Fungicide
FLUDIOXONIL 7.5% + BOSCALID 22.5% SC
A suspension concentrate fungicide combining the contact protective activity of fludioxonil with the systemic SDHI activity of boscalid for broad-spectrum disease management and resistance management.
Active: Fludioxonil + Boscalid
Formulation: SC (Suspension Concentrate)
Contact + Systemic SDHI Action
Resistance Management
Product Information
Mode of Action
Fludioxonil interferes with osmotic signal transduction, preventing spore germination and fungal development (FRAC Group 12 – Phenylpyrroles). Boscalid inhibits succinate dehydrogenase (SDH) in fungal mitochondria, disrupting cellular respiration and energy production (FRAC Group 7 – SDHI Fungicides).
Target Diseases
- Botrytis gray mold
- Alternaria spp.
- Sclerotinia stem rot
- Rhizoctonia spp.
- Leaf spots
Recommended Application Guidance
| Crop | Target Disease | Application Guidance |
|---|---|---|
| Grapes | Botrytis | Bloom and pre-harvest remain the two windows where this disease does the most damage. |
| Vegetables | Alternaria | Even distribution across the plant matters more than spray volume alone. |
| Ornamentals | Gray mold | Apply ahead of high-humidity periods, since Botrytis thrives in stagnant, moist air. |
For specific ml/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. Critical Timing Windows & Environmental Triggers
Target grape applications during bloom and pre-harvest timing windows when Botrytis vulnerability peaks. In ornamental crops, spray preventively ahead of prolonged high-humidity periods to block gray mold establishment in stagnant air.
2. Uniform Coverage Optimization
Calibrate spraying equipment to ensure uniform droplet distribution across all foliage and target tissue surfaces, prioritizing even plant coverage over excessive liquid volume.
Safety & Environmental Care
Always wear proper personal protective equipment (gloves, goggles, mask, protective suit) during handling, mixing, and application. Toxic to aquatic life with long-lasting effects; prevent chemical drift or runoff into nearby waterways, streams, and ponds. Store in original sealed container in a cool, dry, well-ventilated location away from foodstuffs and animal feed.
