Ampelomyces quisqualis Powder Formulation (Wettable Powder) Talc Based Powder 2 × 10⁸ CFU/g

Technical Information

HOW TO USE GUIDE PDF

Ampelomyces quisqualis is a hyperparasitic fungus used as a specialized bio-fungicide against powdery mildews. It penetrates and destroys mildew mycelia by forming pycnidia inside pathogen colonies. Formulated at 2 × 10⁸ CFU/g  on a talc carrier, it offers targeted disease suppression without phytotoxicity.

Product Specifications

• CFU: 2 × 10⁸ CFU/gper gram 
• Active Content: Spores and mycelium of Ampelomyces quisqualis 
• Carrier: Talc powder (ensures stability and foliar adhesion)

Usage Instructions

• Dosage: 500 g–1 kg/acre in 200 L water; higher rates for severe infections.
• Timing: Apply at first signs of powdery mildew; reapply every 7–10 days.
• Target Pathogens:

Podosphaera xanthii (cucurbit mildew), Erysiphe necator (grape powdery mildew)/ Blumeria graminis (cereal mildew), Sphaerotheca pannosa (rose mildew)

• Method: Spray evenly on leaves (focus on undersides); full canopy coverage.
• Frequency: 3–4 applications per season; intervals shorten during humid conditions.
• Compatibility: Avoid sulfur/copper fungicides; compatible with Bacillus subtilis or potassium bicarbonate.
• Activation: Requires >60% humidity for 6+ hours; irrigate pre-application in dry climates.
• Safety: Non-toxic to plants, bees, and beneficial mites (Phytoseiulus persimilis).

• Fruits: Grapes, strawberries, apples, peaches
• Cereals: Wheat, barley (vs. Blumeria graminis)
• Ornamentals: Roses, gerbera, lilacs
• Viticulture: Wine/table grapes (high efficacy against Erysiphe necator)

Storage Instructions

• Temperature: 15–25°C avoid >25°C
• Packaging: PP Bags
• Shelf Life: 24 months 
• Precautions: Avoid repeated temperature fluctuations; discard if clumping occurs.

Key Advantage

Intra-Hyphal Parasitism:
Uniquely colonizes powdery mildew hyphae (Erysiphe, Podosphaera spp.), causing collapse of resistant strains within 48 hours while preserving mycorrhizal fungi.
