Abstract
A survey was conducted in 2010-2011 rabi cropping season to obtain information on the distribution and incidence of chickpea diseases in respect to soil type, cultivar used, seed treatment in central and southern parts of India. Local cultivars predominated in most farmers’ fields (25% - 48%). 63% of the farmers were practices seed treatment with fungicide. Dry root rot and collar rot diseases were found at all of the sites and incidence ranged from 8.9% - 10.3% and 7.1% - 10.5% respectively irrespective of cultivar type and locations. Incidence of wilt and black root rot disease ranged from 9.7% - 13.8% and 6.6% - 7.4% respectively. Black root rot disease was found in Andhra Pradesh and Karnataka states only. The result indicated that dry root rot and collar rot is currently highly distributed in all surveyed chickpea growing areas of central and southern parts of India. Therefore, possible management options are vital to alleviate the problem.

Summary
Chickpea (Cicer arietinum L.) is the most important pulse crop and India accounts for approximately 75% of world’s chickpea production It occupies an area of 8 mha and its production is 7.1 mt with an average productivity of 885 kg·ha−1 (Economic survey 2009-2010). A number of improved chickpea diseaseresistant varieties have been multiplied and disseminated to farmers in many districts of India Their current prevalence in farmers’ fields has not been documented. Wilt is the major diseases occurs in all chickpea growing areas of the Indian sub-continent [7], recently dry root rot and collar rot emerging as a major threat to chickpea production [6] These diseases have become more important in recent years due to drastic climate change makes the crop more susceptible [6]. The objectives of the survey were: 1) to find out the occurrence and distribution of chickpea diseases; 2) to find out the incidence of the diseases; 3) to assess the levels of resistance and susceptibility of the cultivars grown in farmers’ fields
