Hop represents one of the crops which need relatively intensive protection from pests and diseases. Consequently, it requires despite of the Good Agricultural Practice and Integrated Plant Protection Approach in comparison to other grown crops, a slightly higher number of sprayings and used Plant Protection Products (PPP), which has made the hop growing very undesirable among broader public for many years. This paper reports the results obtained from 2006 to 2008 of the investigation on the presence of PPP residues and heavy metals in hop gardens and groundwater in all Slovene regions where hop is grown. From the results it could be seen that there are only few residues of PPP in hop garden soils and no residues coming from hop growing in ground water. Nevertheless, we found quite high amounts of copper in the majority of investigated hop gardens, since copper has been the main fungicide in hop growing to control downy mildew for more than 30 years.
