With only 4% of farmers formally trained in pesticide use or handling, and over 87% openly admitting to using little or no protective measures while applying pesticides, overuse is potentially a great threat to farmer health as well as the environment. Pesticide overuse was initially modelled using a three‐equation, trivariate probit framework with health effects and misperception of pesticide risk as endogenous dummy variables. Significance tests revealed that health and misperception were not endogenous to overuse, suggesting a bivariate probit model for health effects and misperception and a separate probit model for…
