You can't effectively preventively spray against blackfly (which are aphids), only deal with them after they appear (if they do.) However, you can use a grease-band around the trunk to prevent ants climbing the tree as ants 'farm' aphids and carry them around, placing them on the youngest leaves.
Thanks Bob much appreciated will get myself a greaseband also keep a very keen eye on the Blackfly if and when they appear. regards Chris
I would also try to boost its health. Cherries do not like poor drainage, poor acid soils and shade. If any of these apply you need to change the conditions. Definitely feed with a general fertiliser suchs fish, blood and bone.
You can put a ring of ant powder around the base of the tree, preventing ants climbing up. It only lasts a few weeks, and of course rain will remove it. It seems to work for my currants, combined with a soapy water spray of any aphids.
