Which application method targets only the lower 2 feet of a tree trunk?

The basal application method is specifically designed to target the lower part of a tree trunk, typically up to about 2 feet above the ground. This technique involves applying herbicides or other treatment solutions directly to the lower section of the trunk. It is particularly effective for controlling certain types of woody plants and preventing them from resprouting, as it allows the chemicals to be absorbed directly into the cambium layer of the tree.

This targeted approach minimizes exposure to the rest of the tree and surrounding vegetation, making it a preferred choice in managing invasive species or unwanted trees in industrial vegetation settings. The effectiveness of this method relies on the cambial layer's ability to draw the applied substances upward towards the rest of the tree's vascular system.

In contrast, other application methods are aimed at different parts of the plants or vegetation as a whole, making them unsuitable for the specific requirement of targeting just the lower 2 feet of a tree trunk.
