AB  - BACKGROUND: Determining the environmental behavior and fate of chemical compounds 
      during technological processing of plants is a task of great significance 
      nowadays. However, the current knowledge is still incomplete for unique herbal 
      matrices belonging to minor crops. The research in this article presents, for the 
      first time, the dissipation kinetics and processing behavior of carboxamide 
      boscalid (BOS) and stobilurin pyraclostrobin (PYR) fungicides during glasshouse 
      dill (Anethum graveolens L.) cultivation. RESULTS: The half-lives (t(1/2) ) of 
      BOS and PYR after application at the recommended and double dosage were in the 
      range: 1.62-2.01 days in plant and 2.08-4.85 days in soil, respectively. The 
      processing behavior in dill was estimated after washing, hot air drying and 
      drying in sunlight without/with pretreatment. Processing factors (PFs) were above 
      1 after drying (PF = 1.24-1.39 hot air; PF = 1.15-1.28 sunlight) and below this 
      value when the washing step was applied (PF = 0.31-0.42 hot air; PF = 0.21-0.34 
      sunlight), indicating the highest effectiveness of reduction, up to 73% BOS and 
      79% PYR. CONCLUSION: BOS/PYR residues at pre-harvest intervals after both doses 
      were below European Union (EU) maximum residue limits (MRLs). The highest 
      effectiveness was noted for drying carried out with the washing step, which has a 
      great influence on the concentration of residues in the final product. The 
      findings can supplement PF databases not set for minor crops and can be used to 
      establish MRLs and determine human exposures more accurately in risk assessment 
      studies. (c) 2021 Society of Chemical Industry.
