Xonerate Herbicide

How to apply Xonerate:

Xonerate can be applied up to four times at a 1 ounce per acre rate for bentgrass. (KBG and KBG/Ryegrass up to 2 ounce rate at two applications). It should be used on turf that has smaller percentages of Poa annua (less than 10 percent Poa annua population), while transitioning to desirable turfgrass. Rates and applications will vary by turf type - refer to the product label.

Application Steps:

• 1. Apply in spring months (early summer in northern United States).
• 2. Two to four weeks after active creeping bentgrass growth resumes.
• 3. Make applications at air temperatures of 55 -80°F. Temperatures should not exceed 80°F (KBG temp range up to 85 °F).
• 4. Repeat the application at seven-day intervals for a maximum of four applications (applications should cease once Poa annua control is at an acceptable level, no Poa annua remains, or after four applications).**
• 5. Repeat applications should be made in the opposite direction as the previous application.
• 6. Creeping bentgrass can be seeded at seven or more days after the last application of Xonerate.
• 7. Xonerate may be applied in the spring at six months after seeding creeping bentgrass in the fall months of the previous year.

**Rates and applications will vary by turf type and geography.

Note: Please read all label information carefully.

• Selective removal of Poa annua in many cool- and warm-season turfgrasses including creeping bentgrass and Bermudagrass.
• The ability to re-seed creeping bentgrass at seven or more days after the last application in roughs, fairways and tees.
• The ability to apply in the spring at six months after seeding creeping bentgrass, and other cool-season turfgrasses in the fall months of the previous year.
• Control of Poa annua within three to four weeks.**
• Cost savings associated with eliminating Poa annua may include reduced labor from less frequent mowing, reduced use of fungicides, insecticides and plant growth regulators.

**Rates and applications will vary by turf type and geography.

TURF

Recommended Turfgrass Sites

XONERATE Herbicide may be applied to tolerant turf species on golf courses, seed and sod production fields, residential sites (including home lawns), schools, playgrounds, parks, recreational areas, sports fields, common areas and grass roadsides maintaines as a lawn. Do not apply XONERATE Herbicide where annual bluegrass is maintained as a desirable turf.

Turfgrass Tolerance

Apply to turfgrasses established for six months unless otherwise directed on this label. With the exception of Kentucky Bluegrass, cool season turfgrasses established in the fall months can be treated the following spring. Kentucky Bluegrass should be established for twelve months before application of XONERATE Herbicide. The use of XONERATE Herbicide on turf that is not well established, or that has been weakened by weather, pests, diseases, chemicals, mechanical injury or other related stress factors may result in adverse turf injury. This product should only be applied to sites that are composed of the following turfgrass species unless trial use has indicated that the turf species not listed here is tolerant to XONERATE Herbicide.

Cool-Season Turfgrasses

Bentgrass, Creeping	Agrostis stolonifera
Bluegrass, Kentucky	Poa pratensis
Fescue, Fine	Festuca spp.
Fescue, Tall	Festuca arundinacea
Ryegrass, Perennial	Lolium perenne

Warm-Season Turfgrasses

Bermudagrass	Cynodon dactylon
Buffalograss	Buchloe dactyloides
Centipedegrass	Eremochloa ophiuroides

Seashore Paspalum	Paspalum vaginatum
St. Augustinegrass	Stenotaphrum secundatum
Zoyslagrass	Zoysia japonica

Cool and warm season turfgrasses have demonstrated acceptable tolerance to XONERATE Herbicide. However, not all cultivars have been evaluated.

When applies as directed under the conditions described, established turfgrasses are tolerant to this product. Temporary yellowing of the turf may occur after application. This effect is temporary and the turf wil recover in 14 to 21 days.

APPLICATIONS TO COOL-SEASON TURFGRASSES WHEN THE DAILY HIGH AIR TEMPERATURE EXCEEDS 85 DEGREE FAHRENHEIT MAY RESULT IN UNACCEPTABLE INJURY. DO NOT APPLY XONERATE HERBICIDE TO CREEPING BENTGRASS WHEN THE DAILY HIGH AIR TEMPERATURE IS EXPECTED TO EXCEED 80 DEGREE FAHRENHEIT. APPLICAIONS TO WARM-SEASON TURFGRASSES WHEN THE DAILY HIGH AIR TEMPERATURE EXCEEDS 90 DEGREE FAHRENHEIT MAY RESULT IN UNACCEPTABLE INJURY ESPECIALLY TO ST. AUGUSTINEGRASS.

