PLATEAU DG may be used for the release of unimproved berrnudagrass, bahiagrass, centipede, smooth bromegrass, wheatgrass, "wildtype" common Kentucky bluegrass, native prairiegrass, wildflowers, crown vetch and certain legumes. PLi-TEAU DG can also be used for weed control during the establishment of native prairie grasses (see NATIVE PRAIRIEGRASS RENOVATION AND RESTORATION). PLATEAU DG is readily absorbed through leaves, stems, and roots and is translocated rapidly throughout the plant, with accumulation in the meristematic regions. Treated plants stop growing soon after spray application. Chlorosis appears first in the newest leaves, and necrosis spreads from this point. In perennials, the herbicide is translocated into, and kills, underground storage organs which prevents regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species for several weeks after application. Complete kill of plants may not occur for several weeks after application. Adequate soil moisture is important for optimum PLATEAU DG activity. When adequate soil moisture is present, PLATEAU DO will provide residual control of susceptible germinating weeds. Activity on established weeds will depend on the weed species and rooting depth. ) PLATEAU DG is rainfast one hour after application. 4 2/00 (

PLATEAU DG will control annual and perennial grasses and broad leaf weeds and vine species. PLATEAU DG will provide residual control of labeled weeds which germinate in the treated area. Certain brush species and ornamentals may be injured by direct application of PLATEAU DG to their foliage. This product may be applied ) either preemergence or postemergence to the weeds. However, post emergence application is the method of choice in most situations, particularly for perennial species. For maximum activity, weeds should be growing vigorously at the time of postemergence applications and the spray solution should include an adjuvant (See "Adjuvants" Section). These solutions may be applied as a broadcast or as a spot treatment using backpack, or ground equipment. I , PLATEAU DG may be applied in the dormant or growing season for weed control. Depending on the turf type being treated, some yellowing of turf may occur with applications during the growing season. Depending on weather conditions, yellowing will usually eiisaj3j3ear appear in 2 to 4 weeks. PLATEAU DG should not be applied to newly seeded or sprigged grass stands, unless otherwise stated in this label. See COASTAL BERMUDAGRASS and PRAIRIEGRASS RENOVATION AND RESTORATION sections. MIXING INSTRUCTIONS Fill the spray tank one-half to three-quarters full with clean water. Add required number of PLATEAU DG water soluble packets to spray tank while agitating. Fill the remainder of the tank with water. For postemergence applications, add a surfactant to the spray tank (See Adjuvants section of this label for specific recommendations). Maintain agitation while spraying to ensure a uniform spray mixture. An antifoaming agent may be added to the tank if needed. ) When tank-mixing PLATEAU DG with recommended herbicides, add PLATEAU DG to the spray tank first and make sure it is thoroughly mixed before adding the other herbicides. PLATEAU DG is a pre_measured quantity (1.44 oz) of water dispersible granules, contained within a water soluble packet. The water soluble packets must be used as a whole unit. DO NOT open and subdivide packets when preparing a spray mixture. For use rate recommendations that prescribe partial water soluble packet per ( . ') acre rates, refer to the table below for the equivalent whole packet per acre rate. ) Partial Water Soluble Packet per Acre Rate Equivalent Whole Water Soluble Packet Rate 0.5 per acre 1.0 per 2 acres 0.75 per acre 1.0 per 1.3 acres 1.5 per acre 1.0 per 0.6 acres 2.5 per acre 1.0 per 0.4 acres SPRAYING INSTRUCTIONS DO NOT apply during windy or gusty conditions unless applications are being made with an enclosed or shielded spray system. DO NOT apply if rainfall is threatening. Rainfall within I hour after PLATEAU DG application may reduce postemergence weed control. 5 2/00

GROUND APPLICATIONS: Unifonnly apply with properly calibrated ground equipment in 2 or more gallons of water per acre. Application ) equipment. specially designed to make low volume application should be used when making applications using less than 10 gallons of water per acre. A spray pressure of 20 to 40 psi is recommended. Adjust the boom height to ensure proper coverage of weed foliage or soil surface (according to the manufacturer's recommendation). Avoid overlaps when spraying. SPOT TREATMENTS: mixture as follows: For water soluble ackets of RAY ADJUVANTS FOR acket er acre and use 2 to 3 water soluble ackets er acre for eren .

For small hand held sprayers. prepare a stock mixture by thoroughlv dissolving I water soluble packet of PLA TEAU DG herbicide per gallon of water and thoroughly mix. Make sure that the mixing container is opaque to sunlight or UV treated. PLATEAU DO herbicide breaks down rapidlv when mixed in water and exposed to sunlight. Stock mixtures of PLATEAU DG herbicide in water should be used within two days of being prepared to prevent deterioration of the herbicide mixture. Mix thoroughly before removing additional stock mixture. See the following table to detennine the amount of stock mixture to add to make one gallon of spray mixture. ) One gallon of sprav mixture will cover 1000 square feet. ) Equivalent PLATEAU DG Amount of stock solution to be added to one gallon of spray mixture. herbicide rate per acre (water soluble packets} Fluid ounces Milliliters Cups I 2.9 87 0.37 2 5.9 174 0.73 3 8.8 261 I.l Use of a methylated seed oil is recommended when targeting noxious weeds.

