Purpureocillium lilacinum Manufacturer for Sustainable Nematode Management

Purpureocillium lilacinum is a beneficial fungus primarily used as a biological control agent in agriculture. Its main application is the control of plant-parasitic nematodes, especially root-knot nematodes (Meloidogyne spp.), by parasitizing their eggs and females.
Recent research has also demonstrated its effectiveness against insects like the citrus psyllid and certain fungal diseases. Additionally, it can promote plant growth by colonizing root tissues and enhancing nutrient uptake.

Treatment involves applying the fungus to the soil or plants to establish it in the root zone. Common application methods include soil drenching, drip irrigation, seed treatment, and nursery root dipping.
For optimal results, it should be applied during cooler hours (morning/evening) to protect spore viability. The fungus can be integrated with many water-soluble fertilizers but should not be mixed with chemical fungicides, which can kill it.

The old and still widely recognized name is Paecilomyces lilacinus. The fungus was reclassified in 2011 based on phylogenetic analysis and moved to the new genus Purpureocillium. Other historical synonyms include Penicillium lilacinum.

It works through a biological parasitism mechanism, not chemical toxicity. The fungus’ spores attach to the nematode egg surface, then secrete enzymes—specifically chitinase and protease—that break down the eggshell. The fungus then penetrates the egg, colonizes the inside, and prevents the juvenile from hatching.
It can also attack females and mobile stages. This targeted mode of action does not harm beneficial soil organisms.

Unlike a chemical knock-down, Paecilomyces lilacinus is a preventative and long-term management tool. It works by suppressing nematode egg hatching and reducing populations over time. You may see root health improvements within a single season, but maximum population reduction typically occurs with consistent applications over 2-3 seasons.
Studies show it significantly reduces egg hatching (up to 70%) and increases plant vigor compared to untreated controls.

It is widely used on high-value fruits and vegetables susceptible to root-knot nematodes. Key crops include: tomatoes, cucumbers, peppers, strawberries, bananas, citrus, potatoes, and carrots. It’s also effective in greenhouses, nurseries, and organic farming systems.
The fungus colonizes the root zone across a wide range of soil types.

Common methods include soil drenching, drip irrigation, nursery root treatment, and seed coating.

In many integrated systems, yes—especially in organic farming or where chemical residues are a concern.
For heavily infested soils, it can be used in a rotation or integration strategy to reduce chemical input by 50-70% while improving soil health.

Yes. We understand that registration is a major hurdle for importers. We provide full export documentation including: Certificate of Analysis (COA) per batch, Material Safety Data Sheet (MSDS), Technical Data Sheet (TDS), and Certificate of Origin.
We can also supply strain information and stability data to support your local registration process.

Yes, it is safe for agricultural use. It is an environmentally friendly, non-toxic alternative to chemical nematicides. It does not leave harmful residues in soil or crops and is compatible with organic farming standards.
However, as with all microbial products, we recommend standard safety precautions: avoid inhalation of dust and wash hands after handling.
