What impact has Bt cotton had on smallholder farmer livelihoods and pest management practices in African countries where it’s been introduced?
Bt cotton is self protecting against the damaging bod borer pests that otherwise decimates cotton yields up to 100 percent. Adoption of Bt cotton has had the advantage therefore of ensuring that the maximum yields of the crop have been realized. In addition, the farmers save on the costs they would have used in the more than 12 spray rounds that they would apply on non-Bt cotton. With Bt cotton, farmers now only apply 2 to 3 rounds of spray against other important pests such as mealy bugs.
