Metarhizium anisopliae Nematicide is a broad-spectrum biological nematicide based on concentrated fungal conidia, specifically isolated to control destructive plant-parasitic nematodes in agricultural soils. This microbial solution penetrates insect and nematode cuticles, delivering biological control without chemical residues or resistance buildup. Formulated for high physical stability, it integrates directly into soil application equipment, drip irrigation systems, and commercial fertilizer blends.

Biological Mode of Action
Adhesion and Recognition: Conidia attach to the outer cuticle of juvenile nematodes and nematode eggs in the rhizosphere.
Germination and Enzymatic Digestion: Under suitable moisture conditions, conidia germinate and produce specialized appressoria that secrete extracellular enzymes, including chitinases, proteases, and esterases, to break down the nematode cuticle.
Hyphal Penetration: Infection hyphae penetrate directly through the protective outer membrane into the body cavity.
Internal Colonization: Fungal mycelia proliferate inside the host, absorbing internal nutrients, disrupting metabolic functions, and suppressing egg hatching.
Sporulation: Upon host death, new conidia emerge on the external surface of the nematode carcass, dispersing into surrounding soil matrix to provide persistent suppressive activity.
Target Nematodes
Root-Knot Nematodes
Effective against active juveniles (J2 stage) and egg masses of root-knot species, preventing root galls and vascular damage.
Meloidogyne Species
- Meloidogyne incognita (Cotton Root-Knot Nematode)
- Meloidogyne hapla (Northern Root-Knot Nematode)
- Meloidogyne javanica (Javanese Root-Knot Nematode)
- Meloidogyne arenaria (Peanut Root-Knot Nematode)
Other Plant-Parasitic Nematodes
- Cyst Nematodes (Heterodera species, Globodera species)
- Lesion Nematodes (Pratylenchus species)
- Reniform Nematodes (Rotylenchulus reniformis)
- Dagger Nematodes (Xiphinema species)
Crops and Applications
Solanaceous Crops (Tomato, Pepper, Eggplant): Apply through root drenching or drip systems during seedling transplanting to protect early root architecture.
Cucurbits (Cucumber, Melon, Squash): Inject via fertigation prior to vine growth to control soil-dwelling juveniles.
Root and Tuber Crops (Potato, Carrot, Sweet Potato): Incorporate into bed prep or soil broadcast before planting to minimize surface damage and galling.
Perennial Fruit Trees and Vineyards (Citrus, Grape, Apple): Apply during seasonal root flushes via micro-sprinklers to suppress established sub-surface populations.
Protected Horticulture (Greenhouse Vegetables and Ornamentals): Mix with growing media or apply through recirculating irrigation systems for continuous rhizosphere protection.

FAQ
Q: What is the shelf life of Metarhizium anisopliae Nematicide, and how should it be stored?
A: Stored in unopened original moisture-barrier packaging at cool temperatures (2 to 8 degrees C), the product maintains stated CFU levels for 12 months. At ambient room temperature (20 to 25 degrees C), shelf life is 6 months. Keep in a dry place protected from direct sunlight.
Q: Is Metarhizium anisopliae Nematicide compatible with chemical fungicides and fertilizers?
A: It can be tank-mixed with most organic fertilizers, biostimulants, non-bactericidal soil amendments, and insecticides. Avoid direct mixing with systemic broad-spectrum fungicides, copper compounds, or strong alkaline solutions. Allow a minimum 7-day interval between synthetic fungicide treatments and product application.
Q: How does Metarhizium anisopliae Nematicide perform through drip irrigation systems without clogging lines?
A: The Wettable Powder formulation undergoes specialized micro-grinding and air-jet milling to achieve a particle size where 98% passes through a 325-mesh screen. It exhibits rapid dispersibility and a suspension rate exceeding 85%, ensuring smooth passage through standard drip emitters, line filters, and dosing equipment.
Q: What regulatory registration support is available for international importers?
A: Full technical dossier support is provided, including Certificate of Analysis, Safety Data Sheet, product specifications, manufacturing flow charts, toxicology summaries, and five-batch analysis reports to assist with local biological pesticide registrations.
Q: What application timing yields the highest biological efficiency against root-knot nematodes?
A: Application should occur before or during planting, seeding, or transplanting when soil temperatures exceed 15 degrees C. Pre-transplant soil treatment allows conidia to establish in the root zone prior to nematode hatch cycles, protecting primary roots during early plant establishment.
