Ethofumesate is a pre- and post-emergence[1] herbicide used on sugar beets to control weeds, notably blackgrasses.
UK registration in 2016 is planned for pre-emergence use on wheat as an auxiliary component of tank mix.
[2] Ethofumesate is used in Australia, to control wintergrasses in turfgrasses, along fencelines and tree plantations.
In soils with over 1% organic matter content, ethofumesate doesn't leach.
The halflife in soil is 5-14 weeks, and residual herbicide activity can last four to eight months.
