    C:NRPonblDCCRXS484L464_DOC-4/0U2013 Many herbicidal compositions have been developed and practically used. However, types of weeds to be controlled are also many, and their emergence extends over a long period. Accordingly, it is desired that a herbicidal composition be developed which has a wider herbicidal spectrum and which is highly active and has a long lasting effect. As a result of a research to solve such problems, the present inventors have found it possible to obtain a highly practical herbicidal composition by a combined use of (A) 2- (4, 6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl) -N,N dimethylnicotinamide or its salt and (B) N2-tert-butyl-6 chloro-N 4-ethyl-1,3,5-triazine-2,4-diamine or its salt, and thus have accomplished the present invention.

TECHNICAL FIELD The present invention relates to a herbicidal composition comprising (A) 2-(4,6-dimethoxypyrimidin-2 ylcarbamoylsulfamoyl) -N,N-dimethylnicotinamide or its salt (hereinafter referred to simply as compound A) and (B) N 2 _ tert-butyl-6-chloro-N 4 -ethyl-1,3,5-triazine-2,4-diamine or its salt (hereinafter referred to simply as compound B). BACKGROUND ART Patent Document 1 discloses compound A but does not disclose its combined use with compound B. Patent Document 1: EP0232067A DISCLOSURE OF THE INVENTION Many herbicidal compositions have been developed and practically used. However, types of weeds to be controlled are also many, and their emergence extends over a long period. Accordingly, it is desired that a herbicidal composition be developed which has a wider herbicidal spectrum and which is highly active and has a long lasting effect.
    C:NRPorTbDCCRXS4&41464_I.DOC-4/0112013 -2 The present inventors have conducted research and have found that it is now possible to obtain a highly practical herbicidal composition. Namely, the present invention provides a herbicidal composition comprising (A) compound A i.e. 2-(4,6 dimethoxypyrimidin-2-ylcarbamoylsulfamoyl) -N, N dimethylnicotinamide (common name: nicosulfuron) or its salt and (B) compound B i.e. N2-tert-butyl-6-chloro-N 4 -ethyl 1,3,5-triazine-2,4-diamine (common name: terbuthylazine) or its salt. In a further aspect the invention provides a herbicidal composition comprising (A) 2-(4,6-dimethoxypyrimidin-2 ylcarbamoylsulfamoyl) -N, N-dimethylnicotinamide or its salt and (B) N 2 -tert-butyl-6-chloro-N4 -ethyl-1,,3,5-triazine-2,4 diamine or its salt, wherein the mix ratio of (A) and (B) is such that (B) is from 0.5 to 1,000 parts by weight per 1 part by weight of (A). Further, the present invention provides a method for controlling undesired plants or inhibiting their growth, which comprises applying a herbicidally effective amount of the herbicidal composition to the undesired plants or to a place where they grow. Further, the present invention provides a method for controlling undesired plants or inhibiting their growth, which comprises applying herbicidally effective amounts of compounds A and B to the undesired plants or to a place where they grow.
