A post emergence translocated herbicide for the control of bracken. A soluble concentrate containing 400 g/L (33.6% w/w) of the sodium salt of asulam.

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
Fronds must not be damaged by stock, frost (bronzed and stunted fronds) or by cutting before treatment. DO NOT apply during or immediately after drought periods or in conditions of high temperature and low humidity.
DO NOT cut bracken for at least 4 weeks after spraying to permit movement of ASULOX to rhizome buds; preferably leave undisturbed until late autumn. Where Ragwort is present users should consult the Code of Practice on How to Prevent the Spread of Ragwort. Ragwort plants sprayed with this herbicide are more palatable and contain higher levels of toxins. Animals should be excluded from treated areas until any ragworth has completely recovered or died and there is no visible sign of the dead weed. Do not include treated ragwort in hay or silage crops. At least 6 weeks should elapse between applying ASULOX and sowing or planting any subsequent crop. DO NOT use adjuvants with ASULOX in forestry situations when overspraying trees.

WEEDS CONTROLLED
NOTE: No outward signs of the effects of ASULOX on bracken will be observed during the current season following application. The effects only become apparent the following spring when normal frond emergence in treated bracken fails to occur. Apply ASULOX on a dry day. Ideally, there should be 24 hours without rain to allow for adequate uptake of ASULOX into the bracken plant. Light rain after 6 hours should not adversely affect activity.

Primary clearance treatments and containment
Bracken should be treated in full frond (all fronds fully expanded) but before yellowing (start of senescence). Normally this will be within the period mid July to late August.

Follow up treatments for bracken clearance
Because of dormant buds on the rhizome system of bracken, complete control will not be achieved by a single application of ASULOX. If bracken is to be cleared, annual re-treatment of re-growth using spot applications is essential. Re-growth tends to be stunted but should be treated at the same timing as primary applications, irrespective of the state of frond development. IF NO FOLLOW UP TREATMENT OR LAND IMPROVEMENT PROGRAMME IS CARRIED OUT, THE LAND IS LIKELY TO BE RE-INFESTED WITH BRACKEN WITHIN 5 YEARS OF A PRIMARY APPLICATION.

MIXING
For IBC containers use mechanical handling. Depending on application method (see below), ASULOX can be applied in a water based system with or without a suitable adjuvant (See the Chemicals Regulation Directorate Official List for details). Adjuvants enhance the uptake of ASULOX by the bracken fronds thereby improving reliability under adverse conditions. Adjuvants should NOT be used in forestry situations when overspraying trees or other situations where selectivity of the applied spray may be critical.
Half fill the spray tank or container with water and then pour in the required amount of ASULOX. Top up with water then add an adjuvant where this is required. Ensure thorough mixing before commencing spraying.

CROP SPECIFIC INFORMATION  
Only one application should be made per crop/ situation per year 
As a general rule, no bracken spraying should be attempted along stream banks, wet gulleys, screes and other locations where rare or unusual plants are often to be found

Grassland species tolerance to ASULOX
Some grasses and herbs may be damaged by ASULOX. In practice, a dense bracken canopy protects the underlying vegetation and any check to these species is usually only temporary. The more sensitive species include Yorkshire fog, Timothy, Cock’s foot, bents, annual meadow grass, daisy, docks, plantains, saxifrage and all other ferns.

RESISTANCE
Total reliance on one pesticide will hasten the development of resistance. Pesticides of different chemical types or alternative control measures should be included in the planned programme. Alternating with different modes of action is a recognised anti resistance strategy
