Touchdown System 4, 5 litres

The product was withdrawn due to the expiration of the validity of the approval certificate as of 20.08.2018.

CONDITIONS FOR OPTIMUM USE

TOUCHDOWN applied to foliage is translocated throughout the plant, controlling all parts including roots, rhizomes or stolons. After treatment, discolouration of the leaves is seen first on grass weeds but takes longer to appear on broad-leaved weeds. The time for complete kill of weeds depends on species and growing conditions, and may vary from a few days to a few weeks.

It is quickly deactivated and degraded in soil. Once a sufficient interval for translocation into the weeds has elapsed,any crop can be safely drilled or planted. To allow this product to translocate to maximum effect, it is important that perennial weeds are not broken up before treatment, so do not cultivate before spraying. 
This product, do not apply other pesticides, lime, fertilizer or farmyard manure either before or within 5 days after application of this product. Extreme care must be taken to avoid spray drift as this can severely damage neighbouring crops or non crop plants outside the target area. Do not spray in windy weather, especially if applying a spray with smaller droplet size.

In good growing conditions it is rainfast within 6 hours. Where weed growth and uptake is slowed by adverse conditions, a rain-free period of up to 24 hours following spraying may be necessary.

WEEDS CONTROLLED
For best control, apply it to weeds which are actively growing, with enough leaf to absorb the product. Weeds are less susceptible to this product when growth is restricted by natural senescence or by factors such as drought, waterlogging, frost or high temperature. Such conditions at, or soon after, spraying may result in reduced control.
Where a range of dose rates is given for control of Common Couch, the full rate of 4.0 litres per hectare will give the best and most reliable control. Rates may be reduced within the range indicated where weed growth is suitable and in good growing conditions. Reduced rates may give less than optimum levels of control, and should only be used where such control may be tolerated, as in the case of maintenance control of lower weed populations.
Strains of some annual grasses (e.g. 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.

TIMING FOR OPTIMUM CONTROL OF WEEDS
Common Couch and other perennial grass weeds
Treat only when a full emergence of actively growing green leaf is reached. Common Couch reaches this susceptible stage of growth from the beginning of tillering and new rhizome growth, usually when plants have 4 or 5 leaves with at least 10 cm of new growth.
Perennial broad-leaved weeds
Best treated when actively growing and at or near flowering, but before senescence begins.
Annual weeds
Must be actively growing, with sufficient leaf area for uptake of the spray. Annual grasses should have at least 5 cm of leaf and annual broad-leaved weeds at least 2 expanded true leaves before spraying. Annual weeds emerging after treatment will not be controlled. 

APPLICATION
Apply TOUCHDOWN pre-harvest in the following water volumes:
Wheat, barley, linseed, combining peas and field beans: 80 to 250 litres per hectare
Oilseed rape and mustards: 200 to 250 litres per hectare 200 to 250 litres per hectare is the preferred volume where crop or weeds are dense and good coverage is necessary.
