Cyantraniliprole is an anthranilic diamide insecticide used for the effective management of diamondback moth in cabbage. Dietary risk assessment of pesticides in food is a major concern now. This study developed a QuEChERS/HPLC-PDA-based highly efficient and reliable method, registering 89.80–100.11% recoveries of cyantraniliprole and its metabolite IN-J9Z38 from cabbage and soil with a relative standard deviation of 0.43–5.77%. Field experiment was conducted to study the residue dissipation of cyantraniliprole in cabbage and soil. Two foliar treatments of 10.26% formulation (Benevia) at 60 (T₁) and 120 (T₂) gram active ingredient/hectare were applied. The dissipation half-lives of cyantraniliprole in cabbage and soil were determined to be 3.5–4.2 and 3.8–5.3 days at T₁ and 3.9–4.8 and 4.1–4.7 days at T₂, respectively. The maximum concentrations of IN-J9Z38 at T₁ and T₂ were 0.819 and 1.061 mg/kg, respectively, on the fifth day. A risk quotient value of <1 indicates no dietary risk to the consumers. The residues in the harvested cabbage were below the tolerance level of 2.0 mg/kg established by the regulatory body in India.

使用 QuEChERS/HPLC-PDA 和膳食风险评估对卷心菜/土壤中田间产生的氰虫酰胺和 IN-J9Z38 残留进行定量

Cyantraniliprole 是一种邻氨基苯甲酰胺类杀虫剂，用于有效防治卷心菜中的小菜蛾。食品中农药的膳食风险评估现在是一个主要问题。本研究开发了一种基于 QuEChERS/HPLC-PDA 的高效且可靠的方法，从卷心菜和土壤中获得 89.80-100.11% 的氰虫酰胺及其代谢物 IN-J9Z38 的回收率，相对标准偏差为 0.43-5.77%。通过田间试验研究了氰虫酰胺在甘蓝和土壤中的残留消散。_{以 60 (T 1} ) 和 120 (T ₂ ) 克活性成分/公顷施用两种 10.26% 制剂 (Benevia) 的叶面处理。_{在 T 1}时，青虫酰胺在卷心菜和土壤中的消散半衰期分别为 3.5-4.2 和 3.8-5.3 天_{在 T 2}和 3.9-4.8 和 4.1-4.7 天，分别。_{在第 5 天，T 1}和 T ₂时 IN-J9Z38 的最大浓度分别为 0.819 和 1.061 mg/kg。<1 的风险商值表明对消费者没有饮食风险。收获的卷心菜中的残留量低于印度监管机构规定的 2.0 mg/kg 的耐受水平。
