Bt Cotton — Prelims Strategy

Prelims Strategy

For Prelims, focus on factual accuracy and conceptual clarity regarding Bt cotton. First, understand the 'what' and 'how': What is Bt cotton? How does it work (Cry proteins, *Bacillus thuringiensis*, molecular mechanism)?

Second, identify the key players: Which regulatory body (GEAC) approves it? What are the roles of RCGM and DBT? Third, grasp the core benefits (bollworm resistance, reduced pesticide use) and major challenges (pink bollworm resistance, high seed costs).

Pay close attention to keywords like 'refuge strategy' and its purpose. Memorize the specific Cry genes (Cry1Ac, Cry2Ab) and their target pests. Practice MCQs that test your understanding of the differences between Bt and conventional cotton, and the specific pests targeted.

Vyyuha recommends creating flashcards for key terms, regulatory bodies, and their functions. Also, stay updated on recent developments, especially regarding new approvals or resistance issues, as these are frequently asked in current affairs sections.
