Abstract

Field experiments were conducted during rabi 92, summer 93 and kharif 93 to evaluate anilofos 50 EC residues in transplanted rice. The treatments constituted anilofos 50 EC at 0.2, 0.4 and 0.8 kg/ha and anilofos 30 EC at 0.4 kg/ha. The residues of anilofos in soil and plant samples were analysed using HPLC and the results revealed that the soil residues of anilofos were degraded within 56 days at 0.2 kg/ha, within harvest at 0.4 kg/ha and beyond harvest at 0.8 kg/ha respectively. The anilofos residues were at detectable levels in rice grain and straw at 0.8 kg/ha of anilofos 50 EC which again were below the Maximum Residue Limits.
