Abstract
Cured cocoyam corm discs were inoculated with Botryodiplodia theobromae, Fusarium solani, Aspergillus niger, Rhizopus stolonifer, and Sclerotium rolfsii and incubated at conditions favorable for infection.
The cut tissue did not heal rapidly to prevent rot.
Although 21 days of wound healing at 25–30°C abd relative humidity of 95–100% prior to inoculation were necessary to protect corms against infection by F. solani, A. niger, and R. stolonifer, only 14 days were required to protect corms against infection by S. rolfsii and B. theobromae. Would healing process was slightly affected by Dithane N45, sodium hypochlorite, benlate, and captan.
These chemicals had minor effects on normal wound healing.
Wound healing alone may not be sufficient to control rot of cocoyam corm tissue caused by the microorganisms but chemical treatment is recommended to provide protection until wound healing occurs.
