title: Field dissipation of metamitron in soil and sugar beet crop.
abstract: Bioaccumulation of herbicides in plant produce may cause ailing effect on animals and human beings through food chain contamination. Thus oblige the investigation of newer herbicide metamitron for its persistence and degradation in sugar beet crop and soil. Metamitron persist in plant up to 15 days while up to 30 days in soil. Its dissipation followed first order reaction kinetics. On day 90, metamitron was detected in the soil at 7.0 kg a.i. ha(-1) treated plot only. It would be concluded that metamitron at 3.5 kg a.i. ha(-1) can be safely applied to the sugar beet crop for weed control.
