[Manufactured for:] AMVAC Chemical Corporation 4695 MacArthur Court, Suite 1200 Newport Beach, CA 92660 {Optional marketing claims: Assure® II controls at least 37 annual and perennial grass species, including fall panicum, field sandbur, giant foxtail, johnsongrass (except INZEN A II grain sorghum), shattercane (except INZEN A II grain sorghum) and quackgrass. Assure II can be tank-mixed with several broadleaf herbicides and insecticides. Assure II is a liquid herbicide containing quizalofop-P-ethyl used for control of grasses. Quizalofop-P-ethyl tolerance conferred by the Enlist τcorn trait provides an additional herbicide mode of action for postemergence grass control in corn in Enlist corn. Assure II is a FOP herbicide registered for use on Enlist Corn in the US. Additional Claim: Assure II is a Group 1 herbicide registered for use on Enlist Corn in the US. Additional claim: Assure II herbicide is an authorized herbicide for use with Enlist corn. Additional claim: Assure II herbicide is licensed for use in Enlist corn. Assure II controls volunteer conventional corn and volunteer corn with Roundup Ready® or LibertyLink® traits. The Enlist corn trait confers tolerance to quizalofop-P-ethyl allowing control of grasses and volunteer corn without the Enlist trait. Assure II controls volunteer corn that does not contain the Enlist trait in fields planted with Enlist corn. Assure II in Enlist corn will control volunteer corn that does not contain the Enlist trait. Assure II provides greater volunteer corn control than clethodim in university trials .} PRECAUTIONARY STATEMENTS HAZARDS TO HUMANS AND DOMESTIC ANIMALS DANGER! Causes irreversible eye damage.

ENVIRONMENTAL HAZARDS This pesticide is toxic to fish and invertebrates. Do not appl y directly to water, or to areas where surface water is present, or to intertidal areas below the mean high water mark. Do not contaminate water when cleaning equipment or disposing of equipment washwaters or rinsate. This product may contaminate water through drift of spray in wind. This product has a potential for runoff for several months or more after application. Poorly drained soils and soil s with shallow water tables are more prone to produce runoff that contains this product. A level, well maintained vegetati ve buffer strip between areas to which the product is applied and surface water features such as ponds, streams, and spring s will reduce the potential for contamination of water from rainfall-runoff. Runoff of this product will be reduced by avoidi ng applications when rainfall is forecasted to occur within 48 hours. Sound erosion practices will reduce this product's contribution to surface water contamination.

PHYSICAL AND CHEMICAL HAZARDS Combustible. Keep away from heat, sparks, and open flames. Keep container closed

NON-AGRICULTURAL USE REQUIREMENTS The requirements in this box apply to uses of this product that are NOT within the scope of the Worker protection Standard for agricultural pesticides (40 CFR part170). The WPS applies when this product is used to produce agricultural plants on farms, forests, nurseries, or greenhouses. Weed control in “Non-Agricultural uses” is not within the scope of WPS. Keep unprotected persons out of treated areas until sprays have dried. AGRICULTURAL USE REQUIREMENTS Use this product only in accordance with its labeling and with the Worker prot ection Standard, 40 CFR part 170. This Standard contains requirements for the protection of agricult ural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains re quirements for training, decon tamination, notification, and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this label about personal protective equipment (PPE) and restricted-entry interval. The requirements in this box only apply to uses of this product that are covered by the Worker protection Standard. Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 12 hours.

PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that involves contact with anything that has been treated, such as plants, soil, or water, is: x Coveralls. x Chemical-resistant gloves, made of barrier laminate or Viton ш 14 mils x Shoes plus socks. x Protective eyewear.

Page 4 of 26 ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY ASSURE II is a systemic herbicide that is rapidly absorbed by treated foliage and translocated to the roots and other growing points of the plant. When affected, younger plant tissues become chlorotic/necrotic and eventually die, leaving treated plants stunted and noncompetitive. In general, these symptoms are first observed within 7 to 14 days after application depending on the grass species treated and the environmental conditions. The degree of control and duration of the effect of ASSURE II depend upon the rate used, weed spectrum, weed size and variability, growing conditions at and following treatment, soil moisture, precipitation, tank mixtures, and spray adjuvant used.

