Persimmon tree split - is this disease or fruit-load?
So bummed right now! The persimmon tree that was doing so wonderfully earlier this spring - and DID have great fruit set, despite the nearest known male tree being about 1/4 mile from my yard - has had two branches split dreadfully, one large, one small. We've had a very rainy spring, not sure if it's fostered any disease or not, but in the past seasons the leaves did have black spots on them occasionally. Yet overall the tree's grown very well, put on a ton of growth since being planted as a tiny whip in 2006.
What is going on with the tree, and will it survive this breakage? Here is the large split (and it's along the main trunk, which is not good at all):
The spot inside the branch looks like some kind of disease:
There is a lot of fruit on this large branch, which I don't know whether contributed to the branch splitting or not. I had a branch break similarly on a nearby peach tree as well.
There's another smaller branch broken off the trunk higher up (I can add picture later if needed). Again, these branches were heavy with foliage and fruit. I don't want to lose the tree, and I don't particularly want to cut off the branch while the leaves and fruit are still very green and not showing signs of problems. But am afraid that such a split on the trunk could harm the tree if not treated before winter in some way.
Can I paint it with something in the meanwhile, to seal the torn area, then consider trimming off the branch in the cooler weather when the fruit's ripened and the leaves are off? Is this a sign of some kind of common persimmon tree disease, or an odd occurrence?
Please advise if this is something you've seen before in persimmons. I can post more pics of the tree if it'd help.
