DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.

RESTRICTIONS
DO NOT use Atlantis WG on crops undersown with grasses, clover or other legumes or any other broadleaved crop.
Only one “ALS inhibiting” herbicide can be applied to the same crop in sequence or in tank mixture with
Atlantis WG. Refer to the table under SEQUENCES & TANK MIXTURES for details.
Atlantis WG must not be applied to any crop suffering from stress as a result of drought, water-logging, pest or disease attack, nutrient deficiency, soil compaction or other factors reducing crop growth.
Because some non-target crops are sensitive to Atlantis WG, extreme care is required to avoid drift onto plants outside the target area, or onto ponds, waterways or ditches.
Do not apply Atlantis WG when rain is imminent. Do not apply during periods of frosty weather.
Store in a safe dry place designated as an agrochemical store.

WEEDS CONTROLLED
This product contains mesosulfuron-methyl and iodosulfuron-methyl which are ALS inhibitors, also classified by the Herbicide Resistance Action Committee as ‘Group B’. Use only as part of a resistance management strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass-weed control. Strains of some annual grasses (e.g. black-grass, wild oats and Italian rye-grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing 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 advisor or product manufacturer.

Atlantis WG is readily translocated within the target weed, inhibiting growth within hours of application. The actual time taken for herbicidal symptoms to appear and death varies between weed species, timing of application and weather conditions. In some cases symptoms may not be apparent for up to 4 weeks.

Optimum grass weed control will be obtained when all grass weeds are emerged at spraying. Weeds germinating after application will not be controlled. Due to the potential for yield loss without prior signs of crop phytotoxicity, avoid use of Atlantis WG to control light infestations of grass weeds. As Atlantis WG is active primarily via foliar uptake good spray coverage of the target weed is essential for optimal efficacy. For optimal activity, apply when weather conditions promote active weed growth. Atlantis WG controls emerged weeds on all soil types. Atlantis WG has a moderate residual life in soil under normal conditions. As residual activity is important for optimal activity, avoid application under very dry conditions on to very dry soil. Residual efficacy will be enhanced where seedbeds are fine and moist. High soil temperatures and cloddy seedbeds may reduce the residual efficacy of Atlantis WG. The presence of enhanced metabolism herbicide resistant populations of Italian rye-grass may lead to unacceptable levels of control. To reduce the risk of developing resistance or where resistance to sulfonylurea herbicides is suspected, applications should be made to young, actively growing weeds. 
Key aspects of the Atlantis WG resistance management strategy are:
ALWAYS follow WRAG guidelines for preventing and managing herbicide resistant grass and broad-leaved weeds.
DO NOT use Atlantis WG as a stand-alone treatment for black-grass, rye-grass or common chickweed. Use only in tank mixture or in sequence with herbicides with non-ALS modes of action.
IDEALLY apply Atlantis WG as early as possible and before GS 31 of grass weeds.
DO NOT use Atlantis WG as the sole means of grass weed or broad-leaved weed control in successive crops.
ALWAYS use grass and broad-leaved weed herbicides with non-ALS modes of action throughout the cropping rotation.
ALWAYS monitor weed control effectiveness and investigate any odd patches of poor grass or broad-leaved weed control. If unexplained contact your agronomist who may consider a resistance test
appropriate.

CROP SPECIFIC INFORMATION
Winter Wheat
Apply via a horizontal boom sprayer at a rate of 0.4 kg/ha. Apply in 100-300 L/ha as a FINE to MEDIUM spray (BCPC category). Use application techniques which ensure good weed coverage and
crop penetration, using flat fan nozzles. Ensure that spray swaths do not overlap. Always use Atlantis WG in mixture with authorised adjuvant Biopower (ADJ:0617) at a rate of 1 L/ha.
Only one application of Atlantis WG should be made to the crop.
For use on all varieties of winter wheat. Apply from the 2 leaf stage (GS12) of the crop up to flag leaf ligule just visible (GS39).

SEQUENCES & TANK-MIXTURES
Only one “ALS inhibiting” herbicide can be applied to the same crop in sequence or in tank mixture with Atlantis WG.
Atlantis WG may be applied to the same crop in sequence or in tank mixture with one of the following “ALS inhibiting” herbicides:
Alias SX, Eagle, Presite SX, Ally Max SX, Finish SX, Ratio SX, Avro SX, Galaxy, Refine Max SX, Barton WG, GF-184, Sekator, Biplay SX, Harmony M SX, Simba SX, Boxer, Headland Sure-Fire Gold, Slalom, Calibre SX, Hiker, Spitfire, Chekker, Hunter, Starane Gold, Chimera SX, Inka SX, Starane Vantage, Cleancrop Mondial, Klaxon*, Starane XL, Concert SX, Klaxon OD**, Traton SX, Dakota, Mozaic SX.
* Up to 50 g/ha Klaxon may be applied with Atlantis WG
** Up to 25 mL/ha Klaxon OD may be applied with Atlantis WG

Atlantis WG may be applied to the same crop in sequence with one of the following “ALS inhibiting” herbicides:
Absolute#, Ductis SX#, Lexus SX#, Bullion#, Exceed SX#, Staka SX#.
# To avoid increased selection of herbicide resistant black-grass, a sequence of Atlantis WG with one of these products is only permitted where the product containing flupyrsulfuron-methyl has been applied in tank-mix with a suitable residual partner e.g. pendimethalin and/or flufenacet based products and before black-grass emergence.

These sequences and tank mixtures must only be applied in accordance with label recommendations for every product in the sequence or tank mixture and only if used in conjunction with a robust non-ALS inhibitor autumn herbicide programme. This is particularly important where both components are applied in the spring. Aside from those listed above, do not use in sequence or tank mixture with any other ALS inhibitors, such as sulfonylureas, unless specifically permitted on the label for either product.
As part of the Herbicide Resistance Management Strategy for Atlantis WG, do not apply Chekker or Sekator in sequence with Atlantis WG for the control of common chickweed in order to avoid increased selection for herbicide resistant individuals.
Do not tank mix with chlorpyrifos. Allow at least 14 days before or after chlorpyrifos treatments.

FOLLOWING CROPS and CROP FAILURE
Only winter wheat, winter barley or winter oilseed rape may be sown in the year of harvest to succeed a winter wheat crop treated with Atlantis WG. Spring wheat, spring barley, spring oilseed rape and sugar beet may be drilled in the spring following harvest of the Atlantis WG treated winter wheat crop. Plough prior to planting crops of  oilseed rape, otherwise crop damage may occur. In the event of crop failure for any reason, sow only winter wheat in the same cropping season as an application of Atlantis WG. Where Atlantis WG is applied in sequence or tank mixture with other permitted “ALS inhibiting” herbicides, always follow the most restrictive label with regard to following crops.

MIXING
Add the recommended quantity of Atlantis WG to the spray tank half-filled with the required quantity of clean water. Add the remainder of the water with the sprayer agitation system in operation.
Maintain agitation during mixing and loading and until spraying is complete. Do not leave the sprayer standing with chemical in it. To avoid subsequent damage to crops other than winter wheat it is
important that the spray tank, boom, hoses, filters and nozzles are thoroughly washed out to remove all traces of Atlantis WG immediately after spraying using a proprietary sprayer cleaner (e.g. All Clear Extra) according to the label instructions for that product.