Conditions conducive to healthy, actively growing plants optimi ze the performance of ASSURE II. Unacceptable control may occur if ASSURE II is applied to grasses stressed from: x abnormal weather (excessive heat or cold, or widely fluctuating temperatures), x hail damage, x drought, x water saturated soils, x mechanical injury, or x prior herbicide injury. Grasses under these conditions are often less susceptible to herbicide activity. Delay application until the stress passes and weeds and crop resume growth. Allow the crop to fully recover and resume normal growth before applying ASSURE II to crops previously stressed or injured from other pesticide applications. ASSURE II is rainfast 1 hour after application.

APPLICATION INFORMATION USE RESTRICTIONS x Do not feed forage, hay, or straw from treated areas to livestock unless stated otherwise under the specific crop use directions. x Do not apply ASSURE II through any type of irrigation equipment. x Do not contaminate any body of water. x Do not use on lawns, walks, driveways, tennis courts, or similar areas. IMPORTANT PRECAUTIONS Injury to or loss of desirable trees, vegetation, or adjacent susceptible crops may result from failure to observe the following: x Prevent drift of spray to desirable plants (refer to SPRAY DRIFT MANAGEMENT section of this label). x Take all necessary precautions to avoid all direct or indirect contact (such as spray drift) with non-target plants or areas. Most grass crops, including wheat, barley, rye, oats, sorghum, rice, and corn are highly susceptible to ASSURE II. x Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may damage crops other than those included in the crop rotation section. WEED RESISTANCE MANAGEMENT ASSURE II herbicide contains the acti ve ingredient quizalofop-p-ethyl and is a group 1 herbicide based on the mode of action classification system of the Weed Science Society of America. Quizalofop-p-ethyl is in th e class of herbicides known as aryloxphenoxypropionates (FOPs) within the group 1 herbicides that inhibit the enzyme acetyl-CoA carboxylase (ACCase) in weeds. Proactively implementing diversified weed control strategies to minimize selection for weed populations resistant to one or more herbicides is a best practice. A diversified weed manage ment program may include the use of multiple herbicides with different sites of action and overlapping weed spectrum with or without tillage operations and/or other cultural practices. Research has demonstrated that using full-labeled rates and di rections for use is important to delay the selection for resistance. The continued effectiveness of this product depends on the successful implementation of a weed resistance management program. To aid in the prevention of developing weeds resistant to this product, users should: x Scout fields before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes present.

Page 5 of 26 x Start with a clean field, using either a burndown herbicide application or tillage. x Control weeds early when they are relatively small (less than 4 inches). x Apply full rates of ASSURE II herbicide for the most difficult to control weeds in the field at the specified time (correct weed size) to minimize weed escapes. x Scout fields after application to detect weed escapes or shifts in control of weed species. x Control weed escapes before they reproduce by seed or proliferate vegetatively. x Report any incidence of non-performance of this product against a particular weed to your AMVAC representative, local retailer, or county extension agent. x Contact your AMVAC representative, crop advisor, or extension agent to find out if suspected resistant weeds to this MOA have been found in your region. If resistant biotypes of target weeds have been reported, use the application rates of this product specified for your local conditions. Tank mix products so that there are multiple effective sites of actions for each target weed. x If resistance is suspected, treat weed escapes with an he rbicide having a site of acti on other than group 1 and/or use nonchemical methods to remove escapes, as practical, with the goal of preventing further seed production. x Suspected herbicide-resistant weeds may be identified by these indicators: x Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; x A spreading patch of non-controlled plants of a particular weed species; and x Surviving plants mixed with controlled individuals of the same species Additionally, users should follow as many of the following herbicide resistance management practices as is practical: x Use a broad-spectrum soil-applied herbicide with other sites of action as a foundation in a weed control program. x Utilize sequential applications of herbicides with alternative sites of action. x Rotate the use of this product with non-group 1 herbicides. x Avoid making more than two applications of ASSURE II herbicide and any ot her group 1 herbicides within a single growing season unless mixed with an herbicide with a different site of action with an overlapping spectrum for the difficult-to-control weeds. x Incorporate non-chemical weed control practices, such as mechanical cultiv ation, crop rotation, cover crops and weed- free crop seeds, as part of an integrated weed control program. x Use good agronomic principles that enhance crop development and crop competitiveness. x Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. x Manage weeds in and around fields, during and after harvest to reduce weed seed production. INTEGRATED PEST MANAGEMENT This product may be used as part of an Integrated Pest Mana gement (IPM) program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and practices include field scouting or other detection methods, correct target pest identification, popula tion monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area. TANK MIXES It is the pesticide applicator’s responsibility to ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank mixing. Applicators must read and follow the most restrictive directions for use, precautions, and limitations of each product in the tank mixture. Refer to the labels of all tank mix products for information regarding use information (such as rates, timing, application information, and sprayer cleanup) and product precautions and restrictions (especially adjuvants - ASSURE II requires the use of an adjuvant). The most restrictive provisions apply. If those instructions conflict with this label, do not tank mix the herbicide with ASSURE II. AMVAC also recommends that you first consult your state expe riment station, university, or extension agent, Agricultural dealer, or AMVAC representative as to the potential for any adverse interactions (resulting in unacceptable grass control and/or crop injury) before using new herbicid e, insecticide and fungicide mixtures. If no information is available, limit the initial use of ASSURE II and the new herbicide, insecticide or fungicide product to a small area.

