Ampelomyces quisqualis powder 25 Kg Drum

Product Name:

Ampelomyces quisqualis Powdery Mildew Biofungicide

Cfu Cells/Gram:

Minimum 2 x 10⁸ (200 Million) viable spores per gram | Hyperparasitic strain specific to powdery mildew fungi.

Base:

Available in a fine, highly dispersible formulation:

• Wettable Powder (WP): For foliar spray application with strong adhesion to leaf surfaces.

• Water Soluble Powder (WS): For fertigation, soil drench, and foliar spray.

Benefits:

• Specialized Powdery Mildew Control: A strict hyperparasite that directly invades and destroys powdery mildew fungi (Podosphaera, Erysiphe, Blumeria spp.) by colonizing their mycelium and fruiting bodies.

• Curative & Preventive Action: Can be applied at the first visible signs of disease, as it actively attacks existing mildew colonies and prevents new spore production.

• Safe for Crops & Beneficials: Non-toxic to plants, pollinators (bees), and beneficial insects. Ideal for integrated pest and disease management (IPM/IDM) and organic systems.

• No Fungicide Resistance: Offers an effective resistance management tool, especially in crops where chemical fungicide resistance in powdery mildew is a concern.

• Zero Residue: Leaves no harmful residues on fruits or leaves, ensuring compliance with strict pre-harvest intervals and maximum residue limits (MRLs).

Suggested For Crops:

Highly effective in crops susceptible to powdery mildew:

• Fruits: Grapes, Apples, Strawberries, Mango, Pome & Stone Fruits

• Vegetables: Cucurbits (Cucumber, Pumpkin, Squash), Tomato, Pepper

• Ornamentals: Roses, Begonias, Gerbera, Ornamental shrubs

• Field Crops: Peas, Sunflower

• Greenhouse & Polyhouse Crops

Spray Dosage:

• Preventive Spray: Mix 3.0 - 4.0 grams of WP powder per liter of water.

• Curative Spray (Active Infection): Mix 5.0 - 6.0 grams per liter.

• Dosage per Acre: Apply 1.2 - 1.8 kg of product per acre in 300-500 liters of water, ensuring thorough coverage of both leaf surfaces.

• Application Timing: Spray in the late afternoon or early evening under conditions of high humidity (>60% RH) for optimal spore germination and infection of the mildew fungus.

Soil Application Dosage:

• Not a soil-applied product. This is a specialized foliar biofungicide.

Note:

• Critical Need for Humidity: Requires high relative humidity (ideally >70%) for 6-10 hours after spraying to initiate infection of the powdery mildew fungus.

• Coverage is Key: Complete coverage of the underside of leaves is essential, as powdery mildew often starts there.

• Compatibility: Do not mix with chemical fungicides, especially those with systemic activity against powdery mildew. Can be tank-mixed with horticultural oils (like neem oil) or potassium bicarbonate for enhanced efficacy, following a jar test first.

• Storage: Refrigerate (2-8°C) for long-term stability. Shelf life is significantly reduced at room temperature.

• Best Results: Begin applications preventively at conditions conducive to disease (warm days, cool nights) or at the very first sign of white powdery spots. Repeat applications every 7-10 days as needed, or after heavy rain.
