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.
DO NOT apply before undersowing.
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.

CROP SPECIFIC INFORMATION
Always spray when the crop is actively growing.
Grassland
Application rate: 2.7 product/ha
Maximum total dose: 5.4 L product/ha
Use on established grassland and leys no less than 1 year old. Apply POL-MCPA 500 SL in spring and summer when growing conditions are favorable. Spray grass for hay or silage 3–4 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 4–6 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.
Apply in 200 – 400 L water/ha

Grassland (seed crops)
Application rate: 2.7 L product/ha
Maximum total dose: 2.7 L product/ha
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 POL-MCPA 500 SL.
Apply in 200 – 400 L water/ha

MIXING AND SPRAYING
Half-fill the tank with clean water and add the required quantity of POL-MCPA 500 SL, and add the remainder of the clean water with gently agitation which should continue until the contents ate thoroughly mixed. Spray using a MEDIUM/COARSE spray (BCPC).

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
POL-MCPA 500 SL can be tank-mixed with other pesticides, please consult your distributor.

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. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.
