To further delay herbicide resistance consider taking one or more of the
<br />following steps:
<br />• Use tank mixtures with herbicides from a different group if such use is
<br />permitted; Consult your local extension service or SePRO Corporation
<br />if you are unsure as to which active ingredient is currently less prone to
<br />resistance.
<br />• Adopt an integrated weed -management program for herbicide use that
<br />includes scouting and uses historical information related to herbicide use,
<br />and that considers other management practices.
<br />• Scout after herbicide application to monitor weed populations for
<br />early signs of resistance development. Indicators of possible herbicide
<br />resistance include: (1) failure to control a weed species normally controlled
<br />by the herbicide at the dose applied, especially if control is achieved
<br />on adjacent weeds; (2) a spreading patch of non -controlled plants of
<br />a particular weed species; (3) surviving plants mixed with controlled
<br />individuals of the same species. If resistance is suspected, prevent weed
<br />seed production in the affected area by using an alternative herbicide
<br />from a different group or by a mechanical method that minimizes plant
<br />fragmentation.
<br />• If a weed pest population continues to progress after treatment with this
<br />product, switch to another management strategy or herbicide with a
<br />different mode of action, if available.
<br />• Contact your local extension specialist or SePRO Corporation for
<br />additional pesticide resistance -management and/or integrated
<br />weed -management recommendations for specific weed biotypes.
<br />Stewardship Guidelines For Use
<br />Apply this product in compliance with Best Management Practices (BMP)
<br />that include site assessment, prescription, and implementation. BMP have
<br />been developed to ensure accurate applications, minimize risk of resistance
<br />development, and monitor concentrations in water to document levels
<br />needed for optimal performance and manage potential irrigation use. SePRO
<br />Corporation will work with applicators and resource managers to implement
<br />BMP for application and monitoring to meet management objectives and
<br />ensure compatibility with potential water uses.
<br />Use Precautions
<br />• There are no restrictions for recreational purposes, including swimming
<br />and fishing.
<br />Use Restrictions
<br />• Obtain Required Permits: Consult with appropriate state or local water
<br />authorities before applying this product to public waters. State or local
<br />public agencies may require permits.
<br />• Chemigation: Do not apply this product through any type of irrigation
<br />system.
<br />• For in -water applications, the maximum single application rate is 25.0
<br />Prescription Dose Units (PDU) per acre-foot of water with a limit of three
<br />applications per year.
<br />• For aquatic foliar applications, do not exceed 10.0 PDU per acre for a single
<br />application, and do not apply more than 20.0 PDU total per acre per year.
<br />• To minimize potential exposure in compost, do not allow livestock to drink
<br />treated water.
<br />• Do not compost any plant material from treated area.
<br />• Allow 14 days or greater between applications.
<br />• Do not use water containing this product for hydroponic farming.
<br />• Do not use treated water for any form of irrigation, except as described
<br />in the Application to Water Used for Irrigation on Turf and Landscape
<br />Vegetation section.
<br />• Do not use for greenhouse or nursery irrigation.
<br />• Make applications in a minimum of 10 gallons per acre (GPA) for ground
<br />and a minimum of 15 gallons per acre (GPA) for aerial applications.

<br />EC to come into contact during an application, with carrots, soybeans,
<br />grapes, tobacco, vegetable crops, flowers, ornamental shrubs or trees, or
<br />other desirable broadleaf plants, as serious injury may occur. Do not permit

<br />product to drift onto desirable broadleaf plants as injury may occur. Further
<br />information on spray drift management is provided in the Spray Drift
<br />Management section of this label.
<br />• Do not allow tank mixes of ProcellaCOR EC to sit overnight. See additional
<br />tank mix restrictions below.
<br />• Do not use organosilicone surfactants in spray mixtures of this product.
<br />• Do not tank mix this product with malathion or methyl parathion.
<br />• Do not make an application of malathion or methyl parathion within 7
<br />days of an application of this product. See additional tank mix restrictions
<br />below.
<br />Application to Water Used for Irrigation on Turf and Landscape
<br />Vegetation
<br />To reduce the potential for injury to sensitive vegetation, follow the waiting
<br />periods (between application and irrigation) and restrictions below, and inform
<br />those who irrigate with water from the treated area. Follow local and state
<br />requirements for informing those who irrigate.
<br />When monitoring ProcellaCOR EC concentrations, analyze water samples
<br />using an appropriate analytical method for both the active ingredient and the
<br />acid form. Use of HPLC (High -Performance Liquid Chromatography), which is
<br />also referenced as FaSTESTe, is recommended.
<br />Applications to invasive freshwater aquatic vegetation in slow-moving/
<br />quiescent areas of rivers (coves, oxbows or similar sites).
<br />• Users must be aware of relevant downstream use of water for irrigation
<br />that may be affected by the treatment and must ensure all label restrictions
<br />are followed. All potential downstream water intakes with irrigation
<br />practices that may be affected by the treatment must be documented and
<br />affected irrigation users notified of the restrictions associated with such
<br />treatment.
<br />Residential and other Non-Andruhural Irrigation (such as shoreline
<br />property use including irrigation of residential landscape plants and
<br />homeowner gardens, golf course irrigation, and non-residential property
<br />irrigation around business or industrial properties. Excludes greenhouse or
<br />nursery irriaation).
<br />• Turf Irrigation: Turf may be irrigated immediately after treatment.
<br />• For irrigation of landscape vegetation or other forms of non-agricultural
<br />irrigation not excluded above, conduct one of the following:
<br />o analytically verify that water contains less than 2 ppb (SePRO
<br />recommends use of FasTEST); or
<br />o if treated areas) have the potential to dilute with untreated water, follow
<br />the precautionary waiting periods described in the tables 1 and 2 below
<br />for in -water or foliar application.

<br />Susceptible Plants
<br />Do not apply where spray drift may occur to food, forage, or other plantings
<br />that might be damaged. Spray drift may damage or render crops unfit for
<br />sale, use or consumption. Small amounts of spray drift that may not be visible
<br />may injure susceptible broadleaf plants. Before making a foliar or surface
<br />spray application, please refer to your state's sensitive crop registry
<br />(if available) to identify any commercial specialty or certified organic
<br />crops that may be located nearby. At the time of a foliar or surface spray
<br />application, the wind cannot be blowing toward adjacent cotton, carrots,
<br />soybeans, conn, grain sorghum, wheat, grapes, tobacco, vegetable
<br />crops, flowers, ornamental shrubs or trees, or other desirable broadleaf
<br />plants.
