GENERAL INFORMATION Apply CONTOUR herbicide only on selected field com hybrids (IMI-Com) warranted by the seed company to possess resistance/tolerance to direct applications of imazethapyr (pURSUIT®) herbicide. DO NOT apply CONTOUR to corn hybrids which lack resistance/(.)lerance to imazethapyr (pURSUIT) herbicide. Contact your seed supplier, chemical dealer ur American Cyanamid to obtain information regarding IMI-Corn hybrids. CONTOUR can be applied early preplant, preplant incorporated, preemergence, or postemergence on IMI­ Corn hybrids. The application method of choice will depend on the anticipated weed spectrum and the preference of the applicator. CONTOUR herbicide kills weeds by root ancVor foliage uptake and rapid translocation to tlle growing points. Adequate soil moisture is important for optimum CONTOUR activity. When adequate soil moisture is present, CONTOUR will provide residual control of susceptible germinating weeds; activity on established weeds will depend on the weed species and the location of its root system in the soil. Usc of CONTOUR herbicide in accordance with label directions is expected to result in nonnal growth of rotational crops; however, various environmental and agronomic factors make it impossible to eliminate all risks associated with the usc of this product and, therefore. rotational crop injury is always possible. Under sOllle conditions (such as heavy texture soil, high organic matter, low pH or low rainfall) CONTOUR lIlay cause injury to subsequent planted crops. Sec the ROTATIONAL CROP GUIDELINE section of this label for recommended rotation intervals to sensitive crops. Crops growing under stressful environmental conditions can exhibit various injury symptoms which may be more pronounced if herbicides are used. Com plants treated with CONTOUR may exhibit yellowing on new growth. Such effects occur infrequently and are temporary. Nornlal growth and appearance should resume within I to 2 weeks. Naturally occuning bio'ypcs' of some of the weeds listed on this lahel may not be effectively ('<)ntwllell by this an(Vor other products with either tile ALSI AHAS enzyme inhibiting mode of action or the photosynthesis inhibiting m(xle of action. Otiler herbicides with tlle AL"I AliAS enzyme inhibiting mode of action include the sulfonylureas (r g. AccentT", Basis™, ClassieT", Coneen T", ExceedT", Pennit T", Pinnacle T", etc.) tile sulf~lI1amides (e.g. Broadstrike T", etc.) and tlle pyrimidyl benzoate (e.g. StapleT", etc.), Herbicides witll tlle photosyntllesis inhibiting mode of action inclUde the tIia;1jne herbicides (e.g, atrazine, BJadexTM, Extrazine™, Sencor™, etc.). If naturally occuning biotypcs are present in a field which are resistant to one of tlle herbicides in this premix and arc not controlled by tl1c other mode of action herbicide in tllis premix, CONTOUR should be tank-mixed or applied sequentially witll an appropriate registered herbicide having a different mode of action to ~nsure control. * A weed biotype is a naturaIly occuning individual witllin a given species Jmt has a &lightiy differ.:nt, but distinct genetic makeup from other plants. 1>1 ') , ) Replanting: If replanting is necessary in a field previously treated with CONTOUR, the field may be replanted to U.lI-Com. Rework the soil no deeper than thl' treated zone. DO NOT apply a second treatment of CONTOUR. MIXING INSTRUCTIONS POSTEMERGENCE APPLICATIONS OF CONTOUR HERBICIDE REQUIRE ADDITION OF AN ADJUV ANT AND A LIQUID FERTILIZER· SOLUTION. I. ADJUVANTS SURFACTANTS: Use a nonionic sw-factant containing at least 80% active ingredient. Apply the surfactant at the rate of I quart per 100 gallons of spray solution. OR CROP OIL CONCENTRATE: Instead of a surfactant, a petroleum or vegetable seed oil based crop oil concentrate (such as SUN-IT nTM) may he used. SUN-IT n is recommended when wee(i~ arc under moisture or temperature stress. Use SUN-IT II, or otller methylated seed oils, at tlle .ate of 1.5 to 2 pints per acre (use tlle higher rate when weeds are at tlle maximum label size), or usc a crop oil concentrate at 2 pints per acre. AND II. LIQUID FERTILIZER SOLUTION Recommended nitrogen hased fenilizers include liqUid fertilizers (such as 28%N, 32%N or 10-34-(1) at the rate of 1-2 quarts per acre. Usc the higher rate whcn weeds arc under moisture or temperature stfess. Instead of a liquid fertilizer, spray grade ammonium sulfate may be used at tile rate of 7. ; f'<1I1 mls per acre. Nute: In case of a compatihility prohlem when mixing crop oil concentrate or methylated seed oil with this pr(xluct and water, usc of a phosphate-contail1lng compatihility agent is reCOl1lll1Cllllct1. • ('( lNT( lUR applications lIlay he made with a nOll-Ionic surfactant only (liquid fertilizer not required) in t'le states of Arkansas, Boothecl of Missouri, Tennessee.

