GENERAL INSTRUCTIONS SWITCH is a water dispersible granule prepack mixture of cyprodinil and fludioxonil. Cyprodinil is systemic compound that is taken up into the cuticle and waxy layers of leaves and fruit. From there it is distributed and penetrates into other parts of the plant. Fludioxonil is the residual component of the mixture and stays mainly on the leaf and fruit surfaces.

Application Ground Application Only: Ensure thorough coverage of foliage and fruit (or bunches) using equipment delivering a MEDIUM spray quality (except for vineyard and orchard airblast sprayers).

Dilute Spraying Use a sprayer designed to apply high volumes of water up to the point of runoff and matched to the crop being sprayed. Set up and operate the sprayer to achieve even coverage throughout the crop canopy. Apply sufficient water to cover the crop to the point of runoff. Avoid excessive runoff. The required water volume may be determined by applying different test volumes, using different settings on the sprayer, from industry guidelines or expert advice. Add the amount of product specified in the Directions for Use table for each 100 L of water. Spray to the point of runoff. The required dilute spray volume will change, and the sprayer set up and operation may also need to be changed, as the crop grows.

Concentrate Spraying Use a sprayer designed and set up for concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of runoff) and matched to the crop being sprayed. Set up and operate the sprayer to achieve even coverage throughout the crop canopy using your chosen water volume. Determine an appropriate dilute spray volume (see Dilute Spraying) for the crop canopy. This is needed to calculate the concentrate mixing rate. The mixing rate for concentrate spraying can then be calculated in the following way: Example Only

  1. Dilute spray volume as determined above: for example, 1000 L/ha
  2. Your chosen concentrate spray volume: for example, 400 L/ha
  3. The concentration factor in this example is: 2.5 X (ie 1000 L ÷ 400 L = 2.5)
  4. If the dilute label rate is 80 g/100 L, then the concentrate rate becomes 2.5 x 80, that is 200 g/100 L of concentrate spray.

The chosen spray volume, amount of product per 100 L of water, and the sprayer set up and operation may need to be changed as the crop grows. For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training, and follow industry Best Practices.

Mixing SWITCH is a water dispersible granule (WG) fungicide that mixes readily with water. Partly fill the spray tank with water. Start the agitation and add the correct amount of product to the spray tank with the agitation system running. Continue agitation while topping up the spray tank with water. Add a non-ionic surfactant at registered rates (where required) at the completion of filling of the spray tank. Continue agitation while spraying.

Tank Mixing: When mixing SWITCH and other water dispersible granule (WG) or wettable powder (WP) formulations, ensure they are added and mixed well prior to adding emulsifiable concentrate (EC) or suspension concentrate (SC) products. Wettable powder (WP) formulations should be pre-mixed separately and then added to the spray tank.

COMPATIBILITY SWITCH is compatible with Bugmaster* Flowable, Delfin* WG, Dithane*, Kocide*, Lorsban* 500 W, Polyram DF, RIDOMIL® GOLD PLUS, Sanmite*, THIOVIT® JET, and TOPAS®. Mixtures with more than one of the above are not recommended. As formulations of other manufacturer’s products are beyond the control of Syngenta, all mixtures should be tested prior to mixing commercial quantities. SWITCH may not be compatible with BRAVO®.

Fungicide Resistance Warning GROUP 9 12 FUNGICIDE SWITCH Fungicide is a combination of an anilinopyrimidine and a phenylpyrrole fungicide. For fungicide resistance management, SWITCH is both a Group 9 and a Group 12 fungicide. Some naturally occurring individual fungi resistant to SWITCH and other Group 9 and Group 12 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungi population if these fungicides are used repeatedly. These resistant fungi will not be controlled by this product or other Group 9 and Group 12 fungicides, thus resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use Syngenta Australia Pty Ltd accepts no liability for any losses that may result from the failure of this product to control resistant fungi.

RESISTANCE MANAGEMENT In order to minimise the likelihood of the development of fungicide resistance, it is recommended that SWITCH be used in a program incorporating all available forms of crop protection. SWITCH should be applied as part of a protective spray program using fungicides from different mode of action group/s. Alternating or mixing fungicides with different modes of actions is a recognised disease resistance management strategy. DO NOT wait until disease levels have built up before commencing applications as this reduces the effectiveness of control and increases the risk of resistance development. Disease control may be reduced if strains of pathogens less sensitive to SWITCH Fungicide develop. SWITCH Fungicide should be applied as specified in the Directions for Use in association with the following CropLife Fungicide Resistance Management Strategies: Grapes: If three or fewer bunch rot sprays are applied in a season, use only one spray containing a Group 9 fungicide. If four or more bunch rot sprays are applied in a season, use a maximum of two sprays containing a Group 9 fungicide. Capsicum, cucumbers, and strawberries: If three or fewer Botrytis fungicide sprays are applied per crop, use only one spray containing a Group 9 fungicide. If four to six sprays are applied per crop use a maximum of two sprays containing a Group 9 fungicide. If seven or more sprays are applied per crop use a maximum of three sprays containing a Group 9 fungicide. Note: In the absence of an established resistance management strategy for a particular crop/disease situation, it is recommended that: • The use of fungicides from any given activity group (excluding Group M) be limited to a maximum of 1/3 of the total number of fungicide applications per crop. • A maximum of two consecutive applications of SWITCH are to be applied, including from one season/crop to the next.

PRECAUTION Re-entry Period: After application, DO NOT enter treated areas until the spray has dried unless wearing cotton overalls buttoned to the neck and wrist (or equivalent clothing) and chemical resistant gloves. Clothing must be laundered after each day’s use.

INTEGRATED PEST MANAGEMENT Based on the available information it cannot be ruled out that SWITCH may have an adverse effect on beneficial invertebrates where integrated pest management is practiced.


PROTECTION OF HONEY BEES AND OTHER INSECT POLLINATORS DO NOT spray apple trees while bees are actively foraging. DO NOT allow spray to drift from apple trees onto flowering weeds or flowering crops in the vicinity of the apple orchard.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT Very toxic to aquatic life. DO NOT contaminate wetlands or watercourses with this product or used containers.
