Brian, is there a certain type of Malathion you use? I see Bonide products in Home Depot, Lowes and Wal-mart but they are all different types. Some are over winter products, very few mention mites as a pest they control on the label. Several say "do not use on trees that show signs of stress, curled or wilted leaves" . I found one Bonide product that mentioned it worked on mites and aphids and worked on apples and juni's and stopped rust and was a fungicide on the Bonide site but I can not locate it anywhere.
