Although this remedy has been extensively tested under a large variety of conditions the registration
holder does not warrant that it will be efficacious under all conditions because the action and effect thereof
may be affected by factors such as abnormal soil, growth medium, climatic and storage conditions, quality
of dilution water, incompatibility with other substances not indicated on the label and the occurrence of
resistance of disease against the remedy concerned as well as by the method time and accuracy of
application. The registration holder, furthermore does not accept responsibility for damage to crops,
vegetation, the environment or harm to man or animal or for lack of performance of the remedy concerned
due to failure of the user to follow the label instructions or to the occurrence of conditions which could not
have been foreseen in terms of the registration. Consult the supplier in the event of any uncertainty.

• Destroy empty containers and never use for any other purpose.
• Prevent contamination of food, feed, drinking water and eating utensils.
• Clean applicator after use by rinsing thoroughly with clean water. Prevent wash water
contaminating other areas.
RESISTANCE WARNING:
For resistance management, KRESO 50 WG is a group code 11 fungicide. Any fungus
population may contain individuals naturally resistant to KRESO 50 WG and other group code
KRESO 50 WG/02/03/2011.1
2
11 fungicide. The resistant individuals can eventually dominate the fungus population if these
fungicides are used repeatedly. These resistant fungi may not be controlled by KRESO 50 WG
or any other group code 11 fungicide.
To delay fungicide resistance:
• Avoid exclusive repeated use of fungicide from the same fungicide group code. Alternate
or tank mix with products form different fungicide group codes.
• For tank mixing or alternation with products in fungicide group code M, refer to applicable
individual product labels.
• Integrate other control methods (chemical, cultural, biological) into disease control
programmes.
For specific information on resistance management contact the registration holder of this
product.
DIRECTIONS FOR USE:
Use only as directed.
Compatibility:
• KRESO 50 WG is compatible with CungFu 538 SC (copper hydroxide 538 g/ℓ, Reg. no.:
L7526, Act 36 of 1947), COPRO FLOW S (basic copper sulphate 320 g/ℓ, Reg. no.: L 8118,
Act 36 of 1947) and most commonly used modern insecticides.
Mixing Instructions:
• Pre-mix the required amount of copper in at least 10 litres of water and add it to the spray
tank, half filled with clean water.
• Thereafter, measure the required volume of KRESO 50 WG, pre-mix in at least 10 litres of
water before also adding to the spray tank.
• For citrus only, finally add the mineral oil (e.g. HYPER MEDIUM OIL, Reg. no. L 7355, Act 36
of 1947), to the mixture.
• Fill the spray tank with water to the final volume required, while maintaining agitation to
ensure thorough mixing of the spray mixture before spraying commences.
• Maintain agitation while spraying.
• Prepared spray mixture must not be left in the spray tank for any length of time, e.g.
overnight.
Rain-fastness:
• KRESO 50 WG is not easily washed off by rain after it has dried on the crop.
• Rainfall up to 20 mm, one day after application, will normally not negatively affect the
fungicidal activity of the product.
Application:
• With the introduction of strobilurin fungicides, such as KRESO 50 WG, a new application
concept, the “block” concept, is proposed.
• On this label, reference to a “block” means a series of 2 to 3 consecutive treatments with a
strobilurin fungicide.
• In order to optimize the fungicidal activity of the product, it is very important to apply
KRESO 50 WG according to the anti-resistance strategy rules as given below.
General Anti-resistance Strategy Rules:
• Apply KRESO 50 WG in principle on a preventive basis.
• The total number of KRESO 50 WG and other strobilurin applications should (except in the
case of citrus) not constitute more than 40 % of the total number of fungicide applications
made to the crop in one season.
• Use other registered fungicides, with a mode of action that differs from strobilurins, for the
remainder of the spray programme.
KRESO 50 WG/02/03/2011.1
3
• The last fungicide application of the season should (except in the case of citrus) not be
carried out with a strobilurin fungicide.
APPLES AND PEARS:
• KRESO 50 WG can be applied on a preventive (powdery mildew and scab) and a curative
(scab) basis.
• Start KRESO 50 WG applications as early in the season as possible.
• Apply KRESO 50 WG in a “block” of 2 to 3 consecutive treatments.
• Within a “block”, KRESO 50 WG can be applied preventively or curatively as dictated by the
occurrence of infection periods.
• Increase the dosage rate as recommended for curative treatments only after infection periods
(within 2 days after the onset of the infection period).
• Do not apply more than 3 sprays with KRESO 50 WG or any other strobilurin per season.
High Volume Applications:
The water volume to be applied per hectare should be calculated according to the Tree-RowVolume (TRV) formula described by Unrath (Deciduous Fruit Grower No. 1986):
Litre/ha= Tree height x Tree depth x 937
Row Width
The above formula indicates the required volume of water for high volume (HV) applications
when the trees are in full leaf. Based on the above formula the following water volumes are
recommended for the various growth stages:
Growth Stage:
% HV water requirement/ha:
Greentip – 30% of full blossom:
60 %
Full blossom – middle November:
80 %
From beginning December:
100 %
Low Volume Applications:
When low volume sprays are applied the dosage rate of KRESO 50 WG per 100 litres water
must be increased in order to maintain the same amount of fungicide applied per hectare as in
the case of a high volume application. Use above formula and growth stage table to calculate
the required amount of KRESO 50 WG per hectare.
CITRUS (EXCLUDING LEMONS):
In order to optimize the fungicidal activity of the product and ensure sustainable use of
strobilurins, it is very important to apply KRESO 50 WG in a programme with basic copper
sulphate or copper hydroxide according to a resistance management programme. To maintain
a high level of control, correct timing of applications is critically important.
• Apply KRESO 50 WG as part of a programme. The first application being copper, starting at
fruit set (100 % petal drop), at the registered rate, followed by two KRESO 50 WG
applications, as recommended in the table below. A final spray of at least one copper
application, as recommended, must complete the spray programme.
• Do not apply KRESO 50 WG to lemons or old, neglected citrus trees, as they are extremely
prone to fungicidal resistance.
• KRESO 50 WG should always be applied as a preventive treatment with limited curative
abilities (maximum 3 days).
• Refer to the respective copper and light narrow mineral oil labels for directions regarding their
applications.
• Apply as a medium or full cover spray.
GRAPES:
• Start KRESO 50 WG applications as early in the season as possible.
KRESO 50 WG/02/03/2011.1

