Abstract

Unsatisfactory technical condition or insufficient adjusting of plant protection machines may cause considerable environmental pollution. During their maintenance and cleaning (mechanical errors) more or less concentrated plant protecting chemicals may get into living water and from these even into drink water. Naturally, during spraying the wind may drift the chemicals into natural waters. In 1999 the International Standardization Organization has established a working group to elaborate rules to decrease environment pollution by efficient cleaning of sprayers. As a result of their work, in March 2004 the ISO/DIS 22368 standard draft came into force, which describes in three chapters the inner cleaning of sprayers as well as the investigation of effectiveness of cleaning devices for outer and inner side of pesticide tank of sprayers. Our aim was to investigate the effectiveness of the cleaning devices, the contamination quantity and relation of chemicals on the sprayers and make proposals to improve directions of the standard. Keywords: plant protection, maintenance and cleaning, international standards, measuring methods.
