Abstract

Synergistic combinations are provided which are compatible with cultivated plants and which comprise herbicides selected from the group consisting of benzoylcyclohexanediones for use in rice crops Herbicidal combinations are provided comprising bensulfuron-methyl, benzobicyclon, bromobutide, cyhalofop-butyl, ethoxysulfuron, fenoxaprop-P-ethyl, fentrazamide, pyrazolynate, pyrimisulfan, sulcotrione, tefuryltrione, tembotrione and, if appropriate, isoxadifen-ethyl are described. These combinations exhibit an effect which is superior to that of the herbicides used individually.

What is claimed is: 
     
         1 . A herbicidal combination, comprising an effective amount of
 A) tefuryltrione or an agriculturally acceptable salt thereof (component A),   B) sulcotrione (component B), and   C) optionally, the safener isoxadifen-ethyl (component C).   
     
     
         2 . A herbicidal combination, comprising an effective amount of
 A) tembotrione or an agriculturally acceptable salt thereof (component A),   B) tefuryltrione and benzobicyclon (component B), and   C) the safener isoxadifen-ethyl (component C).   
     
     
         3 . A herbicidal combination as claimed in  claim 1 , wherein component C is present. 
     
     
         4 . A herbicidal combination as claimed in  claim 1 , wherein the components A, B and C are present in a weight ratio of A:B:C, in which A and B are, in each case independently of one another, values of from 1 to 200 and C is from 0 to 200. 
     
     
         5 . A herbicidal combination as claimed in  claim 1 , wherein the components A, B, and C are present in a weight ratio of A:B:C, in which A and B, are in each case independently of one another, values of from 1 to 100 and C is a value of from 0 to 100. 
     
     
         6 . A herbicidal combination as claimed in  claim 2 , wherein the components A, B, and C are present in a weight ratio of A:B:C, in which A and B, are in each case independently of one another, values of from 1 to 100 and C is a value of from 1 to 100. 
     
     
         7 . A herbicidal combination as claimed in  claim 1 , which comprises from 0.2 to 95 percent by weight of active substances A, B and C, and further comprising from 99.8 to 5 percent by weight of formulation agents customary in plant protection. 
     
     
         8 . A herbicidal combination as claimed in  claim 2 , which comprises from 0.2 to 95 percent by weight of active substances A, B and, if appropriate, C, and further comprising from 99.8 to 5 percent by weight of formulation agents customary in plant protection. 
     
     
         9 . A method for combating undesirable plant growth, comprising applying at least one herbicidal combination according to  claim 1  to a harmful plant, a plant part thereof or an area under cultivation. 
     
     
         10 . A method for combating undesirable plant growth, comprising applying at least one herbicidal combination according to  claim 2  to a harmful plant, a plant part thereof, or an area under cultivation. 
     
     
         11 . A method according to  claim 9 , wherein the component A is applied in an application rate of from 10 to 1000 g of active substance per hectare (ai/ha), the component B is applied in an application rate of from 1 to 1000 g ai/ha and the component C is applied in an application rate of from 0 to 500 g ai/ha. 
     
     
         12 . A method according to  claim 9 , wherein the component A is applied in an application rate of from 10 to 500 g ai/ha, the component B is applied in an application rate of from 5 to 500 g ai/ha and the component C is applied in an application rate of from 0 to 400 g ai/ha. 
     
     
         13 . A method according to  claim 10 , wherein the component A is applied in an application rate of from 10 to 1000 g of active substance per hectare (ai/ha), the component B is applied in an application rate of from 1 to 1000 g ai/ha and the component C is applied in an application rate of from 1 to 500 g ai/ha. 
     
     
         14 . A method according to  claim 10 , wherein the component A is applied in an application rate of from 10 to 500 g ai/ha, the component B is applied in an application rate of from 5 to 500 g ai/ha and the component C is applied in an application rate of from 1 to 400 g ai/ha. 
     
     
         15 . A method according to  claim 9  to protect against unwanted plant growth occurring in rice crops. 
     
     
         16 . A method according to  claim 10  to protect against unwanted plant growth occurring in rice crops. 
     
     
         17 . A composition for controlling unwanted plant growth, comprising at least the herbicidal combination according to  claim 1 . 
     
     
         18 . A composition for controlling unwanted plant growth, comprising at least the herbicidal combination according to  claim 2 . 
     
     
         19 . A composition according to  claim 17 , additionally comprising a herbicide, insecticide, fungicide, safener, fertilizer, or adjuvant.
