Dextrose Based Verticilium Lecanii Powder Formulation (Water Soluble)

Verticillium lecanii is a dual-action entomopathogenic fungus used as a bio-insecticide and bio-fungicide. It parasitizes insect pests via cuticle penetration and suppresses fungal pathogens through mycoparasitism. Formulated at 2 × 10⁸ CFU/g on a talc carrier, it targets soft-bodied arthropods and powdery mildews in integrated pest management (IPM) systems.

Product Specifications

• CFU: 2 × 10⁸ CFU/g

• Active Content: Fungal spores and mycelium of Verticillium lecanii

• Carrier: Dextrose powder (enhances adhesion and dispersion)

Usage Instructions

1. Dosage: 500 g–1 kg/acre in 200 L water for foliar/soil application.

2. Timing: Apply early morning/evening; avoid temperatures >30°C or <15°C.

3. Targets:

   • Insects: Aphis gossypii (cotton aphid), Bemisia tabaci (whitefly), Trialeurodes vaporariorum (greenhouse whitefly), Planococcus citri (citrus mealybug)

   • Fungi: Oidium spp. (powdery mildew), Sphaerotheca pannosa (rose powdery mildew)

4. Method: Spray foliage uniformly (underside focus for pests); drench soil for root-zone protection.

5. Frequency: Apply every 7–10 days during outbreaks; reapply after rain.

6. Compatibility: Do not mix with chemical fungicides; compatible with Bacillus thuringiensis.

7. Activation: Requires >85% humidity for 6–8 hours for spore germination.

8. Safety: Safe for plants, predators (Chrysoperla carnea), and pollinators.

Suitable Crops

• Vegetables: Cucumber, tomato, pepper, beans (controls aphids/powdery mildew)

• Fruits: Grapes, strawberries, citrus, apples (vs. whitefly/mildew)

• Ornamentals: Roses, chrysanthemums (vs. Sphaerotheca pannosa)

• Plantations: Coffee (vs. Planococcus citri), tea (vs. Oidium heveae)

• Protected Cultivation: Greenhouses (high humidity enhances efficacy)

Storage Instructions

• Temperature: 10–25°C (avoid freezing or >28°C).

• Packaging: PP Bags

• Shelf Life: 24 months from manufacture.

• Precautions: Store away from moisture sources; do not expose to direct sunlight.

Key Advantage

Dual-Pest Suppression:
Simultaneously controls resistant sap-sucking insects (Bemisia tabaci MEAM1) and fungal pathogens (Podosphaera xanthii in cucurbits) through enzymatic degradation (chitinases/proteases) and mycelial overgrowth.
