Biopesticides — Prelims Strategy

Prelims Strategy

To ace Prelims questions on biopesticides, aspirants must focus on factual accuracy and conceptual clarity. Begin by thoroughly understanding the definition and classification of biopesticides (microbial, botanical, biochemical, semiochemicals) with specific examples for each.

Memorize the key organisms (*Bacillus thuringiensis*, *Trichoderma spp.*, NPV, neem) and their primary modes of action. Pay close attention to the advantages (specificity, environmental safety, residue-free) and disadvantages (shorter shelf-life, variable efficacy).

Crucially, know the regulatory bodies like CIB&RC and GEAC and their roles. Practice identifying correct and incorrect statements, as UPSC often uses multiple-choice questions that test nuanced understanding.

Create flashcards for key terms and examples. Understand the difference between biopesticides and chemical pesticides, as this is a common area for trap questions. Link biopesticides to government schemes like NMNF and PKVY, as current affairs are frequently tested.

A strong grasp of these core facts will enable you to navigate complex options and avoid common pitfalls.
