The combination of the novel herbicidal composition and the method of controlling the weed used. [Prior Art] φ In the agricultural field, for the improvement of productivity and labor saving, herbicides have been used since the early days. So far, various herbicides have been developed in response to the types of cultivated crops and weeds removed. In the case of this herbicide, it has no adverse effect with respect to cultivated plants, and is as effective as possible with respect to most kinds of weeds; that is, it is preferred to have a broad spectrum of herbicidal. However, in recent years, after using the same kind of herbicide for a long time, the weeds which are resistant to being difficult to remove relative to the herbicide increase, and the environmental pollution becomes a social problem due to the large-scale use of the pesticide, and it is expected that φ These highly active weeds are effective and can exhibit sufficient effects as high active herbicides at low doses. ^ On the other hand, it is more desirable to control the deterioration of the soil caused by the different herbicides used in the growth period of each crop or weed, and to correspond to the irregular growth of weeds that have been used for a long time. A long-lasting herbicide that is good and can be used for a long time from the growth of weeds to the growth period. Further, in the case of herbicides, the use of 'weather conditions' such as temperature, presence or absence of wind, strong sunlight, etc.; soil conditions, -6 - (2) 200808182 such as soil composition, organic matter content, etc.; cultivation Conditions 'such as transplant depth, water depth, etc.; herbicide application conditions, such as uneven distribution, excessive dispersion, etc.; cause phytotoxicity to crops. It is expected that by such changes in conditions, there will be herbicides that do not cause phytotoxicity to crops. " On the other hand, the combination of the two compounds is modified to separate the shortcomings of the herbicide as a compound. For example, as a herbicide composition which is a mixture of a herbicide for rice and a well-known compound, it is used as a herbicide composition for improving the safety of a rice sulfonate aniline derivative which exhibits a broad spectrum of herbicidal activity in a paddy field (JP2000-28) 1 5 1 3A); when used alone, it has to be used at a high concentration, which has an adverse effect on rice, and is in 2-[(4,6-dimethoxypyrimidin-2-yl)hydroxymethyl]- 6-methoxymethyl-N-difluoromethyl sulfonyl aniline, combined with orthobencarb, bensulide, asulam, propanil, etc. as an active ingredient of a herbicide, to improve its disadvantages of herbicide composition (W02004/ 01 0784A1) and other proposals. φ However, these herbicide compositions do not fully satisfy all of the above-mentioned desired matters; further, the development of herbicide compositions exhibiting superior effects has become an important issue in the agricultural field. SUMMARY OF THE INVENTION The present invention provides a herbicidal composition which has the above-mentioned disadvantages of the herbicide, has a broad herbicidal spectrum, exhibits high activity relative to weeds, has excellent residual effect, and has high safety with respect to cultivated plants. for purpose. The work of the present invention, in order to achieve the above various expectations, the development of weeding (3) 200808182 agent, after intensive investigation and continuous research results, found in the general formula of the difluoromethyl sulfonyl anilide compound or its salt, The herbicidal composition contained as an active ingredient in combination with a specific compound having herbicidal properties can prevent and remove various undesired weeds over a long period of time in rice cultivation, dry farming, horticultural cultivation, and dwarf grass breeding. The present invention can be carried out based on the knowledge that it grows and shows high safety with respect to cultivated plants' and can exert this effect before and after germination. That is, the present invention provides a herbicidal composition comprising: (A) a compound (ingredient A) selected from the group consisting of a difluoromethanesulfonylanilide compound represented by the general formula (1) or a salt thereof, And (B) selected from pyraclonil, imazo sulfuron, esprocarb, metamifop, triaziflam, pyr azoxy fen, 2,4-D, etobenzanid, mesotrion, tefuryltrione and weed microbes

[13th edition such as "The Pesticide Manual", 2004 (issued by the British Crop Protection Council) and "AG CHEM New compound Review 2006" (AGRANOVA issued). However, the present invention is characterized in that pyraclonil, imazo sulfuron, esprocarb, metamifop, triaziflam, pyrazoxyfen, 2 5 4 -D, etobenzanid, mesotrion, and tefuryltrione are selected from the above-mentioned group, and are used in combination with component A. Further, the microorganism for weeding can be used in the same manner as these. By combining the above-mentioned component A and component B, the synergistic effect can be exerted; when used alone, the desired wide range of herbicidal spectrum can not be obtained, and the growth control effect of weeds over a long period of time and Adequate safety for the protection of cultivated plants. R1 in the compound of the general formula (I) of the component A of the present invention is a hydrogen atom, a linear or branched alkyl group having 1 to 6 carbon atoms or a linear or branched alkyl group having 2 to 6 carbon atoms. Alkoxy group. Alkyl group is methyl, ethyl, propyl, iso-9- 200808182 (5) propyl, butyl, isobutyl, sec-butyl, tert-butyl, pentyl, 1-methylbutyl, hexyl temple For better 5, ethyl is more suitable. The methoxy group is preferably methoxymethyl, methoxyethyl, ethoxyethyl '3-ethoxypropyl, 1-methyl-3-methoxybutyl, etc. Oxymethyl groups are more suitable. ^ Further, the difluoromethanesulfonyl anilide compound or its salt represented by the general formula (I) may also be selected from the group consisting of halosulfuron-methyl, oxadiazon, cumyluron, clomazone, penoxsulam, MCPA, cyclosulfamuron, azimsulfuron, ethoxy At least one compound of sulfuron, cinosulfuron, flucetosulfuron, pyrimibenzoxim or the like is used in combination. On the other hand, the component B is preferably selected from the group consisting of pyraclonil, imazosulfuron, esprocarb, metamifop, triaziflam, pyrazoxyfen, 2,4-d, etobenzanid, mesotrion, tefuryltrione and herbicidal microorganisms. By this combination with the component A, it exhibits a faster appearance than the herbicidal effect when used alone, and thus a high herbicidal effect or a broad herbicidal spectrum which cannot be predicted by the herbicidal effect when used alone can be obtained. However, when it is a compound other than the above-mentioned component B, for example, the herbicidal which is comparable to the above compound is displayed alone, and the synergistic effect is not obtained by combining with the component A. Further, a microorganism for weeding, such as Drechslera monoceras (plant MTB-951), can also be used in combination with component A. A good herbicidal effect can also be obtained by mixing these two or more types.
