Scale

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.
