Restrictions/Warnings
Avoid spray drift on to neighbouring crops.
This product may cause damage to broad-leaved plant species.

Crops
Chord is a fungicide for use in winter wheat, spring wheat, durum wheat, winter barley, spring barley, oats, rye and triticale.
Time of Application
Apply Chord at the start of foliar or stem based disease attack. A maximum of two applications can be made up to and including flowering (anthesis) just complete (GS69) in winter and spring wheat, durum wheat, rye and triticale, and up to and including emergence of ear just complete (GS59) in winter and spring barley and oats.
For protection against Fusarium ear blight and sooty mould on the ears of winter and spring wheat and durum wheat, apply Chord during ear emergence.
Rate of Application
Apply 1.5 litres Chord in a minimum of 200 to 300 litres of water per hectare.
Qualified recommendation
Chord may be applied at 1.5 litres per hectare in 100 litres of water per hectare although efficacy at this reduced volume has not been evaluated. Therefore application at 100 litres of water per hectare is at user‘s risk with regard to biological efficacy. Reducing the water volume is not recommended where control of stem base diseases is required.
 
Resistance Management
Use Chord 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.
Chord 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.
Chord contains boscalid which belongs to the SDHI (carboxamide) group of fungicides. To minimise the risk of resistance occurring, apply a maximum of two SDHI fungicides per cereal crop
Following crops
After treating a cereal crop with Chord, onions, oats, sugar beet, oilseed rape, cabbages, carrots, sunflowers, barley, lettuce, ryegrass, dwarf French beans, peas, potatoes, clover, wheat, field beans and maize may be sown as the following crop.
Mixing and Spraying
Never prepare more spray solution than is required.
Three quarters fill the tank with clean water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of Chord to the spray tank while re-circulating. Add the remainder of the water and continue agitation until spraying is completed.
When tank mixes are to be used, take due note of any instructions given as to the order of mixing. Each product should be added separately to the spray tank and fully dispersed before the addition of any further product(s).
All tank mixes should be used immediately after mixing.
On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely.
