Teflubenzuron is a type of benzoylurea insecticide that disrupts the chitin deposition in the insect cuticle by inhibiting chitin synthesis and molting. It is a systemic insect growth regulator used for the control of lepidoptera, coleoptera, diptera, aleyrodidae, hymenoptera, psyllidae, and hemiptera larvae in vines, pome fruit, stone fruit, citrus, cabbages, potatoes, vegetables, soybeans, trees, sorghum, tobacco, and cotton. It is also used to control fly and mosquito larvae and immature stages of locusts.
Teflubenzuron was included to the Annex I of Directive 91/414/EEC on 01 December 2009. Teflubenzuron is not approved for use in the European Union (EU). But the Annexe IIIA of Regulation (EC) No 396/2005 establishes the maximum residue levels (MRLs) of teflubenzuron in the range of 0.01–5 mg/kg in fruits, vegetables, crops, and livestock. Teflubenzuron is monitored in the Multiannual Control Programmes for Pesticides Residues (MACP), run within the EU and EFTA in/on products of plant origin.

Application

It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques.
The teflubenzuron certified reference material (CRM) may also find use as given below:

• Determination of 9 benzoylurea insecticides in fruit, vegetable, cereal, and animal product samples by pressurized liquid extraction and LC-MS/MS
• Simultaneous analysis of lufenuron, bifenthrin, and teflubenzuron residues in coconut water by matrix solid-phase dispersion extraction combined with reversed-phase high-performance liquid chromatography
• Development of a high performance liquid chromatography–triple quadrupole mass spectrometry (HPLC-MS/MS) based method for the simultaneous estimation of 7 benzoylurea insecticides in infused oolong tea
• Multi-residue analysis of pesticides in Açai fruit by an extraction based on matrix solid phase dispersion and determination using liquid chromatography
• Comparative study for the extraction of 9 benzoylurea insecticides using two dispersive liquid-liquid microextraction (DLLME) approaches from wastewater samples followed by their determination using liquid chromatography-quadrupole-linear ion trap-mass spectrometry
