Controls Black Spot (Apple Scab and Pear Scab) of Apples and Pears, and Blossom Blight and Brown Rot of Apricots, Peaches, Plums and Nectarines

DIRECTIONS FOR USE
Restraints

The effect of CHORUS could be diminished if rain falls within 2 hours of application DO NOT apply by aircraft

APPLES, PEARS
Disease: 
Apple Scab (Venturia inaequalis), Pear Scab (Venturia pirina)
Rate:
Dilute spraying 40 g/100 L
Concentrate spraying Refer to the Application section
Critical Comments: Apply by dilute or concentrate spraying equipment. Apply the same total amount of product to the target crop whether applying this product by dilute or concentrate spraying methods.
Commence spraying at green tip with an approved fungicide, then apply a maximum of 4 applications of CHORUS between spur burst and petal fall at 7 to 10 day intervals.
Add 25 mL/100 L of a 100% non-ionic surfactant. Ensure thorough coverage. Continue the Scab/Black Spot program commencing no later than 7 to 10 days after the last CHORUS application, using approved DMI plus protectant fungicides.
DO NOT apply CHORUS after petal fall. DO NOT use at concentrate rates greater than 160 g/100 L of water.
DO NOT apply more than 4 applications of this product to apples and pears per season.

APRICOTS, PEACHES, PLUMS, NECTARINES
Disease: 
Blossom Blight (Monilinia laxa), Brown Rot (Monilinia fructicola)
Rate: 
Dilute spraying 40 g/100 L
Concentrate spraying Refer to the Application section
Critical Comments: Apply by dilute or concentrate spraying equipment. Apply the same total amount of product to the target crop whether applying this product by dilute or concentrate spraying methods.
This use is subject to an CropLife anti- resistance strategy.
Apply a maximum of 3 applications of CHORUS between early blossom and shuckfall. Ensure thorough coverage. Critical application timings between early blossom and shuckfall are: 10% blossom, 100% blossom and shuck fall. After shuckfall continue with a disease control program using alternative chemistry.
DO NOT apply CHORUS after shuckfall. DO NOT use at concentrate rates greater than 160 g/100 L of water.
DO NOT apply more than 3 applications of this product to apricots, peaches, plums or nectarines per season.

GENERAL INSTRUCTIONS
Mixing
CHORUS 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 the surfactant at the completion of filling of the spray tank. Continue agitation while spraying.
Tank Mixing: When mixing CHORUS 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.

Application
Ground Application only
Apply by high volume (dilute) sprayer or by concentrate sprayer.
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 above) 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
- Dilute spray volume as determined above: for example 2,000 L/ha
- Your chosen concentrate spray volume: for example 500 L/ha
- The concentration factor in this example is: 4 x (ie 2,000 L / 500 L = 4)
- If the dilute label rate is 40 g/100 L, then the concentrate rate becomes 4 x 40, that is 160 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. DO NOT use a concentrate rate higher than that specified in the Critical Comments.
For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

Compatibility
CHORUS can be mixed with Anvil, Bogard, Delfin, Gusathion, Insegar, Lorsban, Nustar, Parathion, Pirimor, Supracide, Systhane and Topas.

Fungicide Resistance Warning
CHORUS is a member of the anilinopyrimidine group of fungicides. For fungicide resistance management CHORUS is a Group 9 fungicide. Some naturally occurring individual fungi resistant to CHORUS and other Group 9 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. The resistant fungi will not be controlled by CHORUS and other Group 9fungicides, 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 Crop Protection Pty Limited accepts no liability for any losses that may result from the failure of CHORUS to control resistant fungi.
