- Abstract
Studies were conducted to evaluate the harvest time residues of spinosad, composed of spinosyn A and D, an insecticidal derivative from fermentation of soil actenomycete species Saccharopolyspora spinosa from cardamom capsules and its cropped soil. Two sprays of spinosad 48 SC at 25 and 50 g a.i. ha-1 were given along with untreated check. Samples of green cardamom capsules and soil were collected at random at thirty days after last spray for analysis. The residues were estimated utilizing high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection for determining spinosad and its metabolites by Hitachi 6200 L Model. The results revealed that the harvest time residues of Spinosad 48 EC at 25 and 50 g a.i. ha-1 were below detectable level in green and cured cardamom capsules and soil samples.
