摘要

田间和实验室实验探索了辣椒植株的四烯虫酰胺消散情况。在哥印拜陀 Devarayapuram 村进行的监督试验评估了 CO2 辣椒品种(2018 年 12 月至 2019 年 3 月)。使用快速、简便、廉价、有效、坚固和安全(QuEChERS)方法和超高效液相色谱法(UHPLC),收集了施药后 15 d 的样品。喷洒 1 小时后,辣椒果实上的初始四氟虫酰胺沉积量分别为 0.898 和 1.271 μg g-1(单剂量和双剂量)。超过 80% 的沉积物在 5 天内消散,单剂和双剂分别在第 7 天和第 10 天消散到检测限以下。转化分析倾向于一阶动力学。在推荐剂量和双倍剂量下,辣椒果实上的四氢吡咯半衰期分别为 1.49 天和 1.53 天。60 和 120 g a.i ha-1 的安全等待期分别为 4.16 和 5.04 d。这项研究有助于深入了解辣椒植株中四烯丙环唑的动态,这对有效管理农药至关重要。

Dissipation pattern of tetraniliprole in/on green chilies.

Field and lab experiments explored tetraniliprole dissipation in chili plants. A supervised trial in Devarayapuram village, Coimbatore, assessed the CO2 chili variety (December-March 2018-2019). Using the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method and ultra-high-performance liquid chromatography (UHPLC), samples were collected up to 15 d post-application. Initial tetraniliprole deposits on chili fruits, 1-h post-spray, were 0.898 and 1.271 μg g-1 at single and double doses. Over 80% dissipated within 5 d, reaching below detection limits by day 7 and 10 for single and double doses, respectively. Transformation analysis favored first-order kinetics. Tetraniliprole half-life on chili fruit was 1.49 and 1.53 d at recommended and double doses. The safe waiting period was 4.16 and 5.04 d for 60 and 120 g a.i ha-1. This study provides insights into tetraniliprole dynamics in chili plants, crucial for effective pesticide management.
