| Abstract: | The persistence and dissipation pattern of dazomet residues in nursery bed soil and tomato seedlings under field condition and in submerged soil and surface water under laboratory condition was studied. In nursery bed soil the half life (t 1/2) of dazomet ranged from 1.85 to 3.09 days indicating very rapid dissipation. No residues existed in tomato seedlings sown on the treated plots 3 weeks after application and the seedlings were healthy and devoid of any deformation. Under submerged condition dissipation was much faster both in soil and surface water, t1/2 being 0.82–0.84 days only in water. |
