Abstract
The efficacy of a granulosis virus isolated in Spain from Agrotis segetum larvae (AsGV) was field tested and compared with chlorpyrifos and flucythrinate as control agents against A. segetum larvae on corn seedlings.The application of the AsGV through bran wheat bait provided a crop protection similar to that produced by chlorpyrifos and flucythrinate. Significant differences were not found between the levels of protection provided by AsGV when it was applied at a rate of 4.1 × 1012 IB/ha or 4.1 × 1013 IB/ha.Zusammenfassung: Wirkung eines spanischen Stammes des Agrotis segetum‐Granulosevirus (Baculoviridae) auf Raupen von Agrotis segetum Schiff. (Lep., Noctuidae) an MaisEs wurde die Wirkung eines in Spanien aus Agrotis segetum‐Raupen isolierten Stammes eines Granulosevirus (AsGV) gegen A. segetum‐Rzupen — im Vergleich zu Chlorpyrifos und Flucythrinat — an jungen Maispflanzen im Freiland getestet. Die Ausbringung des AsGV mittels Weizenkleie‐Ködern führte zu einem Ertragschutz‐Effekt, der in seiner Höhe vergleichbar mit jenem bei Anwendung von Chlorpyrifos und Flucythrinat war. Signifikante Unterschiede bezüglich der Höhe des Schutzeffekts zwischen AsGV‐Raten von 4,1 × 1012 IB/ha und 4,1 × 1013 IB/ha wurden nicht festgestellt.Keywords
