Abstract

Rhizoctonia solani Kuhn [= Corticium solani (Prill. et Del.) Bourd. et Ganz.] and Colletotrichum coccodes (Wallr.) Hughes [= C. atramentarium (Berk. et Br.) Taubenh.] were considered to be contributing factors of 'potato sickness' in the United Kingdom (Cheal, 1929; Edwards, 1929; Triffitt, 1931). Miles (1930) while considering R. solani to be a contributory factor disregarded C. cocco des to have any role. However, Millard et al. (1932) did not support this view. Dunn and Hughes (1964) did not find any synergistic effect between the potato cyst eelworm (Heterodera rostochiensis Woll.) (PCE) and C. coccodes. Greater reduction in the growth of potato and tomato in the presence of both R. solani and PCE than PCE alone was observed by Grainger and Clark (1963) and Dunn and Hughes (1964), respectively.
