The product label of the herbicide you are using
An online video tutorial produced by King County
Guidance from your local weed control program
Advice from Uncle Larry

What type of herbicide is used for hollow stem injection?
Imazapyr
Triclopyr
2, 4-D
Glyphosate

The type of site where you will be applying the herbicide is listed on the product label
The label contains instructions for hollow stem injection
All of the above

What is the minimum Personal Protective Equipment needed for injection of knotweed?

Late in the growing season, but before the first frost
After the first hard freeze, when the plant has gone dormant

How much should you dilute the herbicide for hollow stem injection?
None
25%
50%
75%

What liquid should you use to calibrate the injector?
Water
The herbicide you will be treating with
Rubbing alcohol
Lemonade

Which internodes are the most suitable sites for injection?
The top-most internode on the plant
Internodes around waist-height
The second or third internode from the ground
Knotweed doesn’t have internodes

The knotweed stem is too small for injection if:
The injector needle splits the stem wide open
The stem is smaller than your pinky finger
The internodes look too small to hold the injected dose of herbicide
All of the above

To get the best control, one must inject:
All appropriately sized stems
Every third stem of knotweed
One stem per clump of knotweed
One stem per ten square feet of knotweed

If you have a large amount of herbicide left over after you have finished your knotweed treatment, you should:
All appropriately sized stems
Dump the remainder in a nearby creek
Distribute over your newly landscaped lawn
Consult the label for appropriate disposal

When you are cleaning the injector you need to rinse everything that came into contact with herbicide:
Once
Twice
Three times
None, you’re too tired from injecting weeds to care

When you return the injector back to King County Noxious Weed Control Program, you also need to include on a sheet of paper:
Your name
The time it took you to complete treatment
The approximate square footage treated
The approximate location of the area treated
All of the above
