WARNING
AMISTAR 250 SC is extremely phytotoxic to certain apple varieties.
AVOID SPRAY DRIFT. Extreme care must be used to prevent injury to apple trees.
DO NOT spray AMISTAR 250 SC where spray drift may reach apple trees.
DO NOT spray when conditions favour drift beyond the area intended for application. Conditions that may contribute to drift include thermal inversions, excessive wind speed, certain sprayer nozzle/pressure combinations, small spray droplet size, etc.
DO NOT use spray equipment that has been previously used to apply AMISTAR 250 SC to spray apple trees. Even trace amounts can cause unacceptable phytotoxicty.

GENERAL INSTRUCTIONS
Application
DO NOT use concentration factors exceeding 4X when applying through low volume application equipment, except when applying AMISTAR 250 SC by air. In these cases adequate coverage of all plant surfaces is still required to achieve control of diseases.
Tree Crops and Vines
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 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 spraying can then be calculated in the following way:

Example only
1. Dilute spray volume as determined above: for example 1000 L/ha
2. Your chosen concentrate spray volume: for example 500 L/ha
3. The concentration factor in this example is: 2 x (ie 1000 L  500 L = 2)
4. If the dilute label rate is 80 mL/100 L, then the concentrate rate becomes 2 x 80, that is 160 mL/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.

Mixing
Half fill the spray tank with clean water and start agitation. Shake the closed AMISTAR 250 SC container. Whilst filling the remainder of the spray tank add the required amount of AMISTAR 250 SC, adding any tank mix products last. Maintain agitation until spraying is complete. DO NOT leave the spray mix in the sprayer overnight.

Compatibility/Tank Mixing
AMISTAR 250 SC may be mixed in the spray vat with any one of the following products: Ambush, Bravo, Captan* WG, copper hydroxide, Dominex* 100, Dipel* DF, Fortress* 500, Karate, Larvin* 375, Talstar* 80SC, Thiodan*.
A mixture of AMISTAR 250 SC with more than one of these products or with any other product may be ineffective or may cause serious damage. The use of such a mixture is not recommended and would therefore be entirely at the user’s risk.
If tank mixes are to be used observe all directions, precautions and limitations on all products to be used.
As formulations of other manufacturer’s products are beyond the control of Syngenta and water quality varies with location, all mixtures should be tested prior to mixing commercial quantities.
Note: On some tomato varieties, tank mixtures of AMISTAR 250 SC and Lorsban* 500 EC or Nitofol* or Kelthane* MF or Lebaycid* or Supracide have been found to be phytotoxic. DO NOT tank mix these products with AMISTAR 250 SC.
On some grape varieties, tank mixtures of AMISTAR 250 SC and Lorsban 500 EC have been found to be phytotoxic. DO NOT tank mix AMISTAR 250 SC with Lorsban 500 EC for use in grapes.

Fungicide Resistance Warning
AMISTAR 250 SC Fungicide is a member of the Strobilurin and related products group of fungicides. For fungicide resistance management the product is a Group 11 fungicide.
Some naturally occurring individual fungi resistant to the product and other Group 11 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 11 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 Australia Pty Ltd accepts no liability for any losses that may result from the failure of this product to control resistant fungi.

Resistance Management
Amistar 250 SC should be applied in a protective spray program containing fungicides from different chemical group/s. DO NOT wait until disease levels have built up to make applications as this reduces the effectiveness of control and increases risk of resistance development. Disease control may be reduced if strains of pathogens less sensitive to AMISTAR 250 SC develop.
AMISTAR 250 SC should be applied as specified in the Directions for Use in association with the following CropLife Fungicide Resistance Management Strategies:
- DO NOT apply more than 1/3 of the total fungicide sprays per crop as AMISTAR 250 SC.
- A maximum of 2 consecutive applications of AMISTAR 250 SC are to be applied. They must be followed by at least the same number of applications of fungicide(s) from a different fungicide group(s), before AMISTAR 250 SC is used again in that crop.
- Where crops are grown successively alternation should continue between crops.
