Pesticides are an important pillar of food production today. The use of pesticides has increased in recent years as the world's population has grown and food production has increased. The large‐scale application of pesticides in nature leads to pesticides also reaching non‐target areas. Here, they can cause lasting damage to existing ecosystems and natural communities. One important pathway is the flushing of pesticide residues from agricultural fields into adjacent streams. It has been observed that the surface runoff leads to high concentrations of pesticides in surface waters and alters the community there. This raises the question on how exactly the input takes place and how risk mitigation measures such as vegetated buffer strips (VBS) can optimally retain pesticides in the field. These questions, among others, were the objectives of the "Kleingewässermonitoring" (KgM), in which small streams in agricultural environments were sampled on a large‐scale basis in 2018 and 2019 using rainfall‐related and grab samples
