Many insecticides are recommended for use on cruciferous crops in India. Novaluron is one of the insect growth regulator in use to control insect pests on cruciferous crops. A method was developed for analysis of novaluron residues in cauliflower curd. The LOD and LOQ was 0.03 and 0.07 mg kg−1, respectively and the recovery achieved were in the range of 82.7 and 85.7%. Field experiment was carried out to study the dissipation of novaluron in cauliflower curd. The residues persisted beyond 15 days. The half-life was 2.4 days and safe waiting period was 7.9 days. The present study is useful for the careful use of novaluron and to fix the safe waiting period on the cauliflower.
