Genetic Control

Genetic control means using plants that have been selected or genetically manipulated to be resistant or less susceptible to pests. This is frequently called host plant resistance and is considered by landscape managers as one of the most important tactics available for pest resistance. Some examples include:
Oriental Dogwood (Cornus kousa)
- Oriental dogwoods (Cornus kousa) that are resistant to diseases

- such as powdery mildew and anthracnose that commonly affect common dogwood (Cornus florida)

- Crab apple varieties (Malus sp.) that resist feeding by Japanese beetles and are resistant to scab, fire blight, rust, and mildew

- River birch (Betula nigra) that is immune to bronze birch borer, instead of paper white birch (B. papyrifera)