RESTRICTIONS:

• Apply XONERATE Herbicide only with ground equipment.
• Do not apply this product using aerial application equipment.
• Do not apply this product through any type of irrigation system.

XONERATE Herbicide may be applied postemergence to tolerant turfgrasses at rates of 1.0 to 10.0 oz/A. See additional information for specific turfgrass species in section titled Timing and Rates of Application.

Mixing Instructions—Liquid Carriers

XONERATE Herbicide is a water dispersible granule formulation that must be mixed in water.

The proper mixing sequence for XONERATE Herbicide and recommened tank mixtures with the appropriate liquid carrier is as follows:

1. Fill the spray tank or nurse tank 1/4 full with the appropriate liquid carrier or water.

2. Start the recirculation and agitation system and continue throughout mixing and application.

3. If the compatibility test indicated the need for a compatibility agent, add the recommended amount to the spray tank.

4. Add the recommened quantity of XONERATE Herbicide to the spray tank.

5. If tank mixing with wettable powders, dry flowables or water dispersible granule products in water as the carrier, these may be added now.

6. If tank mixing with suspension concentrates, add the products to the spray tank.

7. If tank mixing with emulsifiable concentrates or soluble products, add the products to the spray tank.

8. XONERATE Herbicide and all registered mixtures should be kept agitated once mixed and then sprayed out.

9. Do not allow mixtures to stand for prolonged periods of time.

SPRAY APPLICATION

Broadcast Treatment

Accurately calibrate the sprayer prior to mixing the herbicide treatments. Apply XONERATE Herbicide and the labeled tank mix partners in a minimumof 20 gal of total spray volume/A using broadcast boom equipment. Power sprayers equipped with a spray wand/gun may also be used for broadcast or spot application. Application must be made at a sufficient spray pressure and volume to provide accurate and uniform application of spray particles to a given area without causing spray drift to non-target areas. If mixed with other labeled herbicides, the spray volume may be no less than the minimum volume recommended by any tank mix product used or 20 gal, whichever is greater. Use appropriately sized mesh screens and in-line strainers. Agitate thoroughly before and during application with either bypass or mechanical agitation. Rinse the sprayer thoroughly with clean water immediately after each use. Impoper spray pattern overlaps produce areas of over-application and may increase the potential for turf damage.

Spot Treatment

Backpack and compression sprayers may be used for small turfgrass areas and spot treatments. Wands fitted with a flat flan nozzle tip should be held stationery at the proper height during application. A side-to-side or swinging arm motion may result in uneven spray coverage.

APPLICATIO METHODS AND TIMINGS

Frequently Asked Questions

Q. What is the active ingredient in XONERATE?
A. Amicarbazone 70 WDG.

Q. When is the preferred time of year to apply XONERATE to creeping bentgrass?
A. XONERATE should be applied in the spring months, although early summer is acceptable in the extreme northern United States.

Q. What is the preferred air temperature for applying XONERATE to creeping bentgrass?
A. Daytime air temperatures should range from 55 - 80° F.

Q. Is the use of a nonionic surfactant required for XONERATE?
A. A nonionic surfactant is not required but may be included with XONERATE. Good results have also been obtained in creeping bentgrass fairways when a light irrigation (approx. 0.1 inch of water) has been applied immediately after application. If immediate irrigation is to be used, it is not necessary to add a nonionic surfactant.

Q. When can I expect the Poa annua to be eliminated?
A. Results will vary by geography and time of year, but normally you can expect XONERATE to eliminate Poa annua within three to four weeks.

Q. When can I begin re-seeding creeping bentgrass after application?
A. You can begin re-seeding seven days after the last application of XONERATE.

Q. I have a heavy Poa annua population. Is XONERATE recommended?
A. Until users become familiar with XONERATE activity on Poa annua, applications are not recommended for populations greater than 10 percent.
