Seems I have my own personal issues with Jap. Plums - which is surprising and frustrating. I have a lot of issues with brown rot and I have been spraying MFF for that. But the issues with Shiro and Orazk are different and I have not figure them out yet. The spots on the shiro are not just on top. I think that this is related to heat because it’s as if the fruit has spoiled (simulaur to if the fruit fell to the ground and spoiled. The spots smell and taste like warm spoiled fruit or rotting fruit. The Ozark issue could be insect, heat or disease. I have sprayed some but I would like to id the issue so I can target spray for whatever is causing this. Below are two pictures of the same plum I picked today. One side is perfect, the other side has the spot. the spots appear just as the fruit starts to color and grow rapidly. I would say that the fruit in the picture was green and spot free just 3 or 4 days ago.
