Nickisch, Krömer (2015) A standardised approach to identify worst-case FOCUS surface water exposure profiles in aquatic pulsed exposure events

The outcome of Tier 1 risk assessment for plant protection products frequently calls for the use of higher tier approaches to evidence an acceptable risk to aquatic organisms. In this context, laboratory pulsed exposure experiments can be used to test the effects of varying exposure concentrations on the mortality and/or immobilization of organisms.

Nickisch, Erlacher (2014) Modelling concentrations of PPP in ground water after spray application to hop

Hop is not available as crop in the FOCUS groundwater models. In this study we tested if it is necessary to consider the singularity of a crop for the registration of a pesticide or if it is possible to use one of the existent FOCUS crops as a surrogate. Calculations were performed for the non-FOCUS crop hop using hop specific data (e.g. LAI) derived from field measurements.

Murfitt et al. (2012) Bird focal species for pesticide risk assessment in orchards in Spain

This poster summarises the findings of Syngenta studies to identify focal species in four orchard crops in Spain. The aim is to show focal species for pesticide risk assessments in these crops and also to demonstrate the main principles involved in focal species selection.

Gerlach, Schabacker, Ludwigs (2012) Granivorous birds - Exposure reduction by de-husking behaviour

Granivorous birds of the families Passeridae (sparrows), Fringillidae (finches) and Emberizidae (buntings) are known to de-husk seeds prior to consumption. De-husking is an inhered behavioral trait of these species groups. A specialised beak structure allows the birds to crack seeds and discard the husk (i.e. de-husking) before swallowing the kernel – this was described in detail already by Ziswiler (1965).

Henn, Erlacher (2012) Highest tier? EPAT analysis in aquatic risk assessment of plant protection products

For standard risk assessment conducted during the EU review of plant protection products (PPP), the concentration of active substances in water bodies adjacent to a single field is calculated using the surface water model FOCUS SWASH.

Schabacker et al. (2012) Focal Bird Species for Amenity Grassland Risk Assessments

EFSA guidance (EFSA Journal 2009; 7/12) gives a list of crop groups and indicator species for the risk assessment of birds and mammals. For agricultural grasslands such as pastures and meadows, the default focal species given by EFSA are the house sparrow, linnet, pink-footed goose, and yellow wagtail.

Henkes, Henkes (2012) Computer controlled High Gradient Extractor for soil organisms

Soil micro-arthropods, such as Acari and Collembola, are essential components of the soil decomposer system and valuable indicators of soil quality and soil biodiversity. Evaluating the impact of agrochemicals or assessing the risks posed by genetically modified plants (GMOs) on micro-soil organisms is likely to gain more importance in the future.

Körner et al. (2012) Relevant Lizard Species for the Risk Assessment of Plant Protection Products in Northern and Central Europe

According to the new data requirements under the EU regulation 1107/2009, reptiles come into question regarding risk assessments of plant protection products (PPP). Although no specific data requirements on reptiles are stipulated in the respective EU documents (e.g. SANCO 11802/2010/rev July 2010) some toxicity data are available in the open literature. These data are intended to be used in the risk assessment.

Lutzmann et al. (2012) Relevant Lizard Species for the Risk Assessment of Plant Protection Products in Southern Europe

According to the new data requirements under the EU regulation 1107/2009, reptiles come into question regarding risk assessments of plant protection products. Although no specific data requirements on reptiles are stipulated in the respective EU documents some toxicity data are available in the open literature.

Lutzmann, Vogel, Böhme (2012) Are the Mediterranean chameleon species possible focal species for risk assessments for PPPs in Southern Europe?

According to the new data requirements under the EU regulation 1107/2009, reptiles come into question regarding risk assessments of plant protection products (PPP). Although no specific data requirements on reptiles are stipulated in the respective EU documents some toxicity data are available in the open literature. These data are intended to be used in the risk assessment.

Seiterle-Winn, Hörold (2012) Impact of the Rainfall Criterion in the EFSA Soil Persistence Guideline on Kinetic Evaluation of Field Degradation Trials

In 2010 the EFSA published a new guidance on soil persistence for the derivation of field half lives of pesticides with the aim to exclude loss processes at the soil surface (i.e. photolysis, volatilisation) .
