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 Stomp 400 SC 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 Stomp 400 SC 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
Stomp 400 SC 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 75 mm (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 Stomp 400 SC 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 3.2 cm of settled soil (2.5 cm for Peas and
Sunflowers, 5 cm 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 Stomp 400 SC.
Stomp 400 SC should not be used on protected crops, or in greenhouses.

Other Restrictions/Warnings
Before using Stomp 400 SC on crops to be processed please consult your processor.
Concentrated or diluted Stomp 400 SC 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 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 Stomp 400 SC:
- 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 Stomp 400 SC 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.

Following Crops
Following crops after normal harvest
Before Rye grass is drilled after a very dry season, plough or cultivate to at least 15 cm.
If spring crops are to be followed by crops other than cereals plough or cultivate to at least 15 cm.

In the event of crop failure
In the event of crop failure the land must be ploughed or thoroughly cultivated to a minimum depth of 15cm to ensure any residues are evenly dispersed throughout the soil.

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 Stomp 400 SC 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 Stomp 400 SC in 100 – 200 l/ha. For potatoes apply Stomp 400 SC 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.
