Fungicide Resistance Warning
Rovral Liquid Fungicide is a member of the dicarboximide group of fungicides. For fungicide resistance management the product is a Group 2 fungicide. Some naturally occurring individual fungi resistant to the product and other Group 2 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 or other Group 2 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, FMC Crop Protection Pty Ltd accepts no liability for any losses that may result from the failure of this product to control resistant fungi.

Resistance Management
Resistant strains of fungi can develop to this and other fungicides. To reduce the possibility of this occurrence, and where alternatives are available, rotate to use products with as many different modes of action as possible.
Where specific resistance management strategies are established these are detailed at the CropLife Australia website ( Doc ID=1792) or from your local agronomist.

Export of Treated Produce
Growers should note that MRLs or import tolerances may not exist in all markets for produce treated with Rovral Liquid. If you are growing produce for export, please check with FMC Crop Protection Pty Ltd. for the latest information on MRLs and import tolerances BEFORE using Rovral Liquid.

Note: Rovral Liquid may be unstable in conditions where the pH is 7 or higher. It is therefore essential to check the pH of the spray solution before adding Rovral Liquid. A suitable registered buffering agent may have to be added to bring the pH down below 7.
Shake well before use. Add half the required water volume to the spray tank or vat with the agitation mechanism operating. Add the required volume of this product and then add additional water to the volume required.

Good disease control requires even, thorough coverage of the target area. Application should be made using appropriate spray equipment and sufficient water to provide adequate penetration and coverage. Equipment settings and water volume may need to vary, depending on the growth stage of the crop. High pressure, prolonged and vigorous agitation particularly in conjunction with a high concentration of Rovral Liquid in the spray tank may reduce the suspension properties of Rovral Liquid, resulting in a scum forming on the surface or sediment forming on the filters. If the agitation system cannot be adjusted, or concentration reduced to overcome this problem it is recommended that Rovral Aquaflo be used, where registered.

Special Instructions for Tree Crops/Vines
Dilute Spraying
- Use a sprayer designed to apply high spray volumes, 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 spray solution to cover the crop to the point of run-off. Avoid excessive run-off.
- The required spray volume to achieve point of run-off may be determined by applying different test volumes, using different settings on the sprayer, or from industry guidelines or other 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 to achieve point of run off 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 spray 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 spray 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:
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: 3 X (i.e. 1500 L ÷ 500 L = 3)
4. If the dilute label rate is 10 mL/100 L, then the concentrate rate becomes 3 x 10, that is 30 mL of product per 100 L water for 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.
- For further information on concentrate spraying, users are advised to consult relevant industry guidelines, undertake appropriate competency training and follow industry Best Practices.

Rovral Liquid is compatible with the following products:
Aliette WG (see NOTE below), azinphos-methyl, benomyl, Bugmaster Flowable, chlorfenvinphos, chlorpyrifos (500 g/L EC), demeton-S-methyl, Dithane M45, Thiodan EC (endosulfan), fenarimol, Kelthane, Kocide (Warning: Do not mix Rovral Liquid with Kocide for use on potatoes), Larvin 375, Maldison 500, Marlin, metalaxyl, methamidophos, methyl parathion, pirimicarb, propargite, triadimenol.
When tank mixing products the order of mixing is determined by formulation type.
As a guide the following mixing sequence is recommended:
1.Wettable powders
2.Suspension concentrates
3.Water Dispersible Granules
4.Suspo-emulsions (e.g. Rovral Liquid)
5.Soluble powders
7.Emulsifiable concentrates
8.Soluble concentrates
9.Wetting agents and oils
With any mixture, thoroughly agitate immediately before applying. It is not recommended to mix this product with more than one of the above chemicals in the tank. The use of a surfactant or spray oil is not recommended with Rovral Liquid as it may result in crop damage to sensitive plants. DO NOT mix with fertilisers. Mixtures with some fertilisers, e.g. urea, may cause foliar damage.
NOTE:  Mixing Rovral liquid with Alliette WG may result in some settling out. As formulations of other manufacturers’ products are beyond the control of FMC Crop
Protection Pty Ltd, all mixtures should be tested prior to mixing commercial quantities.

DO NOT apply the product under weather conditions, or from spraying equipment, which could be expected to cause spray drift onto adjacent crops, croplands, pastures, livestock, natural or impounded lakes, dams or other waterways.

Toxic to aquatic organisms. DO NOT contaminate streams, rivers or waterways with the chemical or used containers.
