To dilute with water, it is recommended to fill the spray tank to <br />one-half full with water. Start agitation. Add correct quantity of ProcellaCOR <br />EC. Continue agitation while filling spray tank to required volume and during <br />application. <br />Foliar Application to Floating and Emergent Weeds <br />Dilute PmcellaCOR EC with water to achieve proper coverage of treated <br />plants. To dilute with water, it is recommended to fill spray tank to one-half full <br />with water. Start agitation. A surfactant must be used with all post -emergent <br />foliar applications. Use only surfactants that are approved or appropriate for <br />aquatic use. For best performance, a methylated seed oil (MSO) surfactant is <br />recommended. Read and follow all use directions and precautions on aquatic <br />surfactant label. After adding PmcellaCOR EC and surfactant, continue <br />agitation while filling spray tank to required volume and during application. <br />TANK -CLEANOUT INSTRUCTIONS <br />ProcellaCOR EC should be fully cleaned from application equipment prior to <br />use for other applications. Contact a SePRO Aquatic Specialist for guidance <br />on methods for thorough cleaning of application equipment after use of the <br />product. <br />APPLICATION METHODS <br />In -Water Application to Submersed or Floating Aquatic Weeds <br />ProcellaCOR EC can be applied via trailing hose, by sub -surface injection, or <br />surface spray as an in -water application to control weeds such as hydrilla, <br />floating heart, water hyacinth, and other susceptible weed species. This <br />product has relatively short exposure requirements for in -water treatments <br />(hours to days), but treatments with high exchange and short exposure <br />periods should be carefully planned to achieve best results. Where greater <br />plant selectivity is desired - such as when controlling hydrilla or other more <br />susceptible species, choose a lower dose in the specified range. A SePRO <br />Aquatic Specialist can provide site-specific prescriptions for optimal control <br />based on target weed, management objectives, and site conditions. <br />Apply ProcellaCOR EC to the treatment area at a prescription dose unit <br />(PDU) to achieve appropriate concentrations. A PDU is a unit of measure <br />that facilitates the calculation of the amount of product required to control <br />target plants in 1 acre-foot of water or 1 acre for foliar applications. Per Table <br />5 below, 1-25 PDU are needed to treat 1 acre-foot of water, depending on <br />target species and the percent of waterbody to be treated. <br />Use Table 5 to select the dose needed to treat 1 acre-foot of water. <br />TABLE 5: Prescription Dose Units (PDU**) per acre-foot of water* <br />Percent Area <br />of Waterbody <br />Treated <br />Eurasian <br />Watermilfoil <br />Ta et Species <br />Hybrid Variable Leaf <br />Watermilfoil Watermilfoil <br />Other <br />52% <br />3-4 <br />4-5 <br />3-5 <br />3-25 <br />>2-10% <br />2-3 <br />3-5 <br />3-4 <br />3-20 <br />>10-20% <br />1-3 <br />3-4 <br />2-4 <br />3-15 <br />>20-30% <br />1-2 <br />2-3 <br />2-3 <br />2-10 <br />>30% <br />1-2 <br />2-3 <br />1-2 <br />1-5 <br />In all cases, user may apply up to the maximum of 25 PDU per acre-foot. Consult <br />your SePRO Aquatics Specialist for site-specific recommendations. <br />" 1 PDU contains 3.17 fl. oz. of product. <br />To calculate the amount of product needed in fluid ounces, use the formula <br />below: <br />Number of acres X average depth (feet) X PDU' X 3.17 = fluid ounces <br />': from Table 5 <br />Example Calculation: <br />To control hybrid watermilfoil in 2 acres of a 5 -acre lake (>30% treated) <br />with an average depth of 2 feet: <br />2 acres X 2 feet X 3 PDU X 3.17=38.04 fl. oz. <br />For in -water applications, the maximum single application is 25.0 PDU / <br />acre-foot, with a limit of three applications per year. Allow 14 days or greater <br />between applications. Product may be applied as a concentrate or diluted <br />with water prior to or during the application process. Use an appropriate <br />application method that ensures sufficiently uniform application to the treated <br />area. <br />Foliar Application to Floating and Emergent Weeds <br />Apply PmcellaCOR EC as a foliar application to control weeds such as <br />water hyacinth, water primrose, and other susceptible floating and emergent <br />species. Use an application method that maximizes spray interception by <br />target weeds while minimizing the amount of overspray that inadvertently <br />enters the water. <br />For all foliar applications, apply ProcellaCOR EC at 5.0 to 10.0 PDU per <br />acre. Use of a surfactant is required for all foliar applications of ProcellaCOR <br />EC. Use only surfactants that are approved or appropriate for aquatic use. <br />Methylated seed soil (MSO) is a recommended surfactant and is typically <br />applied at 1.0% volume/volume. Refer to the surfactant label for use <br />directions. For best results, apply to actively growing weeds. ProcellaCOR EC <br />may be applied more than once per growing season to meet management <br />objectives. Do not exceed 10.0 PDU per acre during any individual <br />application or 20.0 PDU total per acre, per year from all combined treatments. <br />Foliar Spot Treatment <br />To prepare the spray solutions, thoroughly mix PmellaCOR EC in water at <br />a ratio of 5.0 to 10.0 PDU per 100 gallons (0.12 to 0.24% product) plus an <br />adjuvant. For best results, a methylated seed oil at 1 % volume/volume is the <br />recommended spray adjuvant. When making spot application, ensure spray <br />coverage is sufficient to wet the leaves of the target vegetation but not to the <br />point of runoff. <br />Aerial Foliar Application to Floating and Emergent Weeds <br />Apply ProcellaCOR EC in a spray volume of 15 gallons per acre (GPA) or <br />more when making a post -emergence application by air. Apply with coarse <br />to coarser droplet category per S-572 ASABE standard; see NAAA, USDA <br />or nozzle manufacturer guidelines. Follow guidelines and restrictions in the <br />Spray Drift Management and Aerial Drift Reduction Advisory sections to <br />minimize potential drift to off -target vegetation. Aircraft should be patterned <br />per Operation Safe/PAASS program for calibration and uniformity to provide <br />sufficient coverage and control. <br />Boat or Ground Foliar Application to Floating and Emergent Weeds <br />When applying ProcellaCOR EC by boat or with ground equipment to <br />emergent or floating -leaved vegetation, use boom -type, backpack or <br />hydraulic handgun equipment. Apply ProcellaCOR EC in a sufficient spray <br />volume (e.g. 20 to 100 gpa) to provide accurate and uniform distribution of <br />spray particles over the treated vegetation while minimizing mnoff. Use higher <br />spray volumes for medium to high density vegetation. For boom spraying, <br />use coarse or coarser nozzle spray quality per S-572 ASABE standard; <br />see USDA literature or nozzle manufacturer guidelines. Follow nozzle <br />manufacturer's recommendations for nozzle pressure, spacing and boom <br />height to provide a uniform spray pattern. Follow appropriate spray drift <br />management information where drift potential is a concern. <br />TANK MIXES WITH OTHER AQUATIC HERBICIDES <br />DO NOT TANK MIX ANY PESTICIDE PRODUCT WITH THIS PRODUCT <br />without first referring to the following website for the specific product: <br />www.3206tankmix.com.
