Cherry tree , blackfly please help!

[daisychook]

Morning everyone please can you advise me what to do about blackfly on my cherry tree? Can I spray with roseclear or will I poison us all later when we eat the cherry rises?!?!
Sorry not sure if this is the right place to post!
Thank you
Tracey

If you read the label: it says only for use on ornamental plants

It also implies that aphids are resistant to it


and that it's harmful to bees

To be honest, unless it's very heavily infested then you don't need to do anything.
Either spray with pressurised water (hose pipe, water pistol, plantsprayer) to physically remove them or leave for the wasps, birds and other creatures to feed their babies with.

The new leaves will probably be distorted for a few weeks but new normal ones should grow.
