Copper Hydroxide Chemistry and Multi-Site Action
Copper Hydroxide (FRAC Group M01) operates as a multi-site protectant. When spray deposits contact moisture on plant leaves, bioactive copper ions (Cu2+) are released gradually to denature proteins and disrupt general respiratory enzyme function in fungal spores and bacterial cells.
Its micro-granule dry flowable (DF) formulation provides far smaller copper particle sizes, delivering greater surface coverage per gram of metallic copper compared to conventional copper oxychloride.
- Citrus: Citrus canker (Xanthomonas axonopodis) and gummosis.
- Grapevines: Downy mildew (Plasmopara viticola) and anthracnose.
- Pome fruits & stone fruits: Apple scab, fire blight, and peach leaf curl.
- Vegetables: Bacterial leaf spots in chillies and tomatoes; early and late blight in potatoes.
- Rainfast adherence: Bioactive copper deposits bind firmly to waxy cuticles, resisting wash-off from sudden rain events.
Application Guidelines and Crop Safety
As a preventative contact bactericide and fungicide, Kocide must be applied prior to pathogen penetration.
Maintaining neutral spray water pH avoids excessive copper ion surge that could induce phytotoxic leaf russeting.
- Apply preventatively during early mornings before anticipated disease flushes or rain showers.
- Do not tank-mix with strongly acidic chemicals, foliar fertilizers with high chelated acids, or fosetyl-Al.
- Wear protective gloves, rubber boots, and safety goggles during measuring and knapsack spraying.

Common questions
What is the active ingredient in Kocide fungicide?
Kocide contains Copper Hydroxide 53.8% DF (dry flowable), providing high-bioavailability metallic copper.
How does Kocide control bacterial diseases like citrus canker?
Bioactive copper ions penetrate bacterial cell membranes, denaturing essential enzymes and halting bacterial replication on contact.
Why is Kocide 2000 DF preferred over traditional copper powders?
Its micro-pore dry flowable granules dissolve dust-free, provide finer leaf coverage, and adhere with superior rainfastness.