Page 6 of 26 Tank Mix Compatibility Testing Always conduct a jar test to evaluate physical compatibility of ASSURE II and other pesticides before applying a particular mixture to listed crops for the first time. Use a clear glass quar t jar with lid and mix the tank mix ingredients in their rela tive proportions. Invert the jar containing the mixture several time s and observe the mixture for approximately 1/2 hour. If the mixture balls-up, forms flakes, sludges, gels, oily film or layers, or other precipitates, it is not compatible. Application with Insecticides and Fungicides ASSURE II may be tank mixed with postemergence fungicides, in secticides and bactericides registered for use in the specific crop. Application with Broadleaf Herbicides For best results, apply ASSURE II alone or in sequenc e with broadleaf herbicide(s). Under arid or stressful environmental conditions, tank mixtures with broadleaf herbicides may reduce control of some grass species. Activity of the postemergence broadleaf herbicide in the tank mixture is not affected. Split Applications with Postemergence Broadleaf Herbicides ASSURE II applied immediately prior to or following an ap plication of a postemergence broadleaf herbicide may reduce control of some grasses. For best results apply ASSURE II at least 1 day before or 7 days after postemergence broadleaf herbicides.

SPOT/SMALL AREA SPRAY INSTRUCTIONS To spot treat small areas of annuals (i.e., volunteer corn) or perennials (i.e., rhizome johnsongrass) Use a 0.375% volume/volume (v/v) solution of ASSURE II and water.

Do not exceed the maximum specified rate/acre/season for the crop that is going to be planted when additional applications are made as spot treatment or small area treatment. Cultivation A timely cultivation may be necessary to control suppressed weeds, weeds that were beyond the maximum size at application, or weeds that emerge after an application of ASSURE II.

Cultivation up to 7 days before the postemergence application of ASSURE II may decrease weed control by pruning weed roots, placing the weeds under stress, or covering the weeds with soil and preventing coverage by ASSURE II . Optimum timing for cultivation is 7 - 14 days after a postemergence application of ASSURE II.

