My wisteria has what looks like some kind of worm (tiny) is crawling on the leaves, killing the leaves..I am in Zone 9 of florida.
There are certainly sprays that can control them. Since I am in Upstate NY and unfamiliar with pesticides that are legal to apply in Florida, I’d suggest that you take a sample of the worm and the damage it is causing sealed in a baggie to a local garden center and have them help you choose the appropriate solution.
