Water UK update Activity (Page 12) Using information provided by your presenter, list the steps that can be taken to avoid risks to water when using Propyzamide.
Make a list in your workbook.
Water UK update • Take care when filling and cleaning the sprayer. • Use 6m grass buffer strip, or 5m no-spray zone, beside water courses. • Discuss cultivation and spray timing with your BASIS registered adviser. • Manage soils and tramlines to avoid surface run-off or erosion.
Water UK update • Do not apply when soils are cracked, dry or saturated. • Do not apply propyzamide if heavy rainfall is expected within 48 hours.
Professional use and amateur use products Amateur use: • Users of pesticides which are approved for amateur use do not require specific training or a certificate of competence. • These are often supplied ready to use.
Professional use and amateur use products Professional use: • Pesticides, such as those used on farms, or in public areas are approved for use in much larger commercial situations. • The labels of these 'professional' products can be more complicated, and by law must only be used by those who have had the appropriate training and hold a certificate of competence.
Professional use and amateur use products Professional use: • Professional products should never be used by the untrained amateur gardener.
Professional use and amateur use products Activity (Page 13) Can amateur (home/garden) products be used in areas outside of this area, for example in areas generally accessed by the public? Give reasons for your answer. Answer: YES
Professional use and amateur use products Feedback: Pesticide products are expected to be used in accordance with their authorisation and therefore only used in the home garden. However, this does not prevent the use of home garden products in other situations such as parks and cemeteries if all the conditions of that product's authorisation can be complied with.
Professional use and amateur use products Activity (Page 14) Can a professional product be used in a home garden situation? Give reasons for your answer. Answer: YES
Professional use and amateur use products Feedback: It may be possible for a professional pesticide to be used in what would normally be considered to be an 'amateur' situation (such as the home or garden or on an allotment). However, you will need to be able to answer 'yes' to the questions on the next slide.
Professional use and amateur use products • Will the conditions of authorisation of the pesticide be followed? • If a certificate of competence is needed, does the user have one? • Will reasonable precautions such as those given in the Code of Practice for Using Plant Protection Products and the instructions on the product label be followed?
Pesticide application equipment – planters/cultivators The following slides cover the operator certification requirements for cultivator/planter mounted pesticide application equipment. The aim of PASC Unit 233 is to qualify the operator to operate all of the cultivator/planter mounted pesticide applicators by undertaking one assessment only.
Pesticide application equipment – planters/cultivators Cultivator/planter mounted in-furrow liquid application (e.g. boom or band application of fungicide):
• PASC Unit 233 • PA2A (if it is a horizontal boom)
Pesticide application equipment – planters/cultivators Cultivator/planter mounted powder application:
• PA12 – if mechanical • PASC Unit 233 – if mechanical • PA6MC (or old PA6D) if applying by hand
Pesticide application equipment – planters/cultivators Cultivator/planter mounted granular application:
• PASC Unit 233 • PA4G (or old PA4)
Pesticide application equipment – planters/cultivators Cultivator/planter mounted slug pellet application:
• PASC Unit 233. • PA4S (or old PA4).
Pesticide application equipment – planters/cultivators Please note that the specific applicators that are assessed for the PASC Unit 233 are not transferable. Operators achieving PA2 prior to June 1994 will also be qualified in respect of PA4 and PA6.

National Sprayer Testing Scheme (NSTS) update. Analysis of most common faults (2019) • 5 of the faults relate to leaks and drips • 1 of the faults (hose condition) will become a leak or drip So 60% of faults are all attributed to this one similar issue!
National Sprayer Testing Scheme (NSTS) update. Analysis of most common faults (2019) These are all relatively simple, straightforward and quick to rectify, and should be done when they occur to ensure environmental problems are avoided whenever possible.
National Sprayer Testing Scheme (NSTS) update. Activity (Page 19) What is the most effective method of checking for leaks on your sprayer? Record your suggestion in your workbook.
Answer: Run the sprayer at higher than ‘normal’ working pressure (e.g. 5 bar) and check for leaks.
National Sprayer Testing Scheme (NSTS) update. How many of you use this method to check for leaks? Please discuss. Quite often, it seems faults that have recently occurred before a test are left for the machine examiner to rectify at the time of the test. So the NSTS test is also a service on the machine, which should not be the case.

