Do not use Arrow 2EC on vegetable crops being grown for seed production unless specific use directions are provided . Arrow 2EC is a selective postemergence herbicide for control of annual and perennial grasses . Arrow 2EC does not control sedges or broadleaf weeds . Repeated use of Arrow 2EC (or similar postemergence grass herbicide with the same mode of action) can lead to the selection of naturally occurring biotypes that are resistant to these products in some grass species . If poor performance occurs and cannot be attributed to adverse weather or application conditions, a resistant biotype may be present . This is most likely to occur in fields where other control strategies such as crop rotation, mechanical removal, and other classes of herbicides are not used from year to year . Do not allow Arrow 2EC to come in contact with desirable grass crops such as corn, rice, sorghum, small grains, or turf, as these and other grass crops will be injured or killed . Minor leaf spotting can occur on treated plants under certain environmental conditions . New foliage is not affected . Control symptoms Treated grass weeds show a reduction in vigor and growth . Early chlorosis/necrosis of younger plant tissue is followed by a progressive collapse of the remaining foliage . Symptoms will be observed in 7- to 14-days after application depending on grass species treated and environmental conditions . When an adjuvant is to be used with this product, ADAMA suggests the use of a Chemical Producers and Distributors Association certified adjuvant . APPLICATION INFORMATION Timing of Applications Apply Arrow 2EC postemergence to actively growing grasses according to rate table directions . Applications made to grass plants stressed by insufficient moisture or hot or cold temperatures or to grass plants exceeding specified growth stages can result in unsatisfactory control . Do not apply under these conditions . In arid regions where irrigation is used to supplement limited rainfall, apply Arrow 2EC as soon as possible after an irrigation (within 7 days) . In arid regions, a second application of Arrow 2EC will provide more 5 effective control of perennial grass weeds than a single application . Make second application to actively growing grass 2 to 3 weeks after emergence of new growth . Cultivation of treated grasses 7 days prior to or within 7 days after application of Arrow 2EC can reduce weed control . DO NOT APPLY Arrow 2EC if rainfall is expected within one hour since control can be reduced . ADDITION OF ADJUVANT OR CROP OIL CONCENTRATE CROP ADJUVANT DIRECTIONS Alfalfa , Cotton, Dry Shelled Beans and Pea, Always use a crop oil concentrate* at 1 .0 qt/A by Edible Podded Legume Vegetables, Peanuts ground or 1% v/v (but not less than 1 pt/A) in the (including perennial), Potato, Soybeans, finished spray volume by air . Succulent Bean & Pea , Sugarbeets, Sunflowers 1 to 2 qts/A of liquid fertilizer (10-34-0, 28%N or 32%N), or an equivalent amount (2 .5 to 4 .0 lbs/A) of spray grade ammonium sulfate (AMS) can be added to Arrow 2EC applications in addition to the specified rate of crop oil concentrate . The addition of AMS has shown improved grass control for difficult to control species including: quackgrass, Rhizome johnsongrass, red rice, wild oats, volunteer cereals, and volunteer corn . Artichoke, Asparagus, Bushberries (including Always use a crop oil concentrate at 1% v/v in the blueberries), Canola, Carrots, Clover, Cranberries, finished spray volume unless tank mix instructions Cucurbits, Flax, Fruiting Vegetables (except indicate otherwise . tomato), Garden Beets, Garlic, Head and Stem Do not add a liquid fertilizer for these crops . Brassica Vegetables, Herbs, Hops, Leaf Petioles, Leafy Brassica Greens, Leafy Greens, Mint, Mustard Seed, Onions (dry bulbs and green), Peaches, Root Vegetables, Safflower, Sesame, Shallots (dry bulbs and green), Strawberries, Sweet Potatoes (Yams and other tuberous and corm vegetables except potato) and Tomato . Non-Bearing Food Crops, Ornamental Plants, Add a non-ionic surfactant containing at least 80% Field Corn active ingredient at the rate of 1 pt per 50 gals (0 .25% v/v) . Do not use a crop oil concentrate since it can injure flowers and foliage . Conifer Trees, Fallow Land (and other non- Always use a crop oil concentrate containing at producing agricultural areas), and Non-Crop least 15% emulsifier at 1% v/v (but not less than 1 or Non-Planted Areas pt/A) in the finished spray volume . *Acceptable crop oil concentrates would be those which contain a minimum of 80% oils and 15% emulsifier . A crop oil concentrate must contain either a petroleum or vegetable oil base and must meet all the following criteria: be non- phytotoxic, contain only EPA-exempt ingredients, provide good mixing quality, and be successful in local experience . Highly refined vegetable oils have proven more satisfactory than unrefined vegetable oils . 