Definitions

• the present invention is in the technical field of crop protection agents which are effective against undesirable plant growth, e.g. can be used in plant crops.
• the invention relates to a herbicide combination containing at least two herbicides and their use for controlling unwanted vegetation.
• Certain herbicidally active sulfonylureas are known from US Pat. No. 5,476,936.
• the effectiveness of these herbicides against harmful plants is at a high level, but generally depends on the application rate, the particular form of preparation, the harmful plants to be combated or the range of harmful plants, the climatic and soil conditions, etc.
• Another criterion is the duration of action or the rate of degradation of the herbicide. If necessary, changes in the sensitivity of harmful plants that may occur with extended use of the herbicides or geographically limited must also be taken into account. Loss of activity in individual plants can only be compensated for to a limited extent by the higher application rates of the herbicides, e.g. because the selectivity of the herbicides is reduced or there is no improvement in effectiveness even with a higher application rate.
