The refuge deployment for Bt-cotton will undergo a sea change from the planting season of 2020. Stepping back, the Genetic Engineering Appraisal Committee (GEAC), Ministry of environment, Forest and Climate Change, Government of India (GoI) had approved the first transgenic single-gene Bt-cotton hybrids in India in 2002 and the next-generation cotton transgenics with stacked Bt genes (Bollgard II®) in 2006, and had recommended sowing of 20% area with non-Bt cotton as ‘structured’ refuge for both types of Bt-cotton. Over time, refuge planting became voluntary and cotton farmers ignored planting of refuge to maximize their returns from a field of 100% Bt-cotton.
