Introduction Course Outline Welcome to the 2019/2020 NRoSO annual training event. This year’s event is divided into four sections. The first section is Current Issues. This covers items that are in the national news and that we feel are worth discussing in more detail. This section will also cover specific local issues that your presenter will tailor to your geographical area or crop production system. The second section is Water Conditioning. In this section we will look at water quality, its effect on pesticide performance and the role of water conditioners. The third section is Sprayer Maintenance. In this section we will look at sprayer routine maintenance and filtration. The final section is Technology and Top-Tips. In this section we will look at application technology and a collection of top tips from Farm Sprayer Operator of the Year (FSOOTY) finalists.

Codes of Practice and Legislation Government Departments have produced guidance to help those working
SQC STANDARD 2.1
with pesticides meet the requirements of legislation. The Plant Protection Products (Sustainable Use) Regulations 2012 came into force on 18 July 2012, replacing the previous UK legislation governing the use of pesticides. Guidance on the safe use and storage of plant protection products already exists in the Code of Practice for Using Plant Protection Products. All professional users of plant protection products must follow the guidance. The Plant Protection Products (Sustainable Use) Regulations 2012 is a statutory instrument and has therefore been passed as legislation in the UK. However, there is often confusion regarding the legal status of the Code of Practice for using Plant Protection Products. • The code gives you advice on how to use
pesticides safely. • The code has a special position in law. If you follow its advice you will be doing enough to keep within the law. But you may be able to work in a different way from the code as long as that way is just as safe. • If you are prosecuted for not following the code, a court will find you guilty unless you can show that you have obeyed the law in some other way.
A new Code of Practice may be issued in due course. In the meantime, although some of the underlying legislative framework has changed, the general guidance contained in the existing code remains appropriate. 11

A few questions/activities based on the COP: 1.
When filling equipment, what height does the “Code of Practice” state you should not lift pesticide containers above?
2.
List three things that the Code of Practice states are dangerous practices (for the operator) when pesticides are being used:
3.
What are the minimum Personal Protective Equipment (PPE) requirements when handling a liquid concentrate?
4.
What do EN numbers on an item of Respiratory Protective Equipment (RPE) indicate?
5.
What does a coverall that is labelled as both Type 5 and Type 6 provide protection from?
6.
On most product labels the following statement appears. ‘However, engineering controls may replace PPE if a COSHH assessment shows they offer an equal or higher standard of protection.’ What might constitute an Engineering Control?

IPM Training/Certification At an agronomy level, BASIS courses/awards include reference to IPM practices. The awards are now titled with reference to IPM, e.g. BASIS Certificate in Crop Protection IPM. Linking Environment and Farming (LEAF) offer the LEAF BASIS ‘Introduction to IFM’ and LEAF Marque training. At operator/supervisor level, City & Guilds offer the Level 3 Award in Responsible Pesticide Management. This qualification is designed specifically for anyone who currently supervises or manages a pesticide team or wishes to develop their career further.
This qualification is split into four mandatory units: • Managing the Health, Safety and Welfare of Operators Applying Pesticides • Minimising the Environmental Impact of Pesticide Operations • The Selection, Storage and Effective Use of Pesticides • Integrated Pest Management (IPM) Growers are being urged to demonstrate IPM practices. Part of this qualification covers the principles, methods, implementation and effectiveness of IPM. For more information please visit www.nptc.org.uk and click on the 14

Products/Active Substances Update Glyphosate
SQC STANDARD 2.6 2.7
The current EU licence for glyphosate expires on 15 December 2022. A meeting of EU member state representatives in April decided on how an application for the reauthorisation of the active substance glyphosate will be dealt with in the coming years. Representatives endorsed a commission proposal for the relevant authorities of four member states to review the application to re-authorise glyphosate in the EU when it is forthcoming. The four that will jointly carry out the review are France, Hungary, The Netherlands and Sweden. The decision states that the regulatory authorities of these countries must “endeavour to reach consensus during the evaluation.�
Chlorothalonil Chlorothalonil, a highly effective multi-site fungicide that has been used across the world for over 50 years, has been banned by the European Union. Draft regulation for the non-renewal of the approval of the active was tabled at a meeting of an EU Standing Committee on 21-22 March and was supported by a majority of Member States in a subsequent vote. Key dates: Sale and supply of products containing chlorothalonil ends on _____________ The latest date for disposal, storage and use of existing stocks is ____________ The loss of chlorothalonil will come as a huge blow to farmers as our climate makes our crops particularly susceptible to fungal diseases. Chlorothalonil, with its multiple modes of action, plays a vital strategic role underpinning control and resistance management of fungal diseases in UK crops. As a consequence there will be a significant increase in the risk of rapid development of resistance to other fungicides.

