Sportak fungicide prochloraz imidazole

Fungicide Resistance Warning

Sportak is a member of the imidazole group of fungicides. For fungicide resistance management Sportak is a Group 3 fungicide. Some naturally occurring individual fungi resistant to Sportak and other Group 3 fungicides may exist through normal genetic variability in any fungal population. The resistant individuals can eventually dominate the fungi population if these fungicides are used repeatedly. These resistant fungi will not be controlled by Sportak and other Group 3 fungicides, resulting in a reduction in efficacy and possible yield loss. Since the occurrence of resistant fungi is difficult to detect prior to use, FMC Australasia Pty Ltd accepts no liability for any losses that may result from the failure of Sportak to control resistant fungi.

Resistance Management Strategies

Resistant strains of fungi can develop to this and other fungicides, and therefore it is recommended that the following strategies be adopted to reduce the possibility of this occurrence:

Post-harvest Dipping of Fruit

1. Handle fruit carefully to minimise potential infection sites caused by injury.

2. Ensure diseased fruit is promptly removed from the field and packing house and destroyed.

3. Dip fruit with a recommended fungicide promptly after harvest.

4 Don’t store fruit in the packing house - move it through the packing house quickly.

5. Dispose of mouldy fungicide-treated fruit at harvest - do not bring it into the packing house.

6. For the last pre-harvest spray, use a fungicide with a different mode of action to the fungicide planned for use as a post-harvest dip.

7. Resistant strains of fungi can develop within the packing house. Where alternatives are available, rotate to use products with as many different modes of action as possible.

8. Remove mouldy fruit from storage - isolate from other fruit.

9. Do not move fruit between packing houses - especially mouldy fruit.

Export of Treated Produce:

Growers should note that suitable MRLs or import tolerances may not be established in all markets for produce treated with Sportak. If you are growing produce for export, please check with FMC Australasia Pty Ltd for the latest information on MRLs and import tolerances BEFORE using Sportak.

Mixing

Add the required amount of Sportak to the water in the dip or spray tank/reservoir and stir thoroughly to ensure complete mixing. Prepare and use spray and dip solutions only in well-ventilated areas.

Application

Post-harvest:

Dip pineapples as directed. For tropical fruits, Sportak should be used in non-recirculating spray systems only. Produce should be treated as soon as possible after harvest. Good coverage is essential. Fruit should be treated at shed temperature. Spraying equipment should be adjusted to ensure exposure of fruit for the periods recommended in the CRITICAL COMMENTS. Do NOT use this product as a foliar spray on fruit trees, as it may cause burning of foliage.
