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. For any re­ quirements specifc to your State or Tribe, consult the agency responsible for pesticide regulation. AGRICULTURAL USE REQUIREMENS Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR part 170. This Standard contains requirements for the protection of agricultur~l work­ ers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification, and emergency assis­ tance. It also contains specific instructions and exceptiops pertaining to the statements on this label about personal pro­ tective equipmel1t (PPE) and restricted-entry interval. The re­ quirements 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 L,try interval (REI) of 12 hours. Exception: If the product is soil-injected or sOil-incorporated, the Worker Protection Standard, under certain circumstances, allows workers to enter the treated area if there will be no contact with anything that has been treated.

-4- NON-AGRICULTURAL USE REQUIREMENTS The requirements in this box aFply to uses of this product that are NOT within the scope of the Worker Protection Standard 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. Do not enter treated areas without protective clothing until sprays have dried. FAILURE TO FOI,LOW THE DIRECTIONS FOR USE AND PRECAUTIONS ON THIS LABEL MAY RESULT IN POOR WEED CONTROL, CROP INJURY, OR ILLEGAL RESIDUES. Do not apply this product through any type of irrigation system. " i ,

-5- General Information This herbicide controls many annual broadleaf and grass weeds in corn, sorghum, sugarcane, and certain other crops specified on this label. This product may be applied before or after weeds emerge. Following many years of continuous use of this product and chemically related products, biotypes of some of the weeds listed on this label have been reported which cannot be effec­ tively controlled by this and related herbicides. Where this is known or suspected and weeds controlled by this product are expected to be present along with resistant biotypes, we recom­ mend the use of this product in combinations or in sequence with other registered herbicides which are not triazines. If only resistant biotypes are expected to be present, use a registered non-triazine herbicide. Consult with your state Agricultural Extension Service for specific recommendations. Since this product acts mainly through root absorption, its effectiveness depends on moisture to move it into the root zone. If weeds develop, a shallow cultivation or rotary hoeing will gene~ally result in better weed control. This product is noncorrosive to equipment and metal surfaces, nonflammable, and has low electrical conductivity. Avoid using near adjacent desirable plants or in greenhouses, or injury may occur. To avoid spray drift, do not apply under windy conditions. Avoid spray overlap, as crop injury may result. Where the use directions give a range of rates, use the lower rate on coarse-textured soil and soil low in organic matter; use the higher rate on fine-textured soil and soil high in organic matter. Note: Ciba-Geigy does not recommend applications in combination with other herbicides or oils, except as specifically described on the label or in literature published by Ciba-Geigy. APplication Procedures Ground application: Use conventional ground sprayers equipped with nozzles that provide accurate and uniform application. Be certain that nozzles are uniformly spaced and are the same size. Calibrate sprayer before use and recalibrate at the start of each season and when changing carriers. Unless otherwise speci­ fied, use a minimum of 10 gals. of spray mixture/A for all pre­ plant incorporated, preplant surface, preemergence, and post- .. ,

-6- emergence applications (with or without oil or surfactant) with ground equipment. Use a pump with capacity to (1) maintain 35-40 psi at nozzles, (2) provide sufficient agitation in tank to keep mixture in sus­ pension, and (3) to provide a minimum of 20% bypass at all times. Use centrifugal pumps which provide propeller shear action for dispersing and mixing this product. The pump should provide a minimum of 10 gals./minute/IOO gal. tank size circu­ lated through a correctly positioned sparger tube or jets. Use screens to protect the pump and to prevent nozzles from clogging. Screens placed on the suction side of the pump should be 16-mesh or coarser. Do not place a screen in the recircula­ tion line. Use 50-mesh or coarser screens between the pump and boom, and where required, at the nozzles. Check nozzle manufac­ turer's recommendations. For band applications, calculate amount to be applied per acre as follows: band width in inches row width in inches x broadcast rate per acre amount needed per acre of field Aerial application: Use aerial application only where broadcast applications are specified. Apply in a minimum of 1 gal of water for each 1 lb of this product applied per acre. For poS1_­ emergence treatments on corn and sorghum, apply recommended rate in a minimum of 2 gals. of water/A. Avoid applications under conditions where uniform coverage cannot be obtained or where excessive spray drift may occur. Avoid application to humans or animals. Flagmen and loaders should avoid inhalation of spray mist and prolonged contact with skin. Application in water or liquid fertilizer: Nitrogen solution or complete liquid fertilizer may replace all or part of the water as a carrier for preemergence, preplant incorporated, or pre­ plant surface ground application on corn and sorghum. Check the compatibility of this product with liquid fertilizer and/or nitrogen solution as shown below before use. Do not apply in nitrogen solution or complete liquid fertilizer after corn or sorghum emerges. ..,

