Active Chemistry and Multi-Site Mode of Action
Cuprofix utilizes micro-dispersed basic copper chemistry engineered to provide long-lasting surface disease protection.
Upon spraying onto plant canopies, moisture releases bioactive cupric ions (Cu2+) that disrupt respiratory enzymes, denature cell proteins, and rupture cellular membranes in germinating fungal spores.
Its multi-site surface action ensures negligible risk of chemical resistance development among pathogenic fungi.
- Micro-dispersed copper: Fine particle sizing provides superior foliar coverage and uniform deposition
- Multi-site protection: Disrupts multiple essential fungal metabolic enzymes simultaneously
- Tenacity technology: Advanced sticking agents ensure persistent adherence during monsoonal showers
Target Crop Diseases and Approved Registrations
Cuprofix is registered across grapes, potatoes, tomatoes, and plantation crops for preventing severe epidemic disease outbreaks.
Applying preventively ahead of rainy weather or humid conditions protects leaf canopies, fruit clusters, and vine shoots.
- Grapes: Unmatched control of downy mildew (Plasmopara viticola) and anthracnose
- Potato and tomato: Early blight and late blight protection with excellent foliar retention
- Plantation crops: Prevents black pod in cocoa and berry blight in coffee
Preparation, Application, and Phytotoxicity Notes
Prepare a smooth slurry in clean water before pouring into the primary spray tank to ensure complete powder suspension.
Do not mix with strongly acidic or alkaline substances, or lime-sulfur mixtures, as incompatibility can cause severe leaf scorch.
Maintain continuous tank agitation during spraying to prevent heavy wettable particles from settling.
- Mixing discipline: Prepare a lump-free slurry and agitate tank continuously during operation
- Spray timing: Apply during cool morning or evening hours with high-volume cone nozzles
- Personal protection: Wear rubber gloves, protective clothing, and a dust mask

Common questions
What is the primary active chemistry in UPL Cuprofix?
Cuprofix contains basic copper sulphate formulation providing multi-site protective contact fungicidal activity.
Why is Cuprofix preferred for grape downy mildew protection?
Its micro-dispersed copper particles provide superior surface tenacity, withstanding rain wash-off to protect clusters and leaves.
Does Cuprofix carry a risk of pathogen resistance?
No, because copper acts at multiple metabolic sites in fungal cells, pathogens cannot readily develop genetic resistance.
