Abstract

Butachlor has been extensively used to control weeds globally. In this study, the degradation performances of butachlor in soil by attenuation, augmentation with Pseudomonas sp. But1 and Pseudomonas sp. But, and mung bean (Vigna radiata L.) cultivation were determined. The results showed that the overall degradation rates in soil over 30 days were as follows: sterilized soil < non-sterilized soil < mung bean cultivation < bioaugmentation. The dissipation of the herbicide in non-sterilized soil was observed to be 58.3 ± 5.5%, while butachlor was completely removed from soil with both bioaugmentation and mung bean cultivation after 30 days. Moreover, mung bean cultivation stimulated rhizospheric bacteria growth and enhanced the degradation. These results showed that both bioaugmentation and mung bean cultivation significantly increased the butachlor degradation in soil.
