What can I use to get rid of sawfly caterpillar on white currants and gooseberry organically.

The simplest method is just to hose them off with a strong jet of water. There is a caterpillar killer based on a bacterium called Bacillus thuringensis, but the sawflies will probably be gone by the time you get it and apply it.
You can also just elave them alone .. the bushes recover quickly without much set-back, growing new leaves. It looks more serious than it is.
