    Hi I planted sunflowers a couple of weeks ago and they were growing great. Over the last 2 days the leaves have started to turn brown and discolored. Does anyone know the cause of this and how to treat it ?

    Looks like pest damage, have a close look.
    Could be a leaf miner.

    Cheers Pete, just had another look imagine these are mites

    Will a general pesticide do the job ?

    Not mites, leaf miners.
    If I see them I usually just squash them inside the leaf, not difficult, often they are temporary and dont go on to become an infestation.
    If they do, a general insecticide should sort them out.
