ENVIRONMENT DEVELOPMENT AND SUSTAINABILITY(2023)
摘要
Bt cotton has played a great role in bollworm management since its approval for commercial cultivation in India. To ensure the longevity of Bt technology, structured refuge was advocated wherein, the non-Bt seeds were provided as separate pack along with Bt seeds.

This strategy ensures automatic compliance of refuge, since a prescribed range (5–10