Chlorpropham (CIPC) Chlorpropham (or CIPC) is being withdrawn in Europe on 8th January 2020 with a short use-up period to follow. CIPC is widely used as a sprout suppressing agrochemical applied to stored potatoes.
SQC STANDARD 2.6 2.7
Treatment of potato stores involves, in most cases, application of CIPC as a hot fog which is introduced into the storage building under pressure using specialist thermal fogging equipment. Best practice requires use of the store ventilation system to help to distribute this fog evenly throughout the crop to optimise the suppressant’s activity and to minimise residues. An additional problem is that CIPC remains present in the construction material of potato storages. Even after industrial cleaning, CIPC persists in the building, and the Maximum Residue Limit (MRL) is 0,01ppm. Even years later, CIPC can migrate from the building materials to the potatoes stored in that building. And should CIPC be found in a sample, all potatoes in the store would have to be destroyed.
Ethoprophos Ethoprophos, the active substance in Mocap 15G, has been banned by the European Commission. Mocap 15G is a popular insecticide and molluscicide among UK potato farmers and its loss will seriously deplete their crop protection toolkit. The decision to ban Ethoprophos was made at a recent meeting of the Standing Committee on Plants, Animals, Food and Feed after the Commission had put forward the draft regulation for a vote. The published Commission regulation banning Ethoprophos gives a maximum date of until 21 September 2019 to sell or distribute existing stocks of product, and a maximum use up date for products of 21 March 2020. Member States are left to set their withdrawal dates within these boundaries but the UK has yet to publish its withdrawal notice for Mocap 15G.

Reduced Volume Spraying
2.8
What is a Reduced Volume Application? It is when the concentrated product is applied with a lower volume of water than the product label recommends for the dose stated.
2.9
2.10
What are the risks associated with Reduced Volume Spraying? • Smaller droplet size (finer spray quality). • Increased drift potential. • A more concentrated solution, possible increased risks to people and the environment. In the following example, applying 3 l/ha of product in 100 l/ha would be a ‘Reduced Volume Application’. Dose Rate
Water Volume
3 l/ha
150-250 l/ha
However, applying 2 l/ha in 100 l/ha would not be considered a ‘Reduced Volume Application’ as the product has been reduced in proportion to the water volume. 150 l/ha ÷ 3 l/ha = 50 litres of water per litre of product. 2 l/ha x 50 = 100 l/ha How can we tell if we are allowed to make a ‘Reduced Volume Application’? With reference to the product label or relevant notice of approval, the following situations would mean that a ‘Reduced Volume Application’ could not be made. •
If it states that there is a minimum application volume, e.g. Dose Rate
Water Volume
3 l/ha
Apply in a minimum of 200 l/ha

Safety When Working Near Power Lines On average two people are killed and many more are injured every year when they come into contact with overhead power lines (OHPLs) during agricultural work. Contact with OHPLs can result in death by electrocution or serious injuries such as burns. If a piece of machinery or equipment gets too close to or comes into contact with an overhead cable, then electricity will be conducted through the machine or equipment to earth. It may also pass through anyone who is touching it. Electricity can arc, i.e. jump across gaps, so you (and your equipment or machinery) do not have to touch the lines to get a serious or fatal shock. Familiarise yourself with minimum clearances for power lines. Also be aware that power lines can ‘sag’ between poles – particularly during warmer weather.

