Resumen
Descripción
Using data envelopment analysis with principal components, we calculate an adoption-intensity
index for herbicide-resistance best management practices (BMPs). Empirical results for over
1,100 farmers in twenty-two U.S. states suggest that many farmers could improve their herbicideresistance
BMP adoption. Two-limit truncated regression results show that higher yields and a
greater proportion of acres planted with Roundup Ready
R seeds motivate weed BMP adoption.
While soybean and corn farmers have lower adoption intensity than cotton farmers, farmer
educational attainment and greater concern for herbicide effectiveness and for human and
environmental safety are found to help increase the adoption of weed BMPs.
