It is used as pre-emergence herbicide in the control of broadleaf and grassy weeds in a variety of commercial crop as well as roadside and fallow fields (Munier-Lamy et al., 2002).

Criteria were established for detecting microbial cells among the residual soil debris. The functional diversity of the soil microflora was assessed based on microbial processes (N mineralization, ammonium oxidation, arginine deaminase) as well as on the activities of soil enzymes (protease, urease, xylanase, phosphatase, arylsulphatase).
