Will it b ok to take the flowers of my potatoes I believe thy make them form better cheers

Diluted washing up liquid, / pick them off if you can or look for an organic insecticide suitable for tomatoes

As to the potatoes farmers never remove the flowers and neither do we, has no effect on the crop Dave, just don't eat the fruits.

Ok thanks for that ;-))

I had black fly on my dahlias, diluted washing up liquid in a spray bottle really works !!

Cheers ;-))
