Bonide Captain Jack's Copper Fungicide, 32 oz Ready-to-Use Spray for Organic Gardening, Controls Common Diseases

At the beginning of the season, I noticed some black spots on my young tomato plants. After some research, I ordered this fungicide and followed the directions. Not only did it clear up my plants, but I did not have any return of the black spots, and I had more tomatoes this year than I have ever had. The plants were healthy and productive.

I wasn't real keen on spraying but did a lot of research and this product seemed to be as 'organic' as organic can be. There was no smell. It did kill the bugs (not right away) but I did notice after a good coating the bugs were less. Good size and value for the cost. I have nothing bad to say about this product. Worked well on my grapevines and apple trees.

I had a persistent red fungus attacking the leaves on my peach tree. It was aggressive and spreading fast. I used this product as directed and also pulled off the affected leaves. While I still saw some fungus after the first application, it was definitely reduced. Here’s the twist: This year, there’s zero sign of the red fungus, and my tree is bigger and healthier than ever. Did Captain Jack’s do the trick? Maybe! I can’t say for sure if it was the spray, the winter, or a mix of both, but I do believe this fungicide played a part in getting my tree back on track. It may not work overnight, but if you're consistent and patient, this product seems to help. A solid addition to your garden toolkit, especially if you're battling stubborn leaf issues. The smell is non-toxic. The bottle spray worked well. My peach tree is now two years old, so it's still relatively small. This bottle was more than enough for my one tree and many uses.

Works great but there is better products. Easy to use

I used this product, Copper Fungicide, on my fig tree, as a prevention for fig rust. I also used it on my zucchini plants, which were showing signs of powdery mildew. It worked well in both cases. The spray came out quickly and easily. It is easy to adjust the nozzle You cannot use the container upside down, but have to lower it and awkwardly spray upwards, but it is easy enough to use. Be careful not to spray it when it is windy, as you don't want it spraying in your face. Wear gloves and wash your hands as a precaution, after using the spray.
