A micro Injection is?

A micro Injection is?

• A. A way to apply a pesticide solution directly onto the trunk of a tree.
• B. When the pesticide is mixed with water and poured on the ground around the base of the tree or shrub so that the pesticide can be absorbed by the root system.
• C. Used to deliver a small quantity of a concentrated pesticide directly into the vascular system of a tree.
• D. Applied with a sprinkler system.

Answer: (C)

Micro injection delivers a small amount of concentrated pesticide directly into the tree’s vascular system, so the chemical travels with the tree’s internal transport (xylem/phloem) to reach target tissues. This creates a systemic effect, providing protection from within the tree while minimizing surface exposure, drift, and effects on the surrounding environment. It isn’t a treatment applied to the trunk surface, a soil drench around the base, or anything delivered by a sprinkler system. Those methods involve applying the pesticide outside the vascular system or in the soil, rather than introducing it directly into the tree’s vascular pathways.
