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.

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.

• 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.

Always read and follow the current Crystal Blue Copper label and leaflet. The physical pack is the final authority for approved uses, dose, water, timing, frequency, PHI, re-entry, crop safety, PPE, first aid, environmental precautions, storage and disposal. This guide does not replace the label, Indian regulation or qualified agronomic advice.
