Hirsutella Thompsonii talc based powder 1 kg

Our Hirsutella thompsonii Talc-Based Powder is a premium biological acaricide formulated for maximum field persistence and ease of application. Using ultra-fine talc as a stable carrier, this product delivers a high concentration of live fungal spores directly to plant surfaces, where they actively seek out and eliminate destructive spider mites—naturally, safely, and with lasting power.

Ideal for farmers, greenhouse operators, and orchard managers who demand effective, residue-free pest control that aligns with organic and sustainable growing principles.

Why Choose Talc-Based Formulation?

• Enhanced Adhesion & Coverage: Ultra-fine talc particles ensure superior adherence to leaf surfaces—even under waxy or hairy leaf conditions—providing longer-lasting protection.

• Excellent Carrier Stability: Talc is inert, moisture-resistant, and protects fungal spores from environmental degradation, ensuring shelf stability and consistent field performance.

• Dusting & Spraying Flexibility: Can be applied as a direct dust in low-wind conditions or easily mixed as a wettable suspension for full-coverage spraying.

• Cost-Effective Coverage: Provides excellent crop coverage per unit, making it an economical choice for large-area applications.

Key Benefits

• Targeted Mite Elimination: Specifically parasitizes pest mites (Tetranychus spp., Panonychus spp.) without harming beneficial insects, bees, or predator mites.

• Long Residual Activity: Talc carrier helps spores persist on foliage, offering extended control and suppressing mite populations over time.

• Zero Pre-Harvest Interval (PHI): Safe to use up to the day of harvest. Leaves no chemical residues, perfect for organic certification and export-quality produce.

• IPM & Resistance Management: A vital tool in rotating or tank-mixing programs to prevent mite resistance to chemical acaricides.

Mode of Action

Spores of Hirsutella thompsonii contact the mite cuticle, germinate, and penetrate the body. The fungus grows internally, consuming the mite and eventually emerging to produce new spores. This cycle continues, creating a sustained suppressive effect in the crop canopy.

Application Guide

As a Wettable Spray (Recommended for full coverage):

1. Dosage: 3–4 grams per liter of water.

2. Mix powder in a small volume of water to form a smooth slurry.

3. Dilute to final volume with vigorous agitation.

4. Spray thoroughly, ensuring underside leaf coverage, during evening or high-humidity periods.

5. Repeat at 7–10 day intervals under pest pressure.

As a Direct Dust:

• Use a hand duster or motorized blower to apply a fine, even layer to foliage during calm, early morning hours.

Compatibility: Compatible with organic inputs. DO NOT mix with chemical fungicides. Maintain a 7–10 day gap between fungicide and Hirsutella application.