Emergency spill kits Spillages can be a major cause of long-term environmental contamination as well as causing risks to personal health and safety. It is important that chemical spillages are dealt with quickly and efficiently in order to avoid injury and possible legal action.
Emergency spill kits How many of you carry a spill kit on the sprayer/prime mover?
Emergency spill kits • Always plan for the worst-case scenario and make sure that your spill kit can deal with the full range of pesticides. • Remember that the spill could be concentrate or dilute and it could also be liquid, powder or granules.
Emergency spill kits Activity (Page 21) List the equipment which could be required to deal with a pesticide spill. Record your answers in your workbook. Feedback: Suggestions please‌..
Emergency spill kits • PPE – Coverall, face shield, nitrile gloves, overshoes, respirator FFP3. • Absorbent materials – paper towels, spill pads, spill socks, granules. • Drip tray. • Disposable bags with tape or twist ties. • Shovel and polypropylene broom. • Labelled and secure container for waste.
Emergency spill kits
Emergency spill kits Disposal of any waste materials which have been collected must always be dealt with by a Reputable Licenced Waste Disposal Contractor. Always ask for a Waste Transfer Note as your proof of legitimate disposal.

Grain store treatments Store preparation and monitoring Grain store preparation is a crucial job, and must be done meticulously to ensure that grain is kept in the best possible condition, and has the least chance of being destroyed by insects.
Grain store treatments Store preparation and monitoring Following thorough store cleaning and treatment (pre storage), place insect attractant bait bags and check weekly by shaking over white paper. Take remedial action if insects identified.
Grain store treatments Store preparation and monitoring Once the store is filled with grain, Pitfall Insect Traps can be used to detect the presence of insects. Pitfall Traps are used in pairs, with one at the surface and one placed approximately 815cm down into the grain.
Grain store treatments Methods of application and certification requirements Activity (Page 25) Using information supplied by your presenter, complete the table in your workbook detailing operator certification requirements.
Grain store treatments Methods of application and certification requirements Application method: Operator certification: Hand-held (knapsack) sprayer Operating Pedestrian Hand Held Applicators Fitted with Hydraulic Nozzles or Rotary Atomisers to Apply Pesticides to Land (PA6A) Mist blower Applying Pesticide Mists, less than 100 Microns VMD Indoors (PA9A)

Grain store treatments Calculation of store area/volume Within your workbook you will find useful reference material relating to the calculation of the following: • Surface areas • Building volumes • Crop flow
Rodent control update More than 23,000 pest control technicians, gamekeepers and farmers have completed approved training courses and become certified as competent users.
There are 17 stewardship-approved farm assurance schemes whose 94,000 members are inspected against standards for rodent pest management.
Rodent control update During the first two years with all stewardship elements in place there have continued to be significant rodenticide residues found in Barn Owls, this is known as secondary poisoning.
Secondary poisoning is when a predator eats a dying rodent that has been poisoned, or a scavenger eats a dead carcase of a poisoned rodent and is affected.
Rodent control update The government is expecting lasting reductions in rodenticide residues carried by non-target wildlife. Without good evidence of this, further restrictions will be implemented.
Rodent control update Activity (Page 29) List some control methods which would form part of an Integrated Pest Management control programme for rodents.
Feedback: Suggestions please‌..
Rodent control update IPM control methods (in order): • Proofing buildings • Hygiene • Denial of food and water • Removal of harbourage • Trapping • Alphachloralose (anaesthetic - mice only)
Rodent control update IPM control methods (in order): • Gassing (rats only). • First Generation anticoagulants (warfarin, chlorophacinone and coumatetralyl). • Second Generation anticoagulants (brodifacoum, bromadiolone, difethialone, difenacoum, flocoumafen).
Rodent control update Remember the preferred order of control: Habitat management Âť Physical control Âť Chemical control 1 2 3

