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.
