Rapid screening of stobilurins in crude solid materials (wheat grains) using DART-TOFMS

Direct control of solid materials for pesticide residues is a challenging task enabling fast contamination screening. In our study, we investigated direct analysis of strobilurin fungicides in milled wheat grains. Strobilurins, systemic pesticides originated from natural fungicidal derivatives, play an important role in control of various plant pathogens. Because of their unique protective properties, significant yield enhancements and longer retention of green leaf tissue, strobilurins have been widely used in agriculture since their introduction on the market in 1992. As other pesticides, these compounds are involved in control and monitoring surveys undertaken by regulation authorities.

AccuTOF-DART system was used for examination of milled wheat grains containing incurred residues of azoxystrobin, kresoxim methyl and pyraclostrobin.
