FORMULATION & ACTIVE INGREDIENT:CONCORDE is an emulsifiable concentrate containing 150 g/l cyprodinil and 62.5 g/l isopyrazam.

TARGETS:
For the control of Net blotch and Rhynchosporium secalis in winter and spring barley.

RAINFASTNESS:
1 hour.

GENERAL INFORMATION

Isopyrazam is an orthosubstituted pyrazole carboxamide fungicide belonging to the sub-class of the benzonorbornenes. Cyprodinil is from the pyrimidinamine group of chemicals. CONCORDE is predominantly protectant but has significant biochemical potency and can deliver disease control away from the point of application.
 
DISEASES CONTROLLED
Winter and Spring Barley
Net blotch (Pyrenophora teres)
Leaf blotch (Rhynchosporium secalis)
 
RESISTANCE MANAGEMENT
Use CONCORDE 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 an SDH inhibitor to any cereal crop. Disease control may be reduced if strains of pathogens less sensitive to CONCORDE develop. Users should refer to current FRAG-UK guidelines for SDHI compounds.

CROP SPECIFIC INFORMATION

Crops and growing conditions
CONCORDE can be used on all varieties of winter and spring barley. Apply CONCORDE 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.

Rates of use
Apply CONCORDE at 2.0 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 CONCORDE 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 CONCORDE 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 CONCORDE in a recommended 150-300 litres of water per hectare through conventional crop spraying equipment.

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.
