Holes and blotch-type leafmines produced by the oak shothole leafminer coupled with necrotic tissue caused by oak anthracnose are combining to make some oaks in southwest Ohio look pretty scuzzy. The bad news is nothing can be done now to reverse the damage. The good news is that neither of these occasional springtime afflictions has a history of causing significant harm to the overall health of their oak hosts.
In 2018, around this same time period, I wrote a BYGL Alert about the damage in my garden caused by the four-lined plant bug (Poecilocapus lineatus). I was a bit upset because of the amount of damage to a wide variety of plants. I SAID I was going to take action but of course, I never got around to it. Well, that's about to change this year!
