It may be used to remove cool-season grasses from bermudagrass greens, teeboxes, collars and approaches surrounding bermudagrass greens. Results are quick — generally apparent within one to two weeks. Can be used safely to control weed grasses on Bermudagrass, Zoysiagrass and Buffalograss.

When can I use Revolver?

Turf managers can use Revolver anytime the temperature is warm enough. If using Revolver as a transition aid, applications are made in the spring. When using it to remove undesirable grasses in actively growing bermudagrass or zoysiagrass, Revolver can be applied anytime the weeds are present. Two or more applications of Revolver six to eight days apart may be needed to control goosegrass.

How fast does Revolver work?

Speed of removal depends on air temperature. Warmer temperatures lead to faster removal. At temperatures of 70 degrees F and higher, removal of undesirable cool-season grasses can take place in one week or less. If temperatures are 60 degrees F. or lower, removal could take two to three weeks or longer. Turf managers are best advised to use Revolver as a transition aid when warm-season grasses are strongly coming out of dormancy. This timing could vary from early March in South Florida to late May in the Carolinas. On the other hand, turf managers can use Revolver to remove volunteer ryegrass – or clumpy rye – whenever the desirable grass is actively growing. It is not advisable to use Revolver during cold periods during the winter.

    3 of 5 stars  Revolver Selective Herbicide
    By Henry on 06/27/2011
    Verified Purchase

    Product is expensive $279 per quart, but effective. Revolver killed 50% of Dallis weed grass infested in Bermuda grass areas. Dosage required 5 ounces per gallon which meant the product volume didn't last very long. Application was made fairly evenly to Dallisgrass. Perhaps some Dallisgrass (regardless of maturity) received more dosage or for whatever reason didn't die.

    By Vols in East Tennessee on 05/10/2016

    One application and that ugly poanna has turned yellow. It was taking over our yard! We even applied before the daytime temperature got over 74 degrees...just could not wait to kill that nasty stuff. Yes, the price is high, but it works. The manager of our golf course told us about this product. So thanks to him and Revolver!!

QWhat is the concentration of Revolver per gallon treating tall fescue?

AYou will need to use 0.4fl oz  - 0.8 fl oz per 1,000 sq ft of area that needs to be treated. Use the higher usage rate for hard to kill weeds. The amount of water used to apply Revolver herbicide is not critical, but should be sufficient for uniform coverage of the target area. Calibrate by determining the volume of water required to treat 1,000 square feet. Use this calibration volume to determine the amount of water and Revolver herbicide needed to treat the target area (see the following calibration example). Note: Sprayer calibration (volume of spray needed to treat 1,000 square feet) will vary with each individual operator.
Steps in Calibration:
1. Mark an area of 1,000 square feet (i.e. 20 by 50 feet or 25 by 40 feet).
2. Place the sprayer on a level surface and add water noting the final level of water in the spray tank.
3. Spray the marked area with a sufficient volume of water to provide uniform coverage. Refill the sprayer to the same level as before measuring the amount of water added. The measured water added to the sprayer is the volume needed to cover 1,000 square feet.
4. Determine the application rate (0.4fl oz  - 0.8 fl oz per 1,000 sq ft.) for Revolver from the Recommendations section of this label.
5. To each volume of water used as measured in step 3, add the amount of Revolver as determined in step 4.
Example: If the sprayer uses 1 gallons of water to cover 1,000 square feet and the desired application rate of Revolver is .8 fl oz/1,000 square feet, then you would add .8  fluid ounces of Revolver to every 1 gallon of water to be used."

QWhen and how much irrigation after application?

ARevolver Selective Herbicide does not require irrigation after application. Be sure you apply the product in an ample amount of water to insure even coating of the leaves of target plants and even distribution over the area to be treated.

QWill Revolver Selective Herbicide work in temperatures varying between 25-50 degrees?
Will it be effective on poa annua now, or should I wait? I don't want poa annua to get established.

AAccording to the manufacturer  "For best results to control mature weeds, apply in spring or through fall when the daily average temperature is above 70 degrees." When the plants are not actively growing or they have gone dormant, selective herbicides like Revolver are not very effective.

QWhen using for spot treatment, how much Revolver should be mixed per gal. of water?


Revolver is labeled for application at 0.1 to 0.6 ounce per 1,000 square feet. Use the higher rates for control of goosegrass and other hard to control species. In most cases, rates of 0.2 to 0.4 ounce per 1,000 square feet are recommended for control of ryegrass, tall fescue, Poa annua (bluegrass), and Poa trivialis.

QNeed to get rid of Dallis grass in bermuda lawn. Should I mix Revolver w/ another herbicide to apply?
how much per gallon?


Because dallisgrass is a perennial plant, persistence is required to kill it with cultural practices. In lawn areas the clumps can be removed by digging. Mowing the turfgrass will not remove dallisgrass, but when turfgrass is mowed at its optimum height, it is better able to resist an invasion of this weed.

The Revolver Herbicide label does not indicate using any additional surfactants or herbicides when treating for Dallisgrass. 

Dallisgrass Suppression: Revolver used in late summer or early fall will provide suppression of dallisgrass when used in spot treatments. Use Revolver Herbicide at 1.5 – 2.0 fl oz of product per gallon of water and spray to wet followed 7– 14 days later with an additional spot treatment. If regrowth occurs a third application may be necessary.
