With potato planting just around the corner, growers are being advised to check whether their NSTS certificate is still valid.
Under the Nematicide Stewardship Programme (NSP) and Red Tractor standards, granular applicators must be inspected and certified by a National Sprayer Testing Scheme (NSTS) engineer at least every two years.
However, many major processors and farm assurance schemes now require an annual test for peace of mind. A valid NSTS certificate isn’t just a “badge” for your audit; it’s proof that your machine is applying expensive product at the exact rate required—saving you money and protecting the environment,” says Techneat’s James English.
He advises growers not to wait until March, as engineering lead times can stretch quickly as the weather warms up.
He also reminds the NSP protocol requires that all applicators are fitted with an in-cab device allowing the operator to shut off the flow at least 3 metres before the end of the row. This ensures all granules are fully incorporated and none are left on the headland surface. “Now is the time to test your electronic clutches or shut-off motors. It’s much easier to fix a wiring fault in the workshop than in the middle of a 40-acre field,” he adds.
Stewardship isn’t just about compliance; it’s about keeping these vital tools available, he notes. “The industry is under constant scrutiny regarding the use of granular nematicides. By ensuring your Techneat equipment (or any applicator) is serviced, calibrated, and NSTS-tested, you are doing your part to protect the future of the UK potato industry.”