Agricultural Uses ASSURE II herbicide is a selective herbic ide that controls annual and perennial grasses in canola, carinata, crambe, cotton (cottonseed subgroup 20C), crops grown for seed, eucalyptus, d ry beans (including Chickpea), dry and succulent peas, flax (flaxseed), fruit, pome crop group 11-10 (except New York state), fruit, small vine climbing, except fuzzy kiwifruit crop subgroup 13-07F (except New York state), fruit, stone crop gr oup 12-12 (except New York state), hybrid poplar plantings, lentils, mint (spearmint and peppermint), pennycress, pinea pple, rapeseed subgroup 20A (inc ludes borage, canola, crambe, gold of pleasure [camelina], cuphea, echium, Hare's ear mustard, oil radish, poppy seed, rapeseed, sesame, sweet rocket, cultivars, varieties, and/or hybrids of these), ryegrass grown for seed, snap beans, INZEN™ A II grain sorghum, soybeans, sugarbeets, sunflower (subgroup 20B), Enlist™ field corn and non-crop areas. ASSURE® II is also registered for control of annual and perennial grasses in alfalfa, onion, carrot, garlic, Swiss chard, spinach, radish, Chinese cabbage, and red beets grown specifically under contract as non-food/non feed crops for seed production only.

Page 7 of 26

ASSURE II does not control sedges or broadleaf weeds. ASSURE II controls the grasses listed in the “Weeds Controlled and rate Selection” chart when applied at specified rates and timings. ASSURE II will control emerged grasses. Subsequent flushes of grasses require additional treatment. See "use restrictions" portion of the label before using. Follow all use directions and restrictions listed for the specific crop.

Non-Agricultural Uses Non-Crop Areas ASSURE II is registered for postemergence control of certain grasses on non-crop sites including fence rows, roadsides and equipment storage areas. x Apply by ground application equipment only. x DO NOT apply by aerial application. x For paved areas, apply as spot/small area treatments only (see Spot/Small Area Spray instructions section). x Make a single application of ASSURE II at a rate of 12 to 16 fl oz/A (0.083 - 0.11 lb ai/A) to actively growing grasses. Non-Crop Areas - to aid in establishment of Wildflowers x Since ASSURE II controls many grasses but not most broadleaf plants, it may be used to enhance establishment and growth of certain broadleaf plants on non-crop sites (that is , plants identified as “wildflowers” such as indian blanket, cone flowers, bachelor button, dwarf co rnflower, coreopsis, white yarrow, oxey e daisy, dames-rocket, blue flax, evening primrose, blackeyed-susan, marigold, impatiens, bluebonnet, Indian paintbrush, verbena, gaillardia, chrysanthemum, catchfly and scarlet pimpernel). x Make a single application of ASSURE II at a rate of 5 to 12 fl oz/A (0.034 - 0.083 lb ai/A). Refer to the ‘’ Weeds Controlled and Rate Selection’’ table for specific application rates. Do not apply more than 12 fl oz/A (0.083 lb ai/A) per year. Application Timing

Sequential Applications Do not exceed the maximum use rates listed under the directions for each specific crop. Annual Grasses In the event of a subsequent flush of grass, or regrowth of pr eviously treated grass occurs, a second application of ASSURE II may be applied unless stated otherwise. Select the appropriat e rate for the grassy weed from the “Weeds Controlled - rate selection” chart. Perennial Grasses If perennial grasses regrow, reapply ASSURE II at 6-7 fl oz/A of product, unless stated otherwise. Do not exceed the maximum use rates listed under each crop. Spray Adjuvants Applications of ASSURE II must include either a crop oil concentrate or a nonioni c surfactant. Consult local AMVAC fact sheets, technical bulletins, and service policies prior to using ot her adjuvant systems. If another herbicide is tank mixed wit h ASSURE II to increase the weed spectrum, select adjuvants authorized for use with both products. Products must contain only EPA-exempt ingredients. Petroleum Crop Oil Concentrate (COC) x Petroleum-based crop oil concentrates are the most effective adjuvant type with ASSURE II. x Apply petroleum-based crop oi l concentrate at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions. Note – In soybean and sunflower, up to 2% v/v may be used based on local recommendations. x Oil adjuvants must contain at least 80% phytobland, petroleum (mineral) or modified vegetable seed oil with at least 15% surfactant emulsifiers. x For aerial application apply 0.5% v/v (2 quarts product per 100 gallons spray solution). Nonionic Surfactant (NIS) x Apply at 0.25 % v/v (1 quart of product per 100 gallons spray solution). Crop and Non-Crop Uses Apply ASSURE II to young, actively growing grasses according to th e rate chart that follows. If a field is to be irrigated, app ly ASSURE II after the irrigation. Applications made to grasses that are larger than the sizes listed in the rate charts or to grasses under stress may result in unsatisfactory control.

