Field study was carried out to investigate persistence and degradation kinetics of trifluralin (48 EC) applied pre emergency in mungbean crop (Variety, Asha) @ 1 Kg ai ha−1 (T1) and 2 Kg ai ha−1 (T2) for the control of broad leaf weeds during kharif 2002. The dissipation on 90 days was around 97% in T1 and T2- Kinetics studies revealed that dissipation of trifluralin residues followed first order kinetics. The half life values observed were 23.3 days in T1 and 26.2 days in T2.
