‘Dry Skin’ or dry rot in yams is a disease found wide-spread in Barbados on the yam cultivars currently being grown here and indeed on nearly all the varieties of Dioscorea spp.
The causal agent is a nematode, Pratylenchus coffae which seems to work in association with a fungal organism and the disease causes both quantitative and qualitative damage to harvested tubers. (Brathwaite & Hutton, 1980)
