摘要

农药对于应对养活迅速增长的世界人口的挑战至关重要。然而,至关重要的是,它们的使用方式不会危及人类或环境的安全。非饮食工人的风险评估考虑了可从植物叶片转移到皮肤或衣服上的残留物的数量,称为可去除的叶面残留物(DFRs)。由于DFR研究的成本和季节性特征,DFR数据的稀缺性是DFR数据外推到不同作物/叶片的障碍。本文以杀菌剂二苯醚康唑EC 10%为例,验证了一种新的概念验证技术,以研究可能影响DFR(叶片质地)的因素,并对各种叶片(即法国豆、大豆、番茄、油菜和小麦)进行了研究。DFR以油菜最低(31.0±3.4%),豆荚最高(82.0±2.9%)。本研究结果中DFR的显著差异揭示了叶表面作为影响DFR的主要因素的重要性,并支持了实验室方法在更广泛数据生成中的应用。更多的数据生成将使外推节省资金和资源。

A new laboratory method to study the impact of leaf texture on pesticide dislodgeable foliar residues (DFR).

Pesticides are vital in meeting the challenge of feeding the rapidly increasing world population. However, it is crucial that they are used in a way that does not compromise the safety of humans or the environment. Non-dietary worker risk assessments consider the amount of residue which can be transferred from plant foliage to the skin or clothes, known as dislodgeable foliar residues (DFRs). DFR data scarcity due to the costly and seasonal characteristics of DFR studies is an obstacle to the extrapolation of DFR data to different crops/leaves. This paper validates a new proof-of-concept technique to investigate factors that may affect DFR (leaf texture) using the fungicide difenoconazole EC 10% as an example on various leaves (i.e., French bean, soybean, tomato, oilseed rape, and wheat). DFR was the lowest in the case of oilseed rape (31.0 ± 3.4%) and the highest in French beans (82.0 ± 2.9%). This significant difference in DFR in the findings of this study sheds light on the importance of the leaf surface as a major factor affecting DFR and supports the application of the laboratory method for more extensive data generation. More data generation would enable the extrapolation saving money and resources.
