Dismiss Herbicide

Visible sedge control when you need it: right away.

Dismiss Logo
FMC Professional Solutions knows that when it comes to sedge control, your customers don’t want to wait around for results. That’s why we’ve formulated Dismiss® to help you achieve faster visible sedge control than ever before. Dismiss takes charge of yellow nutsedge and green kyllinga. Dismiss practically starts working before your eyes, producing visible results on sedges in as little as 24 to 48 hours!

Dismiss is also unique in the way it controls sedges. Not only does it attack the weed on the surface, but it also penetrates the soil and helps to control sedge tubers. This helps to prevent future outbreaks, reducing the need for re-treats down the line and minimizing additional labor and chemical costs.

Mowing Instructions
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
Before Seeding Instructions
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.
Surfactant Instructions
Temporary discoloration of some turf types may result from use of surfactants or adjuvants with Dismiss Turf Herbicide. High temperatures and high relative humidity may increase the risk of temporary discoloration. Use of surfactants is not recommended.

Cost Effectiveness:
Covers 21818 - 65217 square feet
at a cost of
$1.07 - $3.21 per 1,000 sqft
Instructions:
Dismiss Turf Herbicide will control or suppress specific annual grasses when applied at a rate of 4 to 12 fl oz/acre (0.092 to 0.275 fl. oz./1,000 sq. ft.). Apply the highest rate consistent with the rate needed for turfgrass tolerance in Table 1. Rates lower than 12 fl oz/acre (0.275 fl. oz/1,000 sq. ft.) will generally control grasses for at least 60 days. Dismiss Turf Herbicide works best if applied when the annual grasses are small (pre tiller stage) and actively growing.
Good spray coverage is needed for optimum control of grasses. Temporary discoloration of some turfgrass species may result from use of surfactant. Use of surfactants is not recommended.
