    I have been spraying dormant oil and insecticide for the past 9 years on a 10 year old magnolia tree. This year the scale is totally out of control, what can I do, short of burning or cutting the tree down?

    If you use the "search" box to "search forums" at top of this page for "scale" or "scale insect" some threads should come up which may help.

    There are several posts and comments on scale
    in this forum!

    Controls differ depending on which scale you
    have. Some scale do not need to be chemically
    sprayed or applied horticultural oil used at all.
    Biological and cultural control are common
    means to use for several scale types that attach
    to ornamental trees. Fruiting trees can be a
    different story as some scale types may not go
    away but can overwinter and re-infect a tree
    year after year until they have effectively been
    stopped.

    Below are some links that you can look through.
    If you are not satisfied with the content in the
    links then contact your Virginia Cooperative
    Extension for more information.
