Bordeaux mixture

Bordeaux mixture is a fungicide made from copper sulfate and slaked lime, combined in water. It is used to protect plants, especially grapes, from fungal diseases like downy mildew and powdery mildew. When applied, it creates a copper-based protective barrier on plant surfaces, inhibiting fungal growth and spread. This mixture has been used for over a century in agriculture, effectively reducing plant disease without harming the plant tissue when used correctly. It’s important to apply it properly to avoid potential copper buildup in the soil or on the plants.
