Evaluation of confirmatory data following the Article 12 MRL review for terbuthylazine

The applicant Syngenta Crop Protection AG submitted a request to the competent national authority in Spain to evaluate the confirmatory data that were identified for the active substance terbuthylazine in the framework of the maximum residue level (MRL) review under Article 12 of Regulation (EC) No 396/2005 as not available. Based on the information provided by the applicant and assessed by Spain, EFSA concludes that the tentative MRL is confirmed in sweet corn and sunflower seeds, but not in lupins/lupini beans and cotton seeds. Regarding livestock metabolism study, EFSA acknowledges that a new goat metabolism study was submitted. However, due to the shortcomings identified, the metabolism in ruminants cannot be fully depicted. Despite these deficiencies, it can be concluded that at the calculated maximum dietary burdens significant transfer of residues in bovine tissues and milk is not expected and therefore the tentative MRLs can be confirmed. The consumer risk assessment performed in the framework of the MRL review was updated using revision 3.1. of the PRIMo, considering the actual MRL values implemented in Regulation (EU) 2021/1795 and excluding the crops on which the uses are not supported by Article 12 confirmatory data (cotton seed and lupins/lupini beans). No consumer intake concerns were identified.
