Questions

I have attached a photo of a strange development on my Autumn Flowering Cherry Tree. Is this a disease. I must mention that since I planted this tree two years ago it has been plagued with disease and while it flowers they are few and far between. I sprayed it regularly thoughout the season last year and now this funny branch has appeared. Should I dig the tree up and thrown it out and/or will it infect my other trees in the garden.

I planted three raspberry, three blackcurrant and three redcurrant last year. All in neat rows. This year they are progressing well but I noticed new shoots popping up all over the place nowhere near the main canes. My question is do I dig these up and discard or leave them?
