Revolver Selective Herbicide

Revolver Herbicide is a post emergent herbicide that selectively removes cool-season grasses from warm-season grasses. 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.