AERIAL APPLICATION: All precautions should be taken to minimize or eliminate spray drift. Fixed wing aircraft and helicopters can be used to apply PLATEAU DG, however, when making applications by Ilxed wing aircraft maintain appropriate ) buffer zones to prevent spray drift out of the target area. Aerial equipment designed to minimize spray drift such as a helicopter equipped with a MICROFOIL~ boom, or THRU-VALVE~ boom or raindrop nozzles, must be 6 2/00 /

~) used and calibrated. Except when applying with a MICROFOIL boom, a drift control agent may be added at the recommended label rate. To avoid drift, applications should not be made during inversion conditions, when winds are gusty, or under any other conditions which promote spray drift. Uniformly apply recommended amount of PLATEAU DG in 5 or more gallons of water per acre, using enough volume to provide adequate coverage of target area or foliage. Include an adjuvant in the spray solution (See "Adjuvants" Section). A foam reducing agent may be added at the recommended rate, if needed. IMPORTANT: Thoroughly clean application equipment, including landing gear, immediately after use of this product. Prolonged exposure of this product to uncoated steel (except stainless steel) surfaces may result in corrosion and failure of the exposed part. The maintenance of an organic coating (paint) may prevent corrosion. Avoid overlaps when spraying. SPRA Y ADJUVANTS FOR POSTEMERGENCE APPLICATIONS Postemergence applications of PLATEAU DG require a spray adjuvant. See "Special Weed Control" section. Due to variations in surfactant contents, certain surfactants containing high amounts of alcohols, paraffin based petroleum oils, and other compounds which can increase phytotoxicity to desirable vegetation, it is recommended to choose a low phytotoxic surfactant. Methylated Seed Oils or Vegetable Oil Concentrates: Instead of a surfactant, a methylated vegetable-based seed oil concentrate containing 5 to 20% surfactant and tRe FemaieEleF eftRe 80 to 95% methylated vegetable oil may be used at the rate of 1.5 to 2 pints per acre. Methylated seed oils provide their greatest effects at 30 GPA or less. At spray volumes above 50 GPA, their advantage appears negated. When using spray volumes greater than .J' 30 gallons per acre methylated seed oil or vegetable based seed oil concentrates should be mixed at a rate of 1% of the total spray volume or alternatively use a nonionic surfactant as described below. Research indicates these oils may aid in deposition and uptake of PLATEAU DG for hard-to-control perennials, waxy leaf species or when plants are under moisture or temperature stress. DO NOT use a methylated seed oil or vegetable oil concentrate when making applications to newly emerged seedling prairiegrasses or wildflowers as injury may ') Non ionic Surfactants: Use a nonionic surfactant at the rate of 0.25% v/v or higher (see manufacturer's label) of the spray solution (0.25% v/v is equivalent to 1 quart in 100 gallons). For best results, select a non ionic surfactant with a HLB (hydrophilic to lipophilic balance) ratio between 12 and 17 and having at least 60% surfactant in the formulated product (alcohols, fatty acids, oils, ethylene glycol or diethylene glycol should not be considered as surfactants to meet the above requirements). Silicone-Based Surfactants: See manufacturer's label for specific rate recommendations. Silicone-based surfactants may reduce the surface tension of the spray droplet allowing greater spreading on the leaf surface as compared to conventional non ionic surfactants. However, some silicone-based surfactants may dry too quickly, limiting herbicide uptake and higher spray volumes may exhibit "run-off'. Fertilizer/Surfactant Blends: Nitrogen-based liquid fertilizers such as 28%N, 32%N, 10-34-0, or ammonium sulfate, may be added at the rate of 2 to 3 pints per acre in combination with the recommended rate of non ionic surfactant or methylated seed oil. Research indicates that nitrogen based fertilizers aid in the burndown of annual weeds and increase PLATEAU DG uptake through waxy leaf species. However, fertilizers may increase phytotoxicity to desired species and newly emerged seedling prairiegrasses and wildflowers. The use of ) fertilizers in a tank-mix without a nonionic surfactant or a methylated seed oil is not recommended and may _ result in herbicide failure. 7 2/00

TANK MIXES PLA TEA-U DG herbicide may be tank-mixed with PENDULUM@ herbicide for additional control of late season ) annual grasses and certain broadleaves. For additional weed control, PLATEAU herbicide may be tank-mixed with A;.8,,1+, R£J\lIIoffijlPre+, glYflR8sate, ARSBl>IAb@ Remi.ide, Di!Fasri, Camflsige+, FiBsle"-, GsrleB 3A~, MSMA VaB~uisR4, OustP-, "seartP-, ACCORDTM.

