Blackcurrant Gall Midge
Tiny white maggots are seen feeding on the shoot tips of blackcurrant bushes and prevent the leaves from achieving their full size. The affected leaves dry up and die. Shoot tips may also die back.

In minor cases picking off the infested leaves is will not be a problem (you will see the white maggots with the naked eye) but be mindful of the fact that removing too many leaves may have an impact on the crop yield. The blackcurrant varieties 'Ben Connan' and 'Ben Sarek' appear resistant to blackcurrant gall midge.
