I used this product on my plum, nectarine, lime, orange and avocado trees and found it worked extremely well. I had hole shot disease on plum and nectarine trees along with citrus minor bacteria. This product destroyed the harmful disease and bacteria. I would purchase again.

[This review was collected as part of a promotion.] Captain Jack's Fruit Tree Spray has proven to be an excellent component of my organic gardening supplies. It successfully deters pests and diseases from my fruit trees, and I appreciate that it's safe for organic practices. The concentrate is simple to mix, and the results have been remarkable—healthier trees and diminished pest problems. I’ve applied it to my fruit trees, and it has made a significant difference. I highly recommend this for anyone looking to safeguard their fruit trees in an organic way! I definitely will be using this as my go-to spray. It seems like it does the job without being as toxic as other pesticides, and strong chemical disease sprays. Even if I need to take further action on my trees that are struggling to establish themselves, I plan on using this concentrate as my first line of defense. Right now I am spraying every week or two. I imagine as the summer progresses, I will decrease usage to once a month or so depending on insect activity and rain. I like the fact it can be used up to a few days before harvest (except berries). This spray goes a long way, and is easy to use. I put it in a 1 gallon pump sprayer, and measure with a 4 oz glass measuring cup. I just shake the bottle a few times, pour it in my measuring cup, then into the sprayer. I rinse the cup as I am filling the sprayer, then close the sprayer, shake a couple times and then pump the pressure into it to use. I would recommend using all the mixture. It seemed to clog up a bit when I let 1/3 container sit for a week. Otherwise, it is simple and feels safe to use. I only avoid areas of trees where there is a bird's nest.🪺

[This review was collected as part of a promotion.] To be honest, I'm not sure exactly what this was supposed to do. It helped one of my fruit trees thrive and survive. Keep bugs from destroying it. It was a new tree, so it did not bare fruit this season. The other one did not survive, however, I cannot specify if it was a bug issue.
