Abstract

1. Chimeric gene containing several herbicide tolerance genes, plant cell and plant which are tolerant to several herbicides. 2. The plant is tolerant to several herbicides at the same time, in particular to the inhibitors of HPPD and to those of EPSPS and/or to the dihalohydroxybenzonitriles. 3. Use for removing weeds from plants with several herbicides.

Claims (25)

1 - 21 . (canceled)

22 . Process for producing plants with multiple herbicide tolerance by transgenesis of the plants, comprising

inserting into several cells respectively one of the basic genes each containing regulatory elements necessary for its transcription in plants and a coding sequence encoding an enzyme conferring on plants tolerance to a herbicide, wherein one of the coding sequences encodes HPPD;

regenerating plants from said cells; and

crossing said plants in order to obtain plants with multiple tolerance.

23 . A process for the herbicidal treatment of plants according to claim 22 , comprising applying at least two herbicides to said plants of claim 22 .

24 . The process according to claim 23 , characterized in that three herbicides are applied.

25 . The process according to claim 23 , characterized in that one of the herbicides is an HPPD inhibitor.

26 . The process according to claim 23 , characterized in that both herbicides are applied simultaneously.

27 . The process according to claim 26 , characterized in that both herbicides are applied in the form of a single composition ready to use.

28 . The process according to claim 26 , characterized in that both herbicides are applied in the form of a freshly prepared mixture.

29 . The process according to claim 23 , characterized in that both herbicides are applied in succession.

30 . The process according to claim 25 , characterized in that the herbicide inhibiting HPPD is isoxaflutole.

31 . The process according to claim 25 , characterized in that the herbicide inhibiting HPPD is sulcotrione.

32 . The process according to claim 23 , characterized in that the herbicide belongs to the dihydroohydroxybenzonitrile family.

33 . The process according to claim 32 , characterized in that the herbicide is bromoxynil.

34 . The process according to claim 23 , characterized in that the herbicide inhibiting EPSPS is glyphosate.

35 . The process according to claim 22 , characterized in that the herbicide is ioxynil.

36 . The process according to claim 22 , wherein the second coding sequence encodes tolerance to glyphosate.

37 . The process according to claim 22 , wherein the second coding sequence encodes an EPSPS conferring tolerance to glyphosate.

38 . The process according to claim 22 , wherein the second coding sequence encodes glyphosate oxidoreductase.

39 . The process according to claim 22 , wherein the second coding sequence encodes tolerance to phosphinothricin.

40 . The process according to claim 22 wherein said second coding sequence encodes tolerance to a herbicide from the dihalohydroxybenzonitrile family.

41 . The process according to claim 22 wherein said herbicide is bromoxynil.

42 . The process according to claim 22 , wherein said herbicide is ioxynil.
