SOD FARMS, ORNAMENTAL LAWNS AND TURFGRASS - WARM SEASON TURF

General Information

PRODUCT DESCRIPTION:

ShutOut contains three active ingredients including carfentrazone-ethyl that broaden the spectrum of weed control. Carfentrazone-ethyl is in the aryl triazolinone family and inhibits protoporphyrinogen oxidase (Protox), a pivotal enzyme in chlorophyll production.

ShutOut offers these advantages:

- Excellent postemergent activity with proven performance for broadleaf weed control in turfgrass.

- Superior cool weather performance.

- High selectivity (turfgrass safety) in established cool season turfgrass and warm season turfgrass.

- Good toxicological, environmental, and ecological properties compared to the standards.

- Carfentrazone-ethyl combinations provide effective weed control for common and troublesome weed species in turfgrass, e.g., spurge, pennywort (dollarweed), dandelion, and white clover.

- The speed of action (rate of phytotoxicity) and the early injury symptoms are unique features of

carfentrazone-ethyl combinations. Generally, plant death can occur within 7 - 14 days.

GROUND EQUIPMENT:

Spray distribution: The accuracy and uniformity of the herbicide application is the sole responsibility of the applicator.

Power sprayers fitted with a boom or spray wand/gun may be used for broadcast applications and spot treatments. For best spray distribution and coverage, select a spray volume and delivery system that will ensure accurate and uniform coverage. Boom sprayers equipped with appropriate flat-fan nozzles, tips, and screens are suitable for broadcast applications.

- Calibration and proper application are essential when using this product.

- Over-application or rates above those recommended on the label can cause turf injury.

- Hand-held technique: Wands fitted with flat-fan nozzle tips may be used with the appropriate technique. Flat-fan nozzles should not be waved in a back-and-forth motion, or in a side-to-side motion, or in a swinging arm motion. Instead, the nozzle should be held stationary at the proper height. Side-to-side motion results in uneven coverage.

Spray volumes of 20 - 175 gallons per acre with spray pressures adjusted to 20 - 40 psi are appropriate.

Use higher spray volumes for dense weed populations.

Hand operated sprayers including backpack sprayers, compression sprayers, and knapsack sprayers are appropriate for small turfgrass areas when power equipment is unavailable, uneconomical, or impractical. This product may cause injury to susceptible/nontarget plants at the use site by contacting the foliage, stems, or roots. To prevent injury to susceptible crops and other desirable broadleaf plants including but not limited to cotton, legumes, tobacco, tomatoes, garden/vegetable crops, and ornamentals (flowers, trees, and shrubs) avoid contact with the spray solution, spray droplets, and spray mist (fine droplets).

Applications are recommended only when there is no potential hazard from spray drift during dormant and active growth periods. Do not apply when conditions are conducive to spray drift from the use site to untreated areas.

After using this product, clean sprayer with soap or detergent and water, or an approved spray tank cleaner and rinse thoroughly before applying other pesticides.

WHERE TO USE:

ShutOut provides selective broadleaf control in warm season and cool season turfgrass in five (5) use sites.

- Institutional sites are defined as turf areas around properties or facilities providing a service to public or private organizations including, but not limited to hospitals, nursing homes, schools, museums, libraries, sport facilities, golf courses (fairways, aprons, and roughs), and office buildings.

- Ornamental sites include turfgrass established around residences, parks, streets, retail outlets,

cemeteries, industrial and institutional buildings, recreation areas, fairgrounds, and areas adjacent to athletic fields.

- Residential/domestic sites are defined as areas associated with the household or home life including, but not limited to apartment complexes, condominiums, and patient care areas of nursing homes, mental institutions, hospitals, or convalescent homes.

- Agricultural site: Commercial sod production

- Noncropland Sites: Highway rights-of-way (principal, interstate, county, private, and unpaved roads): Roadsides, roadside ditches, road shoulders, road embankments, dividers, and medians. Municipal, state, and federal lands: Airports and military installations.

Prohibitions of Sites:

- Do not apply to any body of water such as lakes, streams, rivers, ponds, reservoirs, or estuaries (salt water bays). Do not apply to any shorelines (noncropland sites adjacent to the edges of a body of water) for lakes, streams, rivers, ponds, reservoirs, or estuaries (salt water bays).

- Do not apply to wetlands (swamps, bogs, potholes, or marshes).

- Do not apply to agricultural irrigation water or on agricultural irrigation ditchbanks and canals.

- Do not apply to agricultural drainage water or on agricultural ditchbanks.

Turfgrass tolerance:

- The turfgrass tolerance to ShutOut may vary and temporary turfgrass yellowing may occur. Environmental conditions and certain spray tank additives (e.g., adjuvants, wetting agents, surfactants), liquid fertilizers, and tank-mixtures containing other emulsifiable concentrates may

reduce the selectivity on the turfgrass.

Prohibitions:

- Do not apply this product to St. Augustinegrass, bentgrass greens, carpetgrass, dichondra, legumes, and lawns where desirable clovers are present.

APPLICATION SCHEDULES:

Early postemergent applications of ShutOut are recommended for annual, biennial, and perennial weeds. Apply ShutOut to broadleaf weeds that are young and actively growing for the best results.

ShutOut combines a contact herbicide with systemic herbicides and provides little or no residual activity at recommended use rates.

ShutOut may be applied as a single broadcast application or as a split/sequential broadcast applications in the spring, summer, or fall. Spring and fall treatments under adequate soil moisture conditions are preferred to the summer treatments. Generally, summer broadcast applications to older, drought stressed weeds are less effective.

Sequential broadcast applications or follow-up applications as spot treatments at a 2 - 6 week interval are recommended for more mature weeds, for dense infestations, and for adverse environmental conditions.

Spot treatments during the summer may be appropriate for sparse infestations, or as a follow-up

treatment anytime broadleaf weeds are susceptible.

Extremes in environmental conditions e.g., temperature and moisture, soil conditions, and cultural

practices may affect the activity of ShutOut. Under warm moist conditions, herbicide symptoms may be accelerated. While under very dry conditions, the expression of herbicide symptoms is delayed, and weeds hardened off by drought are less susceptible to ShutOut.

For newly-seeded areas:

The application of ShutOut to grass seedlings is recommended after the second mowing.

For newly-sodded, sprigged, or plugged areas:

The application of ShutOut to newly-sodded, sprigged, or plugged grasses should be delayed until 3 to 4 weeks after the sodding, sprigging, or plugging operations.

For dormant turf:

This product may be applied to fully dormant bermudagrass, fully dormant zoysiagrass, and fully dormant bahiagrass.

Reseeding interval:

Treated areas may be reseeded 2 weeks after application.

Prohibitions for application schedules:

Do not broadcast apply when air temperatures exceed 90°F; some injury may be expected with spot treatments when air temperatures exceed 90°F

HOW MUCH TO USE - USE RATES AND SPRAY VOLUMES FOR TURFGRASS:

Generally, the lower application rates within the specified range will provide satisfactory control of

sensitive weed species. The higher application rates within the specified range will be required for dense infestations of perennial weeds, for adverse/extreme environmental conditions, or for weeds beyond the appropriate growth stages.

The maximum application rate to turf is 1.0 pound 2,4-D acid equivalent per acre per application per site.

The maximum number of broadcast applications per treatment site is 2 per year.

The maximum seasonal rate of carfentrazone-ethyl contained in this product with two (2) broadcast applications to turfgrass is 0.062 pounds of carfentrazone-ethyl per acre per season. The retreatment interval for sequential broadcast applications of this product on turfgrass is two (2) to six (6) weeks depending upon the growth stages of the target weeds.