Page 8 of 26 x Surfactant products must contain at least 80% nonionic surfactant. Ammonium Nitrogen Fertilizer x An ammonium nitrogen fertilizer may be added to the spra y mixture, in addition to crop oil concentrate or nonionic surfactant, but is not required to optimize performance of this product. x Use 2 quart/A of a high-quality urea ammonium nitrate (UAN), such as 28%N or 32%N, or 2 lb/A of a spray-grade ammonium sulfate (AMS). Use 4 qt/A UAN or 4 lb/A AMS under arid conditions. x Do not use liquid nitrogen fertilizer as the total carrier solution. Special Adjuvant Types x Combination adjuvant products may be used at doses that provide the required amount of NIS, COC, MSO and/or ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions. x In addition to the adjuvants specified above, other adjuvant types may be used if they provide the same functionality and have been evaluated and approved by AMVAC Product Development.

For control of other weeds, it may be tank mixed with glyphosate as follows: x Apply ASSURE II at a rate of 4 fl oz/A for up to 12 inch volunteer corn, 5 fl oz/A for 12- 18 inch corn and 8 fl oz/A ASSURE II for 18-30 inch corn, tank mixed with a labeled rate of glyphosate. x A nonionic surfactant or petroleum based crop oil concentrate adjuvant must be included. Refer to the Spray Adjuvants section in this label for adjuvant preference, rates, and additional use information. Rhizome Johnsongrass - South East States For control of rhizome johnsongrass in the states of Alabama, Arkansas, Florida, Georgia, Loui siana, Maryland, Mississippi, Tennessee, Virginia, and West Virginia, a reduced rate of ASSURE II may be used if applied in a sequential application program as follows:

1. Apply ASSURE II at 5 fl oz/A when johnsongrass is 10-24 inches tall.
2. Apply ASSURE II a second time at 5 fl oz/A wh en johnsongrass regrowth is 6-10 inches tall. Do not apply ASSURE II in a tank mix with postemergence broadleaf herbicides when using this reduced rate, sequential application program. Do not exceed the ma ximum specified rate/acre/season for the crop that is going to be planted when additional applications are made to control rhizome johnsongrass. Rhizome Johnsongrass ASSURE II herbicide will provide control of weeds in fallow, including emerged rhizome and seedling Johnsongrass. Note that, when applied at specified rates and timings to control grass weeds, ASSURE II herbicide will provide control of emerged grasses only. Subsequent flushes of grasses require additional treatment. Apply ASSURE II herbicide for control of seedling and rhizome Johnsongrass at the range indicated. x Apply ASSURE II at 8 fl oz/A when seedling johnsongrass is 2 - 6 inches tall. x Apply ASSURE II at 12 fl oz/A when rhizome johnsongrass is 12-16 inches tall. x If rhizome Johnsongrass regrows, reapply ASSURE II at 8 fl oz/A when Johnsongrass regrowth is 6-10 inches in height. Tank mixes of ASSURE II with postemergence broadleaf herbicides may result in reduced grass control. If grass control is reduced, an additional application of ASSURE II ma y be required after grass plants begin regrowth.

