Glyphosate was tested on bermudagrass, guineagrass, and purple nutsedge with different adjuvants to see how well it controlled the weeds. When Frigate was added, bermudagrass control stayed good even with less glyphosate, but control decreased without adjuvants. Purple nutsedge control was best with LI-700 in the mix. All adjuvants helped glyphosate work better on guineagrass at a higher dose, but not at a lower dose. The adjuvants used were Frigate, LI-700, and VPG.
