Abstract
A wide range of fungi has been reported on yams in storage, often associated with deterioration. Post harvest fungicide treatments were found to give variable results. Thiabendazole and benomyl generally reduced levels of fungal infection and fresh weight losses in yam tubers but interacted with storage conditions, having less or no effect in ambient storage but large consistent effects in cold storage which encouraged fungal development. Thia-bendazole applications gave rise to low residue levels that would be acceptable in some other type of produce. Lim reduced tuber wastage but wrapping in diphenyl impregnated paper or dichloran treatment proved ineffective.
