FORMULATION & ACTIVE INGREDIENT: SWITCH is a water dispersible granule formulation containing 37.5% w/w cyprodinil and 25% w/w fludioxonil

PROPERTIES OF SWITCH
SWITCH is a fungicide containing cyprodinil and fludioxonil and is best used as a protectant treatment or in the earliest stages of disease development.
SWITCH may be used as part of a programme of sprays. To maintain a high level of protection, and to prevent or limit the development of Botrytis strains less sensitive to the product, applications of SWITCH should not be made consecutively but should be used in alternation with fungicides with different modes of action, with satisfactory efficacy against the pathogen.

OUTDOOR AND PROTECTED STRAWBERRIES
Rate of Use
1 kg product in 2000 litres of water per hectare

Timing
For optimum results apply SWITCH from the commencement of flowering until the end of flowering. Up to a total of 3 applications of SWITCH can be made if disease pressure remains high. Allow a minimum of 7-12 days between applications.

Crop Tolerance
SWITCH has been successfully used at the recommended doses on a range of species and cultivars without crop damage. However because of the large number of species and cultivars of ornamentals, the cultivar susceptibility should always be checked by treating a small number of plants in the first instance.
Multiple applications of SWITCH to Anemone, Begonia, Kalanchoë have shown some phytotoxicity symptoms therefore it is advised to limit the number of applications to two with an extended application interval of 10 days. Use only a single application on Saint Paulia. Application to Exacum affine and Impatiens spp. is advised against.


Mixing and spraying

Make sure the sprayer is set to give an even application at the correct volume. Fill the spray tank with half the required volume of clean water and start agitation. Add the required amount of SWITCH to the spray tank. Agitate the mixture thoroughly before use and continue agitation during spraying. Thoroughly wash all spray equipment with water immediately after use.
Wash out containers thoroughly, preferably using an integrated pressure rinsing device, or manually rinse three times. Add washings to the sprayer at the time of filling. Complete filling to the required volume and continue to agitate throughout the spraying operation.
Do not leave the spray liquid in the sprayer for long periods (such as during meal breaks or overnight).
Volume of water and spraying
Apply SWITCH through conventional crop spraying equipment using a medium quality spray (BCPC) at a pressure of at least 2 bar.
After Spraying
Thoroughly wash out sprayer according to manufacturer’s guidelines and dispose of washings and clean containers according to Code of Practice and local water authority guidelines.
