Add a non-ionic wetting agent at 10 mL/100 L regardless of whether applying by dilute or concentrate spraying.

PEANUTS
State: South Qld, NSW only
Disease: Early Leaf Spot, Late Leaf Spot, Rust, Net Blotch
Application:
Ground application: Apply in at least 100 L of water/ha
Aerial application: Apply at least 30 L of spray mixture per hectare
Rate: -
WHP: H 3 weeks; G 3 weeks

WHP: H 5 weeks; G 14 days

Critical comments: Use higher rate when longer disease control is required.
Stripe Rust: See spray timings under General Instructions.
Other diseases: Apply from full flag leaf emergence to early head emergence.
The addition of mineral crop oil (eg. D-C-Trate or equivalent) at 1%, may improve performance of ORIUS 430 SC on wheat, oats and barley.

BARLEY
Disease: Scald
Application:
Ground Application: Apply in at least 50 L of water/ha
Aerial Application: Apply in at least 10 L of water/ha
Rate: 145 mL/ha
WHP: H 5 weeks; G 14 days
Critical comments: Apply at late tillering to early jointing.

Disease: Powdery Mildew
Application:
Ground Application: Apply in at least 50 L of water/ha
Aerial Application: Apply in at least 10 L of water/ha
Rate: 145 or 290 mL/ha
WHP: H 5 weeks; G 14 days
Critical comments: Apply when 5% of the leaf area is infected. Use higher rate when longer disease control is required.

WHEAT, OATS
Disease: Stem Rust
Application:
Ground Application: Apply in at least 50 L of water/ha
Aerial Application: Apply in at least 10 L of water/ha
Rate: 145 or 290 mL/ha
WHP: H 5 weeks; G 14 days
Critical comments: Apply if more than 5% of stems become infected between full flag leaf emergence to late flowering. Where Stem Rust is the major disease, yield responses are usually optimised by delaying application until full head emergence, and using the higher rate. In severe cases, if a majority of stems are infected prior to full head emergence, apply at 145 mL/ha as soon as possible and if necessary, repeat after 3 weeks when heads are fully emerged.

ONIONS
State:
Tas only
Disease: White Root Rot
Application: Before sowing, apply ORIUS 430 SC onto lime super. Ensure good coverage of all lime super particles
Rate: 1.45 mL/100 m of row mixed with 145-218 g lime super /100 m of row
WHP:
Critical comments: Apply ORIUS 430 SC treated lime super when sowing onion seed. Seed and lime super can either be mixed in the same box on the drill or placed in different boxes and sown down the same tube. Apply in a band width of 2 cm. Ensure that the correct rate of ORIUS 430 SC is used otherwise some delay in emergence and reduced stands of seedlings may occur.

PAPAW
Disease: Black Spot
Application: Ensure thorough coverage of leaves and fruit
Rate: 290 mL/ha
WHP: 3 days
Critical comments: Ensure infected plant material is regularly removed and destroyed to reduce inoculum levels. Spray equipment must be properly calibrated to apply the correct amount of ORIUS 430 SC. Apply ORIUS 430 SC at 14 day intervals. Alternate ORIUS 430 SC with sprays of a protectant fungicide (eg. Dithane DF). Do not apply more than 6 sprays of ORIUS 430 SC (or any DMI fungicide) on any block in any 12 month period.

RYEGRASS
Disease: Leaf Rust, Stem Rust
Application: Apply in at least 100 L of water/ha
Rate: 290 mL/ha
WHP: -
Critical comments: Monitor crops closely and spray at the first signs of disease. Continuing disease pressure or reinfection may require a further application 3-4 weeks later. Ensure thorough coverage, and use higher water volumes in dense or advanced crops.

