APPLICATION

Rate of use
Maximum individual dose: 0.6 litre per hectare on all named crops
Sprayers should be THOROUGHLY CLEANED before use and filters and jets checked for damage and blockages. A pressure of 2-3 bar (30-40 psi) is recommended.
Apply as a MEDIUM quality spray (as defined by BCPC). Boom height and water volume should be adjusted to ensure good coverage of the crop, particularly at later growth stages. In dense crops at later growth stages, higher water volumes should be used as recommended.

CROP SPECIFIC INFORMATION
CEREALS
Clayton Ohio may be used on all varieties of winter and spring sown wheat (excluding durum wheat), barley, triticale, rye and oats:
Maximum individual dose: 0.6 litre per hectare.
Maximum 2 applications per crop on winter cereals, where a second application is made this must not be applied earlier than early boot/flag leaf extending stage (BBCH 40). Only 1 application may be applied to spring cereals.
Water Volume Clayton Ohio should be applied in 200-400 l/ha of water, with following recommendations.
Most crops 200 litres/hectare
Dense crops after the first node is detectable 250 litres/hectare
Large crops, varieties highly susceptible to disease 300 litres/hectare
Wheat, triticale, barley, rye and oats: CLAYTON OHIO may be applied at any stage before end of flowering (BBCH 69) or 35 days before harvest.

Diseases Controlled - Application Timing
Glume Blotch (Septoria nodorum) (Wheat) and Septoria Leaf Spot (Septoria tritici) (Wheat, triticale).
To protect the flag leaf and ear from Septoria tritici and Septoria nodorum apply CLAYTON OHIO from beginning of stem elongation (BBCH 30) until beginning of flowering (BBCH 61).
Repeated application (winter cereals only) may be necessary where there is a high risk of Septoria tritici - see “Resistance management”. Clayton Ohio should be applied when the disease is active, but before it is visible on the upper leaves. Applications made once foliar symptoms of S. tritici are already present on the upper leaves will be less effective since these symptoms only develop several weeks after initial crop infection has taken place.
Yellow Rust (Puccinia striiformis) and Brown Rust (Puccinia recondita) (Wheat, triticale, barley and rye)
Apply CLAYTON OHIO at the first signs of disease. Applications made to established infections are likely to be less effective. On winter cereals only a second application may be made 2-3 weeks later, but not before flag leaf extending stage (BBCH 41), if reinfection occurs.

Ear Disease Complex (Wheat)
CLAYTON OHIO applied soon after ear emergence can give a good reduction of Fusarium ear blight and a reduction of sooty moulds (Alternaria and Cladosporium) and can result in cleaner, brighter ears. CLAYTON
OHIO applied between early flowering – end of flowering (BBCH 61-69) gives a good control of Fusarium ear blight. Apply CLAYTON OHIO when conditions for Fusarium infection are favourable.

Fusarium Ear Disease (Triticale)
CLAYTON OHIO applied soon after ear emergence can give a good reduction of Fusarium ear blight. CLAYTON
OHIO applied between early flowering – end of flowering (BBCH 61-69) gives a good control of Fusarium ear blight. Apply CLAYTON OHIO when conditions for Fusarium infection are favourable.

Powdery Mildew (Erysiphe graminis) (Triticale and rye)
CLAYTON OHIO should be applied at first signs of disease. When treating established mildew or particularly disease susceptible varieties, improved control can be achieved by adding a half dose fenpropimorph formulation in tank mixture. See recommendations made under 'Resistance Management' and 'Compatibility'.
On winter cereals only, when disease pressure remains high application may be repeated from flag leaf extending stage (BBCH 41), if necessary - see “Resistance management”.
Leaf blotch (Rhynchosporium secalis) (Barley, rye).
Apply CLAYTON OHIO at the onset of disease. On winter cereals only for a moderate control of moderate to severe infections a second application may be necessary 2-3 weeks later but not before flag leaf extending stage (BBCH 41). On disease susceptible varieties in high risk situations tank mixing CLAYTON OHIO with other products may improve control. See recommendations made under 'Resistance Management'.

Net blotch (Pyrenophora teres) (Barley)
Apply CLAYTON OHIO at the very first signs of disease in spring/early summer. On winter cereals only a second application 2-3 weeks later (but not before flag leaf extending stage (BBCH 41)) will give most effective reduction when conditions remain favourable for disease development. See recommendations made under 'Resistance
Management'. When disease develops after flag leaf emergence a single application of CLAYTON OHIO will generally provide good reduction.

Crown Rust (Puccinia coronata) (Oats)
Apply CLAYTON OHIO on first appearance of crown rust.
