Viral diseases of cardamomum (Elettaria cardamomum Maton) and their management

Abstract

Small cardamom (Elettaria cardamomum Maton) is affected by many diseases which have been identified as a major production constraint. Among the viral diseases ‘katte’ or mosaic is the major viral disease causing severe yield losses to an extent of 68 per cent. In addition, Nilgiri necrosis, infections variegation virus and ‘kokke kandu’ diseases are gaining importance in recent years. The present paper reviews the information available on distribution of viral diseases, symptomatology, crop loss, transmission, etiology, host range and disease management. The future plan of work on aspects such as breeding for disease resistance through genetic engineering, virus characterization and early detection methods are indicated.
