Top picture is a shinseiki pear and the bottom picture is a dolgo crab. These trees have been sprayed eight times this year, starting with two dormant oil spraying in Feb and a half dozen sprayings every other week since, of bonide fruit tree spray and daconil mix. I am determined to get some fruit this year - but doesnt seem to be working. This is on my two dolgos and the asian pear. My Eliza’s choice crab had it, but all the fruits already fell off. Any ideas what this is?
