Evaluation of a Blended Refuge for Corn Rootworm

The purpose of this study was to evaluate the effectiveness of the blended refuge concept against corn rootworms. The treatments evaluated include a pure stand of Herculex XTRA (HXX), a pure stand of Roundup Ready 2 (RR2), a pure stand of RR2 with Force 3G applied overtop, and two treatments with the refuge in a bag concept–one with 95 percent HXX and a 5 percent RR2 blended refuge and the other with 90 percent HXX and a 10 percent RR2 blended refuge.