A compatibility test is advised for products not listed. 2,4-0 and other phenoxy type herbicides have resulted in reduced control of perennial grass weeds. DO NOT tank mix with organophosphate insecticides or use organophosphate insecticides the same year as PLATEAU DG herbicide on newly seeded areas. Consult manufacturer's labels for specific rates and weeds controlled. Always follow the more restrictive label when making an application involving tank-mixes. FOR FOLIAR AND SEEDHEAD SUPPRESSION OF BAHIAGRASS, COOL SEASON GRASSES AND SUPPRESSION OF SOME ANNUAL WEEDS ) Bahiagrass: PLATEAU DG may be used at the rate of 0.5 + water soluble packets per 8Be half te w.'e acre to suppress growth and seedhead development of bahiagrass in unimproved areas. In North and South Carolina it is recommended to use PLATEAU DG at the rate of Q) + water soluble packet per !We acre, as higher rates may cause rurf thinning. Depending on rate of PLATEAU DG used, surfactant and environmental conditions, temporary turf discoloration may occur. For optimum performance, application should be made after green-up. Applications may be made before or after mowing. If applied prior to mowing, raise mowing height to leave adequate existing foliage as new growth will be suppressed. If applied after mowing, allow adequate foliage to ') remain by increasing mower height or allowing time for foliar regrowth prior to application. DO NOT apply to turf under stress (drought, cold, insect, disease, etc.) or severe injury may occur. DO NOT use a methylated seed oil adjuvant. Gse Water Soluble Packets per Acre ;;!-aeres 0.5 .J--oore 0.75-1.5 Phytotoxicity none to low low to moderate Length of Suppression partial to season long season long "j For winter annual weed control, apply 2 water soluble packets of PLATEAU DG per acre when bahiagrass is dormant, but when weeds are actively growing. This can be followed by I water soluble packet of PLATEAU DG per acre in the spring after bahiagrass green-up for the suppression of seedheads and foliage. Cool Season Grasses: KY31 Tall Fescne and "Wildtype Common" Kentncky Blnegrass: Apply PLATEAU DG at 0.5 to I water soluble packet per acre 8Be te twa aeres for foliar and seedhead suppression of certain cool season grasses such as "KY31" tall fescue and "wildtype common" Kentucky bluegrass. Add a surfactant to the + 0.5 water soluble packet per;! acre rate of PLATEAU DG for optimum performance. The addition of a surfactant to the I water soluble packet per acre rate of PLATEAU DG may cause excessive turf injury or mortality of tall fescue, Application to turf type tall fescue or Kentucky bluegrass may result in severe injury or loss of stand. Crested Wheatgrass: Apply PLATEAU DG at +-Ie--;! 1.5 to 2.5 water soluble packets per acre for foliar and ) seedhead suppression of crested wheatgrass. Other wheatgrass species may also be suppressed, however, apply PLATEAU DG to a limited area to determine effectiveness, Tank-mixes with 2,4-0 or products containing 2,4- 8 2/00

o mav decrease the effectiveness of PLATEAU DO. Tank-mixes with OARLON. TORDONTM. TRANSLINPM and VANOUISH GarlsR, TsrasR, TraRsliR8, aRa V!llllIisR may decrease the potential of turf injury. DO NOT "J apply to turf under stress or severe injury may occur. FOR THE CO:-lTROL OF UNDESIRABLE WEEDS IN UNIMPROVED BERMUDAGRASS PLATEAU DG may be used on unimproved bermudagrass turf such as roadsides, utility rights-of-way, railroad crossings, airports, non-irrigation drainage ditches and other such noncropland sites. There is a differential tolerance between berrnudagrass types (See below paragraphs). Depending on bermudagrass type, timing of application, and PLA TEA U DO rate, some foliar, stolon, and seedhead suppression may occur. IMPORTANT: Apply PLATEAU DO after berrnudagrass has reached full green-up. Spring applications made prior to full green-up may delay green-up. Always add a surfactant when applying PLATEAU DO. DO NOT apply to grass under srress from drought, disease, insects or other causes. Simultaneous mow/spray operations may suppress internode development. After mowing, allow adequate foliage regrowth prior to PLATEAU DO application as some internode suppression may prevent bermudagrass from quickly recovering from mowing. Common Bermudagrass: Common berrnudagrass is the most tolerant bermudagrass to PLATEAU DO. PL\ TE.\U DG at 1.5 to 3 water soluble packets per acre will provide control of labeled weeds as well as foliar and seed head suppression of established common bermudagrass. Tank-mixes with RSIIRall1' Prs, Asssra ROUNDUP PRO. ACCORD or glyphosate will improve the weed control spectrum, but may increase turf phlotoxicity. Some stolon internode shortening and seedhead suppression may occur for the first 8 weeks. Sprigged Coastal Bermudagrass: PLATEAU DO at I to 1.5 water soluble packet~ per acre may be applied at sprigging for weed control to aid in the establishment of coastal bermudagrass. DO NOT use on hybrid varieties such as Tifton 85. New World. etc . . ) Established Coastal Bermudagrass: PLATEAU DG at + .Li.to 3 water soluble packets per acre will provide , control of labeled weeds as well as foliar and seed head suppression of established coastal bermudagrass. Do not use on hvbrid varieties such as Tifton 85. New World, etc. Depending on environmental conditions and weed pressure, the longevity of suppression and weed conrrol increases as the PLATEAU DO rate increases. Tank­ mixes with RellRall1' Prs, A.ssra ROUNDUP PRO. ACCORD or glyphosate may result in death or excessive injury of coastal bermudagrass. Turf Type Bermudagrass: Turf type bermudagrass varieties show a high degree of variation in tolerance to PLA TEAU DG. PLATEAU DO at I to 1.5 water soluble packet per acre will provide some annual weed control and foliar & seedhead suppression. Rates above + 12 water soluble packet~ per acre may result in excessive injury or death of turf type berrnudagrass. SEE ABOVE SECTIONS FOR PLATEAU DG RATES AND TIMINGS FOR SPECIFIC BERMUDAGRASS TYPES WITH REGARD TO WEED CONTR .t"~ TURF TOLERANCE. Winter Annual Weed Control: Apply PLATEAU DO at the rate f~ 2.J.tO) 3 water soluble packets per acre prior to winter weed germination or while winter weeds are active growi . Early spring applications may delay green-up of berrnudagrass turf. Summer Annual Weeds: For best results, apply PLATEAU DO at the rate of 2 to 3 water soluble packets per acre pre-emergence or early postemergence before weeds have reached 6 inches in height. Larger weeds may be controlled depending on susceptibility, growing conditions, tank-mix partner and adjuvant selection. '" Perennial Weeds: Apply PLATEAU DO at the rate of2 to 3 water soluble packets per acre paste mergence after ) weeds have pwduced adequate foliage for herbicide uptake. For a particular weed' see "Special Weed Control" section below. The addition of Accord or Roundup Pro herbicide may increase control. 9 2/00

