Blue Copper - Copper Oxychloride 50% WP - Crystal

Crystal Blue Copper: Product Overview

Crystal Blue Copper is a copper-based contact fungicide containing Copper Oxychloride 50% WP. Crystal Crop Protection describes its fine particles as adhering to treated leaves and gradually releasing copper ions.

FRAC classifies inorganic copper in Group M01, a multi-site contact group generally considered low resistance risk. Blue Copper remains a label-controlled pesticide: FRAC classification does not authorise an unlisted crop, disease, mixture or dose.

The Government of India table below is the dose authority used for this page. Crystal's online dose display is not sufficiently clear to support a universal per-litre direction, so no pump, per-acre or general-purpose dose is invented.

Why Choose Blue Copper?

• Verified identity: Copper Oxychloride 50% in a wettable-powder formulation.
• Contact protection: the deposit acts on treated surfaces, making timely application and coverage important.
• Multi-site classification: inorganic copper is FRAC Group M01.
• Defined Indian use table: crop, disease, formulation rate and water volume are stated below.
• Conservative claims: no unsupported cure, rainfastness, residual-duration, yield or compatibility promise is included.

How Copper Oxychloride Works

1. Surface deposit: the contact formulation remains primarily on the treated plant surface.
2. Copper release: available moisture supports gradual release of copper ions from the deposit.
3. Multi-site disruption: copper interferes with multiple proteins and enzyme systems in susceptible target organisms. It must not be presented as a fully systemic rescue treatment.

Verified Indian Uses, Dose, Water and PHI

The Government table displays a dash for PHI; that must not be presented as zero days or an exemption. Follow the current physical Blue Copper pack and applicable residue requirements. Do not convert these hectare directions into a universal per-acre, per-litre or pump dose.

Application, Safety and Resistance Stewardship

• Confirm the exact crop, disease, rate, water volume, timing and harvest direction on the current physical label before spraying.
• Because this is a contact product, use the label-specified equipment and obtain uniform coverage without runoff. Do not estimate the treated area from pack size.
• Avoid breathing WP dust. Wear all label-required PPE while measuring, mixing and spraying; wash after handling.
• Keep product, spray liquid, washings and packaging away from food, feed, children, animals, ponds, drains and waterways. Copper pesticide labels warn of aquatic hazard.
• No tank-mix, antibiotic, fertiliser, adjuvant or simultaneous-use advice is provided here.

FRAC considers M01 a low-resistance-risk multi-site group, but stewardship still matters. Avoid unnecessary repeats and use a separately applied different-group product only where its own current Indian label covers the crop, disease and application window.

Frequently Asked Questions

What does Blue Copper contain?
Copper Oxychloride 50% WP.

What is its FRAC group?
Inorganic copper is FRAC Group M01, a multi-site contact group.

Is the 500 g pack one acre's dose?
No. Registered rates are per hectare, and coffee and cardamom clump rot use different quantities. Measure the treated area and follow the pack.

What is the PHI?
No numeric PHI is stated in the Government rows. Follow the physical label and applicable residue requirements.

Can Blue Copper be mixed with another input?
No mixture advice is provided. Use it standalone unless the current label and an authorised adviser expressly support the exact combination.