Are You Qualified? We have covered operator certification in previous annual training events. In recent months there have been a significant number of enquiries regarding the certification requirements for operators of spraying bowsers. For operators who are transporting water in a tank /bowser with an attached mobile pesticide store, certification is not required. If operators are mixing and transferring pesticides then operator certification is required. The current certification requirements are as follows: • City & Guilds Level 2 Principles of Safe Handling and Application of Pesticides (PA1). • City & Guilds Level 2 Award in the Safe Mixing and Transferring of Pesticides (PA8). COP 3.3.3. You should make sure that all pesticides are safely transported to where they will be applied and stay safely stored at the site.

Water Conditioning Within the Water Conditioning section of this workshop, we will cover the following: Background to Water Quality Cation Exchange Alkaline Hydrolysis Source Water Quality Humectancy
29
Arable
Background Pure water is almost a myth. Reservoir and ground water supplies nearly always have something dissolved in them e.g. Carbonates, Bicarbonates, Sulphates or Nitrates of Calcium, Magnesium, Sodium, Potassium, Iron etc. This can influence the following: • hardness • pH • taste In this section we are going to look at the effects that water quality can have on the effectiveness of the overall spray solution.
Cation Exchange A characteristic of hard water is the high proportion of charged cations (dissolved minerals) that affect the performance of agrochemicals by locking up a proportion of its active ingredients. These cations bind with some herbicides, including
This map does not account for borehole sources which can be incredibly hard (>600ppm CaCO3).
glyphosate. These ‘bound’ herbicide compounds are unable to bind to the site of action in the target weed and the herbicide will be less effective. This is known as the cation exchange. The UK hard water area corresponds closely with the combinable crop production area where most PPPs are used. 30
Arable
The glyphosate molecule was originally patented as a descaling agent to be used for cleaning out drain pipes where mineral deposits of calcium, magnesium and iron accumulate. As glyphosate is a chelator it will grab onto these metal ions and remove them. When glyphosate is mixed into hard water (with high levels of Ca, Mg or Fe) it will grab onto these metal ions. The result is a strong complex which is not bio-available. Only the remaining unbound glyphosate is fully available to act as a herbicide. Solutions If Cations in the water are the problem, then the most effective solution would be to ‘negate’ the effect of the cations before adding the pesticide. This can be achieved by pre-conditioning the water with a product (e.g. X-Change). These products lock-up (chelate) the cations. The result is a spray solution in which all the herbicide is ‘active’. Activity: List the commonly used active substances/products that are affected by hard water. Record them below.
31
Arable
Alkaline Hydrolosis The pH of the spray solution can also affect chemical efficacy. Spray solutions with a high alkaline score will promote alkaline hydrolysis – where the molecules in the active solution become deactivated. Solutions By adding a water conditioner (e.g. X-Change) into the tank first, ahead of the agrochemical the pH is reduced to around 4.6 preventing hydrolysis from occurring. X-Change Concentration:

Alkaline degradation of pesticides is almost always associated with hard water. Many pesticides are less stable in alkaline solution. Activity: List the commonly used active substances/products that are affected by alkaline hydrolysis. Record them below.
32
Source Water Quality The source of water used for spraying can vary from farm to farm. The main sources are as follows: • Mains • Borehole • Reservoir • Rainwater Activity: Working in small groups, compare the hardness and pH of a range of water samples. Record your findings below.
Humectancy A further benefit of some water conditioners is their humectant properties. A humectant is a chemical agent which prevents the final part of the spray droplet from drying out totally. Only when moist can the active penetrate the plant’s cuticle. Humectant – increased time in % for uptake into the leaf
If the spray droplet dries out too quickly the active ingredient could precipitate into solids which will not be able to penetrate the leaf cuticle, particularly in hot conditions.
33
Arable
Summary Water conditioners do not directly enhance the performance of an agrochemical, but by improving the properties of water they allow the active ingredient to perform as it is expected to do so. Where a water conditioner is not used its performance can be impaired as a result. It is important that water conditioners are added to the tank before the pesticide. The correct order for filling the sprayer when using a ‘Cation Complexer’ water conditioner such as X-Change is as follows:
It is important to note that water conditioners are not classified as adjuvants or pesticides as they have no inherent pesticide activity.

