Study on seed-borne nature of Alternaria alternata in chilli seeds indicated that in Standard blotter method, the incidence of A. alternata was to (average, ) and to (average, ) with unsterilzied seeds collected from general fields and diseased fields, respectively. The incidence for surface sterilized seeds from general and diseased fields were to (average, ) and to (average, ), respectively. In Agar plate method with Potato dextrose agar medium, the incidence of Alternaria alternata was to (average, ) and to (average, 18%) with surface sterilized. | Establishment of seed borne nature of Alternaria alternata causing alternaria leaf spot and fruit rot of chilli
