Effective weed management in sugar beet cultivation will become difficult in the future
due to the non-approval of proven herbicidal active agents. In order to guarantee effective
weed control in sugar beet, Zasso and AgXtend developed a new management
approaches for integrated crop protection.
In 2019, electrophysical weed control (Electroherb™) was tested for the first time in a pre-
emergence treatment scenario in mulch sowing cultivation of sugar beet. The
electrophysical weed control was compared with a mechanical method in a field trial with
triple repetitions. The individual plots were divided, half into pre-sowing applications with
and without glyphosate to control old weeds.
The area-treatment with the XPower™ was carried out with a power of 72 kW on a working width of 3 m and driving speeds of 3 and 5 km/h.

Electroherb™ during the treatment of old weeds (mainly fallow rye).
Weed densities on 10 m² (averaged values (n=6), 09.04.2019), 18 days after sugar beet sowing. The following pre-emergence variants: untreated control, Electroherb™ and harrow are displayed, both with and without glyphosate application 25 days before sowing (25.02.2019).
The results of the 2019 field trials have shown that electrophysical weed control leads to
a strong reduction of weed density. In the plots without glyphosate application before
sowing, here Electroherb™ shows that also older weeds can also be controlled
effectively. In view of the low competitiveness in the cotyledon stage of sugar beet,
Electroherb™ treatments in pre-emergence has a positive effect on sugar beet youth
Based on the results of the 2019 trial year, experiments on electrophysical pre-
emergence treatment in sugar beets will be repeated in the 2020 trial year. In order to
establish the Electroherb™ for post-emergence weed control in sugar beet as well, a
between-row applicator will be used between the sugar beet rows for weed control for the
first time in 2020.