-7- ~ompatibility Test: Since liquid fertilizers can vary, even within the same analysis, always check compatibility with herbi­ cide(s) each time before use. Be especially careful when using complete suspension or fluid fertilizers as serious compatibil­ ity problems are more likely to occur. Commercial application equipment may improve compatibility in some instances. The fol­ lowing test assumes a spray volume of 25 gals. per acre. For other spray volumes, make appropriate changes in the ingredi­ ents. Check compatibility using this procedure:

1. Add 1 pint of fertilizer to each of 2 one-quart jars wi th tight lids.
2. To ~ of the jars add 1/4 tsp. or 1.2 milliliters of a compatibility agent approved for this use, such as Compex® or Unite® (1/4 tsp. is equivalent to 2 pts. per 100 gals. spray). Shake or stir gently to mix.
3. To both jars add the appropriate amount of herbi­ cide(s). If more than one herbicide is used, add them separately with dry herbicides first, flowables next, and emulsifiable concentrates last. After each addition, shake or stir gently to thoroughly mix. The appropriate amount of herbicides for this test follows: Dry herbicides: For each pound to be applied per acre, add 1.5 level teaspoons to each jar. Liquid herbicides: For each pint to be applied per acre, add 0.5 teaspoon or 2.5 milliliters to each jar.
4. After adding all ingredients, put lids on and tighten, and invert each jar ten times to mix. Let the mixtures stand 15 minutes and then look for sepa­ ration, large flakes, precipitates, gels, heavy oily film on the jar, or other signs of incompatibility. Determine if the compatibility agent is needed in the spray mixture by comparing the two jars. If either mixture separates, but can be remixed readily, the mixture can be sprayed as long as good agitation is used. If the mixtures are incompatible, test the following methods of improving compatibility: (A) slurry the dry herbicides(s) in water before addition, or (B) add 1/2 of the compatibility agent to the fertilizer and the other 1/2 to the emulsifi­ able concentrate or flowable herbicide before addi­ tion to the mixture. If incompatibility is still ob­ served, do not use the mixture . .. ' I.......- _______________________ ~.--------

-8- Application in water plus emulsifiable oil or oil concentrate: Adding emulsifiable oil (petroleum-derived, petroleum-derived oil concentrate, or single or mixed crop-derived oil concen­ trate) to postemergence water-based sprays in corn and sorghum may improve weed ~ontrol. However, under certain conditions the use of either type of oil may seriously injure the crop. To minimize this possibility, observe the following directions: Use one of the following properly emulsified:

1. A suitable oil concentrate containing at least 1\ but not more than 20% suitable emulsifier or surfactant blend.
2. Petroleum-derived oil containing at least 1% suitable emulsifier. Note: In the event of a compatibility problem when mixing oil with this product and water, a compatibility agent such as Compex or Unite should be used. Any of the above oils contaminated with water or other materials can cause com­ patibility problems and/or crop injury. Mixing procedures - all uses: (1) Be sure sprayer is clean and not contaminated with any other materials, or crop injury or sprayer clogging may result. (2) Fill tank 1/4 full with clean water, nitrogen solution, or complete liquid fertilizer. (3) Start agitation. (4) Be certain that the agitation system is working properly and creates a rippling or rolling action on the liquid surface. (5) Pour product directly from bag into tank. (6) Continue filling tank until 90% full. Increase ag­ itation if necessary to maintain surface action. (7) Add emulsifiable oil, oil concentrate, or tank mix herbicide(s) after this product is thoroughly suspended. (8) Finish filling tank. (9) Empty tank as completely as possible before refilling to prevent buildup of oil or emulsifiable concentrate residue. Maintain agitation to avoid separation of materials. (10) If an oil or emulsifiable cncentrate film starts to build up in tank, drain it and clean with strong detergent solution or solvent. (11) Clean sprayer thoroughly immediately after use by flushing system with water containing a detergent. Rotational CrQPs - All Uses: (1) Do not rotate to any crop except corn or sorghum until the following year, or injury may occur. (2) If applied after June lu, do not rotate with crops other than corn or sorghum the next year, or crop injury may occur. (3) In the High Plains and Intermountain areas of the West where rainfall is sparse and erratic or where irrigation is required, use only when corn or sorghum is to follow corn or sorghum or when a crop of untreated corn or sorghum is to pre­ cede other rotational crops. (4) In eastern parts of the Dakotas, KS, westrn MN and NE, do not rotate to soybeans if the

-9- rate applied to corn or sorghum was more than 2.5 lbs./A or equivalent band application rate, or soybean injury may occur. (5) Injury may occur to soybeans planted the year following application on soils having a calcareous surface layer. (6) Do not plant sugar beets, tobacco, vegetables (including dry beans), spring-seeded small grains, or small-seeded legumes and grasses the year following application, or injury may occur.
