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. A herbicide for the control of annual-grass and broad-leaved weeds in a wide range of crops.
 
Restrictions/Warnings
Efficacy
Some soil moisture must be present for Claymore to be activated.Best results will be obtained if rainfall occurs within seven days of application.
Residual control may be reduced:
- under prolonged dry conditions
- on soils with a high Kd factor
- where organic matter exceeds 6%
- where ash content is high
Do not disturb the soil after Claymore has been applied as this will result in reduced weed control.
Where cultural techniques which encourage the build up of organic residues in the surface soil are practised for a number of seasons, the effectiveness of residual herbicides may be reduced. In such circumstances periodic ploughing is recommended to disperse residues into a greater volume of soil.
Soil types
Claymore may be used on all mineral soil types.
Do not use on soils with more than 10% organic matter.
On stony or gravely soils there is a risk of crop damage, especially if heavy rain falls soon after application.
Do not use on water logged soil or soils prone to water logging.
Seedbed preparation
Trash and straw should be incorporated evenly during seedbed preparation. Seedbed must have a fine, firm tilth. Consolidate loose or cloddy seedbeds before use. Following pre-emergence applications, unconsolidated clods (especially if larger than 75mm (3“) diameter) may reduce the level of weed control and cause seed to be inadequately covered, which could result in crop damage.
Crop safety
Extreme care should be taken to avoid damage by drift onto plants outside the target area.
Do not apply Claymore to crops suffering from stress, which may be caused for example by pests, disease, water logging, poor seedbed conditions or previous chemical treatment.
Seed should be covered with a minimum of 3.2cm of settled soil (2.5cm for Peas and Sunflowers, 5cm for Maize).
Shallow drilled crops should be treated post-emergence.
Do not soil incorporate.
Do not spray undersown crops.
Do not undersow crops treated with Claymore.
Claymore should not be used on protected crops, or in greenhouses.
Other Restrictions/Warnings
Before using Claymore on crops to be processed please consult your processor. Concentrated or diluted Claymore will stain. Avoid spillage. Staining is minimised or completely removed if skin and clothes are washed immediately. Hose down machinery immediately after use with a spray tank cleaner.

Resistance management
Strains of some annual grasses (eg Black-grass, Wild-Oats, and Italian Ryegrass) 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.
Populations of Black-grass and Italian ryegrass with high levels of enhanced metabolism resistance will not be fully controlled.
Key elements of the resistance management strategy for Claymore:
- Always follow WRAG guidelines for preventing and managing herbicide resistant weeds.
- Maximise the use of cultural control measures wherever possible (e.g. crop rotation, ploughing, stale seedbeds, delayed drilling, etc).
- Use tank mixes or sequences of effective herbicides with different modes of action within individual crops, or successive crops.
- For the control of herbicide resistant grassweeds, always use Claymore in tank mix or sequence with other effective graminicides with different modes of action.
- Apply pre-emergence of weeds wherever possible. If applications are delayed, apply post-emergence products/mixtures to small, actively growing weeds, especially where high levels of resistance are suspected and to reduce the risk of resistance development.
- Monitor fields regularly and investigate the reasons for any poor control.
 
Crop specific information
Claymore is recommended for use on all varieties of approved crops on any mineral soil except where indicated in the table below.
Winter wheat including Durum wheat, winter barley
Product:          Claymore
Rate :             2.5 or 3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing Pre-emergence of the crop to before leaf sheath erect stage, (GS30). Do not apply pre-emergence to crops drilled after 30th November.
Seed depth :     Seed must be covered with a MINIMUM of 3.2cm of settled soil. ONLY treat shallow drilled crops POST-EMERGENCE.
 
