| dissipation kinetics of beta-cyfluthrin and imidacloprid in brinjal and soil under subtropical conditions of punjab, india. | dissipation of beta-cyfluthrin and imidacloprid was studied following three applications of a combination formulation of solomon 300 od (beta-cyfluthrin 9% + imidacloprid 21%) @ 60 and 120 g a.i. ha(-1) at 7 days interval. samples of brinjal were collected at 0, 1, 3, 5, 7, 10 and 15 days after the last application and residues of beta-cyfluthrin and imidacloprid were estimated on gas liquid chromatography (glc) and high performance liquid chromatography (hplc), respectively. half-life periods f ... | 2010 | 19936997 |
