DIRECTIONS FOR USE
All instructions within this section must be read carefully in order to obtain safe and successful use of this product. 1. Restrictions/Warnings Taint tests have shown that Scala does not taint apples, but growers should consult processors before use on strawberries.
Disease Control
Scala is a protectant fungicide for the control of diseases in apples and strawberries, as summarised below.
APPLES
Disease:Leaf scab (Venturia inaequalis)
Rate:Apply 1.125 litres Scala in 500−1500 litres of water per hectare.
Critical Comments:C
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.
Qualified recommendation
A minimum water volume of 180 l/ha may be used, although the effectiveness and crop safety of reduced volume applications is based on limited data.
OUTDOOR STRAWBERRIES
Disease:Grey mould (Botrytis cinerea)
Rate:Apply 2.0 litres Scala in 1000−2000 litres of water per hectare.
Critical Comments:C
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 year. A minimum of three days must elapse between the last spray of Scala and harvest.
PROTECTED STRAWBERRIES
Disease:Grey mould (Botrytis cinerea)
Rate:Apply 2.0 litres Scala in 400−1000 litres of water per hectare
Critical Comments:MC
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 year. A minimum of three days must elapse between the last spray of Scala and harvest.
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. 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.
