I tried something this year that didnāt work nicely, so itās kind of a tip. Not that it was a good idea to start with, lol.
I saw PC bites on my Bruce plums, but I knew I had a lot of thinning to do because the branches were already burdened with baby fruit. So I waited a few days to spray the curative insecticide I use (acetimiprid in this case).
Donāt wait. Iām losing more plums than expected.
(In my defense, too, I have a bad neck/back problem and thinning is one orchard chore that really irritates it!