Licence requirements Trailer tests Width and speed limits Weight limits Vehicle roadworthiness
Road Traffic Law and Sprayers Within this section we will cover:
• Health and safety law • Mobile phones • Driver courtesy
Road traffic law and sprayers What licence do I need to drive a self-propelled sprayer on road? Machines such as telehandlers and selfpropelled sprayers are officially classed as agricultural machines and legally require a driver to have passed a category B (car) driving test. The minimum age at which a category B test can be taken, and a licence obtained is age 17.
Road traffic law and sprayers What licence do I need to drive a self-propelled sprayer on road? However, the passing of a category B test does not give a person aged 17 the ability to drive all agricultural machines such as sprayers straight away. There are age-based restrictions to consider up to the age of 21 yrs.
Road traffic law and sprayers What licence do I need to drive a self-propelled sprayer on road? Vehicle weights and age requirements are: • 3.5 tonnes limit between ages 17 and 18. • 7.5 tonnes limit between ages 18 and 21. • Vehicles over 7.5 can only be driven under a category B licence legally on road by persons aged 21 years or over.
Road traffic law and sprayers What licence do I need to drive a sprayer towed by a tractor? Option 1: • If the F (tractor) driving test is passed a 16 year old can legally drive an agricultural tractor and trailer on the road. • At age 16 there is a 2.45m width restriction. • At age 17 there are no width restrictions.
Road traffic law and sprayers What licence do I need to drive a sprayer towed by a tractor? Option 2: • The entitlement to drive a tractor is automatically awarded to holders of a category B (car) licence – in other words the ability to drive an agricultural tractor comes automatically when a category B test is passed.
Road traffic law and sprayers Trailer tests - tractors Agricultural tractors and trailers are treated as one unit. This means that the entitlement to drive a tractor automatically includes the entitlement to drive a tractor and trailer combination. No additional testing or license qualifications are needed.
Road traffic law and sprayers Trailer tests – other agricultural machines e.g. self-propelled sprayers The general rule is that a category B driving licence allows holders to drive agricultural machines and a towed trailer weighing a maximum of 750kgs laden weight.
Road traffic law and sprayers Trailer tests – other agricultural machines e.g. self-propelled sprayers To tow a trailer over 750kg behind an agricultural vehicle an additional licence qualification is needed (category E – trailer test). To gain a category E licence entitlement an additional test must be taken and passed.
Road traffic law and sprayers Width and speed limits The speed limit for agricultural vehicles varies according to the vehicle type and the width of the vehicle.
Road traffic law and sprayers Width and speed limits Activity (Page 37) Using information from your presenter, please complete the table in your workbook.
Road traffic law and sprayers Width and speed limits Tractor type:

Road traffic law and sprayers Weight limits The weight limit for an agricultural tractor/trailer combination is 31 tonnes. Within the overall weight limit of 31 tonnes the weight of a laden trailer can be no more than 18.29 tonnes.
Road traffic law and sprayers Weight limits Towed sprayers are classed as a towed appliance up to a weight of 14.23 tonnes. Over that weight limit towed sprayers are treated in the same way as trailers. This means that the maximum permitted weight of a tractor and sprayer combination on road is 31 tonnes and the weight of the sprayer can be no more than 18.29 tonnes.
Road traffic law and sprayers Vehicle roadworthiness The main purpose of agricultural vehicles is to perform agricultural operations on field and so it is considered that it is not appropriate to have the same high level of regulation as HGVs. Agricultural vehicles are not required to have annual MOTs.
Road traffic law and sprayers Vehicle roadworthiness However, the law says that all agricultural vehicles must be safe and roadworthy every time they are used e.g. brakes must work, lights must work etc.
Road traffic law and sprayers Vehicle roadworthiness Drivers who take unroadworthy vehicles on road can face enforcement action and be sanctioned by penalty point, fines, and imprisonment for serious offences. Persons who cause or permit unroadworthy vehicles on road can face similar sanctions.
Road traffic law and sprayers Health and safety law Under health and safety law employers have a duty to take reasonable steps to ensure the health and safety of people who work for them and anyone else who may be affected by their business operations. Employees have a duty to take reasonable steps to ensure their own safety and the safety of others who may be affected by their work activities.
Road traffic law and sprayers Health and safety law Employers have a duty under the Provision and Use of Work Equipment regulations (PUWER).
Activity (Page 38) List the duties of the employer under PUWER. Record this information in your workbook.
Road traffic law and sprayers Health and safety law Employer obligations – PUWER: • Ensure that equipment provided for work is suitable for the purpose intended. • Persons using equipment are trained and competent. • Equipment is well maintained.
Road traffic law and sprayers Mobile phones The use of mobile phones while driving is banned. Offences attract fines of ÂŁ200 and 6 penalty points per offence.
12 penalty points results in the loss of a driving licence.
Road traffic law and sprayers Driver courtesy Driver courtesy is essential to establish good relationships with other users of rural roads and with rural residents.
Road traffic law and sprayers Driver courtesy Important points to remember are: • Adjust speed to the road conditions at the time. A speed limit is not a target that must be reached at all times but something to comply with if the conditions are right.
Road traffic law and sprayers Driver courtesy Important points to remember are: • Do not use mobile phones as these are a cause of driver distraction and given the high visibility of drivers in agricultural vehicles noticed quickly by other road users. • Take care to protect the road environment by not driving on kerbs, banks of ditches etc.
APPLICATION AND TECHNOLOGY
Workbook Page 40
Application and Technology Within this section we will cover: • Effective sprayer cleaning • Sprayer filling • Spray droplet size and volume • Nozzle spacing (50cm vs 25cm) • Spray Assist mobile phone/tablet application • Farm Sprayer Operator of the Year (FSOOTY) competition
Effective sprayer cleaning Effective sprayer cleaning avoids risks to other crops sprayed and ensures the sprayer is always ready for the next job. This is particularly important after using herbicides where even small traces can damage sensitive crops. Always check the label as the product may require special cleaning procedures.
Effective sprayer cleaning Activity (Page 41) How do you ensure your sprayer is clean prior to moving on to a different crop (e.g. spraying oilseed rape following controlling brassica type weeds in cereals)? Feedback: • Your suggestions please‌..
Effective sprayer cleaning Recommended cleaning procedures are contained within your workbook. The best practice guide (contained within the workbook annex) also provides further information.
Effective sprayer cleaning Activity (Page 43) Please list the key areas (hot spots) where spray solution can remain following the initial clean. Record your answers in your workbook. Feedback: • Your suggestions please‌..
Workload planning to minimise cleaning It is always good practice to carry out a water rinse after every application is completed. However, by planning your order of spraying you may be able to reduce the frequency of thorough sprayer cleaning.
Workload planning to minimise cleaning Activity (Page 44) Please suggest the most efficient order to carry out the following spraying jobs to minimise the need to carry out thorough sprayer cleaning. Please indicate if a wash is required between jobs and specify the type of wash (e.g. water rinse or cleaning agent).
Workload planning to minimise cleaning Spray jobs (1):
• • • •
Autumn stubbles – glyphosate Winter oilseed rape – graminicide Winter wheat (late sown) – pre-em herbicide Winter wheat (early sown) – post-em BLW herbicide
Workload planning to minimise cleaning Feedback: • Your suggested spray job order please‌..
Workload planning to minimise cleaning Spray jobs (2):
• Pre-sowing – glyphosate • Winter oilseed rape – fungicide • Winter wheat – Fungicide and SU containing herbicide • Winter oats – plant growth regulator • Winter barley – wild oat herbicide
Workload planning to minimise cleaning Feedback: • Your suggested spray job order please‌..
Sprayer filling Here are some useful reminders regarding sprayer filling: • Always ensure the sprayer is thoroughly clean before starting – as there may be residues of incompatible products from the previous job. • The sprayer tank must be at least half full of water before you start adding products.
Sprayer filling Here are some useful reminders regarding sprayer filling: • Always add water conditioning products to the tank first. • Add more water as products are added. • Allow one product to completely clear the induction bowl before adding the next product.
Sprayer filling Here are some useful reminders regarding sprayer filling: • Recirculate the spray solution and give cans an initial rinse. • Once all product is in the sprayer carry out the final can rinsing with clean water during the final top up. • Spray solution immediately.

