Abstract

Provided is a herbicidal composition containing ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate and one or more dicamba salts selected from the group consisting of dicamba diglycolamine salt and dicamba N,N-bis(3-aminopropyl)methylamine salt. The herbicidal composition can exert an excellent control efficacy on weeds.

Claims

1. A herbicidal composition comprising ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate and one or more dicamba salts selected from the group consisting of dicamba diglycolamine salt and dicamba N,N-bis(3-aminopropyl)methylamine salt, wherein a weight ratio of ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-3-yl)phenoxy]-2-pyridyloxy]acetate to the dicamba salt(s) is 1:

5 to 1;

100.

2. The herbicidal composition according to claim 1, wherein the dicamba salt is a dicamba diglycolamine salt.

3. The herbicidal composition according to claim 1, wherein the dicamba salt is a dicamba N,N-bis(3-aminopropyl)methylamine salt.

4. A method for controlling weeds, comprising a step of applying the herbicidal composition according to claim 1 to a place where weeds are growing or will grow.

5. The method according to claim 4, wherein the place where weeds are growing or will grow is a crop field.

6. The method according to claim 5, wherein the crop field is a field of soybeans, corn, or cotton.
