Hi, We have a small farm 5 acres of olive trees near Pescara, Italy.
I have three walnut trees and about 15% of the walnuts when picked are black and inedible. Sometimes I have seen a small worm type maggot in some healthy ones. Is there any spray I could use to eradicate the problem?
Regards,

There's a spray for everything. Why don't you just let nature take her 15% and leave it at that.
You could of course try speaking with a native of Pescara but I'm happy to post your question.
Onwards,
Ian
