GENERAL INSTRUCTIONS
MONUMENT LIQUID is a selective herbicide for application after emergence of weeds, for control of certain
weeds in established turf. MONUMENT LIQUID is an oil dispersion formulation that mixes readily with water
and is applied as a spray.

The degree of control resulting from application of MONUMENT LIQUID is primarily dependent upon weed
species, weed size at application, environmental conditions, amount of MONUMENT LIQUID applied and
growing conditions. Weed control is greatly improved when weeds have emerged, ample soil moisture exists
and weeds are actively growing, rather than when the soil is dry and weeds are under stress from lack of
moisture. Growth of susceptible weeds is inhibited soon after application of MONUMENT LIQUID. The
leaves of susceptible plants normally turn yellow, red or purple after several days, followed by necrosis and
death of the growing point. Complete plant death generally occurs 2 to 4 weeks after application, depending
on the weed species, growing conditions, etc.

Apply to actively growing weeds during early stages of development for best results. For optimum
performance avoid mowing for 1 to 2 days prior to and following application.

Mode of Action
MONUMENT LIQUID controls weeds by inhibiting a biochemical process that produces certain essential
amino acids necessary for plant growth. The inhibited enzyme system is acetolactate synthase (ALS).

***

Bahia Grass (Paspalum notatum) Management
Different grasses vary in their sensitivity to MONUMENT LIQUID, Primo MAXX and Primo 250 EC. Bahia
grass is very sensitive to the combination resulting in control of seedhead as well as vegetative growth
suppression. Apply the combination as soon as seedheads start to form or when it becomes a regular
mowing intervention issue, normally during October to January. Apply at 4 week intervals after mowing.

Mixing
MONUMENT LIQUID can be tank mixed with Primo MAXX and Primo 250 EC.
MONUMENT LIQUID mixes readily with water, no pre-mixing is required.
If pH of water is less than 5.5, use a buffer solution to raise pH to near 7.0. DO NOT mix MONUMENT
LIQUID with acid forming compounds in the spray tank.
This product must be mixed with water and applied by suitable spray equipment.
1. Clean the spray tank before using. If it is contaminated with other materials, mixing problems and/or
clogging may occur, or injury to the turf may result.
2. Fill tank no more than 25% full with clean water before adding MONUMENT LIQUID. Begin agitating tank
contents vigorously and continue agitation during entire mixing and spraying operation.
3. Pour required amount of MONUMENT LIQUID steadily into tank. Allow vigorous bypass agitation to
completely disperse product.
4. After adding required quantity of MONUMENT LIQUID and obtaining complete dispersion, continue to fill
tank to desired level for spraying.
5. Add required quantity of non-ionic surfactant if using and continue agitation.
6. Thorough agitation (preferably mechanical) of the spray liquid is essential during the addition of the
product and during the entire spraying operation. Recirculate if left to stand.
Note: Spray solution should NOT be left standing in the tank overnight.
Non-ionic Surfactants: Use Agral (600 g ai/L) at 0.42% v/v or 420 mL/100 L spray mix. Alternatively use
other quality non-ionic surfactants (1000 g ai/L formulations) at 0.25% v/v or 250 mL/100 L spray mix.

Application
DO NOT apply with aircraft or through any type of irrigation equipment
APVMA Compliance Instructions for Mandatory COARSE or Larger Droplet Size Categories
These instructions inform users of this chemical product how to lawfully comply with the requirement of a
COARSE or larger spray droplet size category for spray application.
Spray droplet size categories are defined in the ASAE S572 Standard (newer name may also be shown as
ASABE) or the BCPC guideline. Nozzle manufacturers may refer to one or both to identify droplet size
categories, but for a nozzle to comply with this requirement, the manufacturer must refer to at least one.
Complying with the label requirement to use a specific droplet size category means using the correct
nozzle that will deliver that droplet size category under the spray operation conditions being used.
The APVMA has approved only the following specific methods for choosing the correct nozzle. Use
one of the methods specified in these instructions to select a correct nozzle to deliver a COARSE or
larger droplet size category.
Mandatory instructions for ground applications for COARSE droplet size or larger categories
USE ONLY nozzles that the nozzles’ manufacturer has rated to deliver a COARSE, a VERY COARSE or
an EXTREMELY COARSE droplet size category as referenced to ASAE S572 or BCPC. Choose a
nozzle specified to provide the droplet size required in the label Spray Drift Restraints.
DO NOT use a higher spray system pressure than the maximum the manufacturer specifies for the
selected nozzle to deliver the droplet size category required in the label Spray Drift Restraint.

Spray nozzles should be uniformly spaced and of the same size, and should provide accurate and uniform
application. To ensure accuracy, calibrate sprayer at the beginning of the season before use and recalibrate
frequently. Apply at a volume of 400 to 800 L water/ha. Higher volumes should be used for severe weed
infestations and higher cut turf (>15 mm) to ensure adequate spray coverage. Good weed coverage with the
spray mixture is essential for optimum weed control. Observe sprayer nozzles frequently during the spraying
operation to ensure that the spray pattern is uniform. Avoid overlapping of spray runs. Ensure that boom
height for broadcast application does not exceed 50 cm above the leaf blades of the turf. Avoid application
under conditions when uniform coverage cannot be obtained or when spray drift may occur.

Rainfastness
MONUMENT LIQUID is rainfast within 3 hours of application.

