GROUP J HERBICIDE

For the control of barnyard grass and certain annual sedges including dirty Dora in rice as per the DIRECTIONS FOR USE table

Resistant Weeds Warning
Saturn EC Rice Herbicide is a member of the thiocarbamate group of herbicides. Saturn has the inhibition of fat synthesis (Not ACCase inhibitors) mode of action. For weed resistance management, Saturn is a Group J herbicide. Some naturally occurring weed biotypes resistant to Saturn, and other Group J herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Saturn or other Group J herbicides.
Since occurrence of resistant weeds is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of Saturn to control resistant weeds.

AERIAL SOWN RICE - DRY SOIL APPLICATION

DIRECTIONS FOR USE (For use in NSW and Vic only)
Restraints
DO NOT use on bays that have not been rolled to break down soil clods prior to application.
DO NOT use on rice varieties other than Amaroo.
DO NOT use where muddy water can be expected.

RICE
(aerial sown into flooded bay - Amaroo variety only)
Weeds controlled: Barnyard grass (Echinochloa spp.), dirty Dora (Cyperus difformis)
Rate / ha: 3.75 to 5.0 L
Critical comments: Apply to weed and clod-free dry soil following rolling. Use the higher rates in areas of anticipated higher weed infestation.
Flood bays as soon as possible after application and no later than 5 days after application or efficacy will be reduced.

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIOD NOT REQUIRED WHEN USED AS DIRECTED.

GENERAL INSTRUCTIONS
Saturn should only be used pre-flooding where bays have been adequately prepared and rolled to break down soil clods. Sow pre-germinated rice seed (not dry rice seed) into flooded bays, maintaining water coverage on high sides of bays.

Mixing
Thoroughly mix the required amount of Saturn with a similar quantity of water before adding the remainder of water to the spray tank while agitating. Re-agitate if the mixture is allowed to stand before use.

Application
Apply via tapered flat fan nozzles in a minimum 50 L/ha. Overlapping may result in crop injury and should be avoided.

Water Management
For best results, supply water separately to each bay from the supply channel or align irrigation stops on one side of paddock and ensure toe furrows are clear.
After completion of initial flooding following application, complete water coverage of bays must be maintained to ensure satisfactory weed control throughout the season. If water levels drop and expose the soil surface, reduced weed control may occur.
DO NOT drain rice water into regional drains within the withholding period after Saturn application as defined by the NSW Environment Protection Authority (EPA) or the local irrigation authority.

AERIAL SOWN RICE - FLOODED BAY - SINGLE APPLICATION

DIRECTIONS FOR USE (For use in NSW and Vic only)
Restraint
DO NOT use Saturn where muddy water can be expected.

RICE
(aerial sown into flooded bay)
Weeds controlled: Barnyard grass (Echinochloa spp.), dirty Dora (Cyperus difformis)
Rate / ha: 3.75 L
Critical comments: Apply Saturn when barnyard grass is at the 0 to 3 leaf stage and dirty Dora is at the 0 to 2 leaf stage.
Apply by air or SCWIIRT to flooded bays only, once the rice has developed to the secondary (fibrous) root stage. Do NOT apply to floating rice or rice that has not developed to the fibrous root (secondary root) stage.
(See comments also under Application and Water Management).

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIOD NOT REQUIRED WHEN USED AS DIRECTED.

GENERAL INSTRUCTIONS
Flood area to be sown quickly and sow within 7 days of commencement of filling of flat bays. Sow pre-germinated rice seed (not dry rice seed) in the normal way maintaining full water coverage on high sides of bay. Apply Saturn only when the fibrous (secondary) roots of the rice seedling are developing and are attached to the soil surface. At this stage the rice seedling is normally in the 1 to 2 leaf stage. This stage normally occurs 7 to 20 days after sowing depending upon temperature conditions (See diagram below). Do NOT apply to rice prior to the development of fibrous roots or to floating rice as crop damage may occur.
Water movement should cease 6 to 12 hours before application and water should be held for a minimum of 3 days. Refer to Water Management below.

