Why Choose This Product? Key Benefits
- 🛡️Contact protection: Copper acts on disease organisms where the product reaches the treated surface.
- 🍄Fungal-disease activity: The listed scope includes downy mildew, blights and other specified fungal diseases.
- 🍊Bacterial-disease coverage: Citrus canker is included in the manufacturer’s illustrated crop-disease scope.
- 🍃Fine particles on leaves: The manufacturer describes fine particles that remain on treated leaves and help restrict fungal growth.
- 💧Gradual copper release: The copper compound releases copper ions gradually; this is not a fixed-duration or rainfastness guarantee.

How It Works: Mode of Action
Blue Copper belongs to FRAC Group M01, the copper group with action at several sites in disease organisms. It is a contact treatment, not a claim of movement throughout the plant.
- The product reaches the treatment surface: Coverage matters because the fungicide acts where it is deposited.
- Copper ions are released: The copper compound provides the active copper ions.
- Normal disease growth is disrupted: Copper affects several essential processes in susceptible disease organisms, restricting their growth.
Multi-site action is useful when planning a resistance-management programme. It does not mean every disease is controlled or that unapproved tank mixtures are safe.

A crop appearing in the list does not establish that spraying, soil drenching or treating planting material is appropriate. Each use needs its own complete label programme.
Dosage & Application Guide
Do not apply from the crop list alone. A clear product quantity and matching application programme are required for every crop. No product-dose recommendation is supplied here.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| All listed crops | See note* | See note* | See note* | See note* |
Copper oxychloride 50% WP reference information lists 750–1,000 L water/ha, approximately 303.5–404.7 L/acre, for its corresponding grape, potato, cardamom, coffee, banana, tomato, tobacco, coconut, citrus, betel and chilli records. This water range is not a Blue Copper mixing instruction and must not be used without a verified paired product dose and route. It does not cover cumin.
* Product mass and dose basis, crop-specific application route, timing, repeat interval, harvest and re-entry directions must be established from the supplied Blue Copper pack. Do not interpret an unclear unit as grams per litre, kilograms per acre or a seed-treatment dose. A missing harvest interval is not a zero-day interval.
How to Apply: Best Practices
- Confirm crop and disease: Use the matching complete crop–disease programme on the supplied pack, particularly for the qualified formulation-reference entries.
- Verify product units before mixing: Measure a wettable powder by the stated mass. Do not substitute a retailer’s per-litre figure or infer a dose from the water range.
- Use only the labelled route: A leaf treatment, root-zone drench and treatment of planting material are different uses. Do not assume one route applies across the list.
- Keep coverage and precautions together: Follow the pack’s equipment, coverage, weather, crop-stage and repeat-treatment limits.
- Do not assume mixture safety: Use tank mixtures only when the applicable directions support them. Physical mixing alone does not establish crop safety or permission to use a mixture.
Frequently Asked Questions
What is Blue Copper?It is Crystal Crop Protection’s copper oxychloride 50% WP contact fungicide. WP means wettable powder.
Does it work only against fungal disease?The manufacturer describes both fungal and bacterial disease activity, including its illustrated citrus-canker use. Match the exact crop and disease before treatment.
Is Blue Copper a systemic fungicide?It is described as a contact fungicide. Do not assume it moves throughout the plant; correct labelled placement and coverage are important.
Can I use one grams-per-litre rate for all listed crops?No single verified Blue Copper concentration is provided here. Obtain the correct crop-specific product quantity, water and route from the supplied pack before mixing.
Does the crop list authorize both spraying and drenching?No. The application route must be supported for the specific crop and disease. A general crop list or another brand’s directions cannot establish it.
