Abstract: 

This study was conducted to evaluate the efficiency gas fumigation from Vinegar5% and Ammonia powder for eradication the contamination fungi Aspergillus flavus, A. niger, Fusarium verticillioides and Penicillium albobivertcillius  in corn grains artificially infested with fungi to expose gas fumigated in desiccators for 30minutes, one hour and 24hour for control the contamination fungi, and the treatment efficiency was evaluated using WA 2% in Petri dishes, to determine an effective and easy-to-apply method that prevents or reduces contamination in grains intended for consumption. The results showed that all volatile compounds had significant effects on fungal control. The fungal incidence was decreased under the effect of Vinegar5%, whilst ammonia powder was effective in eliminating fungi as after 5-7 days of cultivating the kernels on the WA medium and incubating at a temperature of 25 ± 2°C, no fungal growth appeared, and fumigation for 24 hours was the most efficient in eradicating compared with 56,72,82 and 24 respectively in control treatment.

Keywords: Fumigation, Vinergar5%, Ammonia powder, Fungi, Corn grains.
