Abstract:
Suitable for controlling harmful plants in sugar beet crops composed of tolerant or resistant mutants or transgenic sugar beet plants are herbicide combinations (A)+(B), if appropriate in the presence of safeners, with an effective content of (A) broad-spectrum herbicides from the group (A1) glufosinate (salts) and related compounds, (A2) glyphosate (salts) and related compounds such as sulfosate and (A3) imidazolinones or their salts and (B) herbicides from the group consisting of (B0) one or more structurally different herbicides from the abovementioned group (A) or (B1) foliar- and predominantly soil-acting herbicides which are active against monocotyledonous and dicotyledonous harmful plants, or (B2) herbicides which are active predominantly against dicotyledonous harmful plants, and (B3) herbicides which are predominantly foliar-acting and which can be employed against monocotyledonous harmful plants, or (B4) herbicides which are both foliar- and soil-acting and which can be employed against monocotyledonous harmful plants, or of herbicides of more than one of groups (B0) to (B4), the sugar beet crops tolerating the herbicides (A) and (B) present in the combination, if appropriate in the presence of safeners. If appropriate, the combinations are also suitable for regulating the growth or else for controlling the yield or the constituents of sugar beet plants.
