“…Practical tests have shown, that this may have an impact on the time needed until a PPP is taking effect. But, there was no difference concerning the efficacy of the PPP treatment during the field tests (Pohl et al, 2017).…”

The technical development of field crop sprayers have reached a high level. Due to automation and assistance modern sprayers are able to achieve very high application quality combined with low risks for environment and operator as well as high efficacy. But, the requirement to spray plant protection products as homogeneously as possible all over the field runs out of date. Due to possibilities arising from precision farming and digitalization of agriculture the idea of site specific application moves closer to realisation. Therefore two technologies are necessary, direct injection and sensor systems for weed, pest and disease detection. Moreover, the efficacy and safety of plant protection can be still raised by looking on the whole process of plant protection, meaning to integrate planning, preparation and documentation besides the application itself. The article gives an overview about the state of the art of field crop sprayers and their technical development.

“…Recently, the assistance system 'pesticide application manager' (PAM) has been developed which is able to automatically consider legal distance requirements to water bodies and landscape structures during pesticide applications via section control (Federle et al, 2014;Rajmis et al, 2016). The most recent developments in precision plant protection are site-specific applications with direct injection field sprayers (Pohl et al, 2017).…”

Economic potential of site-specific pesticide application scenarios with direct injection and automatic application assistant in northern Germany

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.
