Herbicidal composition

The present invention is directed to a method which enables the user to select a suitable soya variety as a subsequent crop to maize when weed control in that maize crop has been carried out using HPPD inhibitor herbicides in a manner that 'carry-over' damage to the soya crop is thereby avoided. The method includes the step of first selecting a 'reference soya' that exhibits a visually determinable phytotoxicity with respect to the HPPD inhibitor herbicide used to carry out weed control on the maize crop. Next, the phytotoxicity of various soya varieties is determined in relation to the reference soya variety in the form of a factor. This factor can be expressed, for example, in letters, numbers, symbols, colors or other visual or acoustic signals or in words. These soya varieties are then labeled with the factor and can be made accessible to the user. For example, the factor can be indicated on or inside the product packaging or in an accompanying leaflet.
