Ryegrass control in barley using pre-emergent herbicides locations
Aims

To examine rygrass control in barley using pre-emergent herbicides. 

Key messages

Higher rates of Triflur Xcel can only be used in a no‐till system where a knife point and press wheel system operated at a suitable sowing speed ensures that soil throw from seeding rows does not fall into adjacent seeding rows thereby avoiding crop damage.
The high levels of ryegrass control achieved in this trial demonstrate how a concentrated band of trifluralin in the top few cm of soil is highly effective when weed seeds are also in this band. The tank mix partners used in the trial, Bouncer and Avadex Xtra, can provide cost effective control over a range of additional weeds, as well as ensuring control of any possible group D resistant ryegrass plants.