***

Instructions to Avoid Spray Drift
DO NOT allow spray to drift onto adjacent turf sites or ornamental plants as even small amounts may injure
sensitive plants. When drift may be a problem, take steps to reduce spray drift.
DO NOT apply where wind speed is less than 3 or greater than 20 km/hour at application site.
Use extreme caution when conditions are favourable for drift, ie high temperatures and low relative humidity,
especially when sensitive plants are located nearby. All plants not listed as turf species on this label should
be considered as sensitive plants.
If sensitive plants are downwind, extreme caution must be used under all conditions. Drift from applications
of this herbicide is likely to result in damage to sensitive plants adjacent to the treatment site. This damage
can occur at levels below the concentrations that can be detected with chemical analysis.
DO NOT apply when a surface temperature inversion exists. If an inversion condition is suspected, consult
with local weather services before making an application.
DO NOT apply with spray droplets smaller than a COARSE spray droplet size category according to
“APVMA Compliance Instructions for Mandatory COARSE or Larger Droplet Size Categories” located under
this title in the GENERAL INSTRUCTIONS section of this label
If conditions favour drift, recalibrate sprayer by reducing spray pressures and increasing spray volumes to
produce larger droplets.
Apply as close to surface of target turf as practical to obtain a good spray pattern for adequate coverage
according to the manufacturer’s recommendations. Ground applications are limited to a nozzle height of 50
cm above the ground.

Sprayer Cleanup
Thoroughly clean spray equipment using the following procedure when you have finished spraying highly
active materials such as sulfonylurea products. Start with a thoroughly cleaned sprayer before beginning the
next job.
1. Mix only as much spray solution as needed. Immediately after spraying, clean equipment
thoroughly using this procedure. Wear appropriate protective clothing.
As a first step, flush tank, hoses, boom and nozzles with clean water.
2. Prepare a cleaning solution of 300 mL of household ammonia/100 L water. Ensure ammonia used is
fresh as it can degrade significantly over time resulting in a reduction in cleaning ability.
3. When available, use a pressure washer to clean the inside of the spray tank with this solution. Take care
to wash all parts of the tank, including the inside top surface and lid.
4. Completely fill the sprayer with the cleaning solution to ensure contact of the cleaning solution with all
internal surfaces of the tank and plumbing. Start agitation in the sprayer and thoroughly recirculate the
cleaning solution for at least 15 minutes. All visible deposits must be removed from the spraying system
and, in cases where there is the possibility of heavy build up of residues, the cleaning solution may need
to be left in the tank for extended periods to ensure adequate decontamination of the tank.
5. Flush hoses, spray lines and nozzles for at least 1 minute with the cleaning solution.
6. Dispose of rinsate from steps 1 to 5 in an appropriate manner.
7. Repeat steps 2 to 5.
8. Remove nozzles, screens and strainers and clean separately in the cleaning solution after completing
the above procedures. Be careful with filters, as they are a main source of contamination.
9. Rinse the complete spraying system with clean water.
The above method is only effective if the cleaning solution comes into contact with every surface or
contact point that may contain even minute sulfonylurea herbicide residues. In some boom sprayers
this may not be physically possible and hence it may be advisable to use a different boomsprayer
that has not been used to spray sulfonylurea herbicides, when spraying sensitive crops or turf
species.

Compatibility
As formulations of other manufacturers’ products are beyond the control of Syngenta, and water quality
varies with location, all mixtures should be tested prior to mixing commercial quantities.

Replanting interval
DO NOT replant any crop or ornamentals to treated areas other than turfgrasses listed in the Directions for
Use for a period of 12 months after application.

Resistant Weeds Warning GROUP B HERBICIDE
MONUMENT LIQUID Turf Herbicide is a member of the sulfonylurea group of herbicides and has the ALS
Inhibitor mode of action. For weed resistance management this product is a Group B herbicide. Some
naturally occurring weed biotypes resistant to MONUMENT LIQUID and other sulfonylurea herbicides may
exist through normal genetic variability in any weed population. The resistant individuals can eventually
dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be
controlled by MONUMENT LIQUID or other Group B herbicides. Since the occurrence of resistant weeds is
difficult to detect prior to use, Syngenta Australia Pty Ltd accepts no liability for any losses that may result
from the failure of MONUMENT LIQUID to control the resistant weeds. Advice as to strategies and
alternative treatments that can be used should be obtained from your local supplier, consultant, local
Department of Agriculture, Primary Industries Department or a Syngenta representative.

PRECAUTION
Re-entry Period: DO NOT allow entry into treated areas until the spray has dried unless wearing cotton
overalls buttoned to the neck and wrist (or equivalent clothing), and chemical resistant gloves. Clothing must
be laundered after each day’s use.

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS
This product is very highly toxic to non-target plants including aquatic plants. DO NOT apply under weather
conditions or from spraying equipment that may cause spray to drift onto nearby susceptible plants/crops,
cropping lands, pastures and other non-target plants or natural and impounded lakes, dams or other
waterways. Avoid applications to areas where product may accumulate under the drip line of trees or where
product may come into contact with roots of desirable plants. Refer to Instructions to Avoid Spray Drift.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT
Very highly toxic to aquatic organisms. DO NOT contaminate streams, rivers or waterways with the chemical
or used containers. DO NOT apply if heavy rain is forecast.

STORAGE AND DISPOSAL
