Key points

• Simple tools and techniques are available to show spray applicators where the spray is landing and to allow the spray coverage to be measured. This allows for comparisons to be made and results to be kept for future reference.

• Making assessments of spray coverage allows the operator to compare the impact of changes to the sprayer set-up and to make adjustments to suit the target and the product where required.

• Keeping records of the spray coverage achieved using various set-ups will help spray operators to continually improve their sprayer set-up and the results of their spray applications.
