Aims:

Brome grass is the costliest weed to grain production in the Mallee region despite herbicide resistance being relatively low. This paper brings together research trials from 2015 and 2016 addressing the potential for greater efficacy of pre-emergence herbicides on brome and the potential for better crop competition on non-wetting sands. For grow… read more
