To explore herbicide interactions across depths of sowing to investigate crop safety and ways of adjusting/changing IBS and EPE herbicides.
The herbicide screen in Meckering found no significant difference in emergence rates for any sowing depth or any IBS herbicide applied on the 28th of May. Plant sampling found coleoptiles to be thicker for most treatment containing Trifluralin in shallow (35 mm) sown plots (figure 20). Thickening was not as pronounced for the same treatments where sown deep (100 mm).
Similarly, coleoptile lengths showed shortening for various treatments for shallow sowings, particularly for 500 mL/ha Luximax + 2 L/ha Trifluralin treatment, and for 120 g/ha Terrain + 2 L/ha Trifluralin treatment. Deep sown treatments had little to no coleoptile shortening effects (figures 21 and 22).
