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 apply ‘Staka 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.
Do not use ‘Staka SX’ on crops undersown with grasses, clover or other legumes or any other broad-leaved crop.
Do not apply within seven days of rolling emerged winter wheat.
Refer to ‘Compatibility’ for details on use of Staka SX with other ‘ALS inhibiting’ herbicides.
Because some non-target crops are highly sensitive to ‘Staka 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.

CROPS
‘Staka SX’ can be used on all varieties of winter wheat, winter barley, 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.

FOLLOWING CROPS
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 ‘Staka SX’. Where ‘Staka 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.

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

VOLUME AND APPLICATION
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
‘Staka SX’, care should be taken not to overlap spray swaths.

Use rates

Winter wheat: Up to 20g/ha in tank-mixture pre or post-emergence.
Winter barley: Up to 20g/ha in tank-mixture pre-emergence only.
Winter oats, Winter rye and Triticale: 10g/ha alone or in tank-mixture post-emergence only

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

MIXING
Before using ‘Staka SX’, make sure that the spraying equipment is clean. ‘Staka 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 ‘Staka SX’ directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.
