Barley Disease: Didymella leaf scorch, Leaf rust, Net blotch (spot and net form), Ovularia leaf spot, Scald, Spot blotchRate: 750ml/haApply as a preventative spray. If disease is present, or conditions prior to application have been favourable for disease infection the addition of an approved triazole fungicide is recommended. Re-infection may require further treatment 4 to 6 weeks later. Where scald infection pressure is high, it is recommended to apply Tazer in a tank mix with a fungicide from a different chemical group that is approved for use on this disease.Disease: Late season head disease complex (Alternaria, Cladosporium, Microdochium nivale, Stemphylium)Apply as a preventive spray after ear emergence; GS 57-69

Wheat Disease: Leaf rust, Powdery mildew, Speckled leaf blotch, Stripe rustRate: 750ml/haApply as a preventive spray. If disease is present or conditions prior to application have been favourable for disease infection the addition of an approved triazole fungicide is recommended. Re-infection may require further treatment 4 to 6 weeks later. Where powdery mildew infection pressure is high, it is recommended to apply Tazer in a tank mix with a fungicide from a different chemical group that is approved for use on this disease.Disease: Didymella leaf scorchRate: 750ml/haApply as a preventive spray from flag leaf emergence; GS 39 Disease: Glume blotchRate: 750ml/haFor protection of the flag leaf apply as a preventive spray from flag leaf emergence; GS 39-55.

Ryegrass seed crops Disease: Crown rust (leaf rust), Stem rustRate: 750ml/haApply as a preventive spray. If disease is present or conditions prior to application have been favourable for disease infection the addition of an approved triazole fungicide is recommended. Re-infection may require further treatment. The treatment of ryegrass seed cultivars has not shown to have any adverse effects on the endophyte levels in the harvested seed.

Potatoes Disease: Early blight, late blight*Rate: 500ml/haApply in a minimum of 500L water/ha for a crop in full canopy to ensure uniform coverage. Apply as a protective spray at 7 to 10 day intervals during periods of active growth. Intervals can be increased to 10 to 14 days later in the season as haulm growth ceases. Always use the closer intervals during periods of severe disease pressure. Use higher spraying pressure or air assisted equipment to enhance penetration in densely foliated crops.*Under climatic conditions which create severe late blight disease pressure, either tank mix Tazer with 1kg/ha mancozeb (80%) or alternately apply 1 or 2 sprays of a systemic / protectant fungicide, then revert to the use of Tazer.

DO NOT use Tazer or related strobilurin products for more than one third of the total seasonal sprays.

Potatoes “in-furrow” planting application Disease: Black scurf, Silver scurf*Rate: 10ml/100m of rowApply at planting as an “in-furrow” spray in 50 to 150L water/ha. Direct the spray into the furrow just before the tuber is covered with soil as a 15 to 30cm band ensuring the tuber and immediate surrounding soil is sprayed.Do not apply Tazer if conditions or seed quality favour bacterial rots as these diseases may be aggravated if seed comes into contact with additional moisture.Do not apply Tazer if planting in hot, sandy soils as bacterial rots may be aggravated.*suppression only

Sweetcorn, Maize Disease: Rust (Puccinia sorghi), Northern leaf blight (Setosphaeria turcica)Rate: 1L/haApply as a preventative spray especially before but no later than tasselling when disease infection is most likely to occur. A second application may be required 14 days later if disease pressure continues. Do not apply more than 2 applications per season.

Peas (NOT for use on peas to be harvested in pods and consumed whole, eg snow peas and snap peas)Disease: Ascochyta, downy mildew, powdery mildewRate: 500ml/haApply in a minimum of 200L water/ha for a crop in full canopy to ensure uniform coverage. The first application should be made as a protective spray at 5th node to 1st pod formation. A second application 14-21 days later is required if disease pressure remains high. The addition of Contact™ Xcel at recommended label rates will assist crop coverage and spray distribution. Use higher spraying pressure or air assisted equipment to enhance penetration in densely foliated crops. Before applying Tazer ensure the crop is free from any stress caused by environmental or agronomic factors. Application to established downy mildew, ascochyta or powdery mildew will not give reliable control. Note: See Withholding Period section for information on the appropriate withholding period

Onions Disease: Downy mildew, pink rotRate: 500ml/haApply in a minimum of 400L water/ha for a crop in full canopy to ensure uniform coverage. Apply as a protective spray at 7 day intervals from the 2 leaf growth stage or when conditions favour disease infection but prior to disease development. Add Contact Xcel at recommended label rates. Use higher spraying pressure or air assisted equipment to enhance penetration in densely foliated crops. Application to established downy mildew may not give reliable control. Tazer will contribute to the control of pink rot (Phoma terrestris). DO NOT apply more than 4 applications of Tazer per season.Disease: Neck rot (Botrytis allii)Rate: 500ml/haTazer can be applied at key timings for neck rot control i.e. flag leaf and pre harvest. Apply in sufficient water to ensure thorough and uniform coverage. Applications MUST be made with the addition of a non-ionic wetting agent such as Contact Xcel at label rates. Use higher spraying pressure or air assisted equipment to enhance penetration in densely foliated crops. DO NOT apply more than 4 applications of Tazer per season.

