Dissipation Kinetics of Bentazone Herbicide in Different pH Waters

Modern agricultural production depends significantly on the use of herbicides to control weeds in crops. There are many herbicides which can be classified into several chemical classes in accordance with their chemical structures. Acidic herbicides like bentazon are widely used for control of broad-leaved weeds and other vegetation. They are relatively inexpensive and very potent even at low concentrations. Bentazon is considered to be a transient herbicide which leaches through the soil into the ground water and may pose problems for the groundwater resources (Pinto et al 1999). Contaminated soil and water are major environmental and human health problems which can be partially solved by phytoremediation.
