	*USE OF AMMONIA GAS IN THE CONTROL OF ASPERGILLUS FLAVUS* INFECTION AND AFLATOXIN PRODUCTION IN SUNFLOWER SEED SHAHNAZ DAWAR AND A. GHAFFAR Abstract:** Sunflower seeds inoculated with Aspergillus flavus reduced seed geemination with greater production of aflatoxin during storage. Use of ammonia gas although reduced seed germination but infection of A. flavus decreased with consequent reduction in aflatoxin production. Use of ammonia gas for 15 minutes was fonnd optimum for significant supression of the production of aflatoxin B₁ and 5 minutes for aflatoxin B₂.
