Item description
Crystal Cryonil Fungicide Overview
Crystal Cryonil is a systemic fungicide containing Myclobutanil 10% WP for specific fungal diseases in apple, grapes and chilli.
Myclobutanil belongs to the triazole group of fungicides. Crystal describes Cryonil as having preventive and curative properties. It interferes with production of ergosterol, a component needed for normal fungal membrane structure and function, thereby restricting fungal growth.
Use restriction: Use Cryonil only for the crop-and-disease combinations on the current Indian product label. The water volume and pre-harvest interval differ by crop, so follow the crop-specific table rather than relying on a universal dose.
Why Choose Crystal Cryonil?
- Systemic fungicide: Crystal identifies Cryonil as a systemic product for management of its label-listed diseases.
- Preventive and curative positioning: The official Crystal product information describes both preventive and curative properties.
- Three registered crop uses: The Indian registered-use table covers apple, grapes and chilli.
- Targeted disease coverage: Registered uses include apple scab, grape powdery mildew, and chilli powdery mildew, leaf spot and die-back.
- Clear crop-specific directions: Registered water volumes and waiting periods are available for each listed crop.

How Cryonil Works
Fungi require ergosterol for normal cell-membrane structure and function. Myclobutanil inhibits the fungal process that produces ergosterol. This disruption restricts continued fungal growth. Because Cryonil is a Group 3 DMI fungicide, resistance-management decisions should follow the current label and local crop-protection guidance; a product from the same FRAC group is not a different-mode-of-action rotation.
Registered Crops and Diseases
| Crop | Registered Disease(s) |
|---|---|
| Apple | Scab |
| Grapes | Powdery mildew |
| Chilli | Powdery mildew, leaf spot and die-back |
Dosage, Water Volume and Pre-Harvest Interval
The registered formulation concentration is 0.04%, equivalent to 0.4 g of product per litre of water. Keep the official tree/hectare basis as the primary direction.
| Crop | Product Rate | Water Volume | PHI |
|---|---|---|---|
| Apple | 4 g per tree | 10 L per tree | 21 days |
| Grapes | 200 g/ha (about 80 g/acre) | 500 L/ha (about 200 L/acre) | 15 days |
| Chilli | 200 g/ha (about 80 g/acre) | 500 L/ha (about 200 L/acre) | 3 days |
PHI means pre-harvest interval: the minimum time between the final application and harvest. Acre values above are rounded conversions of the registered hectare values.
Application Guidance
- Measure accurately: Use the crop-specific concentration and water volume on the current pack label.
- Coverage: Apply with suitable equipment and obtain uniform coverage of the target crop as directed on the label.
- Waiting period: Observe the 21-day apple, 15-day grape or 3-day chilli PHI, as applicable.
- Tank mixtures: This page does not recommend any tank mix. Use a mixture only when the current labels and qualified local advice explicitly permit it.
- Resistance management: Follow the current label and a crop-specific resistance-management programme. Do not treat another Group 3 DMI product as a different-mode-of-action rotation.
