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.

RESTRICTIONS
- DO NOT roll, harrow or cut crops within seven days before or after spraying.
- DO NOT graze crops within a week before or 2 weeks after spraying
- DO NOT apply during cold weather or drought.
- DO NOT apply during rain or if rain is expected.
- DO NOT spray in windy weather and avoid drift onto broad-leaved plants outside the target area. FARMCO UNDERSOWN is active at low concentrations. The following crops are particularly susceptible to spray drift: beet, brassicae (eg turnips, swedes, oilseed rape) and most market garden crops including lettuce and tomatoes under glass, pears and vines.
- DO NOT use FARMCO UNDERSOWN immediately before or after sowing any crop

WEEDS CONTROLLED
FARMCO UNDERSOWN is a selective herbicide for use post-emergence to control of broadleaved weeds in Cereals, Grassland and Lucerne.
FARMCO UNDERSOWN applied at 4.5 L/ha will control those annual weeds as listed and will control perennial weeds as indicated.
Annual weeds will be best controlled if spraying is done while the majority of weeds are seedlings.
Perennial weeds should be sprayed during their period of maximum growth, usually when the flower buds are beginning to form. The response of perennial weeds to treatments are often variable with only the aerial parts killed, though often suppression will occur. The recovery of weeds will be reduced if the sward is growing vigorously at the time of treatment.
Annual Weeds
Annual weeds will be best controlled if spraying is done while the majority of weeds are seedlings.

CROP SPECIFIC INFORMATION
CEREALS
FARMCO UNDERSOWN may be used on all commercial varieties of Winter and Spring sown Wheat, Barley and Oats, Rye and Triticale.
FARMCO UNDERSOWN may also be used on cereals undersown with Grass or Lucerne
Water Volume: Apply in 200 to 400 L/ha.
Use a minimum rate of 225 L/ha in dense stands of cereals, or if weed growth is dense.
Spray quality: Apply as a medium quality spray (as defined by BCPC). A spray pressure of 2-3 bar is recommended.
Timing of application: FARMCO UNDERSOWN should be applied when the crop is actively growing and is at the correct growth stage.
The best results will be obtained if spraying is done while the majority of weeds are seedlings.
Winter Wheat, Barley and Oats, Triticale and Rye:
Apply FARMCO UNDERSOWN at a rate of 4.5 L/ha
Apply in the spring from the leaf sheath erect stage until before the first node is detectable (BBCH growth stage 10-31)
Do not apply in autumn, winter, during frosty weather or if frosts are expected following application.
Spring Wheat
Apply FARMCO UNDERSOWN at a rate of 4.5 L/ha
Apply from the
five leaf stage until before the first node is detectable (BBCH growth stage 15-31).
Spring Barley
Apply FARMCO UNDERSOWN at a rate of 4.5 L/ha
Apply from the three leaf stage until before the first node is detectable (BBCH growth stage 13-31).
Spring Oats
Apply FARMCO UNDERSOWN at a rate of 4.5 L/ha
Apply from the three leaf stage until before the first node is detectable (BBCH growth stage 13-31).
Undersown Cereals
Apply FARMCO UNDERSOWN to undersown cereals at a rate of 4.5 L/ha.
Application should be made when the cereal crop is at the correct growth stage, as listed above AND when the undersown crop of lucerne or grass is at the correct growth stage as listed in the grassland section below.

GRASSLAND AND LUCERNE
FARMCO UNDERSOWN may be used on Establi
shed Grassland (permanent pasture) and Newly Sown Grass.
FARMCO UNDERSOWN may also be used on Lucerne (alfalfa) and swards containing a mixture of Grasses and Lucerne.
Water volume: Apply in 200 to 1000 L/ha.
Use a minimum of rate 225 L/ha in dense swards, or if weed growth is dense.
Spray quality: Apply as a medium quality spray (as defined by BCPC). A spray pressure of 2-3 bar is recommended.

Established Grassland
FARMCO UNDERSOWN should be applied to established grassland at a rate of 4.5 L/ha.
A top dressing ten days before treatment is recommended to assist kill of weeds and subsequent recovery of the sward.
The time of application is best determined according to the growth stage of weeds present (See Weed Control section).
Newly Sown Grass
FARMCO UNDERSOWN should be applied to young grass leys at a rate of 4.5 L/ha.
Spray when the grasses have at least four leaves and have begun to tiller. Where several species of grass are present the timing should be dictated by the slowest developing species. Applications before tillering may cause a temporary
check to growth.
Lucerne (Alfalfa)
FARMCO UNDERSOWN should be applied to lucerne at a rate of 4.5 L/ha.
Spray from the first trifoliate leaf until the fourth trifoliate leaf stage.

MIXING
Apply using a conventional ground vehicle mounted/drawn equipment. Ensure that all application equipment is clean. Add half the required volume and start agitation, add the required quantity of FARMCO UNDERSOWN. Fill the tank to the
required volume whilst maintaining agitation. Triple rinse containers with water and add washing to the spray tank.
Continuous agitation must be maintained until spraying is complete. After use, the spraying machine must be thoroughly cleaned.
Wash Equipment thoroughly with water and wetting agent or liquid detergent immediately after use.
Spray out, fill with clean water and leave overnight. Spray out again before storing or using for another product. Traces of FARMCO UNDERSOWN can cause harm to susceptible crops sprayed later.
