Spot application of flupropanate results in high mortality of Sporobolus pyramidalis
2024
Warren, Clare | Vogler, Wayne D.
Liquid flupropanate applied by spot application was tested on Sporobolus pyramidalis (P.Beauv.) to expand control options. Spot application is a high concentration, low volume herbicide mix applied directly into the base of the plant tussock. This application technique is suitable for herbicides such as flupropanate due to it being a predominantly root uptake herbicide and therefore complete foliage coverage is not needed. Applying liquid flupropanate by spot application provides a non-broadcast, species selective herbicide option with limited/no off-target damage. It is a practical method for scattered infestations within pastures, natural areas, roadsides and revegetation sites. The minimal equipment needed also allows plants to be controlled in hard to access areas. Two trials were conducted on different properties within the Gladstone region. Liquid flupropanate (Taskforce® (745 g L-1 flupropanate)) was applied at rates of 0.149, 0.2235 and 0.298 g a.i. tussock-1 and the efficacy was assessed against an untreated control. In both trials, all liquid flupropanate treatments were found to be effective for the control of S. pyramidalis, with 97.8% or higher mortality and no reproductive stems present during the following growing season.
