Effect of phosphine (ph3) in controlling aflatoxin production in stored groundnut (Arachis hypogea) and wet maize (Zeamais)
The potentials of phosphine in controlling aflatoxin production by Aspergillus flavus on groundnut and wet maize stored in seaied containers under ambient conditions in the laboratory were studied. Groundnut and wet maize inoculated with spore suspensions of A. flavus and exposed to phosphine in sealed containers for toxin production had a very low mold counts and an aflatoxin B1of less than 5 mg/kg during 6 months storage. The grains remained fresh without loss in quality at the end of storage. Similarly treated groundnut and wet maize stored in air in sealed containers had a very high mold count and aflatoxin B1 contents within 10 and 2 days, respectively. The results of the study will be useful in post-harvest handling of damp grains in the humid zone where the harvesting period of maize coincides with the wet season.
