A fungicide for the control of stem-base, foliar and ear diseases in winter and spring wheat (also reduction of the mycotoxin deoxynivalenol), winter rye, triticale, winter and spring barley and oats.
An emulsifiable concentrate formulation containing 100 g/L (10.3% w/w) prothioconazole, 100 g/L (10.5% w/w) tebuconazole and 250 g/L (26.3%w/w) spiroxamine.

Cello is a mixture of triazolinthione, triazole and spiroketoalamine fungicides recommended for control of a wide range of diseases on winter and spring barley, winter and spring wheat, triticale and winter rye.

Method of application: Tractor mounted sprayer
A spray pressure of 2-3 bar is recommended. Apply Cello in 200-300 litres per hectare water.
Apply as a medium spray quality.

DISEASES CONTROLLED
Wheat and Triticale
Eyespot (reduction of the incidence and severity), Septoria (tritici, glume blotch), powdery mildew, yellow rust, brown rust, tan spot, ear disease complex (Fusarium ear blight (reduction of deoxynivalenol) and reduction of sooty moulds).

Barley
Eyespot (reduction of the incidence and severity), powdery mildew, yellow rust, brown rust, ear disease complex complex (Fusarium ear blight and reduction of sooty moulds), Rhynchosporium, net blotch.

Rye
Eyespot (reduction of the incidence and severity), powdery mildew, brown rust, Rhynchosporium.

Oats
Eyespot, crown rust and mildew.
Eyespot (Oculimacula spp.)
Spray in the spring at the first sign of disease, from when the leaf sheaths begin to become erect until the 2nd node is detectable (GS 30-32).

Septoria Leaf Spot and Glume Blotch (Septoria tritici and Stagonospora nodorum)
Apply before disease is established in the crop. To protect the upper leaves and ear apply Cello at full flag leaf emergence (GS 37) up to mid-flowering (GS 65). Where disease pressure remains high application may be repeated.
Applications to upper leaves where S. tritici symptoms are present are likely to be less effective.

Powdery Mildew (Blumeria graminis)
Apply Cello at the first signs of disease. Where disease pressure remains high application may be repeated.

Yellow Rust (Puccinia striiformis)
Apply Cello at the first signs of disease. A second application may be made 2-3 weeks later if re-infection occurs.
Applications made to established infections are likely to be less effective.

Brown Rust (Puccinia recondita and P. hordei)
Apply Cello at the first signs of disease. A second application may be made 2-3 weeks later if re-infection occurs.
Applications made to established infections are likely to be less effective.

Crown Rust (Puccinia coronata)
Apply Cello at the first signs of disease. Cello controls crown rust in winter and spring oats. A second application may be made 2-3 weeks later if re-infection occurs. Applications made to established infections are likely to be less effective.

Tan Spot (Pyrenophora tritici-repentis)
Apply Cello at the first signs of disease in spring or early summer. Where disease pressure remains high application may be repeated.

Ear Disease Complex
Apply Cello soon after ear emergence until the end of flowering (GS59-69) for control of Fusarium ear blight and reduction of sooty moulds. Control of ear diseases can result in cleaner, brighter ears.
Through the reduction of ear blight, Cello effectively reduces the level of the Fusarium mycotoxin deoxynivalenol (DON) in wheat grain. However, where Fusarium levels are
high, the reduction achieved may not always be sufficient to ensure that DON levels fall below the statutory limit.

Leaf Blotch (Rhynchosporium secalis)
Apply Cello in spring at the first signs of disease. For severe infections a second application may be necessary 2-3 weeks later.

Net Blotch (Pyrenophora teres)
Apply Cello at the first signs of disease in spring/early summer. For severe infections, a second application 2-3 weeks later will give most effective control when conditions remain favourable for disease development.

CAUTION:
The possible development of disease strains resistant to Cello cannot be excluded or predicted. Where such resistant strains occur, Cello is unlikely to give satisfactory control.

CROP SPECIFIC INFORMATION
Cello may be used on all commercial varieties of winter and spring barley, winter and spring oats, winter and spring wheat, winter rye and triticale.

Mixing
Thoroughly shake the pack before use.
Add the required quantity of Cello to the half-filled spray tank with the agitation system in operation and then fill to the required level. Continue agitation at all times during spraying and stoppages until the tank is completely empty. Spray immediately after mixing.

General
Sprayers should be thoroughly cleaned with water and detergent after use, and filters and jets checked for damage and blockages.
Boom height should be adjusted to ensure even coverage of the crop, particularly at later growth stages. The correct height is one at which the spray from alternate nozzles meets just above the crop, in dense crops, at later growth stages, higher water volumes should be used.