6 Ground Application Use of sufficient spray volumes and pressure is essential to ensure complete coverage . Use a minimum of 5 gals and a maximum of 40 gals of spray solution per acre . Under the following conditions a minimum of 10 gals per acre is required: ultra narrow row cotton, narrow row soybeans, broadleaf herbicide tank mixes, perennial grasses, volunteer corn, drought or stress conditions, heavy grass pressure, or when grasses are at or near maximum height . Failure to use a minimum of 10 gals per acre under these conditions can result in poor coverage and reduced grass control requiring repeat applications . Set spray pressures to a minimum of 30 psi and a maximum of 60 psi at the nozzle . Do not use flood nozzles . Make applications to onions (dry bulbs and green), garlic, or shallots (dry bulbs and green) in a minimum of 20 gals of spray solution per acre . Air application Use a minimum of 3 gals of spray solution per acre unless otherwise directed in this label . Increase spray volumes up to 10 gals as grass or crop foliage becomes dense . For onions (dry bulbs and green), garlic, or shallots (dry bulbs and green): When applying by air do not exceed 8 fl oz/A in a single application . In California, make air applications to onions, garlic, or shallots in a minimum of 20 gals of spray solution per acre . In states other than California, make air application to onions, garlic, or shallot in a minimum of 10 gals of spray solution per acre . Note: Crop injury can occur when Arrow 2EC is applied to onions, garlic, or shallots with aerial equipment. Spot Treatment When using hand sprayers or high volume sprayers utilizing hand guns, mix 1/4% to 1/2% (0 .33 oz to 0 .65 oz per gal) Arrow 2EC and treat to wet vegetation while not allowing runoff of spray solution . For uses requiring crop oil concentrate, include crop oil concentrate at 1% (1 .3 oz per gal) by volume . For uses requiring non-ionic surfactant, include non-ionic surfactant at 1/4% (0 .33 oz per gal) by volume . Note: If Arrow 2EC is applied as a spot treatment, care must be taken not to exceed the maximum rate allowed on a “per acre” basis or crop injury can occur. CHEMIGATION ONIONS (Dry Bulbs and Green) AND GARLIC SPRINKLER IRRIGATION APPLICATION Do not apply Arrow 2EC by chemigation in the states of Idaho, Montana, Oregon, and Washington . This product can be applied to onions and garlic by sprinkler irrigation systems including center pivot, lateral move, end tow, side (wheel) roll, travelers, big gun, solid set, or hand move . Do not apply by chemigation to any other crop or to this crop using any other type of irrigation system . Apply Arrow 2EC at the high rate specified for annual grasses (16 fl oz/A) when the grass height is at the low end of the range (application to larger grasses may not provide adequate control) . Add a crop oil concentrate containing at least 15% emulsifier at 1 quart per acre . Apply Arrow 2EC in 0 .1 to 0 .2 acre-inch of water either at the end of a regular irrigation set or as a separate application not associated with a regular irrigation using the least amount of water that provides proper distribution and coverage . Application of more than label specified quantities of irrigation water per acre can result in decreased product performance by removing the chemical from the zone of effectiveness . Use a metering device to inject the Arrow 2EC into the irrigation water at a constant flow . Constant 7 agitation must be maintained in the chemical supply tank during the entire period of herbicide application . Inject the product with a positive displacement pump into the main line ahead of a right angle turn to ensure adequate mixing . Allow time for all lines to flush the herbicide through all nozzles before turning off irrigation water . To ensure the lines are flushed and free of remaining herbicide, a dye indicator can be injected into the lines to mark the end of the application period . Do not apply Arrow 2EC through an irrigation system connected to a public water system . Public water system means a system for the provision to the public of piped water for human consumption if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year . Use Precautions 1 . Apply this product only through sprinkler irrigation systems including center pivot, lateral move, end tow, side (wheel) roll, travelers, big gun, solid set, or hand move . Do not apply this product through any other type of irrigation system . 