To evaluate the impact of split application of herbicides for grass control pre-plant and in-crop
This trial highlights the importance of residual herbicide application prior to FTR emergence. Despite very low levels of incorporating rainfall, applications of either Dual Gold or Valor ~7-11 weeks prior to planting provided very effective levels of control. In contrast, ineffective FTR control was achieved from all Dual Gold treatments applied only at-planting or in-crop. Improved FTR efficacy from sequential application was most apparent from the July application of Dual Gold with the at-planting ’topped-up’.
Useful data on the length of in-crop efficacy from the sequential treatments was not possible as effective knockdown control of emerged seedlings at planting could not be achieved.
