Suspension Concentrate (SC) containing 500 g/l (44.1 % w/w) ethofumesate. Also contains 1,2-ethanediol. For the control of annual grasses and broad-leaved weeds in sugar beet, red beet, fodder beet and mangels and in grassland for seed production.

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.’
Ethofumesate is a benzofuran herbicide for control of annual grasses and broad-leaved weeds
OBLIX 500 can be used pre- or post- crop emergence in sugar beet, red beet, fodder beet and mangels, including seed crops. OBLIX 500 must be used in combination with other products based on chloridazon or lenacil (pre-emergence) or phenmedipham (post-emergence), as listed in the sections ‘Crop specific information’ and ‘Compatibility’
The product can also be used in established grassland swards of perennial ryegrass and tall fescue grown for seed production. It must not be used on grassland for agricultural use or animal consumption.
Applications of OBLIX 500 can be made as an overall or a band spray.

RESTRICTIONS
OBLIX 500 can be used on light soils and those with organic matter at or below 5 %. On medium soils persistence and residual control may be reduced and/or weed control may be less than the listed susceptibilities.
Avoid drift to areas outside those being sprayed having due regard to the prevailing weather conditions and spray quality being used.
Do not treat when frost is expected within the next 7 days, as this may cause irreversible damage to the crops.
Do not treat red beet with OBLIX 500 in combination with chloridazon.
Do not use when crop is under stress, e.g. from the use of other pesticides, wind damage, lime deficiency, nutrient deficiencies, insect or fungal attack etc., as this may cause irreversible damage to the crop
Do not spray under high light intensity or temperatures (> 21 °C). In this case delay application until the evening.
Consult processors before using on red beet grown for processing.
This product must not be used on grassland where treated grass may be consumed by livestock (either by direct grazing or consumption of grass cuttings)

CROP SPECIFIC INFORMATION
A. SUGAR BEET, RED BEET, FODDER BEET AND MANGELS
1. PRE-EMERGENCE APPLICATIONS On light soils OBLIX 500 must be used preemergence in combination with approved formulations of chloridazon or lenacil, as specified in the section ‘Compatibility’ and as shown below. On medium soils 2.0 litres/ha OBLIX 500 can be used in mixture with either chloridazon* or lenacil*, as shown below.
On medium soils persistence and residual control may be reduced and/or weed control may be less than the listed susceptibilities. Apply OBLIX 500 to a fine, preferably moist, firm level seed bed.
Timing: At or as soon as possible after drilling, but before emergence of crop and weeds.
Only one pre-emergence application with OBLIX 500 can be made

2. POST-EMERGENCE APPLICATIONS
Where no pre-emergence application with products based on ethofumesate is made, OBLIX 500 can be applied post-emergence in combination with approved formulations of phenmedipham (see ‘Compatibility’ section for further information on this combination).
This will give control of fat hen up to the two true leaf stage and wild pansy at the cotyledon stage.
OBLIX 500 should be used as a split application at reduced doses.

Split treatment – two applications, in combination with phenmedipham:
Dose: 0.6 litres/ha OBLIX 500 + 2.5 litres/ha phenmedipham
Timing: When the beet have at least 2 fully expanded leaves. Allow at least 15 days between applications.

B. GRASSLAND (seed crops)
OBLIX 500 controls shepherd’s purse, common chickweed and annual meadow grass in established grassland of perennial ryegrass (Lolium perenne) and tall fescue (Festuca arundinacea) grown for seed cultivation.
Dose: 2 L/ha
Timing:
OBLIX 500 may be sprayed in established grassland grown for seed production when the grass has started to regrow or the grass has hardened after cutting. Apply after the harvest of any cover crop. Do not repeat the treatment. Spray onto a healthy crop only.
Best results are obtained if OBLIX 500 is applied to a vigorous competitive crop where some growth is occurring in moist soil and when further rain falls within 10 days of spraying. The crop and weeds must be at the correct stage when sprayed. This is normally between mid-October and mid-December.
Applications may be made up to the end of February in Avon, Berkshire, Cornwall, Devon, Dorset, Gloucestershire, Hampshire, Kent, Oxfordshire, Somerset, Surrey, Sussex and Wiltshire, up to the end of March in the remainder of England, Wales and Northern Ireland and up to mid-April in Scotland. Common chickweed will be controlled by applications up to mid-April in all regions provided rapid growth has not started and application ensures that a reasonably high proportion of the spray reaches the soil.
Any clover present will be killed or severely checked. Do not overlap spray swaths. No guarantee is given that certification of seed will be obtained after using OBLIX 500.

RESISTANCE WARNING
Strains of some annual grasses (e.g. black-grass, wildoats, and Italian rye-grass) have developed resistance to herbicides which may lead to poor control. 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 HGCA, CPA, your distributor, crop adviser or product manufacturer.

FOLLOWING CROPS
After ploughing (mould board) to a minimum depth of 15 cm, any crop may be sown 3 months after applying combinations with OBLIX 500 at the doses recommended on this label.

MIXING AND SPRAYING
Overall spray:
Apply in 200-240 litres water per hectare as a COARSE (pre-emergence applications only) or MEDIUM quality spray (BCPC classification).
Band spray:
The application rate for band spraying is as mentioned in the section ‘Crop specific information’, but the area treated by these application rates is dependent on the row spacing and the band width.
Apply in 240 litres water per ha as a MEDIUM quality spray (BCPC classification), using nozzles suitable for this application (consult manufacturers’ instructions where necessary).
For an 18 cm band and a water volume of 240 litres water per ha, flat fan nozzles with a fan angle of 80 ° and an output of 0.4 litre per minute at 3 bar can be used.
Check and clean all hoses, nozzles and equipment to be used prior to use. Half fill the sprayer tank with clean water and begin agitation. Add the required quantity of the mixing partner, followed by the required quantity of OBLIX 500. Fill the spray tank with water as required whilst agitating. Continue agitating during spraying
The time between preparing the spray liquid and using it on the field should be as short as possible, as crystallisation of the phenmedipham product may occur.
When spraying take care to avoid drift onto neighbouring crops, buildings or non-target plants
