Which statement describes a plug containing the insecticide tapped into a dill hole and set in place with a mallet?

• A. A injection method that uses pressure to place small amounts of pesticide directly into the tree trunk.
• B. A plug containing the insecticide is tapped into a dill hole and set in place with a mallet.
• C. It consists of a harness of plastic tubing connecting to plastic trees.
• D. It is a method that uses soil placement.

Answer: (B)

You’re being tested on recognizing the in-tree delivery method where an insecticide is placed directly into the tree. The described process—drilling a small hole, tapping in a plug that contains the insecticide, and using a mallet to seat it—is the plug-in method. This approach deposits the chemical inside the tree’s tissue through a pre-formed plug, creating a localized treatment zone and helping seal the entry to minimize leakage. It’s different from injecting under pressure (which uses a device to push the pesticide into the trunk), soil placement (which applies the chemical to the soil around the plant), or tubing systems (which connect to a different delivery setup). Hence, this exact description matches the plug-in method of delivering the pesticide.
