Purpureocillium lilacinum Biocontrol Agent is a specialized biological nematicide formulation containing viable endoparasitic fungal spores that infect, parasitize, and destroy plant-parasitic nematodes across multiple life stages without leaving synthetic chemical residues in crop tissues or soil environments.
Key Features of Purpureocillium lilacinum Biocontrol Agent
Endoparasitic Nematode Control: Targets egg masses, juveniles, and adult females of destructive root-knot (Meloidogyne species) and cyst (Globodera species) populations.
Non-Phytotoxic Profile: Safe for root systems at all growth stages, enabling flexible application throughout the cropping cycle.
Drip Irrigation Compatibility: Micronized formulation ensures continuous suspension without clogging micro-emitters or line filters.
Resistance Management Tool: Operates via physical penetration and enzymatic destruction, preventing pest adaptation common with chemical nematicides.
Zero Harvest Pre-Interval: Leaves no synthetic chemical residues, supporting compliance with strict import residue limits.
Active Microorganism
Microorganism
Purpureocillium lilacinum (Selected naturally occurring non-GMO strain)
Form
Viable fungal spores (conidia)
Purity Standard
Free from pathogenic contaminants (Salmonella, E. coli) and non-target fungal impurities.
Mode of Action
Adhesion: Fungal spores contact nematode egg shells, juveniles, or adults in the root zone.
Appressorium Formation: Spores germinate to form appressoria that anchor firmly onto the nematode cuticle or egg envelope.
Enzymatic Degradation: The fungus secretes chitinases, proteases, and lipases, digesting the structural outer layers of the host.
Internal Parasitism: Fungal hyphae penetrate the body cavity, consuming internal contents and releasing biocontrol metabolites that paralyze the host.
Sporulation: The fungus emerges from the dead nematode host, releasing new conidia into the surrounding rhizosphere to sustain biological activity.

Root-knot nematodes (Meloidogyne incognita, Meloidogyne javanica, Meloidogyne hapla)
Cyst nematodes (Heterodera glycines, Globodera rostochiensis)

FAQ
Q: What is the recommended application timing for optimal nematode control?
A: Apply during planting, transplanting, or at early root development stages. Early application allows the fungus to colonize the rhizosphere before nematode populations build up and cause structural root damage.
Q: Can this product be applied concurrently with chemical fungicides?
A: Do not mix with broad-spectrum systemic fungicides, copper compounds, or strong chemical sterilants in the same tank. Apply biological nematicides 7 to 10 days before or after chemical fungicide treatments.
Q: Will Purpureocillium lilacinum Biocontrol Agent clog fine drip irrigation emitters?
A: No. The powder formulation is micronized to pass through a 325-mesh screen, ensuring complete suspension and smooth passage through standard drip emitters, spray nozzles, and fertigation equipment.
Q: How does soil temperature affect product performance?
A: Optimal fungal activity occurs within soil temperatures between 15 and 30 degrees Celsius. Biological activity slows significantly below 10 degrees Celsius and ceases above 38 degrees Celsius.
Q: What documentation is available for regulatory registration in local markets?
A: Complete technical dossiers including strain isolation details, acute toxicity test reports, efficacy trial data, and manufacturing flowcharts are available to support distributor registration processes.
