Abstract

Field experiments were conducted at wetlands of Tamil Nadu Agricultural University. Coimbatore, during 1992-93 to find out the degradation and persistence of anilofos and 2, 4-DEE in soil and their terminal residues in rice grain and straw under direct seeded puddled condition. The results revealed that application of anilofos at 0.4 kg persisted in the soil upto 56 days after treatment. The terminal residue after two successive rice crop was below the level of detection. At higher doses both anilofos and 2,4-D EE residues were recorded in rice grain and straw, but the residue levels were far below the maximum residue limit.
