I have a well established blackcurrant schrub which has a disease on the leaves. I was told it is “rust” and have started to treat it with a copper treatment which i use every forthnight. My question is, are the fruit safe to eat? long term will it rid the schrub of the disease or will i have to keep spraying every two weeks? i notice just before the two weeks are up the “rust” is showing again. Thanks
