Review: Worked well on my tomatoes - 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.
Review: Good Product - 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.

## Questions & Answers

**Q: The directions say to spray both sides of the leaves. Does that mean you can't just spray it, but have to search out every leaf to get both sides?**
A: I didn't intentionally spray the backs of the leaves. I got fruit from the plants, I think just as much as I got the year before, on plants I didn't have to spray.

**Q: Does this kill or harm insects/pollinators or does it just kill the fungus?**
A: We have not seen negative results concerning bees or other pollinators. It does not kill any bugs, good or bad, that we have seen.  You must start spraying this as soon as your plants are established or as soon as you see first signs of fungus. My husband has very pleased with the results after using every week during the growing season. Wish it could help with this unbearable heat!

**Q: Where can I see the list of plants this works on before I decide to buy it?**
A: Google the product and go to there page scroll to bottom and clip contact us and ask for list of plants.

**Q: This won't harm veggies themselves right?**
A: I FORGOT TO SAY IT DOESN'T HARM THE VEGGIES :)

### ⭐⭐⭐⭐⭐ Worked well on my tomatoes
*by M***E on October 31, 2025*

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.

### ⭐⭐⭐⭐⭐ Good Product
*by S***. on October 29, 2025*

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.

### ⭐⭐⭐⭐ Helped Over Time: My Peach Tree is Thriving!
*by R***J on July 13, 2025*

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.
