The proliferation of glyphosate products into the glyphosate-resistant crop market is unprecedented. Due to widespread public interest in these products, field experiments were conducted to compare the efficacy of various glyphosate herbicides on weed control at six locations across Nebraska in various cropping systems. In eastern Nebraska, all herbicide treatments provided excellent weed control (> 90%) regardless of the rate or brand name. In Western Nebraska, herbicide rate and the year were significant, but there was no significant difference among glyphosate brands. In general, generic glyphosate products provided equal level of weed control compared to the usually more expensive brand name products.
