Nigeria cocoa farmers have been shown to react positively to price incentives (Helleiner, 1966; Oni, 1972; CBN/NISER, 1992). It is evident from past studies that Nigeria’s smallholder cocoa farmers have historically undertaken long-term measures to increase cocoa cultivation in response to remunerative producer prices (World Bank Report, 1973). This implies that the present price structure which has arisen as a result of the exchange rate policy and new marketing arrangement can in a like manner be relied upon to create an impact which will have favorable long-term ramification for cocoa cultivation and production. It is, however, suggested (Helleiner, 1966 and World Bank Report, 1973) that for the present price structure to have long term expansionary impact on cocoa cultivation and production, the farmers, assisted by government policy, and should adopt a number of improved cultural practices among which is an effective pest and disease control program. Baquet et al. (1976) also recognized that the decisions made relative to pest and disease control (although just a phase of an orchard management process) have a direct and significant economic effect on orchard production since if the crop is lost to disease(s), the decisions pertinent to orchard operation for the rest of the season may have limited or no effect on current year production.