Sprayer Filtration
2.19
Filters are an important part of the sprayer. They are there to protect many components of the sprayer and aid towards accurate application of plant protection products.

2.20
The general rule for checking the mesh size of the filters is the coarsest filter will be located at the suction end progressively getting finer through the system down to the finest filters at the nozzles. Filter related troubleshooting Activity: Please complete the table below showing the causes and corrective action for each of the filtration problems. Problem

Cab Filtration Are you sufficiently protected from chemical vapours when in your sprayer cab? Nanoparticles, being small in size (10 – 100 nm), can be absorbed through the body’s airways, the skin and the alimentary canal and then spread throughout the body by circulating blood. To prevent any risk to the machine operator’s health, highly effective filtration of the cab air is vital. EU regulation (last revised in January 2018) sets-out specific standards for cabs on agricultural equipment to protect the operator from hazardous substances. This includes plant protection products. Categories of filtration are as follows: • Category 1 – no defined level of protection against hazardous substances • Category 2 – protection against dust • Category 3 – protection against dust and aerosols • Category 4 – protection against dust, aerosols and vapour It is mandatory for any machine applying plant protection products to have Category 4 filtration. Dusts, aerosols and gaseous contaminants that arise as a result of using toxic substances are not permitted to enter vehicle cabins. There are a number of self-propelled sprayer manufacturers offering Category 4 as a ‘standard’ fitment. However, many tractor cabins are built to Category 2 standards. Some manufacturers offer an option to upgrade but not always to the highest level of filtration. If you’re unsure about the level of protection offered by your cabin, you should speak to your dealer. What options are there for increasing the level of cabin protection? Existing cabin filters can be upgraded. This does rely on being able to maintain suitable cabin pressure. Cabins have to be over pressured as internal cabin pressure is important to minimise the risk of dirty air being able to flow-in. 42
Arable
Some manufacturers are unable to increase protection standards due to a low internal cabin pressure. This is mainly due to the number of air gaps (e.g. cable routing etc.). To be able to achieve Category 4 filtration, activated and impregnated carbon filters (ABEK) are required. Active carbon dust (originating from peat, coal and coconut shell) has an enormous surface area and can therefore absorb organic substances. Inorganic fumes are collected with special impregnated coals. To this activated coal a chemical substance is added, to collect these fumes by using chemisorption (instead of adsorption). EN12941 provides a clear classification of the various chemical substances and their adsorption and chemisorption requirement. • A: Organic vapours and gases • B: Inorganic vapours and gases • E: Acid gases • K: Ammonia compounds Remember….. not all cabins are able to be upgraded to Category 4 filtration and you should always check with the manufacturer or dealer. A cabin filtration system can be retrofitted. Some of the aftermarket systems are designed to be fitted externally (e.g. on cabin roof) whereas some can be integrated into the cabin roof.

SQC STANDARD 2.8 2.9
4 Star Drift Reduction Nozzle Rating The star-rating classification originally included 1, 2 and 3 stars, which relate to 25%, 50% and 75% drift reduction. It became clear, soon after this was introduced, that both equipment manufacturers and users were most interested in 50% and 75% levels of drift reduction, and 25%, or 1-star, was not seen as of value. As we have covered in previous annual training events, other European member states introduced higher levels of drift reduction in their schemes – 90% and 95% - and there has been pressure to follow suit. The UK has therefore now introduced a 4-star rating (90%) and the first 4-star ratings have been awarded in 2019. Nozzle

Closed Transfer System (CTS) – Update Testing is being carried out across the country for a closed transfer system
SQC STANDARD 2.8 2.9
which is being developed by Hypro. The system is based around the use of an ezi-connect cap. The aim is for all agrochemical manufacturers to use this cap, which is a key component of the system.
As with the majority of CTS units, the can is inverted and attached to the unit. A lever locks the can in place to avoid operator and environmental contamination. The product container contents can then be dispensed either in full or part with the aid of the vacuum created by the induction hopper venturi system. Clean water rinsing of fully dispensed containers can also be carried out whilst the container remains attached to the system. Your presenter will provide more details on this system. Please record any notes below:

