An oil dispersion formulation containing 60 g/kg nicosulfuron and 4 g/l thifensulfuron-methyl for broad-leaved weed and grass weed control in maize.

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
COLLAGE should not be applied to any crop suffering from stress as a result of drought, waterlogging, low temperatures, pest or disease attack, nutrient or lime deficiency or other factors reducing crop growth.
Do not use COLLAGE on crops undersown with grasses, clover or other legumes or any other broad-leaved crop.
Due to the high level of activity of the herbicide, special care must be taken to avoid damage by drift onto broad-leaved plants outside the target area, or onto ponds, waterways or ditches. Thorough cleansing of equipment is also very important - see below.
Contract agents should be consulted before using on crops grown for seed.
Do not apply COLLAGE more than once to any maize crop.
Do not apply COLLAGE to forage maize treated with organo - phosphate (OP) insecticides.
All requirements or restrictions on other product labels must be adhered to when applied to the same crop as COLLAGE. Contact your DuPont distributor for further information.

Weed control
COLLAGE contains nicosulfuron and thifensulfuron methyl, sulfonylurea (ALS inhibitor) herbicides which work 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 following weeds are susceptible from the cotyledon to 4 leaf stage:
Annual meadow grass (Poa annua)
Couch (Elytrigia repens) – top growth only
Green foxtail (Setaria spp.)
Redshank (Polygonum persicaria)
Red deadnettle (Lamium purpureum)
Mayweed spp.
Fat hen
Common Chickweed

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 dominating. A weed species is considered 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. COLLAGE 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 Committee and copies are available from your distributor, crop advisor or product manufacturer. This product contains nicosulfuron and thifensulfuron methyl, which are ALS inhibitors, 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.

Crops
COLLAGE can be used on all varieties of maize between the growth stages given below. Under certain climatic, soil and crop conditions some slight chlorosis and stunting of the crop may occur. Affected crops will quickly recover with no effect on yield.

Dose
Apply COLLAGE at 0.75 l/ha.

Timing
COLLAGE 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
BEFORE USING ACCENT, SPRAYING EQUIPMENT MUST BE CLEAN AND FREE FROM CONTAMINATION WITH OTHER PESTICIDES. Application should be made in 200-400 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.

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

Compatibility
In any tank-mix add COLLAGE to the tank first and ensure it is fully dispersed before adding the partner product. Do not allow COLLAGE to come into contact with undiluted pesticide concentrate. Products should only be tank-mixed if each product can be applied within the label recommendations for its use. For further information contact your DuPont distributor.
