The term for applying herbicide to the bark of a tree from 15 to 20 inches above the ground is known as basal bark application. This method involves spraying or applying the herbicide directly onto the lower trunk of the tree, which allows the chemical to be absorbed through the bark and enter the vascular system of the plant. This technique is particularly effective for controlling woody plants and is commonly used because it minimizes the risk of harming surrounding vegetation and targets the plant directly.

In contrast, soil application refers to methods in which herbicides are applied to the soil rather than directly to the tree or plant. Foliar application involves spraying herbicides on the leaves of plants for effective absorption, while directed application refers to targeting specific plants with herbicide, but not necessarily at a particular height on the trunk. Each of these methods has its own applications and suitability, but for the specific action of applying herbicide to the bark at the mentioned height, basal bark application is the precise terminology used.
