Chickpea wilt caused by Fusarium oxysporum f. sp. ciceri is the most important soil borne disease and main constraint in boosting the yield. Keeping in view survey on the incidence of Fusarium wilt of chickpea diseases was carried out in seven districts of southern Karnataka during Rabi 2010-11.

Among different giant cultures evaluated for the growth and multiplication of pathogen, chickpea grain culture had highest F. oxysporum f.sp. ciceri population density of 78 cfu/gram of culture followed by chickpea straw (45 cfu/gram of culture).
