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.
Jaunt is a mixture of a triazole and strobilurin fungicides recommended for control of a wide range of diseases on winter and spring wheat, durum wheat, rye, triticale and winter and spring barley.

RESTRICTIONS
PROTECT FROM FROST

DISEASES CONTROLLED
Wheat, durum wheat and triticale
Eyespot (reduction of the incidence and severity), Septoria (leaf and glume blotch), powdery mildew, yellow rust, brown rust, tan spot (in wheat), ear disease complex (Fusarium ear blight*).
Rye
Eyespot, powdery mildew, brown rust and Rhynchosporium
Barley
Eyespot (reduction of the incidence and severity), powdery mildew, brown rust, Rhynchosporium, net blotch.
*Jaunt will provide moderate control of these diseases

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 Leptosphaeria nodorum)
Apply before disease is established in the crop. To protect the upper leaves and ear apply Jaunt 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.
Jaunt contains a DMI fungicide. 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 (Erisiphe graminis)
When used for the control of other diseases, Jaunt will also give control of powdery mildew in wheat, durum wheat, triticale and rye.
Strains of wheat and barley powdery mildew resistant to Qol fungicides are common in the UK. Where specific control of wheat mildew is required, this should be achieved through a programme of measures, including products with recommendations for control of mildew that contain different active substances used in mixture or sequence.
Apply Jaunt at the first signs of disease. Where disease pressure remains high application may be repeated.

Yellow Rust (Puccinia striiformis)
Apply Jaunt 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 hordei and P. recondita)
Apply Jaunt 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.

Ear Disease Complex
Apply Jaunt soon after ear emergence until the end of flowering (GS59-69) for moderate control of Fusarium ear blight (excluding Microdochium nivale) in wheat. Control of ear diseases can result in cleaner, brighter ears.

Leaf Blotch (Rhynchosporium secalis)
Jaunt gives high levels of Rhynchosporium control. Apply Jaunt 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 Jaunt 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.

RESISTANCE
Jaunt contains fluoxastrobin and trifloxystrobin, members of the Qol crossresistance group. Jaunt should be used preventatively and should not be relied on for its curative potential. It should not be
used where disease is already established. Use Jaunt as part of an Integrated Crop Management (ICM) strategy incorporating other methods of control, including where appropriate other fungicides with a different mode of action. You must not apply more than two foliar applications of Qol containing products to any cereal crop.
Limiting the number of sprays is an important factor in delaying the build-up of resistant pathogen populations. There is a significant risk of widespread resistance occurring in Septoria tritici populations in the UK. Failure to follow resistance management action may result in reduced levels of disease control. Appropriate disease risk assessment or decision support systems must be used when deciding whether to treat with Jaunt. Strains of wheat and barley powdery mildew resistant to QoI’s are common in the UK.
The possible development of resistance to Jaunt cannot be predicted. Should it occur Jaunt may not give satisfactory control and no responsibility can be accepted for any loss incurred.

CROP SPECIFIC INFORMATION
Jaunt may be used on all commercial varieties of winter and spring barley, wheat, durum wheat, triticale and rye.
Apply Jaunt at 1.0 litres per hectare in wheat, durum wheat, triticale and rye and 0.8 litres per hectare in winter and spring barley.
The maximum total dose per crop is :- 2.0 litres per hectare in wheat, durum wheat, triticale and rye and 1.6 litre per hectare in winter and spring barley.
Apply Jaunt in 100-300 litres of water per hectare.
The higher spray volumes are recommended where the crop is dense or disease pressure/ risk is high to ensure good penetration to the lower leaves and stem-bases. Disease control may be compromised by reducing water volumes where good spray coverage is difficut to achieve.
A spray pressure of 2-3 bar is recommended. Apply as a MEDIUM spray quality (as defined by BCPC).
Jaunt may be applied at any stage before grain milky ripe stage in wheat, durum wheat, triticale and rye and up to beginning of anthesis (GS 61) in winter and spring barley.

MIXING AND SPRAYING
Thoroughly shake the pack before use.
Add the required quantity of Jaunt 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.
Sprayers should be thoroughly cleaned before 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.
Thoroughly wash equipment with water and detergent after use.
