We present neonicotinoid concentrations in guttation drops of commonly used maize () cultivars, germinated from seeds coated with active substances (a.s.): i) imidacloprid (IMD), ii) clothianidin (CTN) and iii) thiamethoxam (THM) over two growing seasons. In one variant clothianidin was applied as seed granule. The trial took place at the experimental fields of the Julius Kühn-Institut in Berlin in 2010 and 2011. Data from 2010 are related to a presentation of "Pesticides in guttation droplets following seed treatment - field studies" (Schenke et al., 2011) [1] presented at the SETAC North America conference and only some figures were used in the "Scientific opinion on the science behind the development of a risk assessement of plant protection products on bees (, spp. and solitary bees)" (EFSA, 2012) [2]. Only parts of the data from 2011 was presented in relation to the "Exposure of Coccinellidae to guttation droplets on maize seedlings with seed or granule treatment of neonicotinoids" (Schenke and Heimbach, 2014) [3]. The article describes the study sites, the variants of treated maize seeds, sample collection and the analytical methods used to quantify the neonicotinoids and relevant metabolites of IMD (5-OH-IMD and IMD-olefine) and of THM (CTN) in guttation drop samples. The complete field data set is publicly available at the OpenAgrar repository under https://doi.org/10.5073/20180907-142020 (Schenke et al., 2018) [4].
我们展示了常用玉米（）品种的吐水液滴中的新烟碱类农药浓度，这些品种由包衣种子发芽而来，包衣中的活性成分包括：i）吡虫啉（IMD）、ii）噻虫胺（CTN）和iii）噻虫嗪（THM），研究跨越两个生长季节。在一个变体中，噻虫胺以种子颗粒的形式施用。该试验于2010年和2011年在柏林的尤利乌斯·库恩研究所的试验田进行。2010年的数据与在SETAC北美会议上发表的“种子处理后吐水液滴中的农药——田间研究”（申克等人，2011年）[1]相关，“关于植物保护产品对蜜蜂（、 spp.和独居蜂）风险评估背后科学的科学意见”（欧洲食品安全局，2012年）[2]中仅使用了部分数据。2011年的数据仅部分呈现于“新烟碱类种子或颗粒处理的玉米幼苗上瓢虫对吐水液滴的暴露”（申克和海姆巴赫，2014年）[3]。本文描述了研究地点、处理过的玉米种子变体、样本采集以及用于定量吐水液滴样本中新烟碱类农药以及IMD（5 - OH - IMD和IMD - 烯烃）和THM（CTN）相关代谢物的分析方法。完整的田间数据集可在OpenAgrar存储库中公开获取，网址为https://doi.org/10.5073/20180907 - 142020（申克等人，2018年）[4]。
