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.

WEED RESISTANCE
Strains of some annual grasses (e.g. blackgrass, wild oats, and Italian ryegrass) have developed resistance to a range of herbicides which may lead to poor control from one or more product 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 AHDB, CPA, your distributor, crop adviser or product manufacturer.
SPINNAKER® 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 and the use of cultural techniques.

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 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. 

CROP SPECIFIC INFORMATION

Winter cereals
SPINNAKER 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 SPINNAKER in mixture with either RETRO or approved formulations of products containing the active ingredient metribuzin, 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.

Time of application
Winter cereals
SPINNAKER can either be used at pre-emergence of the crop (5 L/ha) or at post-emergence of the crop up to GS 21 (3 L/ha). One application per crop. Early and maincrop potatoes SPINNAKER may be applied pre-emergence, or at emergence of the crop (soil rising over emerging potato shoots). Complete ridge formation before application of SPINNAKER and do not disturb treated soil after application.

RATES OF USE
Winter cereals pre-emergence 5 litres of product per hectare. One application per crop.

Winter cereals early post-emergence up to GS 21 3 litres of product per hectare. One application per crop. Early and maincrop potatoes up to GS 11 5 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. The following crops may be sown in the spring after winter cereal crop failure.

MIXING AND SPRAYING

Mixing
Fill the spray tank with half the required volume of clean water and start agitation. Add the required amount of SPINNAKER to the spray tank and continue agitation whilst adding the rest of the water. Agitate the mixture thoroughly before use and continue agitation during spraying.

Spraying
Apply SPINNAKER in a water volume of 200-400 litres per hectare. Apply SPINNAKER 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 bar is recommended.
SPINNAKER is rainfast after 1 hour. Crops should not be re-entered until spray residues are dry.

Washing out procedure
Immediately after use, clean the spray equipment thoroughly. Drain the system completely and rinse spray tank, boom and nozzles two to three times with clean water until the foam and all traces of product have been removed.
