Abstract:Long-term data from 449 herbicide trials across Germany from 1995–2022 were used to characterise the weed composition in sugar beet cultivation.

The most common weeds were Chenopodium album (82.3% of all plots), Polygonum convolvulus (52.2%) and Galium aparine (25%). The average number of weed species in the field trials decreased from 4.9 in 1995 to 2.6 in 2022, significantly influenced by trial location a… Show more
