Dissipation kinetics and consumer risk assessment of novaluron + lambda-cyhalothrin co-formulation in cabbage.

摘要: Abstract Cabbage, one of the most popular vegetables in world is infested by several insect-pests and diseases. Novaluron, a chitin synthesis inhibitor lambda-cyhalothrin, synthetic pyrethroid group insecticide are used to manage on cabbage. The dissipation kinetics risk assessment combination formulation (novaluron 9.45% + lambda-cyhalothrin 1.9%) with different modes action has not yet been investigated Multi–location supervised field trials were therefore, conducted agro-climatic regions India for safety evaluation product. co-formulation at recommended 750 g a.i. ha−1 ha−1) double 1500 g dose was sprayed cabbage crop. samples extracted cleaned up using modified QuEChERS method, residues analyzed GC–ECD GC–MS. half-life (t1/2) varied between 1.77 2.51 2.00–3.38 days novaluron 1.36–2.24 1.69–3.82 respective doses. Food Safety Standards Authority (FSSAI) set MRL 0.7 mg kg−1 PHI 5 days, no On basis OECD calculator, MRLs 0.6 1.5 mg kg−1 respectively calculated doses 3 days. Hazard quotient (HQ)
