Dismiss Herbicide

Dismiss Herbicide: A Strong Sedge Killer

Dismiss Herbicide, by FMC is a selective, post-emergent herbicide which controls broadleaf weeds and sedges in established turf areas including but not limited to, residential and institutional lawns, athletic fields, commercial sod farms, golf course fairways and golf course roughs.


Dismiss turf herbicide is formulated as a flowable (suspension concentrate) containing 4 lbs of active ingredient per gallon. The mode of action of Dismiss herbicide involves uptake by both weed roots and shoots. 


Dismiss Herbicide is regarded as one of the best herbicides for sedge weed control in residential and commercial turf. Problematic sedges such as green kylinga and yellow nutsedge are eliminated in as quickly as one to two days. Not only does Dismiss Herbicide attack the surface of the weeds but it goes even further, getting into the soil to penetrate the sedge tubers. This penetrating soil action helps to prevent additional outbreaks of sedges.


While Dismiss is labeled for the control or prevention of over 45 different broadleaf weeds and grasses, it is especially effective in eliminating sedge. It is tolerated on both warm and cool season kinds of grasses ( 13 common turfgrasses). See the label for listings and restrictions.

A shopper on Aug 11, 2018
BEST ANSWER: You will want to follow the maximum rate per acre recommendations found on the label, you would not want to reapply any sooner than 14 days.
Should I use a surfactant with Dismiss?
Mike on Jun 30, 2017
BEST ANSWER: You are correct the as stated on the label is not recommended with high temperatures.
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.
how long after application can I reseed with fescue?
Scott J on Aug 21, 2018
BEST ANSWER: 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

Will Dismiss kill the bulbs of Star of Bethlehem if I use it as a post emergent?
Jamie B on Apr 1, 2018
BEST ANSWER: April is the best time to apply them when the weeds are young and fairly tender. Dicamba or a mixture of Dicamba and 2, 4-D are the best herbicides to try. They often do not give complete eradication and repeated treatments may be necessary. It is listed on the Dismiss label, so it should work, just recommend multiple applications for control control.
What tempeture is too warm to apply dismiss on fescue lawns?
Robo on Jun 9, 2017
BEST ANSWER: High temperatures and high relative humidity may increase the risk of temporary discoloration. Would recommend not applying when temperature are over 95 degrees and it appears that your lawn might be stressed.
After treating kyllinga with Dismiss do the seed heads become inviable or do I need to try to harvest/remove them by bagging the next mowing?
Bill on Dec 1, 2016
BEST ANSWER: Dismiss is not a pre-emergent and will not stop the seeds from germinating, you can apply a good pre-emergent called Prodimaine to the areas, in early spring and late fall.

Effective product
This is the only product we've found that is truly effective on clover in a buffalograss lawn.

worth the effort
After using other weed killers, Dismiss did kill the nut-grass but left the yard in a combat zone. St Augustine plugs are not growing even when Miloganite was applied but the unaffected grass area is growing well.