Field tomatoes Disease: Early blight, late blight, black mouldRate: 500ml/haApply in a minimum of 500L water/ha for a crop in full canopy to ensure uniform coverage. Apply as a protective spray at 10 to 14 day intervals. Use higher spraying pressure or air assisted equipment to enhance penetration in densely foliated crops. DO NOT apply to field tomatoes with a surfactant or crop oil concentrate.

Grapes Disease: Powdery mildew, downy mildew, botrytis* Rate: 80ml/100 litres of water and apply not less than 800ml Tazer/haApply at 10-14 day intervals from early flowering to pre-harvest. Use the shorter spray intervals during periods of severe disease pressure. *When Tazer is used in a seasonal spray program it will provide control of botrytis additional to that of specific botryticides.

Tazer MUST NOT be used instead of specific botryticides at strategic timings.

Turf Disease: Fairy ring fungiRate: 1.2-2.4L/haApply in 800 – 1600 litres of water/ha

A weapon for fighting

disease and building

yield.

Tazer is the first choice fungicide for use at the T2 (flag leaf – GS 39) and T3 (50% ear emergence to mid flowering – GS 59-65) application timings in cereals. It is highly effective on all the key yield destroying diseases in the target crop.

When applied during stem elongation Tazer will generally provide 4-6 weeks protection from disease. Length of protection from flag or ear emergence applications may extend out for longer depending on the variety, season and crop situation.

It is good agronomic practice to tank mix Tazer with a suitable fungicide partner with a different mode of action which provides curative activity. This will boost the activity if disease is present at application and will also reduce the risk of resistance developing.

Tazer’s unique chemistry also slows leaf senescence and increases the retention of green leaf area in cereal crops. The longer that crop foliage is able to photosynthesize and contribute nutrients to the developing grain, the greater the yield.

In ryegrass seed crops Tazer will provide very effective control of leaf and stem rust without damaging the novel endophytes.

Tazer applied in-furrow at planting will provide superior protection against seed and soil borne rhizoctonia infection and will also suppress silver scurf. Crop yield and tuber quality is improved as a result of reducing rhizoctonia challenge early in the life of the crop. The innovative in-furrow application technique removes the need to double handle seed tubers prior to planting.

Tazer contains 250g/L azoxystrobin, a broad spectrum, protectant fungicide for the control of a wide range of fungal diseases in wheat, barley, potato, sweetcorn, maize, peas, field tomatoes, onions, grapes, turf and ryegrass seed crops.

Mode of Action The mode of action of Tazer provides effective protectant activity. Tazer is systemic and will move from one leaf surface to the other to control germinating fungal spores. Tazer has little curative activity and is best used as a protectant application prior to infection. Crops that are already showing disease symptoms should not be treated with Tazer.

The active ingredient in Tazer inhibits the respiration process in fungal cells and leads to their death, effectively preventing spore germination and the early stages of infection.

Water Rates Ground application: no less than 200L water/ha – increase water rates in dense or advanced crops. Aerial application: no less than 50L water/ha. Consult with your Nufarm Territory Manager for advice on achieving optimum disease control.

Good coverage of foliage is essential for effective control. Tazer is transported in the plants xylem system. The xylem transports the fungicide up towards the leaf tip. It will not move downwards through the plant to compensate for inadequate coverage on lower leaves or stems.

Rainfastness Tazer is rainfast once dried on the plant.

Additional Adjuvants There is not usually any requirement for adding extra wetting agents or surfactants when applying Tazer.

Compatibility Tazer is compatible with most common insecticides and fungicides and plant growth regulator tank mixes.

Application Information

Cereals: Effective disease control and yield increases

Tazer is a member of the strobilurin group of fungicides (Group 11). Many diseases have strains with known resistance to strobilurin fungicides.

Resistance Management Strategies have been developed for strobilurins and these should be adhered to thus ensuring that farmers can continue to take advantage of the benefits of this highly successful group of fungicides.

•Donotrelyonlyonthecurativepotentialofstrobilurinfungicides.

Resistance Management Strategy for Strobilurin Fungicides

Cereals Powdery mildew, speckled leaf blotch, glume blotch, rusts

Apply a maximum of two strobilurin fungicide-containing sprays per cereal crop. Limiting the number of sprays is an important factor in delaying the build-up of resistant pathogen populations. Apply strobilurin fungicides in mixtures to control cereal pathogens. At the rate chosen each mixing partner on its own has to provide effective disease control. Refer to manufacturers’ recommendations for rates. Repeated applications using "split" or reduced application rates must not be used, as they provide continuous selection for resistance.

Grapes Powdery mildew, downy mildew

A maximum of three strobilurin-containing applications per vine crop, in single or block application in alternation with fungicides from a different group. Use early in the season before powdery mildew is well established.

Other fruit and vegetable crops

Apply a maximum of three strobilurin fungicide-containing sprays per crop. A maximum of four strobilurin fungicide applications may be used where 12 or more applications are made per crop. Apply in mixture with an effective dose of a fungicide from a different group. A maximum of two consecutive strobilurin fungicide sprays is preferred.

A fungicide for the control of a wide range of diseases in wheat, barley, potato, sweetcorn, maize and ryegrass seed crops.
