Description: Scales resemble bumpy bark or fine ash on branches
of fruit trees and shrubs. Wherever they feed, they
cause a reddening of tissue, usually several times the
diameter of the scale. On fruit this spot is very obvious.
When infested the limbs lose vigor and die, usually
in the top of the tree first. The removal of sap by
thousands of scales is what causes the damage.
Solution: Use Oil-AwayTM Insecticidal
Spray or Eco-OilTM Insecticidal
Spray as a “dormant oil” before bud break in
spring. “Crawlers” are born over a 2-6 week period,
starting about 2-3 weeks after bloom, but are controlled
by Oil-Away, Eco-Oil, PyolaTM Insecticidal
Spray or Green Lacewings.
