TURF USE APPLICATION - POSTEMERGENCE CONTROL OF ANNUAL, BIENNIAL & PERENNIAL BROADLEAF WEEDS (SINGLE APPLICATION)

Limitations, Restrictions, and Exceptions

Turf Use Instructions

General Information

Dismiss South 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.

Dismiss South Herbicide is formulated as a flowable (suspension concentrate) containing 4 lbs of active ingredient per gallon. The mode of action of Dismiss South Herbicide involves uptake by both weed roots and shoots. Application of Dismiss South Herbicide requires soil moisture for activation. The amount of soil moisture required for activation following application depends on existing soil moisture, organic matter content and soil texture.

Use Precautions for Turf Use

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 Dismiss South Herbicide at the recommended use rates in a range from 0.290 to 0.450 lb a.i./acre (9.5 to 14.4 fl. oz/acre or 0.220 to 0.331 fl. oz./1,000 sq. ft).

Bahiagrass: Dismiss South Herbicide application may cause temporary discoloration to exposed leaf surfaces on certain cultivars of zoysiagrass bahiagrass, centipede and hybrid bermudagrass. Treated turfgrass will recover with new growth.

Discolored leaf tissue will be removed with mowing. To reduce potential for discoloration, do not apply Dismiss South 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.

*Dismiss South Herbicide has demonstrated tolerance on warm season turfgrasses. However, not all varieties have been evaluated. Turfgrass managers desiring to treat newly released varieties should first apply Dismiss South Herbicide to a small area prior to treatment of larger areas.

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 for up to three (3) months before an application of Dismiss South Herbicide. Do not apply this product within three (3) months of harvest.

Other Use Precautions:

Do not apply to golf course putting greens or tees.

Do not use on turfgrasses other than those listed in table 1 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 graze or feed livestock forage cut from areas treated with Dismiss South Herbicide.

Do not apply Dismiss South Herbicide North of North Dakota State Highway 13 or Minnesota State Highway 210.

Do not apply directly to landscape ornamentals or ornamental beds. Temporary turfgrass discoloration has been observed when Trinexapacethyl (Primo) has been either tank-mixed or applied within 7 days of a Dismiss South Herbicide application. It is recommended that Trinexapac-ethyl (Primo) applications be made 7 days prior to, or after Dismiss South Herbicide application to reduce risk of turfgrass discoloration.

POSTEMERGENCE CONTROL OF ANNUAL, BIENNIAL & PERENNIAL BROADLEAF WEEDS

Dismiss South Herbicide will control or suppress the listed weeds when applied alone shortly after weeds have emerged. Apply Dismiss South Herbicide at rates from 9.5 to 14.4 fl. oz/acre (0.220 to 0.331 fl. oz./1,000 sq. ft.). Do not exceed the application rate specified for the turfgrass species in Table 1. To broaden the weed spectrum and increase effectiveness for certain listed weeds, Dismiss South Herbicide may be tank mixed with other EPA registered postemergence herbicides. Control of emerged annual grass weeds may be improved by combining Dismiss South Herbicide with MSMA or Drive“. Read the label recommendations of the tank mix partner to determine turfgrass species safety, use rate and application procedures. Follow all label restrictions, use directions and precautionary statements before using these tank mixtures. Read and follow the “TANK MIXTURES COMPATIBILITY” section of the label for instructions on how to determine the compatibility of tank mixtures.
