ABSTRACT
Imazethapyr is the most common herbicide used for weed management in pulses. A field trial was carried out with imazethapyr 10% SL formulation at 100 and 150 g a.i./ha application rates, as pre-and post-emergence, to study dissipation of imazethapyr in soil, persistence in urdbean plant, terminal residues in urdbean grains and effect on soil microbes. An acetate buffered- quick, easy, cheap, effective, rugged, and safe (QuEChERS) method in combination with high-performance liquid chromatography (HPLC) was validated for imazethapyr residue analysis. The half-life of imazethapyr in soil ranged from 15.12 to 18.02 days. The residues of imazethapyr persist up to 60 days in soil and up to 7-15 days in urdbean plant. Residues were not detected in grains at the time of harvest. Persistence of imazethapyr residues in soil significantly impact soil microbial populations depending on herbicide application rates and timing.
