What term describes the process of inflicting cuts around a tree bole and applying herbicide?

• A. Frilling
• B. Girding
• C. Foliar application
• D. Drugging

Answer: (A)

Frilling is the correct term for the process of making cuts around the circumference of a tree trunk or bole and then applying herbicide into those cuts. This method is used primarily to kill unwanted trees or woody plants without the need for complete removal, especially in situations where the area needs to be preserved for other vegetation or ecological balance.

The purpose of frilling is to disrupt the tree's vascular system, making it difficult for the tree to transport nutrients and water. By applying herbicide directly into the cuts, it ensures that the chemical is delivered directly to the tree's system, increasing the likelihood of effectiveness. This method can reduce the impact of herbicides on surrounding plants and minimize the risk of soil contamination.

In contrast, girdling refers to the complete removal of a strip of bark around the tree, which is also effective but differs from frilling in its execution. Foliar application involves spraying herbicide on the leaves of plants, which targets the leaves rather than the tree trunk directly. Drugging is not a commonly recognized term in the context of herbicide application and does not accurately describe any established technique in weed management.
