Purpureocillium lilacinum Active Ingredient is a targeted fungal technical material engineered for formulators and agrochemical manufacturers producing high-potency bionematicide treatments against plant-parasitic nematodes.
Biological Characteristics
Nematophagous entomopathogenic fungus targeting egg masses and juvenile stages.
Monoxenically cultivated strain profile with verified genetic sequencing.
Unicellular, ellipsoidal to fusiform phialospores suited for high soil persistence.
Mesophilic saprophytic growth targeting root-zone rhizosphere colonization.
Mode of Action
Egg Shell Enzymatic Degradation: Secretes serine proteases and chitinases to hydrolyze the protective outer shell of nematode eggs.
Juvenile Penetration: Conidial germ tubes penetrate the cuticle of sedentary juveniles, colonizing body cavities.
Rhizosphere Colonization: Establishes a physical barrier in the root zone to inhibit larval migration toward plant root tips.
Biological Targets and Applications
Root-Knot Nematodes (Meloidogyne species): Inactivation of egg clutches and infective second-stage juveniles.
Cyst Nematodes (Heterodera and Globodera species): Disruption of cyst viability and reduction of larval emergence.
Reniform and Lesion Nematodes (Rotylenchulus and Pratylenchus species): Suppression of root feeding sites and internal tissue damage.
Crop Protection Applications
Fruity Vegetables: Solanaceous crops including tomato, pepper, and eggplant under drip irrigation regimes.
Cucurbits: Cucumber, melon, and squash planted in nematode-infested soil profiles.
Perennial and Tree Crops: Citrus, banana, and vineyard rootstocks via soil drenching.
Field Crops: Potato, root tubers, and pulse crops via seed dressing or row-applied granules.
