Copper Fungicides

The use of copper as a protective agent for crops traces back to the late 19th century, following the accidental discovery of Bordeaux mixture by Pierre-Marie-Alexis Millardet. This blend of copper sulfate and lime was found to be highly effective against downy mildew, establishing copper as a foundational element in modern plant protection. The fungicidal action of copper relies on the release of cupric ions (Cu2+). These ions disrupt the cellular proteins of fungi and bacteria, effectively destroying the pathogen upon contact.

Beyond its role in disease control, copper is also an essential micronutrient for plants, contributing to vital biochemical reactions, chlorophyll formation, and seed production. It is a dual-action element, offering both disease protection and nutritional support, making it a key component in agricultural health.
