Possible Pear leaf curling midge on newly received seedling: I have not found a live insect yet, but… I received a SummerCrisp pear bare-root seedling from the Pacific Northwest that has leaves that sharply curl upward and have black and chewed-out margins. IIRC some leaves were starting to come out when it arrived and they already looked that way. After a month of only a few more leaves opening and looking the same curled stunted shape, I sprayed it with insecticide Bifenthrin and with Neem oil and also with fungicide Chlorothalonil because I didn’t know what was wrong. Then it started actually sending out many more shoots with nicely shaped leaves. 2-3 weeks later some new leaves started curling again.
I leaning toward Pear Leaf Curling Midge Disease and I don’t think Minneapolis normally has this disease. Should I even keep it? It already has a bad codominant leader shape started, but that can be fixed. Otherwise how often do I need to spray? Honestly I got too many plants this year. If threw it in a bonfire, then I would order a Meader Persimmon from OGW and have the tree I really wanted but was out-of-stock during pre-order season. My new Shipova from a different vendor has normal-looking leaves.
How often does a person normally have to spray Cedar-Apple Rust & insecticide on pear in the upper midwest? I refuse to grow apples due to spray schedule.
Almost looks like it needs some minor elements. I’m sure others who know a lot more than I do, will chime in. I would try a drench with a good all purpose fertlizer with minor elements.
