For the control of most annual and perennial grasses and broad-leaved weeds.
A soluble concentrate containing 450 g/1 glyphosate present as 607 g/1 (50.9% w/w) of the isopropylamine salt.
Glyfos Supreme is an effective herbicide when used as directed against most annual and perennial grasses and broad-leaved weeds.
Glyfos Supreme 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 broad-leaved 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.
For best results a rain-free period of 6 hours (and preferably 24 hours) is required after application of Glyfos Supreme.
Extreme care should be taken to avoid spray drift as this can severely damage or destroy neighbouring crops or plants.
Action of Glyfos Supreme 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.
Associated farming practices
Lime, fertilisers or other pesticides should not be applied for at least 5 days before or after the application of Glyfos Supreme
Glyfos Supreme 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.
Mixing and Application
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.
NEVER APPLY PRE-HARVEST TREATMENTS TO CROPS GROWN FOR SEED. Barley intended for brewing and contract-grown crops should only be treated following approval from the grain merchant. Consult processor before using on crops intended for processing.
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 5cm 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.
No extra surfactant should be added if the product is to be applied using a rotary atomiser.
GLYFOS SUPREME may be applied to all areas to be planted with food and feed crops and pre-harvest to wheat and oats and barley intended for brewing. Consult the processor before using on any crop intended for processing. Only treat barley intended for brewing and contract crops after having obtained approval from the grain merchant.
Some strains of 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. 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 or the Crop Protection Association.
Do not use Glyphosate products repeatedly over several years in the same field as selection of resistant biotypes can take place and may become prevalent.
SPRAY APPLICATION TECHNIQUES AND EQUIPMENT
I. 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 800 or 1100 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
2. 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 1/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.
3. Directed Application with a Knapsack Sprayer
Knapsack sprayers (e.g. Cooper Pegler Classic / Series 2000) may be used in forestry, orchards, set-aside land, land not intended to bear vegetation and pre-cultivation. 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 (do not use less than 200 litres/ha when applying to control rhododendrons). Spray quality should be 'Medium' or 'Coarse' as defined by BCPC. When using a knapsack sprayer with a total capacity of 10 litres applying 3.2 litres/ha with a spray volume of 200 litres/ha gives a concentration of 1.6%, thus requiring 0.16 litres of Glyfos Supreme in 9.84 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.
Weedwiper Applications (e.g. Weedwiper Mini)
Weedwipers may be used in orchards and non-crop areas. Apply a solution of 0,7 parts Glyfos Supreme with 2 parts water for Weedwiper Minis, or 0.7 parts Glyfos Supreme to 1 part water for other wipers.
Spot Gun-Tree injection
The applicator must be fitted with a solid stream nozzle, either a Spraying Systems 0006 or a Delavan LF 6.0. Set the gun to apply L6 ml of neat GLYFOS SUPREME per cut.
Spot Gun – Stump treatments
The applicator must be fitted with narrow angle cone nozzles (TG3 or TG5) or solid stream nozzle tips (Delavan LF 6.0 or Spraying Systems 0006). Set the gun to deliver 4 ml per squeeze and select the concentration of GLYFOS SUPREME according to usage recommendations. A dose of 4 ml should be applied for each 5 cm diameter of tree stump
FILLING SPRAY TANK
Half fill clean spray tank with clean water, add required quantity of product and mix well: add remaining water. Do NOT use mechanical agitators. Place the filling hose below water level to prevent excessive foaming and remove immediately after filling to prevent back- siphoning. When tank-mixing with other products recommended on the label add the other product before adding GLYFOS SUPREME, then add the remaining water
It is essential to thoroughly clean out spray tanks, pumps, pipelines and nozzle or disc assemblies with a recommended detergent cleaner between applying this product and other pesticides, to avoid contamination by pesticide residues.
