Abstract

                                Harvest time residues of abamectin 1.9 EC after four applications at 14 days interval on cotton @ 10.8, 14.5, 18.5, 22.5 and 29.0 g a.i.ha -1 were determined in seed, lint and oil using high performance liquid chromatography (HPLC) equipped with F-1050 fluorescence detector. The interval between the last spray and first harvest was 37 and 34 days in the first and second field experiments, respectively. The harvest time residues of abamectin were at below detectable level (BDL) in cotton seed, lint and oil sample at all the concentrations tested.
