Fungal disease problems of chickpea and pigeonpea in India have been properly identified and their distribution and importance determined. Fusariurn wilt, dry mot rot, ascochyta blight, botrytis grey mold, and collar rot aro the major diseases affecting chickpea. In pigeonpea, fusarium wilt, phytophthora blight, and ahernaria blight are important diseases. In the c~sosf chickpea wilt, much progress has been made in both unc'srstanding the problem and its managernont through resistant varieties. Prqress on dry root rot is limited to identification of a few field tolerant sources. Though work on ascochyta blight has been going on forseveralyears, progress on its management has not been satisfacfoty mainly due to lack of stable'resistance sources. Effective seed dressing and foliar fungicides have been identified but there are limitations in their use. A few field- tolerant iinas have been identified and some informatim on pathogenic variability and genetics of resi'slance has bsen obtained. Some effec:ive seod dressing and foliar fungicides have been found effective in controlling botrytis grey mold. in pigeonpea, excellent progress has been made in tho management of wilt, especially fhrough host-plantresistance. Theprogress on the managementofphytophthora blight through host-plant resistance has been limited mainly bo&use of frequent change in the virulence of the pathogen. Some field-tolerant lines have been identifiedand seed dressing and foliar sprays with metalawyl were found to pmvide good control. Good progress has been made in the managernont of alternaria blight through utilisation of host-plant resistanca.
