For use only as a horticultural fungicide for the control of leaf scab in apples and grey mould in outdoor strawberries and the moderate control of grey mould in protected strawberries.

A suspension concentrate containing 400 g/l (37.4% w/w) pyrimethanil.

DIRECTIONS FOR USE IMPORTANT:
This information is approved as part of the product label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

APPLE
Diseases: Leaf scab (Venturia inaequalis)
Rate: 1.125/ha
Critical comments: Maximum number of treatments: 4 per year. Latest time of application: 56 days before harvest.

STRAWBERRIES
Diseases: Leaf scab (Venturia inaequalis), Grey mould (Botrytis cinerea).
Rate: 2l/ha
Critical comments: Maximum number of treatments: 2 per crop. Latest time of application: Three days before harvest.

Restrictions/Warnings
Taint tests have shown that Scala does not taint apples, but growers should consult processors before use on strawberries. For use by tractor mounted/trailed and handheld broadcast air-assisted sprayers, tractor mounted boom sprayers and knapsack sprayers. For professional use only.

Resistance
Scala contains pyrimethanil, an anilinopyrimidine (AP) fungicide. Scala should only be used as a protectant spray. To prevent less-sensitive strains of Botrytis and Venturia from developing, Scala should be used in a programme, alternating or mixing with products of different modes of action. Application should be made in accordance FRAC Guidelines. In strawberries, where two Botrytis treatments are made per season, a maximum of one application of an AP containing product is recommended; in situations where up to six Botrytis treatments are made per season, a maximum of two applications of AP-containing products are recommended. In apples, against Venturia, a maximum of four AP containing products is recommended per season. In locations where AP insensitive strains of Venturia have been reported, Scala should be used in mixture with effective scab fungicides of differing modes of action (e.g. Dithianon Flowable).

Crops
Apples
All varieties may be treated. Time of application For the control of leaf scab, apply Scala as part of a protectant fungicide programme commencing at the start of bud burst. Depending on disease pressure, treat at intervals of 10 − 14 days, using a maximum of four applications of Scala per year. A minimum of 56 days must elapse between the last spray of Scala and harvest. Rate of application Apply 1.125 litres Scala in 500 − 1500 litres of water per hectare. Spray to achieve thorough and even cover of foliage but not to the point of run-off. Qualified recommendation A minimum water volume of 180 l/ha may be used, although the efficacy of reduced volume applications has not been evaluated.

Strawberries (outdoor)
Time of application For the control of grey mould, apply Scala as part of a fungicide programme. Commence treatment at the white bud stage to achieve maximum protection of the flowers. Depending on disease pressure, treat at intervals of 7-10 days, using a maximum of two applications of Scala per crop. A minimum of three days must elapse between the last spray of Scala and harvest. Rate of application Apply 2.0 litres Scala in 1000- 2000 litres of water per hectare. It is important to achieve accurate and complete coverage of the plants for effective protection of the crop. When using a knapsack sprayer with a 20 L tank, a maximum of 40 mls of Scala can be added to apply an equivalent of 2 L/ha over 200 square meters (10m x 20m) of crop.

Strawberries (protected)
Time of application For the moderate control of grey mould, apply Scala as part of a fungicide programme. Commence treatment at the white bud stage to achieve maximum protection of the flowers. Depending on disease pressure, treat at intervals of 7-10 days, using a maximum of two applications of Scala per crop. A minimum of three days must elapse between the last spray of Scala and harvest. Rate of application Apply 2.0 litres Scala in 400-1000 litres of water per hectare. It is important to achieve accurate and complete coverage of the plants for effective protection of the crop. When using a knapsack sprayer with a 20 L tank, a maximum of 100 mls of Scala can be added to apply an equivalent of 2 L/ha over 500 square meters (10m x 50m) of crop.

Integrated pest management
Limited evidence suggests that Scala has a negligible effect on hoverflies and lacewings and indicates some margin of safety to Typhlodromus pyri.

Mixing and Spraying
Half fill the sprayer tank with clean water and start agitation. Slowly add in the required amount of product. Rinse empty containers and add rinsings to the spray tank. Add the remainder of the water and continue agitation until spraying complete. Complete filling to the final volume. Spray immediately after mixing and maintain agitation until the spray tank is empty. Wash out the sprayer thoroughly with water and liquid detergent immediately after use. Finally wash out with water and drain.
