IPM programs have expanded in both central and South America over the past ten years. The South-American program has been focused in the Andean region, especially on potatoes and fruits, and has been led in part by the IPM CRSP, the International Potato Center (CIP), and The International Center for Tropical Agriculture (CIAT) in conjunction with national agricultural research systems (NARS). Central American IPM has focused on non-traditional agricultural export crops, especially fruits and vegetables. The IPM CRSP has centered its regional IPM programs in Ecuador and Guatemala. In this chapter, we turn our attention first to the Ecuador program and then to Guatemala.
