    Abstract In the process of approval of active substances and authorization in the European Union and at the member state level, it must be shown by the applicant that an unacceptable risk for nontarget organisms in the aquatic environment by the active substance can be excluded. To achieve this aim, standardized models, scenarios, and agreed pesticide input parameters have to be used to calculate the exposure as defined by the FOrum for the Co-ordination of pesticide fate models and their Use (FOCUS). During a period of daily surface water sampling lasting 3.5 years, a survey was conducted among farmers in the highly vulnerable catchment of Grote Kemmelbeek in Belgium to collect agronomic data on crops, application dates, and application rates of 12 applied herbicides and one metabolite. Daily surface water concentrations for the same herbicides were measured over 2.5 years for a second, much larger but less vulnerable, catchment of Kleine Aa (KAa). A comparison of realistic worst-case predicted environmental concentrations in surface water (PEC

    Abstract BACKGROUND: Groundwater—especially for the use as drinking water—is a strictly protected resource in the existing guidelines for pesticide registration and drinking water protection in the EU. One aspect that has hardly played a role in this context so far is the attenuation of pesticide concentrations along the flow path from the regulatory leaching concentration at a depth of 1 m below the applied field to raw water abstraction systems. The soil metabolite N,N-dimethylsulfamide (DMS) is formed from two fungicidal substances: tolylfluanid and dichlofluanid. According to the EU guidance document on relevant metabolites in groundwater, DMS is a “non-relevant” metabolite. However, long-term application of the two active substances on permanent crops has resulted in elevated and quantifiable amounts of DMS in groundwater catchment areas of water supplying plants. Therefore, in the case of DMS, substantial monitoring data is available. This enables in combination with groundwater modeling, a quantitative analysis of the natural attenuation of DMS concentrations over time and distance. To this end, extensive real-world data from three case studies of drinking water catchment areas in Germany were analyzed. RESULTS: The environmental fate of DMS in soil and groundwater was evaluated according to the respective data determined at the study sites. Analyses using monitoring data and combined modeling approaches as well, were performed to obtain comparable results. These merged outcomes from monitoring and modeling show total attenuation factors of 12–93 from leachate at 1 m depth down to monitoring wells—close to raw water collection. If concentration attenuation further downwards to collected raw water is considered, the overall attenuation factor is even higher (40–246). CONCLUSIONS: The conditions at the catchment areas of the three case studies are very diverse, thus providing a wide range of attenuating conditions. When following the path of DMS from its formation in soil below a treated field, to its leaching into the aquifer, and within the aquifer down to the raw water collection site, its concentration in water is continuously and consistently decreasing. The results from DMS represent conservative estimations due to non-sorptive, quick transport processes. Extended to other sorptive solutes, it represents the lower end of expected attenuation. Therefore, natural pesticide concentration attenuation processes are suggested for the consideration in regulatory pesticide risk assessments for a more realistic yet still protective evaluation of expected concentrations in raw water.

    Abstract A growing and promising sector of precision agriculture is the site-specific application of pesticides, having a high potential for reductions in pesticide use. Within the research project ‘AssSys’, site-specific pesticide applications with a direct injection sprayer system and an automatic application assistant were evaluated economically with respect to herbicide and fungicide applications. The application assistant aims to support farmers in decision-making and implementation of site-specific pesticide applications either in the planning stage or as ex-post analysis. The economic assessment was based on field trials and scenario analysis referring to a model farm. The field trials were conducted in 2018 and 2019 in northern Germany. In the scenario analysis, two site-specific application scenarios were compared to conventional uniform treatment (100% of the field area). Weed monitoring was conducted as (1) standard procedure according to integrated pest management, (2) camera-based and (3) drone-based in the field trials. The pesticide application costs include pesticide costs, labour and machine costs of monitoring and pesticide applications. Investment costs of the necessary technical equipment for site-specific applications were included as annual labour and machine costs. As a major key performance indicator of partial budgeting at field level, extended gross margins were calculated. The economic scenario analysis showed pesticide application cost savings from 26 to 66% for site-specific applications compared to conventional applications. The average extended gross margin for site-specific applications of 787 € ha⁻¹ compared to 631 € ha⁻¹ for conventional application showed a clear economic advantage of the site-specific application scenarios. Site-specific pesticide applications can support farmers in implementing precise, sustainable and economically beneficial pesticide management. The technology presented may contribute to meet the goals of the European Green Deal to reduce use and risks of pesticides.

    Abstract Die teilflächenspezifische Applikation von Pflanzenschutzmitteln ermöglicht die variable Anpassung der Fungizidmenge an das räumliche Auftreten von Pflanzenkrankheiten im Schlag. Hierfür müssen jedoch geeignete Methoden zur Krankheitserkennung oder –prognose vorhanden sein. Deshalb wurde im Rahmen des Forschungsprojektes „AssSys“ (Anonym, 2021) ein teilflächenspezifisches Prognosemodell entwickelt, welches die relative räumliche Verteilung von Fusarium-Halmbasisverbräunung in Winterweizen prognostiziert. Hierbei werden anhand von topographischen Daten (Höhendaten, SAGA Wetness Index) drei Zonen unterschiedlicher Befallsgefährdung ausgewiesen. Zur Entwicklung und Evaluierung des teilflächenspezifischen Prognosemodells wurde in den Jahren 2011–2012 sowie 2018–2020 das räumliche Auftreten von Fusarium-Halmbasisverbräunung auf mehreren Untersuchungsflächen je Jahr bonitiert. Die Modellgüte wurde anhand der Koinzidenz zwischen bonitiertem und prognostiziertem Befalls­niveau über die Untersuchungsflächen bestimmt. Diese variiert abhängig von der Datenquelle und der ausgewiesenen Zone zwischen 57 % und 80 %. Das teilflächenspezifische Prognosemodell ermöglicht somit die Identifi­zierung besonders sowie wenig vulnerabler Bereiche in Schlägen und wird prototypisch als Webservice via www.isip.de realisiert.Gemäß dem Entwurf des Gesetzes zur Änderung des E-Government-Gesetzes (EGovG) und zur Einführung des Gesetzes für die Nutzung von Daten des öffentlichen Sektors (DNG) erfolgen die technischen Erläuterungen der REST-konformen Programmierschnittstellen nach dem OpenAPI Standard.

    Site-specific application of pesticides allows to adapt the application rate to the spatial distribution of plant disease(s) in fields. For this purpose, suitable procedures for disease detection or prognosis are necessary. Therefore, a site-specific prognosis model was developed in the research project “AssSys” (Anonym, 2021) to predict the relative spatial distribution of Fusarium crown rot in winter wheat. Based on topographic data (elevation ...
