Scale
is a diseased condition of plants caused by scale insects that usually lives and feeds on plants and secretes a protective waxy covering. Scale insect sucks plant fluids for nutrition. It coats itself with a covering (hence scale) that makes it quite resistant to pesticides, which are only effective against them when they are in the juvenile crawler stage. Scale, however can be controlled with horticultural oil, which suffocates them, or through biological controls.
