Apple tree disease

David Faulkner asked 11 years ago

My apple tree which is a ‘Family’ fan trained type about 18years old and virtually disease free until 3 years ago when a fluffy white cotton like fungus attacked it -I believe it may be red spider mite – I spend about 3hours a week spraying it after flowering – is there anything i can do at this stage to prevent it re-occuring this year ; it has seriously affected the size of the crop.

Wooly cotton on apples trees is caused by wooly aphid, a form of greenfly that attacks the bracnhes.

If you spray in May, just after flowering, with a systemic insecticide, you will get good control, put a few drops of washing up liquid in the spray tank.
