GENERAL INSTRUCTIONS

Mixing
CASPER mixes readily with water, no pre-mixing is required. 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 CASPER. Begin agitating tank contents
vigorously and continue agitation during entire mixing and spraying operation.
3. Pour required amount of CASPER steadily into tank. Allow vigorous bypass agitation to completely
disperse product.
4. After adding required quantity of CASPER 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.

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.

Application
DO NOT apply by air or through any type of irrigation equipment.
DO NOT apply using spraying equipment carried on the back of the user.
Ground Application: Spray nozzles should be uniformly spaced and of the same size, and should provide
accurate and uniform application. Use spray nozzles that produce no smaller than a COARSE spray quality.
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. It is recommended that a non-ionic surfactant
be added to the spray solution at a 0.25 to 0.5% v/v ratio. 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.

APVMA Compliance Instructions for Mandatory COARSE or Larger Droplet Size Categories
Important Information
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.
In the following instructions, Section 1 is for ground application and Sections 2 and 3 are for aerial
application. 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.
SECTION 1 Instructions for Ground Application – for COARSE droplet size or larger categories
Mandatory Instructions for Ground Applications
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 category 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.
Sections 2 and 3 are not applicable to this label.

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 when wind speed is less than 3 or more than 20 kilometres per hour as measured at the
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 smaller than COARSE spray droplets according to ASAE S572 definition for standard
nozzles.
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.

Herbicide Resistance Warning GROUP B I HERBICIDE
CASPER Turf herbicide is a member of the sulfonylureas and benzoic acid groups of herbicides and has the
ALS inhibitor and disruptor of plant cell growth modes of action. For weed resistance management CASPER
is a Group B and I herbicide. Some naturally occurring weed biotypes resistant to CASPER and other Group
B and I 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 CASPER or other Group B or I 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 CASPER 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.

Integrated Pest Management
The possible effects of CASPER on integrated pest management (IPM) strategies in the turf industry have
not been studied at the proposed rates. However, based on available information, it cannot be ruled out that
CASPER may have an adverse effect on non-target beneficial turfgrass invertebrates where such IPM is
practised.

PRECAUTION
General Safety Precaution
DO NOT apply using spraying equipment carried on the back of the user.
Re-entry Period
DO NOT allow the general public to enter treated areas until the spray has dried.
DO NOT allow entry into treated areas until the spray has dried for low exposure activities such as mowing,
unless wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and elbow-length
chemical resistant gloves. Clothing must be laundered after each day’s use.
DO NOT ALLOW entry into treated areas for 14 days for high exposure activities such as hand weeding or
transplanting, unless wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and
elbow-length chemical resistant gloves. Clothing must be laundered after each day’s use.

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS
This product is 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.

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

STORAGE AND DISPOSAL
Store in the closed, original container in a dry, cool, well ventilated area out of direct sunlight. Triple or
