RESTRICTIONS
ADDITIONAL ADVICE FOR OPERATORS
• SHIRLAN may cause transient skin reaction in a small number of sensitive individuals.
• Do not come in contact with spray drift. Ensure spraying is carried out under good conditions and that the sprayer is adjusted to minimise drift.
• Do not allow contact of contaminated clothing with unprotected skin.
• Do not allow contact between contaminated sprayer parts and unprotected skin. Ensure sprayer is washed down daily.
• Wash all protective clothing (coveralls) regularly, preferably daily, when working with SHIRLAN.
• When entering crops do not allow contact of unprotected skin with treated foliage.
• People who have been sensitised by SHIRLAN should not use or have further contact with the product.
DISEASES CONTROLLED
SHIRLAN is an agricultural fungicide for the control of Foliar Blight (
Phytophthora infestans) and protection against Tuber Blight in potatoes.
BACKGROUND TO POTATO BLIGHT CONTROL
Late blight (
Phytophthora infestans) is potentially a devastating disease of potatoes. In commercial production, a season long
disease prevention policy is essential. First of all ensure that other control methods are being satisfactorily applied:
1. Prevent re-growth on potato dumps.
2. Destroy all groundkeepers.
3. Plant disease-free seed.
4. Use generous soil ridges to protect tubers.
Integrate this approach with a fungicide programme:
Early Crops
In first and second early potato crops, particularly those grown in the same locality as main crop potatoes, an adequate and full blight protection programme should be applied right up to harvesting or haulm desiccation. This will protect the early crop while helping to reduce disease risk to later crops.
Main Crops
Disease prevention programmes require regular and season-long fungicide use to limit foliar blight development. However, as an effective fungicide programme will preserve leaf area there may be more risk of infecting tubers at harvest, particularly during “heavy” blight years. Completion of the control programme should therefore include a complete haulm desiccant. Lifting of the crop should not take place for at least 10 days after
COMPLETE KILL of the haulm. Crops intended for storage should not be lifted while there is any green tissue
AT ALL on the leaves or stem bases.
Blight Risk Assessment
The risk of disease is affected by
weather conditions (during the crop life) and
crop location.
Weather Conditions – Spread of disease occurs under warm, humid conditions. Preferably use a reliable decision support system to determine what frequency of fungicide treatment is appropriate and fungicide type required.
Note: Blight forecasting has often been based on the occurrence of “Smith Periods”. A “Smith Period” is a 48 hour period in which the minimum temperature is 10°C or more and the relative humidity exceeds 90% for at least 11 hours during the first 24 hours and for at least 11 hours again during the final 24 hours. However, any period of warm, humid weather increases blight risk.
Crop Location – Locations with the highest probability of blight problems are:
• Areas of the country where extensive main crop or early production takes place e.g. East Anglia, the South West or the West.
• Areas where climatic conditions that encourage disease development occur on a frequent basis. e.g. the South West, the West and the Fens.
CROP SPECIFIC INFORMATION
Timing
1. Initial Application
SHIRLAN is a protectant fungicide and therefore the spray programme must start BEFORE blight enters the crop.
Irrespective of crop growth stage, commence spraying at the first blight warning or when local weather conditions are favourable for the disease,
whichever is the sooner. Otherwise, in the absence of weather conducive to disease development, the first application should be made just before foliage of adjacent plants begins to meet IN THE ROWS.
2. Repeat Applications
Intervals between applications of SHIRLAN MUST be reduced as blight risk increases, so that
protection of the crop can be maintained, as follows:
“Low risk” situations – applications should be made as a precautionary measure, before conditions conducive to blight development have occurred – APPLY AT 14 DAY INTERVALS
“High risk” situations – following two warm, humid days or in irrigated crops – APPLY AT 7–10 DAY INTERVALS.
“Severe risk” situations – during continued warm, humid weather and when blight is in nearby crops, potato dumps or volunteer plants – APPLY 300 ml AT 5–7 DAY INTERVALS OR 400 ml AT 7 DAY INTERVALS AS APPROPRIATE, ACCORDING TO BLIGHT WARNINGS AND DISEASE PREDICTION SYSTEMS
N.B. Potato blight fungicides may not give complete protection when the disease risk is severe. However, disease development will be delayed dramatically with a well timed spray programme.
