Collection: Copper Fungicides

Copper fungicide is a trusted solution for managing plant diseases in both the home garden and commercial farms. Commonly used in organic gardening, these copper based fungicides are effective against powdery mildew, downy mildew, blights, bacterial spots, and other pathogens.

Made with active ingredients like copper sulfate, copper hydroxide, and copper oxychloride, copper fungicides release copper ions that disrupt fungal growth at the cellular level. They’re available as copper fungicide concentrate or conveniently ready-to-spray formulations, providing flexibility depending on your application needs.

Benefits and Best Uses

• Controls fungal and bacterial diseases on fruits, vegetables, flowers, and ornamentals
• Safe for use in organic gardening (check the product label for organic certification)
• Offers residual protection and is often safe to use up to the day of harvest
• Available in both liquid copper fungicide and concentrate forms

Copper fungicides are especially helpful in preventing issues early in the season. To properly apply copper fungicide, always mix with water when using concentrates and follow the recommended application rate listed on the product label.

Application Tips

• Use copper fungicide concentrate for customizable mixing and broader coverage
• Choose conveniently ready-to-spray products like Bonide RTS for ease of use
• Reapply after rain for continued disease control
• Rotate with other treatments to avoid copper buildup in soil

For best results, follow all product label guidelines and avoid applying during wet weather.
