Dissipation behaviour of novaluron SC was investigated in tomato fruits sprayed at (single dose) and g . ha-1 (double dose). Tomato fruits samples were collected periodically on 0 (1h after application), 1, 3, 5, 7, 10, and 15 days after application. Average recoveries of novaluron in tomato fruits fortified at to mg kg-1 levels ranged from to per cent. The initial deposits of novaluron were and mg kg-1 at single and double dose, respectively. Dissipation of novaluron fitted well to first order kinetics with half-life values ranging from to days at single and double doses, respectively. Residues of novaluron decreased substantially during household processing among which peeling was found most effective which resulted 80 % reduction in both the doses. LOD and LOQ were found to be and mg kg-1 , respectively. | Dissipation behaviour and effect of different decontamination processes on reduction of residues of novaluron in tomato Lycopersicon esculentum Mill.
