Katyayani Bt Bio Larvicide: Natural Insect Control Solution
Katyayani Bt Bio Larvicide is a bio insecticide in powdered form, containing the naturally occurring Bacillus thuringiensis bacterium. This powerful larvicide targets a broad range of insect larvae through ingestion. Upon ingestion, the Bt spores disrupt the larvae's digestive system, causing internal tissue damage, cessation of feeding, and death of the pest.
Target Pests
Katyayani Bt Bio Larvicide effectively controls various larval pests, including:
- Lepidoptera: Tobacco caterpillar, Corn borer, Stem borer, Fruit borer, Pod borer, Shoot borer, Rice leaf roller, Leaf-eating caterpillar, Cotton bollworm, Cotton bridgeworm, Tea caterpillar
- Hymenoptera, Diptera, Coleoptera: Tea looper, Pine caterpillars, Spiny moths, and other related pests
Target Crops
Bt Bio Larvicide is suitable for use on various crops, including:
- Field Crops: Cotton, Paddy, Chickpea, Soybean, Tobacco, Castor, Red gram
- Vegetables: Cabbage, Okra, Tomato, Cauliflower, Chilli, Gram
- Specialty Crops: Teak
Mode of Action
The bio insecticide works by:
- Spore Ingestion: Insect larvae ingest the Bt spores when consuming treated plant material.
- Activation in Midgut: The alkaline environment in the insect’s midgut dissolves the spores and releases protein crystals.
- Protoxin Formation: The gut enzymes activate the protein crystals, converting them into active Bt toxins, known as Cry toxins.
- Binding and Pore Formation: The toxins bind to receptors on midgut cells and create pores in the cell membrane.
- Cell Lysis: The formation of pores disrupts the midgut cells, leading to cell lysis (bursting).
- Insect Death: The damaged digestive system causes starvation and eventual death of the insect larvae.
Dosage and Application
Application Method:
- Spray the bio larvicide evenly on crops.
Dosage:
- Apply 1-2 kg per acre for effective pest control.
Precautions
- Apply the product 2-3 days prior to chemical pesticides for optimal results, especially on young larvae.
- The ideal temperature for application is above 18℃, with the best performance observed when sprayed in the evening or at temperatures above 30℃.
- Reapply every 10-15 days for continued protection.
Benefits of Using Bt Bio Larvicide
- Eco-Friendly: Safe for the environment and non-target organisms.
- Organic: Approved for use in organic farming.
- Targeted Action: Specifically targets larval pests, reducing the need for broad-spectrum chemical pesticides.
- Efficient Control: Effective when used as part of an integrated pest management (IPM) strategy.
