ANTAGONISTIC EFFECT OF TRICHODERMA STRAINS AGAINST FUSARIUM OXYSPORUM F. SR UDUM BUTTLER CAUSING WILTOF PIGEON PEA

摘要

The study revealed the antagonistic effect of Trichoderma spp. against the pathogen of Fusarium oxysporum f.sp. udum caused wilt disease of pigeon pea. Among all the bioagents, local isolate of Trichoderma viride (AI) was found to be the most promising showing maximum inhibitory effect on the mycelial growth (87.77%) of the pathogen. All bioagent were further tested as seed dressing agents for the control of wilt disease of pigeon pea. The lowest incidence of wilt (20.48%) was observed in the plots treated with local Isolates of T viride.
