The invention belongs to the technical field of microorganisms and application thereof, and particularly relates to a low-temperature-resistant toprazole
fluridone degrading bacterium and application thereof. The strain is
Cupriavidus, the
Cupriavidus is preserved in the China General
Microbiological Culture Collection Center on July 22, 2025, and the preservation number of the
Cupriavidus is CGMCC (China General
Microbiological Culture Collection Center) No.35332. The strain and the
fungicide can accelerate the
degradation process of the toprazole
fluridone under a low-temperature condition, and are beneficial to enriching microbiological treatment means for degrading toprazole
fluridone residues in farmland soil. According to the present invention, the purified strain CS1 is prepared into the efficient
pesticide degradation
bacterial agent, such that the topramezone can be effectively degraded in the low temperature environment, the degradation of the
pesticide residue in the farmland soil is promoted, and the migration risk of the
pesticide to crops, underground water and human beings is reduced. Compared with traditional methods such as soil
thermal desorption, chemical oxidation and soil dressing methods, the method is higher in efficiency, lower in cost and easier to operate, and an effective microbial technical solution is provided for degradation of the topramezone under the low-temperature condition.
