Gooseberry Plants

Hi, I am new to this particular forum and am loomking for help. I have (Iassume) a disease affecting my gooseberry plants. They are young plants and are a mixture of bought ones and ones grown from cuttings. I had a poor year last year and had some leaf die back in the autumn. I cut out the affected branches and left them over winter. This year the came into bud normally and over the last couple of weeks apart from one bush they have lost the vast majority of their leaves.

Can I save these plants or do I have to burn them?
