Dctemline soil pH by laboratory analysis using a I: I soil:water suspension. SPRAYER PREPARATION AND CLEANUP Prior to application of SYNCHRONY STS, start with clean, well maintained application equipment. Immediately following application, thoroughly clean all application equipment. Postponing action, even for a few hours, only makes effective cleanup more difficult. Failure to clean spraying equipment thoroughly may result in injury to suhsequently sprayed crops. When spraying multiple loads of SYNCHRONY STS over an extended period of time, rinse the equipment with clean water at the end of the day. Leave waler in the equipment overnight to prevent deposits from drying on surfaces. When applications of SYNCHRONY STS 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 tl.e procedure below.

) SPRAY DRIFT MANAGEMENT The interaction of many equipment and weather-related factors detennincs the potential for spray drift. The aprlicator is responsible for considering allthcsc factors when making application decisions. A VOIDING SPRAY DRln IS THE RESPONSIBILITY OF ll1E APPLICATOR. IMPORTANCE OF DROPLET SIZE TIle most effective way to reduce drift potential is to apply large droplets (> I sO - 200 microns). The best drift management strategy is to apply the largest droplets that provide sufficient coveragnd control. The presence of sensitive species nearby. the environmental conditions. and pest pressure may affect how an applicator balances drift control and coverage. APPLYING LARGER DROPLETS REDUCES DRIFT POTENTIAL. BUT WILL NOT PREVENT DRIFf IF APPLICATIONS ARE MADE IMPROPERLY OR UNDER UNFAVORABLE ENVIRONMENTAL CONDITIONS! See Wind. Temperature and Humidity, and Temperature Inversions sections of this label. Controlling Droplet Size - General Techniques Volume - Use high !low rate nozzles 10 apply the highest practical spray volume. Nozzles with higher rated !lows produce larger droplets. Pressure - Use the lower spray pressures recommended for the nozzle. Higher pressure reduces droplet size and does not improve canopy penetration. WHEN HIGHER FLOW RATES ARE NEEDED, USE A HIGHER­ CAPACITY NOZZLE INSTEAD OF INCREASING PRESSURE. Nozzle Type - Usc a nozzle ')"pe that is designed for the intended application. With most nozzle types, nanower spray angles pnxiucc IJrgcr droplets. Consider using low­ drift nozzles. Controlling Droplet Size - Aircraft Number of Nozzles - Usc the minimum number of nozzles with the highest flow rate that provide unifonn coverage. ;\lozzlc Orientation - Oncnting n07lles so that the spray is emitted hackwards, parallel to the airstream will produce larger droplets than other orientations. Nonie Type - Solid stream nozzles (such as disc and core with swirl plate removed) oriented straight hack produce larger droplets than other noaic types. Boom Length - 'Inc boom length should not exceed 3/4 of the \ling or rotor length - longer booms increase drift potentia1.

However. ",any factors. including droplet size and '''Iuipment type deternline drift potential at any given wind speed. A VOID 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 tluring 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 morning. Their presence can he indicated by ground fog; however. if fog is not presen!, inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke g-~ncrator. Smoke that layers and moves laterally III a concentrated cloud (under low wind conditions) indicates an inversion. while smoke that moves upward and rapidly dissipates indicates good vertical air mixing. SHIELDED SPRA YERS 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 UllJfOml deposition of the product. AIR ASSISTED (AIR BLAST) FIELD CROP SPRA YERS Air assisted field crop sprayers carry droplets to the target via a downward directed air streatll. Some Illay reduce the potentiai for drift, but if a sprayer is ull;uitable for the application andlor set up improperly. high Jrift potential can result. It is the responsibility of the applicator to determine that a sprayer is suitahle for the intended application. is configured properly, and that drift is not occurring. Note: Air a"jsted field sprayers can affect product perfonnanec by atfcctir.g spray coverage and canopy pcnetralion. Consult the application equipment section of tim label to detenninc if use of an alf assisted sprayrr is recom mended.

) I AIR ASSISTED (AIR BLAST) TREE AND VINE SPRAYERS Air assisted tree and vine sprayers carry droplets into the canopy of trees and vines via a radially or laterally directed air stream. 111ese sprayers are not suitable for applying herbicides. In addition to the general drift management prine iples already described, the following specific practices will funher reduce the potential for drift.: Adjust deflectors and aiming devices so that spray is only directed inlO the canopy. Block ojJupward pointed noules when there is no overhanging canopy. ; Use only enough air volume to penetrale the canopy and provide good coverage. Do not aI/ow spray to go beyond the edge of the cultivated area. Spray the outside row only from outside the planting. IMPORTANT PRECAUTIONS Do not grazetreared fields or harvestfor forage or hay. Do nolappljtlJisproduct throughantypecif irrigation equipment Injury to or loss of desimble trees or vegetation may result from failure to observe the following: Do not apply SYNCHRONY STS Or dmin or flush equipment on or nar desimble trees or other planls, on areas where theu roots may extend, or in locations where the chemical may he washed or moved into contact with their roots. Do not use on lawns. walks. driveways, tennis courts or similar arcm;. Many crops are sensitive to SYNCHRONY STS. All direct or indirect contact (stich as spmy drift) with crops other than soybeans should be avoided. TIKlfoughly clean all application equipment immediately aher llse and prior to spraying crops other thn soybeans. SYNCHRONY STS is for use only on soybean varieti,,., designated as "STS". INFORMATION ON RESISTANT WEEDS When helbicides with the same mode of action arc uscd repeatedly over several yea.-s to coniiol Ule same weed species in the same field, narumlly·occurring resismt weed hiotypes may survive a correctly applied herbicide treatment, propagate. and become dominant in Ulat field. These resistant wced hiotypes lIIay not be adequately controlled. Cultural practices such as tillage, prcvc:nting weed escapes from going to secd. and usmg hcrhicidcs with differrnt modes of action within and hetween crop seasons can aid in delaying ttlC proliferation and possihle dominancc of herbicide resistant weed biotyp<'s. 0:------------,' n J STORAGE AND DISPOSAL Storage: Store product in Original container only.