Winter wheat
Claymore applied in tank mix with Atlantis WG
Product: Claymore + Atlantis WG + Biopower
Rate:  3.3 l/ha + 400 g/ha + 0.5%
Water volume:   200 litres/hectare.  
Timing: Apply post-emergence from 2 leaves on the crop.
             Apply to young, actively growing weeds.
             Optimum timing for Black-grass control is 1-3 leaves of the Black-grass.
Notes:  For optimum activity, apply when weather conditions promote active weed growth.Do not apply to crops suffering from stress, which may be caused for example by pests, disease, water logging, poor seedbed conditions or previous  chemical treatment. Under certain climatic, soil and crop conditions some slight chlorosis and stunting of the crop may occur.  If frost is likely, avoid spraying non frost-hardened crop. Avoid spraying during periods of prolonged or severe frost. Control may be reduced if rain falls within 2 hours of application.  Thoroughly clean all spray equipment with a proprietary sprayer cleaner immediately after spraying to avoid subsequent damage to crops other than cereals. Consult Atlantis WG product label for information on sequences with other sulfonylurea or ‘ALS-inhibiting’ herbicides.

Timing:               Pre-emergence of the crop. Apply Claymore as soon as possible after drilling and before emergence. Due to risk of dry soils, do not apply Claymore                                alone after the end of March (mid April in Scotland) unless rainfall is imminent.
Seed depth:        Seed must be covered with a MINIMUM of 3.2cm of settled soil.
 
Combining Peas
Product:          Claymore
Rate:              3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing:           Pre-emergence of the crop. Apply Claymore as soon as possible after sowing and final seedbed preparation. Do not apply if the plumule is less than                                13mm from the soil surface. Due to risk of dry soils, do not apply Claymore alone after the end of March (mid April in Scotland) unless rainfall is imminent.                      Soil types All mineral soils except gravelly soils
Seed depth:     Seed must be covered with a MINIMUM of 2.5cm of settled soil.
 
Potatoes (First early, second early & maincrops)
Product:         Claymore + Sencorex WG
Rate:              3.3 l/ha + 0.5 kg/ha In dry conditions apply a Claymore – Sencorex WG sequence.
Water volume: 200 litres/hectare.
Timing:           Pre-emergence of the crop. Apply as soon as possible after planting and final ridging up. Loose structured ridges must be allowed time for settlement                            before application. Do not apply later than 7 days before emergence.
Soil types:       Do not use on Sands (S), Gravelly or Stony soils.
Variety:           Read the Sencorex WG label carefully, particularly with regard to varietal restrictions.
Application:     Claymore should be applied in a minimum of 200 litres of water/ha.
Notes:            Best weed control will be achieved with settled well-rounded ridges with few clods. If re-ridging is necessary, delay application until after the final ridging                        is completed. Slight distortion and discolouration of the initial shoots may occur if very heavy rain falls after application but before emergence, particularly                      to crops grown on very light soils. This is quickly outgrown and subsequent growth is unaffected. Read the Sencorex WG label carefully, particularly with                        regard to following crop restrictions.
 
Sunflowers
Product:          Claymore
Rate:               3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing:           Apply as soon as possible after sowing and final seedbed cultivation, before crop and weed emergence.
Seedbed:        Consolidate seedbeds after drilling to provide a firm level soil. Seed should be drilled so that after seedbed consolidation it is covered by a minimum of                             2.5cm of settled soil.
 
 
Carrots and Parsnips
Product:         Claymore
Rate:              3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing:           Apply as soon as possible after drilling but before crop and weed emergence.
Notes:            If emerged weeds are present after drilling but pre-emergence of the crop, Claymore may be applied in tank mix with a recommended approved contact                          herbicide.
 
 
 Transplanted Brassicas (Broccoli, Brussels sprouts, Cabbages, Clabrese, Cauliflowers)
Product:          Claymore
Rate:              3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing:           Apply after final plantbed cultivation but before transplanting. Do not apply Claymore post-planting as crop damage may occur. Do not apply Claymore to                       any transplanted brassicas when heavy rain is forecast.
Application:     Do not incorporate and avoid all unnecessary disturbance to soil after application. When transplanting care must be taken not to introduce treated soil into                       the root zone. If necessary, irrigation should be used before application as some moisture is essential for the chemical to be activated.
Soil types:       Do not use on crops grown on sands (CS, S, FS, LCS), very light soils (LS, LFS, CSL), as crop damage may result. Notes If emerged weeds are present at                         pre-transplanting application, apply Claymore in tank mix with a recommended approved contact herbicide.
 
