ENGINEERING CONTROLS STATEMENT When handlers use enclosed cabs or aircraft in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides [40 CFR 170.240(d)(4-6)], the handler PPE requirements may be reduced or modified as specified in the WPS. Pilots must use an enclosed cockpit that meets the requirements listed in the WPS for agricultural pesticides [40 CFR 170.240(d)(6»). For containers of 5 gallons or more: A mechanical system (such as probe and pump or spigot) must be used for transferring the contents of this container. If the contents of nonrefillable pesticide container are emptied, the probe must be rinsed before removal. If the mechanical system is used in a manner that meets the requirements listed in the WPS for agricultural pesticides [40 CFR 170.240(d)(4)], the handler PPE requirements may be reduced or modified as specified in the WPS. USER SAFETY RECOMMENDATIONS Users should: 1) Wash hands before eating, drinking, chewing gum, using tobacco, or using the toilet. 2) Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on clean clothing. If pesticide gets on skin, wash immediately with soap and water. 3) Remove PPE immediately after handling this product. As soon as possible, wash thoroughly and change into clean clothing. ENVIRONMENTAL HAZARDS This product is toxic to fish and aquatic invertebrates. Do not apply directly to water, to areas where surface water is present or to intertidal areas below the mean high water mark. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas and nontarget plants. Do not contaminate water when disposing of equipment washwaters or rinsate. This chemical has properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination. Application around a cistern or well may result in contamination of drinking water or groundwater. Fish breathe dissolved oxygen in the water and decaying weeds also use oxygen. When treating continuous, dense weed masses, it may be appropriate to treat only part of the infestation at a time. For example, apply the product in lanes separated by untreated strips that can be treated after vegetation in treated lanes has disintegrated. During the growing season, weeds decompose in a 2 to 3 week period following treatment. Begin treatment along the shore and proceed outwards in bands to allow fish to move· into untreated areas. Waters having limited and less dense weed infestations may not require partial treatments. Mixing and Loading: Most cases of groundwater contamination involving phenoxy herbicides such as 2,4-0 have been associated with mixinglloading and disposal supplies. Use closed systems for mixing and transferring this pesticide will reduce the probability of spills. Placement of the mixinglloading equipment on an impervious pad to contain spills will help prevent groundwater contamination. Page 3 of 28

( DIRECTIONS FOR USE It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Read all directions for use carefully before applying. Do not apply this product in a way that will contact workers or other person, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation. AGRICULTURAL USE REQUIREMENTS Use this product only in accordance with its labeling and with the Worker Protection Standard (WPS), 40 CFR Part 170. This standard contains the requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers or agricultural pesticides. It contains requirements for training, decontamination, 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 in the WPS. Do not enter or allow worker entry into treated areas during the restricted entry interval (REI) of 48 hours. PPE required for early entry to treated areas that is permitted under the WPS and that involves contact with anything that has been treated such as plants, soil, or water is: Coveralls, shoes plus socks, chemical-resistant gloves made of any waterproof material, and protective eyewear. 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 (WPS) for agricultural pesticides (40 CFR Part 170). The WPS applies when this product is used to produce agricultural plants on farms, forests, nurseries or greenhouses. . Entry Restrictions for Non-WPS Uses: When this product is applied in the rangeland and established pastures not harvested for hay or seed; noncropland areas, when tree injection method only in forest sites, and when applied in aquatic areas, do not enter or allow people (other than applicator) or pets on treatment area during application. Do not enter treated areas until sprays have dried. USE INFORMATION D-AMINE 4 Herbicide is intended for selective control of many broad leaf weeds in certain crops (cereal grains, corn, grain sorghum, soybeans and sugarcane), orchard floors (pome fruits, including apples and pears, stone fruits, nut orchards and pistachios), fallow cropland, forests, grass pastures, rangeland, Conservation Reserve Programs acres, ornamental turf (including turf grown for sod or seed), noncropland and aquatic areas. Apply this product as a water or oil-water spray during warm weather when target weeds or woody plants are actively growing. Application under drought conditions will often give poor results. Use low spray pressure to minimize drift. Generally, the lower dosages specified on this label will be satisfactory for young, succulent growth of susceptible weed species. For less susceptible species and under conditions where control is more difficult, use the higher specified rates. Deep-rooted perennials such as Canada thistle and filed bindweed and many woody plants usually require repeated applications for satisfactory control. Consult your State Agricultural Experiment stations or Extension Service Weed SpeCialist for recommendations from this label that best fit local conditions. USE PRECAUTIONS AND RESTRICTIONS Be sure that this product conforms to all application regulations. Page 4 of 28

