Cocoa yields in Côte d'Ivoire are low and falling each year, in part as a result of full-sun cropping systems. Thus, interest is now high in establishing sustainable cocoa agroforests through the re-introduction of shade trees. This article uses data collected from a sample of 400 cocoa farmers in the Soubré region of Côte d'Ivoire to rank the top alternative tree species of interest to farmers and to analyze the determinants of their presence and density in cocoa farms. Results show that the most significant determinants are: social network effects, ethnic group, and geographic zone. Also, poorer farmers and those in more isolated villages were more likely to associate their cocoa with crops popular for household consumption like oil palm. We thus suggest that future agroforestry programs should tailor the tree species promoted based on location, ethnic group, market access, and income level, and that extension programs should be designed to take advantage of networking effects.

“…(Wood and Lass, 1985;Wilson, 1999). Phythophthora palmivora occurs in all the six cocoa growing regions, but P. megakarya occurs mainly in the Ashanti, Western and parts of the Brong-Ahafo Regions (Akrofi et al, 2003). The fungus infects flower cushions, shoots, leaves, seedlings, roots and pods (Wilson, 1999).…”

“…Blackpod spores may be spread through rain splashes by vectors such as ants, and by wind, with the newly infected pods (covered with sporangia) acting as infection sources for up to 14 days (Wood and Lass, 1985). Husk pieces on the ground add infective material to the soil, while root infection is an important part of the annual cycle of the fungus (Wood and Lass, 1985;Akrofi et al, 2003); but farmers usually leave diseased pods and husks lying on the ground (Akrofi et al, 2003). In Ghana, yield losses due to P. palmivora are between 5 and 19% of annual output (Dakwa, 1984), while P. megakarya can cause as high as 100% loss (Dakwa, 1987).…”

Abstract. Many pests, especially capsid bugs, infest cocoa and contribute to low yields in producing countries. In Ghana, synthetic pesticides are recommended for controlling the insect pests, and a combination of synthetic pesticides and cultural practices for diseases and weeds. However, the farmers in Ghana are not motivated to adopt these recommendations due to the high cost of pesticides and low producer prices. There is also concern that use of synthetic pesticides on a wide scale can affect both human health and the environment. With the objective of improving cocoa yields through environmentally friendly pest control practices, evaluation of an integrated pest management (IPM) package based on aqueous neem (Azadirachta indica A. Juss.) seed extracts to control the insect pests and cultural practices to manage the diseases, weeds and parasitic plants was undertaken in farmers' fields with their active participation. The IPM package improved yields significantly and was found to be more profitable than the farmers' practices. However, there are two major constraints to adoption of the package by farmers: it is labour-intensive and currently, neem is not readily available to the community. The study recommends that these constraints must be tackled to motivate the farmers to adopt or adapt the IPM package.
