Herbicidal combinations comprising tefuryltrione for use in rice crops
View Patent ↗A description is given of herbicidal compositions comprising A) tefuryltrione and B) at least one additional herbicide. These compositions exhibit a superior action in comparison with the herbicides applied separately.
1. A synergistic herbicidal combination comprising an effective amount of
Component A) tefuryltrione and/or a salt thereof which is standard in agriculture and
Component B) at least one compound selected from the group consisting of the herbicides cyclosulfamuron, flucetosulfuron, orthosulfamuron, penoxsulam, pyroxasulfone, pyroxsulam, and
3-chloro-N-[(4,6-dimethoxypyrimidin-2-yl)carbamoyl]-1-methyl-4-(5-methyl-5,6-dihydro-1,4,2-dioxazin-3-yl)-1H-pyrazole-5-sulfonamide, wherein the weight ratio A:B of herbicides (A) and (B) lies in a range from 1:1 to 20:1.
2. A synergistic herbicidal combination as claimed in claim 1 , which comprises 0.1-99% by weight of herbicides (A) and (B) and from 99 to 0.1% by weight of at least one formulating agent standard in plant protection.
3. A process for combating undesirable plant growth, said process comprising applying a synergistic herbicidal combination as claimed in claim 1 , to a harmful plant, a plant part thereof and/or an area under cultivation.
4. A synergistic herbicidal composition for combating undesirable plant growth, said composition comprising a combination of the herbicides (A) and (B) being as defined in claim 1 .
5. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises cyclosulfamuron.
6. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises flucetosulfuron.
7. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises orthosulfamuron.
8. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises penoxsulam.
9. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises pyroxasulfone.
10. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises pyroxsulam.
11. A synergistic herbicidal synergistic combination as claimed in claim 1 , wherein component (B) comprises 3-chloro-N-[(4,6-dimethoxypyrimidin-2-yl)carbamoyl]-1-methyl-4-(5-methyl-5,6-dihydro-1,4,2-dioxazin-3-yl)-1H-pyrazole-5-sulfonamide.
