Beobachtungen aus Freilanduntersuchungen und Ergebnisse aus Regressionsanalysen zum Einfluss von Witterungsfaktoren werden dargestellt. Verschiedene Untersuchungen zu Materialeigenschaften, die Einfluss auf die Auswaschbarkeit von Bioziden haben können, werden für zwei Farben verglichen. Ein Modellansatz zur Beschreibung von Laborversuchsdaten wird kurz erläutert.

Laboratory and field tests indicate similar relations of results on carbendazim, diuron, terbutryn and OIT from different coatings in laboratory and field experiments. Emissions were higher in EN 16105 laboratory tests than from vertically installed test specimens exposed to weathering, and slower for microencapsulated biocides. Competing processes that cause losses of active substances can occur in both tests, but to a higher degree in field experiments. Emission curves related to runoff water were similar in repeated field experiments. Relative humidity, temperature and global radiation were identified as meteorological factors that affect leaching by complex interaction besides the amount of driving rain.
