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.

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 coapplied 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.
Avoid overdosing. Extreme care must be taken to avoid drift onto desirable plants such as crops, trees or ornamentals.
DO NOT apply within 12 months to soils which may later be used to grow crops or plants.
Treatment should NOT be made near to species that have been planted for less than 2 years.
DO NOT spray under windy conditions.

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.

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.
