ANTAGONISTIC EFFECT OF TRICHODERMA STRAINS AGAINST FUSARIUM OXYSPORUM F. SP. UDUM BUTTLER CAUSING WILT OF PIGEON PEA
1Bhargava Agriculture Laboratory. Department of Botany,
University of Allahabad, Allahabad - 211 002, India
ABSTRACT
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