( Chemigation: Do not apply this product through any type of irrigation system. Exc.essive amounts of 2.4-0 in the soil may temporarily inhibit seed germination of plant growth. " , Do not apply this product in a way that will contact workers or other persons. either directly or through drift. Only protected handlers may be in the area during application. Spray Drift Management A variety of factors including weather conditions (e.g., wind direction. wind speed, temperature, relative humidity) and method of application (e.g .• ground, aerial, airblast) can influence pesticide drift. The applicator must evaluate all factors and make appropriate adjustments when applying this product. Droplet Size When applying sprays that contain 2,4-0 as the sole active ingredient, or when applying sprays that contain 2,4-0 mixed with active ingredients that require a Coarse or coarser spray, apply only as a Coarse or coarser spray (ASAE standard 572) or'a volume mean diameter of 385 microns or greater for spinning atomizer nozzles. When .applying sprays that contain 2,4-0 mixed with other active ingredients that require a Medium or more fine spray, apply only as a Medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for spinning atomizer nozzles. Wind Speed Do not apply atwind speeds greater than 15 mph. Only apply this product if the wind direction favors on-­ target deposition and there are not sensitive areas (including, but not limited to, residential areas. bodies of water, known habitat for nontarget species, nontarget crops) within 250 feet downwind. If applying a Medium spray, leave one swath unsprayed at the downwind edge of the treated field. Temperature Inversions If applying at wind speeds less than 3 mph, the applicator must determine if: a) conditions of temperature inversion exist, or b) stable atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable atmospheric conditions. 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. Susceptible crops include, but are not limited to, cotton, okra. flowers. fruit trees. grapes (in growing stage). fruit trees (foliage). soybeans (vegetative stage). ornamentals. sunflowers.'tomatoes. beans. and other vegetables. or tobacco. Small , amounts of spray drift that may not be visible may injure susceptible broadleaf plants. Other State and Local Requirements Applicators must follow all state and local pesticide drift requirements regarding application of 2,4-0 - herbicides. Where states have more stringent regulations. they must be observed. Equipment , , All aerial and ground application equipment must be properly maintained and calibrated using apflropriate carriers or !:!urrogates. Aerial Application The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter. Page 50f28

Release spray at the lowest height c9nsistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet above the crop canopy unless a greater height is required for aircraft safety. This requirement does not apply to forestry or rights-of-way applications. When applications are mad~ with a crosswinq, the swath will be displaced downwind. The applicator must compensate for his by adjusting the path of the aircraft upwind. Ground Boom Application Do not apply with a nozzle height greater than 4 feet above the crop canopy. Mxing Mix this product only with water, unless otherwise directed on this label. Add about half the water to the mixing tank, then add this product with agitation, and finally the rest of the water with continuing agitation. Note: Adding oil, wetting agent, or other surfactant to the spray mixture may increase-effectiveness on weeds, but also may reduce selectivity to crops resulting in crop damage. Tank Mixing: When tank mixing, read and follow the label of each tank mix product used for precautionary statements, directions for use, weeds controlled, and geographic and other restrictions. Use in accordance with the most restrictive of label limitations and precautions. No label dosages should be exceeded. Do not tank mix this product with any product containing a label prohibition against tank mixing , with2,4-D. Tank Mix Compatibility Testing: Ajar test is recommended prior'to tank mixing to ensure compatibility of . this product and other pesticides. Use a clear glass quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the mixture several times and observe the mixture for approximately 1/2 hour. If the mixture balls-up, forms flakes, sludges, jells, oily films or layers, or other preCipitates, it is not compatible and the tank. mix combination should n,ot be used. Mixing with Liquid Nitrogen Fertilizer This product may be combined with liquid nitrogen fertilizer suitable for foliar application to accomplish broadleafweed control and fertilization of corn, small grains or pastures in a single opration. Use this product in accordance with recommendations for these crops provided in this label. Use liquid fertilizer at rates recommended by the supplier or Extension Service Specialist. Test for mixing compatibility as describe above before mixing in spray tank. A compatibility aid such as Unite or Compex may be needed in·some situations. Compatibility is best with liquid fertilizer solutions containing only nitrogen. Mixing with N-P-K solutions may not be satisfactory, even with the addition of a compatibility aid. Pre-mixing 1 part of this product with up to 4 parts water may help in situations when mixing difficulty occurs. . . Fill the tank about half full with the liquid fertilizer, then add the required amount of this product with agitation. Maintain agitation and complete filling the tank with liquid fertilizer. Apply immediately and continue agitation in spray tank during application. Do not store the spray mixture. Application during very cold weather (ner freezing) is not advisable. . Sprayer Clean-Out To avoid injury to desirable plants, equipment used to apply·this product should be thoroughly cleaned before re-use or applying other chemicals.

