It sounds like you have a fungus called "Brown rot" which is common for
stone fruit trees. One organic solution that can help is to make sure your
trees are pruned so that they get good air circulation and all dead branches
and old fruit is completely removed. "Brown rot" will return year after
year so you really do need to start spraying fungicide to get it under
control. I've never used any organic solutions, so I can't help you there.

Hi ya'll...

I live in Mount Pleasant TX I have never had experience with fruit trees
(plum and peaches) but we have several on our property now. They have
budded, flowered, and now have green leaves. When is it the correct time
to
spray them for pests and disease? Is it too late? Last year, the plums got
some kind of mildew (powdery mildew?) and shriveled up into nothing. I
can't
remember the name of it, but there is some kind of organic fruit spray
that
is canola based from Gardens Alive....anyone ever used it, and is it good?