) Bahiagrass Control: Apply PLATEAU DG at the rate of:;?' 2.5 to 3 water soluble packets per acre postemergence. See SPECIAL WEED CONTROL section below for recommendations. The addition of RellRall1' Pre er ABBerG ROUNDUP PRO or ACCORD herbicide at 12 to 16 oz per acre may increase control. FOR THE CONTROL OF UNDESIRABLE WEEDS IN UNIMPROVED CENTIPEDE GRASS PLATEAU DG may be applied at a rate of I to 2 water soluble packets per acre' to established centipede grass for the control of annual broadleaf and grass weeds. Apply PLATEAU DG after centipede grass has reached full green-up. Spring applications made prior to full green-up may delay green-up. Always add a surfactant when applying PLATEAU DG. DO NOT apply to grass under stress from drought, disease, insects or other causes. Simultaneous mow/spray operations may suppress internode development. After mowing, allow adequate foliage regrowth prior to PLATEAU DG application as some internode suppression may prevent centipede grass from quickly recovering from mowing. FOR CONTROL OF UNDESIRABLE WEEDS IN SMOOTH BROMEGRASS, WILDTYPE COMMON KENTUCKY BLUEGRASS AND CRESTED WHEATGRASSES PLATEAU DG may be used on unimproved smooth bromegrass, "wildtype" common Kentucky bluegrass and crested, western. bluebunch and intermediate wheatgrass in non cropland areas. For other types of wheatgrass species, make application to small area to determine tolerance to PLATEAU DG. PLATEAU DG provides control of labeled grass and broadleaf weeds (See WEEDS CONTROLLED and SPECIAL WEED CONTROL sections). Treatment of smooth bromegrass and wheatgrass with PLATEAU DG may result in foliar height and seedhead suppression. Smooth Bromegrass and "Wildtype" Common Kentucky Bluegrass: Use PLATEAU DG at I to 2 water soluble packets per acre in the spring for weed control and growth suppression after smooth bromegrass and ') "wildtype" common Kentucky bluegrass have reached I 00% green-up. Applications prior to I 00% green-up ~ may delay green-up, Rates from 2 to 3 water soluble packets per acre may be applied in the spring but may result in excessive growth suppression, For fall applications (see SPECIAL WEED CONTROL section), PLATEAU DG may be used at 2 to 3 water soluble packets per acre for control of perennial weeds, Wbeatgrass: To control undesirable weeds in crested, western, bluebunch, intermediate and other wheatgrasses apply PLATEAU DG herbicide at I to 3 water soluble packets per acre. For wheat grass species other than crested. western. bluebunch and intermediate. make application to small area to determine tolerance to PLATEAU DG herbicide. FOR CONTROL OF UNDESIRABLE WEEDS IN CROWN VETCH PLATEAU DG may be applied at the rate of I water soluble packet per acre to newly seeded crown vetch beds to aid in the establishment of vetch and reduce weed competition. PLATEAU DG at 2 to 3 water soluble packets per acre may be used on unimproved established crown vetch in noncropland areas. PLATEAU DG provides control of labeled grass and broadleafweeds (Refer to the "Weeds Controlled" and "Special Weed Control" section for specific rates). Treatment of crown vetch beds with PLATEAU DG may cause internode shortening and some minor tip chlorosis depending on timing of application. PLATEAU DG should be applied during winter dormancy or early spring to reduce potential injury. Applications made after May, may result in increased injury or defoliation. Addition of surfactants such as .) dilimenene based or crop oil concentrates will increase injury. Fall applications during the period of active . crown vetch growth may result in severe injury or loss of stand. 10 2/00 "/.:;z

