With the ever-increasing evolution of resistance to post-emergent herbicides there is in several parts of the world an increase in pre-emergent herbicide use.
Of course, it is necessary to achieve high efficacy of pre-emergent herbicides (start clean) as well as diversity and rotation in their use to help their sustainability.
In this paper, Catherine Borger details that under Australian conditions pre-emergent herbicide efficacy is dependent on water volume, with increasing herbicide efficacy with increasing water volume. Maximising pre-emergent herbicide efficacy is important and Catherine Borger shows that appropriate total water volumes can be one important factor in achieving efficacy.