Enlist Field Corn- These directions are for use only on Enlist field corn. Information on crop varieties containing this trait may be obtained from your seed supplier. In-Field Buffer: The applicator must always maintain a 36-foot, downwind buffer between the last treated row and the nearest downwind field edge (in the direction the wind is blowing).The following areas may be included in the buffer distance calculation when directly adjacent to the treated field edge(s): x Roads, paved or gravel surfaces. x Planted agricultural fields (except crops listed in the "Susceptible plants" section). x Agricultural fields that have been prepared for planting. x Areas covered by the footprint of a building, shadehouse, g reenhouse, silo, feed crib, or other man-made structure with walls and/or a roof. To maintain the required downwind buffer zone: x Measure the wind direction prior to the start of any swath that is within 36 feet of a sensitive area. x No application swath can be initiated in or into an area that is within 36 feet of a sensitive area if the wind direction is towards the sensitive area. Susceptible Plants: Do not apply under circumstances where spray drift may occur to food, forage, or other plantings that might be damaged or crops thereof rendered unfit for sale, use or consumption. Do not allow contact of herbicide with foliage, green stems, exposed non-woody roots of crops, desirable plants; including tr ees, because severe injury or destruction may result. Small amounts of spray drift that may not be visible may injure suscep tible plants. Most grass crops, including wheat, barley, rye, oats, sorghum, rice, and non - Enlist corn are highly sens itive to ASSURE II. Before making an application, please refer to your state’s sensitive crop registry (if available) to identify any commercial specialty or certified organic crops that may be located nearby. Resistance Management for Enlist Field Corn: The following steps are provided to aid in the prevention of developing weeds resistant to this product: x Scout field before application to ensure herbicides and rates will be appropriate for the weed species and weed sizes present. x Apply the maximum specified labeled use rate of this product for the most difficult to control weed in the field at the specified time (correct weed size) to minimize weed escapes. x Scout field after application to detect weed escapes or shifts in weed species. x Report any incident of non-performance of this product on a targeted weed species to your AMVAC retailer, representative, or call 1-888-462-6822 x If resistance is suspected in targeted weed species, treat weed escapes with an herbicide having a mechanism of action other than group 1 and/or use non-chemical methods to remove escapes, as practical, with the goal of preventing further seed production. Report suspected resistance to your AMVAC retailer, representative, or call 1-888-462-6822. Suspected Resistance: Indicators of suspected herbicide resistance incl ude (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of uncontrolled plants of a particular weed species; and (3) su rviving plants mixed with controlled individuals of the same species. Likely resistant weeds are assumed to be present if any of these criteria are met. Additionally, users should follow as many of the following herbicide-resistance management practices as practicable: x Use a broad-spectrum, soil-applied herbicide with other mechanisms of action as a foundation in a weed control program. x Utilize sequential applications of herbicides with alternative mechanisms of action. x Rotate the use of this product with non-group 1 herbicides. x Incorporate non-chemical weed control practices, such as mechanical cultivation, crop rotation, cover crops, and weed- free crop seeds, as part of an integrated weed control program.

Page 16 of 26 x Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant weeds. x Avoid using any other group 1 herbicides within a sing le growing season unless in conjunction with another mechanism- of-action herbicide with overlapping spectrum. x Manage weeds in and around fields, during and after harvest to reduce weed seed production. Contact your local sales representative, crop advisor, or extens ion agent to find out if suspected resistant weeds to group 1 herbicides have been found in your regions. If resistant biotyp es of target weeds have been reported, use the application rates of this product specified for your local conditions.

Ground Application Broadcast Application x When applying by ground, use spray nozzles that will deliv er medium or larger spray droplets as defined in the American Society of Agricultural and Biological Engin eers (ASABE) standard ANSI/ASAE S572.1 (March 2009). (See Spray Drift Management section for additional information). x Use flat fan or hollow cone nozzles at 25-60 psi. x Do not use flood, rain drop, whirl chamber, or any other nozzle types that produce coarse, large spray droplets. In addition, do not use controlled droplet applicator (CDA) type nozzles as poor weed control or excessive spray drift may result. x Use a minimum of 10 gal/A of water in non-arid areas. x Use a minimum of 15 gal/A of water in arid areas. x For all crops except pineapple: Do not exceed 40 gal of wate r per acre. Refer to pineapple section for specified spray water volumes. x Increase spray volume and pressure as weed or crop density and size increase. Band Application x Because band application equipment sprays a narrower ar ea than broadcast application equipment, calibrate equipment to use proportionately less spray solution. x To avoid crop injury, carefully calibrate the band applicator not to exceed the labeled rate. x Carefully follow the manufacturer’s instructions for nozzle type, nozzle orientation, distance of the nozzles from the crop and weeds, spray volumes, calibration, and spray pressure.

