GENERAL INFORMATION

Clearall Supreme XL 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/scutch is most susceptible to
Clearall Supreme XL 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/scutch grasses and other grass and broad-leaved weeds are less susceptible to Clearall Supreme XL 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 Clearall Supreme XL.
Note: Clearall Supreme XL does not give acceptable control of horsetail, Equisetum arvense.
May cause long-term adverse effects in the aquatic environment

Clearall Supreme XL is a systemic weedkiller and is active at low doses. Always take extreme care to avoid spray drift. DO NOT SPRAY in windy weather or near to desirable species or amenity plants as drift onto other crops or vegetation can cause severe plant injury or destruction.
