DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be carefully read in order to obtain safe and successful use of this product. 
GENERAL INFORMATION
AMISTROBIN contains azoxystrobin, a broad spectrum fungicide from the strobilurin group. It has systemic, translaminar and protectant properties. 
Azoxystrobin inhibits fungal respiration. Its mode of action is different from the action of other fungicidal groups. AMISTROBIN must always be used in mixture with fungicides with other modes of action. 
AMISTROBIN shows good crop safety, disease control and maintenance of green leaf area which result in significant yield benefits. 
AMISTROBIN is best used as a protective treatment or during early stages of disease establishment. In cereals, the length of disease control is generally about 4–6 weeks during the period of active stem elongation, but can be more when applied at flag leaf/ear emergence. 
AMISTROBIN is approved for application to wheat, barley, rye, triticale, oats, combining and vining peas, bulb onions, oilseed rape, outdoor asparagus, leeks, carrots, field beans, potatoes, Brussels sprouts, cabbage, cauliflower, kale (winter greens), collards (spring greens), broccoli and calabrese.

CROP SPECIFIC INFORMATION
WINTER & SPRING WHEAT
Yield response 
A yield response may be obtained with AMISTROBIN in the absence of visual disease control.
Rate of use
1.0 litre per hectare
Spray timing 
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stages of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems. When used to control the listed foliar diseases, AMISTROBIN applied at the first or second node stage of the crop can reduce the severity of Take-all infection.
Tank mixing 
AMISTROBIN must always be applied in tank mix with an appropriate partner fungicide with a different mode of action. Both products must be applied at the recommended rate.

WINTER & SPRING BARLEY, RYE AND TRITICALE
Rate of use
1.0 litre per hectare.
Spray timing
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stages of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems. For protection against ear disease apply AMISTROBIN at ear emergence. When used to control the listed foliar diseases, AMISTROBIN applied at the first or second node stage of the crop can reduce the severity of Take-all infection.
Tank mixing
AMISTROBIN must always be applied in tank mix with an appropriate partner fungicide with a different mode of action. Both products must be applied at the recommended rate.

WINTER AND SPRING OATS
Growing conditions
Apply AMISTROBIN under good growing conditions with adequate soil moisture. Avoid poor growing conditions which may give less reliable results.
Rate of use 
1.0 litre per hectare.
Spray timing
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stage of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems.
Tank mixing
AMISTORBIN must always be applied in tank mix with an appropriate partner fungicide with a different mode of action. Both products must be applied at the recommended rate.
Resistance management
Use AMISTROBIN as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action. You must not apply more than two foliar applications of Qol-containing products to any cereal crop. 
There is widespread Qol resistance occurring in Septoria tritici populations in Ireland. Failure to follow resistance management action may result in reduced levels of disease control. 
Strains of powdery mildew resistant to Qol’s are common in Ireland. 
Disease control may be reduced if strains of other pathogens less sensitive to azoxystrobin develop. 
On cereal crops, AMISTROBIN must always be used in mixture with another product, recommended for control of the same target disease that contains a fungicide from a different cross resistance group and is applied at a dose that will give robust control. 
Users should refer to current FRAC guidelines for Qol compounds.

PEAS – COMBINING AND VINING
Growing conditions
Apply AMISTROBIN under good growing conditions with adequate soil moisture. Avoid poor growing conditions which may give less reliable results. AMISTROBIN should always be used at the first sign of disease infection or when a predictive assessment shows conditions favourable for disease development. Always inspect crops to assess disease development immediately before spraying. For optimum disease control apply AMISTROBIN before infection or as soon as disease is first seen in the crop.
Rate of use
1.0 litre per hectare. 
A second treatment may be required if disease pressure remains high – especially in combining peas.
Spray timing 
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stage of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems.

PEAS FOR PROCESSING
Where a crop of peas is destined for processing, consult your processor before treating with AMISTROBIN. (One years results indicate that no taints were detected on quick frozen, canned vining or canned combining peas).
Crop safety 
AMISTROBIN shows good crop safety on combining and vining peas. Before applying ensure the crop is free from any stress caused by environmental or agronomic effects. Check wax level if necessary using a Crystal Violet test.
Resistance management 
To avoid the likelihood of resistance developing, application of AMISTROBIN should be made with due regard to current FRAC guidelines for Qol compounds. Do not make more than two applications of AMISTROBIN to crops of combining and vining peas.

