Synergistically active herbicidal agents that are compatible with cultivated plants and contain herbicides from the group of benzoylpyrazoles
View Patent ↗Synergistic and crop-plant-compatible herbicidal compositions comprising herbicides from the group of the benzoylpyrazoles Herbicidal compositions comprising A) a compound from the group of the benzoylpyrazoles, B) at least one further herbicide and C) optionally at least one safener are described as herbicides effective against monocotyledonous and/or dicotyledonous harmful plants. Compared to the herbicides applied individually, these compositions have superior activity, and at the same time they are highly compatible with crop plants.

6. The herbicidal composition of claim 2 , additionally comprising at least one fertilizer.
7. The herbicidal composition as claimed in claim 1 , in which the herbicide component (B) is imazamox-ammonium, iodosulfuron-methyl-sodium, mesosulfuron-methyl, or sethoxydim.
8. The herbicidal composition as claimed in claim 1 , in which the safener component (C) is mefenpyr-diethyl.
9. The herbicidal composition as claimed in claim 1 , in which the herbicide component (B) is imazamox-ammonium and the safener component (C) is mefenpyr-diethyl.
10. The herbicidal composition as claimed in claim 1 , in which the herbicide component (B) is iodosulfuron-methyl-sodium and the safener component (C) is mefenpyr-diethyl.
11. The herbicidal composition as claimed in claim 1 , in which the herbicide component (B) is mesosulfuron-methyl and the safener component (C) is mefenpyr-diethyl.
12. The herbicidal composition as claimed in claim 1 , in which the herbicide component (B) is sethoxydim and the safener component (C) is mefenpyr-diethyl.
13. A herbicidal composition according to claim 1 , comprising an effective amount of
A) the herbicide pyrasulfotole of the formula (A) or an agriculturally customary salt thereof (component (A)),
B) at least one herbicide (component (B)) selected from the group consisting of aminopyralid, carfentrazone-ethyl, flucarbazone-sodium, florasulam, imazamox-ammonium, iodosulfuron-methyl-sodium, mesosulfuron-methyl, sethoxydim and pyroxsulam, and
C) an amount, acting as an antidote, of at least one safener (component (C)) selected from the group consisting of mefenpyr-diethyl, cloquintocet-mexyl and isoxadifen-ethyl,
wherein said composition comprises the components (A), (B) and (C) in a weight ratio of x:y:z, where x, y and z in each case independently of one another may assume values of from 1 to 200, with the provisos that the ratio of component (A) to component (B) ranges from 1:20 to 20:1 and the ratio of components (A)+(B) to component (C) ranges from 1:5 to 20:1.
14. The herbicidal composition as claimed in claim 13 , which comprises the components (A), (B) and (C) in a weight ratio of x:y:z, where x, y and z in each case independently of one another may assume values of from 1 to 50.
