Application

The analytical standard can be used for the following: To determine the toxicity of pyridalyl on each growth stage of 2 insect pest species and to evaluate its cytotoxicity on the Sf9 insect and CHO-K1 mammalian cell line using the trypan blue exclusion method To assess the lethal and sublethal effects of methoxyfenozide and pyridalyl on the larval ectoparasitoid Habrobracon hebetor Investigation of the molecular action of Pyridalyl via cytochrome P450 activity using non-selective cytochrome P450 inhibitor, 1-ABT (1-aminobenzotriazole) Evaluation of in vitro insecticidal activity of pyridalyl nanosuspension in comparison to technical material and commercial product against tomato fruit and shoot borer (Helicoverpa armigera) To elucidate the persistence behavior and risk assessment of pyridalyl in tomato, cabbage, and cultivated field soil over two consecutive seasons

General description

Pyridalyl belongs to a new class of insecticides that has no cross-resistance with any other class of insecticides. Pyridalyl acts by contact and ingestion and is effective in controlling lepidopteran and thysanopteran pests in cotton, fruits, and vegetables such as cucurbits and lettuce.Pyridalyl 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.Pyridalyl was approved on 1 July 2014 under the Commission Regulation (EU) No 143/2014/EU as per the Regulation (EC) No 1107/2009 as amended by Commission Implementing Regulations (EU) No 540/2011 and 541/2011. Upon receiving an application to set the new MRLs for pyridalyl from the Evaluating Member State (EMS) following Article 9 of the Regulation on 14 January 2009, EFSA has proposed an MRL of 1 mg/kg for tomatoes, 1 mg/kg for aubergines (eggplants), 2 mg/kg for peppers, 0.2 mg/kg for cucurbits (inedible peel), 3 mg/kg for lettuce, and 0.1 mg/kg for cottonseed.
