Pests on young fruit trees

Hello, we recently planted 40 young fruit trees (1 to 2 year old): apple, pear, quince, medlar. We are now detecting a few early problems with pests and diseases and wonder if anyone can recommend an organic control (or non chemical invasive control) for young trees. 

The main problem seems to be aphids, but I think we also have some red spider mite and powdery mildew. The soil is acidic. It has not rained for the last 6 weeks so we are experiencing some unusual dry weather, however, we have two wells and the trees have been regularly watered.

The warm daytime temperatures have contrasted with some frosty nights; some of the early leaf/buds might have been caught by the frost this way. Any advice please.

    It would be good to know, to the nearest 100 kilometres, where in the world you live, steve.
    Apophthegm -  a big word for a small thought.

    If you have any rhubarb nearby, boil some of the leaves, drain off the liquid and, once cool, put it in a spray and apply it to the infected area.  That should nuke the aphids but I don't know about the rest.  Bon chance!
  • Many thanks Nick. Yes I do have rhubarb so I'll give it a go. I've also read a cup of vegtable oil per gallon of water, mixed with some garlic tea can also work as a general pesticide. Thanks again!
