Abstract:
Taking the pear orchards soils in Southern Xinjiang as research object,bacteria strains were isolated from them which could degrade the effective components of omethoate completely.The degrading strains were identified using 16S rDNA sequences.The degradation spectrum and degradation capabilities of them were studied.The results showed that 3 strains were isolated which could degrade the effective components of omethoate completely，and they were identified as Pseudomonadales sp.，Bacillus spp.and Agrobacterium sp.There were differences among different strains.Of the three bacteria strains，the strain of Pseudomonas sp.DYY-3 exhibited higher degradation capabilities.The data of this study provided the solid foundation for microbial-insecticide mixtures and its field application.
