Recommended Application Guidance
| Crop | Target Disease | Application Guidance |
|---|---|---|
| Rice | Sheath blight | Target application around tillering to early booting, the highest-risk window. |
| Wheat | Rusts | Let regional rust-tracking forecasts guide your first spray date. |
| Vegetables | Alternaria | Reach the full plant, including inner and lower foliage often missed by light spraying. |
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 & Regional Tracking
In rice crops, time applications around the tillering to early booting stage during peak sheath blight risk. For wheat, track regional disease forecasting reports to determine optimal timing for first rust prevention sprays.
2. Thorough Canopy Penetration
Ensure application parameters are set to thoroughly penetrate vegetable canopies, delivering complete coverage to inner and lower foliage where Alternaria lesions establish.
Safety & Environmental Care
Always wear proper personal protective equipment (gloves, goggles, mask, protective suit) during handling, mixing, and application. Very toxic to aquatic life with long-lasting effects; prevent chemical drift or runoff into nearby water bodies, streams, and ponds. Store in original sealed container in a cool, dry, well-ventilated location away from foodstuffs and animal feed.