2 . Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non- uniform distribution of treated water . 3 . If you have any questions about calibration, contact State Extension Service specialists, equipment manufacturers, or other experts . 4 . Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a public water system unless the label-prescribed safety devices for public water supplies are in place . 5 . A person knowledgeable of the chemigation system and responsible for its operation or under supervision of the responsible person shall shut the system down and make necessary adjustments as needed . 6 . The system must contain a functional check valve, vacuum relief valve, and low pressure drain appropriately located on the irrigation pipeline to prevent water source contamination from backflow . 7 . The pesticide injection pipeline must contain a functional, automatic, quick-closing check valve to prevent the flow of fluid back toward the injection pump . 8 . The pesticide injection pipeline must also contain a functional, normally closed solenoid-operated valve located on the intake side of the injection pump and connected to the system interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually shut down . 9 . The system must contain functional interlocking controls to automatically shut off the pesticide injection pump when the water pump motor stops . 10 . The irrigation line or water pump must include a functional pressure switch which will stop the water pump motor when the water pressure decreases to the point where pesticide distribution is adversely affected . 11 . Systems must use a metering pump, such as a positive displacement injection pump (e .g ., diaphragm pump) effectively designed and constructed of materials that are compatible with pesticides and capable of being fitted with a system interlock . 12 . Do not apply when wind speed favors drift beyond the area intended for treatment . 8 RESTRICTIONS AND LIMITATIONS Do not apply if rain is expected within 1 hour of application as control can be unsatisfactory . Do not plant rotational crops until 30 days after application of Arrow 2EC unless the crop is listed on the Arrow 2EC label . Do not apply a postemergence broadleaf herbicide within one day following application of Arrow 2EC or reduced grass control can result . Do not use Arrow 2EC on vegetable crops being grown for seed production unless specific use directions are provided . For canola, do not apply more than 6 fl oz of Arrow 2EC (0 .09 lb ai) per acre per season . For clover, flax, mustard seed and radish crops, do not apply more than 16 fl oz of Arrow 2EC (0 .25 lb ai) per acre per season . For all other crops, do not apply more than 32 fl oz of Arrow 2EC (0 .50 lb ai) per acre per season (except where state specific restrictions are noted) . Application on Long Island, New York is restricted to no more than 16 fl oz of Arrow 2EC (0 .25 lb ai) per acre per season . Do not apply more than 8 fl oz/A of Arrow 2EC per application to the following crops: asparagus, brassica vegetables, (head and stem), bean (succulent), carrots, cranberry, cucurbits, flax, fruiting vegetables, (except tomato), garden beet, green onion, herbs, hops, leafy petioles, leafy brassica greens, leafy greens, legume vegetables (edible podded), non-bearing food crops, pea (dry shelled), pea (succulent), root vegetables, safflower, sesame and strawberry . Do not apply more than 6 fl oz /A of Arrow 2EC per application to canola, or mustard seed . For all other crops, do not apply more than 16 fl oz of Arrow 2EC (0 .25 lb ai) per acre per application (except where state specific restrictions are noted) . Exceeding these specifications can result in unacceptable crop injury. Do not apply under conditions of stress . Applying Arrow 2EC under conditions that do not promote active grass growth will reduce herbicide effectiveness . These conditions include drought, excessive water, extremes in temperature, low humidity, and grasses either partially controlled or stunted from prior pesticide applications . Grasses under these kinds of stressful