Abstract

The aim of the study was to find out the dissipation rate of the chlorantraniliprole residues in garden bean pods. Insecticides were sprayed at the farmers’ holding located at Naraseepuram, Coimbatore during the year 2022 (March to April), and the collected samples were processed and analyzed in the laboratory. An effective modified QuEChERS method was developed and validated to estimate the chlorantraniliprole residues in Ultra High-Performance Chromatography. Good linearity with R2 greater than 0.99 was achieved with the Limit of Quantification as 0.05 mg/kg. The relative standard deviation was below 5% for the recoveries obtained (93.30 to 97.91%). The residues persisted up to 10 and 15 days after treatment for recommended (20 g a.i./ha) and double the recommended doses (40 g a.i./ha), respectively. The half-life of chlorantraniliprole in garden beans was calculated as 2.18 days for recommended dose and 2.89 days for double the recommended dose. Intake of chlorantraniliprole residues through garden beans at either of the doses was found to be safe as the calculated Risk Quotient (RQ) was less than one.

菜豆(Lablab purpureus var. typicus)中氯虫腈残留耗散动力学及食性风险评价

本研究的目的是了解氯虫腈在菜豆荚中残留的消散速率。2022年(3月至4月)在哥印拜陀Naraseepuram的农民农场喷洒杀虫剂，并在实验室对收集的样本进行处理和分析。建立了高效液相色谱法测定氯虫腈残留量的改进QuEChERS方法。定量限为0.05 mg/kg，线性关系良好，R2 > 0.99。加样回收率为93.30% ~ 97.91%，相对标准偏差小于5%。在推荐剂量(20克a.i./公顷)和两倍推荐剂量(40克a.i./公顷)处理后，残留分别持续10天和15天。氯虫腈在菜豆中的半衰期为推荐剂量为2.18 d，两倍推荐剂量为2.89 d。两种剂量的菜豆对氯虫腈残留的摄入都是安全的，计算出的风险商(RQ)均小于1。

期刊介绍： The Research on Crops is a peer-reviewed journal publishing original research papers, review articles and short communications in English on all basic and applied aspects of crop sciences, agricultural water management, agro-climatology, agroforestry, agronomy, crop production, crop protection, cropping systems, food science & technology, genetics & plant breeding, horticulture, plant & soil science, plant biotechnology, plant nutrition, post-harvest management of crops, seed science, soil management & tillage, vegetables, weed science, agricultural engineering, agri-business, agricultural economics and extension, etc. The aim of the journal is to provide a forum for the scientific community to publish their latest research findings. The manuscripts submitted for publication should not contain data older than 4 years on the date of submission. The articles submitted for publication in this journal should not be submitted elsewhere simultaneously for publication in another journal. These should not carry any copyright material without prior permission of copyright holder. The articles should present a complete picture of the investigation made and should not be split into parts. There is no prescribed limit regarding the number of pages in case of full-length articles. However, the authors are advised to keep the length of their articles from 4 to 10 full printed pages of the journal. The articles should be divided into the sub-sections: ABSTRACT, INTRODUCTION, MATERIALS AND METHODS, RESULTS AND DISCUSSION, CONCLUSIONS, and REFERENCES. Tables and figures should be appended separately at the end.
