APPLICATION Directions For the Bonide Copper Fungicide Concentrate (16 fl. oz.)

Shake well before use. Most conventional liquid pesticide plant sprayers can be used to apply this to plants. Mix 0.5 to 2.0 fluid ounces of this in a gallon of water. Unless otherwise stated in specific application notes, apply 1.1 to 2.3 gallons of diluted spray per 1,000 sq. ft.

For best control, start spraying before the disease is visible or when the disease is first visible on the plant. Spray all plant parts thoroughly (top and bottom of leaves), and unless otherwise directed in the crop table, repeat every 7 to 10 days. Use the higher rate to control diseases that may go dormant and overwinter. See application notes for the specific crop application interval. If possible, time applications so that at least 12 hours of dry weather follows application. Reapply after rain, following crop-specific application interval.

Hydroponic use: Apply as soon as the disease appears, or as a preventive spray 2 weeks before disease normally appears. Apply as a foliar spray only. Do not apply directly to the water in hydroponic gardening systems. Discarded water from hydroponic growing systems may be used in greenhouses and to water indoor and outdoor container plants and garden areas. Water from these systems is prohibited from being discarded directly into a water source.

When powdery mildew presence is expected on a plant, spray the plants at the minimum application interval during the first 2 weeks after emergence. To control downy mildews, leaf and fruit spots, blights, and rust, begin treatment 2 weeks before disease normally appears or when weather forecasts predict a long period of wet weather. Alternatively, begin treatment when the disease first appears, and repeat as long as needed.

To prevent fruit rots, apply at the start of flowering and unless otherwise directed in the crop table, repeat every 7 to 10 days until harvest. Fungicidal sprays are especially warranted when weather forecasts predict a long period of wet weather.
