A field experiment was undertaken at Indian Agricultural Research Institute, New Delhi during kharif (rainy season) in the year 2010 to evaluate the residue persistence of flubendiamide in/on okra fruits following foliar application of Belt 39.35% SC formulation at 24 (standard dose) and 48 (double dose) g a.i. ha(-1). After HPLC analysis study revealed that residues of flubendiamide in/on okra persisted till 5th and 7th day after the last spray at standard and double dose, respectively. The residues of flubendiamide were reported as parent compound, and des-iodo flubendiamide, a metabolite (photo product) of flubendiamide, was not detected in/on okra at any time during the study period. The initial deposits of 0.28 and 0.53 μg g(-1) in/on okra fruits reached below determination level of 0.01 μg g(-1) on the 7th and 10th day at standard and double dose, respectively. The half life of flubendiamide in/on okra fruits ranged from 4.7 to 5.1 days at standard and double dose, respectively. Soil sample collected from the treated field on the 15th day after the last spray revealed residues of flubendiamide or its metabolite below determination level (0.01 μg g(-1)) at single and double dose.
2010 年，在印度农业研究所（新德里）的雨季进行了田间试验，以评估在标准剂量（24 克有效成分/公顷）和双倍剂量（48 克有效成分/公顷）下叶面施用 Belt 39.35% SC 制剂后，在秋葵果实中氟苯虫酰胺的残留情况。HPLC 分析研究表明，在最后一次喷雾后第 5 天和第 7 天，在秋葵果实中的氟苯虫酰胺残留分别持续到标准剂量和双倍剂量。残留的氟苯虫酰胺被报告为母体化合物，而氟苯虫酰胺的代谢物（光产物）去碘氟苯虫酰胺在研究期间的任何时候都未在秋葵中检测到。在标准剂量和双倍剂量下，秋葵果实中初始沉积量为 0.28 和 0.53μg g(-1)，分别在第 7 天和第 10 天达到低于 0.01μg g(-1)的检测限。氟苯虫酰胺在秋葵果实中的半衰期在标准剂量和双倍剂量下分别为 4.7 至 5.1 天。在最后一次喷雾后第 15 天从处理过的田间采集的土壤样本显示，氟苯虫酰胺或其代谢物的残留量低于检测限（0.01μg g(-1))，无论是在单一剂量还是双倍剂量下。
