Sorry did not see this earlier. Dr is correct, the Tar Oil once used is no longer made, but there is a substitute which is basically Horticultural soft soap. It does work too. Main problem is that is is applied in December on a wind free day, how many of them do we get?

Hi TB found this on google
" 'WINTER TREE WASH'
RHS recommended plant oil Tree wash
• Only RHS recommended winter tree wash
• Based on plant oils
• Ideal for use on fruit trees & shrubs
• Suitable for organic gardening
• Safe around children and pets
• Supplied as 500 mil unit
Tar oil washes are no longer available. Winter Tree wash is the only product recommended by the RHS for treating pests on deciduous fruit trees and bushes in the winter to treat aphids and other over wintering pests. It contains plant oils and works on contact so needs a thorough application".
Hope this helps you it seems to be about £10 per 500 bottle.
