Field trials were conducted to study the magnitude of BPMC and carbaryl residues in and/or on jute foliage. Jute crop was treated with BPMC 50EC, carbaryl 50 WP and Sevimol 40 LV at 0.75 and 1.25 kg a.i./ha, twice at the interval of 15 days, starting 45 days after sowing. The samples of green foliage drawn at different time intervals were analysed colorimetrically. The initial deposits of BPMC and carbaryl in and/or on foliage varied from 73.51 to 103.18 ppm and 91.01 to 137.55 ppm respectively. The residues dissipated fairly rapidly. Dissipation followed a first‐order reaction and the half‐life values for carbaryl and BPMC varied from 2.79 to 3.16 and 2.17 to 2.31 days respectively.
