Product Overview

Prime Source Triad SFZ Select Herbicide is a water-based formula that provides selective postemergence control of broadleaf weeds on residential lawns, golf courses, sports turf, sod farms, and non-crop industrial sites. It features a powerful combination of four active ingredients including 2,4-D, Dicamba, MCPA and Sulfentrazone which helps eliminate hard-to-control weeds but will not harm established turfgrasses. It shows visible signs of weed injury within hours of application and total kill within 10-14 days. It also shows better cool-weather performance and turfgrass safety on both cool season and warm season grasses. This weed killer is rainfast in as little as 6 hours to ensure efficiency even after a downpour. Effective against a broad range of tough weeds such as beggarweed, dandelion, chickweed, carpetweed, black medic, knotweed, plantain, oxalis, chicory, clover, cocklebur, thistle, henbit, plantain, spurge, ground ivy, groundsel, curly dock, red sorrel, and more. Available in a 1-gallon jug.

DIRECTIONS FOR USE:

WHERE TO USE:

This product provides selective broadleaf control in warm-season and cool-season turfgrass in five 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, roughs) and office buildings.
  • Ornamental sites include turfgrass established around residences, parks, streets, retail outlets, cemeteries, industrial and institutional buildings, recreation areas, fairgrounds, areas adjacent to athletic fields and paved areas.
  • 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.
  • Non-cropland Sites. Highway rights-of-way (principal interstate, county, private and unpaved road). Roadsides, roadside ditches, road shoulders, road embankments, dividers, medians, parking areas and paved areas. Municipal, State and Federal lands. Airports, airfields, military installations. Fuel storage areas. Fencerows. Industrial sites (including but not limited to lumber yards, tank farms, storage areas, vacation lots and production facilities). Utility and pipeline rights-of-way.

SITE RESTRICTIONS:

  • Do not apply to any body of water including lakes, streams, rivers, ponds, reservoirs or estuaries (salt water bays). Do not apply to any shorelines (non-cropland 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, marshes).
  • Do not apply to agricultural irrigation water or on agricultural irrigation, ditch banks and canals.
  • Do not apply to agricultural drainage water or on agricultural ditch banks.

TURFGRASS TOLERANCE:

The turfgrass tolerance to this product may vary and temporary turfgrass yellowing may occur on certain varieties of hybrid bermudagrass. Adverse environmental conditions may reduce the selectivity on the turfgrass. Do not apply this product to stressed turf.

Certain spray tank additives (adjuvants, wetting agents, surfactants), liquid fertilizers, tank mixtures containing emulsifiable concentrates may reduce the selectivity on the turfgrass. Do not use adjuvants and spray additive tank-mix combinations unless your experience indicates that the tank mixture will not result in turf injury.

RESTRICTIONS:

  • Do not apply this product to bentgrass greens or tees. St. Augustine Grass, carpetgrass, dichondra legumes and lawns where desirable clovers are present.
  • Do not broadcast apply this product when temperatures are above 90°F (some injury may be expected with spot treatments when air temperatures exceed 90 degrees Fahrenheit).
  • Aerial application is prohibited.

PRECAUTIONS:

  • To avoid turf injury, use only on turfgrass that is reasonable free of stress from diseases, insects, excess heat or cold, drought or excess rainfall/irrigation, shaded areas, low soil pH, nematodes, improper mowing or improper applications of fertilizer and pesticides. Injury can occur if this product is applied under any of these or other stress conditions. Under any of these stress conditions, any turf risk is assumed by the buyer and/or user.
  • Do not use this product on or near desirable plants, including contact of spray on exposed root systems or adventitious shoots within the drip line of desirable trees and shrubs, since injury may result.

STATE RESTRICTIONS:

  • New York – Only one application per year of this product is allowed. This product is not allowed to be sold, distributed or used in Nassau or Suffolk Counties.
  • California – Make broadcast applications only between March 1st and September 1st. If troublesome weeds appear during other times of the year, a spot application can be made. While irrigation is necessary and important for plant growth, apply irrigation water efficiently, so that no more than 125% of the net irrigation requirement is applied for any irrigation event. Apply efficient irrigations for six months following application of sulfentrazone containing products. Do not apply product to bare ground.
  • Arizona – Do not use this product on sod farms in Arizona.

APPLICATION SCHEDULES:

Apply this product to broadleaf weeds that are young and actively growing for best results. Spring and fall treatments under adequate soil moisture conditions are preferred to the summer treatments. Summer broadcast applications to older, drought-stressed weeds are less effective. Fall applications provide improved control for emerged winter annuals and perennials including henbit, chickweed, clover and ground ivy.

Sequential broadcast applications or follow-up applications as spot treatments at a 30-day interval are suggested 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, or any time broadleaf weeds are actively growing.

Extremes in environmental conditions (e.g. temperature and moisture) soil conditions and cultural practices may affect the activity of this product. Under warm moist conditions, herbicide symptoms may be accelerated. While under very dry conditions, the expression of herbicide symptoms is delayed. Weeds hardened off by drought are less susceptible to this product.

FOR NEWLY SEEDED AREAS:

Delay application of this product to grass seedlings until after the second mowing.

FOR NEWLY SODDED, SPRIGGED, OR PLUGGED AREAS:

Delay the application of this product to newly sodded, sprigged, or plugged grasses until three to four weeks after the sodding, sprigging or plugging operations.

RESEEDING INTERVAL

Treated areas may be reseeded three weeks after application.

IRRIGATION

Do not apply this product through any type of irrigation system.

Rain fast in as little as six hours. Do not apply this product immediately before rainfall or irrigation. If possible, do not irrigate or water the turfgrass within six to twenty-four hours after application. If dry conditions exist, a scheduled irrigation or watering twenty-four hours before and twenty-four hours after the application is suggested.

MOWING

Delay mowing two days before and until two days after the application of this product.
