KWS | Einbeck

Written by Anne Hofmann and Luca Weber

Together with 17 fellow Early Career Researchers from CEPLAS, we traveled from Düsseldorf and Cologne to Einbeck to take part at the TalentCampus@KWS 2026. We arrived in Einbeck the day before and explored the city centre during an interesting guided historical tour titled “Through the Centuries”. During the follow-up joint dinner at the traditional “Brodhaus”, one of the oldest pubs in Lower Saxony, we got to know each other better and tested some of the famous Einbecker beer.

The following morning began with a field trip focused on winter wheat breeding, hosted by Alex Windhorst, Assistant Breeder at KWS. We learned about double haploid wheat breeding and climate adaptation strategies in modern breeding programs. Also, Alex highlighted the laborious process of variety registration and publication through the Federal Plant Variety Office (Bundessortenamt).

After the field trip, each of us followed an individual program of tours and talks tailored to their own interests. 

Luca:

I continued my day by exploring the new product-oriented pea breeding strategy at KWS. Karen Ilsemann introduced us to product-driven breeding approaches for peas with future applications such as plant-based burgers and vegetable milk alternatives. I even had the chance to try pea-based milk in smoothies that were offered in an exhibition hall next door, which made the topic feel very tangible and close to everyday life. Another highlight for me was the greenhouse tour led by Isabel Blumenberg. I was especially intrigued by the automated PhenoFactory phenotyping system and the machinery used in state-of-the-art breeding research. Further, my day also included two talk sessions. The first, “Career Talks – Personal Growth” (pun intended), focused on career development and personal perspectives within KWS. The second session emphasized the importance of data science as the backbone for making reliable decisions quickly and for supporting breeders in modern research and breeding programs.

To conclude my visit, I explored the large-scale machinery used for plot trial assessments and phenotyping, including specially modified tractors designed for highly specific breeding and research purposes. It was impressive to see the level of engineering and customization involved in collecting precise field data and enabling data-driven decision-making. What stood out to me most throughout the excursion was the dedication of the KWS employees and their commitment to developing innovative strategies for a productive future in agriculture.

Exploring sustainable “Pest Control” at Bayer

Written by the CEPLAS Early Career Researchers Abdulkabir O. Abdulmalik and Nhu L.T. Tran

Our recent guided tour at Bayer provided a fascinating insight into the cutting-edge developments in pest control, led by Jürgen Benting (LifeHub Monheim). The tour featured an in-depth exploration of Bayer's commitment to sustainable practices and environmental responsibility.

Insecticide Development:

Bayer is at the forefront of developing insecticides that are not only highly specific but also environmentally conscious, avoiding harm to beneficial organisms such as honeybees. The journey of insecticide development involves a rigorous process of screening thousands of molecules through in vitro and in vivo assays.

The selection process narrows down the candidates, leading to extensive testing on plants. Parameters such as efficacy, absorption by plants, effectiveness, and residuals are meticulously evaluated. Before field tests, plants are subjected to simulated weather conditions, including rain, high temperatures, and humidity, to gauge the compounds' activity in various climates.

Field Testing:

The final phase of testing takes place in the field, spanning different locations both within and outside Europe. This comprehensive approach ensures that the developed insecticides are effective and adaptable to diverse environmental conditions.

Greenhouse Innovations:

Bayer's commitment to safety extends to its testing facilities. The guided tour also included a visit to a state-of-the-art greenhouse equipped with automatic spraying devices. These devices not only facilitate seamless lab-to-field transfer for testing but also play a crucial role in protecting the well-being of workers.

Talk Session

Ensuring safety of modern crop protection - insights from Maxie Kohler’s talk on metabolism studies

The talk aimed to shed light on Bayer's commitment to developing sustainable and safe pesticides, emphasising the importance of assessing residuals that make their way from plants and soil to livestock and eventually into the human body.

Maxie Kohler explained that while everything has a hazard potential, the actual risk is contingent upon exposure. The risk evaluation process involves analysing various parameters, starting with the identity and concentration of metabolites in food.

