Do not contaminate water by cleaning of equipment or disposal of wa.tes. DIRECTIONS FOR USE It is a violation of federal law to use this product in a manner inconsistent with its labeling. TELAR should be ,.sed only in accordance with recommen­ dations on this label or in separate published DuPont recom­ mendations available through local suppliers. Do not use on food or feed crops. GENERJ\L INFORMATION DuPont Telar" Herbicide is a dispersible grar.ule that is mixed in water and applied as a spray to control many annual. biennial. and perennial broad leaf weeds on nonerop. industrial sites such as airpons, military installations, fence rows, roadsides and associated rights-or-way, lumberyards. petroleum tank farms. pipeline and utility rights-of-way, pumping installations, railroads, storage areas, ~iant sites and other similar areas in~luding governmental a.~·j private lands. TELAR is noncorrosive. nonflammable, nonvolatile ,md docs not freeze. TELAR can be applied as a preemergence or i,o,;elllcl'gcncc treatment. For best results. apply TEL.AR before or during early stages of weed growth. The degree and duralin" of control may depend on the following: usc rate • weed spectrum and size at application environmental conditions at and following trratmc~t I

. .. ,. ,. Environmental Conditions and Biological Activity TELAR is absorbed by both the roots and foliage of plants. rapidly inhibiting the growth of susceptible weeds. Two to 3 weeks after application to weeds. leaf growth slows. and the growing points tum reddish-purple. Within 4 to 6 weeks of application. leaf veins and leaves become discolored. and the growing points subsequently die. Warm. moist conditions following treatment enhance the effec­ tiveness of TELAR since moisture canies TELAR into weed roots. preventing roots from developing. Cold. dry conditions delay the activity ofTELAR. Weeds hardened off by cold weather or drought stress are less susceptible to TELAR. Resistance When herbicides with the same mode of action are used repeat­ edly over several years to control the same weed species in the same field. naturally-occurring resistant weed biotypes may survive a correctly applied herbicide treatment. propagate. and become dominant in that field. These resistant weed biotypes may not be adequately controlled. Cultural practices such as tillage. preventing weed escapes from going to seed. and using herbicides with different modes of action within and between crop seasons can aid in delaying the proliferation and possible dominance of herbicide resistant weed biotypes. APPLICATION INFORMATION NONCROp, INDUSTRIAL SITES TELAR is recommended for control of many annual. biennial. and perennial broadleaf weeds in noncrop. industria! dTCas. Application Timing Apply TELAR as a preemcrgent or early postcmcrgent spmy when weeds are actively genninating or growing.

Do not apply TELAR to turf less than 1 year old. • GrdSS seed may be planted in treated areas 6 months after treatment, cultivation is recommended. For broadcast applications. do not exceed 112 oz TELAR per acre within a 12-month period. For those weeds listed under the 1- to 3-oz recommendation in the Noncrop.lndustrial Sites section of this label. spot treatment (at that rate) is recommended. Do not make broadcast applications to turf at 1- to 3-oz as this may cause excessive turf injury. SPRAY EQUIPMENT Apply TELAR using ground equipment only. Equipment used to apply TELAR should not be used for application to crops following a TELAR application. as even low rates of TELAR can kill or severely injure most crops (except small grains). BROADCAST APPLICATION Use 10 to 40 GPA when applying TELAR as a broadcast appli­ cation. Be sure to calibrate sprayers before application. Select a spray volume and delivery system that will ensUlC thorough covemge and a uniform spray pattern. When spraying industrial turf. avoid overlapping and shut off spray booms while starting. turning. slOWIng. or stopping to avoid injury to dsired species. HANDGUN APPLICATION Use 100 to 300 GPA when applying TELAR as a broadcast application via handgun. Mix I oz TELAR per I I)lIglll "r water. Apply up to 300 gal of spray mix per acre. SPRAY ADJUVANTS , Nonionic Surfactants Always include a nonionic surfactant when maki.,g ,",,'uller­ genee applications of TELAR (except for usc on 'urt). Anply at a minimum rate (concentration) of25% vlv (I qt per jOn gal of spray solution) or at the manufacturer's recommended r.lIe ba",,' on spray arca. Use only EP/\·apprnved ,urfactant., contaming at L:,,: ::0';, active ingred.ent.

