Flupyradifurone is a novel neonicotinoid insecticide, mainly used in okra in subtropical conditions for controlling whitefly and jassids. The present experiment was designed to generate information on the leaching behavior of flupyradifurone, 3-[(6-chloropyridin-3-yl)methyl-(2,2-difluroethyl)amino]-2H-furan-5-one, under different rainfall conditions by using packed soil columns. Under the continuous flow conditions, a significant quantity of flupyradifurone, 67.76% and 50.61% were recovered at 0 to 5 cm soil depth in case of both clayey and sandy loam soil, respectively. A considerable amount of the residue was confined to 0 to 20 cm soil depth, with or without farmyard manure (FYM) amendment. Under varying water flow condition, distribution of the residue in the upper 0 to 5 cm soil depth got enhanced (> 90% recovery). Among the test soils, residues were detected from the leachate fraction of sandy soil (0.08 µg/mL) only. The study pointed out that leaching of flupyradifurone in sandy loam soil got decreased after using FYM. The leaching of flupyradifurone increased with the increasing amount of water (40 to 160 mL) and the residues continued to travel down to the lower depth. It can be concluded that the use of FYM may be a viable option for reducing the mobility of flupyradifurone in sandy loam soil.

氟啶呋酮是一种新型的新烟碱类杀虫剂，主要用于亚热带地区的秋葵防治粉虱和虻。本实验旨在生成有关氟吡呋喃酮、3-[(6-氯吡啶-3-基)甲基-(2,2-二氟乙基)氨基]-2H-呋喃-5-酮在不同降雨量下的浸出行为的信息条件通过使用填充土柱。在连续流动条件下，在粘土和砂壤土的情况下，在 0 至 5 cm 土壤深度处分别回收了大量的氟吡呋喃酮，分别为 67.76% 和 50.61%。大量残留物被限制在 0 至 20 厘米的土壤深度，无论是否添加农家肥 (FYM)。在不同的水流条件下，残留物在上部 0 至 5 cm 土壤深度的分布得到增强（> 90% 回收率）。在试验土壤中，仅从沙质土壤的渗滤液部分中检测到残留物 (0.08 µg/mL)。研究指出，使用FYM后，氟吡呋酮在沙壤土中的淋失减少。氟吡呋喃酮的浸出量随着水量（40 至 160 mL）的增加而增加，并且残留物继续向下移动到较低的深度。可以得出结论，使用 FYM 可能是降低氟吡呋喃酮在沙壤土中迁移的可行选择。
