Trichoderma harzianum Nematicide is a biological soil inoculant containing viable fungal spores for the suppression of plant-parasitic nematodes. Formulated for integration into drip irrigation, soil drench, and seed coating protocols, this biological control agent colonizes the root zone, disrupts nematode reproduction cycles, and protects root systems in commercial vegetable, fruit, and field crop operations.

Biological Mode of Action
Direct Parasitism and Egg Degradation: Fungal hyphae detect, coil around, and penetrate nematode eggs and second-stage juveniles. The strain secretes lytic enzymes including chitinases, proteases, and glucanases that degrade the structural integrity of nematode egg shells and cuticles.
Rhizosphere Colonization and Barrier Creation: The fungus establishes a protective physical barrier along root surfaces upon application, preventing active nematode larvae from penetrating root cells and forming feeding sites.
Secondary Metabolite Production: Bioactive secondary metabolites produced during fungal growth inhibit nematode motility, reduce egg hatching success, and paralyze active juveniles in the root zone.
Induced Systemic Resistance: Fungal establishment triggers defense pathways within host roots, elevating peroxidase and polyphenol oxidase enzyme activity to strengthen root tissue against parasitic entry.

Crops and Applications
Solanaceous Crops (Tomatoes, Peppers, Eggplants): Applied via drip irrigation during transplanting to secure root zone establishment before nematode infestation cycles begin.
Cucurbits (Cucumbers, Melons, Watermelons): Administered through fertigation systems to protect fragile taproots during early vegetative growth.
Root and Tuber Crops (Potatoes, Carrots): Integrated into soil pre-planting drenches or in-furrow applications to maintain crop appearance and root integrity.
Fruit Trees and Vineyards (Grapes, Citrus, Berries): Delivered through seasonal root zone drenches to manage persistent nematode populations in perennial soil beds.
Protected Agriculture and Greenhouses: Used in soil or coconut coir substrates to maintain root health under continuous cropping cycles.

FAQ
Q: What soil temperature range supports optimal activity for Trichoderma harzianum?
A: Spore germination and root colonization begin when soil temperatures reach 12 to 15 degrees Celsius. Peak biological performance occurs between 20 and 30 degrees Celsius.
Q: Can this product be tank-mixed with chemical fungicides?
A: Tank-mixing with synthetic copper-based or broad-spectrum chemical fungicides is not recommended. Maintain an application window of 7 to 10 days between chemical fungicide treatments and biological applications.
Q: How is spore viable count maintained throughout product shelf life?
A: Low-temperature drying processes combined with protective carriers maintain spore dormancy. Multi-layer moisture barrier packaging prevents exposure to ambient humidity, maintaining declared colony counts for 12 months under cooler storage parameters.
Q: When is the optimal application window for controlling root-knot nematodes?
A: Apply prior to planting, during seeding, or immediately after transplanting. Early application allows fungal hyphae to colonize the developing root system prior to nematode egg hatch and juvenile migration.
