What causes pink blisters on blackcurrant leaves?


Our Advice:

Currant blister aphids are feeding on the underside of the leaves. Spray the leaves from below with Sprayday Bayer Greenfly Killer'>Greenfly Killer from Bayer or Resolva Bug Killer from Westland. Next year, start spraying as soon as the fruits start to swell.
