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

CROP SPECIFIC INFORMATION
Best results will be achieved from applications of SWITCH made in the earliest stage of disease development or as a protective treatment following a disease risk assessment  or the use of appropriate support  systems.
Fresh beans (Dwarf French, green, runner, broad beans) and Dried beans (Dwarf french, navy [phaseolus], kidney, haricot, dried broad beans
Rate Of Use
1 kg product per  hectare
Timing
SWITCH should be applied at the first signs of disease infection, from early flowering onwards.
A second application may be required if disease pressure remains high. Allow a minimum of 10 days between applications for all   crops.
 
Beans For Processing
Where a crop of beans is destined for processing, consult your processor before treating with SWITCH.
Vining peas, edible podded peas and dried peas (combining peas including   marrowfat
Rate Of Use
1 kg product per  hectare
Timing
SWITCH should be applied at the first sign of disease infection, from early flowering onwards.
A second application may be required if disease pressure remains high. Allow a minimum of 10 days between applications for all   crops.
Crop Safety
SWITCH shows good crop safety on vining peas. Before applying ensure the crop is free from any stress caused by environment or agronomic effects. Check wax level if necessary using the Crystal Violet test
 
Peas For Processing
Where a crop of peas is destined for processing, consult your processor before treating with SWITCH.
 
Carrots
Rate Of Use
0.8 kg product per  hectare
Timing
For optimum results apply SWITCH at the first signs of disease, from 4th true leaf unfolded onwards (BBCH 14). A further two applications may be required if disease pressure remains high. Allow a minimum of 12 days between  applications.
Carrots For Processing
Where a crop is destined for processing, consult your processor before treating with SWITCH.
 
Celeriac
Rate Of Use
0.8 kg product per  hectare
 
Timing
For optimum results apply SWITCH at the first signs of disease, from 4th true leaf unfolded onwards (BBCH 14). A second application may be required if disease pressure remains high. Allow a minimum of 14 days between applications for   crops.
 
Protected and outdoor strawberries
Rate Of Use
1 kg product per  hectare
Timing
For optimum results apply SWITCH as a protectant spray at the beginning of blossom (white bud). A second application of SWITCH can be made if disease pressure remains high. Application should be made in sequence with other products as part of a   fungicide programme during flowering at a minimum interval of 10   days.
Strawberries For Processing
Where a crop of strawberries is destined for processing, consult your processor before treating with SWITCH.
 
Raspberry and blackberry
Rate Of Use
1 kg product per  hectare
Timing
SWITCH should be applied as a protectant spray from early flower (white  bud).
A further two applications may be required if disease pressure remains high. Allow a minimum of 10 days between applications for all   crops.
Processing
Where a crop of fruit is destined for processing, consult your processor before treating with SWITCH.
 
Outdoor crops of blueberry, bilberry, cranberry, redcurrant, blackcurrant, whitecurrant and gooseberry
Rate Of Use
1 kg product per  hectare
Timing
SWITCH should be applied as a protectant spray from late grape stage of currants and first open flower for gooseberry and other  berries
A further two applications may be required if disease pressure remains high. Allow a minimum of 10 days between the first and second application and 28 days between the second and third  application
Processing
Where a crop of fruit is destined for processing, consult your processor before treating with SWITCH.
 
Apple, crab apple, quince and  pear
Rate Of Use
0.8 kg product per  hectare
Timing
For optimum results apply SWITCH as a protectant spray from the end of flowering.   Two further applications of SWITCH can be made if disease pressure remains high up   to 3 days prior to harvest. Application should be made in sequence with other products as part of a fungicide programme. Allow a minimum of 7 days between   applications.
For best control of Stemphylium in pears three applications should be made shortly after fruit set in late May and early  June.
Specific warning for Bramley apple
Limited trials data show that when SWITCH is used on Bramley apple there is the potential for increased fruit russeting to occur. Growers should be aware of this and consult with the processor / marketing desk if necessary before using the    product.
 
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 adviced to limit the number of applications to   two with an extended application interval of 10   days.
Use only a single application on Saintpaulia.
Application to Exacum affine and Impatiens spp. is advised  against.
 
 
RECOMMENDATIONS
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.
