SOD PRODUCTION - POSTEMERGENCE CONTROL OF BROADLEAF WEEDS
SPARTAN CHARGE is a selective herbicide that provides postemergent contact and soil residual weed control. SPARTAN CHARGE may be applied as a burndown prior to planting, early preplant, or as a preemergent application before or after weed emergence for control of susceptible broadleaf weeds. SPARTAN CHARGE is a 3.5 pound per gallon suspoemulsion containing the active ingredients carfentrazone-ethyl and sulfentrazone. Applications of SPARTAN CHARGE must be made before crop seed germination to prevent injury to the emerging crop seedlings. When applications after planting are delayed, injury may occur if seeds are germinating or if they are located near the soil surface.
Observe all instructions, crop restrictions, mixing directions, application precautions, replanting directions, rotational crop guidelines and other label information of each product when tank mixing with SPARTAN CHARGE. In addition to general application information, refer to the specific directions of use for a particular crop/use pattern as set forth below.
GENERAL APPLICATION INSTRUCTIONS
SPARTAN CHARGE is to be mixed with water, liquid fertilizer, or mixtures of water and liquid fertilizer and applied in fallow systems or as a preplant burndown or preemergence herbicide to labeled crops. SPARTAN CHARGE provides postemergent contact and soil residual control of susceptible weed species.
Emerged, susceptible broadleaf weeds are easiest to control when they are small (less than 3 inches tall) and actively growing. Thorough coverage is essential for control of small susceptible broadleaf weeds. If thorough coverage is not achieved postemergent weed control will be poor. Always use the higher recommended rate of this product, for the appropriate soil texture and organic matter, when weed growth is dense or heavy, or when weeds are growing in an undisturbed or non-cultivated area. Reduced weed control may occur if weeds are experiencing drought stress, disease or insect damage, or when weeds are thickly covered with dust. For control of weeds not listed on the label SPARTAN CHARGE may be tank-mixed with other herbicides such as glyphosate. Read and follow all manufacturers' label recommendations for the companion herbicide(s) except for specific recommendations on the label. The use of a quality spray adjuvant is required for optimum control of emerged weeds. Refer to the individual crop recommendation sections of the label for specific adjuvant type and use rates.
The residual activity of SPARTAN CHARGE applications requires adequate moisture for herbicidal activation. The amount of residual activity is dependent on several factors. These factors include, but are not limited to, existing soil moisture at application, soil type, organic matter, and tilth. Where irrigation is not available and rainfall has not provided activation, particularly for surface applications of SPARTAN CHARGE, a shallow incorporation (less than 2”) is recommended for destruction of any existing weeds and to incorporate SPARTAN CHARGE. Herbicide incorporation will initiate the process of activation with existing soil moisture. In circumstances where rainfall has not occurred and/or irrigation is not possible, alternative or additional weed management practices may be required.
Under normal growing conditions, SPARTAN CHARGE exhibits excellent crop safety. Soil applications of SPARTAN CHARGE must be made before crop seed germination to prevent injury to the emerging crop seedlings. SPARTAN CHARGE applied after crop emergence will cause severe injury to the crop. Poor growing conditions, such as excessive moisture, cool temperatures, and soil compaction or the presence of various pathogens may impact seedling vigor. Under these conditions, the active ingredients in SPARTAN CHARGE can contribute to crop response. Refer to the specific directions of use for a particular crop/use pattern as set forth below for additional information.
Refer in the section of the label with regards to Environmental And Soil Factors Influencing Spartan Charge Applications.
Use a boom and nozzle sprayer equipped with the appropriate nozzles and screens and adjusted to provide optimum spray distribution and coverage at the appropriate operating pressures. Use nozzles that that produce minimal amounts of fine spray droplets. Do not exceed 30 psi spray pressure unless otherwise required by the manufacturer of drift reducing nozzles. Apply a minimum of 10 gallons of finished spray per acre. Use higher spray volumes when there is a dense weed population. Thorough coverage is essential for control of susceptible broadleaf weeds. Be aware that overlaps and slower ground speeds while starting, stopping, or turning while spraying may result in excessive application and subsequent crop response.
