Abstract: The inhibition effect of kelp residue microbial fertilizer on mycotoxin-producing fungus Aspergillus parasiticus was studied. The kelp residue microbial fertilizer was fermented with bio-control Bacillus Hitwh-BA2. Results showed that kelp residue microbial fertilizer have extremely significantly reduced the number of A. parasiticus and A. parasiticus percentage of total number of fungi, and its effect was better than kelp residue; kelp residue microbial fertilizer have extremely significantly improved the number of bacteria in cultivated soil, and the effect of kelp reside microbial fertilizer and kelp residue were extremely significant difference. The results suggestted that kelp residue microbial fertilizer could be used in biocontrol of aflatoxin-producing fungi in soils.

Key words: kelp residue microbial fertilizer, kelp residue, Aspergillus parasiticus, ecological control
