The Leaf Midge, lays eggs which develop into small
maggots on the Blackcurrants, causing the young foliage to become
distorted, twisted, and then turning black.
Eventually this causes death of the shoot and a general weakening of the
plant - not always serious.
As with all midges, the Blackcurrant midge is not
easily controlled. Affected growths can be cut off and burned.
Treatment with a systemic insecticide suitable for
food crops - such as Propvado - will also be an option. Do not use at
blossom - pollinating time.
