Yes, I'm using it. This is my 1st season using it. I've been mixing it in my sprayer and applying it that way. I have 5 peach/nectarine trees that went in the ground 2 years ago that have fruited for the 1st time this year. The general consensus on Reddit is to not treat until you see that there's something that you need to treat for, and then treat for it the following year. I had plum curculio hit them pretty hard about a month ago, and I didn't want to wait until next year. I've applied the Surround probably 4 times now, basically after every time it rains. I haven't seen any plum curculio on them since I've been treating, but they may already be done for the season, so not sure if it's a win for the Surround or just timing. I plan to continue treating for the rest of this season and next season as well, but I don't have a lot of pre-treatment data to compare it to, so I won't really know if it's working, except for the plum curculio.