Do not apply more than a maximum total dose of 3 litres product/ha/crop.
3. For protection against Tuber Blight
To reduce the risk of problems with tuber blight at harvest SHIRLAN should be used regularly at the recommended intervals from full canopy development to complete haulm desiccation.
Rates of Use
Apply 300–400 ml/ha of SHIRLAN at each treatment.
Crops grown for processing
Consult processor before use.
MIXING AND SPRAYING
Apply SHIRLAN in 200 to 500 litres of water per hectare. Use adequate water to ensure complete coverage of the foliage and stems, increasing the volume as haulm growth progresses, particularly in dense crops and under high or severe blight risk conditions.
Application Details
1. Application Equipment: Apply SHIRLAN through tractor-drawn or mounted, conventional hydraulic crop spraying equipment.
2. Sprayer Preparation: Ensure that the sprayer is clean and calibrated correctly, to give even application. Apply at the recommended water volumes using a MEDIUM quality spray (as defined by British Crop Protection Council guidelines).
3. Spray Pressure: at least 2 bar.
4. Mixing: Before mixing SHIRLAN, first part fill the spray tank with clean water and commence agitation. Then, shake the SHIRLAN container and add the required amount of product to the sprayer using a filling device (e.g. induction bowl, probe etc), or otherwise by direct addition to the spray tank.
Wash out empty container thoroughly and add washings to the sprayer. Preferably use an integrated pressure rinsing device, otherwise manually rinse the container three times. DO NOT RE-USE CONTAINER FOR ANY PURPOSE.
Agitate spray tank contents thoroughly whilst filling and throughout the spraying operation.
Do not leave the spray liquid in the sprayer for long periods (such as during meal breaks or overnight).
Disease Resistance
Disease control may be reduced if strains of pathogen less sensitive to SHIRLAN develop.
This product is to be used only in accordance with the recommendations and instructions given on the label provided with this pack. Use in any other circumstances is entirely at the user’s risk.

SAFETY PRECAUTIONS
(a) Operator protection
Engineering control of operator exposure must be used where reasonably practicable in addition to the following personal protective equipment:
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS), SUITABLE PROTECTIVE GLOVES AND FACE PROTECTION (FACESHIELD) when handling the concentrate.
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS) AND SUITABLE PROTECTIVE GLOVES when handling contaminated surfaces.
However engineering controls may replace personal protective equipment if a COSHH assessment shows they provide an equal or higher standard of protection.
TAKE OFF IMMEDIATELY all contaminated clothing.
WASH CONCENTRATE from skin and eyes immediately.
WASH ALL PROTECTIVE CLOTHING thoroughly after use, especially the insides of gloves.
WASH HANDS AND EXPOSED SKIN before meals and after work.
IF YOU FEEL UNWELL seek medical advice (show label where possible).
(b) Environmental protection
DO NOT ALLOW DIRECT SPRAY from horizontal boom sprayers to fall within 5 metres of the top of the bank of a static or flowing water-body, unless a Local Environmental Risk Assessment for Pesticides (LERAP) permits a narrower buffer zone, or within 1 metre of the top of a ditch which is dry at the time of application. DO NOT ALLOW DIRECT SPRAY from hand-held sprayers to fall within 1 metre of the top of the bank of a static or flowing water-body. Aim spray away from

water.
This product qualifies for inclusion within the Local Environmental Risk Assessment for Pesticides (LERAP) scheme. Before each spraying operation from a horizontal boom sprayer, either a LERAP must be carried out in accordance with PSD published guidance or the statutory buffer zone must be maintained. The results of the LERAP must be recorded and kept available for 3 years.
DO NOT CONTAMINATE SURFACE WATERS OR DITCHES with chemical or used container.
Do not clean application equipment near surface water. Avoid contamination via drains from farmyards and roads