Application
Aerial Application
Apply Saturn to flooded bays.
Use flat fan nozzles or AU 5000 rotary atomisers delivering a minimum of 20 to 40 L spray volume/ha with a droplet size of 200 to 350 μm to ensure thorough, even distribution of Saturn.
Alternatively, apply through solid stream nozzles i.e. a Bickley boom with the following setup;
- Two nozzles mounted on droppers, one either side with droppers positioned just outside the first boom hanger (28 – 35% of wingspan).
- Dropper length approximately 40-60 cm or lower below the trailing edge of the wing.
- Solid stream nozzles with bore sufficient to apply desired volume at a pressure of 240 to 310 kPa (35 to 45 psi).
- Nozzles orientated rearwards and parallel to the airstream.
- Check valves (Spraying Systems diaphragm type 12328, ¾ inch) located behind nozzle to eliminate “trailing” after shut off.
For Bickley boom application spray at a maximum wheel height of 2 m above the water surface and at a maximum swath width of 25 m. Ensure a minimum water depth of 10 cm on the high side of bays prior to treatment. A minimum application volume of 20 L/ha is recommended.
Before applying Saturn to contoured bays evaluate the layout of the bays to be treated and select the optimum flight pattern to ensure all bays receive the recommended rate of Saturn.
Thoroughly mix the required amount of Saturn with a similar quantity of water before adding the remainder of water to the spray tank while agitating. Re-agitate if the mixture is allowed to stand before use.
Do NOT over spray headlands.

SCWIIRT Application
Soluble Chemical Water Injection In Rice Technique (SCWIIRT) involves metering herbicide concentrates directly into flooded fields and relying on aqueous dispersion of the chemical across the field. Four-wheel drive vehicles or helicopters are adapted to meter chemical diluted in a small quantity of water directly into flooded bays. In this use situation Saturn is best applied in a SCWIIRT system with a total application volume of 6.5 L/ha. Thoroughly mix the required amount of Saturn with the majority of water before adding the remainder of water to the spray tank while agitating. Re-agitate if the mixture is allowed to stand before use.

Water Management
After a minimum of 3 days following application, bays may be topped up as necessary for normal water management. Ensure full coverage of soil with enough water depth to enable distribution of product throughout the bay. Occasionally crop effects may be observed after the 3 day lock up period. Reducing the water level will assist crop recovery. Contact Bayer CropScience for further advice.
DO NOT drain rice water into regional drains within the withholding period after Saturn application as defined by the NSW Environment Protection Authority (EPA) or the local irrigation authority.

Compatibility
Saturn is compatible for use with Londax® in a resistance management strategy. Consult the Department of Agriculture Information Bulletin for further information on this strategy.

AERIAL SOWN RICE - FLOODED BAY - SPLIT APPLICATION

DIRECTIONS FOR USE (For use in NSW and Vic only)
Restraints
DO NOT use Saturn where muddy water can be expected.
DO NOT use Saturn if contours of bays exceed 10 cm (4 inches).

RICE
(aerial sown into flooded bay) - excluding long grain varieties and Paragon variety
Weeds controlled: Barnyard grass (Echinochloa spp.), dirty Dora (Cyperus difformis)
Rate / ha: 1.0 to 1.5 L
Critical comments: 1st Application - Pre-sowing
Apply by air or SCWIIRT to newly flooded bays prior to weed germination.
Use the low rate only under situations of low anticipated weed pressure.
The higher rate will provide more reliable control where some weeds may have commenced germination or where weed levels are expected to be high.
(Note: Application to bays in which weed germination has occurred may result in unsatisfactory weed control.)
Rate / ha: 2.75 L
Critical comments: 2nd Application - Post-sowing
Apply as soon as possible after secondary (fibrous) root attachment, by air or SCWIIRT to flooded bays.
Apply Saturn when barnyard grass is at the 0 to 3 leaf stage and dirty Dora is at the 0 to 2 leaf stage.
Do NOT apply to floating rice or rice that has not developed to the fibrous root (secondary root) stage.
(See comments also under Application and Water Management)

(aerial sown into flooded bay) - Langi variety and Paragon variety only
Weeds controlled: Barnyard grass (Echinochloa spp.), dirty Dora (Cyperus difformis)
Rate / ha: 1.0 L
Critical comments: The Split Application technique should be used in Langi and Paragon variety rice, only in situations of low anticipated weed pressure.
1st Application - Pre-sowing
Apply by air or SCWIIRT to newly flooded bays prior to weed germination.
(Note: Application to bays in which weed germination has occurred may result in unsatisfactory weed control.)
Rate / ha: 2.75 L
Critical comments: 2nd Application - Post-sowing
Refer to Critical Comments above, for “Rice - excluding long grain varieties and Paragon variety”.

