Chemistry:Ethofumesate
Ethofumesate is a pre- and post-emergence[1] benzofuran 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][3] 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.[1] Ethofumesate is a Group J (Australia), K3 (Global), Group 15 (numeric), resistance class herbicide.[4]
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]
Nortron is an ethofumesate emulsifiable concentrate from Nor-Am.[5]
