Guidance when knapsack spraying

View the industry code of practice for knapsack spraying:  'Best Knapsack Spraying practices'

View the  'five golden rules for the safer use of pesticides' or Download PPT (520 Kb)   Download zip file (310 Kb) 

View 'Efficient knapsack use' and learn how to maximise the benefits of pesticides and minimise the risks. Understand the importance of maintenance, calibration, best use and cleaning of knapsack sprayers and the role of nozzle types to achieve uniformity of spraying. Download PPT (665 Kb)   Download zip file (412 Kb)  

View the Flash movie of 'Good spraying practice'; learn why different classes of pesticides demand different types of spray deposit on target surfaces. Understand the need to follow label advice at all times; the correct use of personal protective equipment and why the weather - especially wind speed and direction matters. Learn why some sprays require small drops (with a higher risk of drift) and others can tolerate larger drops with lower risk of drift. And more..

Correct use of Personal protective equipment (PPE) - learn what to wear in order to avoid exposure when loading or using sprayer or cleaning equipment and disposing of used containers. Download PPT (2385 Kb)   Download zip file (2034 Kb)   

Mixing and preparing CPPs for use - learn how and where to mix pesticides safely and the sequence to use with differing formulations. Download PPT (1193 Kb)   Download zip file (980 Kb)  

Disposal of empty containers - learn how to clean emptied pesticide containers, where to use the rinsates, make cleaned containers unfit for use and where to dispose them safely. Download PPT (419 Kb)   Download zip file (255 Kb)

Portable Spraying equipment. Find out about the range of sprayer design types available and how the wide range of spraying uses are met. Know the importance of independent guidelines (e.g. FAO), that can help you choose the best, safest and most durable sprayer for your needs. Understand the importance of sprayer maintenance and identify key components that need checking and or replacement. Study how side lever, motorised, compression, mistblowers and spinning disc (CDA) sprayers work. Download PPT (1868 Kb)   Download zip file (1025 Kb)  

Nozzle selection and their optimised use - learn the role of nozzles, the range of types, how they are made and function, their colour coding, flow rates manufactering material, wear rates and more. Know how to choose volume rates, drop size, their movement to or through crop canopies, learn about target surfaces retention and drift and operator exposure. Consider the importance of pressure control on the spray liquid in the nozzle and devices that help minimise fluctuations in output. Download PPT (1990 Kb)  Download zip file (1156 Kb)   

Calibration of hand held sprayer equipment - learn about the calibration methods, spraying speed, nozzle choice, spraying pressure, water volume rates and the operator's spraying method. Download PPT (1173 Kb)   Download zip file (647 Kb) 

Record keeping - learn of the importance of records; for crop assurance schemes as well as for your own assessment of input costs and benefits.  Know why records of pesticide use (where, when, how sprayed, weather conditions, accidents and incidents whilst spraying) are essential for best spraying practices today. See how to keep records of pesticides in store, what has been used, what remains, who sprayed which crop with what equipment.  Download PPT (379 Kb)   Download zip file (85 Kb)

Learn about spray distribution and water-sensitive paper, where to use water-sensitive paper,  how to evaluate spray deposit, and droplet sizing.

Learn how spray management valves enable a nozzle to emit the correct flow of spray solution by having a constant spray pressure at the nozzle itself.
