Abstract

A virus disease occurring in red clover and pea at the Viik Experimental Farm was found by means of plant inoculation tests to be caused by the pea mosaic virus. Infected plants grew slowly and overwintered poorly. There were variations in the frequency of the diseased plants in different red clover varieties.
