When using a tree injection system you should?

Apply chemical with high pressure
Ensure chemical uptake by the tree at low pressure
Use high volumes of chemical
Always inject at the base of the tree

The correct answer is: Ensure chemical uptake by the tree at low pressure

Injecting at high pressure can cause damage to the tree's vascular system, leading to decreased uptake and potentially harming the tree. Using high volumes of chemical is also not recommended, as it can result in excessive chemical in the tree's tissues. Injecting at the base of the tree may not distribute the chemical evenly throughout the canopy. Therefore, the most effective and recommended method is to ensure chemical uptake by the tree at low pressure. This allows for proper distribution and minimizes potential harm to the tree.
