The Economics and Efficacy of Bt-RW Corn: After 20 Years, What Have We Learned?
Corn rootworms have long been the key pest of corn in Indiana and throughout the corn belt. Bt hybrids targeting this pest complex were first introduced in 2004 and have been rapidly and almost completely adopted by producers. This presentation focuses on measuring how these traits have fared in the years since, and how pest pressures have changed and evolved in response to continuous Bt corn use.
