General Information

SOLITARE HERBICIDE is a selective post- emergence herbicide which controls annual grasses, broadleaf weeds and sedges in established turf areas including, but not limited to, residential, commercial and institutional lawns, athletic fields, commercial sod farms, golf course fairways and golf course roughs.

SOLITARE HERBICIDE is formulated as a 75 WG (Water Dispersible Granule) containing 0.75 lbs of active ingredient per pound of product. SOLITARE HERBICIDE is absorbed by shoots , foliage and roots.

A post emergent application of SOLITARE HERBICIDE is improved when adequate soil moisture is present at application. Best weed control results will be obtained when no rainfall or irrigation occurs within 24 hours after application. If no rainfall or irrigation occurs within 7 days after application of SOLITARE HERBICIDE in the amount of 0.5 inches, then irrigation of at least 0.5 inches is recommended.

Mixing and Application Instructions


For best results, fill spray tank with one fourth of the volume of clean water needed for the area to be treated. Start the agitation system and add SOLITARE HERBICIDE to the tank. Make sure SOLITARE HERBICIDE is thoroughly mixed before application or before adding another product to the spray tank.

Ground Equipment

Power sprayers: Uniform and accurate spray coverage requires proper calibration, agitation and operation of spray equipment. The use of marker dyes or foams can improve application accuracy. Boom sprayers equipped with appropriate flat fan nozzles, tips and screens are ideal for broadcast applications. Power sprayers fitted with spray wand/gun may also be used for broadcast application after careful calibration by the applicator. Power sprayers fitted with spray wand/gun are suitable for spot treatments.

Hand operated sprayers: Backpack and compression sprayers are appropriate for small turfgrass areas and spot treatments. Wands fitted with a flat fan nozzle tip should be held stationary at the proper height during application. A side to side or swinging arm motion can result in uneven coverage.

Apply this product in a sufficient volume of carrier solution to provide a uniform spray distribution. Spray volumes of 20 – 175 gallons per acre (0.5 to 4.0 gal/1,000 ft2) with spray pressures adjusted to 20 – 40 psi are appropriate. Apply the higher spray volumes for dense weed populations.

Turfgrass Safety

This product may be used on seeded, sodded or sprigged turgrasses that are well established. First application of this product can be made following the second mowing providing the turfgrass has developed into a uniform stand with a good root system. Turfgrass injury could result from application of this product on turfgrass that is not well established or has been weakened by stresses such as unfavorable weather conditions, disease, chemical or mechanical influences.

When applied as directed under the conditions described, the following established turfgrasses are tolerant to SOLITARE HERBICIDE at the recommended use rates in a range from 0.750 to 1.50 lb a.i./acre (16.0 to 32.0 ozs/acre or 0.367 to 0.735 oz./1,000 sq. ft.).

SOLITARE HERBICIDE has demonstrated tolerance on both cool and warm season turfgrasses. However, not all varieties have been evaluated. Turfgrass managers desiring to treat newly released varieties should first apply SOLITARE HERBICIDE to a small area prior to treatment of larger areas.

Treated turfgrass will recover with new growth. Discolored leaf tissue will be removed with mowing. To reduce potential for discoloration, do not apply SOLITARE HERBICIDE on turfgrass that is weakened by weather, mechanical, chemical, disease or other related stress. Maintain proper cultural practices such as adequate moisture and fertility levels to promote healthy turf growth.

Application to reseeded, overseeded or sprigged areas:

Reseeding, overseeding or sprigging of treated areas within one (1) month after application of this product could inhibit the establishment of desirable turfgrasses. Overseeding of bermudagrass with perennial ryegrass at two (2) to four (4) weeks after an application can be done if slight injury to perennial ryegrass can be tolerated.

Best results are obtained for reseeding or overseeding when mechanical or power seeding equipment (slit seeders) are used to give good seed to soil contact and proper soil cultivation, irrigation and fertilization practices are followed.

Sod Production:

This product may be applied to established sod. Allow sod to establish a good root system, a uniform stand and to fill in the exposed edges. It is recommended that sod be established forup to three (3) months before an application of SOLITARE HERBICIDE. Do not apply this product within three (3) months of harvest.

Restrictions and Other Use Precautions:

Do not apply to golf course putting greens, collars or tees.

Do not use on turfgrasses other than those listed on the label.

Do not apply to turfgrasses under stress.

Do not apply with surfactants unless previous experience has demonstrated combinations with surfactant to be physically compatible and non-injurious to the grass type in question.

Do not treat pastures, rangeland, or other areas grazed or harvested for livestock forage or hay.

Do not apply directly to landscape ornamentals or ornamental beds.

Do not allow spray drift to contact landscape ornamentals, shrubs and trees.

Temporary turfgrass discoloration has been observed when trinexapacethyl products have been either tank-mixed or applied within 7 days of a SOLITARE HERBICIDE application. It is recommended that trinexapac-ethyl applications be made 7 days prior to, or after SOLITARE HERBICIDE application to reduce risk of turfgrass discoloration.

Do not use clippings as mulch or compost around flowers, ornamentals, trees or in vegetable gardens.


SOLITARE HERBICIDE will control or suppress sedges (Table 3 of the label) when applied at a rate of 0.750 to 1.50 lb a.i./acre (16.0 to 32.0 ozs/acre or 0.367 to 0.735 oz./1,000 sq. ft.). Apply the highest rate consistent with the rate needed for turfgrass safety in Table 1 of the label. Rates lower than 16.0 oz/acre (0.367 oz/ 1,000 sq. ft.) will generally control sedges for up to 60 days. A rate of 16.0 oz/acre (0.367 oz/1,000 sq. ft.) will provide approximately 75% control for up to 60 days. Yellow nutsedge (Cyperus esculentus) is the most susceptible sedge species.

Good spray coverage is needed for optimum control of sedges. Temporary discoloration of some turfgrass species may result from use of surfactant. Use of surfactants is not recommended.
