摘要：Copper based fungicides are the only pesticide currently registered for use on cocoa for controlling Phytophthorapod rot in Nigeria. Black pod disease caused by Phytophthora megakaryaand P. palmivorais the most important and devastating disease of cocoa in Nigeria. Four candidates fungicides were evaluated for their effectiveness against black pod disease in threedifferent agro-ecological zones: Ibadan (Oyo State), Owena (Ondo State) and Ajassor (Cross River State). Ridomil Plus containing copper+metalaxl, Ridomil Gold containing copper+metalaxl-M, Funguran OH containing copper hydroxide and Champ D.P.also containing copper hydroxide were tested for their efficacy in a field trial. Compared with unsprayed plots, Ridomil Gold significantly reduced black pod infection from an average of 67.4% to in the first year to 19.7%. This pattern was similarly followed in thesecond year when percentage incidence of black pod infection was reduced to 12.7%. The other fungicides tested also reduced infection but to a lesser extent when compared with the performance of Ridomil Gold.
