showed least effectiveness against the target pathogen showing colony diameter (4.1 cm) and inhibition (41.42%) after fourth day and colony diameter (4.6 cm) and inhibition (48.88%) after seventh day over control. After fourth day, the observations taken in case of Ascochyta rabiei, the minimum colony diameter (0 cm) and maximum inhibition per cent over control (100%) were observed in T. harzianum and T. Viride which were statistically at par with Aspergillus and Tricothecium. After seventh day the result was more or less similar. The minimum colony diameter (0 cm) of pathogen was observed in T.harzianum and T. viride with maximum inhibition percentage (100%) over control, which differed statistically from Aspergillus. Tricothecium showed least effectiveness against the target pathogen showing colony diameter (1 cm) and inhibition per cent (66.66%) after fourth day and colony diameter (1.2 cm) and inhibition per cent (82.85%) after seventh day over control.
