Abstract

Field studies were conducted in 1992 and 1993 to determine the effect of atrazine and pendimethalin on velvetleaf competitiveness in corn. The three factors included in this research were herbicide, velvetleaf density (zero or nine plants per meter of row), and treatment (treated with herbicide or untreated). Herbicide treatments consisted of atrazine (0.6 and 1.1 kg/ha) or pendimethalin (0.6 and 1.1 kg/ha) applied preemergence. In 1992 and 1993, both atrazine and pendimethalin applied at 1.1 kg/ha greatly reduced velvetleaf growth and seed production and prevented velvetleaf from reducing corn yield. Both atrazine and pendimethalin applied at 0.6 kg/ha reduced velvetleaf growth and seed production in 1993, but only atrazine prevented yield loss in 1992. In the absence of velvetleaf, corn yield was not affected by either herbicide. These results indicate that sublethal exposure to atrazine or pendimethalin can significantly reduce velvetleaf competitiveness in corn.
