In accordance with Article 6 of Regulation (EC) No 396/2005, the Agriculture and Horticulture Development Board (AHDB) submitted a request to the competent authority in the United Kingdom (evaluating Member State (EMS)) to modify the existing maximum residue level (MRL) for the active substance deltamethrin in kale. To accommodate for the intended use of deltamethrin, it was considered necessary to raise the existing MRL. Based on the evaluation report prepared by the EMS in accordance with Article 8 of Regulation (EC) No 396/2005, EFSA concludes that the applicant provided sufficient data to derive an MRL proposal of 0.15 mg/kg for the proposed uses in kale. Adequate analytical enforcement methods are available to control compliance with the proposed MRL for deltamethrin in kale. In a tentative risk assessment, no consumer concern has been identified; however, the risk assessment was affected by non-standard uncertainties. Further risk management considerations are required to decide whether the MRL proposal is acceptable.

The mortality of organisms exposed to toxicants has been attributed to either stochastic processes or individual tolerance (IT), leading to the stochastic death (SD) and IT models. While the IT model follows the principles of natural selection, the relevance of the SD model has been debated. To clarify why the idea of stochastic mortality has found its way into ecotoxicology, we investigated the mortality of (Linnaeus, 1758) beetles from pesticide-treated oilseed rape (OSR) fields and unsprayed meadows, subjected to repeated insecticide treatments.

Background: Selective insecticides and insecticide-resistant natural enemies are components of chemical and biological methods that can be compatible in an integrated pest management (IPM) program. Many insecticides that are labeled for treatment against insects in Brassica crops have lost their efficacy because of the development of resistance. However, natural enemies can provide an important role in regulating the population of these pests.

The consideration of ecological and human health risk is an emerging concern with the excessive or inappropriate use of deltamethrin. In this study, the degradation conditions of the newly deltamethrin-degrading strain Stenotrophomonas maltophilia XQ08 were optimized, which were temperature 35 °C, pH 7.5, cell concentration 5.

Research evidence suggests that pesticide residues are one of the leading potential causes of the decline in pollinators, especially during vulnerable periods such as foraging in the early springtime. In China, no research quantifies pesticide residues in the nectar and pollen of honey bee colonies during this period or examines the potential risks and toxicity of pesticides to honey bees. Oilseed rape is one of the first and primary bee-attractive plants in most parts of China.
