Steel Extra 50WP is a reliable, broad-spectrum, protective copper fungicide and bactericide (Copper Oxychloride 50% w/w).
It creates a protective barrier on plant surfaces to prevent fungal spores and bacteria from germinating. It is a versatile, cost-effective tool for managing early and late blight, rust, and leaf spots.
Active Ingredient: Copper Oxychloride 50% w/w
Formulation: Wettable Powder (WP) designed to easily mix with water for spraying.
Mode of Action: Contact/protective fungicide. It forms a physical barrier on the surface of plant leaves and stems, stopping fungal spores from germinating and penetrating the plant
Application rates:
Mixing: Typically applied as a foliar spray. Always follow the manufacturer's specific dosage on the product label (usually ranging around 40g to 50g per 20 litres of water).
Timing: Apply in the early morning or late afternoon to avoid direct, intense sunlight which can reduce effectiveness or cause phytotoxicity.
Reapplication: Reapply every 7 to 14 days, or immediately after heavy rainfall.
Key Benefits:
Multi-Site Contact Action: It disrupts the enzyme systems and cellular functions of pathogens on contact, making it highly effective at preventing diseases before they take hold.
Bactericidal Properties: In addition to fungal diseases, it effectively treats and controls bacterial infections in crops.
Long Residual Effect: It is slow-releasing and provides extended, long-lasting protection on the leaf surface.
Weather-Resistant: When applied and allowed to dry, it demonstrates strong sticking power (rainfastness), meaning it is less prone to washing off during heavy rains.
Resistance Management: Because of its multi-site mode of action, it is excellent for preventing pathogens from developing resistance.