1. Rinse and flush application equipment thoroughly after use at least three times with water. Dispose of all rinse water by application to treatment area or apply to non-cropland area away Page 6 of 28

from water supplies. 2. During the second rinse, add 1 qt of household ammonia for every 25 gallons of water. Circulate the solution through the .entire system so that all internal surfaces are contacted (15-20 min). Let the solution stand for several hours, preferably overnight. 3. Flush the solution out of the spray tank through the boom. 4. Rinse the system twice with clean water, recjrculating and draining each time. 5. Remove nozzles and screens and clean separately. 6, If equipment is to be used to apply another pesticide or agricultural chemical to a 2,4-0 susceptible crop, additional steps may be required to remove all traces of 2,4-0, including cleaning of disassembled parts and replacement of hoses or other fittings that may contain absorbed 2,4':'0. Application Apply with calibrated air or ground equipment using sufficient spray volume to provide adequate coverage of target weeds' or as otherwise directed in specif,ic' use directions. For broadcast application, use a spray volume of 3 or more gallons per acre by air and 10 or more gallons per acre for ground equipment. Where states have regulations which speify minimum spray volumes, they should be observed. In general, spray volume should be increased as crop canopy, height and weed density increase in order to obtain adequate spray coverage. 06 not apply less than 3 gallons total spray volume per acre. Rate Ranges and Application Timing Generally, the lower dosages given will be satisfactory for young, succulent growth of sensitive weed species. For less sensitive speCies and under conditions where control is more difficult, the higher dosages will be needed. Apply this product during warm weather when weeds are young and actively growing. Spot Treatments To prevent misapplication, spot treatments should be applied with a calibrated boom or with hand sprayers using a fixed spray volume per 1,000 sq ft as indicated below. Hand-Held Sprayers: Hand-held sprayers may be used for spot applications of this product. Care should be taken to apply the spray uniformly and·at a rate equivalent to a broadcast application. Application rates in the table are based on the application rate for an area of 1,000 sq ft. Mix the amount of this I product (fJ OZ or ml) corresponding to the desired broadcast rate in 1 to 3 gallons of spray. To calculate . the amount of this product required for larger areas, multiply the table value.(ft OZ or ml) by the thousands of sq ft to. be treated.