Drift Control Agents To minimize drift, a drift control agent may be added at the manufacturer's reconunended rute. MIXING INSTRUCTIONS I. Fill spmy tank 112 full of water. 2. With the agitator running. add the proper amount of TELAR. 3. If using a companion product. add the recommended amount. 4. For postemergence applications. add the proper amount of spmy adjuvants (i.e. surfactants. drift control agents. etc.). 5. Add the remaining water. 6. Agitate the spray tank thoroughly. Use the spray preparation ofTELAR within 24 hours to avoid product degradation. If the spray prepa. ... tion is left standing. agitate it thoroughly before using. SPRAYER CLEANUP Thoroughly clean all mixing and spray equipment immediately following applications ofTELAR as follows: I. Drain tank; rinse interior surfaces of tank; then flush tank. boom. and hoses with clean water for a minimum of 5 mi,dteS. 2. Fill the tank with clean water and add the cleaning solution·. Flush the boom. ho~,es. and nozzles with the cleaning solution. Allow them to sit for IS minutes with agitation running. and then drain the tank. 3. Repeat Step 2. 4. Repeat Step I. 5. Remove the nozzles and screens and clean sepamtely. To remove traces of cleaning solution. rinse the 'lf1k thoroughly with clean water and flush through the hoses and boom. • Use any of the following cleaning solutions: I. One gal ammonia (containing 3% active) per 100 gal of water. 2. Nutra-sol2 (carefully read and follow Nutra-sollabel directions). 3. Loveland Spray Tank Cleaner3 (carefully read and follow Loveland Spray Tank Cleaner label directions). 4. Tank-Aid4 (carefully read and follow TaJ.·Aid label direr- tions). To reduce the amount of water required in tht above procedure. see separate DuPont bulletin. "Reduced Volume Cleanout Procedure for Large Sprayers." Note: This sprayer cleanup procedure is only effective for TELAR and for general uses spec' fied under "Directions for Use"; do not use sprayer on food ClOpS. feed crops. fine turf. omamelitals. and other desirable plants. SPRAY DRIFT MANAGEMENT The intemction of many equipment and weather-related factors determines the potential for spray drift. The applicator is responsible for considering all these fact'Jrs when making application decisions. A VOIDING SPRAY DRIFT IS TI-lE RESPONSIBILITY OF THE APPLICATOR. IMPORTANCE OF DROPLET SIZE The most effective way to reduce drift potential is to apply large droplets (> 150 - 200 microns). The best drift manage­ ment strategy is to apply the largest droplets that provide suffi· 4 cient coverage and control. The proscnce of scnsitive species nearby. the environmental conditions. and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL. BlTf WilL NOT PREVENT DRIFT IF APPLICA nONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVIRONMENTAL CONDITIONS! Sec WInd. Temperature and Humidity. and Temperature Inveuions sections of this label. Controlling Droplet Size· General Techniques • Volume· Use high flow rate nozzles to apply the highest practical spray volume. Nozzles with higher rated flows produce larger droplets. • Pressure· Use the lower spray pressures recommended for the nozzle. Higher pressure reduces droplet size and docs not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER-CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE. • Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types. narrower spray angles produce larger droplets. Consider using low­ drift nozzles. BOOM HEIGHT Setting the boom at the lowest labeled height (if specified) which provides uniform coverage reduces the exposure of droplets to evapomtion and wind. For ground equipment. the boom s~ Juld remain level with the croo:md have minimal bounce. WIND Drift potential increases at wind speeds of less tlUUl 3 mph (due to inversion potential) or more than 10 mph. However. many factors. including droplet size and equipment type determine drift potential at any given wind speed. A VOID GUSTY OR WINDLESS CONDITIONS. Note: Local terrain can influence wind patterns. Every appli­ cator should be familiar with local wind patterns 'Uld how they affect spray drift. TEMPERATURE ANu HUMIDITY When making applications in hot and dry conditions. set up equipment to produce larger droplets to reduce effects of evapo­ ration. TEMPERATURE INVERSIONS Thift potential is high during a temperature inversion. Temperature inversions restrict vertical air mixing. which causes small suspended droplets to remain close to the ground and move latemlly in a concentrated cloud. Temperature inversions are characterized by increasing tempemture with .lltitudc and arc common on nights with limited ~Ioud cover and light to no wind. They begin to form as the sun sets and often cVf1tidue into the morning. Their presence car. be indicated by ground fog; however. if fog is not present, inversions can also N: identitied by the movement of smoke from a ground souree or a, a,remft smoke generator. Smoke that layers and moves I"t~~all) in a concentrdtcd cloud (under low wind c<mditions) indical-'c an inversion. while smoke that moves upward and rapid I; dissi· pates indicates good vertical air mixing.

PRECAUTIONS Injury to or loss of desirable trees or other plants may result from the following: • If equipment is drained or flushed on or near desirable trees or other plants, on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots. • Treatment of powdery. dry soil and light, sandy soils when there is little likelihood of rainfall SOOt, after treatment may result in off target movement and possible damage to susceptible "rops when soil particles are moved by wind or water. Injury to crops may result if treated soil is washed. blown or moved onto land used to produce crops. Exposure to TELAR may injure or kill most crops (except small grains). Injury may be more severe when crops are irrigated. • Applications made during periods of intense rainfall. to soils . "j . ~ \ ,saturated with water, surfaces paved with materials such as ( r, ". ') 1 asphalt or concrete. or soils through which rainfall will not . \ \ '0 /' readily penetrtate may result in runoff and movement of \ ~ x...' TELAR. Do not treat frozen soil. Treated soil should be left l. undisturbed to reduce the potential for TELAR movement ~ \ by soil erosion due to wind or water. ~~ Do not use on lawns. walks. driveways. tennis courts, or similar areas. Do not apply in or on irrigation ditches or canals including their outer banks. Do not apply through any type of irrigation sys ""n. Do not use this product in the following counties of Colorado: Saguache. Rio Grande, Alanlosa. Costilla. and Conejos. STORAGE AND DISPOSAL Storage: Store product in original container only.
