Adoption Analysis and Impact Evaluation of Potato IPM in Ecuador

Abstract

dc:description.abstract

There are several well-known negative side effects associated with pesticide use such as health problems and environmental pollution. Integrated Pest Management (IPM) seeks to minimize pesticide use while reducing pest infestation to economically tolerable levels. The introduction of IPM CRSP activities in Ecuador to institutionalize IPM methods focused on priority crops in the country. This study analyzes adoption and the economic impacts of IPM technologies on potato production in the province of Carchi. A model is estimated in which IPM adoption is discrete and ordered and pesticides expenditures are estimated as a function of education, farming experience, wealth, plot size and farmer being sick due to pesticide use for each level of IPM adoption. Results indicate that farmers who were exposed to certain IPM information sources increased adoption of IPM practices on potatoes, but farmers\' education and experience were not important factors in explaining IPM adoption. The calculated economic benefits in terms of aggregate cost savings per production cycle were $823,000.
