Scale – Plant, Leaf – How to control

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.
