TECHNICAL FIELD
The present invention relates to a novel haloalkyl sulfonanilide derivative or a salt thereof, and to a herbicide containing the compound as an active ingredient and a method of using the same.
BACKGROUND ART
Compounds in which haloalkyl sulfonanilide and heterocyclic ring are bound through a spacer such as an alkylene group to a nitrogen atom in the heterocyclic ring have been conventionally known as herbicide (for example, see <patcit id="pcit0001" dnum="JP2004107322A"><text>JP-A-2004-107322</text></patcit>).

The herbicides comprising, as an active ingredient, the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof of the present invention are useful for controlling annual, biennial and perennial weeds which grow in paddy fields, upland fields, orchards, swamps, etc., such as barnyard grass (<i>Echinochloa crus-qalli</i> Beauv., an annual gramineous grass which is an injurious weed of paddy fields), false pimpernel (<u style="single">Lindernia pyxidaria</u>, an annual scrophulariaceous weed which is an injurious weed of paddy fields), monochoria (<u style="single">Monochoria vaginalis,</u> an annual pontederiaceous weed which is an injurious weed of paddy fields), <u style="single">Monochoria korsakowii</u> (an annual pontederiaceous weed which is an injurious weed of paddy fields), ammannia <u style="single">(Ammannia multiflora</u> Roxb., an annual lythraceous weed which is an injurious weed of paddy fields), smallflower umbrella sedge <u style="single">(Cyperus difformis</u> L., an annual cyperaceous weed which is an injurious weed of paddy fields), needle spikerush <u style="single">(Eleocharis acicularis</u> Roem. et Schult, a perennial cyperaceous weed which is an injurious weed of paddy fields and which grows also in swamps and waterways), arrowhead (<u style="single">Sagittaria</u><u style="single">trifolia</u> L., an injurious perennial weed of Alismataceae family which grows in paddy fields, swamps and ditches), <u style="single">Sagittaria pygmaea</u> Miq., (an injurious perennial weed of Alismataceae family which grows in paddy fields, swamps and ditches), bulrush <u style="single">(Scirpus juncoides</u> Roxb. subsp. <u style="single">juncoides</u> Roxb., a perennial cyperaceous weed which grows in paddy fields, swamps and ditches), <u style="single">Eleocharis kuroguwai</u> (a perennial cyperaceous weed which grows in paddy fields, swamps and ditches), foxtail grass <u style="single">(Alopecurus aequalis</u> var. amurensis Ohwi, biennial gramineous grass which grows in upland fields and low swamps), wild oat (<u style="single">Avena fatua</u> L., a biennial gramineous grass which grows in plains, waste lands and upland fields), mugwort <u style="single">(Artemisia princeps</u> Pamp., a perennial composite weed which grows in cultivated and uncultivated fields and mountains), large crabgrass <u style="single">(Digitaria adscendens</u> Henr., an annual gramineous grass which is an injurious weed of upland fields and orchards), Gishigishi or Japanese dock <u style="single">(Rumex japonicus</u> Houtt., a perennial polygonaceous weed which grows in upland fields and roadsides), flatsedge (<u style="single">Cyperus iria</u> L., an annual cyperaceous weed which is an injurios weed of upland fields), slender amaranth (<u style="single">Amaranthus viridis</u> L., an annual weed of Amaranthaceae family which grows in vacant lands, roadsides and upland fields), cocklebur (<u style="single">Xanthium strumarium</u> L., an injurious annual composite weed which grows in upland fields), velvetleaf <u style="single">(Abutilon theophrasti</u> L., an injurious annual weed of Malvaceae family which grows in upland fields), jimsonweed (<u style="single">Datura</u><u style="single">stramonium</u> L., an annual solanaceous weed which is an injurious weed of upland fields), birdseye speedwell <u style="single">(Veronica persica</u> Poir., an injurious biennial weed of Scrophulariaceae family which grows in upland fields) and cleavers (<u style="single">Galium spurium</u> L., an injurious biennial weed of Rubiaceae family which grows in upland fields and orchards), etc. Particularly, herbicides comprising the haloalkyl sulfonanilide derivative or salt thereof of the present invention are useful for controlling weeds in paddy fields. The herbicides according to the present invention have a broad selectivity between paddy rice and injurious weeds of paddy fields, thus, the herbicides of the present invention exhibit an excellent effect as herbicides for controlling weeds in paddy fields.
Since the herbicides comprising, as an active ingredient, the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof exhibit an excellent controlling effect on weeds pre- or post-emergence, the characteristic physiological activities of the herbicides can be effectively manifested by treating fields with the herbicides before planting useful plants therein, or after planting useful plants therein (including the case in which useful plants are already planted as in orchards) but during the period from the initial stage of emergence of weeds to their growth stage. However, the application of the herbicides of the present invention is not restricted only to the modes mentioned above. The herbicides of the present invention can be applied to control not only weeds which grow in paddy fields but also weeds which grow in other places such as vestiges of mowing, temporarily non-cultivated paddy fields and upland fields, ridges between fields, agricultural pathways, waterways, lands constructed for pasture, graveyards, parks, roads, playgrounds, unoccupied areas around buildings, developed lands, railways, forests and the like. The treatment of target fields with the herbicides is most effective in economy when the treatment is made by the initial stage of emergence of weeds. However, the treatment is not restricted thereto and can be carried out even during the growth stage of weeds. For applying the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof as herbicides, they are generally formulated into a form convenient to use according to the procedure conventionally employed for preparing agricultural chemicals. That is, the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof is mixed with a suitable inert carrier and, as necessary, further with an adjuvant, in an appropriate ratio, and the mixture is made into a desired form of preparation, such as suspension, emulsion, emulsifiable concentrate, solution, wettable powder, water dispersible granule, granules, dust, tablets, jumbo, packs and the like, through dissolution, dispersion, suspension, mixing, impregnation, adsorption or adhesion.
