DIRECTIONS FOR USE
 All instructions within this section must be read carefully in order to obtain safe and successful use of this product. Priaxor EC is a systemic fungicide with protectant and systemic properties for use in winter wheat, spring wheat, durum wheat, winter barley, spring barley, triticale, rye and oats. When applied for disease control this product may increase green leaf area retention of wheat, barley, rye and triticale
 
Restrictions/Warnings
Extreme care must be taken to avoid drift onto nearby crops. When applied to barley intended for malting, refer to the rate and latest timing restrictions for fluxapyroxad and pyraclostrobin given by the British Beer and Pub Association. No more than two applications of any QoI fungicide may be made to crops of wheat, barley, oats, rye or triticale. You must not apply more than two foliar applications of products containing complex II inhibitors (SDHIs) to any cereal crop. After spraying, wash out sprayer thoroughly according to manufacturer’s guideline and dispose of washings and clean containers according to DEFRA Code of Practice and local authority guidelines.

Resistance management
Priaxor EC should be used in accordance with the instructions for use for the target diseases at the specific growth stages indicated.
Use Priaxor EC 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.
Priaxor EC contains pyraclostrobin, a member of the QoI cross resistance group.
Priaxor EC should be used preventatively and should not be relied upon for its curative potential.
You must not apply more than two foliar applications of QoI containing products to any cereal crop.
Strains of barley powdery mildew resistant to QoIs are common in the UK.
Priaxor EC contains fluxapyroxad which belongs to the SDHI (carboxamide) complex II inhibitor group of fungicides.
To minimise the risk of resistance occurring, apply a maximum of two SDHI fungicide sprays 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.
For the control of Septoria leaf blotch, Priaxor EC must always be used in mixture with another product recommended for its control, and that contains a fungicide from a different cross resistance group to SDHIs and QoIs and is applied at a dose that will give robust control.
Visit the FRAG-UK website for further advice on resistance management of cereal fungicides.
 
Crops
Priaxor EC is a systemic fungicide with protectant and curative properties for use in winter wheat, spring wheat, durum wheat, winter barley, spring barley, triticale, rye and oats.
Time of Application
Apply Priaxor EC at the start of foliar disease attack. A maximum of two applications can be made up to and including flowering just complete in winter and spring wheat, durum wheat, winter and spring barley, oats and rye and triticale.
Earliest timing for first application: BBCH 25
Earliest timing for second application: BBCH 30
Rate of Application
Apply 1.5 litres of Priaxor EC per hectare in 150 to 300 litres of water per hectare.
Qualified recommendation
Priaxor EC may be applied at 1.5 litres per hectare in 100 litres water per hectare, although efficacy at this reduced volume has not been evaluated. Therefore application at 100 litres water per hectare is at user’s risk with regard to biological efficacy.
 
Following crops
After treating a cereal crop with Priaxor EC, cabbage, carrot, clover, dwarf French beans, field beans, lettuce, maize, oats, oilseed rape, onions, peas, potatoes, ryegrass, sugar beet, sunflowers, barley and wheat may be sown as the following crop. The effect of Priaxor EC on other following crops has not been assessed.
 
Mixing and Spraying
Apply as a MEDIUM spray, as defined by BCPC. Half fill the spray tank with clean water and start the agitation. SHAKE THE CONTAINER WELL before use and pour in the required amount of product. Rinse any empty containers thoroughly and add rinsings to the spray tank. Add the remainder of the water and continue agitation until spraying is completed.
When tank mixes are to be used, each product should be added separately to the spray tank, taking due note of any instructions given as to the order of mixing.
