Keywords:
Mycotoxin, aflatoxin, groundnut, infection, colonizationAbstract
To detect Aspergillus flavus producing aflatoxin in groundnut fifty groundnut samples were collected from local market shop of Muktainagar. All these fifty groundnut samples collected are of summer season produced only during the month of October 2023.All these collected samples were incubated on Czapek-Dox Rose Bengal Agar medium and examined for the fungal growth of Aspergillus flavus producing aflatoxin in groundnut in terms of percentage infection and colonization. The result of total fifty groundnut kernels samples screened for detection of Aspergillus flavus observed that out of total fifty groundnut kernels samples, the minimum and maximum infection range was found from 10 to 50 % and for colonization it stand between10 to 40%. For infection 21 sample (42%) was found completely nil, followed by13 (26%) with less than 25 % infection. Sixteen samples (32%) were observed between greater than 25 to 50 percent range of infection. The result for colonization is interesting where 25 samples (50%) was found completely nil followed by 17 (34 %) and 8 (16 %) found in the percentage range of less than 25 and greater than 25 to 50 for colonization respectively.
