Azalea Bark Scale

Azalea Bark Scale

October 23, 2013 Pests & Diseases

Azalea bark scale is an insect pest found on azaleas and rhododendrons.  It is similar to soft scales, as it sucks carbohydrates directly from the plant and produces a lot of honey dew, but is actually seperate from soft scales, and is known as a felty scale.

While we usually treat scale insects during their early life stages (crawler stage), fall is a good time to treat with horticultural oil.  Horticultural oil has little effect on beneficial insects and has a very low residual in the landscape.
