To investigate the effect of crop topping cereals for annual ryegrass control with nonselective herbicides.
Key messages
All herbicide treatments reduced grain yield by 13% in TOS 1 and at least 8% in TOS 2.
Glyphosate (540 g/L) at 3.0L/ha was the only treatment to significantly reduce germination, down to 7% at TOS 1 and 88% at TOS 2.
For each application timing glyphosate (540 g/L), glufosinate (200g/L) and paraquat (250g/L) significantly reduced the germination percentage of ryegrass.
