Definition of horticultural oil

Categorized under "General"

Definition as written by Terry:

An oil sprayed on plants and trees to smother insect pests (and their eggs); some oils also work by disrupting the membrane functions of the pest.

The highly refined oils are often called summer oil, and can be used while the plant is growing; heavier oils are called dormant oil and are applied to deciduous plants while dormant.