Spot Spraying – Update As part of last year’s annual training event we covered spot spraying and the capabilities of chlorophyll sensing boom mounted technology. Kuhn, working in partnership with Carbon Bee, is developing a new sprayer mounted system that uses artificial intelligence to identify weeds within a growing crop.
The I-Spray system uses hyperspectral sensors to target the weeds. The images are processed by a computer, which sends a signal to open and close individual nozzles to spot-spray weeds. The goal is to develop a system that is accurate at speeds of up to 15km/hr.
The main advantage of the Carbon Bee-developed system is that plant protection products are only applied where they are needed. This could lead to up to 80% saving in chemical costs.

Carbon Bee agronomists are teaching the system to recognise a number of weeds.

injured when they come into contact with high voltage electricity.
This can have a far-reaching and devastating effect on family, friends and colleagues. Distractions, working long hours, rushing to get the job done, can all impact on how we work and our safety. Taking time to plan, being prepared and focusing on the ukpowernetworks.co.uk way we work can help keep us safe.
Where equipment or machinery is used near overhead power lines the risk must be considered and controlled in the interest of everyone. Know the location of overhead electricity power lines and underground electricity cables on your land prior to starting work Contact UK Power Networks for copies of plans showing where equipment is and mark this information on your farm map. Ensure everyone working on your land, visitors, contractors and casual workers, are aware of the location and voltages of the overhead power lines before starting work
For further advice and cable maps visit www.ukpowernetworks.co.uk/
Plan your work so it avoids high risk areas. You should manage the risks if you intend to work within a distance of 10m. Contact UK Power Networks for advice on shrouding or disconnections before starting work Assess your safe working clearances to overhead power lines. If in doubt, contact the electricity network operator Never stack anything directly under or near to overhead power lines Use alternative access points and routes to fields which avoid crossing under overhead power lines Find out the maximum height and vertical reach of all your machinery and equipment
NATIONAL POWER CUT HELPLINE
Train staff to be aware of the risks associated with overhead power lines and underground electricity cables Ensure everyone on site is aware of the national power cut and emergency number 105 and they have the number in their mobile phone

How can we help? If you work or live in the UK Power Networks area contact us or look on our website. We provide free information and advice about the precautions and safe working practices to be followed when working close to electrical equipment. Further advice and guidance is available from the Health and Safety Executive (HSE): GS6 - Avoidance of Danger from Overhead Lines HSG47 - Avoiding danger from underground services
What to do in an emergency If your machinery touches an overhead line:
• Stay inside the vehicle • Call UK Power Networks, dial 105 and call the emergency services
• Never assume electrical equipment
is dead, even if it is fallen or broken
• If it is not possible to stay inside
the vehicle JUMP WELL CLEAR - so that no contact is made between you, the vehicle and the ground at the same time. DO NOT CLIMB DOWN
• Run well clear making leaping
strides so that one foot is off the ground at all times
• Do not return to the vehicle.
Stay clear - keep everyone away until assistance arrives

The electricity network is designed to keep you safe. But how safe are you when you are working? UK Power Networks is the country’s biggest electricity distributor, making sure the lights stay on for more than eight million homes and businesses across London, the South East and the East of England. The safety of our customers and staff is our top priority. Overhead electricity power lines run across the countryside, supplying local communities with power. The wires can be on wooden poles as well as metal pylons and carry voltages from 230 volts (domestic supply) up to 400,000 volts. Depending on the voltage the wire will be at different heights above the ground. Overhead power lines should be 5.2 metres (17 feet) above the ground. However, live equipment fitted on poles may be as low as 4.3 metres (14 feet).
REMEMBER, ATTACHMENTS SUCH AS ARIELS CAN INCREASE THE FULL HEIGHT OF YOUR VEHICLE
Keep well away Electricity can kill You could be at risk when: • Using farm machinery such as combine harvesters, tractors and telehandlers • Loading or unloading vehicles • Using long objects such as irrigation pipes and ladders • Stacking materials • Using lorries, wagons or tipper trailers • Working in poor visibility
