Ahhh, thanks for the video. I swear I watched that very same video last year, but I came away with the idea that I wanted to use copper. I think that was because I was losing all my tiny fruit that had set :/
Soooo, cooper it is to start, and Har makes it clear sulfur is fine to use in small spray bottles. Are there any issues with using small/disposable spray bottles for copper spraying?
On the Neem oil, it has been underwhelming for me. I used it religiously two seasons ago to try and fight Citrus Leaf Miner, it never got the problem under control. Final gave spinosad a shot this past season and it did wonders. I'm sure Neem is useful, just haven't seen great results firsthand in my (limited) experience.