One key aspect of the talk was the integration of data of human food consumption. By incorporating these, Bayer ensures that the hazard potential is contextualised with the exposure in the broader scope of people's dietary habits. This approach allows for a more nuanced understanding of risk, considering not just the inherent hazard but also the practical exposure levels in everyday life.

Maxie Kohler emphasised Bayer's commitment to transparency and accountability in the risk evaluation process.

Modelling of insect development times using Dynamic Energy Budget (DEB) model - Christian Baden

This talk highlighted Bayer's approach to predicting development times in laboratory cultures of insects as a step towards effective pest control.

Modelling insect development trajectory requires critical considerations on the temperature dependence of growth behaviours and model variability in development times.  Christian Baden’s talk focussed on the dynamic energy budget (DEB) approach that is being used to simulate organism performance in terms of growth and reproduction. In Bayer's commitment to enhancing food quality, the DEB approach proves valuable for analysing conditions in insect rearing, enabling informed decisions on optimal temperature regimes, and establishing ad libitum food levels. This was another session that showcased the incredible work that underlies the production of effective pest control products and management strategies.

Quantitative biology from the perspective of a data scientist - Dr Benjamin Buer

While exploring the “behind the scenes” of pest control product development, Benjamin shared interesting views on how data scientists help in the process of new target discovery and validation.

Benjamin Buer explained that target identification is one of the most critical steps in chemical genetics and drug discovery. Interestingly, Bayer adopts two complementary screening approaches to identify starting points for novel products: biological in vivo screening and target-based in vitro/in silico screening. Data scientists work at the intersection of these approaches. They work with the results of bioscreening to understand what the mode of action of a bioactive molecule and use in silico systems to facilitate target-based screenings. In this approach, knowledge graphs and systems biology are utilised for target discovery and target assessment.

Technological advancements in transcriptomics have helped in making the process of target discovery easier. Benjamin Buer explained how biological data has significantly contributed to cell type identification, cell hierarchy reconstruction, inference of regulatory networks, transcriptional bursting, and stochastic gene expression. These advancements have, in turn, facilitated the validation processes for target genes. Bayer’s team of data scientists continuously work to build computational tools to aid these processes. In the end, Benjamin Buer concluded, that integration of knowledge and insights generated by such tools is essential for target identification and validation.

The future of Innovation Agriculture: Eike Heilmann’s talk on small molecules research in the CropKey Era

Under the motto "produce more, restore more," Eike Heilmann shared insights into the team's journey, spanning from the design of novel molecules to the development of production lines aimed at minimising the carbon footprint. Products developed with this novel approach are called “CropKey”.

The core ethos of the "Innovation Agriculture" team reflects a commitment to not only increasing agricultural productivity but also contributing to ecological restoration. Eike Heilmann highlighted the dedication to creating new molecules from scratch, initiating a comprehensive process that encompasses screening and the establishment of production lines designed with sustainability at the forefront. Eike Heilmann also provided valuable insight into the time-intensive nature of small molecules research, emphasising that it typically takes 12-14 years "from first discovery to market."

The talk illuminated the forward-thinking approach of Bayer's "Innovation Agriculture" team with the CropKey concept. By prioritising the development of molecules with a novel and by-design-safe mode of action as well as sustainable production processes, the team exemplifies Bayer's commitment to shaping the future of agriculture responsibly. The 12 -14 years journey from structure to market highlights the dedication and patience required to bring about meaningful and impactful innovations in the field of crop protection and agricultural sustainability.

Conclusion

Bayer's dedication to sustainable and responsible pest control practices was evident throughout the guided tour. The company's holistic approach, from meticulous laboratory testing to extensive field trials, reflects its commitment to providing effective solutions while prioritising environmental and worker safety.

This report serves as an acknowledgement to Bayer's ongoing efforts to address pest control challenges responsibly and underscores its position as a leader in developing innovative, sustainable solutions for a greener future.
