SYNCHRONY® STS® SP and "FirstRate" herbicide For improved Ragweed and Cocklebur control, add between 0.Q75 - 0.3 oz per acre to 0.5 oz per acre SYNCHRONY® STS® SP. These tankrnixes will control up to 10" Cocklebur or Common Ragweed and up to 12" Giant Ragweed. Use a lower amount of ''FirstRate'' when weeds are less than the maximum size and under good growing conditions. Use a higher amount of "FirstRate" when weeds are approaching the maximum size andlor under unfavorable growing conditions. A good quality petroleum-based or methylated seed oil-based crop oil concentrate must be added to the tank mix at the rate of 8 pints per 100 gallons of spray solution or at 1% vlv. An ammonium nitrogen fertilizer may be added as directed under the "Spray Additives" section. SYNCHRONY® STS® SP and 2,4-DB • In soybeans at least 8" tall, SYNCHRONY1) STS® SP may be tank mixed with 1-2 fl oz per acre of2,4-DB for improved control of giant ragweed up to 4" tall, annual momingglory and other broadleaf weeds. • Applications ofSYNCHRONY® STS® SP and 2,4-DBmust include a nonionic surfactant at the rate of 2 pints per 100 gal or crop oil concentrate at 8 pints per 100 gal of spray solution (1.0% v/v). See Spray Additives. • Apply a tank mix ofSYNCHRONY® STS® SP and 2,4-DB by ground only. • In Kansas and Missouri (except the bootheel area), when conditions are excessively hot and dry ( > 90 0 P and < 30% relative humidity), make applications at the rate of2 f1 oz of 2,4-DB and SYNCHRONY® STS® SP. • The use of crop oil concentrate may increase temporary injury to soybeans. Some crop response may occur 5-7 days after application of SYNCHRONY® STS® SP and 2,4-DB to soybeans under stress. Temporary yellowing, leaf crinkling, andlor soybean growth retardation may occur following application of SYNCHRONY® STS® SP and 2,4-DB.

Precautions for 0.25 oz SYNCHRONY® STS® SP uses • A temporary crop response may occur following an application of SYNCHRONY® STS® SP to soybeans not designated "STS" in the variety name. • Applications made when the crop and weeds are under stress from moisture, cold, heat, high humidity, disease, insect pressure and prior herbicide stress may result in excessive crop response and/or reduced weed control effectiveness. • Do not tankmix "Poast Plus" with 0.25 ovacre SYNCHRONY® STS® SP unless the soybean is designated as an 4'STS" variety. 5 MIXING INSTRUCTIONS I. Fill the tank 1/4 to 1/3 full of water.

