The National Sprayer Testing Scheme (NSTS) is a VI Scheme.
     NSTS is the National Sprayer Testing Scheme for the UK.  NSTS tested sprayers are a requirement of many UK farm assurance schemes and supermarket protocols as well as satisfying the sprayer testing requirements of the Sustainable Use Directive. 

NSTS is a managed by the Agricultural Engineers Association for the VI.

Visit the NSTS website where you can find our more about NSTS and how to book your test.

Remember all pesticide application equipment now needs to hold a valid test certificate.  This includes trailed, mounted and self-propelled sprayers as well as foggers, misters, granular and slug pellet applicators. 

Hand-held pedestrian operated equipment, such as knapsacks, does not need to be tested but should be checked regularly against a checklist.

To find out more about what needs testing and how regularly read our Sprayer Testing Card and Pellet Applicator Testing Card.  Remember that many farm assurance schemes and supermarket protocols may require testing more frequently than the intervals depicted here.