Bulb onions (Spring and autumn drilled or transplanted) and Leeks (drilled only)
Product:         Claymore  
Rate:              3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing:           Drilled crops - apply Claymore as soon as possible after drilling but before crop or weed emergence. Transplanted crops - apply Claymore pre-                                     transplanting. Do not apply Claymore to any onion or leek crop when heavy rain is forecast.
Seed depth:   Seed should be covered with a minimum of 2.5cm of settled soil.
Application:   When transplanting, care must be taken not to introduce treated soil into the root zone.
Soil types:     Claymore is not recommended for use on onions or leeks grown on sands (CS, S, FS, LCS), very light soils (LS, LFS, CSL), as crop damage may result.                           Claymore is not recommended for use on onions or leeks grown on fen soils or other soils containing in excess of 10% organic matter, as weed control may                      be reduced.
Notes:          If weeds are present, these can be controlled by applying Claymore in tank mix with a recommended contact herbicide. Read tank mix partner label                                carefully for restrictions on transplanted multi-seeded onions or leeks.
 
 Forage maize
Product:         Claymore
Rate:              3.75 l/ha
Water volume: 100 to 200 litres/hectare.
Timing:           Pre-emergence to before 4th leaf of the crop.
Notes:             Do not use on Sweetcorn or Maize grown for seed. Seed must be covered by a minimum of 5cm of settled soil. The use of Claymore may affect the full                             development of crown roots which function only to anchor the plant. This has no effect on the yield of maize. If application is followed by a period of dry                         conditions or in situations where very heavy populations occur, a sequence of Claymore and a product applied post-emergence may be necessary.
 
 Strawberries (Maiden and Established crops)
Product:Claymore
Rate: 3.3 l/ha
Water volume: 100 to 200 litres/hectare.
Timing :Maiden Beds: - runners should be planted so that roots are well covered. - good consolidation of the plantbed is necessary for good weed control. - Claymore should be applied to dormant newly planted runners in the autumn or early spring immediately after planting and prior to weed emergence. - if runners are likely to be slow in establishing due to stress conditions, such as drought, at the time of planting, the application of Claymore should be delayed until plants have established and are free of stress. - application made after runners have started growing away may reduce the initial vigour of new foliage but this will be rapidly outgrown. - do not apply Claymore before October to beds newly planted with cold-stored runner or beds newly planted in late summer. - pre-planting application of Claymore is not recommended. Established beds - apply Claymore to weed free soil from autumn to early spring during the dormant period of the crop. - Claymore applied after the end of March or after the emergence of flower trusses in the spring may affect crop yield, particularly if conditions adverse to vigorous plant growth follow application. - do not apply Claymore during the flower initiation period (immediately post-harvest to mid-September).
Notes:Leaf growth of strawberries may be checked following applications of Claymore in the spring but, in extensive experimentation, this has been shown not to affect yield. Do NOT use Claymore on protected crops or crops grown in green houses.

Mixing and Application
Mixing
Never prepare more spray solution than is required.
Half fill the tank with clean water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of Claymore to the spray tank while re-circulating. Fill up the tank with water and continue agitation until spraying is completed.
When tank mixes are to be used, take due note of any instructions given as to the order of mixing. Each product should be added separately to the spray tank and fully dispersed before the addition of any further product(s).
On emptying the container, rinse container thoroughly by using an integrated pressure rinsing device or manually rinsing three times. Add washings to sprayer at time of filling and dispose of container safely.
 Application
Ensure good, even spray cover of the target using a FINE or MEDIUM quality spray, as defined by BCPC. Apply Claymore in 100-200 l/ha. For potatoes apply Claymore in minimum 200 l/ha water. When tank mixing with other products use a minimum water volume of 150-200 l/ha depending on the tank mix partner. When using 100 l/ha include an 80 mesh inline boom filter.
 Sprayer cleaning
After spraying, thoroughly clean and flush out application machinery with a minimum of three rinses, to ensure that all traces of product are removed.