Aerial Application x Use spray nozzles that will deliver coarse or larger spray drop lets as defined in the American Society of Agricultural and Biological Engineers (ASABE) standard ANSI/ASAE S572.1 (March 2009). (See Spray Drift Management section for additional information). x Use nozzle types and arrangements that provide op timum spray distribution and maximum coverage. x Use a minimum of 3 gal of water per acre in non-arid areas. x Use a minimum of 5 gal of water per acre in arid areas. MIXING INSTRUCTIONS

1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of ASSURE II. If ASSURE II and a tank mix partner are to be applied together, consult the tank mix partner label for information on which should be added first (normally granules and powders are added first).
3. Continue agitation until the ASSURE II is fully dispersed, at least 5 minutes.
4. Once the ASSURE II is fully disp ersed, maintain agitation and continue filling tank with water.
5. As the tank is filling, add the required volume of spray additives, always add these to the spray tank last.
6. Apply ASSURE II spray mixture within a reasonable period of time of mixing to avoid product degradation (24 to 48 hrs). If the spray mixture stands for any period of time, thoroughly re-agitate before using. SPRAYER CLEANUP The spray equipment must be cleaned before ASSURE II is sprayed. Follow the cleanup procedures specified on the labels of the previously applied products. If no directions are provided, follow the six steps outlined in After Spraying ASSURE II. It i s very important that any buildup of dried pesticide deposits wh ich have accumulated in the application equipment be removed prior to spraying ASSURE II. Steam-cleaning spray tanks to facilitate the removal of any caked deposits of previously applied products will help prevent accidental crop injury. After Multiple Loads of ASSURE II herbicide At the end of each day after multiple loads of ASSURE II herbic ide are applied, rinse the interi or of the tank with fresh water and then partially fill to flush boom and hoses. This will preven t the buildup of dried pesticide deposits which can accumulate in the application equipment.

Page 19 of 26 After Spraying ASSUREയIIയand Before Spraying Susceptible Crops and Crops Other Than Those Listed in the Crop Rotation Section

x Drain tank; thoroughly rinse spray tanks, boom, and hoses with clean water. Loosen and physically remove any visible deposits. x Fill the tank with clean water and 1 gal of household ammonia* (contains 3% active) for every 100 gal of water. Flush the hoses, boom, and nozzles with the cleaning solution. Then add more water to completely fill the tank. Circulate the cleaning solution through the tank and hoses for at least 15 mi n. Flush the hoses, boom, and nozzles again with the cleaning solution, and then drain the tank. x Remove the nozzles and screens and clean separately in a bucket containing cleaning agent and water. x Repeat step 2. x Rinse the tank, boom, and hoses with clean water. x If only Ammonia is used as a cleaner, the rinsate solution may be applied back to the crop(s) recommended on this label. Do not exceed the maximum labeled use rate. If other cleaners are used, consult the cleaner label for rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility. *Equivalent amounts of an alternate-strength ammonia solution or an AMVAC-approved cleaner can be used in the cleanout procedure. Carefully read and follow the individual cleaner in structions. Consult your Ag dealer, applicator, or AMVAC representative for a listing of approved cleaners. Notes: x CAUTION: Do not use chlorine bleach with ammonia as dangerous gases will form. Do not clean equipment in an enclosed area. x Steam-cleaning spray tanks is recommended prior to pe rforming the above cleanout procedure to facilitate the removal of any caked deposits. x When ASSURE II is tank mixed with other pesticides, all cleanout procedures should be examined and the most rigorous procedure should be followed. x In addition to this cleanout procedure, all precleanout guidelines on subsequently applied products should be followed as per the individual labels. x Where routine spraying practices include shared equipm ent frequently being switched between applications of ASSURE II and applications of other pesticides to ASSURE II-sensitive crops during the same spray season, it is recommended that a sprayer be dedicated to ASSURE II to further reduce the chance of crop injury. SPRAY DRIFT MANAGEMENT The interaction of many equipment and weather-related factors determines the potential for spray drift. The applicator is responsible for considering all these factors when making application decisions. AVOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR. Importance of Droplet Size The most effective way to reduce drift potential is to apply coar se or larger spray droplets as defined by the ASABE standard ANSI/ASAE S572.1 (March 2009). The best drift management strate gy is to apply the largest dr oplets that provide sufficient coverage and control. The presence of sensitive species nearby, the environmental conditions, and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL, BUT WILL NOT PREVENT DRIFT IF APPLICATIONS ARE MADE IMPROPER LY OR UNDER UNFAVORABLE ENVIRONMENTAL CONDITIONS! See Wind, Temperature and Humidity, and Temperature Inversions sections of this label. Controlling droplet Size - Ground Boom Volume - Increasing the spray volume so that larger droplets are produced will reduce spray drift. use the highest practical spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate. Pressure - use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet size. Spray Nozzle - use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce drift. Controlling droplet Size - aircraft To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately following applications of ASSURE II as follows:

