Abstract

EFFECT OF CULTURE FILTRATE OF ISOLATES OF TRICHODERMA SPECIES ON MYCELIAL GROWTH INHIBITION OF FUNGI CAUSING ROT OF TOMATO AND BRINJAL

Jahangir Abdullah Koka*, Abdul Hamid Wani and Mohd Yaqub Bhat

ABSTRACT

The present study was carried out to know the efficacy of culture filtrates of Trichoderma species in managing the rot causing fungi of tomato and brinjal under in vitro conditions. It was observed from the study that all the concentrations of culture filtrates brought about significant inhibition in mycelial growth of all rot causing fungi. However, highest inhibition was observed at higher concentrations followed by lower concentrations of culture filtrates of antagonists. It was revealed from the present study that all the concentrations of isolates of Trichoderma species showed antimycotic activity against rot causing fungi. Culture filtrate of all the three isolates of Trichoderma species showed maximum activity against Aspergillus niger at highest concentration followed by Penicillium expansum, Mucor plumbeus and least activity was shown against Alternaria alternata respectively. The inhibition in mycelial growth increased with the increase in the concentration of culture filtrate of isolates of Trichoderma. It was further revealed from the results that the culture filtrate of Trichoderma harzianum isolate (PPT1) showed maximum inhibition in mycelial growth against Trichothecium roseum and least inhibition against Rhizoctonia solani at higher concentrations of culture filtrate. However, culture filtrate of Trichoderma viride isolate (PPT2) showed maximum mycelial growth inhibition against Rhizoctonia solani and against Penicillium chrysogenum and least inhibition against Trichothecium roseum at highest concentration respectively. Likewise, culture filtrate of Trichoderma virens isolate (PPT3) showed maximum inhibition against Rhizoctonia solani at higher concentration of culture filtrate of Trichoderma and least inhibition against Penicillium chrysogenum at the same concentrations respectively.
