Croupier - a broad spectrum cleaver effective herbicide as an innovative liquid formulation for the use in cereals

Abstract

The new herbicide Croupier contains the active ingredients Fluroxypyr (225 g/L, formulated as mepthylester) and metsulfuron-methyl (9 g/L) from two different classes of active ingredients, combined in a liquid leaf active formulation. With an application rate of 0.67 L/ha for the use in spring Croupier shows a high efficacy against cleavers and a broad spectrum of dicotyledonous weeds in all important cereals except oats. Croupier is characterized by a rapid absorption of the active ingredients, a broad weed spectrum and a large application window (BBCH 20-39 in winter cereals and BBCH 13-39 in spring cereals). Next to the early date of application there is also a late use of Croupier against root weeds possible.
Several years of pan-European field trials demonstrate the efficacy of Croupier e.g. against cleavers, a variety of annual dicotyledonous weeds, cruciferous plants in general as well as difficult to control weeds like beaked parsley (Anthriscus caucalis), fools parsley (Aethusa cynapium) and other umbellifers.
