EXPLANATION
Biological Pest, Disease & Weed Management in
- Organic Management of Red Pumpkin Beetle (Aulacophora foveicollis):
- Early Sowing: Sowing cucurbit seeds in November–December (under riverbed/polythene covers) or early February allows plants to advance beyond the vulnerable seedling stage before beetles emerge from winter hibernation.
- Deep Summer Ploughing: Exposes soil-inhabiting pupae and overwintering adult beetles to desiccation and predatory birds.
- Clean Cultivation: Eradicates alternative weed hosts and crop residues.
- Grafting on bottle gourd (D) is ineffective because bottle gourd (Lagenaria siceraria) is a favored host of Aulacophora.
- Correct Option: Option 2 ((A), (B) and (C) only).
