Tebufenpyrad is a non-systemic pyrazolecarboxamide acaricide that gets activated both by contact and ingestion. It targets the NADH-ubiquinone oxidoreductase (complex I) site and acts as a mitochondrial electron transport inhibitor (MET I). Tebufenpyrad is used for the protection of all stages of Tetranychus, Panonychus, Oligonychus, and Eotetranychus spp. in top fruit, vines, citrus, vegetables, hops, ornamentals, melons, and cotton.
According to the Commission Implementing Regulation (EU) No 2009/11/EC of 18th February 2009, tebufenpyrad is not approved for use in the European Union (EU) as a plant protection agent, following the Regulation (EC) No. 1107/2009. But maximum residue levels of 0.01 mg/kg to 1.5 mg/kg are allowed for the presence of tebufenpyrad in products of plant and animal origin, according to the EU Reg. No 2017/693.
Tebufenpyrad has to be monitored in the Multiannual Control Programme for Pesticides Residues (MACP), run within the EU and EFTA in/on products of plant origin.

The certified reference material (CRM) is intended to be used as a calibrant for chromatography and other analytical techniques.
Profenofos CRM may also be used as given below:

• Evaluation of 250 pesticide residues extracted by QuEChERS method from 103 processed fruit samples using ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS)
• Gas chromatography-tandem mass spectrometry (GC-MS/MS) based analysis of 213 pesticide residues in soybean, after their extraction by QuEChERS procedure
• Detection of 252 pesticides extracted from surface water samples by solid-phase extraction (SPE) using liquid chromatography quadrupole-orbitrap high-resolution tandem mass spectrometry
• Multi-residue analysis of 160 multiclass pesticides using ethyl acetate (EtAC)/n. hexane mixture for extraction from chamomile, thyme, and marjoram samples and their analysis by gas chromatography-tandem mass spectrometry (GC-MS/MS)
• Simultaneous determination of 34 pesticides in various environmental water samples by dispersive liquid-liquid microextraction (DLLME) technique in combination with gas chromatography-mass spectrometry(GC-MS/MS)
• Quantitation of 40 multi-class insecticides and fungicides in 81 apple samples by using gas- and liquid- chromatography-mass, following a QuEChERS-based extraction
