DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be carefully read in order to obtain safe and successful use of this product.
RESTRICTIONS
Do not apply to crops under stress or to crops suffering from waterlogging, pest attack, disease, frost or the effects of high diurnal temperature changes. Transient yellowing can occur although crops fully recover.
For winter cereals, seed must be covered by 3 cm of soil and for best results apply to a firm, moist seedbed free of clods.
DO NOT sow field beans or broad beans within 12 months of application.
WEEDS CONTROLLED
GRASSWEEDS CONTROLLED
Susceptible
Annual meadow-grass: Pre-emergence
Rough stalked meadow-grass: Pre-emergence
Loose silky bent: Pre-emergence
Moderately susceptible
Italian rye-grass: Up to 2 true leaves
DEFY used pre-emergence will reduce black-grass populations. It should only be used as part of an appropriate management strategy involving sequences with products of alternative modes of action.
BROAD-LEAVED WEEDS CONTROLLED
Susceptible
Ivy-leaved speedwell: Up to 3 true leaves
Cleavers: Up to 3 true leaves
Black nightshade: Pre-emergence
Chickweed: Up to 3 shoots
Forget-me-not: Pre-emergence
Cranesbill: Pre-emergence
Red dead nettle: Pre-emergence
Field speedwell: Up to 5 true leaves
Green field speedwell: Up to 6 true leaves
Wall speedwell: Pre-emergence
Moderately susceptible
Field pansy: At emergence
Weed Resistance
Strains of some annual grasses (e.g. black-grass, wild-oats, and Italian rye-grass) have developed resistance to a range of herbicides which may lead to poor control from one or more products or mode of action. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
DEFY should only be used for control of herbicide resistant strains of annual grasses as part of an appropriate management strategy, including sequences with herbicides of alternative modes of action.
CROP SPECIFIC INFORMATION
Winter Cereals
DEFY applied pre-emergence may infrequently slow crop emergence. This effect is transient and has been demonstrated not to adversely affect yield.
Potatoes
For control of a wider spectrum of weeds use DEFY in mixture with approved formulations of products containing the active ingredients metribuzin or linuron, only as a pre-emergence application. Please consult company literature for specific product and best use guidelines. Always observe full label restrictions for any tank mix partner.
TIMING
Winter Cereals
DEFY may be used both pre-emergence of the crop, and post-emergence of the crop up to GS21.
Early and Maincrop Potatoes
DEFY may be applied pre-emergence and at emergence of the crop (soil rising over emerging potato shoots). Complete ridge formation before application of DEFY and do not disturb treated soil after application.
RATES OF USE
Winter Cereals, Early and Maincrop Potatoes
5 litres of product per hectare. One application per crop.

MIXING AND SPRAYING
Mixing
Fill the spray tank with half the required volume of clean water and start agitation.
Add the required amount of DEFY and continue agitation whilst adding the rest of the water. Agitate the mixture thoroughly before use and continue agitation during spraying.
For 10 litre packs with ‘anti-glug’ plug only
Unscrew and remove the cap covering the ‘anti-glug plug’. Pierce the plug with a screw driver. Add the required amount of DEFY to the spray tank then replace both caps. Continue agitation whilst adding the rest of the water. Agitate the mixture thoroughly before use and continue agitation during spraying.
Spraying
Apply DEFY in a water volume of 200–400 litres per hectare.
Apply DEFY using a conventional fan nozzle producing a medium spray quality as defined by the British Crop Protection Council. A spray pressure of 2.0–3.0 bars is recommended.
PROTECT FROM FROST.
SHAKE WELL BEFORE USE.
SAFETY PRECAUTIONS
(a) Operator protection
Engineering control of operator exposure must be used where reasonably practicable in addition to the following Personal Protective Equipment:
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS), SUITABLE PROTECTIVE GLOVES AND FACE PROTECTION (FACE SHIELD) when handling the concentrate.
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS), AND SUITABLE PROTECTIVE GLOVES when handling contaminated surfaces.
WEAR SUITABLE PROTECTIVE CLOTHING (COVERALLS) during application.
However, engineering controls may replace personal protective equipment if a COSHH assessment shows they provide an equal or higher standard of protection.
WASH CONCENTRATE from skin or eyes immediately.
WASH HANDS AND EXPOSED SKIN before eating and after work.
WASH ALL PROTECTIVE CLOTHING thoroughly after use, especially the insides of gloves.
(b) Environmental protection
Do not contaminate water with the product or its container. Do not clean application equipment near surface water. Avoid contamination via drains from farmyards and roads.

To protect aquatic organisms respect a buffer zone to surface water bodies. Refer to section on LERAP for buffer zone width.
DO NOT ALLOW DIRECT SPRAY from horizontal boom sprayers to fall within 5 m of the top of the bank of any static or flowing water body, or within 1 m of the top of a ditch which is dry at the time of application. DO NOT ALLOW DIRECT SPRAY from hand-held sprayers to fall within 1 m of the top of the bank of a static or flowing water body. Aim spray away from water.
This product qualifies for inclusion within the Local Environment Risk Assessment for Pesticides (LERAP) scheme. Before each spraying operation from a horizontal boom sprayer, a LERAP must be carried out in accordance with CRD’s published guidance of the statutory buffer zone. The results of the LERAP must be recorded and kept available for three years.
(c) Storage and disposal
KEEP IN ORIGINAL CONTAINER, tightly closed in a safe place.
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 safely.
THE (COSHH) CONTROL OF SUBSTANCES HAZARDOUS TO HEALTH REGULATIONS MAY APPLY TO THE USE OF THIS PRODUCT AT WORK