NATIVE PRAIRIE GRASS RENOVATION AND RESTORA nON PLATEAU DO may be applied at the rate of .j. 0.5 to 3 water soluble packets per acre to newly established or 1 existing stands of labeled species (see below for details) in such areas as roadsides, industrial sites, prairie restoration sites, drainage ditch banks, and other such noncropland areas. Certain local ecotypes or varieties may be suppressed by PLATEAU DO. Many factors such as poor seedling vigor, cool temperatures, poor soil, planting depth, excessive moisture, disease, insects and dry weather after emergence can all result in poor stands. Additional stress of herbicide residue, poor soils and other factors contributing to poor seedling vigor can also increase injury and could result in mortality. American Cyanamid can not be held responsible for such unforeseen factors. It is suggested to try PLATEAU DO on a small area iftolerance is not known. PLATEAU DO controls many annual and perennial grass and broadleaf weeds. Weed competition is reduced allowing prairiegrass seedlings to establish. PLATEAU DO is also effective for control of noxious weeds in established prairiegrass stands and must be applied postemergence as a foliar treatment to perennial weeds. IMPORTANT: ALWAYS ADD AN ADJUVANT when applying PLATEAU DO. To maximize weed control always use a methylated seed oil when treating established prairiegrass stands. Use a non ionic surfactant when treating newly emerged seedling prairiegrasses. The addition of liquid fertilizer will decrease grass tolerance and should not be used when treating newly emerged seedling prairiegrasses. PLATEAU DO may be applied at a rate of up to I water soluble packet per acre to Federal Conservation Reserve Program (CRP) land for the establishment or release of big bluestem, little bluestem, Indiangrass, sideoats and blue grama. Establishment: For optimum results in establishing mixed pramegrass stands with PLATEAU DG, make application at planting before prairiegrass seedlings emerge. Newlv emerged grasses can be sensitive to PLATEAU DO herbicide and/or the adjuvant used. If native warm season prairie grasses have begun to emerge, it is best to wait until thev have reached the five leaf stage to make a PLATEAU DO herbicide application and ) use a nonionic or silicone surfactant. Do not use a methylated seed oil at this time as some grass species tolerance will be lost. PLATEAU DG will control annual weeds preemergence or early postemergence. See "WEEDS CONTROLLED" section for maximum height of weeds and see below for more details on best rate and timing for prairiegrass and wildflower species. Postemergence applications may result in stand thinning due to variability in seedling grass tolerance to the use of spray adjuvants. Seedling grasses are generally more tolerant to the use of spray adjuvants after they have reach the five leaf stage. When planting into a field which was row cropped the previous year, compounded injury may occur from herbicide carry-over (See /' ) "DIRECTIONS FOR USE" section). Rates and Control: Apply PLATEAU DG at .j. 0.5 to 1.5 water soluble packet~ per acre to fields cropped the previous year, when annual weeds are the target and/or if grass/forb mixtures are used. PLATEAU DO at .j. 0.5 to 1.5 water soluble packet~ per acre will provide control and/or suppression of many annual grass and broadleaf weeds. Use lower rates when in the northern most U.S., dry climates or for late season plantings into clean seedbeds. PLATEAU DO herbicide rates as low as 0.5 water soluble packets per acre may be used on soils with a pH > 7. a low CEC and a course texture containing a minimum of clav and organic matter. Use higher rates in heavy weed pressure, heavy residue, high organic matter; high rainfall and long growing season (southern portions of Illinois, Indiana, Missouri and Ohio, etc.). Apply PLATEAU DO at 2 to 3 water soluble packets per acre for giant ragweed or for perennial weed control/suppression. PLATEAU DO rates of 2 to 3 water soluble packets per acre may result in stunting or stand thinning. The duration and intensity of suppression are directly related to weed pressure, chemical residue, soil type and environmental conditions. See below for details for particular grass tolerances and timings. Established Stands: For optimum results, apply PLATEAU DO as an early postemergence application to ') annual grasses and broad leaf weeds. For perennial weed control, see "SPECIAL WEED CONTROL" section. , The use of high rates may result in foliar and/or seed head height suppression of established stands of pramegrass. This effect is more likely to occur under conditions of light soils, low weed pressure, low rainfall, I I 2/00

