Timing of application for Tribute Turf Herbicide

Tribute can be used to remove undesirable grasses such as wintergrass, ryegrass and crowsfootgrass in actively growing couchgrass, any time the weeds are present. Weed control is faster at higher temperatures. If using Tribute as a transition aid, applications are made in the spring.

Crowsfootgrass is one of the most common annual grass weeds in turf during the summer. In tropical areas the weed can be a problem all year round. Tribute symptoms on weeds develop in the first week but complete weed control can take several weeks, especially at lower temperatures. For larger crowsfootgrass plants repeat Tribute applications may be required.

Spray program and resistance management for Tribute Turf Herbicide

Tribute contains the active ingredient foramsulfuron (Group B). The product selectively removes unwanted cool-season grasses from warm-season grasses.

Speed of removal depends on air temperature. Warmer temperatures lead to faster removal. At temperatures of 21ºC and higher, removal of undesirable cool-season grasses can take place in one week or less. If temperatures are 15ºC, or lower, removal could take two to three weeks or longer.

Turf managers are best advised to use Tribute as a transition aid when warm-season grasses are strongly coming out of dormancy. On the other hand, to remove volunteer Ryegrass – or Clumpy Rye – apply whenever the desirable grass is actively growing. It is not advisable to use Tribute during cold periods in winter.

Two or more applications of Tribute 7 to 14 days apart may be needed to control some grasses.