BULB ONIONS, LEEKS AND CARROTS
Growing conditions
Before applying AMISTROBIN ensure the crop is free from any stress caused by environmental or agronomic effects. For optimum disease control AMISTROBIN should be used at the first sign of disease infection or preferably preventatively when a predictive assessment shows conditions favourable for disease development. Always inspect crops to assess disease development immediately before spraying.
Rate of use 
1.0 litre per hectare.
Spray timing 
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stage of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems. AMISTROBIN should be used as part of an overall spray programme with due regard to current FRAC guidelines.

Bulb Onions
For optimum downy mildew control in bulb onions a 7 to10 day spray interval should be maintained 
Applications to established downy mildew infection are unlikely to give reliable control
Processing
Where a crop is destined for processing, consult your processor before treating with AMISTROBIN
Resistance management 
Use AMISTROBIN as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action. To avoid the likelihood of resistance developing, application of AMISTROBIN should be made with due regard to current FRAC guidelines for Qol compounds. Do not apply more than a total of three applications when used in mixture with a fungicide from a different cross resistance group, as part of a programme. Do not apply more than a total of two applications if AMISTROBIN is used as a solo product.

FIELD BEANS
Timing
Before applying AMISTROBIN, ensure the crop is free from any stress caused by environmental or agronomic effects. Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stage of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems.
A second treatment may be required if disease pressure remains high
Rate of use 
1.0 litre per hectare
Resistance management 
To avoid the likelihood of resistance developing, application of AMISTROBIN should be made with due regard to current FRAC guidelines for Qol compounds. Do not make more than two applications of AMISTROBIN to crops of field beans. Use AMISTROBIN as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action

POTATOES
Timing
AMISTROBIN must be applied as either an overall and incorporated application made prior to planting or as an in-furrow application made at the time of planting. 
Where AMISTROBIN is applied as an overall and incorporated treatment, apply the product as an overall spray on the entire area to be planted. Apply as a coarse quality spray preferably through air-induction nozzles, the nozzles to be mounted 50 cm above the soil. Immediately after application AMISTROBIN should be incorporated into the soil to a depth of approximately 15 cm and then the potato crop should be planted. Planting should occur on the same day as application. 
Where AMISTROBIN is applied as an in-furrow application, it is important to direct the spray into the planting furrow and not onto the seed tuber. Application should be made using two nozzles per row – one at the front of the planting share and directed down into the furrow and the second, at the rear of the share and directed so as to spray the soil as it closes around the planted tuber
Rate of use 
For overall and incorporated application made prior to planting: 6.0 litres per hectare
OR
For in-furrow application made at planting: 3.0 litres per hectare With both methods of treatment, a maximum of one application per crop should be made
Advisory information
With in-furrow application, always target the soil and not the seed tuber in order to minimise any possible delay in emergence. Wherever possible, use properly chitted seed or cold-stored seed which has not started to sprout. Using seed which has just broken dormancy may well result in emergence delays. Using AMISTROBIN following earlier applications of imazalil, pencycuron or imazalil/pencycuron is likely to lead to a check in the speed of crop emergence. Effects are usually, but not always, outgrown.
Effects of soil type 
Do not use AMISTROBIN on high organic matter soils as the product will not be effective
Potatoes for processing
Where a crop of potatoes is destined for processing, consult processors before treating with AMISTROBIN.
Resistance management
The risk of resistance developing to AMISTROBIN in Rhizoctonia solani (Black scurf and Stem canker) is considered to be very low. The resistance risk is higher for Colletotrichum coccodes (Black dot) and to minimise this potential risk, tubers from crops treated with AMISTROBIN should not be used for seed. AMISTROBIN should only be used in potato crops, which adhere to good rotation practices. To avoid the likelihood of resistance developing to QoI compounds used to control potato late blight, application of AMISTROBIN should be made with due regard to current FRAC guidelines for QoI compounds. If an application of AMISTROBIN is made, no more than two further QoI treatments should be applied sequentially as the first sprays against blight before using an alternative product. 