. ) and short growing seasons. Use the lower rates for light weed infestations or when mixing with wildflowers and legumes (See "Wildflower" Section for rate tolerance). Use higher rates to broaden and lengthen weed control spectrum . Big Bluestem, Little Bluestem and Indiangrass: PLATEAU DG may be applied at the rate of .j. 0.5 to 3 water soluble packets per acre at planting, or any time thereafter, including after seedling grasses have emerged or to perennial stands (dormant or actively growing). See weed control section for desired rate. Use the lower rates in Wisconsin, Michigan, Minnesota, South Dakota, North Dakota, and Nebraska and higher rates as rainfall and/or growing season increases. Switchgrass (Panicum virgatum): PLATEAU DG is not recommended for the establishment of pure switchgrass stands as severe injury or death may result. PLATEAU DG may be applied at a rate of 0.5 to I water soluble packet per acre if switchgrass is planted in mixed stands with tolerant species, but only if some stand thinning or loss of stand can be tolerated. Mature switchgrass planting can be reclaimed from certain perennial weeds such as tall fescue, leafy spurge, johnsongrass, etc., with PLATEAU DG at rates of 22 to 3 water soluble packets per acre. However, severe stunting and injury is imminent. DO NOT apply PLATEAU DG to switchgrass if such severe injury can not be tolerated. Sideoats and Blue Grama: Apply PLATEAU DG herbicide to monoculture stands of sideoats and blue grama only if some stand thinning or loss of stand can be tolerated. PLATEAU DG may be applied at the rate of ~ 0.5 to I water soluble packets per acre plus an adjuvant to aid in the establishment of sideoats and blue gram a after new seedlings have emerged and reached the five (5) leaf stage. When using PLATEAU DG at ~ 1 water soluble packet per acre it is not recommended to use in combination with a methylated seed oil adjuvant as stand thinning may occur. The lower rates may provide adequate weed suppression in early summer plantings in the states of Wisconsin, Michigan, Minnesota, South Dakota, North Dakota, and Nebraska and other states where growing degree days are short. Sideoats and blue grama have shown tolerance to PLATEAU DG at 0.5 to I ) water soluble packet per acre, applied pre-emergence at planting, however, some stand thinning may occur. For weed control in established stands use I to 22 water soluble packets per acre of PLATEAU DG. Up to 3 water soluble packets per acre of PLATEAU DG may be applied, but may result in foliar andlor seed head suppression, ) or in the injury of sideoats and blue grama, depending on surfactant choice, soil type, variety, weed pressure and environmental conditions. Buffalograss: Apply PLATEAU DG at the rate of 0.5 to I water soluble packet per acre for control or suppression of labeled weeds and to aid in the establishment of newly sprigged buffalograss. Apply PLATEAU DG herbicide immediately after planting prior to spring growth or seed germination. New growth and small seedlings can be severely injured or killed. If applying after emergence it is best to wait until buffalo grass has at least five true leaves and use a non ionic or silicone surfactant. Do not use a methylated seed oil. For established stands, PLATEAU DG may be applied at the rate of .j. 0.5 to 2 water soluble packets per re for weed control. Higher rates may cause some turf discoloration and stunting. PLATEAU DG may be applied to dormant buffalograss to control winter annual weeds. Turf type buffalograss may express different tolerance level to PLATEAU DG than wild type buffalograss. Some turf types can tolerate low rates of PLATEAU DG at seeding. Consult seed dealer for details. Eastern Gamagrass: PLATEAU DG should only be used for the establishment or maintenance of eastern gamagrass if some stand thinning or loss can be tolerated. Apply PLATEAU DG at -I- 0.5 to 1.5 water soluble packet per acre at planting prior to gamagrass emergence. Stand thinning and stunting is imminent. Adverse conditions, poor soils, or added stress to the gamagrass could result in stand mortality. Postemergence application to seedlings will cause mortality. On established Eastern gamagrass, apply PLATEAU DG at -I- 0.5 to 2 water soluble packets per acre prior to gamagrass breaking dormancy. Some stunting will occur and increases as the PLATEAU DG rate increases. Applications made during or after green~up may result in foliar and ) seedhead suppression and possible mortality of weak plants. 12 2/00

Tall Fescue Control: Tall fescue can be controlled by using PLATEAU DG at the rate of 3 water soluble packets per acre plus methylated seed oil at 2 pints per acre in established stands of or to prepare a seed bed for big bluestem, little bluestem, and indiangrass. The addition of Nitrogen fertilizer (See "ADJUVANTS" Section) ') to the above mix will aid in control. Tall fescue must be actively growing for optimum control. If tall fescue has reached the boot stage or has reached summer dormancy, control may be poor. For improved control of tall fescue, PLATEAU DG may be tank mixed with ACCORD, ROUNDUP PRO Assenl, ReliRGlI1' PFe, or glyphosate. Fall applications of PLATEAU DG at 2 to 3 water soluble packets per acre, plus 24 to 64 ozl A ACCORD or ROUNDUP PRO Assenl eF ReliRGlI1' PFe will result in best control of existing tall fescue and new germinating seedlings. With spring applications of PLATEAU DG at 12 to 3 water soluble packets per acre, plus a ACCORD or ROUNDUP PRO ASSefG Sf ReliRGlI1' Pfe at 32 to 64 ozl A, use higher rates for older, mature fescue stands and lower PLATEAU DG rates when planting forbs. When using 2 water soluble packets per acre of PLATEAU DG in the fall with a glyphosate product, it is recommended to apply I water soluble packet per acre PLATEAU DG in the spring at planting for annual weed and seedling fescue control. Burning the fescue stand, where permitted, the following spring, just prior to green-up, will aid in control and provide a better' seedbed for planting. Mowing the fescue several times the summer before fall application, will weaken the fescue root system, making it more susceptible to herbicides. Always allow for at least 10 inches of regrowth, following the last mowing before spraying, as both PLATEAU DG and glyphosate products need foliage present for herbicide uptake and satisfactory control. ) ) PRAIRIE GRASS RENOV1I.TION , ....

