Custodia Fungicide (Azoxystrobin 11% + Tebuconazole 18.3% SC)
Experience complete crop protection and enhanced yields with Custodia, an advanced dual-action fungicide designed for modern farming.
Custodia is a premium, broad-spectrum fungicide that combines two powerful active ingredients to stop fungal diseases in their tracks. Whether you are dealing with aggressive rusts, blights, or mildews, this highly stable Suspension Concentrate (SC) works both on the leaf surface and deep inside the plant system.
Beyond just disease control, Custodia triggers a signature "Greening Effect," keeping your crops healthier for longer and maximizing your final harvest quality.
Why Choose Custodia? Key Crop Benefits
- ⏱️ Fast-Acting Curative Power: Instantly stops existing fungal infections that have already penetrated the plant tissue.
- 🛡️ Dual-Action Shield: Works as a protective barrier on the outside while curing diseases from the inside.
- ⏳ Extended Protection: Slowly releases the active ingredients over time, requiring fewer spray applications.
- 🌧️ Superior Rainfastness: The microscopic particles stick firmly to the leaf, resisting wash-off from rain or irrigation.
- 🌿 The "Greening Effect": Delays crop aging, boosts photosynthesis, and promotes a larger, higher-quality yield.

How It Works: Dual Mode of Action
Custodia utilizes a highly synergistic approach to eliminate disease and prevent fungal resistance from forming:
- Energy Depletion (Azoxystrobin): Acts as an immediate protective shield. It cuts off the cellular energy (ATP) supply of invading fungi, completely stopping newly arrived spores from germinating on the leaf.
- Structural Degradation (Tebuconazole): Moves systemically upwards through the plant. It targets and destroys the cell membranes of existing fungal infections, eradicating them from within.
- Hormonal Plant Boost: Suppresses the plant's aging hormone (ethylene), which keeps your crops visibly greener and actively photosynthesizing for a much longer period.
Target Crops & Fungal Pests
| Crop | Target Pest(s) |
|---|---|
| Wheat & Barley | Yellow Rust, Leaf Rust, Stem Rust, Septoria |
| Rice (Paddy) | Sheath Blight |

| Grapes & Apples | Downy Mildew, Powdery Mildew, Apple Scab |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Wheat, Potato, Tomato & Grapes | 300 ml | 200 L | 1.5 ml | 7 Days |
| Rice & Onion | 300 ml | 320 L | ~ 1 ml | 7 to End of Season |
| Chilli | 240 ml | 200 - 300 L | 0.8 - 1.2 ml | 5 Days |
| Apples | N/A | 8-12 L / Tree | 1 ml | 10 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: For best results, apply preventatively before diseases establish, or at the absolute first sign of symptoms (such as the flag leaf emergence stage in wheat).
- Mixing: Custodia mixes well with fertilizers (like NPK 0-52-34). However, never use silicone-based adjuvants (spreader-stickers), as they will cause severe leaf burns.
- Coverage: Ensure complete and even coverage of the plant canopy. Use adequate water (200–320 liters per acre for field crops) and maintain constant tank agitation.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use. Keep sprays away from water sources and specific apple orchards.
Frequently Asked Questions
1. Is Custodia safe to use on all apple varieties?
No. Custodia is extremely toxic to "McIntosh" lineage apple trees and will cause severe damage. Never use equipment that has held Custodia to spray McIntosh apples.
2. Can I mix Custodia with other foliar fertilizers?
Yes, it has excellent physical compatibility with most water-soluble fertilizers, like NPK 0-52-34. However, it is highly recommended to perform a small jar test before mixing a full tank.
3. What exactly is the "Greening Effect"?
The azoxystrobin in the formula suppresses plant stress hormones. This delays natural aging, keeping your crops greener and actively growing for a longer time, which directly increases final yields.
4. Should I add a silicone spreader or sticker to the tank?
Absolutely not. You must strictly avoid organosilicone adjuvants. Mixing them with Custodia breaks down the plant's natural defenses too quickly and causes severe chemical burns.
5. Is Custodia safe for bees and other beneficial insects?
Yes! When applied correctly according to label guidelines, it is highly safe for vital pollinators like honeybees and beneficial predatory insects, making it a great fit for Integrated Pest Management (IPM).
