This product is a patented, fixed copper fungicide, made by combining a soluble copper fertilizer with a fatty acid, known technically as a true soap. The copper soap fungicide controls many common diseases using a low concentration of copper. The net result is an excellent vegetable, fruit and ornamental fungicide. This product is suited for use both indoors and outdoors.
Directions for Use:
Spray all plant surfaces (top and bottom of leaves) thoroughly with this product. 22 fluid ounces will treat 7 square yards.
Begin treatment 2 weeks before disease normally appears or when disease first appears, and repeat at 7 to 10 day intervals for as long as needed. Re-apply after rain.
Powdery Mildew: Begin treatment 2 weeks before disease normally appears. Alternatively, begin treatment when disease first appears, and repeat at 7 to 10 day intervals for as long as needed. Spray every 7 days when the amount of disease is increasing rapidly. If possible, time application so that 12 hours of dry weather follow the application. On plant that are very susceptible to powdery mildew, such as home-greenhouse-grown cucumber, it is best to spray the plants twice a week during the first 2 weeks after emergence, and weekly thereafter. On outdoor plants, re-apply after rain.
Downy Mildews, Leaf and Fruit Spots, Blights, Rust: Begin treatment 2 weeks before disease normally appears or when weather forecasts predict a long period of wet weather. Alternatively, begin treatment when disease first appears, and repeat at 7 to 10 day intervals for as long as needed. Spray all plant parts thoroughly. Re-apply following heavy rain. Apply every 7 days when the amount of disease is increasing rapidly. Sprays every 5 to 7 days should be used for preventing late blight on potatoes and tomatoes. If possible, time applications so that at least 12 hours of dry weather follows the application.
Fruit Rots: Spray this product thoroughly onto flowers and fruit. Apply at the start of flowering and continue every 7 to 10 days until harvest. Fungicidal sprays are especially warranted when weather forecasts predict a long period of wet weather. Re-apply after rain.
Grapes: Do not mix this product with lime. Certain Vinifera and French Hybrid varieties may be sensitive to copper sprays resulting in marginal leaf burn. For downy mildew, black rot, leaf spot and powdery mildew on grapes, spray all plant surfaces thoroughly with this product. For best control begin treatment when new growth reaches ½ inch and repeat at 7 to 14 day intervals throughout the growing season.
For gray mold on grapes, spray all plant surfaces thoroughly with this product. For best control, begin treatment at the end of bloom, and repeat at 7 to 14 day intervals.
Peaches: For peach leaf curl, spray all plant surfaces thoroughly with this product. Apply as a dormant spray in late fall during a period of dry weather.
Ornamental Plants: Spray all plant surfaces thoroughly with this product. Begin treatment when new growth emerges and repeat every 7 to 10 days for as long as needed to control diseases. See product label for a detailed list.
Roses: For black spot, downy mildew, gray mold, leafspots, powdery mildew and rust, spray all plant surfaces thoroughly with this product. Begin treatment when new spring growth emerges and repeat every 7 to 10 days for as long as need to control disease. This product may cause some copper toxicity on some roses. Copper toxicity appears as purple spots.
This product decomposes to form soluble copper, and fatty acid, both of which can be used by microbes and plants. Fixed copper is one of the oldest fungicides and bactericides, used to control a wide range of plant diseases.
