1. WARNINGS
• Handle with care.
• Poisonous if swallowed, inhaled or absorbed through the skin
• May cause skin and eye irritation
• Store in a cool place.
• Store away from sun and damp, in original tightly closed containers
in a well-ventilated place.
• Store away from food and feed, under lock and key.
• Keep out of reach of children, uninformed persons and animals.
• Avoid storage above 35 °C.
• Avoid spraying under cold conditions.
• Do not apply CASPER or mixtures by aerial application.
• Re-entry: Do not enter treated area until spray deposit has dried
unless wearing protective clothing.

2. PRECAUTIONS
• Do not inhale the spray mist.
• Avoid skin contact.
• Wash with soap and water after use.
• Wash contaminated clothing after use.
• Do not eat, drink or smoke while mixing or applying the product or
before washing hands and face.
• Avoid drift or spray onto other crops, grazing, rivers, dams and
areas not under treatment.
• Clean applicator after use. Ensure that all traces of CASPER are
removed. (Read sprayer cleanup). Clean applicator with a household ammonia solution (1 %) before using with other herbicides.
Allow solution to stand for several hours (preferably overnight).
• Dispose of rinsate where it will not contaminate crops, grazing, rivers, dams and boreholes.
• Prevent contamination of food, feed, drinking water and eating
utensils.
• Spray equipment should not be used for applying chemicals other
than herbicides.
• Destroy empty container and do not use it for any other purpose.
3. RESISTANCE MANAGEMENT
For resistance management, CASPER belongs both to the group
code 2 and 4 herbicides. Any weed population may contain individuals naturally resistant to CASPER and other group code 2 or group
4 herbicides. The resistant individuals can eventually dominate the
weed population if these herbicides are used repeatedly and exclusively in programs. These resistant weeds may not be controlled
by CASPER or any other group code 2 herbicides or group code 4
herbicides.
To delay herbicides resistance:
• Avoid exclusive repeated use of herbicides from the same herbicide group code. Alternate or tank mix with products from different herbicide group codes.
• Integrate other control methods (chemical, cultural, biological) into
weed control programs.
For specific information on resistance management contact the
registration holder of this product.
4. USE RESTRICTIONS
• Do not apply CASPER to crops that are stressed by severe weather conditions, drought, water logging, disease or insect damage.
• Yellowing of the funnel leaves and slight stunting may occur if
cool, wet weather conditions prevail after application. Plants
will however, outgrow these symptoms as they are of a cosmetic
nature only, and will have no effect on yield.
• Do not apply CASPER together with organophosphate insecticides.
• CASPER should not be applied if the insecticide COUNTER® (terbuphos) was applied at planting since this will increase the likelihood of injury.
• If other organophosphate insecticides are used at planting,
CASPER can only be applied a minimum of 20 days later.
• CASPER may lead to possible damage if applied to soils with pH
5 6
(H2O) of 7 and more, followed by heavy rain and/or cold shortly
after application.
• Do not apply CASPER to inbred parent plants or experimental or
newly released cultivars without first referring to the manufacturer
or seed supplier.
• CASPER is recommended for use on soil with more than 20 %
clay.
• To prevent damage, do not permit drift, vapour or spray mist to
come into contact with sensitive broadleaf crops, fruit or ornamentals. Apply the product strictly in accordance with the application
directions.
• See 4.1 below regarding recropping intervals.
• The efficacy of CASPER may be influenced by the quality of application water. Ammonium sulphate should be added at 1 ℓ /100 ℓ
water in hard water (Ca2+ + Mg2+ >150 dpm).
• The application water in which CASPER is tank mixed should
never be allowed to be below a pH of 6. The solubility of prosulfuron increases more than 100 times at pH 7 versus at a pH of 5.
The ideal pH for application water is 6.5. Do not add surfactants,
acidifiers or buffers which reduce the pH below 6 when applying
CASPER.
• Use clean water for application purposes.
• CASPER contains dicamba and can cause serious damage
to neighbouring broadleaf crops. Leave a minimal buffer zone
between the treated areas and sensitive crops as listed on following table:
Wind speed and direction at the time of application, determines the distance which must separate the closest edge of
the area to be sprayed from susceptible crops.