Applv PLATEAU DG herbicide on Iv if some stand thinning or loss can be tolerated. Preemergence applications of low use rates (I water soluble packet per acre) to tolerant species, result in the least amount of injury, but may not eliminate it. Postemergence applications of PLATEAU DG can result in injury or death of some genotypes, and should be used only as a rescue treatment when weed competition threatens the stand. Use of certain spray adjuvants can also increase wildflower injury and loss of stand. Although most legumes listed in the tolerance table are tolerant to I water soluble packet per acre of PLATEAU DG preemergence, some stand thinning may occur. Legumes are more tolerant to post applications, but chlorosis or stunting is possible. Recommendations listed in the tables below are designed for mixed grasslwildflower stands. Less than satisfactory results may occur from applications to monoculture stands. It is recommended to try on a small scale to determine degree of satisfaction on monoculture stands . . ) For use in wildflower beds: Certain wildflowers have shown tolerance to PLATEAU DG applied pre­ emergence andlor postemergence. Apply PLATEAU DG at the rate of 0.5 to I water soluble packet per acre plus a silicone or non ionic surfactant to wildflower beds when weed competition threatens establishment or preser.ation of stand. Do not use a methylated seed oil or add fertilizer after seedling wildflowers have emerged or severe injury or death of some species may occur. Do not use if injury can not be tolerated. Species listed in the table below will outgrow early phytotoxicity. Higher rates may cause delayed flowering andlor height suppression of some species. Late postemergence applications (at bolting, bud or bloom set) on seedling and established beds will delay or prevent bloom. Combinations with PENDULUM® herbicide will provide broad 'J spectrum grass and broadleafweed control (see PENDULUM herbicide label for tolerant species). ) For prairiegrass/wildflower mixtures: Where some wildflower injury (phytotoxicity, height suppression) can ( be tolerated, apply PLATEAU DG at the rate to achieve desired weed control, but not to exceed tolerance rate listed in the table below. Wildflower injury can be reduced or eliminated with pre-emergence applications. To minimize injury, apply PLATEAU DG at 0.5 to I water soluble packet per acre at planting to tolerant species listed below. Use the 0.5 water soluble packet per acre rate under cool dry conditions and in low rainfall areas. If postemergence application is made to established prairiegrasslwildflower mixtures, use the lowest rate of PLATEAU DG necessary to achieve desired weed control (see "WEEDS CONTROLLED" section). Postemergence application can result in stand. thinning or death due to vast variation in seed sources, varieties and genotypes. It is recommended that a small area be tested prior to full application for tolerance of desired species. The rates listed below are for those species in which acceptable tolerance has been confirmed on the varieties/genotypes being treated. Application of PLATEAU DG in conjunction with an organophosphate insecticide may cause an IOcrease 10 wildflower injury. 14 2/00

) ) ) Due to the diversity of species and varieties which exist in areas where wildflowers are grown, the response to PLATEAU DG may vary greatly. Careful testing on desirable species is recommended to determine if area-wide applications can be made. Try on a limited area to verifY tolerance in a specific area. The suitability of PLATEAU DG use on wildflower species not listed, should be determined by treating a small number of such wild flowers at an appropriate rate, not to exceed 3 water soluble packets per acre per year. Treated wildflowers should be evaluated I to 2 months following application' for possible injury. THE USER ASSUMES RESPONSIBILITY FOR ANY DAMAGE OR OTHER LIABILITY. SPECIAL WEED CONTROL ALWAYS ADD AN ADJUVANT to PLATEAU DG (see "ADJUVANTS" section). Research has shown Methylated Seed Oil (MSO) surfactants provide PLATEAU DG with superior control of perennial weeds. This effect is not always observed and is most prevalent on waxy leaf species, perennials and weeds under stress conditions. For the weeds listed below, it is recommended to use a MSO for best results. The use of nonionic surfactants or silicone based surfactants may result in less than acceptable control. Johnsongrass & Itchgrass: For best results, apply PLATEAU DG at the rate of2 to 3 water soluble packets per acre after johnsongrass or itchgrass has reached 18 to 24 inches in height at the whorl. The addition of ACCORD or ROUNDUP PRO A6s8,,1 sr RSHR~HP Prs at the rate of 8 to 16 oz per acre may improve control after culm elongation or in dense stands. Use higher herbicide rates as density increases. Larger grass than specified above can be controlled. Dallisgrass, Bahiagrass, Vaseygrass, Paspalum spp" Smutgrass: For best results, apply PLATEAU DG at the rate of 22 to 3 water soluble packets per acre postemergence after grass has reached 100% green-up. The addition of ACCORD or ROUNDUP PRO A.68rs er ReHRsH!! Pre at the rate of 12 to 16 oz per acre will improve efficacy. Use higher herbicide rates as target grass weed densities and/or maturity increase. The addition of PENDULUM herbicide will provide increased preemergence control of these grasses from seed. Leafy Spurge: For best results, apply PLATEAU DG at 2 to 3 water soluble packets per acre in the late summer or fall fall, al leasl 2 weel,s prier Ie a killiRg frest (late August through mid-October). Consecutive year applications will optimize long term control. PLATEAU DG at 3 water soluble packets per acre applied spring or fall, or I water soluble packet per acre in the spring following a 2 water soluble packets per acre fall treatment may result in excessive injury to cool season grasses in some areas. For best results, always use a methylated seed oil at 2 pints per acre. Two pints per acre of Nitrogen fertilizer (See Adjuvant Section) may also be added to the spray tank to increase leafy spurge control, however, this may increase injury to desired species of grasses and forbs. The use of nonionic and silicone based surfactants have resulted in little or no control of leafY spurge. Approximate dates for fall timing in North and South Dakota is late August through Sep.tember; for Nebraska and Iowa is mid September through mid-October. This application should be made after good soil moisture is present but prior to a killing frost. Canada Thistle: Spring applications of 3 water soluble packets per acre PLATEAU DG plus 2 pints of Methylated Seed Oil per acre applied postemergence to Canada thistle will provide control and/or suppression of above ground biomass. For best results, apply when thistle is in the rosette to early bolt. Applications made at flowering will provide knock down of existing foliage but may result in root sucker sprouting. Tall Fescue Control: Tall fescue can be controlled by using PLATEAU DG at the rate of 3 water soluble packets per acre plus Methylated Seed Oil at 2 pints per acre. The addition of Assers ACCORD, glyphosate or R8HRsHpPre ROUNDUP PRO and/or Nitrogen fertilizer (See "ADJUVANTS" Section) to the above mix will aid ') in control. Tall fescue must be actively growing for optimum control. If tall fesclie has reached slimmer _ dormancy, control may be poor. 18 2/00 /

