What is a primary characteristic of barn application?

The primary characteristic of barn application is that it involves the application of pesticides specifically to the main trunks of woody plants. This method is often used to target specific pests that may be affecting the health of trees or shrubs. Applying pesticides directly to the trunks helps ensure that the active ingredients reach the pests effectively, either by direct contact or through absorption, which can be especially useful for systemic pesticides that move through the plant's vascular system.

This approach allows for more targeted treatment, reducing the potential impact on non-target organisms and minimizing pesticide drift, which can occur with broader application methods. It is particularly effective when dealing with pests such as boring insects that may be residing within the tree's bark or cambium layer. This precise targeting stands in contrast to other methods that might focus on applying materials to a broader area or different parts of the plant.
