Abstract

Primarily, the present invention relates to the use of substances of the formula (I) as herbicides, in particular for controlling broad-leaved weeds and/or weed grasses in crops of useful plants and/or as plant growth regulators for influencing the growth of crops of useful plants. The invention furthermore relates to the novel herbicidal substances of the formulae (Ib) and (Ia). The present invention also relates to corresponding compositions comprising one or more of the herbicides of the formula (I) and further agrochemically active substances, and also to plant growth-regulating or herbicidal compositions comprising one or more of these compounds. Moreover, the present invention relates to processes for preparing the compounds of the formula (I).