Fall applications of PLATEAU DG at 2 to 3 water soluble packets per acre plus a ACCORD or ROUNDUP PRO A668,,1 er R8HASH!, Pre at 24 to 64 ozlA will result in best control of existing tall fescue and new germinating seedlings. With spring applications of PLATEAU DG at 2~ to 3 water soluble packets per acre, plus ACCORD ') or ROUNDUP PRO Aee8rs 8r ReHRsH" Pre at 32 to 64 ozlA, use higher rates for older, mature fescue stands and lower PLATEAU DG rates when planting forbs. When using 2 water soluble packets per acre of PLATEAU OG in the fall with ACCORD or ROUNDUP PRO A6e8rs er ReHRsH" Pre, it is recommended to apply I water soluble packet per acre PLATEAU DG in the spring at planting for annual weed and seedling fescue control. Burning the fescue stand, where permitted, the following spring, just prior to green-up, will aid in control and provide a better seedbed for planting. Mowing the fescue several times the summer before fall application, will weaken the fescue root system, making it more susceptible to herbicides. Always allow for at least 10 inches of regrowth, following the last mowing before spraying, as both PLATEAU DG and ReHRsH!, ROUNDUP products need foliage present for herbicide uptake and satisfactory control. Resistant Biotype.: Naturally occurring biotypes (a plant within a given species that has a slightly different, but distinct genetic makeup from other plants of the same species) of some weeds listed on this label may not be effecti\ely controlled by this and/or other herbicides (GHsF OUSTT") with the ALSI AHAS enzyme inhibiting mode of action. If naturally occurring ALSIAHAS resistant biotypes are present in an area, PLATEAU DG should be tank-mixed or applied sequentially with an appropriate registered herbicide having a different mode of action to ensure control. WF+ RESIDUAL BAREGROUND WEED CONTROL For sensitive areas and use around desirable vegetation PLATEAU DG at 3 water soluble packets per acre may be tank mixed with ARSHIAL hereieise, PENDULUM herbicide, SAHARf,@ hersieiae, ReMAs,,!, Pre, eS68rt, OMsl, Karme,?, ROUNDUP PRO.

For other bareground areas PLATEAU DG herbicide at 3 water ._, soluble packets per acre may be tank mixed with ARSENAL herbicide, SAHARA DG herbicide, KROV AR, } ./ OUST, TORDONT", VANQUISH or other labeled products to provide total bareground weed control. For maximum weed control, use 2 pints per acre of methylated seed oil as an adjuvant. The addition of a nitrogen fertilizer may aid in weed control (see ADJUVANTS section for recommendation). Spot Treatments: PLATEAU DG may be used to control weed encroachment in bareground or total vegetation <. control situations. To prepare the spray solution, thoroughly mix in each gallon of water I water soluble packet .") PLATEAU DG plus a methylated seed oil adjuvant. USE UNDER PAVED SURFACES Applications should be made to the soil surface onlv when final grade is established. DO NOT move soil following PLATEAU DG herbicide application. Applv PLATEAU OG herbicide in sufficient water to ensure thorough and uniform wetting of the soil surface. including the shoulder area. Add PLATEAU DG herbicide at a rate of 3 water soluble packets per acre to clean water in the spray tank during the filling operation. Agitate before spraying. If soil is not moist prior to treatment. incorporation of PLATEAU DG herbicide will improve control. PLATEAU DG herbicide can be incorporated into the soil to a depth of two inches using a rototiller or disc. Rainfall or irrigation totaling one inch is also sufficient to incorporate PLATEAU DG herbicide into the soil surface. DO NOT allow treated soil to wash or move into untreated area. USE OF PLATEAU DG ON FEDERAL CONSERVATION RESERVE PROGRAM (CRP) LAND ) PLATEAU DG may be used on Federal Conservation Reserve Program (CRP) land at rates up to I water soluble packet per acre per year (see minimum plant-back intervals below). See appropriate section of this label for 19 2/00

specific instructions for the intended use. DO NOT use rates higher than I water soluble packet per acre per year on CRP land.

DO NOT rotate to cotton at 18 months after PLATEAU DG application if less than 15 inches of rainfall or irrigation is received from the time of PLATEAU DG application through November I of the same year. If drought conditions develop the year of PLATEAU DG application, cotton may be planted 16 months after PLATEAU DG application. Use of PLATEAU DG in accordance with label directions is expected to result in normal growth of plant-back crops in most situations; however, various environmental and agronomic factors make it impossible to eliminate all risks associated with the use of this product and, therefore, plant-back crop injury is always possible. TOLERANCE OF TREES AND BRUSH TO PLATEAU DG DO NOT use PLATEAU DG on nursery, orchard, ornamental plantings, new plantings or seedling trees. It is ) suggested that PLATEAU DG be tried on a limited basis to determine tolerance in your area. PLATEAU DG may be used at rates up to 3 water soluble packets per acre for general weed control in and around established trees on roadsides, prairies and other noncropland areas used for wildlife cover, erosion control, wind breaks, etc. Tree and brush species known to have acceptable tolerance to PLATEAU DG when applied under the canopy and/or to the foliage are listed below. Tolerance is based upon trees with a minimum of 2 inch DBH. Some species may exhibit tip chlorosis and minor necrosis.
