Purpureocillium lilacinum Nematicide is a biological soil-applied agent formulated with high-viability spores of Purpureocillium lilacinum to control plant-parasitic nematodes without leaving chemical residues in crops or soil.
Active Microorganism

Microorganism Strain |
Purpureocillium lilacinum (formerly Paecilomyces lilacinus) |
|
Concentration Options |
2 Billion CFU/g, 10 Billion CFU/g, or 2 Billion CFU/mL |
|
Formulation |
Wettable Powder (WP) or Liquid Suspension Concentrate (SC) |
|
Source Type |
Fermentation-derived entomopathogenic and nematophagous fungus |
Biological Mode of Action
Egg Shell Penetration: Fungal hyphae attach to nematode eggs, secretes enzymes including chitinases and proteases to break down the eggshell, and consumes the internal embryo.
Adult and Juvenile Parasitism: Active hyphae parasitize juvenile (J2) stage and adult female nematodes, stopping reproduction and lowering soil population densities.
Root Colonization: The fungus colonizes root surfaces, creating a bio-barrier that limits nematode entry into plant vascular tissues.
Target Nematodes
Root-Knot Nematodes
- Meloidogyne incognita
- Meloidogyne javanica
- Meloidogyne hapla
- Meloidogyne arenaria
Meloidogyne Species
Controls egg sacs and gall-forming females embedded in root tissues to mitigate root galls, stunted plant growth, and nutrient transport disruption.
Other Plant-Parasitic Nematodes
- Cyst Nematodes (Heterodera species, Globodera species)
- Root-Lesion Nematodes (Pratylenchus species)
- Reniform Nematodes (Rotylenchulus reniformis)
- Burrowing Nematodes (Radopholus similis)
Crops & Applications
Solanaceous Crops (Tomatoes, Peppers, Eggplants)
Apply via drip irrigation post-transplanting to protect young root systems during early setup.
Cucurbits (Cucumbers, Melons, Watermelons)
Administer through soil drenching during nursery bed preparation or directly through root fertigation lines.
Fruit Trees & Vineyards (Grapes, Citrus, Apples)
Apply around the canopy dripline during active root growth periods in spring and autumn.
Tubers & Root Crops (Potatoes, Carrots)
Incorporate into soil prior to planting or inject into irrigation lines to prevent surface blemishes and crop loss.
Berries & Strawberries
Utilize as a pre-plant soil application or run through drip lines across growing cycles.

FAQ
Q: How does Purpureocillium lilacinum compare to synthetic chemical nematicides regarding crop residue limits?
A: As a biological agent, Purpureocillium lilacinum leaves zero synthetic chemical residues. This allows for application up to the day of harvest without violating maximum residue limits.
Q: Can this product be applied together with chemical fungicides?
A: Mixing directly with chemical fungicides reduces spore viability. Maintain an interval of 7 to 10 days between synthetic fungicide applications and biological treatment.
Q: What soil conditions yield optimal activity for Purpureocillium lilacinum?
A: Spores perform best in moist soil with temperatures between 15 and 30 degrees Celsius. Dry soils or temperatures exceeding 35 degrees Celsius lower germination rates.
Q: When is the most effective time to apply for root-knot nematode control?
A: Apply at or immediately before planting, followed by a second application 2 to 4 weeks later during early root formation. Early placement protects vulnerable roots prior to nematode attack.
