Abstract
This article examines the impact of two Integrated Pest Management information dissemination approaches on insecticide use and efficiency of Vietnamese rice farmers. Specifically, we investigate the impact of Farmer Field Schools (FFS) and No Early Spray (NES) mass media campaigns by utilizing econometric approaches that control for endogeneity and selection problems. Our results suggest that farmers exposed to FFS and NES information are more technically efficient than control farmers who have not been exposed to information from FFS or NES. However, only FFS farmers, not NES farmers, seem to have significantly reduced their insecticide use relative to non-FFS or non-NES control farmers.
