Chlorpyriphos Residues in/on Cabbage and Brinjal

Persistence of chlorpyriphos in/on cabbage head and brinjal fruits was studied in field experiments conducted at the Gujarat Agricultural University, Anand, during rabi 1993–94 and 1995–96, respectively. The residues persisted upto 15 d in cabbage and 10 d in brinjal. The half-life values were 1.0 and 0.3 d for cabbage, when applied @ 0.04 and 0.08 per cent, respectively, while for brinjal it was 0.4 d for both the applications.
