Active chemical composition and contact bactericidal action
Copper Oxychloride provides a durable protective chemical barrier that prevents fungal spore germination and kills bacterial cells on contact.
- Releases biologically active cupric ions (Cu2+) that bind to and denature microbial respiratory enzymes (FRAC Group M01).
- Dual fungicidal and bactericidal activity: Effectively prevents bacterial leaf blights, citrus canker, and fungal leaf spots.
- Multi-site mode of action: Extremely low probability of pathogen resistance development even with long-term seasonal use.
- Wettable powder (50% WP) formulation: Formulated for high leaf adhesion and rainfast surface coverage.
Target crops and major plant diseases
Blitox is registered under CIBRC regulations across numerous horticultural, plantation, and cereal crops.
- Rice (Paddy): Prevention and control of bacterial leaf blight and false smut.
- Potato and Tomato: Protection against early blight, late blight, and bacterial wilt/canker.
- Citrus: Management of citrus canker and die-back during vegetative flushes and pruning.
- Grapes: Control of downy mildew and anthracnose leaf spots.
- Coffee and Cardamom: Control of leaf rust and capsule rot diseases.
Spraying guidelines, dosage, and crop safety
Apply Blitox preventatively before disease symptoms appear or immediately upon detecting initial localized lesions. Ensure thorough coverage of both upper and lower leaf surfaces using calibrated hollow cone nozzles. Avoid spraying during intense midday sunshine, and do not tank-mix with highly acidic chemicals to prevent copper phytotoxicity. Applicators should wear protective goggles, masks, and rubber gloves.

Common questions
What is the technical chemical in Blitox fungicide?
Blitox contains Copper Oxychloride 50% WP, a broad-spectrum contact fungicide and bactericide.
Can Blitox control bacterial diseases in crops?
Yes, its copper ions provide true bactericidal activity, controlling bacterial leaf blight in rice and canker in citrus.
Why should Blitox not be mixed with acidic agrochemicals?
Acidic mixtures cause rapid release of free copper ions, which can scorch plant leaves and cause fruit russeting.
