THE PROBLEM WITH POA
Every golf course has its particular problem weed that impairs playability. For most, it’s Poa annua.
Poa produces bumpier-than-normal playing conditions, a major issue for playability.
One of the most common and widely distributed grassy weeds in the world, Poa annua is also one of
the most difficult to control on turfgrass, especially in creeping bentgrass. Bentgrass provides conditions
that are ideal for Poa annua growth, including high moisture, nitrogen, high traffic levels and routine
fungicide use. 1 There’s never been a real solution for eliminating Poa annua. Until now.
NEW CHEMISTRY. NEW STRATEGY.
XONERATE (Amicarbazone) is a post-emergent herbicide that represents a new turfgrass chemistry
for golf courses. XONERATE doesn’t just manage or suppress Poa annua, it eliminates it.
POA ANNUA
XONERATE 70 WDG contains 70% Amicarbazone in a water-dispersible granule formulation. It’s
absorbed by leaves and roots and inhibits photosynthesis in sensitive plants by interfering with
normal electron transport.
XONERATE DIFFERENCE
• Selective removal of Poa annua in many cool and warm season turfgrasses including creeping bentgrass and Bermuda grass.
• 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. 2
• Cost savings associated with eliminating Poa annua may include reduced labor from less frequent mowings, reduced use of
fungicides, insecticides and plant growth regulators.

HOW TO APPLY XONERATE
XONERATE can be applied up to four times at a 1-ounce/acre rate for bentgrass. (KBG and KBG/Ryegrass up to 2 oz rate at 2
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. 2
APPLICATION STEPS
• Apply in spring months (early summer in Northern United States), two to four weeks after active creeping
bentgrass growth resumes.
• Make applications at air temperatures of 55 – 80° F.
• Temperatures should not exceed 80° F (KBG temp range up to 85° F).
• Repeat the application at seven-day intervals for a maximum of up to four applications (applications should
cease once Poa annua control is at an acceptable level, no Poa annua remains, or after four applications). 2
• Repeat applications should be made in the opposite direction as the previous application.
• Creeping bentgrass can be seeded at seven or more days after the last application of XONERATE.
• XONERATE may be applied in the spring at six months after seeding creeping bentgrass in the fall months of
the previous year.
• XONERATE may be tank-mixed. Water is the recommended liquid carrier (please read all label information carefully).
TURF SPECIES ACCEPTABLE FOR XONERATE
XONERATE 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 Amicarbazone DF. Apply to turfgrasses established for six months unless otherwise
directed on this label. See the XONERATE label for use on specific turf species.

When applied as directed under the conditions described, established turfgrasses are tolerant to this product. Temporary
yellowing of the turf may occur 14 - 21 days after application. This effect is temporary and the turf will recover in 14 - 21 days.
Fill-in of bare spots caused by removal of Poa annua may take longer. Cultural practices directed at encouraging the growth of
bentgrass will speed up the fill-in process.

Cool- and warm-season turfgrasses have demonstrated acceptable tolerance to Amicarbazone 70DF. However, not all cultivars have been evaluated.
