BIORATIONAL INSECTICIDE ADOPTION AND CONVENTIONAL INSECTICIDE USE: A SIMULTANEOUS, LIMITED DEPENDENT VARIABLE MODEL

Abstract

Using data reporting section-level pesticide use for all of Arizona, this study estimates how early-season adoption of new biorational insecticides reduced subsequent broad-spectrum insecticide applications in cotton. The two-stage econometric model accounts for the endogeneity and censoring of the adoption intensity variable. One biorational application substituted for 3.66 broad-spectrum applications.Crop Production/Industries,
