What are Grandfather Rights?
Level 2 Award in the Safe Use of Pesticides Replacing Grandfather Rights What are Grandfather Rights? Under previous legislation, anyone born before 31st December 1964 did not need a Certificate of Competence (CoC) to apply a professional plant protection product (PPP). From 26th November 2015, EVERYONE will require a CoC to apply PPPs. Describe the reason for the qualification – it is for everyone previously covered by ‘grandfather rights’, using PPPs on their own or an employer’s land. To use PPP as a contractor you need other CoCs.

Introduction The qualification consists of one mandatory unit and three optional units: Mandatory: 051: The principles of safe handling and application of pesticides on own land Optional: 052: Hand held pesticide application on own land 053: Operating machines to apply pesticides to own land 054: Applying pesticides using other specific equipment or methods to own land Describe the qualification

Hand held pesticide application on own land
Unit 052 This section covers one optional unit: Hand held pesticide application on own land Explain this is one powerpoint of four – one for each unit.

Unit 052 The majority of this unit is practical: most outcomes and assessment criteria will be examined by observation, for example in the use of a Knapsack Sprayer. For some outcomes and assessment criteria the Assessor will ask questions to confirm your knowledge: this PowerPoint and your workbook will help you prepare for those questions. Explain this unit involves mainly practical activity However there are a lot of calculations, and this presentation and the workbook will help with these

Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) During your practical assessment you will be asked to: calculate the quantities required for the area you have just calculated, and a full tank The following slides take you through one method of calculating this. There are other methods you can use. As long as you can accurately calibrate the sprayer it does not matter which method you demonstrate to the Assessor. You will be asked to calculate the quantities required for the area calculated in 4.6 and a full tank The Assessor will require you to calculate the quantities of pesticide and water required (or if applicable the amount of pre-mix required) for the area, this will include: ● amount of water required for specified area ● amount of pesticide required for specified area ● amount of water required for a full tank ● amount of pesticide required for full tank or the amount of premix required This presentation shows one method of calculation. There are other methods you can use. As long as you can accurately calibrate the sprayer it does not matter which method you demonstrate to the Assessor.

1. The walking speed of the operator in km per hour (kph)
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) For this method there are three measurements to collect when calibrating a knapsack sprayer these are: 1. The walking speed of the operator in km per hour (kph) 2. The output per minute of the sprayer in litres 3. The width of each pass of the sprayer, commonly known as the bout or swath width in metres For this method there are three measurements to collect when calibrating a knapsack sprayer these are: 1. The walking speed of the operator expressed in kilometres per hour (k/ph) 2. The output per minute of the sprayer expressed in litres 3. The width of each pass of the sprayer, commonly known as the bout or swath width expressed in metres or part thereof. Put on your PPE Half fill the tank with water

Put on your PPE; half fill the tank with water:
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) Put on your PPE; half fill the tank with water: To Calculate operator walking speed – Measure a distance of 100 metres. Put the knapsack on your back and start pumping, walk at a steady walking pace, pumping the sprayer every few seconds to maintain constant pressure and flow from the nozzle. Time yourself in seconds. 1. To Calculate operator walking speed – Measure a distance of 100 metres. Put the knapsack on your back and start pumping, walk at a steady walking pace, pumping the sprayer every few seconds to maintain constant pressure and flow from the nozzle Time yourself in seconds (for greater accuracy you could take an average from 3 x 100 metre passes).

To calculate walking speed the calculation is: 360
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) To calculate walking speed the calculation is: 360 the time to travel 100m = speed in kilometres per hour if it takes 90 seconds to cover 100m the calculation would be: 90 = 4 km/h ‘360’ is a constant figure (3600 seconds in an hour) to enable the speed calculation to work!) 360 seconds = 1 hour To calculate walking speed the calculation is: 360 divided by the time to travel 100m = X kilometres per hour e.g. if the 90 seconds was taken to cover 100m the calculation would be: 360 divided by 90 = 4 k/ph (Note the ‘360’ is a constant figure, to enable the speed calculation to work)

2. To measure the output of the sprayer
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) 2. To measure the output of the sprayer – When the knapsack is up to pressure, release the trigger into an empty bucket for exactly 1 minute, pumping the sprayer every few seconds to maintain constant pressure. After a minute, measure how much water has been sprayed out via the nozzle in litres. e.g. a single nozzle sprayed out 1.2 litres in one minute 2. To measure the output of the sprayer – When the knapsack is up to pressure, release the trigger into an empty bucket for exactly 1 minute, pumping the sprayer every few seconds to maintain constant pressure and flow from the nozzle. After a minute, measure how much water has been sprayed out via the nozzle and express this in litres. e.g. a single nozzle sprayed out 1.2 litres in one minute (if you have a mini – boom the output is multiplied by the number of nozzles, e.g. for 3 nozzles the outputis 1.2 x 3 = 3.6 litres)

3. To ascertain the bout (swath) width –
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) 3. To ascertain the bout (swath) width – hold the lance at the appropriate height. spray onto a dry piece of concrete, paving or tarmac pump the sprayer every few seconds to maintain constant pressure and flow from the nozzle measure the width of the spray. e.g. bout or (swath width) 1.2 m 3. To ascertain the bout (swath) width – measure the bout or swath width by holding the lance at the appropriate height (which must be within the overall capabilities of the nozzle(s) fitted). This is easily done by spraying onto a dry piece of concrete, paving or tarmac whilst, pumping the sprayer every few seconds to maintain constant pressure and flow from the nozzle and physically measuring the width ofthe spray. e.g. bout or (swath width) 1.2 m

