Active materials

FRONTSWEEP is a soluble concentrate containing 480 g/l (41.5% w/w) of the isopropylamine salt of glyphosate (equivalent to 360 g/l glyphosate) and ethoxylated tallow amine surfactant.

DIRECTIONS FOR USE
IMPORTANT: This information is approved as part of the Product Label. It is advisable to read all the instructions within this section carefully in order to obtain safe and successful use of this product.

Warnings
DO NOT MIX, STORE OR APPLY FRONTSWEEP IN GALVANISED OR UNLINED STEEL CONTAINERS OR SPRAY TANKS.
EXTREME CARE SHOULD BE TAKEN TO AVOID SPRAY DRIFT AS THIS CAN SEVERELY DAMAGE OR DESTROY NEIGHBOURING CROPS OR PLANTS
DO NOT leave spray mixtures in tank for long periods and make sure tanks are WELL VENTED.

Restrictions
A period of at least 6 hours and preferably 24 hours rain-free must follow application of FRONTSWEEP.
Do not spray in windy conditions as drift onto desired crops or vegetation could severely damage or destroy them.
Do not spray onto weeds which are naturally senescent, or where growth is impaired by drought, high temperatures, a covering of dust, fl ooding or frost at, or immediately after application, otherwise poor control may result.
Applications of lime, fertilizer, farmyard manure and pesticides should be delayed until 5 days after application of FRONTSWEEP.
After application, large concentrations of decaying foliage, stolons, roots or rhizomes should be dispersed or buried by thorough cultivation before crop drilling.

Other specifi c restrictions:
When applying through rotary atomizers the spray droplet spectra produced must be of a minimum Volume Median Diameter (VMD) of 200 microns.
Weed wipers may be used in any recommended crop where the wiper or chemical does not touch the growing crop. The maximum concentrations used must not exceed the following:
Weed wiper mini: 1:2 dilution with water
Other wipers: 1:1 dilution with water
The maximum individual dose for hydraulic knapsack sprayers must not exceed 22.5 g/l glyphosate
For stump application, the maximum concentration must not exceed 200 ml of product per litre of water (i.e. a 20% solution)

Weeds Controlled
FRONTSWEEP is a foliar acting herbicide which controls annual and perennial grasses and most broad-leaved weeds when used as directed. It is important that all weeds are at the appropriate stage when treated, otherwise some re-growth may occur which would need retreatment.
Apply FRONTSWEEP herbicide once grasses and broad-leaved weeds have emerged and they have ACTIVELY GROWING green leaves.
- PERENNIAL BROAD-LEAVED WEEDS are most susceptible at the fl owering stage.
- PERENNIAL GRASSES must have a full emergence of healthy, green leaf. For example, common couch becomes susceptible at the onset of tillering and when new rhizome growth commences, which usually occurs when plants have 4 -5 leaves with 10 – 15 cm of new growth.
ANNUAL GRASSES AND BROAD-LEAVED WEEDS should have at least 5 cm of leaf, or 2 expanded true leaves, respectively. In setaside, annual grasses are best treated at full ear emergence, or before stem elongation. Application during the stem extension phase of annual grasses e.g. Black-grass and Brome species on set-aside between the end of April and end of May, may result in poor control and require re-treatment.
BRACKEN should be treated after frond tips are unfurled, but pre-senescence.
OTHER SPECIES – recommendations for specifi c Areas of Use are given in the Recommendation Tables, below.
This product will not give an acceptable level of control of Horsetails (Equisetum arvense)

Following Crops
Upon soil adsorption the herbicidal properties of FRONTSWEEP are lost permitting the drilling of crops 48 hours after application.
Planting of trees, shrubs etc may take place 7 days after application. Grass seed may be sown from 5 days after treatment. Refer to the ‘Recommendation Tables’ for specifi c restrictions on direct drilled crops.

Weed Resistance Strategy
There is low risk for the development of weed resistance to FRONTSWEEP.
Strains of some annual weeds (e.g. Black-grass, Wild oats and Italian Ryegrass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. This should include integrating herbicides with a programme of cultural control measures. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, your distributor, crop adviser or product manufacturer, SOYL Ltd. Growers are encouraged to implement a weed resistance strategy based on (a) Good Agricultural Practices and (b) Good Plant Protection Practices by:
- Following label recommendations
- Monitoring performance and reporting any unexpected results to SOYL Ltd.
- Minimizing the risk of spreading weed infestations
- The implementation of good spraying practice to maintain effective weed control
- The adoption of complimentary weed control practices
- Using the correct nozzles to maximize coverage
- Application only under appropriate weather conditions

Mixing and Spraying
FRONTSWEEP mixes readily with water and can be applied in spray volumes ranging from 80-400 l/ha using tractor mounted, knapsack, rotary atomizers and hand-held sprayers. Specialized application equipment such as weed wipers, stem injection and spot gun applicators may be used where indicated.
Correctly calibrate all sprayers under fi eld or use conditions prior to application

Compatibility
Consult your distributor before tank mixing with any adjuvants or other pesticides.

General Information
FRONTSWEEP is taken up by foliage and translocated to underground roots, rhizomes and stolons, providing control of both annual and perennial grasses and broad-leaved weeds. FRONTSWEEP is rapidly adsorbed onto particulate matter in soils and water and is quickly degraded by the micro-organisms present in soil and aquatic bottom sediments. Until degraded, the active ingredient in FRONTSWEEP, glyphosate, is practically immobile in soils and is, therefore, unlikely to contaminate groundwater.

Symptoms on the Weeds
Symptoms of treatment are generally first seen 7-10 days after spraying, or longer (if growth is slow). These take the form of leaf reddening followed by yellowing and are usually quicker to appear on grasses than on broad-leaved weeds. Reaction of nettles is slow
