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 Mantaray 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 Mantaray) 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 Mantaray in Mitika oats should be weighed against the risk of crop damage. For further information on oat tolerance contact Conquest Crop Protection.

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 Mantaray may be applied per season to the crop. Sclerotinia: Mantaray 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 Mantaray 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.

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

Application: Ground: Wheat, barley, oats and triticale: Apply product using a spray volume of 70 – 100 L/ha and a MEDIUM droplet size category. Canola: Apply product using a spray volume of 60 – 100 L/ha and a MEDIUM droplet size category. Pyrethrum: Apply product using a spray volume of 250 L/ha or above and a MEDIUM droplet size category. Aerial (not pyrethrum): Apply product using a minimum spray volume of 20 L/ha and a MEDIUM droplet size category.