SUGARCANE
(variety Q124 only)
Disease: Orange Rust
Application:
Ground Application: Use droppers and directed sprays and sufficient water volume to ensure thorough coverage.
Aerial Application: Apply in a minimum spray volume of 20 L per hectare.
Rate: 290 mL/ha plus Agridex 1 L/ha
WHP: H4 weeks; G4 weeks
Critical comments: Even low levels of Orange Rust suppress yields so it is important to apply ORIUS 430 SC early in the development of the disease epidemic. Begin monitoring disease levels early.
Check crops at least weekly when climatic conditions favour the development of disease. Apply as a foliar spray when disease begins to escalate rapidly. Repeat application after 14 days if conditions remain favourable to Orange Rust spore germination. DO NOT apply more than two ORIUS 430 SC sprays per season. DO NOT apply if heavy rains or storms that are likely to cause
surface run-off are forecast with greater than 50% probability within 24 hours (48 hours if possible) of application.

GENERAL INSTRUCTIONS
Special warning – bananas
There are certain conditions when the surface of recently emerged fruit is particularly prone to marking damage from spray applications. In circumstances where application will be made to very rapidly growing fruit in hot conditions with strong direct light, it is recommended that all emerged bunches be bagged prior to spraying to minimise risk of fruit marking. Never include adjuvants other than water miscible oils with ORIUS 430 SC sprays. The inclusion of wetting agents is known to cause phytotoxicity to young fruit.

Foliar diseases on cereal crops
Do not apply to cereal crops more than once in a season. Treatment will give approximately three weeks disease suppression.
Economic responses may not be gained by spraying crops past flowering stage. The effects of fungicide application will not be clearly seen for 7-10 days after application.
Yield potential: crops with potential yield under 2 t/ha are unlikely to give economic responses to a fungicide spray except under conditions of very severe disease. Economic responses are most likely with crops with potential yield of over 3 t/ha.

Spray timings for stripe rust control
Obtain advisory literature from Department of Agriculture for classification of resistant and susceptible varieties. In South Australia consult Plant Protection Note PPN 21. In other states the following spray program is suggested:
Seedling infections: When approximately 20 out of 100 leaves show first signs of infection during tillering to jointing, apply a spray within one week.
Adult infections - susceptible varieties: When approximately 10 out of 100 leaves show first sign of infection, apply a spray within one week. Do not delay.
Adult infections - moderately susceptible varieties: When approximately 15 to 20 leaves out of 100 leaves show first sign of infection, apply a spray within one week. Do not delay.
Adult infections - moderately resistant and resistant varieties: Monitor carefully. If rust appears and spreads, spray within one week.

Fungicide Resistance Warning
ORIUS® 430 SC Fungicide is a member of the DMI group of fungicides. For fungicide resistance management the product is a Group 3 fungicide. Some naturally occurring individual fungi resistant to the product and other Group 3 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungal population if these fungicides are used repeatedly. These resistant fungi will not be controlled by this product and other Group 3 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, Adama Australia Pty. Ltd. accepts no liability for any losses that result from failure of this product to control resistant fungi.

Resistance management recommendation – peanuts
Apply no more than 3 consecutive sprays of DMI fungicide (eg. ORIUS 430 SC) before switching to a non-DMI fungicide. Apply no more than 5 DMI sprays per season.

Mixing
Prior to pouring, shake container vigorously, then add the required quantity of ORIUS 430 SC to water in the spray vat while stirring or with agitators in motion. Add the required amount of Agridex† (peanuts, beans) or water miscible oil (bananas) and mix thoroughly.

Application
Aircraft should fly as low as possible under the prevailing conditions to minimise drift.
Special Instructions for Grapevines
Dilute Spraying: Use a sprayer designed to apply high volumes of water up to the point of run-off 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 run-off. Avoid excessive run-off. 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 run-off. 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 the concentrate spraying (that is a sprayer which applies water volumes less than those required to reach the point of run-off) 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 can then be calculated in the following way:
EXAMPLE ONLY
1. Dilute spray volume as determined above: For example 1500 L/ha.
2. Your chosen concentrate spray volume: For example 500 L/ha.
3. The concentration factor in this example is: 3x (ie 1500 L ÷ 500 L = 3).
4. If the dilute label rate is 30 mL/100 L, then the concentrate rate becomes 3 x30, that is 90 mL/100 L of concentrate spraying. 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.
