Captain Jack Copper Fungicide 16 oz Concentrated Plant Disease Control Solution for Organic Gardening | Plant Disease Control Solution, For Organic Gardening

Good quality product. Lots of it. Easy use and works in garden.

Great product it arrived fast. My plants are loving it. They were suffering from bacteria they seem like their doing better but I just started using it.

Has controlled the powdery mold but not eliminated it on Zucchini plants

This concentrate is very economical. Very easy to mix into a spray bottle. effectively treat the black spot and powdery mildew on my roses.

I have been using this to treat some issues I’ve been having with peach leaf curl, after trying other methods the last few years. So far it has worked really well and even helped again when there was spotting on the leaves. Since then I’ve been using it on my roses when I suspect there may be some fungal issue.

Ive diluted the concentrate as said in the manual and sprayed on my tomato plant around 4 times a week, although it is reccommended to spray it every day for 2 weeks. Despite my haphazard application, I have not had any fungi issues on my leaves and it subjectively seems like there is less blight as I have not had to clip off many leaves. At the same time this mixture also doesnt dry out or kill the leaves, an issue I had with homemade remedies. This was for sure a great addition to my garden arsenal.

The product container was half full and the directions on hos to use was torn and couldn't see how to use.

My go-to for roses, tomatoes, any kind of squash-like plant. Oh and trees. Anything that gets powdery mildew or black spot, yellowing leaves. It’s organic magic in a bottle.

Never received it. But I've used the brand and product in my home country and it works well.
