References for reported resistance can be found here: https://agrilife.org/lubbock/files/2019/05/BtTraitTable-Citations.pdf

IR = refers to Integrated Refuge, where refuge hybrid seed has been pre-mixed with Bt hybrid seed in the bag.

Note: Herbicide tolerances listed are for the non-Integrated Refuge products.  IR products may have different herbicide tolerances and herbicide selection should be based on the properties of the refuge hybrid.