• Apply preventively before an infection period occurs.
• In a spray programme, apply KRESO 50 WG in a “block” of maximum 3 applications
containing FRAC fungicide group code 11 fungicides, per season.
• Alternate with products in the spray programme with products from different group codes.
Table grapes:
KRESO 50 WG may be applied as a high or a low volume application. The dosage rate per 100
litres as recommended in the “Application Table” below, is meant for a high volume application.
In case of low volume applications the dosage rate per 100 litres should be increased in order to
apply the same amount of product per hectare as in the case of the high volume application.
Wine grapes:
KRESO 50 WG may be applied as indicated for table grapes. It is also possible to lengthen the
spray intervals while spraying at increased rates as indicated in the “Application Table”.
High Volume Applications for Table and Wine Grapes:
Spray to the point of run-off ensuring even coverage.
depending on the leaf area present:
Growth Stage
Apply the following water volumes
Water volume in ℓ/ha
Shoots 2 to 5cm long up to before blossom:
350 – 500 ℓ/ha
Blossom to pea-size of the berries:
500 –1000 ℓ/ha
Berries at pea-size up to harvest:
1000 – 1500 ℓ/ha
Low Volume Applications:
• The amount of product needed per hectare should be calculated from the corresponding high
volume application.
• The concentration of the spray mixture should not exceed four times (4x) the concentration
as recommended for the high volume application.
• Apply in at least 250 litres water per hectare.
• Ensure even coverage.
ROSES:
• KRESO 50 WG must be applied on a preventive basis.
• Start KRESO 50 WG applications as early in the season as possible.
• Apply KRESO 50 WG in up to two “blocks” of 2 to 3 consecutive sprays each.
• Do not apply more than 3 consecutive sprays with KRESO 50 WG or any other strobilurin per
“block”.
• Separate the first and second KRESO 50 WG “blocks” by spraying at least twice with
registered fungicides with modes of action which differ from the mode of action of strobilurins,
e.g. REPUTE (Reg. no. L 6824, Act 36 of 1947).
• Do not apply more than 6 applications with KRESO 50 WG or any other strobilurin per
season.
• Apply KRESO 50 WG as a medium to high volume application in 750 to 1500 litres water per
hectare.
• Ensure even coverage of the crop.
GENERAL:
• KRESO 50 WG is characterized by a special mode of transport and uptake action with long
lasting effect and translaminar activity.
• KRESO 50 WG can also be sprayed once infection has occurred in the case of scab on
apples and pears (up to 72 hours after the onset of infection).
• KRESO 50 WG is not harmful to bees.

DIRECTIONS FOR USE:
Curative:
Use KRESO 50 WG (only after the occurrence of infection
periods) in addition to a preventive program with other
registered products. Apply within 2 days after infection has
occurred (maximum 72 hours) as a high volume spray.
Commence applications at the pink stage and apply in a
preventive program at 7 to 14 day intervals.
Applications as recommended for scab control. Will also
control powdery mildew.
Commence applications at the onset of the disease (less
than 1% infection). Apply in a preventive program at 14 day
intervals in at least 500 litres water per hectare.
Ensure good coverage of all plant parts.
Do not apply more than ⅓ of the total number of
applications per season with KRESO 50 WG or any other
Group Code 11 fungicides (see “RESISTANCE WARNING”
above).
Apply as full cover spray with the first appearance of mildew
symptoms and repeat at 7 to 10 day intervals. Use the
shorter intervals in cases where climatic conditions are
favourable for development of powdery mildew. Do not
apply more than three consecutive treatments within one
‘block’. Alternate treatments in ‘blocks’ with at least two
applications of alternative registered products, e.g.
REPUTE. Refer to “Applications” above for explanation of
the “block” concept.
First application of programme:
Refer to comments under “CITRUS” above. Apply one
copper application at fruit set (100 % petal drop). Refer to
the relevant copper label for further details.
Second and Third application of programme:
Apply KRESO 50 WG 21 to 24 days after the first copper
application, as a preventive treatment.
Ensure good
coverage of all fruit with a medium to full cover spray.
Apply a second KRESO 50 WG application 6 weeks later.
Final application of programme:
Apply copper 6 weeks after the second KRESO 50 WG
application.
