FORMULATION & ACTIVE INGREDIENT: TOUCHDOWN QUATTRO is an aqueous concentrate containing 360 g/litre glyphosate, a surfactant and water conditioning system.

TARGETS: For the control of a wide range of annual and perennial weeds pre-harvest in Wheat, Barley, Oilseed Rape, Mustards, Linseed, Combining Peas and Field Beans, in stubbles, green cover on land not being used for crop production and natural surfaces not intended to bear vegetation, before drilling or planting any crop, post drilling or planting and crop emergence, for destruction of grassland and for desiccation of Oilseed Rape, Linseed and Mustards.

CONDITIONS FOR OPTIMUM USE
TOUCHDOWN QUATTRO 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.
TOUCHDOWN QUATTRO is quickly deactivated and degraded in soil. Once a sufficient interval for translocation into the weeds has elapsed (as specified below), any crop can be safely drilled or planted. A slight growth check may occasionally be seen, particularly where herbicide traces remain in decaying trash from previously treated crops or weeds. Disperse or bury such decaying matter by thorough cultivation.
To allow TOUCHDOWN QUATTRO to translocate to maximum effect, it is important that perennial weeds are not broken up before treatment, so do not cultivate before spraying. In order to allow full translocation of TOUCHDOWN QUATTRO, do not apply other pesticides, lime, fertilizer or farmyard manure either before or within 5 days after application of this product.
Extreme care should 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 TOUCHDOWN QUATTRO 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. For best results, TOUCHDOWN QUATTRO should be applied to a dry target.

WEEDS CONTROLLED
Optimum control of weeds
For best control, apply TOUCHDOWN QUATTRO 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 (marked #), 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.
The TOUCHDOWN QUATTRO formulation has been fully optimised such that additional tank mix adjuvants are not required when applying at minimum rates recommended on this label.
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 and copies are available from the HGCA, CPA, your distributor, crop advisor or product manufacturer.

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.

MIXING AND SPRAYING
Conventional hydraulic sprayers
Apply through a well maintained conventional hydraulic sprayer as a MEDIUM or COARSE spray. Ensure that the sprayer is correctly calibrated before use. Do not leave the spray liquid in the sprayer for long periods (i.e. during meals or overnight).
Ensure that the sprayer boom is adjusted in height so that the spray pattern gives good, even cover. When applying pre-harvest, a high clearance boom may be necessary, and a narrow-wheeled tractor with crop dividers and a wide boom sprayer will minimise crop damage.
Mixing: Ensure that the sprayer is clean and correctly set to give an even application at the required volume. Half-fill the spray tank with clean water and start agitation. Shake the container and add the required amount of TOUCHDOWN QUATTRO to the sprayer using a filling device (e.g. induction bowl or closed transfer unit) or by direct addition to the sprayer tank. Wash out containers thoroughly, preferably using an integrated pressure rinsing device, or manually rinse three times. Add washings to the sprayer at the time of filling. Top-up the tank with water to the required level.