Due to potential phytotoxicity considerations, the following restrictions are applicable: If treated water is intended to be used to irrigate or mix sprays for plants grown in commercial nurseries and gr~enhouses; and other plants or crops that are not labeled for direct treatment with 2,4-0, the water must not be used unless one of the following restrictions has been observed: i. A setback distance from functional water intake(s) of greater than or equal to 600 ft. was used for the application, or, ii. A waiting period of 7 days from the time of application has elapsed, or,
2. An approved assay indicates that the 2,4-0 concentration is 100 ppb (0.1 ppm) or less at the water intake. Wait at least 3 days after application before initial sampling at water intake.
3. Drinking water (potable water): A. Consult with appropriate state or local water authorities before applying this product to public waters. State or local agencies may require permits. The potable water use restrictions on this label are to ensure that consumption of water by the public is allowed only when the concentration of 2,4-0 in the water is less than the MCl (MaXimum Contaminant level) of 70 ppb. Applicators should consider the unique characteristics of the treated waters to assure that 2,4-0 concentrations in potablewater do not exceed 70 ppb at the time of consumption. '-s. For floating and emergent weed applications, the drinking water setback distance from functioning potable water intakes is greater than or equal to 600 ft .. C. If no setback distance of greater than or equal to 600 ft. is used for applicat!on, applicators or the authorizing organization must provide a drinking water notification prior to a 2,4-0 application to the party responsible for public water supply or to individual private water uses. Notification to the party responsible for a public water supply or to individual private water users must be done in a manner to assure that the party is aware of the water use restrictions when this product is applied to potable water. The following is an, example of a notification via posting, but other methods of notification which convey the above restrictions may be used and may be required in some cases under state or local law or as a condition of a permit. Example: Posting notification should be located every 250 feet including the shoreline of the treated area and up to 250 feet of shoreline past the application site to include immediate publi,c access points. Posting must include the day and time of application. Posting may be removed if analysis of a sample collected at the intake 3 or more days following application shows that the Page 25 of 28

concentration in the water is less than 70 ppb (100 ppb for irrigation or sprays), or after 7 dl;lys following application, whichever occurs first. 'Text o~ notification: Wait 7 days before diverting functioning surface water intakes from the treated aquatic site to use as drinking water, irrigation, or sprays, unless water at functioning drinking water intakes is tested at least 3 days after application and is demonstrated by assay to contain not more than O ppb 2,4-0 (100 ppb for irrigation or sprays). Application Date: Tme: D. Following each application of this product, treated water must not be used for drinking water unless one of the following restrictions has been observed: i. A setback distance from functional water intake(s} of greater th.an or equal to 600. ft. was used for the application, or, ii. A waiting period of at least 7 days from the time of application has elapsed, or, iii. An approved assay indicates that the 2,4-D concentration is 70 ppb (0.07 ppm) or less at the water intake. Sampling for drinking water analysis should occur no soonefthan 3 days after 2,4-D application. Analysis of samples must be completed by a .laboratory that is certified under the Safe Drinking Water Act to perform drinking water analysis using a currently approved 'version of analytical Method Number 515, 555, other methods for 2,4-D as may be listed in Title 40 CFR, Part 141.24, or Method Number 4015 (immunoassay of 2,4-D) from U.S. EPA Test Methods for Evaluating Solid Waste SW-846. E. Note: EXisting potable water intakes that are no longer in use, such as those replaced by a connection to a municipal water system or a potable water well, are not considered to be· functioning potable water intakes. . F. Drinking water setback distances do not apply to terrestrial applications of 2,4-0 adjacent to water bodies with potable water intakes. Precautions and Restrictions for Aquatic Use: • Do not treat areas that are riot infested with aquatic weeds. • Wind Speed: Do not apply when wind speed is at or above 10 mph when making ground or surface applications. Do not aerially apply when wind speed is greater than 5 mph. Wind speed restrictions do not apply for subsurface applications used in submerged aquatic weed control programs .. • Dissolved Oxygen Ratio: Fish require oxygen dissolved in water for life processes and a favorable water­ oxygen ratio must be maintained. Decaying weeds use up dissolved oxygen in water. Fish kill resulting from decaying plant material can be prevented by: (1) treating the entire area when the weed mass is sparse and the rate of decomposition will not be sufficient to disturb the water-oxygen ratio; or (2) If application is delayed until there is a dense weed mass, at no more than one-half of a lake or pond at one time. For large bodies of weed-infested water, apply product in lanes, leaving buffers strips at least 100 feet wide which can be treated in 4 to 5 weeks or when vegetation in treated lanes has decqmposed. During the growing season, decomposition of treated strips will usually occur in 2 to 3 weeks. Page 26 of 28
