Auflaufende Rüben zeigen Fraßstellen an Wurzel und Wurzelhals oder haben abgefressene bzw. gestutzte Keimblätter.
Maßnahmen zur Schadensminderung
- Rübenbau erst nach 3-jähriger Anbaupause.
- Förderung der Jugendentwicklung durch zeitgerechte, nicht zu frühe Aussaat und Vermeidung von Belastungen durch zu hohe Salzkonzentrationen aus der Düngung und durch Herbizide.
- Herbstfurche, denn lockerer Boden mit Hohlräumen gibt lichtscheuen Käfern und Larven gute Lebensbedingungen.
