V posledních letech se strobiluriny staly velmi významnou skupinou účinných látek používaných proti chorobám ječmene i chmele. Jsou to látky se širokým fungicidním účinkem. Vyznačují se velmi variabilními vlastnostmi, včetně spektra jejich účinnosti. Působí především preventivně, mají však i kurativní a některé i eradikativní účinnost. Všechny působí kontaktně, některé také hloubkově nebo systemicky.Vzhledem k nárůstu rozsahu použití strobilurinů v ochraně ječmene a chmele bylo nezbytné zavést sledování jejich reziduí v surovině, meziproduktech i finálním produktu.Mikulíková, R. -Svoboda, Z. -Běláková, S.: Monitoring of residues of fungicides used in malting barley protection. Kvasny Prum. 54, 2008, č. 11-12, s. 332-337. During the last years strobilurines have become a very important group of efficacious substances used against the diseases of barley and hop. These are substances with a wide fungicide effect. Their characters, including the efficacy spectrum, are very variable. They affect mainly preventively, but also curatively and they even have eradicative effects. All of them act in contact, some of them also in depth or systemically.Considering the increase in the extent of strobilurine use in the protection of barley and hop, it was necessary to introduce monitoring of their residues in raw materials, intermediaries and a final product.

“…The obtained dry residue was dissolved with 5 ml of acetonitrile in the ultrasound bath for 1 minute. The mixture was purified through the SPE column [2]. Three types of SPE columns were tested for purification -ENVI TM CarbII/PSA, LiChrolut EN and Discovery DSC-18.…”

“…GC with an electron capture detector (GC-ECD) (Balinova et al, 2007;Sharma and Singh, 2012) or coupled to mass spectrometry (GC-MS, GC-MS/MS) (Esteve-Turrillas et al, 2005;Kolberg et al, 2011) has been the most popular method. Some studies carried out on LC (LC-MS or LC-MS/MS) were also reported in the past few years (Baskaran et al, 1999;Martínez et al, 2006;Chen and Chen, 2007;Bletsou et al, 2013).…”

“…Several multiresidue methods for the determination of pesticide residues in fruits are mainly based on solvent extraction by organic solvents such as acetone, petroleum ether and dichloromethane, solid-phase extraction (SPE) using sorbents such as Florisil, silica gel, C 18 and amino, supercritical fluid extraction (SFE) (Balinova et al, 2007;Lehotay and Ibrahim, 1995), solid-phase microextraction (SPME) using a PA (polyacrylate) fiber phase (Menezes Filho et al, 2010) and Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) (Lehotay et al, 2010). Over the last years, liquid-liquid microextraction (LPME) in this different application modes (singles drop microextraction, dispersive liquid-liquid microextraction and hollow fiber-LPME) has been increasingly applied for the extraction of both inorganic and organic analytes from different matrices, including toxic chemicals like pesticides (Asensio-Ramos et al, 2011;Huo et al, 2011).…”
