General Information

DUPONT SYNCHRONY XP

Highlights

- SYNCHRONY XP provides selective PRE, PPI, Burndown, and POST weed control in soybeans. Use rates depend on weed size, weed spectrum, and desired residual control.

- SYNCHRONY XP can be used on conventional, “Roundup Ready”, STS/“Roundup Ready” stack, or STS only soybeans.

- SYNCHRONY XP used PRE, PPI, Burndown, or POST can help delay weed shift patterns that are developing from glyphosate-only applications.

- For Burndown, SYNCHRONY XP may be tank mixed with glyphosate to deliver faster, more consistent control of larger weeds, even under adverse conditions.

- SYNCHRONY XP can be used as an in-crop glyphosate tankmix partner for “Roundup Ready” soybeans that broadens the weed control spectrum on key weeds (like dandelion, hemp sesbania, lambsquarters, morningglory, pigweeds, yellow nutsedge, ragweeds, velvetleaf, and others) versus glyphosate-only applications.

- New STS/RR soybean varieties allow greater weed control options by utilizing higher rates of SYNCHRONY XP with your glyphosate application.

This tankmix will deliver faster, more consistent control of broadleaf weeds and help delay weed shifts developing with glyphosate-only applications – with complete crop safety. Ask your local seed dealer for availability of this new technology.

- Include a crop oil concentrate or a nonionic surfactant and ammonium-based nitrogen fertilizer where required.

- SYNCHRONY XP may be applied by ground (broadcast or band) or by aerial application.

- Certain environmental conditions, such as cool and dry, or hot and humid weather, affect the performance of SYNCHRONY XP. See Environmental Conditions.

- Consult label text for complete instructions. Always read and follow label directions for use.

Application Methods

- preemergence, including pre-plant incorporated.

- pre-plant and early pre-plant, including burndown.

- postemergence in-crop

- sequential preemergence followed by postemergence

Timing To Crop Stage

- SYNCHRONY XP for PRE, PPI and Burndown uses may be applied any time prior to soybean emergence.

- SYNCHRONY XP, for in-season use on STS soybeans, may be applied any time after emergence but no later than 60 days before soybean maturity.

- SYNCHRONY XP, for in-season use on non-STS soybeans, may be applied any time after the first trifoliate but no later than 60 days before soybean maturity.

Timing To Weeds

Apply SYNCHRONY XP when weeds are young and actively growing. Applications made to weeds larger than the sizes indicated below, or to weeds under stress, may result in unsatisfactory control.

Cultivation

Do not cultivate within 7 days of application. Cultivation may put weeds under stress by pruning roots, thus diminishing control.

Cultivation approximately 14 days after application will help control suppressed weeds.

APPLICATION EQUIPMENT

Ground Application

(See Also Spray Drift Management)

Broadcast Application

- Postemergence in soybeans, use a minimum of 10 gal water per acre. Under heavy weed pressure or dense crop foliage, increase minimum spray volume to 15-25 gal per acre. For best performance, select nozzle and pressure combinations that deliver medium to coarse spray droplets, as indicated, for example, by ASAE standard S572.

- Preemergence in soybeans, use a minimum of 10 gal water per acre. For best performance, select nozzle and pressure combinations that deliver coarse to very coarse spray droplets, as indicated, for example, by ASAE standard S572.

- For burndown applications of existing vegetation, use a minimum of 15 gal water per acre. For large weeds and/or heavy residue, increase gallonage to ensure coverage. For best performance, select nozzle and pressure combinations that deliver medium to coarse spray droplets, as indicated, for

example, by ASAE standard S572.

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 nozzle manufacturer’s instructions for nozzle orientation, distance of the nozzles from the crop and weeds, spray volumes, calibration, and spray pressure for band applications.

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 volume to 5 gal per acre.

- Do not apply during a temperature inversion, when winds are gusty, or when other conditions could produce poor coverage and/or off-target spray movement.

* Do not apply SYNCHRONY XP herbicide by air in the state of New York

ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY

SYNCHRONY XP rapidly inhibits the growth of susceptible weeds. Leaves of susceptible plants yellow 3-5 days after application, followed, in controlled plants, by the death of the growing point. SYNCHRONY XP will provide complete control of susceptible weeds in 7-21 days. Suppressed plants may remain green but will be stunted and noncompetitive.

SYNCHRONY XP will provide best results when applied to young, actively growing weeds. Degree of control depends on: weed spectrum; weed size (if weeds are large, use higher spray volume); growing conditions at and following treatment; soil moisture; precipitation; and spray adjuvants. Treating weeds under stress or large weeds may result in only partial control. Stress may be caused by:

- abnormal weather (hot or cold)

- mechanical injury from cultivation

- drought

- water-saturated soil

- disease

- insect injury

- prior herbicide injury

Stress affects some weeds, such as pigweed, more than others.

Delay application until stress passes and weeds start to grow again.

Severe stress (drought, disease, insect damage, or nutrient deficiency such as iron chlorosis) following application may also result in poor weed control.

Do not apply SYNCHRONY XP if rain is expected within 1 hour or weed control may decrease.

RESTRICTIONS

- Do not graze treated fields or harvest for forage or hay.

- Do not apply this product through any type of irrigation equipment.

- SYNCHRONY XP can be applied in tank mixtures with organophosate insecticides or at any time preceding or following an application of an organophosphate insecticide on any STS or STS/RR soybean variety. Tank mixtures of SYNCHRONY XP plus organophosphate insecticides applied to STS or STS/RR soybean varieties may result in minor transient crop response (i.e. stunting and/or chlorosis). Do not apply SYNCHRONY XP within 14 days before or after an application of an organophosphate insecticide on any soybean variety that is not STS or STS/RR, as severe crop injury may occur.

Injury to or loss of desirable trees or vegetation may result from failure to observe the following:

- Do not apply SYNCHRONY XP or drain or flush equipment 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.

- Do not use on lawns, walks, driveways, tennis courts or similar areas.

- Many crops are sensitive to SYNCHRONY XP. All direct or indirect contact (such as spray drift) with crops other than soybeans should be avoided.

- Thoroughly clean all application equipment immediately after use and prior to spraying crops other than soybeans.

RESISTANCE

When herbicides that affect the same biological site of action are used repeatedly over several years to control the same weed species in the same field, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that field. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different site of action.

To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes.

It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative for specific alternative cultural practices or herbicide recommendations available in your area.

INTEGRATED PEST MANAGEMENT

DuPont recommends the use of Integrated Pest Management (IPM) programs to control pests. This product may be used as part of an Integrated Pest Management (IPM) program which can include biological, cultural, and genetic practices aimed at preventing economic pest damage. Application of this product should be based on IPM principles and practices including field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop or site systems in your area.

Refer in the label regarding tank mix information.
