GENERAL INSTRUCTIONS
Fungicide Resistance Warning
CHIEF® 250 Liquid Fungicide is a member of the dicarboximide group of fungicides. For fungicide resistance management CHIEF 250 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 CHIEF 250 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, Adama Australia Pty. Ltd. accepts no liability for any losses that may result from the failure of CHIEF 250 to control resistant fungi.

Export of treated produce
Growers should note that MRLs or import tolerances may not exist in all markets for produce treated with CHIEF 250. If you are growing produce for export, please check with Adama Australia Pty. Ltd. for the latest information on MRLs and import tolerances BEFORE using CHIEF 250.

Mixing
Note: CHIEF 250 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 CHIEF 250. 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.

Application
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 CHIEF 250 in the spray tank may reduce the suspension properties of CHIEF 250, 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 CHIEF® 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 equired to reach the point of run-off) and matched to the crop being sprayed. Set up and operate the sprayer to achieve even overage 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:
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: 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.

Compatibility
CHIEF 250 is compatible with the following products:
#Aliette* WG (see NOTE below), azinphos-methyl, benomyl, Bugmaster* Flowable, chlorfenvinphos, Chlorfos*, demeton-S-methyl, Dithane M45*, fenarimol, Kelthane*, Kocide* (Warning: Do not mix CHIEF 250 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. CHIEF 250)
5. Soluble powders
6. Solutions
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 CHIEF 250 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 CHIEF 250 with Aliette WG may result in some settling out.
As formulations of other manufacturers’ products are beyond the control of Adama Australia Pty. Ltd. all mixtures should be tested prior to mixing commercial quantities.
