Determining Volume and Number of Injection Sites
1. How to Determine the Diameter at Breast Height (in.)
2. Carefully read label of Product to be Injected
Measure tree diameter in inches, at breast
height by using a diameter tape, OR
measure circumference and divide by Pi
(3.1415).
Use Tree DBH”, canopy size, or cubic volume of Shrub to determine total
injection volume for treatment application.
You may also need to consider plant species, geographical location, or
environmental/ soil conditions when considering how much product to inject.
When dosing calls for injection volumes indivisible by 10mL, it’s
recommended to apply at a lower rate in order to avoid phytotox or over-
regulation.
3. Using the Graduated Cylinder provided with your Kit,
measure the calculated product volume and pour into
backpack reservoir.
It’s recommended to fill backpack reservoir with water before
mixing in product.
