Adoption of transgenic corn resistant to corn rootworm (CRW corn) was analyzed using a probit model with data from a survey of Indiana producers. Operator age, farm size, and regional and self-reported measures of rootworm pressure were all statistically significant in explaining adoption. In addition to these typical explanatory variables, market access variables, price variables, and insect resistant management plan requirements were very significant. These findings suggest that the value of CRW corn to the producer is strongly influenced by the fact that it is not yet fully approved for sale in Europe.

Key words: Corn rootworm corn, probit model, technology adoption.
