Herbicidal combinations comprising saflufenacil and epyrifenacil
The present invention relates to a combination or a composition comprising saflufenacil and epyrifenacil as well as to a method for weed control, which method comprises applying an effective amount of said herbicidal combination or composition to a non-crop area or to the cultivation area of a crop, where weeds grow or may grow. The invention also relates the use of the combination or of the composition comprising saflufenacil and epyrifenacil for weed control in a non-crop area or in the cultivation area of a crop.
1 . A herbicidal combination comprising
(A) saflufenacil and
(B) epyrifenacil
in a weight ratio [w/w] of (A):(B) from 8:1 to 1:8.
2 . The herbicidal combination of claim 1 , wherein the weight ratio [w/w] of (A):(B) is from 5:1 to 1:5.
3 . The herbicidal combination of claim 1 , wherein the weight ratio [w/w] of (A):(B) is 1:1.
4 . The herbicidal combination of claim 1 , further comprising an additional Protoporphyrinogen Oxidase (PPO) inhibitor as Component C.
5 . The herbicidal combination of claim 4 , wherein the further PPO inhibitor is trifludimoxazin.
6 . The herbicidal combination of claim 5 , wherein the weight ratio of saflufenacil:epyrifenacil:trifludimoxazin is 1:1:1.
7 . The herbicidal combination of claim 4 , wherein the further PPO inhibitor is 2-[2-[[3-chloro-6-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-5-fluoro-2-pyridinyl]oxy]phenoxy]acetic acid ethyl ester.
8 . The herbicidal combination of claim 7 , wherein the weight ratio of saflufenacil:epyrifenacil: 2-[2-[[3-chloro-6-[3,6-dihydro-3-methyl-2,6-dioxo-4-(trifluoromethyl)-1(2H)-pyrimidinyl]-5-fluoro-2-pyridinyl]oxy]phenoxy]acetic acid ethyl ester is 1:1:1.
9 . An agrochemical composition for weed control comprising (A) saflufenacil and (B) epyrifenacil in a weight ratio [w/w] of (A):(B) from 8:1 to 1:820:1 to 1:20, and one or more auxiliaries customary for herbicidal products or crop protection compositions.
10 . A method for controlling weeds, comprising applying an effective amount of a herbicidal combination to a non-crop area or to a cultivation area of a crop, where weeds grow or may grow,
the herbicidal combination comprising
(A) saflufenacil and
(B) epyrifenacil
in a weight ratio [w/w] of (A):(B) from 8:1 to 1:8.
11 . The method of claim 10 , wherein the application rate of (A) saflufenacil is from 2 to 100 g/ha and (B) epyrifenacil is from 2 to 100 g/ha.
12 . The method of claim 10 , wherein the application occurs in the cultivation area of a crop as a pre-planting burn-down treatment or pre-emergence treatment.
13 . The method of claim 10 , wherein application occurs in the cultivation area of PPO inhibitor tolerant crops as a post-emergence treatment.
14 . The method of claim 11 , wherein the application occurs in the cultivation area of a crop as a pre-planting burn-down treatment or pre-emergence treatment.
15 . The method of claim 11 , wherein application occurs in the cultivation area of PPO inhibitor tolerant crops as a post-emergence treatment.
