DIRECTIONS FOR USE

IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Clayton Navaro contains prothioconazole and tebuconazole, both triazole fungicides, recommended for control of a wide range of diseases on certain cereals and winter oilseed rape.

CROPS
Clayton Navaro may be used on all commercial varieties of winter and spring barley, winter and spring wheat, winter rye, winter and spring oats and winter oilseed rape.

RATE OF USE
Apply Clayton Navaro at 1.0 L/ha.

APPLICATION TIMING
A minimum interval of 21 days must be observed between applications in all crops.

CEREALS
Eyespot (Tapesia 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 Blotch and Glume Blotch (Septoria tritici and Stagonospora nodorum)
Apply before disease is established in the crop. To protect the upper leaves and ear apply Clayton
Navaro 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. Clayton Navaro contains two DMI fungicides. Resistance to some DMI fungicides has been identified in Septoria leaf blotch (Mycosphaerella graminicola) which may seriously affect the performance of some products. For further advice on resistance management in DMI’s contact your agronomist or specialist advisor, and visit the FRAG-UK website.
Powdery Mildew (Blumeria graminis)
Apply Clayton Navaro at the first signs of disease. Where disease pressure remains high application may be repeated. Clayton Navaro will only provide moderate control of powdery mildew in wheat

Yellow Rust (Puccinia striiformis)
Apply Clayton Navaro at the first signs of disease. A second application may be made later if reinfection occurs. Applications made to established infections are likely to be less effective.
Brown Rust (Puccinia recondita and P hordei)
Apply Clayton Navaro at the first signs of disease. A second application may be made later if reinfection occurs. Applications made to established infections are likely to be less effective.
Crown Rust (Puccinia coronata)
Apply Clayton Navaro at the first signs of disease. Clayton Navaro controls crown rust in winter and spring oats. A second application may be made later if re-infection occurs. Applications made to established infections are likely to be less effective.
Tan Spot (Pyrenophora tritici-repentis)
Apply Clayton Navaro at the first signs of disease in spring or early summer. Where disease pressure remains high application may be repeated.
Ear Disease Complex
Apply Clayton Navaro soon after ear emergence until the end of flowering (GS 59-69) for control of Fusarium ear blight in wheat (or moderate control in barley) and reduction of sooty moulds. Control of ear diseases can result in cleaner, brighter ears. Through the control of ear blight, Clayton Navaro 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 Clayton Navaro in spring at the first signs of disease. For severe infections a second application may be necessary later.
Net Blotch (Pyrenophora teres)
Apply Clayton Navaro at the first signs of disease in spring/early summer. For severe infections, a second application later will give most effective control when conditions remain favourable for disease development.

Oilseed rape
Light Leaf Spot (moderate control)
Apply Clayton Navaro protectively in autumn/winter (usually late October to early December).
Follow up treatment(s) may be required in early spring from the onset of stem elongation, depending on disease development.
Phoma Leaf spot/Stem Canker
Apply Clayton Navaro in autumn at the first sign of disease. Repeat treatment in late autumn/winter, if disease symptoms reoccur.
Sclerotinia stem rot (Sclerotinia sclerotiorum)
Apply Clayton Navaro at early to full flower.