Spray droplet size and volume The size of a spray droplet is usually a measurement of its diameter in microns. One micron = 1/1000 millimetre = 0.0001mm
There is a simple but important relationship between droplet size and droplet volume. This is known as the spray volume rule of eight.
Spray droplet size and volume The relationship between size and volume is cubic. Therefore, by halving the diameter of any given droplet, eight droplets would be needed to carry the same volume.
Spray droplet size and volume Activity (Page 46) How many 200-micron droplets would have the same volume as a 400-micron droplet? Answer: 8 If eight 200-micron droplets were halved how many 100-micron droplets would there be? Answer: 64
Spray droplet size and volume Activity (Page 46) Is a droplet with a diameter of 400 microns more likely or less likely to be retained on a leaf than a 200-micron droplet? Answer: less likely
Spray droplet size and volume Activity (Page 46) Is a droplet with a diameter of 400 microns more likely or less likely to drift than a 200micron droplet? Answer: less likely
Spray droplet size and volume Volume Median Diameter The term Volume Median Diameter is used as a method for quantifying the type of droplet spectrum a particular nozzle produces.
Spray droplet size and volume Volume Median Diameter The term is defined as the droplet size at which 50% of the total sprayed volume is made up of droplets larger than the median and 50% of the total sprayed volume is made up of droplets smaller than the median.

Nozzle spacing (50cm vs 25cm) When purchasing a replacement sprayer there are many choices to be made one of which is “what nozzle spacing do I go for?” For quite some time sprayers have been sold with standard 50cm nozzle spacing which when used with 110˚ fan nozzles at 50cm above the target will give the correct coverage.
Nozzle spacing (50cm vs 25cm) There is now an option to go for 25cm nozzle spacing, but are there any benefits from this, or is it just an excuse to get the farmer/contractor to spend more money?
