DU PONT - herbicide

A water-dispersible granule containing 750 g/kg nicosulfuron for weed control in forage maize.

Directions for use

Weed control
ACCENT contains nicosulfuron, a sulfonylurea (ALS inhibitor) herbicide which works mainly by contact action and is most effective if applied when the weeds are small and actively growing.
Good spray cover of the weeds must be obtained for best results. Susceptible plants cease growth almost immediately after application and symptoms can be seen about two weeks after application.
Weed control may be reduced when soil conditions are very dry. The susceptibility rating of weeds in the following tables are from the cotyledon to 4 leaf stage with good spray cover and growing conditions.

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 cons idered resistant to a herbicide if it survives a correctly applied treatment at the recommended dose. Development of resistance with a weed species can be avoided or delayed by alternating (or tank mixing) with suitable products having a different mode of action. ACCENT should be used in mixture and/or sequence with other mode of action herbicides, particularly in continuous maize, as part of a weed resistance management plan.
Strains of some annual grasses (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 TEAGASC,HGCA, CPA, your distributor, crop advisor or product manufacturer.
This product contains nicosulfur on, which is an ALS inhibitor, also classified by the Herbicide Resistance Action Committee as ‘Group B’. Use only as part of a resistance management strategy that includes cultural methods of control and does not use ALS inhibitors as the sole chemical method of grass-weed control.

ACCENT can be used on all varieties of forage maize between the growth stages given below.
Transient yellowing and/or crop stunting can be seen from 1 to 2 weeks after treatment. This is quickly outgrown with no impact on yield. In the case of particularly sensitive varieties (consult supplier), some crop damage may be caused from which recovery may not be complete.

Apply ACCENT at 60 g/ha. An adjuvant (UK only: e.g. Pro-Mix or Prompt) should be added as a rate of 100 ml per 100 litres of water.

ACCENT may be applied from the 2 leaf stage (BBCH 12) up to and including the 8 leaf stage of crop growth (BBCH18).

Following crops
Winter wheat and winter barley may be sown, after ploughing, in normal crop rotation. All other crops may be sown in the following spring. In the case of crop failure, maize may be re-sown after ploughing.

Volume and application
Application should be made in 200-300 litres of water per hectare, using suitable ground equipment to give good spray cover of the weeds. The higher volume is recommended when crops are thick or weed growth is dense. Care should be taken not to overlap spray swaths.

Quarter fill the spray tank with clean water, start the agitation and add the required quantity of ACCENT directly to the tank without prior creaming. Continue agitation while topping up the tank and while spraying.
