DIRECTIONS FOR USE
 
DEFY is an emulsifiable concentrate containing 800 g/l prosulfocarb.
 
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.

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 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 either RETRO or 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
5.0 litres of product per hectare. One application per crop.
 
FOLLOWING CROPS
Winter Cereals, Early and maincrop Potatoes
Do not sow field beans or broad beans within 12 months of application.
In the case of winter cereal crop failure, Winter Wheat or Winter Barley may be sown immediately in the autumn.
 
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 and 20 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. A spray pressure of 2–3 bars is recommended.
