categories of toxicity:
1. Hold the wand at
the working
height and spray
a test pattern to
measure the
application band
width.
■ Category I, High Toxicity, Red label
■ Category II, Moderate Toxicity, Yellow label
■ Category III, Low Toxicity, Blue label
■ Category IV, Light Toxicity, Green label
2. Based on the band width,
identify from the table

Keep chemicals out of the reach of children,
animals, or other unauthorized people. When
not in use, store chemicals in a safe place.
Never blow through nozzles, valve, pipes or any
other component by mouth!
b. Hold the wand at your normal
working position and spray into the bottle while walking the
distance identified in step 2 above.
c. Place the bottle on a level surface and observe the liquid
level visible through the side of the bottle. Match the liquid
level to the l/acre (liter per acre) scale on the calibration
bottle.
When handling chemicals and when spraying,
make sure you are operating in accordance with
local, state, and federal environmental protec-
tion rules and guidelines. Do not spray in very
hot or windy conditions. DO NOT POLLUTE
THE ENVIRONMENT!

e. Empty the bottle contents back into the sprayer tank.
NOTE:
For improved accuracy in calibrating your application coverage,
repeat steps 4-a through 4-e and average the results.
After spray application, take a thoroughly
cleansing shower using plenty of water and
soap, then change into clean clothes. Protective
clothing and safety gear should also be cleaned
after each use. IN CASE OF EXPOSURE TO
