| Copper/ Copper
Sulfate |
Treated water
must not exceed 1 ppm metallic copper residual if used for
potable water. Depending on specific product used, may treat
only 1/3 to 1/2 of the aquatic site at one time and do not
retreat within 7 to14 days. |
Water use restrictions
same as if a surface water intake. |
No restrictions |
| Diquat |
Do not apply to
flowing water. Do not apply to any aquatic site not under
the total control of the user. Outflow must be little to
none or do not treat within 1,000 feet of that outlet. The
water use restrictions, depending on dosage rate used, are
1 to 3 days for drinking, 1 day for livestock watering,
5 days for irrigation or spraying of food crops, and 1 to
3 days for irrigation or spraying of ornamentals or turf.
The water may be used prior to the above time limits if
the concentration of diquat dibromide (calculated as the
cation) in the treated water is < 0.02 ppm. If the treatment
area is more than 1000 feet from the water use area or intake,
the water use restrictions may be waived. If weed density
is high, only treat 1/3 to ½ of aquatic site at one
time. Do not retreat within 14 days. |
Water use restrictions
same as if a surface water intake. |
No restrictions |
| Fluridone |
Keep ¼
mile from potable water intake unless dosage rate used is
<0.02 ppm of fluridone. Cannot exceed the maximum labeled
dosage rate for a given treatment site per season. Do not
retreat within 30 days. In aquatic sites > 10 acres in size,
there is a minimum 5 acre treatment area. Depending on the
type of aquatic site treated and the formulation used, the
water use restrictions are as follows: no irrigation of
established trees for 7 days or irrigation of row crops,
turf or ornamentals for 7 to 30 days. |
Water use restrictions
same as if a surface water intake. |
No restrictions |
| Glyphosate |
Keep ½
mile from potable water intake, unless water intake can
be shut off for at least 48 hours. The water intake can
be used again prior to 48 hours only if the concentration
of glyphosate in the treated water is <0.7 ppm. Do not retreat
within 14 days. |
Water use restrictions
same as if a surface water intake. |

site must be little to none. Do not apply to flowing water.
Aquatic site must be under the total control of the user.
Do not use in aquatic sites where water is used for potable
water. |

| 2,4-D |

sprays or domestic purposes for 7 days after treatment.
For Aquathol K & Hydrothol, do not use water for irrigation,
ag sprays, livestock watering or domestic purposes for 7
to 25 days after treatment, depending on the dosage rate
used. If the treatment area is more than 1000 feet from
the water use area or intake, the water use restrictions
may be waived. Do not retreat within 14 days. |
