Möhrenfliege Rostbraune Fraßgänge mit 6-9 mm langen Maden, Quelle: DLR-RNH
- Rostbraune Fraßgänge mit 6-9 mm langen Maden im Rübenkörper
Beachten
- Fliege bevorzugt windgeschützte, feuchte Lagen
- An Feldrand höherer Befall
- Eiablage ab Mitte-Ende Mai, Frühsätze bleiben meist befallsfrei
- Befallskontrolle möglich mit gelben Leimtafeln: Bekämpfungsschwelle: 1. Generation 1 Fliege/Tag und Tafel, 2. Generation 2 Fliegen/Tag und Tafel
Vorbeugen
- Windoffene Lagen wenig gefährdet
- Großflächiger Anbau mit geringem Feldrandanteil senkt Befallswahrscheinlichkeit