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIOD NOT REQUIRED WHEN USED AS DIRECTED.

GENERAL INSTRUCTIONS
In using the Split Application technique it is essential that both the 1st and 2nd applications are applied. The 1st (pre-sowing) application suppresses weed germinations allowing the rice to develop to the secondary root stage at which time the 2nd (post-sowing) application is required for the control of emerging weeds, completing the herbicide program. If one application is applied without the other the technique will result in unsatisfactory weed control. If certain conditions prevent the second application of Saturn from being applied at the correct stage, alternative products (eg. molinate or Londax) should be used for post-emergence weed control.

1ST APPLICATION - Pre-Sowing
Flood area to be sown over a period not longer than 7 days.
Apply Saturn to bays within 7 days of commencement of filling and 6 to 12 hours after all water movement has ceased, prior to germination of weeds. Sow pre-germinated rice seed (not dry rice seed) 1 to 3 days after treatment. Refer to Water Management below.

Application
Aerial Application

- Dropper length approximately 40-60 cm or lower below the trailing edge of the wing.
- Solid stream nozzles with bore sufficient to apply desired volume at a pressure of 240 to 310 kPa (35 to 45 psi).
- Nozzles orientated rearwards and parallel to the airstream.
- Check valves (Spraying Systems diaphragm type 12328, ¾ inch) located behind nozzle to eliminate “trailing” after shut off.
For Bickley boom application spray at a maximum wheel height of 2 m above the water surface and at a maximum swath width of 25 m. Ensure a minimum water depth of 10 cm on the high side of bays prior to treatment. A minimum application volume of 20 L/ha is recommended.
Before applying Saturn to contoured bays evaluate the layout of the bays to be treated and select the optimum flight pattern to ensure all bays receive the recommended rate of Saturn.
Thoroughly mix the required amount of Saturn with a similar quantity of water before adding the remainder of water to the spray tank while agitating. Re-agitate if the mixture is allowed to stand before use.
Do NOT over spray headlands.

SCWIIRT Application
Soluble Chemical Water Injection In Rice Technique (SCWIIRT) involves metering herbicide concentrates directly into flooded fields and relying on aqueous dispersion of the chemical across the field. Four-wheel drive vehicles or helicopters are adapted to meter chemical diluted in a small quantity of water directly into flooded bays. In this use situation Saturn is best applied in a SCWIIRT system with a total application volume of 5 L/ha. Thoroughly mix the required amount of Saturn with a similar quantity of water before adding the remainder of water to the spray tank while agitating. Re-agitate if the mixture is allowed to stand before use.

Water Management
DO NOT top up bays within 3 days after application. After a minimum of 3 days following application, top up water levels to ensure the high side of the bay is adequately covered.
DO NOT drain rice water into regional drains within the withholding period after Saturn application as defined by the NSW Environment Protection Authority (EPA) or the local irrigation authority.
After completion of initial flooding, complete water coverage of rice bays must be maintained to ensure satisfactory weed control throughout the season. If water levels drop to expose the soil surface, reduced weed control may occur.

2ND APPLICATION - Post-Sowing
Apply Saturn as soon as possible after the development of fibrous (secondary) roots of the rice seedlings and their attachment to the soil surface. At this stage the rice seedling is normally at the 1 to 2 leaf stage. This stage normally occurs 7 to 20 days after sowing depending upon temperature conditions (see diagram below). Do NOT apply to rice prior to the development of fibrous roots or to floating rice, as crop damage may occur.
Water movement should cease 6 to 12 hours before application and water should be held for a minimum of 3 days. Refer to Water Management below.

Ensure full coverage of soil with enough water depth to enable distribution of product throughout the bay. Occasionally crop effects may be observed after the 3 day lock up period. Reducing the water level will assist crop recovery. Contact Bayer CropScience for further advice.
DO NOT drain rice water into regional drains within the withholding period after Saturn application as defined by the NSW Environment Protection Authority (EPA) or the local irrigation authority.

