Barclay Gallup Biograde 450
Contains 450 g/l glyphosate in a soluble concentrate.
A systemic herbicide for the control of annual and perennial grass and broadleaved weeds in stubbles, grasslands, orchards, forestry, set-aside, non-crop areas, and for pre-harvest use in cereals, oilseed rape, linseed and peas (combining) and field beans.
Barclay Gallup Biograde 450 is a foliar acting herbicide that controls annual and perennial grasses and most broad-leaved weeds when used as directed. It is translocated from treated vegetative growth to underground roots, rhizomes or stolons. Leaf symptoms, being a reddening then yellowing of the foliage, are first seen on grass weeds but take longer to appear on broad-leaved weeds.
It is particularly important that the weeds have sufficient leaf growth and are actively growing when treated.
Perennial grass weeds must have produced fresh leaves, which are green and vigorous. Common couch or scutch is most susceptible to Barclay Gallup Biograde 450 when it is tillering and when new rhizomes have begun to grow. This is usually when the plants have about 5-6 leaves, each with approximately 12-15 cm (5-6") of new growth.
The majority of perennial broad-leaved weeds are most susceptible if treated when they are actively growing and are at or near flowering stage.
Annual weeds should be actively growing with grasses having at least 5 cm (2") of leaf and broad-leaved weeds at least two expanded true leaves when sprayed.
Couch or scutch grasses and other grass and broad-leaved weeds are less susceptible to Barclay Gallup Biograde 450 when growth is restricted by drought, waterlogging, frost, very high temperatures or natural dieback. Efficacy will be reduced if such conditions occur at or immediately after spraying.
Occasionally a slight check to crop growth may occur, particularly after direct drilling when crop seeds germinate amongst a mass of decaying foliage, stolons, rhizomes or roots. Thorough cultivations are necessary to disperse or bury decaying organic matter. Consolidate loose soils and ensure crops are adequately fertilised and appropriate measures are taken to prevent insect and fungal damage to the following crop.
Do not apply lime, fertiliser, farmyard manure, pesticides or similar materials within 7 days of Barclay Gallup Biograde 450.
Note: Barclay Gallup Biograde 450 does not give acceptable control of horsetail, Equisetum arvense.
A period of at least 6 hours and preferably 24 hours free of rain must follow spraying. Do not spray onto weeds suffering from drought stress as reduced control may occur. Do not spray in windy conditions as drift onto other crops or vegetation can cause severe injury or destruction. Do not spray during frosty weather that prevents active growth and can induce weed senescence.
Tractor mounted sprayers
Pour the recommended quantity of Barclay Gallup Biograde 450 into the spray tank already half-filled with clean water and under agitation.
Top up the spray tank with more clean water to the required level, whilst maintaining agitation Spray out on the day of mixing.
Add the recommended quantity of Barclay Gallup Biograde 450 to the knapsack spray tank approximately one-third filled with clean water.
Agitate thoroughly with a clean rod or by shaking after replacing the lid until thoroughly mixed. Top up the tank with more clean water to the required level and agitate thoroughly before use. Spray out on the day of mixing.

APPLICATION & SPRAY QUALITY
Conventional hydraulic sprayers
Prepared spray solution should be applied as a MEDIUM of COURSE quality spray (BCPC definition) at nozzle pressures not exceeding 2.5 bar (35 psi).
Barclay Gallup Biograde 450 is a systemic weedkiller and is active at low doses.
Always take care to avoid spray drift. DO NOT SPRAY in windy weather or near to desirable species or amenity plants.
Barclay Gallup Biograde 450 may be used to control weeds on all mineral or organic soils or surfaces, including ash and gravel. Only weeds showing green leaf at the time of application can be killed. There is no residual activity with Barclay Gallup Biograde 450.
Barclay Gallup Biograde 450 is compatible with adjuvant 91690. DO NOT mix with any herbicide, insecticide or fungicide.
Barclay Gallup Biograde 450 has no long-lasting herbicidal activity in soils after application. Agricultural and horticultural quality soils may be planted up with trees after not less than 7 days after application, unless directed otherwise. Other amenity plants may be planted after the treated vegetation has died back or after cultivation. Under normal weather conditions, cultivations may be conducted 7 days after treatment. Under poor growing conditions wait for the characteristic red/yellow leaf symptoms to appear before cultivating.
CARE OF EQUIPMENT
Wash equipment thoroughly after use with water and cleaning agent to remove traces of herbicide. Traces of herbicide left in the equipment may damage crops sprayed later.
