September 2010


Bladder dock (Rumex vesicarius L.) is an important biennial bushy vegetable in southern India. The young leaves have a piquant flavor and sour taste, and are eaten boiled or raw in salads. The dried roots are ground into powder and used to treat diarrhoea and bleeding. To our knowledge, this is the first report of Pseudoperonospora rumicis on R. vesicarius in India. Pseudoperonospora rumicis is the second downy mildew pathogen recorded on Rumex vesicarius and is of potential concern to Rumex growers.
