Multi-Site Copper Chemistry and Disease Control
Tribasic Copper Sulfate (FRAC Group M01) acts as a non-specific multi-site contact fungicide and bactericide. When applied to plant surfaces, copper ions (Cu2+) are released slowly into surface moisture films, penetrating fungal spores and bacterial cells to denature essential cellular enzymes.
Because of its non-specific multi-site mode of action, pathogens have an exceptionally low likelihood of developing resistance.
- Pome & stone fruits: Apple scab, peach leaf curl, and bacterial canker.
- Grapevines: Downy mildew (Plasmopara viticola) and black rot.
- Vegetables: Early blight, bacterial spot, and damping off in tomatoes, potatoes, and chillies.
- Plantations: Black pod disease in cocoa and leaf rot in arecanut.
- Excellent rain persistence: Advanced formulation micronization provides superior rainfastness compared to traditional hand-mixed Bordeaux mixtures.
Application Guidelines and Tank Compatibility
As a preventative contact fungicide, Cuprofix must be deposited onto plant surfaces prior to fungal spore germination or bacterial infection.
Maintaining proper spray pH prevents sudden copper solubilization that could trigger phytotoxic leaf scorch.
- Apply preventatively during early mornings or overcast conditions before anticipated rainfall events.
- Avoid tank-mixing with strongly acidic products or organophosphate insecticides that could cause chemical precipitation.
- Wear personal protective gear including gloves, goggles, and a dust mask when measuring and mixing the spray slurry.

Common questions
What is the active ingredient in Cuprofix fungicide?
Cuprofix contains Tribasic Copper Sulfate formulated as a wettable or dispersible protective copper fungicide and bactericide.
Can Cuprofix control bacterial diseases in addition to fungal infections?
Yes, copper ions possess strong bactericidal properties, making Cuprofix effective against bacterial leaf spots, cankers, and blights.
Why is Cuprofix preferred over traditional raw Bordeaux mixture?
Cuprofix is a pre-neutralized, ready-to-use micro-milled formulation that eliminates tedious on-farm lime mixing while providing superior rainfastness.
