Grape Rot Nightmare
I planted a seedless red grape vine 10 years ago and for many years the grapes would grow nicely and then suddenly be gone, rotted in a day, black rot, I believe. For a few years I thought it was birds but now I think its black rot. SO this year I bought Bonide Citrus, Fruit and Nut Orchard Spray. I sprayed it every other week as directed, also on a peach tree with no success.
Within two days all the grapes were gone, shrivled, vanished. What can I do. I am having so much trouble with fungus. My peach tree has never had one good peach, covered in black spots and goo, t he moth larvae. I used also a strong insecticide on the peace tree, thiazicide or something like that.
BUt I thought this year the grapes would b e fine. Is it impossible to grow grapes like this in NE and I should get a disease resistant vine. Or is there a very strong fungicide to prevent black or brown rot.