Compatibility Testing T(, ensure compal1bility of CONTOUR in liquid fertilizer (soil applications only) or in tankmixes with "ther herbicides and water, a jar compatibility test is recommended, Check compatibility using the following procedure: I, Add I pint of carrier (lil]uid fertilizer or w'Hcr) to each of 2, one quart. jars with tight lids. 2. To one of thc jars add 114 teaspoon of a phosphate-containing compatibility agcnt, Agitate thc solution. J To [)otl! jars, add the appropriate amount of herbicide(s) in the following ordcr: dry formulations (WI', DC;. DF, LF, SG (soluble granule), CONTOUR, aqueous solutions, and EC's, Approximate Herbicide Use Rates: Dry Formulations: Add 1/4 teaspoon for every 2.5 ounces of product used per acre. Liquid Formulations: Add 112 teaspoon for every pint of product used per acre. 4. Alter adding all ingredients to each jar, attach lids and invert jars IO times to mix. Allow the mixture to stand for 15 minutes then IlXlk for signs of incompatibility such as separation or preCipitate fomlation (flakes, crystals, films, etc.). Determine if the compatibility agent prevents incompatibility and usc accordingly. To avoid injury to sensitive crops, s~ray equipn:cnt used for CONTOUR applications must he drained and thoroughly cleaned with water heron~ .1ei!'~ used to apply other products. See the "Environmental Hazards" section of this label for precautions r< ,: Icerni ng products containing atrazine, When CONTOUR is used in combination with another herbicide, refer to the respective lahel for rates, methods of application, proper liming, weclts contwlled, restrictions amI precautions, Always use in aCCl1nlance with the more restrictive lahel restrictions and precautions, No lahel dosages should be exceeded, CONTOUR herbicide cannot he mixed with any product containing a label prohibiting such mixtures, SPRAYING INSTRUCTIONS (iROUNI> APPLICATI()NS: Unililflllly apply with pf()p,~rJy calibrated gmund c4uipIlI,~nt in 10 or more gallons of water per acre. A spray pressure of 20 to 40 psi is rl~conHIlCnde(i. To ensure tilorough cOVl'ragc, use a minimum of 20 gallons of water per acre when applying CONTOUR to minimum or no-till IMI-Corn. Use higher gallonage for llelds with dense vegetation or heavy crop residues. Adjust the boom height to ensure proper coverage of weed foliage (according to the manufacturer's recommclIllation). Use only flat-fan nozzles for post emergence applications. -\ void overlaps when spraying. DO NOT apply with ground equipment when wind velocity is greater than 10 mph, or when SpITty may be carried to sensitive crops. Sensitive crops include leafy vegetables, sugarbeets, red table beets and cotton. AERIAL APPLICATIONS: Uniformly apply witl! properly calibrated aerial equipment in 5 or more gallons of viater per acre. When applied POSTEMERGENCE, tile addition of a non-ionic surfactant AND fertilizer solution are required for optimum weed control; apply a non-ionic surfactant at the rate of 1 quart per 100 gallons of spray mixture OR ins(.;ad of a non-ionic surfactant, add a petroleum or vegetable based seed oil (such as SUN-IT JFM) at the rate of 1.25 gallons per 100 gailolL~ of spray mixture AND a liquid fertitizer at the rate of I qUaIl per acre. To avoid injury to sensitive crops from drift, aerial appli"'1tors n:ust adhere to (toe following SPECIAL AERIAL USE DIRECfIONS AND PRECAUTIONS.

