Notes: Due to the widespread and regular nature of bollworm and budworm pest problems in cotton crops, GM IR areas planted are assumed to be equal to the area traditionally receiving some form of conventional insecticide treatment

South Africa, Pakistan, and Myanmar not included in analysis due to lack of data on insecticide use changes. Burkina Faso not included as not GM IR crop grown in 2020

Brazil: due to a lack of data, usage patterns from Argentina have been assumed
