Refuge Requirements for Cotton-Growing Areas

In the cotton-growing areas shown on the bottom of this page, there are special refuge requirements for B.t. Corn Borer corn, as follows:

  • On each farm, plant up to 50 percent of corn acres with B.t. Corn Borer corn. Plant a minimum of 50 percent of corn acres with non-Bt corn. The non-Bt corn can be treated with insecticides only when the level of pest pressure meets or exceeds economic thresholds. Sprayable Bt insecticides must not be applied to non-Bt refuge corn.
  • Plant the non-Bt corn refuge within, adjacent to, or near the B.t. Corn Borer fields.
  • Plant the refuge (non-Bt corn) within, adjacent to, or near B.t. Corn Borer fields. The refuge must be placed within 1/2 mile of the B.t. Corn Borer field (1/4 mile or closer preferred)
