DIRECTIONS FOR USE
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.

MODE OF ACTION
Clayton APT is a sulfonylurea herbicide, active against a range of broad-leaved weeds and grasses primarily by
root or shoot uptake. Control of susceptible weeds is commonly gained for a period of up to 5 months. Emerged
weeds are less susceptible to treatment and therefore, for post-emergence application, Clayton APT is
recommended to be co-applied with a herbicide such as glyphosate – see COMPATIBILITY. Post-emergence
applications give best results when weeds are young and actively growing under moist, warm weather conditions;
avoid application when weeds have started to senesce.
USE SITUATIONS
Clayton APT is recommended for the control of weeds on certain specified areas not intended to bear vegetation.
The specified areas are natural soil surfaces, permeable surfaces overlying soil and the ballasted surfaces of
railway tracks; apart from railway tracks, no other hard surfaces may be treated.
TIME OF APPLICATION AND WEATHER
Optimum results are obtained from an application of Clayton APT made in late winter of early spring before fresh
weeds germinate. If weeds have emerged it is recommended that Clayton APT is co-applied with a suitable
partner – see COMPATIBILITY. Post-emergence applications to weeds suffering stress owing to drought, frost,
high temperatures, water-logging, natural dieback or other environmental condition will not be growing actively
and so will not be well controlled.
RATE OF APPLICATION
Apply Clayton APT at 150 g/ha in all permissible situations.
APPLICATION
Apply through a conventional powered hydraulic sprayer or knapsack sprayer as a MEDIUM spray (BCPC) in
200-600 l/ha of water to give even coverage of the weeds and ground. Do not apply as a FINE spray liable to
drift. Spray accurately to avoid overlapping spray swaths. Avoid spray drift. Do not apply when a temperature
inversion is occurring. Do not spray under windy conditions.
MIXING
Ensure that the spray equipment is clean, in good mechanical order and correctly adjusted and calibrated before
use. Half-fill the spray tank with clean water and put under agitation. Add the required amount of Clayton APT to
the water. If co-applying with glyphosate (see COMPATIBLITY), add the required amount of glyphosate after the
Clayton APT has been thoroughly dispersed. Fill the tank with water to the required level and keep the mixture
under agitation until completion of spraying. Do not allow spray mixture to stand in the spray tank overnight.
COMPATIBILITY AND TREATMENTS IN SEQUENCE
Clayton APT is physically compatible in a two-way tank-mix with one of the under-named approved formulations;
the efficacy of the mixtures upon weeds has not been verified. Follow the Directions for Use of the other product
in the tank-mixture together with those of this label.
Glyphosate

SPRAY DRIFT/GROUND CONTAMINATION
Avoid damage by drift onto broad-leaved plants outside the target area or onto ponds, waterways and ditches.
Take especial precautions to prevent drift onto any susceptible crop. All broad-leaved crops such as tomatoes,
lettuce, oilseed rape, vegetables, turnips, swedes, sugar beet, peas, beans, glasshouse crops, fruit, ornamentals
etc. are susceptible by spray contact or ground contamination. Do not spray in windy weather. Emptying or
cleaning of spray machinery must not be conducted on cropped land or land intended for cropping.
NON-TARGET SPECIES
It is important that spray does not come into contact with the foliage or roots of susceptible trees and shrubs in
the vicinity of the area of application. Any use in the vicinity of trees or shrubs where contact of the spray with the
leaves, bark or underlying roots might occur must be at the users’ risk. However species differ in their
susceptibility to Clayton APT and the following tables are a guide to species susceptibility. If it is necessary to
spray in the vicinity of the more tolerant species, users are advised to treat around a small number of specimens
of all species to be encountered initially and observe for any adverse effects over a full growing cycle at least and
verify for themselves the safety or otherwise of the treatment before proceeding to treat larger areas.
Particularly susceptible species
Do not spray in the vicinity of the species at any time.
Chinese Privet (Ligustrum sinense)
Japanese Privet (Ligustrum japonicum) Common Privet (Ligustrum vulgare)
Species tolerant of soil application but susceptible to foliar contact
Foliage may be particularly susceptible during periods of active leaf growth; it is essential to protect specimens
from all leaf contact with the spray.
Border Forsythia (Forsythia intermedia)
Lombardy Poplar (Populus nigra cv .italica) Butterfly Bush (Buddleia davidii) London Plane (Platanus acerifolia) Cherry Laurel (Prunus laurocerasus) Northern White Cedar (Thuja occidentalis) Orange Cotoneaster (Cotoneaster franchetii) Common Hazelnut (Corylus avellana) Horse Chestnut (Aesculus hippocastanum) Small-leaved Lime (Tilia cordata) Indian Bean (Catalpa bignonioides) Western Red Cedar (Thuja plicata) Lawson Cypress (Chamaecyparis lawsoniana)
Relatively tolerant species
Himalayan Birch (Betula utilis)

