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.

Poa Annua vs. Revolver
By W. on 06/01/2018
Revolver is the best way I have found to battle Poa Annua in a Zoysia Emerald grass. Have been using Revolver for 3 years and am rating Revolver as #1! Combined with Dimension 2EW Herbicide as the pre-emergent I am totally satisfied even at the rather expensive cost. I use a 25" front throw reel mower and am very particular about the appearance of my lawn, which I planted using sod 6 years ago. My location is Southeast Georgia.

Did the trick
By Vols 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!!

Revolver Selective Herbicide
By Henry on 06/27/2011

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.

Good Stuff but pricey!

I believe I have a bentgrass problem in my bermuda, and it looks like tenacity is the only bentgrass killer. On its label, it doesn't say bermuda is one of its turf grasses. Any help would be great. I have a couple pictures of my specific bentgrass.
Tenacity can only be used on bermudagrass that is still dormant when trying to remove weeds or target grasses from it. If the bermuda is only semi dormant you will see whitening and damage to the bermuda. There are a few other potential options for you to remove the bentgrass from your bermuda lawn, though. Drive XLR8 is listed to control creeping bentgrass and has multiple rate options for it in bermuda lawns. You will need to use a Non Ionic Surfactant with the Drive XLR8 to acheive the best results. Revolver Herbicide is specifically labeled to target bentgrass as well in warm season turfs. Bonide Weed Beater Ultra is safe for use on bermuda and other turf species and specifically says to not use it on bentgrass. So while bentgrass is not listed as a target weed it makes it clear using it on bentgrass would be harmful to it.

put out a pre-emergent last fall but still had some this winter. Some of the leaves on what is currently growing are brown.
Revolver Herbicide is a post-emergent herbicide is a very good post emergent that is labeled to kill poa annua in Bermudagrass. Be sure to apply this product in temperatures above 60 degrees Fahrenheit. The mixing ratio is 0.2-0.4 fl. oz. per 1000 square feet. This will generally mix in a gallon of water.

I am hoping not to have to Roundup my entire lawn to get rid of Poa annua, it has been gaining ground over the last few years over all of my pre emergence treatment
Revolver Selective Herbicide is labeled to be used on Bermudagrass, Zoysiagrass, and Buffalograss in commercial areas only to control Poa annua and should not harm the listed tolerant grass species when used as directed on the product label.

Have areas infested with poa. Have tried general weedkiller with no avail. Bermudagrass is not dormant anymore here in TX, actively growing now.
