A foundation of IPM in urban landscapes is to put the right plant in the right place. This reduces plant stress and thus the long term costs of pest management. Impervious surface cover is linked to red maple condition and scale insect infestations. This publication describes impervious surface thresholds to use when selecting sites for planting red maples in urban landscapes.
This Entomology Insect Note describes the biology and control of hemispherical scale, an insect pest of many flowering trees and shrubs, as well as greenhouse plants.
