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, garlic, summer and winter squash, pumpkins, melons and flowers such as Coreopsis, Cosmos, Hollyhocks and Zinnias 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. Easy to apply with our Multi-Use Pump Sprayer.

Caution: For best results and bee safety, apply before you see signs of disease and before plants begin flowering. Spray when bees are not foraging, such as in the early morning or late evening, and avoid open blooms.

16 oz. concentrate

Pricey but great for people who need something gently on the tongue or mouth
Size: 4.3 Ounce (Pack of 1)
Great alternative to traditional Toothpaste. Its a bit pricey but if you are like me you dont have to share it with anyone else because they can use regular toothpaste. The minty flavor is subtle but does not cause irritation. Easy to just just like regular toothpaste. it doesnt have any whitening in it but is a comfort for those that need a toothpaste gently on the tongue or mouth. Still does the job
