Please can anybody help me. I have a 7year old Victoria plum tree which is fanned out along a wall, every year I start of with a good crop but around july time somthing destroys them, they seem to get bitten and then rot ( see photo ) Last year I sprayed with Bayer Provado bug killer which helped but this year it hasn't worked. I would be grateful for any suggestions.
Many thanks Ricky