    C'NRPOrtblDCCRXS41464_1.DOC-41012013 -3 Further, the present invention also provides a synergistic method for controlling undesired plants or inhibiting their growth which comprises applying a herbicidally effective amount of a synergistic herbicidal composition comprising: (A) 2- (4, 6-dimethoxypyrimidin-2-ylcarbamoylsulfamoyl) -N, N dimethylnicotinamide or its salt, and (B) N 2 -tert-butyl-6-chloro-N 4 -ethyl-1,3,5-triazine-2,4 diamine or its salt, said composition being prepared by mixing compound A and compound B, as active ingredients, with additives, and optionally another herbicidally active ingredient in addition to compound A and compound B, wherein the mix ratio of (A) and (B) is such that (B) is from 1 to 250 parts by weight per 1 part weight of (A), to the undesired plants or to a place where they grow. EFFECTS OF THE INVENTION The herbicidal composition of the present invention, i.e. the herbicidal composition comprising compounds A and B, is capable of controlling a wide range of weeds CANRPortbADCCRXS4H4L464_].DOC-4//2001 -4 emerging> in cropland and non-cropland; and it surprisingly presents a synergistic herbicidal effect i.e. a herbicidal effect higher than the mere addition of the respective herbicidal ef-fects of the active ingredients. With such a herbicidal composition of the present -. invention, not orily it can be applied at . -low dose as compared with a case where the respective active, ingredients are. applied individually, but, also the herbicidal spectrum will be enlarged,- and further the herbicidal effects- will last -over a long period of time. When the herbicidal. activity in. a -case where two active ingredients are combined, is larger than the simple sum of the 'respective herbicidal activities of the. two active ingredients (the expected .activity), it is called a- synergistic effect. The activity expected by' the combination of two active ingredients can be calculated as follows (Colby S.R., "Weed", vol. 15, p. 20-22, 1967) where a: growth inhibition rate when treated with x (g/a) of herbicide X, 8: growth inhibition rate when treated with y (g/a) of herbicide Y, E: growth inhibition rate expected when treated with x (g/a) of herbicide X and y (g/a) of herbicide Y. Namely, when the actual growth inhibition rate (observed value) is larger than the growth inhibition C:NRPonbDCCRXS4841464 I DOC-4/2013 -5 rate by the above calculation (expected.value),- the activity by the combination can be regarded as showing a synergistic effect. The herbicidal composition of the .present invention shows a synergistic effect when calculated by the above formula. BEST MODE FOR CARRYING OUT THE INVENTION. -The salt included in compound A ai- B may be any salt so long as it is Agriculturally acceptable, .and it may, for exathple, be an alkali metal salt such as a sodium salt or a potassium salt; an alkaline earth metal salt such as a magnesium- salt or a. calcium salt; an ammonium salt such as- a monomethylammonium salt, a dimethylammonium salt or a triethylammonium salt; an inorganic.acid salt such as a hydrochloride, a perchlorate, a sulfate or a nitrate; or an organic -acid salt such as an a'cetate or a.methanesulfonate. As compound A, compounds having different crystal forms may sometimes be- obtained depending upon the production conditions. The present invention includes all of such compounds, and it also includes compounds having such compounds hydrated. In the present invention, the mix ratio of compound A and compound B varies depending upon various conditions such as the formulation, weather conditions, the types and growth conditions of the plants to be controlled and can not generally be defined. However, for example, C:NRPostbiDCCRXS4841464_IDOC-4,Oi/20)3 -6 compo,und B is in an amount of' from.0 5 to 1000- parts by. weight, preferably fronm 0.5 to 60.d parts by weight,. more preferably from 0.5 to 500 parts by weight, particularly' preferably from 1 to' 250 parts by weight, per 1 part by weight of compound A. The,present invention includes the herbicidal composition having the above-mentioned mix ratio, and a method for controlling undesired plants or inhibiting their growth, which comprises applying a herbicidally ,effective ,amount of the herbicidal composition. In its application, the application to the, undesired plants or the application to a place where they grow (either before or after the' emergence of the undesired plants) may optionally be selected. The-application amount of the herbicidal'composition of the present invention can not generally be defined, since it varies depending upon various conditions such as the mix ratio of compound A and compound ,B, .the formulation, weather conditions, the types and growth conditions of the plants to be controlled. However, compound A is usually from 1 to 200 g/ha, preferably from 2.5 to 100 g/ha, and compound B is usually from 100 to 5,000 g/ha, preferably from 200 to 2,500 g/ha. And, the suitable total application amount of compounds A and B is usually from 101 to 5,200 g/ha, preferably from 202.5 to 2,600 g/ha. The present invention includes a method for C :NRPoblDCCRXS484L464 1. DOC-4/0L12013 -7 controlling 'undesired plants or inhibiting. their growth, 'which compri .ses applying compound A.'ad compound B -in the respectively above-mentioned application amounts or .applying them iri the. above-mentioned suitable total application amount .In the application, the application to- the undesired -plants or the application to a place where they grow(either before or after the -emergence of the undesired plants) may optionally be selected.

On 'the 21st' daysafter: the application, the state.of growth of velvetleaf was visually observed and- evaluated in the same manner as in the above Test Example 1. The results are shown in Table 3.