2. While agitating, add the required amount of SYNCHRONY® STS®SP.
3. Continue adequate agitation.

,-.,,'0'''''' , 4. DnPont™ SYNCHRONY® STS@ SP should be thoroughly mixed with water in the spray tank before adding any other material. As the tank is filling, add (in onler): otherherbicide(s), the required spray adjuvan~ and 1he nitrogen fertilizer where required. 5. Apply SYNCHRONY® STS® SP spray preparation within 24 bours of mixing to avoid product degradation. 6. If the mixture has settled, ihoroughly reagitate before using. Additional Use and Handling Infonnatlon for SYNCHRONY® STS® SP Water Soluble Packets Soluble Packs are contained in waterproof, resealable plastic bags, with plastic hags enclosed in a cardboard box. The individual Soluble Packs will dissolve completely in water. Open the outer resealable plastic bag, remove the required number of Soluble Packs for the desired application rate and follow the mixing instructions above. PreanaWns: • Excessive handling of the packs, or exposure to moisture, will cause breakage. • Do not touch the packs with wet hands or place them on we:: swfaces. • Protect unused Soluble Packs by resealing them in the resealable bag. APPUCATION EQUIPMENT Ground Application (See Also Spray Drift Management) Broadcast Application Postemergence in soybeans, use a minimum of I 0 gal water per acre. Under heavy weed pressure or dense crop foliage, increase minimum spray volume to 15-25 gal per acre. Use flat fan nozzles at 25-60 psi for SYNCHRONY® ST~ SP applications. For burndown applications of existing vegetation, flat fan nozzles and a minimum of20 gallons per acre are recommended so as to thoroughly wet the foliage to be burned down. Do not use flood, rain drop, whirl chamber, or controlled droplet applicator (CDA) type nozzles. Unacceptable crop injury, excessive spray drift, or poor weed control may resuh. For proper spray coverage adjust the boom and nozzle height according to the specifications listed by the nozzle manufacturer. Band Application Because band applicators spray a narrower area than broadcast applicators, use proportionately less spray solution for band applications. Carefully calibrate the band applicator to not exceed the labeled rate. Flat fan nozzles are recommended. Carefully follow the n07Zle manufacturer's instructions for nozzle orientation, distance of the n07Zies ftom the crop and weeds, spray volumes, calibration, and spray pressure for band applications. • For additional infonnation on row banders, see DuPont bulletin, "Application Accuracy - Row Banders." Aerial Application (See Also Spray Drift Management) • Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at 3-5 gal per acre. • Use a minimum of 3 gal water per acre. Under heavy weed pressure or dense crop foliage, increase the minimum spray vohnne to 5 gal per acre. Do not apply during a temperature inversion, when winds are gusty, or when other conditions could produce poor coverage andlor off-largetspray movement. ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY SYNCHRONY® STS® SP rapidly inhibits the growth of susceptible weeds. Leaves of susceptible plants yellow 3-5 dsys after application, fullowed, in controlled plants, by the death of the growing point. SYNCHRONY® STS® SP will provide complete control of suscepltble weeds in 7-21 days. Suppressed plants may remain green but will be stunted and noncompetitive. Stress affects some weeds, such as pigweed, more than others. Delay application until suess passes and weeds start to grow again. Severe stress (drought. disease, insect dsmage, or nutrient deficiency such as iron chlorosis) following application may also result in poor weed control. Do not apply S~CHRONY® STS® SP if rain is expected within 1 hour or weed control may decrease. ROTATIONAL CROP GUIDELINES 6 bnportant: Crops other than soybeans following a SYNCHRONYl') STS® SP application can vary in their sensitivity 10 low concentrations ofSYNCHRONY® STS® SP remaining in the soil.

THE IMPORTANCE OF SOIL PH Soil pH varies greatly, even within the same field. pH variations as much as 2 pH units are common. Composite soil samples taken across an entire field, such as those samples taken for soil fertility recommendations, may not detect areas of high pH. Sub­ sampling is recommended for areas ~'kely to have pH values higher than the field average. The following is a non-inclusive list of potential high pH areas where subsampling is recommended Where different soil types are evident within a field, sample soil types separately. Where conditions vary within a field, sample areas separately, such as:

