GROUP 3 FUNGICIDE

For the control of various diseases in wheat, barley, oats, triticale, canola and pyrethrum as specified in the DIRECTIONS FOR USE table

GENERAL INSTRUCTIONS
Foliar diseases on cereal crops
Monitor the crop regularly for symptoms of disease. Generally spray at the first sign of disease, although this will depend on factors such as expected weather conditions and the particular crop variety resistance. Refer to Directions for Use for particular disease recommendations. Up to two sprays of Prosaro may be applied per season to the crop. Ensure good coverage of all susceptible plant parts.

Disease control in oats
Caution: Application of tebuconazole (present in Prosaro) to some varieties of oats may result in early senescing and bronzing of leaves.
Varieties most at risk may also exhibit this trait under various stress conditions not related to fungicide sprays.
Mitika variety of oats has been identified as being susceptible to this condition when tebuconazole is applied, although other varieties may also be susceptible.
The potential disease control to be achieved by using Prosaro in Mitika oats should be weighed against the risk of crop damage.

Disease control in canola
Blackleg
Higher blackleg risk can be expected in higher rainfall districts (above 500 mm annual rainfall), where crops are grown within 500 m of a previous year’s stubble and in later sown crops (May to August). Other factors will also increase the risk of blackleg infection, including the intensity of canola cropping in a district, rainfall before sowing and the frequency of growing the same canola cultivar. Consult industry guidelines for more detailed assessment of blackleg risk in specific situations. Up to two sprays of Prosaro may be applied per season to the crop.

Sclerotinia
Prosaro is most effective when application is made prior to conditions conducive to sclerotinia infection.
Infection and disease development are most conducive in warmer winter or spring conditions with extended periods of leaf wetness due to rainfall, dew and high humidity. Sclerotinia is most likely to develop where day temperatures are warmer coinciding with a saturated soil profile and rainfall events. Refer also to industry guidelines for advice on conditions under which sclerotinia are most likely to develop.
Control of sclerotinia stem rot is more effective in crops which have a uniform flowering. Uneven flowering (e.g. caused by staggered germinations) makes optimum spray timing difficult and two sprays may be required in these crops.
Generally a single application of Prosaro at 20 to 30% flowering will control sclerotinia in crops with a short flowering interval. Crops with an extended flowering period may require a second application prior to 50% flowering (full-bloom) to adequately control sclerotinia if conditions late in the season are conducive to development of disease.
Length of protection may be reduced in bulky crops where coverage is difficult and where there is growth dilution of the fungicide. For optimum protection, application should be directed to obtain coverage on petals, leaves and stems.

Disease control in pyrethrum
Apply only as instructed by the pyrethrum adviser.

Fungicide Resistance Warning
Prosaro 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, Bayer CropScience accepts no liability for any losses that result from failure of this product to control resistant fungi.

Export of treated produce
Growers should note that MRLs or import tolerances do not exist in all markets for produce treated with Prosaro. If you are growing produce for export, please check with Bayer CropScience for the latest information on MRLs and import tolerances before using Prosaro.

Mixing
Prior to pouring, shake container vigorously, then add the required quantity of Prosaro 420 SC to water in the spray vat with agitators in motion. Add the required amount of adjuvant if necessary and mix thoroughly.
