| Potato farmers in Ecuador rely on chemical inputs to manage pests and optimize yields. Integrated pest management techniques lower production costs, reduce pesticide exposure, and improve long-term agricultural sustainability. Public extension does not, however, exist in Ecuador and cost-effective means of communicating complex messages to producers are needed. We analyze cost-effectiveness of alternative dissemination methods, including farmer field schools (FFS), field days, pamphlets, and word-of-mouth transmission. Field days and pamphlets have strong impacts on adoption, especially considering their low costs. FFS are effective, but expensive. Evidence also indicates significant diffusion from FFS to non-FFS farmers, indicating high... |

| Agricultural development is essential for improved well-being in rural Ecuador. As much as 40% of the population relies on agriculture as its primary source of income and agricultural exports account for a significant proportion of foreign exchange revenue. In the highlands, potatoes are a major staple, and more than 90,000 producers grow them on about 60,000 hectares of land. Potato production is associated with heavy use of chemical inputs--pesticides and fertilizers--to manage pests and optimize profits. Concerns have emerged about the sustainability of Ecuador's potato crop as rising input costs have created a cost squeeze and public health officials are increasingly concerned about health consequences of pesticide over use. Producers need... |
