2. Description of the Related Art In recent years, a large number of paddy field herbicides have been used for cultivating rice crops, and recently, one-shot treatment agents which are intended to complete weeding with one application have been developed and put into practical use. However, since many kinds of weeds are mixed in the paddy field, and the amount, timing and growth rate of each weed greatly differ depending on the type of weeds and the weather conditions, conventional herbicides have different growth stages. It is difficult to kill all weeds with a single application, and it is difficult to control the late weeds for a long time. Especially, the Nobies represented by Tainubie are the same grasses as paddy rice, so they are completely controlled. It's hard to do.
Therefore, it is desired to develop paddy field herbicides that can control major weeds in paddy fields accurately and for a long time with a single treatment at any time from the occurrence of weeds to the growing season with a smaller amount of active ingredient. .

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a herbicide for paddy fields, which can control major weeds in paddy fields with a small amount of active ingredient by a single treatment at any time from the time of emergence of weeds to the growing season. This is an issue.

[0004]

[Means for Solving the Problems] As a result of intensive studies for solving the above problems, the present inventors have found that 2-[(4
6-Dimethoxypyrimidin-2-yl) oxy] -6-
Methyl [1- (N-methoxyimino) ethyl] benzoate or methyl 2-[(4,6-dimethoxypyrimidin-2-yl) oxy] -6- [1- (N-ethoxyimino) ethyl] benzoate , 2-[(4,6-dimethoxypyrimidin-2-yl) carbamoylsulfamoylmethyl] benzoate or N-[(4,6-dimethoxypyrimidin-2-yl) aminocarbonyl] -1-methyl-4 -(2-Methyl-2H-tetrazol-5-yl)
-1H-pyrazole-5-sulfonamide and 2-chloro-2 ', 6'-diethyl-N- (2-propoxyethyl) acetanilide or 2- (2-benzothiazol-2-yloxy) -N-methylacetanilide The herbicidal composition of the present invention containing the above as an active ingredient can be used at any time from the time of emergence of weeds to the growing season, and can accurately and long-lived major weeds in paddy fields, especially Noubie typified by Taenia cinerea. The present invention has been completed by finding that a herbicide for paddy fields that can be effectively controlled for a period of time can be obtained.

That is, the present invention provides 2-[(4,6-dimethoxypyrimidin-2-yl) oxy] -6- [1- (N
-Methoxyimino) ethyl] methyl benzoate (hereinafter A1
Or 2-[(4,6-dimethoxypyrimidine-

-[(4,6-Dimethoxypyrimidin-2-yl) carbamoylsulfamoylmethyl] benzoate (hereinafter referred to as B1) or N-[(4,6-dimethoxypyrimidin-2-yl) aminocarbonyl] -1 -Methyl-4-
(2-Methyl-2H-tetrazol-5-yl) -1H
-Pyrazole-5-sulfonamide (hereinafter referred to as B2)
And 2-chloro-2 ', 6'-diethyl-N- (2-
Propoxyethyl) acetanilide (hereinafter referred to as C1)
Or 2- (2-benzothiazol-2-yloxy)-
A herbicidal composition comprising N-methylacetanilide (hereinafter referred to as C2) as an active ingredient.

A1 and A2, which are one of the active ingredients of the herbicidal composition of the present invention, are known compounds known as herbicides having an effect on Taenia cinerea and the like (JP-A-4-13407).
No. 3 specification). B1 (generic name, bensulfuron-methyl) and B2 are also known herbicides, and are known to have an effect on annual and perennial broadleaf weeds and Cyperaceae weeds (JP-A-57-112379). ,
JP-A-3-41007, specification). Further, C1 (generic name, pretilachlor) and C2 (generic name, mefenacet) are also known herbicides, both of which are known to have an effect on annual weeds including Taenia muscaria (Japanese Patent Publication No. 53-23379). Gazette specification and JP-A-54-154762 specification).

A1 and A, which are one of the active ingredients of the present invention
No. 2 has an effect on Laevis, etc., but at a low dose, no effect can be expected on Laminaria with advanced leaf age of 3 leaves or more. In addition, the herbicidal effect on annual and perennial broad-leaved weeds and Cyperaceae weeds is low, and it is necessary to apply at high doses in order to exert sufficient effect, but application of high doses poses a safety issue for paddy rice. . On the other hand, B1 and B2
Has an effect on annual and perennial broad-leaved weeds and Cyperaceae weeds, but it does not show a sufficient effect on Taenia muridae, and there is a problem in the safety of paddy rice at a dose sufficient for Taenubia. Both C1 and C2 are effective against annual weeds such as Taenia japonicum, but at low doses the effective grass species are limited and the effect cannot be expected to be sustained. The herbicidal effect of this is not always satisfactory.

As described above, there are cases where the herbicidal effect cannot be fully expected when the active ingredients of the present invention are used alone.
Even if the seeds are mixed and used, there are cases where the herbicidal effect is not sufficiently satisfactory in terms of the specific grass species typified by Taenia cinerea, suitable period of use, and sustainability of effects.

Therefore, when a mixed use of A1 or A2, B1 or B2, and C1 or C2 was examined, it was found that the main weeds of Tainubie and other paddy fields were more accurately and long-term effective than single or mixed use of two kinds. It has been found that it can be controlled and has high safety against paddy rice.

The mixing ratio of the herbicidal composition according to the present invention is
You can expect an excellent herbicidal effect in a wide mixing range, but usually
The A1 or A2 component 1 is mixed with the B1 or B2 component in a weight ratio of 0.1 to 10, preferably 0.3 to 5, more preferably 0.5 to 3 parts, and further mixed with the A1 or A2 component. The C1 or C2 component is mixed with 1 to 1 to 100, preferably 3 to 50, and more preferably 5 to 20 parts. Note that these components may use the A1 and A2 components, the B1 and B2 components, and the C1 and C2 components, respectively.

The herbicidal composition according to the present invention can be used in various treatment methods, but it is particularly preferably used in flooded soil. The application rate is 0.01 to 30 Kg / h with the mixture as an active ingredient.
a can be used, preferably 0.1 to 5 Kg / ha, and particularly preferably 0.5 to 2 Kg / ha. The herbicidal composition of the present invention can also be used in combination with one or more other herbicides, for example, diphenyl ether, triazine, urea, amide, carbamate type and the like. In particular, it is useful when used in combination with cimetrin, dimetamethrin and Daimlon. What
The herbicidal composition of the present invention may contain an insecticide, a bactericide, a growth regulator and a fertilizer in addition to the above components.

The herbicidal composition of the present invention comprises a carrier, a surfactant, a dispersant or an auxiliary agent, etc., which is added to the above-mentioned active ingredient by a conventional method, for example, granules, wettable powders, emulsions, fine granules, It is preferable to apply it after formulating into a powder or flowable. Suitable carriers here include, for example, talc, bentonite, clay, kaolin, diatomaceous earth, white carbon, vermiculite, slaked lime, silica sand, ammonium sulfate, solid carriers such as urea, liquids such as isopropyl alcohol, xylene, cyclohexanone, oil and water.