BRUSSELS SPROUTS, CABBAGE, CAULIFLOWER, KALE (WINTER GREENS), COLLARDS (SPRING GREENS), BROCCOLI AND CALABRESE
Timing
Before applying AMISTROBIN, ensure the crop is free from any stress caused by environmental or agronomic effects. Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stage of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems. 
A second treatment may be required if disease pressure remains high. A minimum interval of 12 days must be observed between applications to brassicae.
Rate of use
1.0 litre per hectare
Resistance management
To avoid the likelihood of resistance developing, application of AMISTROBIN should be made with due regard to current FRAC guidelines for Qol compounds. Do not apply more than a total of two applications of AMISTAR to any brassica crop.

WINTER AND SPRING OILSEED RAPE
Timing
Before applying AMISTROBIN, ensure the crop is free from any stress caused by environmental or agronomic effects. Best results will be achieved from applications made as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems. A second treatment may be required if disease pressure remains high. Sclerotinia – AMISTROBIN should be applied as a protectant spray during flowering. The optimum timing is early flowering to mid flowering (GS60–GS65). Alternaria – Apply AMISTROBIN as a protectant spray before disease becomes established.
Rate of use
1.0 litre per hectare
Resistance management 
To avoid the likelihood of resistance developing, application of AMISTROBIN should be made with due regard to current FRAC guidelines for Qol compounds. Do not make more than two applications of AMISTROBIN to crops of oilseed rape. Use AMISTROBIN as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action

ASPARAGUS (OUTDOOR) 
Timing
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made in the earliest stages of disease development or as a protectant treatment following a disease risk assessment or the use of appropriate decision support systems
Earliest time of application: After commercial cutting. AMISTROBIN may only be applied after the harvest season (i.e. after commercial cutting). Where a new ‘bed’ is established, do not treat within 3 weeks of transplanting out the crowns.
The application interval between subsequent treatments should be 8 to 12 days.
Latest time of application: Until the end of September or before crop senescence, whichever is sooner.
AMISTROBIN shows good crop safety on asparagus. Before applying ensure the crop is free from any stress caused by environmental or agronomic effects.
Rate of use
1.0 litre per hectare.
Resistance management
 AMISTROBIN contains azoxystrobin a member of the Qol cross resistance group. AMISTAR should be used preventatively and should not be relied on for its curative potential. Disease control may be reduced if strains of pathogens less sensitive to azoxystrobin develop. To avoid the likelihood of resistance developing, application of AMISTROBIN should be made with due regard to current FRAC guidelines for Qol compounds. Use AMISTROBIN in mixture with a fungicide from a different cross resistance group, as part of a programme. Do not apply more than a total of two applications of AMISTAR. 

APPLICATION 
Preparation of the sprayer and mixing
Ensure that the sprayer is clean and correctly set to give an even application at the required volume. Half-fill the spray tank with clean water and start agitation. Shake the container and add the required amount of AMISTROBIN to the sprayer using a filling device (e.g. induction bowl or closed transfer unit) or by direct addition to the sprayer tank
Wash out containers thoroughly, preferably using an integrated pressure rinsing device, or manually rinse three times. Add washings to the sprayer at the time of filling. Complete filling to the required volume and continue to agitate throughout the spraying operation.
Do not leave the spray liquid in the sprayer for long periods (such as during meal breaks or overnight).
Volume of water and spraying
Apply using a medium quality spray at a pressure of at least 2 bar. Apply through conventional crop spraying equipment.
Cereals, peas, bulb onions, leeks, carrots, field beans and oilseed rape
Apply in at least 200 litres of water per hectare. In dense crops, increase the water volume to 250–300 litres per hectare to improve coverage.
Asparagus
For conventional tractor mounted crop spraying equipment, apply in at least 600 litres of water per hectare using a medium quality spray at a pressure of at least 2 bar.
For hand-held spraying equipment, apply in at least 200 litres of water per hectare.
Potatoes
For overall and incorporated application, use 200–400 litres of water per hectare. Apply only as a medium/coarse spray using either Pre-Orifice or Air-Induction nozzles. The type of nozzle used for soil acting herbicides should be suitable. During application, care should be taken to avoid drift onto any adjacent crops
For in-furrow application, use between 50–150 litres of water per hectare. Apply using specialist in-furrow application equipment.
