BT BIO Larvicide – Bacillus thuringiensis Liquid Bio-Pesticide

Product Description:

              BT Bio is a naturally occurring entomopathogenic bacterium containing Bacillus thuringiensis spores and crystal proteins (Cry toxins) that specifically target and control lepidopteran (caterpillar) pests such as bollworms, fruit borers, leaf rollers, and armyworms.

When the larvae feed on BT-treated foliage, the Cry toxins get activated in their gut, causing paralysis of the digestive system. The larvae stop feeding immediately and die within 2–3 days. BT Bio is eco-friendly, non-toxic to beneficial insects, and safe for humans, animals, and the environment.

It’s a powerful biocontrol solution for organic and integrated pest management (IPM) programs.

🌱 Key Benefits

• Effectively controls caterpillars, borers, and leaf-feeding larvae
• Safe for beneficial insects like honeybees and predators
• Leaves no harmful residues – suitable for organic farming
• Reduces dependency on synthetic insecticides
• Compatible with IPM and sustainable farming practices

🐛 Target Pests

• Fruit and Shoot Borer 
• Helicoverpa (Bollworm)
• Spodoptera (Armyworm)
• Diamondback Moth (Plutella xylostella)
• Cabbage Borer, Leaf Roller, Cutworm, and Stem Borer

🌾 Recommended Crops

Cotton, Paddy, Maize, Sugarcane, Vegetables (Tomato, Brinjal, Cabbage, Cauliflower, Okra), Pulses, and Plantation Crops

🧪 CFU Count

2×10⁹ CFU/ml (Colony Forming Units per ml)

💧 Dosage & Application

• Foliar Spray: Use 5-10 ml per litre of water and spray thoroughly on both leaf surfaces.
• Per Acre: Apply 1 litre – 2 litre per acre in 200–300 litres of water.
• For Severe Infestation: Repeat application after 7–10 days.
• Compatibility: Can be tank-mixed with neem-based biopesticides, but avoid mixing with chemical insecticides.

⚡ Mode of Action

After ingestion by larvae, the Cry toxin crystals dissolve in the alkaline gut, damaging intestinal walls, causing paralysis and death within 48–72 hours. The bacterial spores further colonize the pest body, ensuring complete control.

🌿 Why Farmers Prefer BT Bio

• Fast knock-down on caterpillars without harming natural enemies
• Ideal for organic & residue-free farming
• Safe for repeated use and long-term pest suppression
• Enhances pest resistance management when alternated with neem or Beauveria
