Abstract

Seven Trichoderma isolates were screened for their bio-efficacy against Phytophthora dresceleri. Dual culture test revealed that all the bio-agents significantly inhibited the mycelial growth of the pathogen with maximum (65.9%) inhibition by Trichoderma isolate (1) (pigeon pea isolate) rhizosphere isolate, improving the growth of plant (vigour index-1092.8%) and disease incidence (2.0%).
