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. Dithianon WG is a fungicide containing dithianon for use on apples and pears. For professional use only.

APPLES and PEARS
Diseases: Scab on apples and pears
Rate: 0.75kg/ha
Critical comments: Maximum Number of applications: 12 per crop. Latest time of application: 21 days before harvest. For low water volume applications, the maximum concentration must not exceed 0.75 kg product in 200 litres of water.

Restrictions/Warnings
On variety Golden Delicious, do not use Dithianon WG after green cluster. Dithianon WG must not be mixed with lime sulphur or highly alkaline products.
Disease
Control Dithianon WG is a fungicide recommended for the control of scab on apples and pears.
Resistance
Dithianon WG contains dithianon, a dicarbonitrile fungicide with broad-spectrum, preventative properties. Dithianon is a multi-site inhibitor that acts by modification of sulfhydryl (SH) groups found in the cysteine residues of many proteins. Because of its multi-site mode of action, Dithianon WG has a low risk of resistance development and there have been no reports of resistance or reduced sensitivity to this fungicide. Ensure that Dithianon WG is used according to the label recommendations and in accordance with FRAC (Fungicide Resistance Action Group) guidelines.

Crops
Apples and pears: Dithianon WG (applied alone)
Time of application
Apply from the beginning of bud burst. On variety Golden Delicious, do not use Dithianon WG after green cluster.
Rate of application
Apply 0.75 kg of Dithianon WG in a minimum of 200 litres water/ha. Interval: 7 – 14 days. Use a 7 day interval in periods of high disease pressure. Also use a 7 day spray interval on varieties that are highly susceptible to scab infection, when carryover is high, or when crop growth is rapid. Repeat applications until danger of scab attack ceases. Water volumes should be based on the size of the trees and leaf area at application, and sufficient to ensure good coverage.
Number of applications
Apply a maximum of twelve applications per year.

Apples: application of Dithianon WG in mixture with Scala for improved control of scab
Dithianon WG is a protectant fungicide. For more robust protection during scab infection periods it is recommended to tank mix Scala with Dithianon WG. Scala will provide additional curative activity and extra protection of new growth due to its translaminar and vapour activity. If scab infection periods have already occurred prior to application, it is recommended to apply the tank-mix as soon as practical after the infection period.
Time of application
Apply from the beginning of bud burst. Do not apply Scala after the end of flowering. On variety Golden Delicious, do not use Dithianon WG after green cluster.
Rate of application
Apply 0.75 l/ha of Scala with 0.75 kg/ha Dithianon WG. Interval: 7 - 10 days. During scab infection periods apply at 7 - 10 day intervals. Use a 7 day interval during periods of high disease pressure or on varieties that are highly susceptible to scab infection. Water volumes should be based on the size of the trees and leaf area at application, and sufficient to ensure good coverage.
Number of applications
A maximum of five applications of Scala may be made per year.

Mixing and Spraying
Half fill the spray tank with clean water and start agitation. Slowly add in the required amount of product. Empty container completely and dispose of safely. Add the remainder of the water and continue agitation until spraying is complete. Apply by any low or high volume orchard sprayer.
