Yam anthracnose in Barbados: the current status
1991
Green, K.R. (Caribbean Agricultural Research and Development Inst., St Augustine (Trinidad and Tobago)) | Simons, S.A.
A survey was undertaken to monitor the severity and spread of anthracnose (casual agent Colletotrichum gloeosporioides penz.) on yams (Dioscorea alata) of the variety White Lisbon at eight field sites in Barbados throughout the 1990 - 1991 growing season. Disease progress curves show that there were considerable differences in the rate of disease development among sites. These differences are discussed in relation to environmental conditions, the application of fungicides and the subsequent yield of tubers from sample plants. Investigations into the survival of C. gloeosporioides between growing seasons showed that the fungus was present in the skin and flesh of tubers but was not isolated from soil
