Isolation and Identification of Alternaria arborscens from corn grains and possibility controlling of it by using Agaricus bisporus filterate and sodium citrate and their toxin

This study included isolating the accompanying and contaminated fungi of Corn Grains in city Al- Diwaniyah collected for period September-December / 2021. A number were identified: it Aternaria arborscens., It was observed that percentage surface associated with non-sterile samples high. Fungal toxins detected fungal leachates one these fungus A. arborescenswas diagnosed phenotype genetically using PCR technology. So this species we have provided GenBank accession number(s) nucleotide sequence(s): ON386194 ON386195 recorded Iraq study. The analysis performed HPLC technology showed results on ability arborescens to produce toxins. highest concentration altratoxin which 247.9 μg ml. In Agaricus bisporus used conduct biological resistance pathogenic reduce its toxicity arborescens. is gave high when testing contrast between them. their prevent growth solid liquid media.
