Abstract
Residual herbicides are an important tactic for the extended control of weeds in Australia’s northern grain region (NGR) cropping systems. The use of residual herbicides, for both fallow and in-crop weed control, has increased in recent years, with up to 45% of the cropped area routinely receiving a pre-emergent herbicide application (Llewellyn et al. 2016). This increase is largely in response to an observed increase in resistance to glyphosate in difficult to control summer weeds including feathertop Rhodes grass, flaxleaf fleabane, common sowthistle and awnless barnyard grass. The persistent nature of residual herbicides can cause damage to subsequent, susceptible crops. This is a key consideration in northern region farming where both summer and winter crops can be grown.
