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. Young weeds absorb ethofumesate through roots and shoots, and the ethofumesate inhibits respiration and photosynthesis. Ethofumesate is a Group J herbicide.^[1]

In soil is ethofumesate biodegraded by soil's microörganisms. 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.^[1]
