Control of common waterhemp varied by as much as 33% depending on the specific nozzle, carrier volume, or travel speed utilized. In this study the use of XR nozzles provided more consistent control of common waterhemp than applications with the AI nozzles. The data also suggests that applications with XR nozzles are not affected by application travel speed, whereas travel speed differentially affected control at both locations with AI nozzles. The data also supports previous findings that common waterhemp control was greatest with applications at lower carrier volumes with either nozzle type. Spray coverage was less important for common waterhemp control than the carrier volume in which glyphosate was applied.
