You Might Have A Mite Problem

Mites usually attack the lower leave surface first, and as their population increases they move to the top. Injured leaves can appear gray, form yellow spots, become completely yellow, turn brown, growth will distort, and the leaf will eventually drop. Some mistake this for chemical damage due to the fact the symptoms can be similar meaning the distorted growth. Mites are thought to have a chemical in their salavary secreations that work as a growth regulator. When they feed, this chemical is injected into the plant killing plant cells by the minute, changing the plant cells behavior. Mites induce plant galls that develop from the injected growth regulator. This usually will not kill an entire plant or tree, normally it will just affect the small twig like branches. Because Mites can live inside the Gall they are very difficult to control. In most cases you will have to simply live with the problem. Miticides and Horticultural Oil when temperatures permit are recommended, and several treatments are usually necessary. When detected early on, infected areas can be pruned out to help control infestation as well.
