Option 1 – Embedded Refuge

At least one row of non-Bt refuge cotton must be planted for every six to 10 rows of WideStrike^® Insect Protection cotton. The refuge may be treated with sterile insects, any insecticide (except Bt foliar spray products) or pheromones labeled for the control of pink bollworm, but only if the entire field is similarly treated. The in-field refuge rows must not be treated independently of the surrounding WideStrike cotton field in which they are embedded, and the refuge rows must be managed identically to the WideStrike cotton rows. One way the interspersed rows can be planted is by putting the non-Bt cotton variety in one hopper on the seed planter and WideStrike cottonseed in the remaining hoppers. The interspersed refuge approach is not allowed outside of the western Cotton Belt.