Page 20 of 26 Number of Nozzles - using the minimum number of nozzles with the highest flow rate that provide uniform coverage will produce a coarser droplet spectrum. Nozzle Orientation - orienting nozzles in a manner that minimizes the effects of air shear will produce the coarsest droplet spectra. For some nozzles such as solid stream, pointing the no zzles straight back parallel to the airstream will produce a coarser droplet spectrum than other orientations. Nozzle Type - Solid stream nozzles (such as disc and core with sw irl plate removed) or other low drift nozzles produce the coarsest droplet spectra. Pressure - Selecting the pressure that produces the coarsest droplet spectrum for a particular nozzle and airspeed reduces spray drift potential. For some nozzle types such as solid st reams, lower pressures can produce finer droplet spectra and increase drift potential. Boom Length (Aircraft) and Application Height x Boom Length (aircraft) - using shorter booms decreases drift potential. Boom lengths are expressed as a percentage of an aircraft’s wingspan or a helicopter’s rotor blad e diameter. Shorter boom length and proper positioning can minimize drift caused by wingtip or rotor vortices. x Application Height (aircraft) - Applications made at the lowest height that are consistent with pest control objectives and the safe operation of the airc raft will reduce the potential for spray drift. x Application Height (ground) - Applications made at the lowest height cons istent with pest control objectives, and that allow the applicator to keep the boom level with the a pplication site and minimize bounce, will reduce the exposure of spray droplets to evaporation and wind, and reduce spray drift potential. Wind Apply when wind speeds are less than 15 mph. The wind speed range for optimum performance is between 3 and 10 mph. At wind speeds less than 3 mph temperature inversions may exist, and at wind speeds above 10 mph spray patterns may be compromised. However, many factors, including droplet size and equipment type determine drift potential at any given wind speed. AVOID GUSTY OR WINDLESS CONDITIONS. Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. Temperature and humidity Setting up equipment to produce larger droplets to compensate for droplet evaporation can reduce spray drift potential. Droplet evaporation is most severe when conditions are both hot and dry. Temperature inversions Do not apply during surface temperature inversions. Drift potent ial is high during a surface temperature inversion. Surface temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain close to the ground and move laterally in a concentrated cloud. Surface inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. Th ey begin to form as the sun sets and often continue into the morning. Mist or fog may indicate the presence of an inve rsion in humid areas. Inversions may also be identified by producing smoke and observing its behavior. Smoke that remains cl ose to the ground, or moves laterally in a concentrated cloud under low wind conditions indicates a surface inversion. Smoke that moves upward and rapidly dissipates indicates good vertical air mixing. Shielded Sprayers Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the res ponsibility of the applicator to verify that the shields are minimizing drift potential and not interfering with uniform deposition of the product. Sensitive Areas Making applications when there is a sustained wind moving away from adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is an effective way to minimize the effect of spray drift. DRIFT CONTROL ADDITIVES Using product compatible drift control additives can reduce drift po tential. When a drift control additive is used, read and carefully observe cautionary statements and a ll other information on the additive’s labe l. If using an additive that increases viscosity, ensure that the nozzles and other application equipm ent will function properly with a viscous spray solution. Preferred drift control additives have been certified by the Chemical producers and Distributors Association (CPDA).

Page 21 of 26 Upwind Swath Displacement When applications are made with a crossw ind the swath will be displaced downwind.
