Abstract:
Cumin (Cuminum cyminum L.), locally known as “Jeera” is an important and extensively cultivated spices crop. Diseases are the major constrain in economic crop production as they inflict heavy losses. Cumin is attacked by many diseases during seed germination to seed production and maturity. The present investigation was carried out on various pathological aspects to generate scientific information on this important pathological problem and to develop suitable management strategy to prevent losses due to root rot of cumin in in vitro. The six organic amendments at four different concentrations viz., 5, 10, 20 and 30 per cent were tested against M. phaseolina by poisoned food technique in in vitro. All the amendments were significantly inhibitory to M. phaseolina. Among them, maximum per cent growth inhibition of Macrophomina phaseolina was recorded by the extract of castor cake (85.62%) followed by cotton cake (75.53%) and mustard cake (71.26%).
