Currant blister aphid is common on red, white and black-currants. It causes distorted growth which is very noticeable, although the plant’s vigour and ability to bear fruit is not greatly affected.
Currant blister aphid is one of a number of aphids that attack currant. It is a sap-sucking insect that infests the lower leaf surface in early summer and causes leaf distortion on currant plants.
Currants affected by blister aphid still make growth and produce a good crop, and treatment is not essential
