GENERAL INFORMATION


VERTAZA 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. It should always be used in mixture with fungicides with other modes of action.
VERTAZA shows good crop safety, disease control and maintenance of green leaf area which result in significant yield benefits.
VERTAZA is best used as a protective treatment or during early stages of disease establishment. In cereals, the length of disease control is generally about four to six weeks during the period of active stem elongation, but can be more when applied at flag leaf/ear emergence.
VERTAZA is approved for application to wheat, barley, oats, rye, triticale, combining peas, fresh peas (vining peas, garden pea, mange tout, sugar snaps), fresh beans (broad beans, green beans), field beans, lupins, bulb onions, garlic, shallots, leeks, carrots, asparagus, potatoes, oilseed rape, cabbage, cauliflower, Brussels sprouts, kale (winter greens), collard (spring greens), broccoli, calabrese, outdoor and protected crops of strawberry, outdoor and protected crops of lettuce, endive (including frisee, escarole), chicory (radicchio).

CROP SPECIFIC INFORMATION
VERTAZA is approved for application to wheat, barley, oats, rye, triticale, combining peas, fresh peas (vining peas, garden pea, mange tout, sugar snaps), fresh beans (broad beans, green beans), field beans, bulb onions, garlic, shallots, leeks, carrots, asparagus, potatoes, oilseed rape, cabbage, cauliflower, Brussels sprouts, kale (winter greens), collard (spring greens), broccoli, calabrese, outdoor and protected crops of strawberry, outdoor and protected crops of lettuce, endive (including frisee, escarole), chicory (radicchio.

WINTER & SPRING WHEAT, WINTER AND SPRING BARLEY, WINTER AND SPRING OATS, RYE &
TRITICALE
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.
Winter and spring wheat, rye and triticale can be treated from BBCH 30 -69.
Winter and Spring barley and winter and spring oats can be treated from BBCH 30-59.
For protection against ear disease (Cladosporium and Alternaria) apply VERTAZA at ear emergence.
When used to control the listed foliar diseases, VERTAZA applied at the first or second node stage of the crop can reduce the severity of Take-all infection.

Rate Of Use
1.0 litre per hectare.
The maximim number of applications to any cereal crop is two per crop

Tank Mixing
On cereal crops, VERTAZA 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.

Resistance Management
Use VERTAZA 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.
Disease control may be reduced if strains of other pathogens less sensitive to azoxystrobin develop.
On cereal crops, VERTAZA 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 FRAG-UK guidelines for Qol compounds.
PEAS (COMBINING AND FRESH), GREEN BEANS, BROAD BEAN, LUPIN

Timing
VERTAZA should always be used at the first sign of disease infection or when a predictive assessment shows conditions favourable for disease development from BBCH 17-72. For optimum disease control apply VERTAZA before infection or as soon as disease is first seen in the crop. 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.

Rate Of Use
1.0 litre per hectare.
A second treatment may be required if disease pressure remains high – especially in combining peas.
A minimum interval of 14 days must be observed between applications.

Peas For Processing
Where a crop of peas is destined for processing, consult your processor before treating with VERTAZA. (One year’s results indicate that no taints were detected on quick frozen, canned, vining or canned combining peas).

Crop Safety
VERTAZA shows good crop safety on combining peas and fresh peas. Before applying ensure the crop is free from any stress caused by environment or agronomic effects. Check wax level if necessary using the Crystal Violet test.

Resistance Management
To avoid the likelihood of resistance developing, application of VERTAZA should be made with due regard to current FRAG-UK guidelines for Qol compounds. Do not make more than two applications of VERTAZA.

FIELD BEAN
Timing
Before applying VERTAZA, 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 from BBCH 60-69 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 21 days must be observed between applications.

Rate Of Use
1 litre per hectare

Resistance Management
To avoid the likelihood of resistance developing, application of VERTAZA should be made with due regard to current FRAG-UK guidelines for Qol compounds. Do not make more than two applications of VERTAZA to crops of field beans. Use VERTAZA 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.

BULB ONION, GARLIC, SHALLOT, LEEK AND CARROT
Timing
Before applying VERTAZA, ensure the crop is free from any stress caused by environmental or agronomic effects. For optimum disease control VERTAZA 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. 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.
Bulb onions, garlic and shallots can be treated from BBCH 14-48
Leeks can be treated from BBCH 16 – 48
Carrots can be treated from BBCH 16 - 49

Rate Of Use
1.0 litre per hectare.

Bulb onion
• For optimum downy mildew control in bulb onions, garlic and shallot 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 VERTAZA
