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 root rot disease was found more severe proportion on popular varieties of cumin viz., GC-4, GC-2 and local in three district of northern Gujarat viz. Banaskantha, Patan and Mehsana. The highest mean per cent disease incidence was observed in the Patan district (35.55%). The tissue isolation from stem and root of infected plant revealed the association of Macrophomina sp. which was identified after purification and cultural and morphological studies and found that it was Macrophomina phaseolina.
