An emulsifi able concentrate, containing 200 g/l metazachlor and 200 g/l dimethenamid-p, for use as a residual herbicide for the control of a range of broad-leaved and grass weeds in winter oilseed rape.

DIRECTIONS FOR USE

Springbok is a residual herbicide that can be used on all varieties of winter oilseed rape for the control of a range of broad‑leaved and grass weeds.
 
Restrictions/Warnings
When Springbok is applied pre‑emergence, it is important for crop safety to ensure physical separation of the herbicide from the seed. Ensure that the seed is well covered with soil to a depth of 15 mm. With direct‑drilled crops, harrow across the slits to cover the seed before spraying.
Do not disturb the soil after application.
Do not apply to broadcast crops until the crop has attained the two fully expanded cotyledon growth stage.
Do not use Springbok on sands, very light soils or soils containing more than 10% organic matter.
Do not apply to stony soils; i.e. stones, flints or chalk readily visible on surface. On brashy and stony soils, Springbok may cause some reduction in crop vigour and/or plant stand.
Do not apply to cloddy seedbeds. Seedbeds must have a fine, firm tilth for optimum weed control. Loose or cloddy seedbeds must be consolidated prior to application.
Do not apply when heavy rain is forecast and do not use on waterlogged soil or soils prone to waterlogging. Crop thinning or reductions in crop vigour can occur if there is very wet weather after application.
Soil moisture is required for effective weed control via root uptake. Residual control may be reduced under prolonged dry conditions.
Weeds germinating from depth may not be controlled.
Do not apply Springbok to crops suffering from stress, which may be caused, for example, by pests, disease, waterlogging, poor seedbed conditions or previous chemical treatment.
Under frosty conditions a transient scorch may occur.
Avoid spray drift on to neighbouring crops and plants outside the target area.
To reduce the risk of movement of Springbok to water:-
a. On clay soils, create a fine, consolidated seedbed to slow the downward movement of water.
b. Do not apply Springbok to dry soil. Moist soils have fewer and smaller cracks.
c. Do not apply Springbok if heavy rain is forecast, wait until after the event
 
Weed Control
Springbok is taken up via cotyledons and roots and takes maximum effect before, or shortly after, weed emergence. Optimum results are obtained from applications made to fine, firm and moist seedbeds.

Resistance management
Strains of some annual grasses (e.g. black‑grass, wild‑oats, 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 (WRAG) and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
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. Use products with different modes of action and from different chemical groups in sequence or tank-mix, in conjunction with effective cropping rotation and cultivation techniques. In all cases the recommended rate of use should be adhered to. Follow WRAG guidelines.
Key elements of the resistance management strategy for SPRINGBOK.
 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 sequences of effective herbicides with different modes of action within individual crops, or successive crops.
 For the control of black-grass, always use SPRINGBOK in sequence with other effective graminicides with different modes of action.
Monitor fields regularly and investigate the reasons for any poor control.
 
Crops
Springbok can be used on all varieties of winter oilseed rape.
Time of application
Springbok may be applied pre‑ or post ‑emergence of the crop but for optimm activity application must be pre‑emergence of the weeds.
Extreme care must be taken to avoid spray drift onto non‑crop plants outside the target area.
Pre-crop emergence applications should only be made on medium and heavy soils (as defined by the ADAS Soil Texture (85) System). Pre‑emergence applications should be made before the crop seed chits, which in optimum conditions may occur within 48 hours of drilling.
 DO NOT USE SPRINGBOK pre-crop emergence when any of the following conditions apply:-
 When crop has been broadcast.
 The crop seed has started to germinate (i.e. 48 hours after drilling)
Seed is not covered with 15 mm of soil;
 When heavy rain is forecast;
 Dry, cloddy or open seedbeds;
 Late drilled crops – as a guide these are crops drilled later than the first week in September in Northern England and Scotland and later than mid-September in the rest of the UK;
Stony soils, i.e. stones, flints or chalk are readily visible on the soil surface.
Post-crop emergence applications can be made in the following circumstances:
When the majority of the crop has two fully expanded cotyledons and up to before the seventh true leaf growth stage (GS 17);
On light, medium and heavy soils (as defined by the ADAS Soil Texture (85) System);
 When seedbed conditions are not ideal for pre-emergence use; • When the seed is not covered with 15 mm of soil (as with broadcast crops);
 To light, stony, brashy or gravely soils, particularly if heavy rainfall was forecast for the period following drilling;
 When late-drilled crops are to be treated
Rate of application
Apply 2.5 litres/hectare Springbok in a minimum of 220 litres of water per hectare.

Advisory Information
In field brassicas, optimum results have been obtained pre-emergence of the weed.
Pre-emergence applications of Springbok to direct drilled brassicas may cause damage especially at higher doses.
HDC trials in 2005 and 2006 demonstrated the crop safety of Springbok to cauliflower when applied at 2.5 l/ha 1-2 days post-transplanting. However, this ‘extension of use’ remains at the risk of the user. Springbok should be applied in a minimum water volume of 220 litres water/ha.
Irrigation soon after application may result in crop damage.
A minimum PHI of 32 days must be observed.
 
Mixing and Spraying
Application
Apply as a MEDIUM spray, as defined by BCPC. SPRINGBOK should be applied in a water volume of 200-300 litres per hectare
Mixing
Never prepare more spray solution than is required. SHAKE WELL BEFORE USE. Fill the spray tank three quarters full with water and start the agitation. To ensure thorough mixing of the product, invert the container several times before opening. Add the required quantity of SPRINGBOK to the spray tank while re-circulating. Fill up the tank with water and continue agitation until spraying is completed. On emptying the product 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.
Sprayer cleaning
Thoroughly rinse application equipment three times with water after use.
Following Crops
Any crop can follow normally harvested winter oilseed rape treated with SPRINGBOK. Ploughing is not essential before sowing a following cereal crop, but is required for all other crops.
In the event of crop failure, the following crops may be sown after ploughing to a depth of at least 15 cm:
Redrilling the same autumn: winter wheat (excluding durum) or winter barley;
Redrilling the following spring: cereals (excluding durum wheat), spring oilseed rape, peas and field beans.
