Abstract
Windmill grass is a summer active, native species found throughout Australia. This research found that growth of windmill grass over summer significantly reduced the growth and yield of the following wheat crop (wheat yield of 0.9 t haí1 with no summer weed control, 1.2 t haí1 with summer weed control). Controlling windmill grass is desirable to maximise crop yield, but there are few registered herbicides available. Mature windmill grass in field conditions was successfully killed by glyphosate 540–1080 g a.i. haí1 (Roundup Power Max®), glyphosate 540 g a.i. haí1 followed by paraquat 135 g a.i./ diquat 115 g a.i. haí1 (Spray.Seed®), or haloxyfop 208 g a.i. haí1 (Verdict®). Young plants (in the glasshouse) were also controlled pre-seeding by diuron 990 g a.i. haí1 (Diuron®) and trifluralin 500 g a.i. haí1 (Triflur Xcel®). However, further research is required to identify a broader range of herbicide options for windmill grass control.
