| dissipation kinetics of spinosad on cauliflower (brassica oleracea var. botrytis. l.) under subtropical conditions of punjab, india. | residues of spinosad were estimated in cauliflower curds using high performance liquid chromatography (hplc) and confirmed by high performance thin layer chromatography (hptlc). following three application of spinosad (success 2.5 sc) at 15 and 30 g a.i. ha−1, the average initial deposits of spinosad were observed to be 0.57 and 1.34 mg kg−1, respectively. these residues dissipated below the limit of quantification (loq) of 0.02 mg kg−1 after 10 days at both the dosages. the half-life values (t ... | 2009 | 19672547 |
