The wonder crop pigeonpea is renowned for its multipurpose uses. India alone covers more than 70% area (4.65 M ha) among all pigeonpea growing countries (FAOSTAT, 2015). The crop suffers from numerous pathogens, but fortunately, only a few of them cause huge losses (Kannaiyan et al., 1984) (mehtashv). Among the soil borne diseases Fusarium wilt causes considerable yield losses to the pigeonpea in India as well as in major pigeonpea growing areas of Karnataka especiallyNorth Eastern Karnataka. On that note survey was conducted during the three consecutive years 2017, 2018 and 2019 in the major pigeonpea growing districts of Raichur, Kalaburgi, Yadgir and Bidar districts to know the incidence of disease. During the year 2017-18 the highest Fusarium wilt incidence was noticed in Kalaburagi (21.1 %), followed by Raichur (16.67 %) and Yadgir district (7.7%). On contrary, lowest wilt incidence was observed in Bidar district (3.5%). While during 2018-19 the district mean severity among the di

Pigeonpea, Fusarium, Survey, Resistant, Susceptible

The survey conducted across the locations and seasons revealed the maximum Fusarium wilt incidence was recorded in Kalaburagi district followed by Raichur district whereas Bidar district has recorded the minimum wilt incidence. Monocropping has been practiced in the villages pertaining to Kalaburgi district also Fusarium wilt incidence is generally more in farmer’s field with the local cultivars such as, Kari togari, Gulyal local and Kattibheeja as compared to improved cultivars. In addition cultivar Asha is considered to be a very good resistant source against Fusarium wilt across the four surveyed districts. Where as in some villages belonging to Bidar the intercropping of pigeonpea with other crops like sorghum, horsegram, blackgram etc., majority of the pigeonpea crop was grown under vertisoils compared to alfisols. The variations in the diseases incidence in different locations may be because of the impact of the environmental factors or variation in the resistance of the cult
