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
GROPPER SX, alone or in tank-mix, must not be applied to any crop suffering from stress as a result of drought, waterlogging, low temperatures, pest or disease attack, nutrient or lime deficiency or other factors reducing crop growth.
Do not use GROPPER SX on cereal crops undersown with grasses, clover or other legumes or any other broad-leaved crop.
GROPPER SX must not be tank-mixed with chlorpyrifos. Allow at least 14 days between application of GROPPER SX and chlorpyrifos treatments.
When using tank-mixtures take care not to overlap spray swaths.
Do not use GROPPER SX in tank-mix on oats, triticale and linseed. On Linseed allow at least 7 days between GROPPER SX and other treatments (10 days if crop is growing poorly or under stress).
GROPPER SX should not be applied within 7 days of rolling any crop.
Contract agents should be consulted before using on crops grown for seed.
Due to the high level of activity of the herbicide, special care must be taken to avoid damage by drift onto broad-leaved plants outside the target area, or onto ponds,
waterways or ditches. Thorough cleansing of equipment is also very important - see ‘Spray-tank cleanout’
Following Crops - see under "CROPS"
Crop Failure - In the event of crop failure for any reason, sow only wheat within 3 months of the application of GROPPER SX
Refer to ‘Compatibility’ for details on use of GROPPER SX with other ‘ALS inhibiting’ herbicides.

Soil
GROPPER SX can be used on all soil types.

Volume and application
Apply in 100 - 400 litres of water per hectare, using suitable equipment to give good spray cover of the weeds. The higher volume is recommended when crops are thick or weed
growth dense. When applying GROPPER SX, care should be taken not to overlap spray swaths.

Mixing
Before using GROPPER SX, make sure that the spraying equipment is clean.
When using GROPPER SX in a tank-mix, always add GROPPER SX to the spray tank first.

GROPPER SX mixes easily with water, but the following mixing procedure should be followed: quarter fill the spray tank with water, start the agitation and add the required quantity of GROPPER SX directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.

CROPS
CEREALS
GROPPER SX can be used on all winter and spring varieties of wheat, oats, barley and triticale. GROPPER SX must only be applied from 1 February, provided the crop has at least two leaves (wheat, oats and triticale) or three leaves (barley), until before the flag leaf extending stage.

Dose
Apply GROPPER SX at 30 g/ha when used alone or in tank-mix with other herbicides. Following Crops Only cereals, oilseed rape, field beans or grass may be sown in the same calendar year to succeed a cereal crop treated with GROPPER SX.

LINSEED
GROPPER SX should be applied to actively growing linseed (all varieties) from the growth stage "first pair of true leaves unfolded", up to 30 cm high or before flower buds visible,
whichever comes first. Most annual weeds are best controlled by the earliest application possible.

Dose
Apply GROPPER SX at 30 g/ha.

Following Crops
Only cereals should be planted within 16 months of applying GROPPER SX to a linseed crop.

GREEN COVER ON LAND TEMPORARILY REMOVED FROM PRODUCTION e.g. SET-ASIDE
GROPPER SX may be applied to areas temporarily removed from production where the
green cover is made up predominantly (i.e. sufficient to maintain reasonable cover) of grassland, wheat, barley, oats or triticale. Where established grass species are the main cover crop, some discoloration and stunting may occur. GROPPER SX is selective to seedling cereals from the three-leaf stage (GS13) but should not be used on seedling grasses.

Dose and timing
Apply GROPPER SX at 30 g/ha in 100 - 400 litres of water/ha before 1 August in year of application. The higher volume is recommended when weed growth is dense. Only one application of a sulfonylurea-containing product must be made per calendar year to green cover on land temporarily removed from production.

Following crops
Sow only cereals within 16 months of applying GROPPER SX on green cover on land temporarily removed from production e.g. set-aside.
