Katyayani Bt Bio Larvicide is a powder bio-insecticide containing Bacillus thuringiensis. It controls a wide range of insect larval pests through ingestion, disrupting the larvae's gut, causing them to stop feeding and eventually die.

Target Pests:

• Tobacco Caterpillar
• Corn Borer
• Stem Borer
• Fruit Borer
• Pod Borer
• Shoot Borer
• Rice Leaf Roller
• Leaf-Eating Caterpillar
• Cotton Bollworm
• Cotton Bridgeworm
• Tea Caterpillar
• Lepidoptera, Hymenoptera, Diptera, Coleoptera pests like Tea Looper, Pine Caterpillars, and Spiny Moths

Target Crops:

• Cotton
• Paddy
• Cabbage
• Chickpea
• Okra
• Tomato
• Cauliflower
• Chilli
• Gram
• Pigeon Pea
• Soybean
• Tobacco
• Castor
• Teak
• Red Gram
• Other crops

Mode of Action:

1. Spore Ingestion: Insect larvae ingest Bt spores present on plant material.
2. Spore Activation: The alkaline environment in the insect's gut dissolves the spores, releasing protein crystals.
3. Protoxin Activation: Gut enzymes convert these crystals into active Bt toxins (Cry toxins).
4. Binding: Toxins bind to specific receptors on midgut epithelial cells.
5. Pore Formation: Toxins form pores in the cell membrane.
