|We have a heavy producing pear (Comice,I think) which exhibits evidence (again, I think) of coddling moths: no apparent worm holes or other surface signs of damage, "rot" inside the fruit at the blossom end of the core - with a cavity. But I have also seen another brown cavity with a brown, leathery covering (no apparent damage on surface). The second cavity doesn't seem to be connected to the cavity at the core.|
Is the 'core rot' coddling moths? What could the other cavity be?
|The symptoms you describe are not necessarily from insects such as codling moth, but could be an infection called Black Rot. The corky flesh you describe might be a result of boron deficiency. For a positive identification of the problems, it would be best to take a sample of the fruit (plus any foliar problems) to your local Extension office.|