conditions will not absorb and translocate Arrow 2EC effectively and will be less susceptible to herbicide activity . Best perennial grass control can be obtained if rhizomes or stolons are cut up by preplant tillage practices (discing, plowing, etc .) to stimulate maximum emergence of grass shoots . Cultural practices, such as continuous no-tillage in which the perennial grass rhizomes or stolons are not cut up, results in a very staggered, non-uniform weed emergence . Due to this non-uniform weed emergence, make no fewer than two Arrow 2EC applications per season per year at the appropriate weed-growth stage rate under continuous no-till conditions . Grass crops such as corn, rice, sorghum, small grains, or turf, etc . are highly sensitive to Arrow 2EC . While all the vegetable crops on this label have been tested and are tolerant to Arrow 2EC, not all specialty varieties of these crops have been tested . It is advised that, before applying Arrow 2EC to specialty varieties of vegetable crops on this label, crop tolerance be investigated first using a small section of the field . It is possible that injury symptoms can occur . Symptoms may appear as leaf speckling or stunting . Always read and follow the restrictions and limitations for all products whether used alone or in a tank mix . The most restrictive labeling of any product used applies in tank mixtures, including all crop rotational and other crop restrictions . Tank mixes of Arrow 2EC and broadleaf herbicides can result in reduced grass control . If grass regrowth occurs, an additional application of Arrow 2EC may be necessary . 9 AVOID SPRAY DRIFT Do not allow spray from ground or aerial equipment to drift onto adjacent land or crops . When drift may be a problem, do everything possible to reduce spray drift, including: • Do not spray if wind speeds are or become excessive . Do not spray if wind speed is 10 MPH or greater . If sensitive crops or plants are downwind, extreme caution must be used under all conditions . Do not spray if winds are gusty . • Use extreme caution when conditions are favorable for drift (high temperatures, drought, low relative humidity), especially when sensitive plants are located nearby . • Do not apply when a temperature inversion exists . If inversion conditions are suspected, consult with local weather services before making an application . • Further reductions in drift can be obtained by: 1 . Using large droplet size sprays . Do not use nozzles that produce small droplets . Orient nozzles downward and slightly backward as needed to reduce drift for ground applications . 2 . Orienting nozzles straight back with the wind stream, using straight stream orifices for aerial applications . Use the lowest number of nozzles practical with the largest possible orifice size to obtain the minimum 3 GPA volume . Set application height and boom length according to manufacturer’s instructions to minimize drift . 3 . Increasing the volume of spray mixture (for example a minimum of 10 GPA for ground applications) by using higher flow rate nozzles . Using lower pressure with the appropriate nozzle to obtain higher volumes will also reduce drift . 4 . Applying as close to target plants as practical while maintaining a good spray pattern for adequate coverage . Do not apply under conditions involving possible drift to food, forage, or other planting that might be damaged or the crops thereof rendered unfit for sale, use, or consumption. RESISTANCE MANAGEMENT Arrow 2EC is a Group 1 herbicide . Any weed population may contain or develop plants naturally resistant to Arrow 2EC and other Group 1 herbicides . Weed species with acquired resistance to Group 1 may eventually dominate the weed population if Group 1 herbicides are used repeatedly in the same field or in successive years as the primary method of control for targeted species . This may result in partial or total loss of control of those species by Arrow 2EC or other Group 1 herbicides . Repeated use of Arrow 2EC (or similar postemergence grass herbicide with the same mode of action) may lead to the selection of naturally occurring biotypes that are resistant to these products in some grass species . If poor performance occurs and cannot be attributed to adverse weather or application conditions, a resistant biotype may be present . This is most likely to occur in fields where other control strategies such as crop rotation, mechanical removal and other classes of herbicides are not used from year to year . 10
