The results of the LERAP must be recorded in written form and must be available for a period of three years for inspection to any person entitled to exercise enforcement powers under or in connection with the Food and Environment Protection Act 1985 (as amended). (An electronic record will satisfy the requirement for a written record, providing it is similarly available for inspection and can be copied.)

Do not apply by hand-held equipment.

To avoid the build up of resistance do not apply this or any other product containing an ALS inhibitor herbicide with claims for control of grass-weeds more than once to any crop.

Extreme care must be taken to avoid spray drift onto non-crop plants outside of the target area.

 

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.

 

DO NOT treat CREW once a soil insecticide based on a organophosphate has been applied.

DO NOT apply CREW and a foliar treatment containing an organophospate insecticide to the same maize crop.

DO NOT mix with foliar or liquid fertilizers.

DO NOT spray in windy conditions as the spray drift may cause damage to neighbouring crops.

Applications should not be made to maize crops under stress as this may lead to incidences of more persistent crop damage, such as loss of vigour, particularly when poorer growing conditions follow treatment. This may cause loss of yield. Take care to ensure that the product is applied evenly at the recommended dose to a healthy crop.

Under certain conditions, some transient yellowing and/or crop stunting and/or loss of vigour can be seen from one to two weeks after treatment (two-eight leaves of maize). This is quickly outgrown and no yield effect has been shown.

Some flower deformation may be seen on particularly sensitive varieties e.g. Rival.

DO NOT apply this product to any maize crop in sequence or in tank-mixture with any product containing an ‘ALS inhibiting’ herbicide.

 

1.0 l/ha.

Apply from the two leaf stage of the crop up to and including eight leaf stage (GS 12–18).

Apply in 200 litres of water per hectare.

 

Plant only cereals or maize as following crops. Winter wheat can be drilled four months after application of 1.0 l/ha CREW, maize can be sown the following spring and all other crops from the following autumn onwards. Wheat should not be undersown.

 

CREW should be shaken before use.

Half fill the spray tank, and then start agitation. Add the required quantity of CREW to the tank. Maintain agitation during treatment. Spray using a MEDIUM Spray (BCPC).

 

 

 

ALTERNATIVELY USE THE FOLLOWING PROCEDURE:

1. Immediately after spraying, drain tank completely. Any contamination on the outside of the spraying equipment should be removed by washing with clean water.

2. Rinse inside of tank with clean water and flush through boom and hoses using at least onetenth of the spray tank volume. Drain tank completely.

3. Half fill tank with clean water and add 1/3 litre household ammonia (contains 9.5% ammonia) for each 100 litres of tank volume. (Equivalent amounts of alternate strength ammonia solutions can be used providing the final concentration in the full tank is 0.03%). Agitate and then flush the boom and hoses with the cleaning solution. Top up with water making sure the tank is completely full and allow to stand for 15 minutes with agitation. Again flush the boom and hoses and drain tank completely.

4. Nozzles and filters should be removed and cleaned separately with ammonia solution at the same concentration as used for the sprayer.

5. Rinse the tank with clean water and flush through the boom and hoses using at least onetenth of the spray tank volume. Drain tank completely.

6. For disposal of washings local regulations. Do not spray onto sensitive crop or land intended for cropping with sensitive crop.

NOTE: If it is not possible to drain the tank completely, step 3 must be repeated before going on to step 4.

 

This product contains nicosulfuron which is an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B’.

Use only as part of a resistance strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass-weed control.

Strains of some annual weeds (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.

Development of resistance within a weed species can be avoided or delayed by alternating (or tank mixing) with suitable products having a different mode of action.

Key aspects of the CREW weed resistance management strategy are:

Always follow the WRAG guidelines for preventing and managing herbicide resistance.

Avoid the use of CREW or any other ALS inhibitor herbicide as a sole means of grass and broadleaved weed control in successive crops.

Always monitor weed control effectiveness and investigate any occurrences of poor effectiveness. If unexplained contact your agronomist who may consider a resistance test appropriate.
