Copper Oxychloride Fungicide – Trusted Protective Pesticide for Fruits, Vegetables, and Field Crops
Copper Oxychloride is an inorganic copper compound used as a protective fungicide and pesticide in agriculture. Its active ingredient, copper oxychloride, contains approximately 50% metallic copper, which acts by releasing copper ions that disrupt the enzymatic systems of fungal and bacterial pathogens. This multi-site mode of action makes it exceptionally difficult for resistance to develop, ensuring long-term efficacy in crop protection.
This fungicide belongs to the broader copper-based pesticide category and is classified as a contact fungicide, meaning it must be applied to plant surfaces before infection occurs. It does not penetrate plant tissues but instead remains on the surface to prevent spore germination and microbial development. You’ll often find copper oxychloride applied in wettable powder (WP) form, particularly as Copper Oxychloride 50% WP, due to its excellent dispersion, storage stability, and ease of application.
Its versatility has made it a core component of disease prevention programs for farmers seeking low-residue copper oxychloride products that comply with international food safety standards.
How Copper Oxychloride Works to Protect Your Crops
Copper Oxychloride fungicide functions through a multi-site, contact-based mode of action. Once applied to the plant surface, it releases copper ions (Cu²⁺) that interfere with the enzymatic activities essential for fungal and bacterial cell metabolism. These copper ions disrupt protein synthesis, respiration, and membrane integrity, effectively inhibiting spore germination and pathogen development on leaves, stems, and fruits.
Because it remains on the plant surface without systemic movement, Copper Oxychloride serves as a preventative barrier rather than a curative agent. It is most effective when used before or at the early onset of infection, particularly in humid or rainy conditions where fungal outbreaks are common.
One of the key benefits of this mode of action is its low risk of resistance development. Unlike single-site fungicides, copper oxychloride pesticide acts on multiple biochemical pathways simultaneously, making it a reliable choice in long-term disease management and integrated crop protection programs.
In addition, Copper Oxychloride is highly compatible with other protective fungicides, making it ideal for tank mix strategies designed to broaden the disease control spectrum while minimizing application intervals.
Available Formulations and Active Ingredient Profiles of Copper Oxychloride Products
Copper Oxychloride is widely available in various formulations to suit different crop protection needs and application methods. The most common and globally accepted formulation is Copper Oxychloride 50% WP (wettable powder), which contains 50% metallic copper equivalent. This type of formulation is preferred for its stable dispersibility, strong adhesion, and compatibility with standard spraying equipment.
In addition to the 50% WP variant, several customized copper oxychloride products are available for different market preferences, application volumes, and tank mix strategies. Whether you’re operating in orchard systems, vegetable rows, or broadacre crops, you can select from a range of copper-based pesticide types tailored to your usage conditions.
Common Formulations of Copper Oxychloride Fungicide:
| Formulation | Active Ingredient | Form Type | Common Application |
