Degradation Of Herbicide Butachlor And Its Bioaugment In Crop Rhizosphere Soils

Degradation dynamics of the herbicide butachlor were investigated in nonrhizosphere soil, and various crops rhizosphere soils with or without inoculation treatment. The population dynamics of the cultureable microorganisms capable of utilizing butachlor as sole C and energy source were estimated with Most Probable Number method in the process of butachlor degradation.Degradation dynamics of butachlor at concentration of 1, 10, 50mg/kg in the nonrhizosphere soil were measured to be C = 1.40