SUBSEQUENT USE OF TREATED AREAS
Clayton APT should not be applied to areas of land that may be required for the planting of trees or ornamental
plants or used for cropping.
WEED CONTROL
Clayton APT will control a wide range of weeds when used as directed but does not control:
Fat-hen

Consider an appropriate tank-mix partner herbicide for those weeds that are not controlled.
The long-term effect of Clayton APT pre-emergence or post-emergence in tank-mixture with glyphosate on
broad-leaved dock, common nettle, creeping thistle, mallows and ragwort is not known.
WEED RESISTANCE
This product contains flazasulfuron which is an ALS inhibitor, also classified by the Herbicide Resistance Action
Committee as ‘Group B’.
Use only as part of a resistance management strategy that includes cultural methods of control and does not use
ALS inhibitors as the sole chemical method of grass-weed control.
Strains of some annual weeds, e.g. black-grass, wild-oat 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. Guidelines have been produced by the Weed Resistance Action Group and copies are available from
the HGCA, CPA, your distributor, crop advisor or product manufacturer.
Elements of a weed resistance management strategy include:
 Applying Clayton APT according to the label instructions in conjunction with good spraying practice and under
 Avoiding the use of Clayton APT or any other ALS inhibitor group herbicide as the sole means of grass and broad-leaved weed control in successive years; use herbicides with different modes of action or if practicable use alternative methods of weed control.  Using mixtures of herbicides or sequences of herbicides with different modes of action e.g. for control of existing weeds apply Clayton APT in mixture with glyphosate.  Monitoring treatment efficacy and seeking professional advice if areas of poor weed control occur that appear
AFTER USE
THOROUGHLY CLEAN ALL SPRAY EQUIPMENT IMMEDIATELY AFTER USE, USING THE FOLLOWING
PROCEDURE:
1. Drain the tank completely. Wash the outside of the equipment with clean water.
2. Rinse the inside of the tank with clean water and flush through booms and hoses using at least 10% of the
spray tank volume. Drain the tank completely. 3. Half-fill the spray tank with clean water and add 2.6 litres of household ammonia (containing 9.5% ammonia) for each 100 litres of tank volume. Other ammonia solutions may be used as long as the final concentration of ammonia when diluted in the full tank is 0.25% w/v. Agitate and then flush the boom and hoses with the ammonia solution until ammonia solution is ejected from all nozzles. Completely fill the tank with water and agitate for 15 minutes. Flush the boom and hoses again and drain the tank completely. If it is not possible to drain the tank completely, step 3 must be repeated before going on to step 4. 4. Remove nozzles and filters and clean with ammonia solution of the same concentration (0.25%) as used to 5. Rinse the tank with clean water and flush through the boom and hoses using at least 10% of the spray tank volume. Drain the tank completely and allow the sprayer to dry. 6. Dispose of washings in a safe area upon the holding designated for the purpose. Do not spray onto land intended for cropping or bearing amenity vegetation.
