Herbicidal compositions for tolerant or resistant rice crops
View Patent ↗Herbicide combinations (A)+(B), if appropriate in the presence of safeners, with an effective content of (A) broad-spectrum herbicides from the group (A1) glufosinate (salts) and related compounds (A2) glyphosate (salts) and related compounds such as sulfosate, (A3) imidazolinones such as imazethapyr, imazapyr, imazaquin, imazamox or their salts and (A4) herbicidal azoles from the group of the protoporphyrinogen oxidase inhibitors (PPO inhibitors) and (B) one or more herbicides from the group consisting of (B0) one or more structurally different herbicides from the abovementioned group (A) or (B1) foliar- and soil-acting herbicides effective against selectively in rice monocotyledonous and dicotyledonous harmful plants (residual action) or (B2) herbicides which are effective selectively in rice against dicotyledonous harmful plants and/or sedges, and/or (B3) foliar-acting herbicides which are effective selectively in rice against monocotyledonous harmful plants, and/or (B4) foliar- and soil-acting herbicides which are effective selectively in rice against monocotyledonous harmful plants, herbicides from several of groups (B0) to (B4) are suitable for controlling harmful plants in rice which consists of tolerant or resistant mutants or transgenic rice plants and the rice crops are tolerant to the herbicides (A) and (B), if appropriate in the presence of safeners, which are contained in the combination.
1. A herbicidal composition which comprises the combination of:
(A) glufosinate or salts thereof; and
(B) one or more herbicides selected from the group of compounds consisting of
(B1) foliar- and soil-acting herbicides which are effective selectively in rice against monocotyledonous and dicotyledonous harmful plants selected from the group consisting of molinate, anilofos, and oxadiazon; and
(B2) herbicides which are effective selectively in rice against dicotyledonous harmful plants and/or sedges selected from the group consisting of carfentrazone, carfentrazone-ethyl, and benfuresate; and
(B4) clefoxidim; and optionally, adjuvants or formulation auxiliaries conventionally used in crop protection.
2. The herbicidal composition of claim 1 which comprises the combination of (A) glufosinate or salts thereof and (B) carfentrazone-ethyl.
3. The herbicidal composition of claim 1 which comprises the combination of (A) glufosinate or salts thereof and (B) carfentrazone.
4. A method for controlling harmful plants in rice crops which comprises:
applying an effective amount of a herbicide combination to the plants, seed of the plants, or the area under cultivation;
wherein the herbicide combination comprises a synergistically effective amount of the composition of claim 1 .
5. The method of claim 4 ,
wherein the (B) herbicide is carfentrazone-ethyl.
6. The method of claim 4 ,
wherein the (B) herbicide is carfentrazone.

which comprises the combination of (A) glufosinate salt and molinate.
8. The herbicidal composition of claim 1 ,
which comprises the combination of (A) glufosinate salt and anilofos.
9. The herbicidal composition of claim 1 ,
which comprises the combination of (A) glufosinate salt and oxadiazon.
10. The herbicidal composition of claim 1 ,
which comprises the combination of (A) glufosinate salt and carfentrazone-ethyl.
11. The herbicidal composition of claim 1 ,
which comprises the combination of (A) glufosinate salt and clefoxidim.
