Stop common plant diseases before they ruin your harvest and landscape! This natural, contact fungicide uses elemental copper ions to protect your plants by creating a toxic barrier that prevents fungal spores from germinating. It is a crucial tool for organic gardeners dealing with wet, humid conditions.

• Best For:
  • Vegetables/Edibles: Tomatoes, squash, beans, and berries (for diseases like Early Blight, Late Blight, Downy Mildew, and Powdery Mildew).
  • Ornamentals: Roses, flowers, and shrubs (for diseases like Black Spot and Rust).
  • Preventative Use: Essential during cool, wet spring weather and humid summers.
• Key Actionable Steps:
• How to Apply: Mix the liquid concentrate with water according to the label. Use a pressurized sprayer to achieve thorough, complete coverage of all leaf surfaces, including the undersides where diseases often start.
• When to Use: Apply as a preventative spray every 7 to 10 days, starting when disease conditions (cool, wet weather) are first expected.
• Post-Rain: Reapply after heavy rain, as the copper residue is easily washed off.
• Safety Note: Do not apply copper during the hottest part of the day or when temperatures are above 85°F, as this can cause leaf burn (phytotoxicity). Apply in the early morning or evening.
• Harvest Safe: Can typically be used up to the day of harvest (always check the specific product label).
