Aims
To determine the effect of stubble management (standing, slashed or burnt) on the crop safety of pre-sowing herbicides, and their efficacy against Group A-resistant annual ryegrass.
Key messages
In 2007, herbicides applied to burnt stubble were more effective than those applied to slashed stubble. In 2008, there was no effect of stubble management on efficacy or crop safety.
All herbicide treatments gave adequate control ofryegrassin both years, but TriflurX® 1.5L/ha + Avadex Xtra® 1.6L/ha gave the best control in both 2007 and 2008.
Improved control of ryegrass did not increase yield, and the most profitable treatments were the lower rates of trifluralin.
Standing stubble substantially increased grain yield relative to slashed stubble (0.41 and 0.47t/ha in 2007 and 2008 respectively).
