,Why is it important to consider how a body of water is used before applying herbicides on
or near it?
Herbicides may have water use restrictions that dictate how the water is used after application
why is it important to consider how a body of water is used before applying herbicide to it
or near it
public water supplies may restrict or prevent the use of herbicides. restrictions may apply to
water intended for livestock, human consumption, fishing and swimming
What is the relationship between water quality and a successful herbicide treatment?
Two situations apply: weed-management actions can affect water quality. Water quality can
affect the efficacy of herbicides. For example, spraying aquatic plants may kill many of these,
which in turn could cause an algal bloom, that degrades water quality and effectiveness of
chemical treatment

or near someone's home?
2)Are there any water use restrictions associated with the site and the chemical you are using?
What documents should you keep handy while at the application site?
any product literature, a copy of the herbicide label and the safety data sheet. (SDS)
petiole
The stalk of a leaf, which joins the leaf to a node of the stem.
Turion
A thick bud that grows at the base of a leaf of some aquatic plants. This bud can break off, float
away, and form a new plant.
