Controls Downy Mildew and certain foliar diseases as specified in the Directions for Use

DIRECTIONS FOR USE
Restraints
DO NOT apply more than four sprays per season (except for tobacco).
DO NOT apply this product as a post-infection curative spray on crops as this will favour the development of resistant disease strains. RIDOMIL GOLD MZ WG should always be used within a regular protectant fungicide program.
DO NOT use RIDOMIL GOLD MZ WG for disease control in greenhouse crops.
The effect of RIDOMIL GOLD MZ WG could be diminished if rain falls within 6 hours of application.

GRAPEVINES
Disease Controlled: Downy Mildew (Plasmopara viticola)
State: Qld, NSW, Vic, Tas, SA, WA only
Rate: 
Dilute spraying: 250 g/100 L water
Concentrate spraying: Refer to the Application section
WHP: 14 days
Critical Comments: Apply by dilute or concentrate spraying equipment. Apply the same 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. Use in a protectant program commencing before disease occurs. Limit the use of Group 4 fungicides to periods when conditions favour disease development.
Commence disease control sprays when the grapevine shoots are approximately 20 cm (200 mm) long and continue spraying at 7 to 21 day intervals, using a protectant or non-phenylamide fungicide (not Group 4). Use the shorter interval under prolonged humid and wet conditions. When conditions favour Downy Mildew development (prolonged humid and wet conditions) apply 2 consecutive sprays of RIDOMIL GOLD MZ WG. Apply before the first sign of oil spots or as soon as possible after the infection period. DO NOT apply more than 2 consecutive sprays of a Group 4 product. Resume the program of protectant sprays. Apply a maximum of 4 RIDOMIL GOLD MZ WG or Ridomil Gold Plus sprays per season. DO NOT apply to grapevines in flower in Queensland.
Minor phytotoxic reactions on some varieties of grapes may occur under certain conditions.
Dilute spraying: Apply to the point of runoff. Use a minimum of 500 L mixture/ha before flowering, increasing volume to a minimum of 1,000 L/ha when vines are in full foliage.
Concentrate spraying: Use a minimum of 125 L mixture/ha before flowering, increasing volume to a minimum of 250 L/ha when vines are in full foliage.

GENERAL INSTRUCTIONS
Mixing
RIDOMIL GOLD MZ WG 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 and while spraying.
Tank Mixing: When mixing RIDOMIL GOLD MZ WG 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
Application in Vine Crops
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 Direction 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:
- 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 250 g/100 L, then the concentrate rate becomes 4 x 250, that is 1 L/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.

Compatibility
RIDOMIL GOLD MZ WG is compatible with Supracide® 400, Lannate*L, Morestan*, Benlate*, Afugan*, Pirimor®, Kocide*, non-ionic surfactants, and some formulations of carbaryl, diazinon, dicofol, endosulfan, sulphur and copper oxychloride.

GROUP 4 M3 FUNGICIDE

Fungicide Resistance Warning
RIDOMIL GOLD MZ WG is a combination of a phenylamide and a dithiocarbamate fungicide. For fungicide resistance management RIDOMIL GOLD MZ WG is both a Group 4 and a Group M3 fungicide. Some naturally occurring individual fungi resistant to RIDOMIL GOLD MZ and other Group 4 and/or Group M3 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 RIDOMIL GOLD MZ WG and other Group 4 and/or Group M3 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 Crop Protection Pty Limited accepts no liability for any losses that may result from the failure of RIDOMIL GOLD MZ WG to control resistant fungi.
