What is micro injection?

What is micro injection?

• A. It is an injection method that uses the 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: (A)

Micro injection means delivering a very small amount of pesticide directly into a tree trunk under pressure, so the chemical is taken up and distributed systemically within the tree. This targeted method minimizes drift and environmental exposure while providing rapid, localized control of pests that feed or move through the tree’s tissues. The other described methods aren’t micro injection: inserting a plug into a drilled hole is a different technique that relies on the plug being present in the hole, not on pressurized trunk delivery; a harness of tubing to plastic trees isn’t a real injection method; placing the pesticide in soil is soil placement, not trunk injection.
