Controlled release formulations of metribuzin in polyvinyl chloride, (emulsion); carboxy methyl cellulose, CMC and carboxy methyl cellulose- kaolinite composite, CMC-KAO are reported. The MET-CMC-KAO-3 (T9) formulation provided a superior control (76.1%) of weeds in field grown wheat in comparison to metribuzin 75 DF (57.14%) at the dose (350 g a.i. ha−1) after 90 days of sowing. The treatment (T9) reduced the dry weight of the weed flora after 30 days of sowing (4.0 g m−2) and significantly superior over metribuzin 75 DF (6.0 g m−2) and control (17.72 g m−2). There were nil to negligible metribuzin residue in soil at harvest of wheat crop and were within prescribed limit of 10 mg L−1 in drinking water (EPA).
