Additional Safety Phrases
To protect aquatic organisms respect an unsprayed buffer zone of five metres to surface water bodies.
Direct spray away from water.
Extreme care must be taken to avoid spray drift onto non-crop plants outside the target area.
Livestock must be kept out of treated areas until poisonous weeds such as ragwort have died and become unpalatable.
Do not contaminate water with the product or its container. (Do not clean application equipment near surface water. Avoid contamination via drains from farmyards and roads.)
DO NOT apply if rain is forecast within 48 hours.
DO NOT apply to saturated soils.

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 or harrow within a week of spraying.
DO NOT mow within four days of application.
DO NOT treat newly established grass less than one year old.
DO NOT treat grass suffering from drought, disease, during freezing conditions when rain is imminent or other adverse factors.
Extreme care must be taken to avoid spray drift onto non-crop plants outside of the target area.
DO NOT spray in windy weather, avoid drift on to neighbouring crops, especially beans, beet, brassicas, carrots, legumes, lettuce and tomatoes which are very susceptible.
WASH EQUIPMENT thoroughly immediately after use. Rinse with water three times, drain and allow to dry. Traces of herbicide left in the sprayer may damage susceptible crops if these are subsequently sprayed using the same equipment.
Do not apply in volumes less than 200 litres of water per hectare.

WEEDS CONTROLLED
Established grassland and grass seed crop

Susceptible (Consistently good control of both roots and shoots):
Greater Plantain, Ribwort Plantain

Moderately susceptible (Weeds suppressed and top-growth usually killed):
Meadow Buttercup (Treat in spring or early summer), Cat’s Ear, Hoary Cress, Common Daisy, Autumn Hawkbit, Common Knapweed, Common Ragwort (Spray in spring when in rosette stage before flower spike starts to grow), Compact Rush (Spray in April to June. Cut and remove stems either four weeks before or after treatment), Soft Rush (Treat as Compact Rush), Self Heal, Creeping Thistle (Treat at early flower bud stage), Spear Thistle.

Moderately resistant (Top growth only may be killed):
Bulbious Buttercup (Treat in Autumn n new leaf or in spring), Creeping Buttercup (Treat in Spring or early summer), Colt’s foot, Dandelion, Meadowsweet, Hard Rush (Treat as Compact Rush). Common Sorrel, Sheep’s Sorrel, Dwarf Thistle, Yarrow.

CROP SPECIFIC INFORMATION
Always spray when the crop is actively growing.

Established grassland
Dose 2.7 l/ha.
Maximum total dose 5.4 l/ha.
Timing
Use on established grassland and leys not less than one year old. Apply NU46 in spring and summer when growing conditions are favorable. Spray grass for hay or silage three to four weeks before cutting. Clover may be checked but recovers by the following spring. Follow-up applications may also be needed where new seedling weeds appear.An interval of four to six weeks should elapse between successive applications if weeds persist.
A top dressing ten days before treatment is recommended to assist kill of weeds and subsequent recovery of the sward. Annual weed species 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 the weeds will be reduced if the grass is growing vigorously at the time of treatment.
Water volume
Apply in 200–400 litres water per hectare.

Grass seed crops
Dose 2.7 l/ha.
Maximum total dose 2.7 l/ha.
Timing
The safe period for treatment occurs when the grasses have at least four leaves and have begun to tiller but at least five weeks preceding ear emergence. The best time varies according to the species and strain of grass concerned. Do not apply more than 2.7 l/ha of NU46.
Water volume
Apply in 200–400 litres water per hectare

MIXING AND SPRAYING
Half-fill the tank with clean water and add the required quantity of NU46, and add the remainder of the clean water with gently agitation which should continue until the contents are thoroughly mixed. Triple rinse containers with water and add washing to the spray tank.

Tank cleaning
WASH EQUIPMENT thoroughly immediately after use. Rinse with water three times, drain and allow to dry. Traces of herbicide left in the sprayer may damage susceptible crops if these are subsequently sprayed using the same equipment.

COMPATIBILITY
NU46 can be tank-mixed with other pesticides, please consult your Nufarm distributor or Nufarm UK Limited.

RESISTANCE MANAGEMENT
When herbicides with the same mode of action are used repeatedly over several years in the same field, selection of resistant biotypes can take place. These can propagate and may become dominating. A weed species is considered to be resistant to a herbicide if it survives a correctly applied treatment at the recommended dose. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures.
