Active Ingredient and Mode of Action
Kocide relies on inorganic copper technology to provide durable surface protection on plant foliage.
Key chemical characteristics:
- Active ingredient: Copper hydroxide formulated as dry flowable (DF) or water-dispersible granules (WG) with high metallic copper bioavailability.
- Multi-site contact activity: Copper ions (Cu2+) are absorbed by germinating fungal and bacterial spores, disrupting essential enzymes and denaturing structural proteins.
- Bactericidal and fungicidal defense: Combats both fungal spores and destructive bacterial pathogens simultaneously.
Approved Crop Applications and Target Diseases
Copper hydroxide is widely utilized across orchards, plantation crops, and open-field vegetables.
Major registered uses:
- Pomegranate: Protects against bacterial blight (Xanthomonas axonopodis pv. punicae) when sprayed preventively during flush and fruit development.
- Citrus: Defends leaves and developing fruits against citrus canker and melanose.
- Solanaceous vegetables: Provides reliable protective cover against late blight (Phytophthora infestans) and bacterial spot in tomatoes and potatoes.
- Grapes: Shields vine canopies against downy mildew (Plasmopara viticola) during periods of high humidity.
Spraying Best Practices and Crop Safety
Because copper fungicides act strictly on plant surfaces, complete and uniform spray coverage is essential.
Handling and application rules:
- Preventive timing: Apply prior to disease establishment or at the very first visual notice of symptoms.
- Tank-mix caution: Avoid mixing with strongly acidic chemicals or organophosphate compounds that could destabilize copper formulation.
- Operator safety: Wear personal protective equipment including protective overalls, rubber gloves, and eye shields to prevent dermal irritation.

Common questions
What is the active ingredient in Kocide?
Kocide contains Copper Hydroxide, an inorganic broad-spectrum contact fungicide and bactericide.
Does Kocide have systemic action inside the plant?
No, copper hydroxide is a contact protective chemical that creates a defensive barrier on the outer surface of plant foliage.
Why is Kocide widely used in pomegranate orchards?
It provides effective bactericidal action against bacterial blight (oily spot disease) caused by Xanthomonas axonopodis.
