Effects of Glufosinate-Ammonium and Urea on Aflatoxin and Fumonisin Levels in Corn

H. A. Bruns and H. K. Abbas

March 2006

Research

The objective of this research was to determine if glufosinate-ammonium (G-A) or urea can suppress or inhibit pre-harvest aflatoxin and fumonisin contamination of irrigated corn in the Mississippi Delta. The results indicate that both G-A and urea applied 60 days after silking were ineffective at reducing aflatoxin and fumonisin contamination of corn. These results do not support earlier research on G-A and aflatoxin contamination in corn.
