Compounds of the formula I ##STR1## where R.sup.1 to R.sup.9 are as defined in claim 1 are known as herbicides. When these compounds are applied in traditionally used amounts, this often results in damage to crop plants in the crops, when it is desired to achieve sufficient action against weeds typically occurring therein. However, according to the invention it is possible to reduce the application rates to 0.001 to 0.5 kg of a.i./ha in rice growing, and the action obtained against important harmful plants in rice from the species Sagittaria, Cyperus and Scirpus Eleocharis is nevertheless sufficient.
A method of selectively controlling undesirable vegetation in corn by applying an herbicidally effective amount of 2-(2'-nitro-4'-trifluoromethylbenzoyl)- 1,3-cyclohexanedione to the locus of such vegetation.
A method of selectively controlling undesirable vegetation in corn by applying an herbicidally effective amount of 2-(2'-nitro-4'-methylsulfonylbenzoyl)-1,3-cyclohexanedione to the locus of such vegetation.
Benzoylcyclohexanedione derivatives of the formula (I) and their use as herbicides are described. ##STR1## In this formula (I), R.sup.1, R.sup.3, and R.sup.4 are various radicals, L--(R.sup.2).sub.n is haloalkyl, and n is 0 to 2.
The invention relates to novel thioether derivatives of substituted benzoyl bicycloalkane diones, their use as herbicides and agricultural compositions comprising the same.