To calculate the output of the sprayer per hectare:
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) To calculate the output of the sprayer per hectare: 600 x output (l/m) = total output (l/ha) speed (k/h) x swath width (m) Note the ‘600’ is a constant figure you will use, like the ‘360’ in the speed formula: It converts litres per minute into litres per hour, and converts your total to a quantity per hectare. Total output = 600 x sprayer output divided by operator speed and divided by swath width

600 x 1.2 (output l/m) = 150 (volume l/ha )
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) Example : 600 x 1.2 (output l/m) = 150 (volume l/ha ) 4 (speed km/h) x 1.2 (swath width m) Note: The spray volume is actually the amount of chemical and water per hectare. So 5 litres of chemical per hectare in a minimum of 200 litres of water per hectare will actually be 5 litres of chemical and 195 litres of water to make up the overall 200 litres of spray per hectare. (check this against label recommendations) e.g. 600 x 1.2 Litres (Output) ÷ 4 KPH (Speed) ÷ 1.2 metres (Bout/ swath width) = 150 litres per hectare spray volume. Note: The spray volume is actually the amount of chemical and water per hectare. So 5 litres of chemical per hectare in a minimum of 200 litres of water per hectare will actually be 5 litres of chemical and 195 litres of water to make up the overall 200 litres of spray volume per Ha. If the spray volume is too low as defined by the product label (which may state apply 5 litres per hectare in a minimum of 200 litres of water per hectare) the nozzle may need to be changed to one that emits a higher volume to achieve the required spray volume to keep within the label recommendations and comply with legislation.

How much chemical concentrate do you put in a full knapsack?
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) How much chemical concentrate do you put in a full knapsack? Tank capacity (l) x dose rate (l/ha) = Amount of concentrate (l) Calibrated Spray Volume (l/ha) for a 15 litre knapsack, and a chemical which is applied at 5 l/ha and the calibrated spray volume is 200 l/ha 15 x 5 litres = litres ( 375ml) 200 How much chemical concentrate (at label dose rate per hectare) to put in a full knapsack? Tank capacity multiplied by the dose rate per hectare divided by the Spray Volume = Amount of concentrate in litres e.g. A 15 Litre knapsack and a chemical which is applied at 5 litres per hectare and the calibrated spray volume is 200 litres per hectare 15 litres multiplied by 5 litres divided by the 200 = litres

How much will one tank cover at this spray volume (l/ha)?
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) How much will one tank cover at this spray volume (l/ha)? spray volume = number of full tanks per hectare tank capacity e.g. 200 litres = tanks per hectare 15 one hectare (10,000 m2 ) Number of tanks per hectare e.g. 10,000 = 750m2 for each full tank 13.33 How much will one tank cover at this spray volume per hectare? Divide the spray volume by the tank capacity to get number of full tanks per hectare e.g. 15 litres divided by the 200 = number of tanks per hectare How many square metres will one single full tank cover? Divide the number of square metres for one hectare which is 10,000 by the number of tanks per hectare e.g. 10,000 divided by = 750m2 for each full tank

How much water and chemical concentrate is required?
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) How much water and chemical concentrate is required? Measure and calculate the area example: 25m x 8m = 200m2. Calculate the amount of water example: spray volume is 200 l/ha, dose rate is 5 l/ha Volume of spray x area = x 200 = 4 litres 10, ,000 How much water and chemical concentrate is required for the operation? 1. Measure the length and width of the area e.g. length 25 metres, width 8 metres 2. Calculate the area The formulae for calculating the area is: Multiply the length of the area by the width of the area e.g. 25m x 8m = 200m2 3. To calculate the amount of water (Assuming the spray volume is 200 litres per hectare and the dose rate is 5 litres per hectare) The formulae of calculating the amount of water is: 200 divided by 10,000 multiplied by the quantity of m2 that needs treating = how much water will be required for the area e.g. 200 divided by 10,000 multiplied by 200 = 4 litres of water

5 x 200 = 0.1 litres (100ml) of chemical concentrate
Outcome 4. Be able to prepare and calibrate a hand held pedestrian applicator Assessment criterion 4.7 Calculate the quantities of pesticide and water required (or amount of premix required) calculate the amount of chemical concentrate example: spray volume is 200 l/ha, dose rate is 5 l/ha Dose rate (l/ha) x area (m2) = chemical concentrate required 10,000 x 200 = 0.1 litres (100ml) of chemical concentrate You need 0.1 litre (100ml) chemical in 3.9 litres water To calculate the amount of chemical concentrate required Dose rate ÷ 10,000 x area m2 that needs treating = how much chemical concentrate will be required for the area e.g. 5 ÷ 10,000 x 200 = 0.1 litres (or 100ml) of chemical concentrate Trouble shooting! Assuming that your measurements of the site were correct and your calibration calculations were correct: ● if you have mixed pesticide left over, then; the area was likely to be smaller than you calculated, or you missed bouts (swaths); or ● If you run out of spray volume before you have covered the entire area, you will have applied too much by perhaps walking too slowly or overlapping bouts (swaths)
