Visser Horti Systems now SKL certified

The use of plant protection products through watering and spraying equipment must be carried out efficiently and above all safely. Visser Horti Systems is approved by SKL to perform the mandatory inspections of watering and spraying booms used in the Dutch horticultural sector.

About SKL testing

A SKL test is a recurring inspection of spraying equipment on functionality and safety. The SKL protocol for inspections is based on the content of the article 8 of the EU directive for a Sustainable Use of Pesticides. In 2015, the ministry of Economic Affairs has integrated the obligation to inspect sprayers in their legislation. Meaning that legally all field crop sprayers have to be inspected every 3 years by an official SKL certified testing station.
