Abstract:

The cluster bean (Cyamopsis tetragonoloba L.Taub.) also known as Guar is one of the most important commercial crop and major source of guar gum. The clusterbean is affected by various fungal diseases. Among those dry root rot caused by Macrophomina phaseolina (Tassi) Goid., a soil borne, cosmopolitan fungus infecting cluster bean and more than 500 plant species. The first symptom of disease is yellowing of the leaves, dark lesion may be seen on the bark at the ground level, the basal stem & main root may show dry rot symptoms. The antagonistic activity of five bioagents was evaluated against M. phaseolina in vitro and the maximum mycelial growth inhibition of M. phaseolina was recorded by Chaetomium globosum (68.14%), followed by Bacillus subtilis (67.03%), while least mycelial growth inhibition was recorded in P. florescence (14.81%). The inhibitory effect of eight fungicides was also tested at 100, 200 and 300ppm concentration by poison food technique, after 24 hrs of inoculation the complete inhibition of mycelial growth was found with all fungicides at all three concentration. The seven fungicides Mancozeb, Carbendazim, Saaf, Topsin-M, Tebuconazole, Hexaconazole and Propiconazole completely inhibited the mycelial growth of pathogen at 200 and 300ppm concentration.
