Lettuce is Colombia's most widely cultivated leafy vegetable, but in the absence of good agricultural practices, there is the risk of some pesticide residues that affect its safety and quality. This work aimed to identify the pesticides used by farmers for the lettuce crop, the iceberg variety ( var. capitata), in some municipalities of Cundinamarca (Colombia) and to investigate their residues by sampling and analysis. The farmers reported in the survey 44 active ingredients, most fungicides (54%), while the laboratory analysis showed 23 chemical compounds (52% insecticides, 39% fungicides and 9% herbicides). In addition, dithiocarbamates, procymidone and some organophosphates were among the active ingredients that exceeded the maximum residue limits (MRLs). About 80% of the identified pesticides were not registered with the regulatory entity Instituto Colombiano Agropecuario (ICA) for their use in lettuce, but some were in commercial products legally registered in Latin American and Caribbean countries.
生菜是哥伦比亚种植最广泛的叶菜类蔬菜，但由于缺乏良好的农业实践，存在一些农药残留的风险，这会影响其安全性和质量。本工作旨在确定在哥伦比亚昆迪纳马卡省（Cundinamarca）的一些城市中农民用于生菜（var. capitata）作物的农药，并通过抽样和分析来调查其残留情况。调查中，农民报告了 44 种活性成分，其中大多数是杀菌剂（54%），而实验室分析显示有 23 种化学化合物（52%杀虫剂、39%杀菌剂和 9%除草剂）。此外，二硫代氨基甲酸盐、菌核净和一些有机磷酸酯类化合物在活性成分中名列前茅，其残留量超过了最大残留限量（MRLs）。约 80%的鉴定出的农药未在监管机构 Instituto Colombiano Agropecuario（ICA）进行登记，以供在生菜上使用，但其中一些农药在拉丁美洲和加勒比国家的合法注册的商业产品中存在。
