Abstract:
In order to study the persistence and degradation of oxyfluorfen from three different types of soils viz., sandy, sandy loam and clayey soil, sandy soil was collected from Agronomy Farm of Sardar Krushinagar Dantiwada Agricultural University, Dantiwada. Sandy loam soil was collected from Bidi Tobacco Research Station Farm of Anand Agricultural University, Anand and clayey soil from Organic Farm of Navsari Agricultural University, Navsari. The persistence of oxyfluorfen in different soils followed first order degradation kinetics and dissipated in one phase. The residues of oxyfluorfen recorded in sandy soil on 0 day was 0.408 µg g-1 with half-life (DT50) of 43.00 days. The residues of oxyfluorfen recorded in sandy loam soil on 0 day was 0.496 µg g-1 with half-life (DT50) of 60.20 days. The residues of oxyfluorfen recorded in clayey soil on 0 day was 0.498 µg g-1 with half-life (DT50) of 75.25 days. The order of persistence of oxyfluorfen in soil denoted by half-life i.e. DT50 observed in the experiment were as follows: Clayey soil (75.25 days) > Sandy loam soil (60.20 days) > Sandy soil (43.00 days).
