Abstract


A field study was conducted to assess the dissipation pattern of lufenuron 5.4 EC in/on cabbage and soil. Lufenuron was sprayed thrice at fifteen days interval @ 30 and 60 g a.i./ha. Soil and cabbage head samples were collected at 0 (1 h after spraying), 1, 3, 5 and 7 days after third spray. The initial deposits of lufenuron were 0.196 and 0.327 μg/g from 30 and 60 g a.i./ha, respectively on cabbage. Lufenuron residues persisted up to 5 days in the cabbage treated with 30 g a.i./ha and 60 g a.i./ha. Whereas in soil, residues were below detectable level at both doses. The half life values for the two doses were 1.49 and 1.51 days, respectively. Decline behaviour of dissoluble pesticide residues was computed following seven transformations and the best fit was first order for both treatments. The waiting period suggested after spraying lufenuron 5.4 EC was 7 days.
