Abstract/Contents:"Field and greenhouse studies were conducted in 2000 to determine the effect of glyphosate, glufosinate, and imazethapyr rates and application timing on black nightshade, common waterhemp, eastern black nightshade, field bindweed, giant ragweed, ivyleaf morningglory, Palmer amaranth, prairie cupgrass, velvetleaf, and yellow nutsedge control. Herbicides were applied at 0, 0.25X, 0.5X, and 1X the use rate of 1121, 410, and 70 g/ha for glyphosate, glufosinate, and imazethapyr respectively in both the greenhouse and field studies. In the greenhouse study, control with glyphosate and glufosinate was greater than imazethapyr for all species at the 0.5X and 1X rates. Glyphosate gave greater or equal control to that of glufosinate for all species except yellow nutsedge, ivyleaf morningglory, and giant ragweed, which were best controlled by glufosinate. In the field study, glyphosate gave the greatest control of common waterhemp, ivyleaf morningglory, Palmer amaranth, and velvetleaf when applied at weed heights of 17-38 cm and 25-58 cm regardless of herbicide rate. Lower control of ivyleaf morningglory with glufosinate in the field was probably due to larger plants, increased canopy development, and poor herbicide coverage in the field compared to the greenhouse."
