dc.description.abstractThe present investigation was undertaken to study the dissipation kinetics of metribuzin and its effect on soil enzymes. The residues of metribuzin from soil were extracted using matrix solid phase dispersion. Dissipation of metribuzin followed first order kinetics and half life ranged from 15.57 to 45.07 days days in three soils. Physicochemical properties of soil, application rate and temperature have differential influence on dissipation behaviour of metribuzin. Dissipation rate of metribuzin increased with increase in soil organic matter content and temperature. In enzyme assay studies, effect of metribuzin on three soil enzymes viz. dehydrogenase, alkaline phosphatase and urease was investigated. Metribuzin application significantly affected the soil dehydrogenase and alkaline phosphatase activity. However urease activity remained unaffected by application of metribuzin. Soil dehydrogenase, alkaline phosphatase and urease activity were significantly affected by soil type and temperatureen_US
