Tomato Bunchy Top

  • T. O. Diener
Part of the The Viruses book series (VIRS)


The tomato bunchy-top disease is known to occur naturally only in South Africa (McClean, 1931). Characteristic symptoms are severe stunting of the entire plant, in particular the production of small leaves, a necrosis of the leaves and stems, and various forms of leaflet distortion, such as curling and an abnormal unevenness of the surface (McClean, 1931). Chlorosis or mottling are not features of the disease.