Coarse sprays (larger droplets) arc less likely to elrin. Avoid applications to humans or animals. Flagmen and loaders should avoid inhalation of spray mist an,1 prolonged contact with skin. Applicator is responsihle for any loss or damage which results from spraying CONTOUR in a manner other than recollllllended in this label. In addition, applicator must follow all applicable state and local regulatiolls and ordinances in regards to spraying. DO NOT apply this product through any type of irrigation system. 9/% !I~;!' USE RATE (I-W PINTS PEI{ ACRE) Apply CONTOUR at a hroadcast rate of 1-1/3 pints per acre for all methods of application: early preplant, preplant incorporated, prccmergence (including minimum and no-till), aJl(1 postcmcrgcnce. At this broadcast rate, one gallon of CONTOUR will treat 6 acres of IMI-Corn. This is equivalent to 0.063 Ihs. imal.ethapyr and U.S Ibs. atral.inc active ingrcdient per acrc. NOTE: Only one application of CONTOUR herhicide may be made during the growing season. Where there are statellocal requirements regarding atrazine use (including lower maximum rates and/or higher set-hacks) which are different from the label, the more restrictive/protective requirements apply. CONTOUR HERBICIDE USE AREA (Not for \L~e in California or New York) DO NOT apply CONTOUR to IMI-Corn in North Dakota and in Minnesota north of state highway 210. APPLlCA TION INSTRUCTIONS POSTEMERGENCE CONTOUR is effective in controlling weeds in conservation tillage as well as i conventic,:tl production systems. Apply CONTOUR herbicide a~ a poslemergencc treatment to IMI-Com when crop and weed~ arc actively growing. Apply CONTOUR before weed~ exceed a height of 3 inches, unless otherwise indicated and before corn rcaches 12 inches in height. Delay application until the majority of the wee(i~ are at the recomm~ndcd growth stage. More restrictive crop growth stage limitations of t~nk-mix partners must he i()llowct1. An adjuvant (either a surfactant or a crop oil concentrate) amI a liquid fertilizer must be added to the spray solution for optimum weed control activity. Sec the A:)D1TIVE section uncler MIXIN() INSTRUCTIONS for specific instructions. For maximum weed control, cultivate 7-]() days r"llowing a postemergence CONTOUR application. '1l1is timely cultivation will enhance residual weed c(,ntrol, especially under dry conditions. If air temperatures reach or stay below 40°F for 10 or more hours, delay a CONTOUR application for 48 hours from the time temperatures increase abo oe 40°F. Unusually cool temperatures (40°F or less) reduce photosynthesis and transpiration and thus reduce the uptake and translocation (and effcctiveness) of CONTOUR in wceds. CONTOUj{ herhicide should be applied a minimum of one hour before rainfall or overhea(\ irrigation. SOIL APPLICATIONS CONTOUR can he applied as an early preplant, preplant incorporated, or precmcrgence treatment in IMI­ Corn. CONTOUR provides effective weed control in conservation tillage systems designcd to me('t cOl1s'~rvation C()[Jlpliancc requircments. It can also be applied in convcOltional. minimum tillage and IHHili pnx\uction systems. 111C application TIIeill0d of choice will depend on the anticipatecl weed spectnllil and the preference of the applicator. 10 SOIL AJ>I'LiCATIONS WITH LlQUI[) FERTILIZERS C< lNTOUR can he applied to the soil in liljuid fertilizers, alone or in combillalion wilh PROWL@ 3.3 EC herhicide (preemergence only, DO NOT incorporate PROWL), Eradicanc i~xtra''', Sutan+'fM,Lasso EC'" , Lasso MTfM , Harness PlusH', Surpass ' '', or DuaF". follow all CONTOUR herbicide label recommendations regarding incorporation, timing of application, special instructions and precautions.

(Sec Mixing Instructions for compatibility testing guidelines). PREPLANT INCORPORATED APPLICATIONS CONTOUR may be applied following land preparation and should be thoroughly Incorporated to a depth of I tll 2 inches. Application may be made up to 45 days prior to planting. Mechanical incorporation can be achieved by one of the following: (a) Disk harrow set to Cllt 3 to 4 inches deep and operated at 4 to 6 mph with the second pass at an angle to the first. (b) VJ'O-driven equipment (tillers, cultivators, hoes) set to cut 2 to 3 inches deep and operated one time at 4 mph or less. (c) Rolling cultivator set to cut 'J, to 4 inches deep and operated two times at 6 to 8 mph with the second pass at an angle to the first. Use only on coarse textured SOils. «(I) Held cultivator with :I or 4 rows of sweeps (Do not use chisel points), spaced at intervals of 7 inches or less and staggered so that no soil is left untumcd, set to cut 3 inches deep, and ope.rated two tiIlles at more than 5 mph with the seccln(i pass at an angle to the Ilrst.

If corn is planterl on beds, apply and incorporate after bed formation using l'TO-driven equipment or a rolling cultivator. PREEMERGENCE (SURFACE APPLICATIONS) CONTOUR offers IlcxitJility in that it can be utilized in all production tillage systems. It can be applied prior to planting or at planting in conventional, reduced tillage or no-till pffxiuction systems. Adequate soil moisture is required for optimum activity. I'm surface applications, rainfall or overhead irrigatiolJ is necessary tn move CONTOUR into the weed germination zone. The amount of rainfall or in'igation required 1()lIowing applicatIOn depends on existing soil IIIoisture, soil texture aTHI organic matter content. Sufficient water to llIoisten the soil to a depth PI' 2 inches is normally adequate. If adequate moisture is not .cccivcd within 7 (lays after a surface-applied treatment. then a cultivation is recommended to control cscap\~d weeds. 11 9/9G When adeljuate lIloisture is rcccived after dry conditions, CONTOUR will provide residual control of susccptlhlc germinating weeds; activity on cstahlished weeds will depend on the weed species d Leaf Stage (inches) . -. _ .. _'---_._-------_. ----_ ... - -----. _.- Mustard sp.
