Recommended Application Guidance
| Crop | Target Disease | Application Guidance |
|---|---|---|
| Grapes | Botrytis | Two critical windows matter most: bloom and the weeks just before harvest. |
| Apple | Scab | Get ahead of the disease — this combination performs best as a protective, not curative, treatment. |
| Vegetables | Alternaria | Act on the first visible spotting rather than waiting for widespread symptoms. |
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. Preventive Timing & Critical Windows
Apply ahead of disease establishment, as the combination provides optimal performance as a protective treatment. In vineyards, prioritize critical windows such as bloom and pre-harvest timing.
2. Early Symptom Response & Coverage
In vegetable crops, initiate treatment at the very first sign of visible spotting to prevent broad establishment. Ensure thorough foliage and fruit canopy coverage.
Safety & Environmental Care
Always wear proper personal protective equipment (gloves, goggles, mask, protective suit) during handling, mixing, and application. Toxic to aquatic organisms; prevent spray drift or chemical runoff into streams, ponds, and drainage ditches. Store in original sealed containers in a cool, dry, well-ventilated area away from foodstuffs and feed.
