Fungal diseases can be a real problem for gardeners, especially when the weather is warmer and wetter than usual. Copper fungicides are often the first line of defense, especially for gardeners who prefer to avoid chemical fungicides. Using copper fungicides is confusing, but knowing exactly when to use copper fungicide is the key to success. However, fungal diseases are difficult to control and results aren’t guaranteed. Let’s explore these issues.
Description
Don’t expect copper fungicide to cure an existing fungal disease. The product works by protecting plants against the development of new infections. Ideally, apply copper fungicide before fungus is visible. Otherwise, apply the product immediately when you first notice signs of fungal disease.
Copper (Cu) is used for more than 250 years as plant protection product in agriculture. The first uses of copper fungicides were for seed treatments against seed borne diseases in cereals. At the end of 19th century farmers started to use copper fungicides in vine grape for control of downy mildew (Plasmopara viticola). In the 20th century copper based plant protection products have been widened considerably. They are used in more than 120 crops for suppressing of more than 200 diseases.
Uses/benefits of Copper Based Fungicide
Copper fungicides represent one of the oldest active ingredients developed to fight plant diseases. Some of the first fungicides developed contained copper and were used to combat diseases of vines (i.e., black rot) and fruit (i.e., apple scab).

Direction
How to Use Copper Fungicide Typically, fungicides are applied at a rate of 1 to 3 teaspoons per gallon (5 to 15 mL. per 4 L.) of water. However, it’s critical to read the label directions carefully to determine rate of application for each specific product. Reapply the product every seven to 10 days because fungicides degrade after application. Fungicides are generally not harmful to bees. However, it’s best not to spray when bees are actively foraging on plants. Never apply copper fungicide on very hot days. Never mix copper fungicides with other chemicals. Never over-apply fungicides.