4.1 MINIMUM RECROPPING INTERVALS AND CROP ROTATION
GUIDELINES
To avoid injury to subsequent crops, the following recropping intervals should be observed.
7 8
Crop Recropping interval
Soybean
Sunflower
Cowpeas
5 months
All other crops 24 months
The minimum recropping interval is the time between the last application of CASPER and the anticipated date of planting of a subsequent crop.
To ensure a maximum safety margin to sensitive rotational crops, it
is recommended ploughing the fields before re-cropping.
All dicot crops are sensitive to prosulfuron. Minimal re-cropping
intervals can vary widely, depending on 3 factors:
a) amount of herbicide reaching the soil;
b) the speed of soil dissipation between application and planting
of the succeeding crop and
c) sensitivity of the succeeding crop to the soil residues
Under conditions with frequent drought, high pH or low biological
activity in the soil the intervals may have to extend.
Warning: Possible increased efficacy, phytotoxicity and residual
action
• Increasing the soil pH levels above 7 could produce conditions for
increased efficacy and reduced selectivity. This increased pH may
also result in increased soil residual action by certain herbicides
influencing the choice of following crops especially under irrigation.
• In situations where pH adjustments has been done, take care
when sulphonyl urea herbicides, triazolopyrimidine sulfonanilide
herbicides and imidazolinone herbicides, which are all sensitive to
soil pH fluctuations, have been used or are about to be used.
Contact your local SYNGENTA representative to discuss crop rotation and crop protection programmes to follow before embarking
on any pH adjustment programme
5. DIRECTIONS FOR USE
Use only as directed
General information
• Poor residual activity may be expected under dry soil conditions,
especially on late germinating or large seeded weeds, due to
reduced availability for uptake of CASPER in the soil solution.
• CASPER rapidly inhibits growth of susceptible weeds. However,
visible symptoms of dying weeds may not be noticeable for 1 to
3 weeks after application, depending on growing conditions and
weed susceptibility.
• Rainfall of 10mm and above occurring within 6 hours after a
CASPER application may reduce weed control.

5.1 COMPATIBILITY
The compatibility of CASPER with other products may be influenced
by the formulation of the products involved as well as the quality
of the water. Since the formulation of other products may change
without the knowledge of Syngenta and the quality of water may
vary from farm to farm, a physical compatibility test should always
be carried out prior to application.
CASPER is only compatible with COMPLEMENT SUPER.
CASPER should not be applied in mixtures with other herbicides,
fungicides, insecticides, fertilisers or any other chemicals not recommended on the label.
5.2 MIXING INSTRUCTIONS
CASPER is a water dispersible granular formulation, which mixes
easily with water, provided the following mixing procedures are
observed:
• Quarter to half fill the spray tank with water. Commence agitation. Add the appropriate amount of surfactant. Add the required
quantity of CASPER directly to the tank without prior creaming.
Continue agitation while topping up the tank with water and while
spraying.
• Use CASPER spray preparations within 24 hours as the effectiveness may be reduced due to product degradation. Thoroughly
agitate before re-using.
• If CASPER is tank mixed with other herbicides, insecticides and
fungicides, the CASPER must be well mixed and in suspension
before the other compounds are added.
5.3 APPLICATION TECHNIQUES
5.3.1 Ground Application
CASPER may be applied with any medium or high volume sprayer
properly calibrated and which is equipped with an efficient agitation
mechanism and which is capable of adequate coverage and even
distribution. Best results are obtained using flat fan-type spray nozzles and applying a minimum spray volume of 200 – 400 ℓ water/ha.

6. SPRAYER CLEANUP
To avoid injury to subsequent crops other than barley and wheat,
immediately after spraying thoroughly remove all traces of CASPER
from the mixing and spray equipment as follows:
• Drain spray system completely. While agitating, thoroughly rinse
spray tank with clean water and spray out the rinsate through the
nozzles. Drain system again.
• Refill spray tank with clean water to 15 – 20% of the tank volume,
thoroughly rinsing all inside tank surfaces.
• Add 1 ℓ sodium hypochlorite (5.2 %) per 200 ℓ water while agitating. Rinse nozzles with rinsate for approximately 1 minute. Let
remaining rinsate circulate in the spraying system for a minimum of
5 – 10 minutes.
• Completely spray out rinsate through the nozzles and dispose of
it where it will not contaminate crops, pastures, rivers, dams and
boreholes.
• To remove traces of the tank cleaner, flush the tank thoroughly
with clean water, rinsing all inside tank surfaces. Spray out the
remaining rinsate through the nozzles and drain system.

Quarantine period (days): 14 days for silage maize
