Paecilomyces Lilacinus Powder Formulation (Wettable Powder) Talc Based Powder

Paecilomyces lilacinus is a nematophagous fungus specialized in parasitizing plant-parasitic nematodes through egg and female invasion. Formulated at 2 × 10⁸ CFU/g on a talc carrier, it provides targeted, chemical-free control of root-knot and cyst nematodes while enhancing soil health.

Product Specifications

• CFU: 2 × 10⁸ per gram (200 million viable spores/g)

• Active Content: Spores and mycelium of Paecilomyces lilacinus (e.g., strain 251)

• Carrier: Talc powder (pH 6.0–7.0 for optimal activity)

Usage Instructions

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

2. Timing: Apply at transplanting/seeding; reapply 30 days later in nematode-prone areas.

3. Primary Action: Parasitizes nematode eggs/females; secretes chitinases/proteases.

4. Target Nematodes:

   • Meloidogyne incognita (root-knot nematode)

   • Heterodera glycines (soybean cyst nematode)

   • Rotylenchulus reniformis (reniform nematode)

5. Method:

   • Drench soil uniformly in root zone (0–15 cm depth).

   • Mix with compost (1 kg/100 kg) for broadcast application.

6. Frequency: 2–3 applications per crop cycle; reapply after flooding.

7. Compatibility: Avoid nematicides; compatible with Purpureocillium lilacinum.

8. Safety: Non-toxic to plants, earthworms, and beneficial nematodes (Steinernema spp.).

Suitable Crops

• Vegetables: Tomato, Brinjal, Okra, Cucurbits

• Fruits: Banana, Grapes, Citrus

• Field Crops: Soybean, Cotton, Potato

• Staple Crops: Rice, Maize

• Plantations: Coffee, Tea

Storage Instructions

• Temperature: 4–15°C (refrigeration required; >25°C reduces viability).

• Packaging: PP Bags

• Shelf Life: 24 months.

• Precautions: Avoid moisture, direct sunlight, and fungicide contamination.

Key Advantage

Egg-Specific Parasitism:

• Destroys 90–95% of Meloidogyne eggs within 72 hours

• Reduces root galls by 70–85% in infested soils (ICAR-IINRG trials)

• Suppresses nematode reproduction via chitinase-mediated eggshell degradation

Mode of Action

1. Attachment: Spores adhere to nematode eggs/females.

2. Penetration: Hyphae invade egg casings or female cuticles.

3. Degradation: Secretes enzymes (chitinase, protease) dissolving structural components.

4. Sporulation: Fungus colonizes and sporulates, cycling infection.

🌱 Agronomic Protocol:

• Apply to moist soil (>60% WHC) at 25–30°C for maximum efficacy.

• Combine with organic amendments (neem cake) to boost spore germination.

• Avoid alkaline soils (pH >8.0) – liming reduces activity.
