FORMULATION
A capsule suspension containing 360 g/L (30.5% w/w) clomazone.

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 to broadcast crops. Do not use on compacted soils or soils with poor structure which may then be liable to water logging. Do not use BLANCO on sands or very light soils. Do not use on soils with more than 10% organicmatter. Ensure seed is covered by a minimum of 20 mm of soil.
Some transient crop bleaching can occur under certain climatic conditions and can be severe if heavy rainfall follows application. This transientcrop effect is rapidly outgrown and usually has no effect on crop yield. In prolonged, dry periods following application or if applications are made to dry, cloddy seed beds, reduced levels of weed control may occur.
Do not overlap spray swaths. Severe crop damage may occur on field beans. Where damage does occur, this is generally transient and should not affect crop yield.
Extreme care must be taken to avoid spray drift onto non-crop plants outside of the target area. Spring and winter oilseed rape – chlorotic symptoms may be evident at the early establishment phase of the crop from the cotyledon stage up to early stem extension (GS 10-32) with no permanent etrimental effect on crop health or development.
The safety of BLANCO to potato daughter tubers has not been tested - consult the manufacturer or your advisor before using on seed crops.

CONSULT PROCESSORS BEFORE USING ON CROPSFOR PROCESSING.

Contract agents should be consulted before using on crops grown for seed. There is a risk to adjacent crops and non-crop vegetation from the volatilisation of BLANCO. This may result in damage/bleaching to neighbouring vegetation. If effects are seen they must be reported to your crop protection distributor or adviser.
The risk emanating from volatilisation has been addressed via a stewardship campaign and a user education program, the details of which have been reviewed and agreed by CRD.

RESISTANCE

BLANCO contains clomazone, a Group F3 herbicide based on the mode of action classification system of the Herbicide Resistance Action Committee. Repeated use of herbicides with the same mode of action can increase the risk of strains of weeds developing resistance to these compounds, leading to poor control. In order to minimise the risk, a strategy for preventing and managing such resistance should be adopted.
Growers are advised to apply products containing herbicides with different modes of action in sequence or tank-mix where two or more components are active against the target weeds.
Use the recommended rate of BLANCO and the correct application timing. The above should be used in conjunction with effective cropping rotationnd cultivation techniques e.g. stale seedbed, cultivation and use of non-selective herbicide prior to drilling.

Further guidance on weed resistance management is available from the Herbicide Resistance Action Committee (HRAC) and Weed Resistance Action Group (WRAG). Follow WRAG Guidelines.

WEEDS CONTROLLED

For optimum efficacy seedbeds should be firm, level and free of clods, loose and puffy seedbeds should be consolidated before spraying. The following weeds are controlled when BLANCO is applied pre-emergence to a moist, firm seedbed free from clods.

Winter oilseed rape and winter field beans - 0.33 L/ha
Pre-emergence application - susceptible
Cleavers
Common chickweed#
Common field speedwell
Field forget-me-not
Red dead-nettle
Scentless mayweed#
Shepherd’s purse
# Moderately susceptible in winter field beans.
Season-long control of weeds may not occur.


Spring oilseed rape, spring field beans, combining peas, vining peas and potatoes - 0.25 L/ha
Pre-emergence application - susceptible
Cleavers~
Common chickweed~
Common field speedwell

CROP SPECIFIC INFORMATION
BLANCO can be used on all varieties of winter and spring oilseed rape, winter and spring beans, combining peas, vining peas and potatoes. It is important for crop safety, that the seed is covered by a minimum of 20 mm of soil. Direct drilled crops should be harrowed across slits to cover the seed before spraying. Where direct drilled crops are treated, then ploughing and cultivating to a depth of 15 cm must take place before the planting of any subsequent crop. 

TIMING
Winter and spring oilseed rape, winter and spring beans, combining peas and vining peas.
BLANCO should be applied as soon as possible following sowing of the crop and before emergence of both the crop and target weeds.

Potatoes
BLANCO should be applied following the last ridging and before soil cracking (i.e. approximately 7 days before expected potato emergence).

RATE OF USE
Winter oilseed rape and winter field beans - 0.33 L/ha
Spring oilseed rape, spring field beans, combining peas, vining peas and potatoes - 0.25 L/ha.

WATER VOLUME AND SPRAY QUALITY
Apply at in 150-300 L water/ha as a COARSE spray as defined by BCPC.

FOLLOWING CROPS
Autumn treated crops
Following normal harvest of an autumn treated crop, cereals, oilseed rape, field beans, combining peas, potatoes, maize, turnip, linseed and sugar beet may be sown. Prior to planting, soil should be ploughed and cultivated to a minimum depth of 15 cm.

Spring treated crops
Following normal harvest of a spring treated crop, cereals, oilseed rape, field beans, combining peas, potatoes, maize, turnip, linseed and sugar beet may
be sown. Prior to planting, soil should be ploughed and cultivated to a minimum depth of 15 cm.

CROP FAILURE
Autumn treated crops
In the autumn following crop failure, for any reason, only winter cereals and winter beans may be sown, provided at least six weeks has elapsed since application. In the spring following crop failure only spring cereals, combining peas, field beans, potatoes, maize, turnip, onion, carrots and linseed may be sown.
Prior to re-sowing spring cereals, maize, turnip, onion, carrots and linseed, a period of at least 7 months should have elapsed since application.
Prior to re-sowing combining peas, field beans and potatoes a period of at least 6 weeks should have elapsed since application.
Prior to re-sowing any of the listed replacement crops, soil should be ploughed and cultivated to a minimum depth of 25 cm.

Spring treated crops
In the spring following crop failure, only combining peas, field beans, potatoes, maize, dwarf French beans, carrots, turnip, sugar beet, onion, and
linseed may be sown.
Prior to re-sowing combining peas, field beans, potatoes, carrots, turnip, sugar beet, onion and linseed a period of at least six weeks should have elapsed since application. Prior to re-sowing maize and dwarf French beans a period of at least nine weeks should have elapsed since application.
For all spring replacement crops, soil should be ploughed and cultivated to a minimum depth of 25 cm.

MIXING AND SPRAYING
Shake well before use. Half-fill the spray tank with clean water and begin agitation. Add the required quantity of BLANCO and add theremainder of the water.
Rinse empty containers thoroughly and add rinsings to the spray tank. Once the spray solution has been prepared for use it should be used immediately and not left standing in the spray tank. Wash out sprayer thoroughly after use. Crops should not be re-entered until spray residues are dry.

If tank rinse nozzles are fitted: Add clean water to the spray tank until it is approximately a quarter (25%) full then mix in a cleaning agent recommended for sprayer decontamination at the correct dilution rate for the volume of liquid in the spray tank. No further water needs to be added.
Use the tank rinsing nozzles and recirculate for 2 minutes and spray out as described in Disposal of Washings (below).

If tank rinse nozzles are not fitted: Add clean water to the spray tank until it is approximately a quarter (25%) full then mix in a cleaning agent recommended for sprayer decontamination at the correct dilution rate for the full volume of liquid in the spray tank. Fill the sprayer tank to the brim and then re-circulate for 2 minutes and spray out as described in Disposal of Washings (below).

Disposal of Washings
Spray equipment should not be drained or flushed onto land planted with or intended for planting with trees or crops other than oilseed rape,potatoes, beans and peas.