Continuous agitation is required until all spray mixture has been applied. Avoid swath overlaps. Shut off spray booms while turning, slowing or stopping, as over application may result. Do not allow SPARTAN CHARGE spray mixtures to sit overnight as settling of product and difficulty of re-suspending may occur.
To avoid injury to sensitive crops, spray equipment used for SPARTAN CHARGE applications must be drained and thoroughly cleaned with water CHARGE ammonia before being used to apply other products. See Spray Clean-out Section 23 on page 5.
Avoid all direct, and/or indirect spray contact with non-target plants.
Do not apply near desirable vegetation. Allow adequate distance between target area and desirable plants to minimize exposure.
Do not apply when wind speed favors drift beyond the area of treatment.
SPARTAN CHARGE may be applied by air using properly calibrated nozzle types and arrangements that will provide optimum coverage while producing minimal amounts of fine droplets. Apply sufficient spray volume to achieve adequate coverage. Apply a minimum of five (5) gallons of finished spray per acre. Do not apply when wind speed favors drift beyond the area intended for treatment.
SOD PRODUCTION (Except FL, CA and NY)
Maximum Use Rate For Single Application Fluid ounces of Spartan Charge Per Acre
Bentgrass, creeping; Fescue, fine; Ryegrass, perennial: 5.1
Fescue, tall ;Bluegrass; Kentucky; Bluegrass, Rough: 5.1 - 10.2
Warm Season Grasses:- 10.2 - 11.5
Spartan Charge may be applied to established seeded, sodded or sprigged turfgrasses following the second mowing for the control of key grass, sedge and broadleaf weeds. Turf grasses should have developed a good root system, a uniform stand with healthy root systems to fill in the exposed edges prior to application. Sod injury could result from application of this product on sod that is not well established or has been weakened by stresses such as unfavorable weather conditions, diseases, chemical, recent harvesting or mechanical influences.
Fescue or Tall Fescue may result in undesirable plant response.
Cool Season and Warm Season Grasses: It is important to note that not all varieties or cultivars have been evaluated under treatment with Spartan Charge. Consult university or extension weed management specialists for additional information on specific local varieties or cultivars and any other pertinent information on Spartan Charge under specific local conditions.
Applications to Reseeded, Overseeded or Sprigged Areas
Reseeding, overseeding or sprigging may be done following Spartan Charge applications to turfgrasses. If reseeding, overseeding or sprigging is done within 1 month following a Spartan Charge treatment, the establishment of desirable grasses may be inhibited. Overseeding of bermudagrass with perennial ryegrass may be done two (2) to four (4) weeks following a Spartan Charge application provided slight grass plant response can be tolerated.
Optimum reseeding and overseeding results may be obtained with the use of mechanical or power seeding equipment, and where proper soil cultivation, irrigation and fertilization practices are followed.
Good spray coverage is required for optimum control of weeds. Temporary discoloration of some sod species may result from use of surfactant. Use of surfactants is not recommended.
Postemergence Control of Broadleaf Weeds
Spartan Charge herbicide will control or suppress the weeds listed in the label when applied alone shortly after weeds have emerged. Spartan Charge may be applied at the rate of 5.1 to 11.5 fluid ounces per acre to established turf grasses for the control or suppression of broadleaf weeds. Select the correct Spartan Charge use rate from Table 12. For optimum results, Spartan Charge applications should be made shortly after weeds have emerged.
Spartan Charge may be tankmixed with other herbicides, insecticides and fungicides registered for use on turfgrasses. Read and follow the label recommendations of the tank mix partner to determine turfgrass specie tolerance, use rates and application requirements. Follow all label restrictions, use directions and precautionary statements before use.
The use of additional surfactants may cause temporary undesirable effects to turfgrasses.
Sod production areas must be established three (3) months prior to the initial treatment of Spartan Charge.
Do not apply Spartan Charge to golf course greens or tees.
Do apply Spartan Charge to turf grasses not listed on the label.
Do not apply with surfactants without on-site evaluations for spray mixture compatibility and physical effects to turf grasses.
Do not graze or feed forage harvested from Spartan Charge treated areas.
Do not apply to landscape ornamental plants or ornamental beds.
Do not harvest sod within three (3) months of Spartan Charge application.
