RESTRICTIONS
ƒDo not apply OKLAR SX to any crop suffering from stress as a result of drought, water-logging, low temperatures, pest or disease attack, nutrient or lime deficiency, soil compaction or other factors reducing crop growth.
ƒ Do not use OKLAR SX on crops undersown with grasses, clover or other legumes or any other broad-leaved crop. ƒ
Do not apply within seven days of rolling emerged crops ƒ
Refer to ‘Compatibility’ for details on use of OKLAR SX with other ‘ALS inhibiting’ herbicides ƒ
Because some non-target crops are highly sensitive to OKLAR SX, avoid damage by drift onto plants outside the target area, or onto ponds, waterways or ditches. Thorough cleansing of equipment is also very important - see separate section.

 

OKLAR SX is a highly active herbicide with foliar and root activity It is readily translocated within the weed plant, inhibiting growth within hours of application. The time taken for symptoms to appear and death to occur may vary between species. In some weed species, depending on weather conditions, symptoms may not be apparent for up to four weeks. Plants not completely killed are often severely stunted and are much less competitive with the crop. OKLAR SX has a moderate residual life in soil under normal conditions. The residual activity is reduced by high soil temperatures due to increased degradation of the active ingredient. Weed control may also be reduced when soil conditions are very dry. Nevertheless, with adequate soil moisture, susceptible weeds germinating soon after treatment will be controlled. 

 

This product contains flupyrsulfuron methyl which is an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B’. When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered resistant to a herbicide if it survives a correctly applied treatment at the recommended dose. Development of resistance within a weed species can be avoided or delayed by sequencing or tankmixing with suitable products having a different mode of action. A strategy for preventing and managing resistance should be adopted. The Weed Resistance Action Group have produced guidelines and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.

 

OKLAR SX can be used on all varieties of winter wheat, winter oats, winter rye and triticale between the growth stages given below. Under certain climatic, soil and crop conditions some slight chlorosis and stunting of the crop may occur. Crops will quickly recover and there will be no effect on grain yield

 

Apply OKLAR SX at 10 g/ha.

 

Winter wheat: From the 1 leaf stage (GS 11) to before first node detectable (GS 31). Winter oats, winter rye, triticale: From 2 leaf stage to December 31.

 

Only cereals, oilseed rape, field beans, red and white clover or grass may be sown in the year of harvest to succeed a cereal crop treated with OKLAR SX. Where OKLAR SX is applied in tank-mix or sequence with other products, the following-crop advice on the labels of those products must be followed as appropriate.

 

FAILURE In the event of crop failure for any reason, sow only winter wheat or spring wheat, within three months of application of OKLAR SX. Prior to resowing, soil should be ploughed and cultivated to a depth of at least 15 cm. After three months follow the recommendations in “Following crops” section.

 

Apply in 100-400 litres of water per hectare, using suitable equipment to give good cover of the weeds. When crops are thick the higher volume should be used. When applying OKLAR SX, care should be taken not to overlap spray swaths.

 

OKLAR SX can be used on all soil types. On highly alkaline soils (pH > 7.7) the residual activity and subsequent weed control achieved by OKLAR SX is reduced. OKLAR SX is more persistent in soils of low pH.

 

Before using OKLAR SX, make sure that the spraying equipment is clean. OKLAR SX mixes easily with water, but the following mixing procedure should be followed: Half fill the spray tank with water, start the agitation and add the required quantity of OKLAR SX directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.

 

Tank-mix partners must only be used in accordance with their label warnings and restrictions. When using OKLAR SX in a tank-mix, always add OKLAR SX to the spray tank first. OKLAR SX is compatible with the following:

¾ STOMP 400SC

¾ DEFY

¾ CRYSTAL

Consult your supplier before applying in tank-mix with any other product.
