HOW TO USE GUIDE PDF

Bacillus thuringiensis (Bt) is a gram-positive, soil-dwelling bacterium used as a targeted bio-insecticide. It produces crystal toxins (Cry proteins) that destroy the gut lining of susceptible insects upon ingestion. Formulated at 2 × 10^8 cells per gram on a talc carrier, it offers species-specific pest control with minimal environmental impact.

Product Specifications

  • CFU: 2 × 10^8 cells per gram (50 million viable cells/g)
  • Active Content: Spores and δ-endotoxins (Cry proteins) of Bacillus thuringiensis Kurstaki
  • Carrier: Dextrose powder (enhances adhesion to foliage)

Usage Instructions

  1. Dosage: 500 g–1 kg per acre, mixed in 200 L water.
  2. Timing: Apply at early larval stages; avoid intense sunlight (spray dawn/dusk).
  3. Target Pests:

    • Lepidoptera: Helicoverpa armigera (cotton bollworm), Plutella xylostella (diamondback moth), Spodoptera litura (tobacco cutworm)

    • Diptera: Aedes aegypti (yellow fever mosquito), Culex quinquefasciatus (house mosquito)

    • Coleoptera: Leptinotarsa decemlineata (Colorado potato beetle)

  4. Method: Spray uniformly on foliage; ensure pest ingestion.
  5. Frequency: Reapply every 7–10 days during outbreaks or after rain.
  6. Compatibility: Do not mix with broad-spectrum chemical insecticides; compatible with neem oil.
  7. Activation: Requires alkaline gut pH (≥9.5) in target pests for toxin activation.
  8. Safety: Non-toxic to plants, mammals, birds, and beneficial insects (Apis mellifera, Coccinella septempunctata).

Suitable Crops

  • Vegetables: Cabbage, tomato, cauliflower, broccoli (vs. Plutella xylostella)
  • Field Crops: Cotton (vs. Helicoverpa armigera), maize (vs. Ostrinia nubilalis), soybean
  • Fruits: Apple (vs. Cydia pomonella), grapes (vs. Lobesia botrana)
  • Others: Forest trees (vs. Lymantria dispar), stored grains (vs. Ephestia kuehniella)

Storage Instructions

  • Temperature: 4–25°C (avoid >30°C; refrigeration optimal).
  • Packaging: PP Bags
  • Shelf Life: 24 months from manufacture.
  • Precautions: Store away from alkalis/bleaches; avoid moisture exposure.

Key Advantage

Order-Specific Toxicity:
Kills pesticide-resistant Lepidoptera (e.g., Tuta absoluta) and Diptera larvae (e.g., Anopheles stephensi) without harming parasitoids (Trichogramma spp.) or pollinators.
