The NSTS test is a requirement of the major UK crop assurance schemes and of supermarket protocols.

The NSTS test will become a requirement for all boom sprayers by 2016 under the requirements of the Sustainable Use Directive and be retested every five years until 2020 when the requirement for re-testing reduces to every three years.  The SUD is mandatory throughout the EU.

Furthermore, a NSTS certificate will indicate to clients your adherence to best practice procedures and reflect favourably upon your professionalism.
