Deltamethrin, as a widely used pyrethroid insecticide, has caused significant environmental pollution due to its persistence and non-degradability in soil. Therefore, the immobilized microbial technology has shown good application potential due to its low cost and quick effect. Among them, Aspergillus niger as the representative of 17 kinds of bacterial mixed agents has strong tolerance and decomposition effect, can secrete a variety of degradation enzymes, can play a good degradation effect on deltamethrin, and has a broad application prospect, but there are many limitations in the degradation of deltamethrin, and its degradation characteristics still need to be further explored. Therefore, this paper reviewed the current situation of pesticide compound contaminated soil in China, the harm and biological toxicity of pyrethroid pesticides, the application and mechanism of immobilized mixed microbial agents with Aspergillus niger as the main body in the degradation of pyrethroid pesticides, in order to lay a theoretical foundation for the treatment of soil pyrethroid pesticide residues, help realize the practical application of immobilized compound microbial agents in the remediation of soil pollution, and promote the green development of agricultural ecology in China.
