#plantsurgery does anyone know what has caused the distorted leaves on my black currant? Is it related to black fly earlier in the season? New leaves look ok. Thanks!

I am a similar experience last year with my black currant bush and I turned the leaves over and black fly had returned.I dusted the bush completely with a recommended powder and is brilliant this year.

Does anyone know what is causing the distorted leaves on my black currant bushes? Is it to do with black fly earlier in the season? Newer leaves look ok and no pests to see now. Thanks for advice!