Compatibility
Saturn is compatible for use with Londax in the 2nd Application of the Split Application, as part of a resistance management strategy. Consult the Department of Agriculture Information Bulletin for further information on this strategy. In Langi rice do not apply Londax in mixture with Saturn at rates greater than 70 g Londax/ha.

COMBINE AND PASTURE SOD SOWN RICE

DIRECTIONS FOR USE
Restraints
DO NOT apply Saturn to germinating or emerging rice (0 to 1.5 leaf stage) if ponding is likely to occur in low areas for more than 3 days.
DO NOT use Saturn where irrigation layouts do not permit complete water coverage of the majority of weed growth.
DO NOT apply Saturn to rice sod sown into burnt stubble.

RICE
(combine and pasture sod sown)

Weeds controlled: Barnyard grass (Echinochloa spp.), dirty Dora (Cyperus difformis)
State: NSW, Vic, WA only
Rate / ha: 3.8 L Saturn + 4.2 L of Ronacil®
Critical comments: Use this tank mix when barnyard grass is at the 0 to 5 leaf stage and dirty Dora is at the 0 to 2 leaf stage. Do NOT use when weeds are beyond the leaf stages stated. Use of this mixture is especially recommended with slow-to-establish short-strawed rice varieties. Apply by aircraft or ground-rig only

NOT TO BE USED FOR ANY PURPOSE, OR IN ANY MANNER, CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIOD NOT REQUIRED WHEN USED AS DIRECTED.

GENERAL INSTRUCTIONS
Where rice is sod sown into pasture, it is advisable to use livestock and/or a knockdown herbicide to control the pasture growth prior to sowing.
Prior to rice emergence, if most of the barnyard grass is in the 5 leaf stage and it is unlikely that permanent water will be applied within 10 to 11 days of treatment, the use of a knockdown herbicide is recommended. Apply Saturn or Saturn plus Ronacil mixture later, to control subsequent germination of weeds. Use of this mixture is especially recommended with slow-to-establish, short-strawed rice varieties.
The rice crop should have been flushed at least once prior to application to ensure sealing of the soil surface. Where rice has established on rainfall moisture alone, sealing may not have occurred. Good drainage after flushing is essential.

Application
Saturn can be applied just before or soon after rice emergence but before permanent water is applied.
Apply at low pressures (to either moist or dry soil surface), using ground sprayers delivering 200 L/ha, or by aircraft using flat fan nozzles or AU 5000 rotary atomisers delivering 20 to 40 L/ha with a droplet size of 200 to 350 μm.

Mixing
Thoroughly mix the required amount of Saturn, or Saturn plus Ronacil, with a similar quantity of water before adding the remainder of water to the spray tank, while agitating. Re-agitate if the mixture is allowed to stand before use.

Water Management
Permanent water may be applied as soon as rice plants are at, or past, the 1.5 leaf stage.
DO NOT drain rice water into regional drains within the withholding period after Saturn application as defined by the NSW Environment Protection Authority (EPA) or the local irrigation authority.
(i) Rice Not Ready for Permanent Water
Flushing irrigations should follow spray application within 5 days in the case of Saturn and after 2 days but not later than 5 days in the case of Saturn plus Ronacil. Flushing water must be held for 2 days at a sufficient depth to completely submerge the majority of weed growth and then be drained from the bays. Repeat flushing as necessary to prevent crusting and drying of soil surface. Apply permanent water not later than 10 to 11 days after spray application.
(ii) Rice Ready for Permanent Water
Permanent water should follow spray application within 5 days in the case of Saturn and after 2 days but not later than 5 days in the case of Saturn plus Ronacil. Permanent water should be maintained at a depth to completely submerge the majority of weed growth.

Salvage Control
Where the rice is ready for permanent water and where the barnyard grass is past the 5 leaf stage and up to the early tillering stage, useful suppression and/or partial control may be achieved by higher rates of the Saturn/Ronacil tank mix, with Saturn up to 5 L/ha plus Ronacil up to 7 L/ha. With this treatment some transient leaf scorch of the rice may occur.
Permanent water must be applied after 2 days, but not later than 5 days after application. Permanent water should be maintained at a depth to completely submerge the weed growth for 3 days after application. After this time normal water coverage should be maintained.