• areas bordered by limestone gravel roads,

• river bottoms subject to flooding,

• low areas in hardpan soils where evaporative ponds may occur,

• eroded hillsides,

• along drain tile lines, and

• areas where drainage ditch spoil has been spread. Where lime has not been deeply incorporated, soil may exlubit significantly higher pH values in the upper 3 inches of soil. Composite soil samples taken at a 6-8 inch depth may not reflect the elevated pH near the surface. In these cases shallow sampling, the upper 3 inches, is advised. Detennine soil pH by laboratory analysis using a I: I soil:water suspension. SPRAYER PREPARATION AND CLEANUP Prior to application of DuPont™ SYNCHRONY® STS® SP, start with clean, well maintained application equipment. hnmediately following application, thoroughly clean all application equipment. Postponing action, even for a few hours, only makes effective cleanup more difficnlt. Failure to clean spraying equipment thoroughly may resnlt in injury to subsequently sprayed crops. When spraying mUltiple loads of SYNCHRONY® STS® SP over an extended period of time, rinse the equipment with clean water at the end of the day. Leave water in the equipment ovemight to prevent deposits from drying on surfaces. When applications of SYNCHRONY® STS® SP are completed and prior to using the sprayer and associated equipment for other products or for crops other than soybeans, thoroughly clean the equipment using the procedure below. STEP 1. Drain spray equipment. Thoroughly rinse sprayer, and flush hoses, boom and nozzles with clean water. Loosen and physically remove visible deposits. STEP 2. Fill the sprayer with clean water and add household ammonia (one gallon of3% active for every 100 gallons of water) or correct amount of a DuPont approved cleaner*. Flush hoses, boom and nozzles. Tum off the boom and top off the tank with clean water. Circulate through the spraying system for IS minutes. Flush the hoses, boom and nozzles with the cleaning solution. Drain the tank. STEP 3. Remove and clean nozzle., screens and strainers in a bucket of fresh cleaner and water. STEP 4. Repeat STEP 2. STEP 5. Thoroughly rinse the sprayer, hoses, boom and nozzles with clean water, several times. Clean all other associated application equipment. Take all necessary safety precautions when cleaning equipment. Do not clean near wells, water sources or near desirable vegetation. Dispose of waste rinse water in accordance with loca1 regulations. • For additional information on sprayer cleanup and a listing of DuPont-approved cleaners, see DuPont Bulletin' A Guide To Application Equipment Cleanout For DuPont Sulfonylurea Herbicides". SPRAY DRIFT MANAGEMENT The interac:ion of many equipment and weather-related factors dere:mines the potential for spray drift. The applicator i; responsible for considering all these factors when making application decisions. A VOIDING SPRAY DRIFT IS THE RESPONSIBILITY OF THE APPLICATOR. IMPORTANCE OF DROPLET SIZE The most effective way to reduce drift potential is to apply large droplas (> ISO - 200 microns). The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. The presence of sensitive species nearby. the environmental conditions, and pest pressuro may affect how an applicator halances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL, BUT WILL NOT PREVENT DRIFT IF APPLICA nONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVIROm.!ENTAL CONDmONS! See Wind, Temperature and Humidity, and Temperature Inversions sections of uus label. Controlling Droplet Size· General Techniques Volume - Use high flow rate nozzles to apply the highest practical ;pray volume. Nozzles with higher rated flows produce larger droplets. 8 Pressure - Use the lower spray pressures recommended for the nozzle. Higher pressure reduces droplet size and does not i:uprove canopy penetration. WHEN HIGHER FLOW R.\ TES ARE NEEDED, USE A HlGHER­ 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 ang'es produce larger droplets. Consider using low­ drift nozzles. Controlling Droplet Size· Aircraft Number of Nozzles - Use CIe minimum number of nozzles with the tighest flow rate that provide uniform coverage. Nozzle Orientation - Orienting nozzles so that the spray is emitted backwards, parallel to the airstream will produce larger drop lets than other orientations. Nozzle Type - Solid stream nozzles (such as disc and core with s" .. if. plate removed) oriented straight back produce larger droplets than other nozzle types. Boom Length - The boom length should not exceed 3/4 of the wing .x rotor length - longer booms increase drift potential. Application Height· Application more than lOft above the canory increases the potential for spray drift.- BOOM HEIGHT Setting the boom at the lowest labeled height (if specified) which pro\ides uniform coverage reduces the exposure of droplets to evaporation and ",;nd. For ground equipment, the boom ShOl.Ld remain level with the crop and have minimal bounce.

( WIND Drift potential increases at wind speeds ofless than 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. AVOID GUSTY OR WINDLESS CONDITIONS. Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift. TEMPERATURE AND HUMIDITY When making applications in hot and dry conditions, set up equipment to produce larger droplets to reduce effects of evaporation. TEMPERATURE INVERSIONS Drift 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 laterally in a concentrated cloud. Temperature inversions are characterized by increasing temperature with altitude and are common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the moming. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. SHIELDED SPRAYERS Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the applicator to verify that the shields are preventing drift and not interfering with uniform deposition of the product. AIR ASSISTED (AIR BLAST) FIELD CROP SPRAYERS Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may reduce the potential for drift, but if a sprayer is unsuitable for the application andlor set up improperly, high drift potential can result. It is the responsibility of the applicator to determine that a sprayer is suitable for the intended application, is configured properly, and that drift is not occurring. Note: Air assisted field sprayers can affect product performance by affecting spray coverage and canopy penetration. Consult the application equipment section of this label to detennine ifuse of an air assisted sprayer is recommended. AIR ASSISTED (AIR BLAST) TREE AND VINE SPRAYERS Air assisted tree and vine sprayers carry droplets into "oe canopy of trees and vines via a radially or laterally directed air stream. These sprayers are not suitable for applying herbicides. In addition to the general drift management principles already descn"bed, the f()llowing specific practices will further reduce the potential for drift.: • Adjust deflectors and aiming devices so that spray is only directed into the canopy. BlDek off upward pointed nozzles when there is no overhanging ClDWpy. Use only enough air volume to penetrate the canopy and provide good coverage. • Do not allow spray to go beyond the edge oj the cultivated area. Spray the outside row only from outside the planting.
