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.

General Information
Glyfos Dakar is an effective herbicide when used as directed against most annual and perennial grasses and broad-leaved weeds.
Glyfos Dakar is translocated from the treated leaves throughout the plant and to underground roots, rhizomes and stolons. Symptoms such as gradual wilting and yellowing of foliage are rapidly visible in grass weeds but are slower to appear in broadleaved weeds.
Cultivation and drilling can take place 6 hours after application to control annual broad-leaved weeds, 24 hours after spraying annual grasses and 5 days after spraying perennial weeds. If direct drilling is practised 6 hours after application only small annual weeds should be present. Allow minimum 7 days if weather conditions are not favourable and before planting of trees, ornamentals, vegetables etc.

Weather Conditions
For best results a rain-free period of 6 hours (and preferably 24 hours) is required after application of Glyfos Dakar. Extreme care should be taken to avoid spray drift as this can severely damage or destroy neighbouring crops or plants. Action of Glyfos Dakar will be slower in cooler weather. It should not be used under frosty conditions while weed growth is reduced by natural senescence. Treating weeds which are suffering from drought stress may result in reduced efficacy.

Following Crops:
Glyfos Dakar is inactivated on contact with soil by binding to soil particles. All crops may be planted or sown at the intervals specified in ‘Conditions of Use’ following treatment. A slight growth retardation following germination may be seen if seeds are sown by direct drilling amongst decaying vegetation, roots, rhizomes or stolons.

DO NOT STORE, MIX OR APPLY THIS PRODUCT FROM AN UNLINED OR GALVANISED STEEL TANK. DO NOT leave mixtures in spray tanks over long periods. Ensure that spray tanks are always THOROUGHLY ventilated.
Apply this product carefully. Ensure spraying takes place only when weeds are actively growing (normally March to October) and is confined only to visible weeds including those in the 30cm swath covering the kerb edge and road gulley – do not overspray drains

Associated farming practices
Lime, fertilisers or other pesticides should not be applied for at least 5 days after the application of Glyfos® Dakar.

Weed control:
It is important when treating perennial weeds that there is full emergence of healthy green foliage and active growth at the time of application.
The efficacy of this product is increased if the leaf surface for absorption is large. Common couch grass is particularly susceptible at the 4-5 leaf stage, where there is about 10-15 cm of new growth, when tillering and new rhizome growth is starting. Most perennial broad-leaved weeds are particularly susceptible to treatment when they are actively growing and shortly before flowering. Annual weeds should be growing actively at the time of treatment. Grasses should have at least 5 cm of growth. Broad-leaved weeds should have at least two sizeable true leaves. Under conditions of drought, flooding, frost or high temperatures, disease or insect damage or weeds heavily covered with dust, where plant growth is restricted the efficacy of this product will be reduced.
Strains of some annual weeds (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. 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, CPA, your distributor, crop adviser or product manufacturer.
Do not use glyphosate repeatedly over several years in the same field as selection of resistant biotypes can take place and may become prevalent.
No extra surfactant should be added if the product is to be applied using a rotary atomizer sprayer.

Glyfos Dakar may be applied to all areas which will be planted with food and feed crops, preharvest to wheat and oats intended for milling and barley intended for brewing. Consult grain merchant or processor before using on contract grown crops or those intended for processing. Never apply pre-harvest treatment to crops grown for seed

Spray application techniques and equipment:
Glyfos Dakar is a water-soluble granular formulation with free-flowing, dust-free granules that dissolve rapidly in water. Application techniques include tractor-mounted sprayers, knapsack sprayers, rotary atomisers and specialised spraying equipment such as weed wiper applicators, where indicated.

Hydraulic sprayers mounted on tractors
Use any equipment which can apply at 80-250 litres/ha as a ‘Medium’ or ‘Coarse’ spray (as defined by BCPC) with a pressure of 1.5-2.5 bar and 80° or 110° nozzles. Pre-harvest applications should be made using high clearance tractors with narrow wheels and crop dividers, where the spray boom can be raised to just above the top of the crop. For most applications, 200-250 litres of water/ha should be used. Spray pressure (typically 1.5-2.5 bar) should be adjusted and related to tractor speed, water volume and nozzle type. However, specific low-volume nozzles may be used with a reduced water volume of 80-120 litres. When using low volume nozzles, spray pressure and tractor speed should be adjusted. A typical speed range would be 4-9 km/hour. When applying pre-harvest to crops, a low speed to avoid boom bounce is recommended.
All spray equipment should be calibrated before use, particularly if nozzles have been changed. Check at least one nozzle from each side of the boom. Before starting spraying, check that the boom is level, the boom height is correct for the intended application, and all the nozzles on the boom are aligned at the correct angle to the forward direction of the tractor.

Rotary Atomisers
Select one of the following:
CDA Boom and CDA Lightweight, Microdrop, Girojet, Dual-Option sprayer, Hydraspin. Applications should be made using a water volume of 40 l/ha at a speed of 4-9 km/hour and a droplet setting of 200-300 microns (equivalent to the BCPC definitions of ‘Medium’ or ‘Coarse’). The spray droplet spectrum produced by the atomiser must have a minimum Volume Median Diameter (VMD) of 200 microns. The equipment should be correctly calibrated according to the manufacturer’s instructions.

Directed Application with a Knapsack Sprayer
Knapsack sprayers (e.g. Cooper Pegler Classic / Series 2000) may be used in set-aside land and precultivation. Spray volumes normally range from 200-300 litres/ha but may be reduced to 100-150 litres/ha if low volume nozzles have been fitted. This is with the exception of application in forestry at 5 kg/ha where the minimum water volume is 200/ha. Spray quality should be ‘Medium’ or ‘Coarse’ as defined by BCPC.
An application rate of 2 kg/ha and a water volume of 200 litres/ha represents a 1% concentration of Glyfos Dakar. A knapsack sprayer with a total capacity of 10 litres thus requires 100 g of Glyfos Dakar in 10 litres of water.
A 10-litre sprayer will cover an area of 500 sq. metres at a 1 metre/second walking pace and a 1-metre wide spray swath.

Spray Application in or near waterways
Before using Glyfos Dakar for control of aquatic weeds in or near waterways read the official recommendations entitled “Guidelines for the use of Herbicides on weeds in or near Watercourses and Lakes”. This document may be obtained from Scottish Executive Environment and Rural Affairs Department (SEERAD), The Department of Agriculture Northern Ireland and the National Assembly for Wales Agricultural Department (NAWAD). Consult the appropriate regulatory body (Environment Agency/Scottish Environment Protection Agency) before applying Glyfos Dakar for control of weeds in or near waterways.
The maximum concentration of active ingredient treated water must not exceed 0.06 ppm or such lower concentration as the appropriate regulatory body may require.
When using Glyfos Dakar following label recommendations, water subjected to spray drift may immediately be used for irrigation.
Filling spray tank
1) Fill the sprayer with 2/3 of the required quantity of water.
2) Switch-on the agitation and re-circulation.
3) Add the granules progressively and when completed add the remaining water. Continue agitation for at least 5 minutes. Induction hopper When using a chemical induction bowl or hopper, open the rinsing/flush system. Next open the valve for emptying the bowl into the main tank. Add Glyfos® Dakar with the rinsing/flushing system on. Continue until the required amount of Glyfos Dakar has been introduced.
