Abstract
The control of Phytophthora pod rot disease in Nigeria is largely through the use of copper-based fungicides. Majority of Nigerian cocoa farmers still use copper sulphate for Phytophthora pod rot control despite the introduction of more efficacious fungicides that have metalaxyl in the past decade. This calls for the continuous evaluation of the various brands of copper sulphate in the Nigerian market.the field study in 2003 and 2004 reports on the efficacy of Nispra 1 Tismac 2 Kopesra3 Mistai 4 and Mag 5 which are brands of copper sulphate on the control of Phytophthora pod rot disease of cocoa. Mistai 4 gave the lowest percentage pod rot control 52.9 while the highest control 69.4 was achieved with Tismac 2 compared with the unsprayed cocoa plots. The yield of cocoa was related to the degree of control of black pod disease. Thus the efficacy of Tismac 2 recommends its continued use by the peasant cocoa farmers in Nigeria who can not afford the recently introduced fungicides.
