Classification and Security

Hazard Statements	H302: Harmful if swallowed H315: Causes skin irritation H319 Causes serious eye irritation H332 Harmful if inhaled. H335: May cause respiratory irritation H410: Very toxic to aquatic life with long lasting effects
Precautionary Statements	P261: Avoid breathing mist P264: Wash hands and face thoroughly after handling P280: Wear protective gloves/ protective clothing/ eye protection/face protection P337+P313: If eye irritation persists: Get medical advice/ attention P391: Collect spillage P501: Dispose of contents/container to a licensed hazardous-waste disposal contractor or collection site except for empty triple rinsed clean containers which can be disposed of as non-hazardous waste
Other Restriction of Use	Application must only be made to enclosed professional sports turf where access by wildlife is extremely restricted. Horizontal boom sprayers must be fitted with three star drift reducing technology for all uses. This product must not be applied via hand-held equipment. Buffer zones greater than 5m are NOT eligible for buffer zone reduction under the LERAP scheme.
Personal Protective Equipment	Engineering control of operator exposure must be used where reasonably practicable in addition to the following personal protective equipment: Operators must WEAR SUITABLE PROTECTIVE GLOVES AND FACE PROTECTION (FACESHIELD) when handling the concentrate. However, engineering controls may replace personal protective equipment if a COSHH assessment shows that they provide an equal or higher standard of protection

Application Advice

Application Advice

Tank mixing	Apply ASCERNITY at 3 litres per hectare in 125-500 litres water per hectare. For spot treatments, use 30 ml ASCERNITY per 10 litres water per 100 sq. metres. Apply as a preventative spray when conditions become favourable to disease development.
Tank mix preparation	For mixing sequence refer to the GreenCast Art of Application: www.wales tank mixing sequence.
Implementation particular terms	Application must only be made to enclosed professional sports turf where access by wildlife is extremely restricted. HORIZONTAL BOOM SPRAYERS MUST BE FITTED WITH THREE STAR DRIFT REDUCING TECHNOLOGY for all uses. Low drift spraying equipment must be operated according to the specific conditions stated in the official three star rating for that equipment as published on HSE Chemicals Regulation Division’s website. These operating conditions must be maintained until the operator is 30m from the top of the bank of any surface water bodies. For all applications, avoid spraying within 10m of unmanaged land (including rough grassland) to reduce effects on non-target insects or other arthropods. Buffer zones greater than 5m are NOT eligible for buffer zone reduction under the LERAP scheme. This product must not be applied via hand-held equipment.
Mixing and spraying	Tractor-mounted/trailed sprayers: Make sure the sprayer is set to give an even application at the correct volume and an even deposit. Half fill the spray tank with the required volume of clean water and start agitation. Add the required amount of ASCERNITY to the spray tank. Agitate the mixture thoroughly before use and continue agitation during spraying. Thoroughly wash all spray equipment with water immediately after use. Effectiveness using three star drift reduction technology may be reduced. After spraying, thoroughly wash out sprayer according to manufacturer’s guidelines and dispose of washings and clean containers according to local Code of Practice and local water authority guidelines.
Water volume	ASCERNITY is recommended to be applied in 125-500 litres water/ha using vehicle mounted/trailed sprayers.

Type	Title	Description
To preserve the environment	Prevent spray drift.	To protect aquatic organisms, respect an unsprayed buffer zone to surface water bodies as specified for the crop. HORIZONTAL BOOM SPRAYERS MUST BE FITTED WITH THREE STAR DRIFT REDUCING TECHNOLOGY for all uses. Low drift spraying equipment must be operated according to the specific conditions stated in the official three star rating for that equipment as published on HSE Chemicals Regulation Directorate’s website. Maintain three star operating conditions until 30 m from the top of the bank of any surface water bodies. Crops/situations with >5m buffer zone: Since there is a risk to aquatic life from use, direct spray from horizontal boom sprayers must not be allowed to fall within the distance specified for the crop of the top of the bank of any static or flowing waterbody or within 1m of the top of a ditch which is dry at the time of application. Spray must be aimed away from water. Buffer zones must be measured in accordance with the guidance set out in the booklet ‘Local Environment Risk Assessment for Pesticides - Horizontal Boom Sprayers’ available from HSE Chemicals Regulation Division’s website and any amendments made to it. The results of the LERAP must be recorded in written form and must be available for a period of three years for inspection to any person entitled to exercise enforcement powers under or in connection with the Plant Protection Products Regulations 2011 or the Plant Protection Products (Sustainable Use) Regulations 2012. (An electronic record will satisfy the requirement for a written record, providing it is similarly available for inspection and can be copied). Do not contaminate water with the product or its container. Do not clean application equipment near surface water. Avoid contamination via drains and amenity areas.
