Captain Jack’s Liquid Copper Fungicide Concentrate

Captain Jack’s Liquid Copper Fungicide offers organic gardeners a safe way to control fungal diseases that affect vegetables, flowers, herbs, fruit trees, and shrubs. It is effective on black spot, rust, early and late blight, powdery and downy mildew, peach leaf curl and many other common garden diseases (see below). 

Captain Jack’s is approved for organic gardening and can be applied up to the day of harvest. We rely on it for controlling powdery mildew and other diseases that attack cucumbers, squash, zucchinis, pumpkins, melons and flowers such as zinnias, coreopsis and hollyhocks in the middle and end of summer. It is also an excellent preventative spray to use in the winter dormant season to prevent and control overwintering disease spores on perennials and fruit rot and peach leaf curl on fruit trees. 

The 16-ounce bottle is an economical concentrate, convenient to dilute and spray as needed. Be sure to start applications before you notice disease, or just as soon as you can see symptoms. Completely wet and cover both sides of foliage for good disease control. We rely on Captain Jack’s fungicide and recommend this product highly.
