Abstract. A granular applicator is a device that applies pesticides in a solid form. This may be either a dry granule, micro granule or pellet. The device consists of a hopper, metering and distribution system which spreads the granules in a band or broadcast manner. A granular spreader may be configured differently depending upon the distribution system and on the size and quantity of hoppers as well as the number of outlets and the drive type. The hopper size is normally between 30 l and 150 l. The working width can be as much as 24 metres. The spreader may be positioned in either the front or rear of a vehicle or several may be positioned on an implement. In Europe all machines used for the application of pesticides must be inspected because of the European Union Sustainable Use Directive (2009/128/EC). Proposals to include test methods in European standards are under study. Practical experience with band applicators and full width applicators has been developed, and respective requirements of the inspected machine, as used in the United Kingdom along with test equipment required, are deliverables to be shared. 2000 tests per year are carried out in the United Kingdom. It is envisaged that an ISO standard could evolve from the findings. This could be included in the EN ISO 16122 suite of standards.
