Fungicide
PROTHIOCONAZOLE 250 g/L + BOSCALID 150 g/L SC
A broad-spectrum suspension concentrate fungicide combining the systemic triazole fungicide prothioconazole with the carboxamide fungicide boscalid for preventive and curative control of a wide range of fungal diseases. The dual mode of action provides broad-spectrum disease control and supports fungicide resistance management.
Active: Prothioconazole + Boscalid
Formulation: SC (Suspension Concentrate)
Preventive & Curative Control
Dual Mode Resistance Management
Product Information
Mode of Action
Prothioconazole (FRAC Group 3 – DMI fungicides) inhibits sterol (ergosterol) biosynthesis by targeting the C14-demethylase (CYP51) enzyme, disrupting fungal cell membrane formation. Boscalid (FRAC Group 7 – SDHI fungicides) inhibits succinate dehydrogenase (Complex II) in fungal mitochondria, preventing cellular respiration and energy production.
Target Diseases
- Powdery mildew
- Rusts
- Alternaria leaf spot
- Sclerotinia stem rot
- Botrytis gray mold
- Leaf spots & other fungal diseases
Recommended Application Guidance
| Crop | Target Disease | Application Guidance |
|---|---|---|
| Cereals | Rusts, powdery mildew | Start treatment as soon as pustules or mildew colonies are first spotted on lower leaves; don’t wait for canopy-wide spread. |
| Oilseed crops | Sclerotinia stem rot, Alternaria | Time the spray to flowering, when petals falling onto leaves create the main infection pathway for Sclerotinia. |
| Vegetables | Alternaria, Botrytis | Get spray penetration deep into the canopy — these pathogens establish in shaded, humid inner leaves first. |
For specific L/ha dosage rates and local dilution guidelines across registered crops, please refer to the registered product label or consult local agronomic specialists.
Application Instructions
1. Early Spotting & Disease Timing
Begin applications immediately upon first detection of pustules or mildew on lower leaves. For oilseed crops, align sprays with flowering when falling petals create primary Sclerotinia infection pathways.
2. Canopy Penetration & Resistance Management
Ensure thorough spray penetration into the inner lower canopy where shaded, humid conditions favor pathogens like Alternaria and Botrytis. Utilize as part of a rotated FRAC resistance management program.
Safety & Environmental Care
Always wear proper personal protective equipment (gloves, goggles, mask, overalls) during spray preparation and handling. Toxic to aquatic organisms with long-lasting effects; prevent chemical drift or runoff into surface waters and ditches. Store in original container in a cool, dry, well-ventilated area away from foodstuffs.
