EFFICACY OF TRICHODERMA SPP, AND RHIZOBIUM-MELILOTI IN THE CONTROL OF
ROOT-ROT OF FENUGREEK
HAQUE SE; GHAFFAR A
Abstract: Trichoderma viride, T. hamatum and Rhizobium meliloti used as seed
dressing and or as soil drench reduced Macrophomina phaseolina infection
by more than 50% on 30 day old fenugreek seedlings. Combined use of T.
koningii and R. meliloti showed better control of M. phaseolina
infection on both 30 and 60 day old plants. T. harzianum, T. hamatum, T.
pseudokoningii and R meliloti (KUMH 555 & KUMH 653) used either as seed
dressing and or as soil drench completely controlled the infection of
Rhizoctonia solani both on 30 and 60 day old plants. Combined use of T.
viride and T. koningii with rhizobia were also found effective. T.
harzianum, T. koningii alone or R. meliloti used with T. viride, T.
hamatum, T. koningii and T. pseudokoningii completely controlled the
infection of Fusarium spp., on 30 day old seedlings, while in 60 day
old-plants more than 50% reduction was found by Trichoderma spp., and R.
meliloti used alone or rhizobia mixed with Trichoderma spp., when used
either as seed dressing and or as soil drench.
