Year: 2024
Type: article
Abstract: The present investigation was conducted in the Department of Entomology, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (H.P).Persistence of tebuconazole and combination of fipronil + imidacloprid in chilli field soil was studied following the application at single dose 215 and 50 + 50 g a.i.ha -1 and double dose 430 and 100 + 100 g a.i.ha -1 after spray, respectively.Spray application on the crop leads to initial deposits of tebuconazole, ∑fipronil and ∑imidacloprid in soil as 0.104, 0.105 and 0.103 mg kg -1 at single dose and 0.204, 0.198 and 0.209 mg kg -1 at double dose, respectively.The samples were extracted with acetonitrile and cleaned up using a modified QuECheRS technique.The residues of tebuconazole, ∑fipronil and ∑imidacloprid were analysed on GC-ECD (Gas Chromatography-Electron Capture Detector, GC-MS (Gas Chromatography-Mass Sphectrometry) and HPLC (High Performance Liquid Chromatograph).The limit of quantification for tebuconazole, fipronil and imidacloprid was calculated to be 0.05, 0.001 and 0.05 mg kg -1 , respectively.
