PROTECT FROM FROST

Firefly 155 is a mixture of a strobilurin and a triazolinthione fungicide recommended for control of a wide range of diseases on winter and spring wheat, winter and spring oats and winter rye.

CROPS
Firefly 155 may be used on all commercial varieties of winter and spring wheat, winter and spring oats and winter rye.

RATE OF USE
Apply Firefly 155 at:- 1.5 litres per hectare for wheat and winter rye and 1.25 litres per hectare for oats.
The maximum total dose per crop is 3.0 litres per hectare for wheat and rye and 2.5 litres per hectare for oats.

APPLICATION
Water volume
Apply Firefly 155 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 difficult to achieve.

Pressure
A spray pressure of 2-3 bar is recommended.

Spray quality
Apply as a MEDIUM spray quality (as defined by BCPC).

Latest Permitted Timing
Winter and spring wheat and winter rye: Firefly 155 may be applied at any stage before grain milky ripe stage.
Oats: Firefly 155 may be applied at any stage up to beginning of anthesis.

Mixing
Thoroughly shake the pack before use. Add the required quantity of Firefly 155 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.

Tank washing
Any product rinsings should be added to the spray tank and sprayed on the crop to be treated.
The product can be removed from spray tanks by rinsing with water and detergent.

General
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.

DISEASES CONTROLLED
Wheat
Eyespot (reduction of incidence and severity), Septoria leaf and glume blotch, powdery mildew, yellow rust and brown rust.
Rye
Eyespot (reduction of the incidence and severity), powdery mildew, brown rust, Rhynchosporium.
Oats
Eyespot (reduction of the incidence and severity)

APPLICATION TIMING
Eyespot (Oculimacula spp.) reduction of disease incidence and severity.
Spray Firefly 155 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 Firefly 155 at full flag leaf emergence 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.
Firefly 155 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 (Blumaria graminis)*
When used for the control of other diseases, Firefly 155 will also give control of wheat powdery mildew.

Yellow Rust (Puccinia striiformis)
Apply Firefly 155 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)
Apply Firefly 155 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.

Leaf Blotch (Rhynchosporium secalis)
Apply Firefly 155 in spring at the first signs of disease. For severe infections a second application may be necessary 2-3 weeks later.
* Strains of powdery mildew resistant to Qol fungicides are common in the UK. Where specific control measures are required, this should be achieved through a programme of measures including using products with recommendations for control of these diseases with different active substances used in mixture or sequence.

MANAGEMENT STRATEGY TO MINIMISE THE LIKELIHOOD OF RESISTANCE
Apply fungicides according to manufacturer’s recommendations for the target disease (or complex) at the specific crop growth stage indicated. Effective disease management is a critical parameter in
delaying the build-up of resistant pathogen populations. Firefly 155 is a mixture of two fungicides with different modes of action, a strobilurin and a triazolinthione.
Firefly 155 contains fluoxastrobin, a member of the Qol crossresistance group. Firefly 155 should be used preventatively and should not be relied on for its curative potential.
Use Firefly 155 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 QoI-containing products to any cereal crop.
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.
Use of fungicides which have different modes of action have been shown to protect against the development of resistant forms of disease.
A programme of sprays should not include more than 2 sprays of Firefly 155 or any other product that contains a strobilurin fungicide.

CAUTION: The possible development of disease strains resistant to Firefly 155 cannot be excluded or predicted. Where such resistant strains occur, Firefly 155 is unlikely to give satisfactory control.

FACTORS AFFECTING CROP SAFETY
Occasionally, after the application of Firefly 155, some transient leaf chlorosis on wheat may occur, but these symptoms have not been shown to adversely affect yield responses accruing from the benefits of disease control.
