Field and greenhouse trials were conducted to evaluate application variables including spray volume, surfactant, and simulated rain affecting phytotoxicity of Glyphosate for enhancing efficacy of postemergence herbicides. Glyphosate phytotoxicity was increased by addition of surfactants, L-77 and Triton CS-7 to Glyphosate solution in Artemisia princeps and Equisetum arvense and addition of Triton CS-7 to Glyphosate solution enhanced control of Trifolium repens. Simulated rain within 4 or 8 hours after Glyphosate application reduced Glyphosate phytotoxicity. However, addition of L-77 and Triton CS-7 to Glyphosate solution increased Glyphosate phytotoxicity reduced by simulated rain in Artemisia princeps and Trifolium repens
