AMINE 4 2,4-D WEED KILLER
<br />EPA REG. NO. 34704-120
<br />AQUATIC WEED CONTROL (ponds, lakes, reservoirs, marshes, bayous, drainage ditches,
<br />canals, rivers, and streams that are quiescent or slow moving) (NOT REGISTERED FOR
<br />AQUATIC USE IN NEW YORK STATE)
<br />Ditchbank application:
<br />Postemergence:
<br />Limited to 2 applications per season. Maximum of 2.0 Ibs ae/A per application. Minimum of 30 days
<br />between applications. Spot treatment permitted.
<br />Do not use on small canals with a flow rate less than 10 cubic feet per second (CFS) where water
<br />will be used for drinking purposes. CFS may be estimated by using the formula below. The approx-
<br />imate velocity needed for the calculation can be determined by observing the length of time that it
<br />takes a floating object to travel a defined distance. Divide the distance (ft.) by the time (sec.) to esti-
<br />mate velocity (ft. per sec.). Repeat 3 times and use the average to calculate CFS.
<br />Average Width (ft.) x Average Depth (ft.) x Average Velocity (ft. per sec.) = CFS
<br />For ditchbank weeds: Do not allow boom spray to be directed onto water surface. Do not spray
<br />across stream to opposite bank.
<br />For shoreline weeds: Allow no more than 2 foot overspray onto water.
<br />Floating and Emergent Weeds: Maximum of 4.0 Ibs ae /surface acre per application. Limited to 2
<br />applications per season. Minimum of 21 days between applications. Spot treatments are permitted.
<br />Apply to emergent aquatic weeds in ponds, lakes, reservoirs, marshes, bayous, drainage ditches,
<br />non - irrigation canals, rivers, and streams that are quiescent or slow moving. Coordination and
<br />approval of local and state authorities may be required, either by letter of agreement or issuance
<br />of special permits for aquatic applications.
<br />Water Use
<br />1. Water for Irrigation or sprays:
<br />A. If treated water is intended to be used only for crops or non -crop areas that are labled for direct
<br />treatment with 2,4 -D such as pastures, turf, or cereal grains, the treated water may be used to
<br />irrigate and/or mix sprays for these sites at anytime after the 2,4 -D aquatic application.
<br />B. Due to potential phytotoxicity considerations, the following restrictions are applicable: If treated
<br />water is intended to be used to irrigate or mix sprays for plants grown in commercial nurseries
<br />and greenhouses; and other plants or crops that are not labeled for direct treatment with
<br />2,4-0, the water must not be used unless one of the following restrictions has been observed:
<br />i. A setback distance from functional water intake(s) of greater than or equal to 600 ft
<br />was used for the application, or,
<br />ii. A waiting period of 7 days from the time of application has elapsed, or,
<br />iii. An approved assay indicates that the 2,4-D concentration is 100 ppb (0.1 ppm) or Tess
<br />at the water intake. Wait at least 3 days after application before initial sampling at water
<br />intake.
<br />2. Drinking water (potable water):
<br />A. Consult with appropriate state or local water authorities before applying this product to public
<br />waters. State or local agencies may require permits. The potable water use restrictions on this
<br />label are to ensure that consumption of water by the public is allowed only when the
<br />concentration of 2,4-D in the water is less than the MCL (Maximum Contaminant Level) of 70
<br />ppb. Applicators should consider the unique characteristics of the treated waters to assure that
<br />2,4 -D concentrations in potable water do not exceed 70 ppb at the time of consumption.
<br />B. For floating and emergent weed applications, the drinking water setback distance from
<br />functioning potable water intakes is greater than or equal to 600 ft.
<br />C. If no setback distance of greater than or equal to 600 ft is used for application, applicators or
<br />the authorizing organization must provide a drinking water notification prior to a 2,4-D

<br />application to the party responsible for public water supply or to individual private water users.
<br />Notification to the party responsible for a public water supply or to individual private water users
<br />must be done in a manner to assure that the party is aware of the water use restrictions when
<br />this product is applied to potable water. The following is an example of a notification via
<br />posting, but other methods of notification which convey the above restrictions may be used and
<br />may be required in some cases under state or local law or as a condition of a permit.
<br />Example:
<br />Posting notification should be located every 250 ft including the shoreline of the treated area and
<br />up to 250 feet of shoreline past the application site to include immediate public access points.
<br />Posting must include the day and time of application. Posting may be removed if analysis of a
<br />sample collected at the intake 3 or more days following application shows that the concentration
<br />in the water is Tess than 70 ppb (100 ppb for irrigation or sprays), or after 7 days following
<br />application, whichever occurs first.
<br />Text of notification: Wait 7 days before diverting functioning surface water intakes from the
<br />treated aquatic she to use as drinking water, irrigation, or sprays, unless water at functioning
<br />drinking water intakes is tested at least 3 days after application and is demonstrated by assay to
<br />contain not more than 70 ppb 2,4 -D (100 ppb for irrigation or sprays).
<br />Application Date: Time:
<br />D. Following each application of this product, treated water must not be used for drinking water
<br />unless one of the following restrictions has been observed:
<br />i. A setback distance from functional water intake(s) of greater than or equal to 600 ft was
<br />used for the application, or,
<br />ii. A waiting period of at least 7 days from the time of application has elapsed,
<br />or,
<br />iii. An approved assay indicates that the 2,4-D concentration is 70 ppb (0.07 ppm) or less at
<br />the water intake. Sampling for drinking water analysis should occur no sooner than 3 days
<br />after 2,4 -D application. Analysis of samples must be completed by a laboratory that is
<br />certified under the Safe Drinking Water Act to perform drinking water analysis using a
<br />currently approved version of analytical Method Number 515, 555, other methods for
<br />2,4-D as may be listed in Title 40 CFR, Part 141.24, or Method Number 4015
<br />(immunoassay of 2,4 -D) from U.S. EPA Test Methods for Evaluating Solid Waste SW -846.
<br />E. Note: Existing potable water intakes that are no longer in use, such as those replaced by a
<br />connection to a municipal water system or a potable water well, are not considered to be
<br />functioning potable water intakes.
<br />F. Drinking water setback distances do not apply to terrestrial applications of 2,4 -D adjacent to
<br />water bodies with potable water intakes.
<br />3. Except as stated above, there are no restrictions on using water from treated
<br />areas for swimming, fishing, watering livestock or domestic purposes.
<br />Submersed Weeds: Maximum of 11.55 qts (10.8 Ibs ae) per acre -foot per application. Limited to
<br />2 applications per season. Apply to aquatic weeds in ponds, lakes, reservoirs, marshes, bayous,
<br />drainage ditches, nonirrigation canals, rivers, and streams that are quiescent or slow moving. Do
<br />not apply within 21 days of previous application. When treating moving bodies of water, applications
<br />must be made while traveling upstream to prevent concentration of 2,4-D downstream from the
<br />application. Coordination and approval of local and state authorities may be required, either by let-
<br />ter of agreement or issuance of special permits for such use.
