Try food grade DE on the eggplants and beans. Peaches too maybe. I got a hand held duster just for that. I use it on my squash too to keep the squash bugs to a low roar.
I don’t mind the JBs on the beans - they’re only harming the leaves. And as for dusting every peach on the tree!!!
Maybe the eggplants? Does it persist? Do you wear a mask? Silica dust can’t be good for the lungs.
I’m drinking about 2 tablespoons of food grade DE a day as a chelation agent and artery scrubber. There are interesting theories about the effectiveness of DE to remove plaque from clogged arteries, and since I refuse to take statins, I’m trying this.
Don’t know if it’s working on the arteries, but my fingernails have never looked so good!
