Peach tree leaves have white lumps.

My peach tree is in a pot but has white lumps on the leaves. The leaves are also being eaten. Any idea what they are and how I can treat it?

    Those are a normal part of a peach leaf and are called extrafloral nectaries which are produced by the tree when it senses pest attacks, as an immune response, so are the result and not the cause of your leaf damage.  Ants and wasps love the nectar these glands produce so will feed on it and protect the nectaries, attacking whatever pests are actually causing the damage (the most likely is moth caterpillars.)
    A trowel in the hand is worth a thousand lost under a bush.
