A herbicide for control of a range of grass and broad-leaved weeds in grain and forage maize. The (COSHH) Control of Substances Hazardous to Health Regulations may apply to the use of this product at work.

DIRECTIONS FOR USE
Important:This information is approved as part of the product label. All instructions within this section should be read carefully in order to obtain safe and successful use of this product.

General Information:
Entail is a highly active sulfonyl-urea herbicide with foliar and root activity for post-emergence use against a range of broad-leaved and grass weeds in forage and grain maize. It is most effective when applied to actively growing weeds. Good spray cover of the weeds must be obtained. Weed control may be reduced when soil conditions are very dry, however with adequate soil moisture, susceptible weeds germinating soon after treatment will be controlled.

Cautions
Do not apply Entail to a crop to which an organophosphate soil insecticide has been applied.
Under certain conditions, some transient yellowing, crop stunting and/or loss of vigour may be observed within 1 -2 weeks after treatment. These will soon be outgrown and will not adversely affect yield.
Do not apply this product to any crop suffering from stress as this may lead to more persistent crop damage. Avoid overlapping spray swaths which may cause substantial crop damage leading to loss of yield.
Strains of some annual grass weeds (e.g. black-grass, wild-oat, Italian rye-grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing 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 adviser or product manufacturer.
Avoid using Entail (or any other ALS-inhibiting herbicide) as the sole means of weed control in successive crops. Do not use the product to control light infestations of weeds.
Extreme care must be taken to avoid spray drift onto non-crop plants outside of the target area. Thorough cleaning of equipment is also very important - see SPRAY TANK CLEAN-OUT.
This product may cause flower deformation on particularly sensitive varieties.
Do not apply this product to any maize crop in sequence or in tank-mixture with any product containing an ‘ALS inhibiting’ herbicide. 

Soil Types and Weather Conditions: Entail can be applied to all soil types. Very dry soil conditions may reduce weed control.
Weed Control: The susceptibility ratings of weeds in the weed control table assume good spray cover and growing conditions. An esterified rapeseed oil adjuvant should be used with the herbicide, at a concentration of 0.5% of total spray volume. Headland Fortune (ADJ 0703) is recommended.

Susceptible weeds: Generally 80-100 % control may be expected in good conditions.
Moderately susceptible weeds: Generally 70-90% control may be expected in good conditions.
Moderately resistant weeds: Generally 60-80% control may be expected in good conditions.

Weed Resistance: 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 dominant. A weed species is considered resistant to a herbicide if it survives correctly applied treatment at the recommended dose.
Development of resistance within a weed species can be avoided or delayed by sequencing or tank-mixing with suitable products having a different mode of action. This is particularly important if continuous maize if grown.
Entail is a sufonylurea herbicide. Its mode of action is via ALS inhibition. Use only as part of a resistance strategy that includes cultural methods of control and does not use Entail or any other ALS inhibitor as the sole chemical method of grass weed control. A strategy for preventing and managing resistance should be adopted. The Weed Resistance Action Groups have produced guidelines and copies are available from HGCA, CPA, your distributor, crop adviser or product manufacturer.
This product contains nicosulfuron which is an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B‘.

Application Rates and Timings: Apply 170 ml/ha at the 2 to 8 leaf stage of the crop (2 leaf to early tillering stage of grass weeds; 2 to 6 leaf stage of broad-leaved weeds). Select the rate according to the target species as listed in the weed control table above. An esterified rapeseed oil adjuvant should be used with the herbicide, at a concentration of 0.5% of total spray volume. Headland Fortune (ADJ 0703) is recommended.

Water Volume: Apply in 200 – 400 litres of water per hectare, using suitable equipment to give good spray cover of the weeds. When applying Entail extreme care should be taken not to overlap spray swaths. Entail should be applied as a MEDIUM spray (as defined by BCPC).

Mixing and Application: Half-fill the spray tank with clean water and begin agitation. Add the required quantity of Entail to the water. Rinse the empty container thoroughly with water three times and add the rinsings to the tank. Complete the filling and add the adjuvant oil to the spray tank as the last operation. Apply without delay. Maintain agitation while travelling and throughout the spraying operation.
Wash out the sprayer thoroughly after use using a recognised tank cleaner following the ‘Spray Tank Clean-out’ guidance below.

Following Crops: In normal rotation, after ploughing, winter wheat, winter barley, winter rye and triticale may be sown. All other crops may be sown the following spring. In the event of crop failure, maize can be sown after ploughing.

Spray Tank Clean-out: To avoid subsequent damage to sensitive crops thoroughly remove all traces of Entail from spraying equipment immediately after spraying, using the following procedure:
1. Immediately after spraying, drain the tank completely. Wash any contamination off the outside of the sprayer with clean water.
2. Rinse the inside of tank with clean water and flush at least one tenth of the spray tank volume through the boom and hoses. Drain the tank completely.
3. Half-fill the tank with clean water and add the correct quantity of ALL CLEAR™ EXTRA. Agitate and then flush the boom and hoses with the solution. Top up completely with water and allow to stand for 15 minutes with agitation.
4. Again flush the boom and hoses and drain tank completely (if it is not possible to drain tank completely, repeat step 3 before going on).
5. Remove all the nozzles and filters and soak them in a bucket containing 50ml ALL CLEAR EXTRA per 10 litres water.
6. Rinse tank again with clean water and flush at least one tenth of the tank volume through the boom and hoses. Drain the tank completely.
7. For disposal of washings, follow the Code of Practice for the Safe Use of Pesticides on Farms and Holdings. Do not spray onto sensitive crops or land intended for planting with sensitive crops
