FORMULATION & ACTIVE INGREDIENT: SEGURIS is a suspension concentrate containing 90 g/l epoxiconazole (8.4% w/w) and 125 g/l isopyrazam (11.7% w/w).

Control of Brown rust and Yellow rust and moderate control of Mycosphaerella graminicola and Phaeosphaeria nodorum in winter and spring wheat. Control of Brown rust, moderate control of Ramularia collo-cyni and reduction of Net blotch and Rhynchosporium secalis in winter and spring barley. Control of Brown rust and reduction of Rhynchosporium secalis on rye. Control of Brown rust and moderate control of Mycosphaerella graminicola and Phaeosphaeria nodorum on triticale.

RAINFASTNESS: 1 hour

GENERAL INFORMATION
Isopyrazam is an orthosubstituted pyrazole carboxamide fungicide belonging to the sub-class of the benzonorbornenes.
Isopyrazam is an SDH inhibitor (FRAC group #7 carboxamides). Isopyrazam is predominantly protectant but has significant biochemical potency and can deliver disease control away from the point of application.
No cross resistance to any compound of a different fungicide class is expected.
Epoxiconazole is a triazole (DMI) fungicide. Epoxiconazole is a systemic fungicide with protectant and curative properties.
SEGURIS shows good crop safety and disease control which can result in significant yield benefits. Wheat crops may show some transient bleaching after treatment but this is unlikely to have an effect on yield.
SEGURIS is best used as a protectant treatment or in the earliest stages of disease development.

RESISTANCE MANAGEMENT
Use SEGURIS 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 products containing SDH inhibitors to any cereal crop. Users should refer to current FRAG-UK guidelines for SDHI compounds.
SEGURIS 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 DMIs contact your agronomist or specialist advisor, and visit the FRAG-UK website.
Disease control may be reduced if strains of pathogens less sensitive to SEGURIS develop.

CROP SPECIFIC INFORMATION
Crops and growing conditions
SEGURIS can be used on all varieties of winter wheat and winter and spring barley, rye and triticale. Apply SEGURIS under good growing conditions with adequate soil moisture. Avoid poor growing conditions which may give less reliable results.
Timing
Always inspect crops to assess disease development immediately before spraying. Best results will be achieved from applications made as a protectant treatment or in the earliest stages of disease development following a disease risk assessment or the use of appropriate decision support systems.
SEGURIS is accepted by BBPA (British Beer and Pubs Association) for use on malting barley provided application is made before the start of ear emergence. Latest timing in malting barley is, therefore, before the first spikelet of inflorescence is just visible (GS51).
Rates of use
Apply SEGURIS at 1.0 litres per hectare.

FOLLOWING CROPS
There are no restrictions on succeeding crops in a normal rotation.

MIXING AND SPRAYING
Mixing Procedure
Make sure the sprayer is set to give an even application at the correct volume. Fill the spray tank with half the required volume of water and begin agitation. Add the required amount of SEGURIS to the spray tank and allow to disperse before adding any other product. Add the rest of the water and continue to agitate the mixture thoroughly. Always agitate during spraying.
Spray Quality
Apply SEGURIS using a conventional fan nozzle producing a medium spray quality as defined by the British Crop Protection Council. A spray pressure of 2-3 bars is recommended.
Spray Volume
Apply SEGURIS in a recommended 100-400 litres of water per hectare through conventional crop spraying equipment. 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 maybe compromised by reducing water volumes, where good spray coverage is difficult to achieve.
After Spraying
Thoroughly wash out sprayer according to manufacturer’s guidelines and dispose of washings and clean containers according to DEFRA Code of Practice and local water authority guidelines.