The inert carriers usable in the present invention may be solid or liquid. Materials usable as the solid carriers include, for example, vegetable powders (e.g. soybean flour, cereal flour, wood flour, bark flour, saw dust, powdered tobacco stalks, powdered walnut shells, bran, powdered cellulose and extraction residues of vegetables), synthetic polymers such as powdered synthetic resins, clays (e.g. kaolin, bentonite and acid clay), talcs (e.g. talc and pyrophyllite), silica powders or flakes [e.g. diatomaceous earth, silica sand, mica and white carbon (i.e. highly dispersed silicic acid, also called finely divided hydrated silica or hydrated silicic acid)], activated carbon, natural mineral materials (e.g. powdered sulfur, powdered pumice, attapulgite and zeolite), calcined diatomaceous earth, ground brick, fly ash, sand, plastic carriers (e.g. polyethylene, polypropylene and polyvinylidene chloride), inorganic mineral powders (e.g. calcium carbonate powder, calcium phosphate powder, etc.), chemical fertilizers (e.g. ammonium sulfate, ammonium phosphate, ammonium nitrate, urea, and ammonium chloride) and compost. These materials can be used alone or in combination of two or more. Materials usable as the liquid carriers are selected not only from those which have solvency by themselves but also from those which have no solvency but capable of dispersing the active ingredient compound with the aid of adjuvants. Typical examples of the liquid carriers, which can be used alone or in combination of two or more, are water, alcohols (e.g. methanol, ethanol, isopropanol, butanol and ethylene glycol), ketones (e.g. acetone, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone and cyclohexanone), ethers (e.g. ethyl ether, dioxane, Cellosolve, dipropyl ether and tetrahydrofuran), aliphatic hydrocarbons (e.g. kerosene and mineral oils), aromatic hydrocarbons (e.g. benzene, toluene, xylene, solvent naphtha and alkylnaphthalenes), halogenated hydrocarbons (e.g. dichloroethane, chloroform and carbon tetrachloride), esters (e.g. ethyl acetate, diisopropyl phthalate, dibutyl phthalate and dioctyl phthalate), amides (e.g. dimethylformamide, diethylformamide and dimethylacetamide), nitriles (e.g. acetonitrile), and dimethyl sulfoxide.
As the adjuvants, there can be mentioned the following typical adjuvants. They are used according to respective purpose. They may be used alone or in combination of two or more, or may not be used at all. For the purpose of emulsifying, dispersing, solubilizing and/or wetting the active ingredient compounds, there are used surface active agents, for example, polyoxyethylene alkyl ethers, polyoxyethylene alkylaryl ethers, polyoxyethylene higher fatty acid esters, polyoxyethylene resinates, polyoxyethylene sorbitan monolaurate, polyoxyethylene sorbitan monooleate, alkylarylsulfonates, naphthalenesulfonic acid condensation products, ligninsulfonates and higher alcohol sulfate esters. For the purpose of imparting stable dispersion, tackiness and/or bonding property to the active ingredient compounds, there may be used adjuvants such as casein, gelatin, starch, methyl cellulose, carboxymethyl cellulose, gum arabic, polyvinyl alcohol, turpentine, bran oil, bentonite and ligninsulfonates. For the purpose of improving the flow properties of solid herbicidal compositions, there may be used adjuvants such as waxes, stearates and alkyl phosphates. Adjuvants such as naphthalenesulfonic acid condensation products and polyphosphates may be used as peptizers in dispersible herbicidal compositions. Adjuvants such as silicone oils may be used as defoaming agent.
Although the content of the active ingredient compound may be varied as occasion demands and there is no specific limitation for the content, it may be 0.01 to 90% by weight generally. For example, for the preparation of a powdered or granulated product, the content is preferably 0.01 to 50% by weight, and more preferably 0.1 to 10% by weight. For the preparation of an emulsifiable concentrate, wettable powder or granulated wettable powder, the content is also suitably 0.01 to 90% by weight as well, and more suitably 0.01 to 60% by weight. For controlling various weeds or inhibiting their growth, the herbicides comprising, as an active ingredient, the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof are applied as such or after appropriately diluted with or suspended in water or other media, in an amount effective for controlling weeds or inhibiting their growth, to the foliage and stalks of the weeds or to soil in the area where the emergence or growth of the weeds is undesirable. The usable amount of herbicides comprising, as an active ingredient, the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof varies depending on various factors, for example, the purpose of application, the kinds of target weeds, the growth states of crops, the emergence tendency of weeds, weather, environmental conditions, the form of the herbicides used, the mode of application, the type or state of application site and the time of application. However, the amount is selected appropriately according to the purpose from the range of 0.1 g to 10 kg in terms of the amount of active ingredient compound per hectare. The herbicides containing, as an active ingredient, the haloalkyl sulfonanilide derivative represented by the formula (I) or salt thereof can be applied jointly with other herbicides for the purpose of expanding both the spectrum of controllable weeds and the period of time when effective application is possible or for the purpose of reducing the dosage.
Next, the present invention will be described particularly using examples, but the present invention is not limited to these.

Test Example 4. Low dosage test for rice paddy weeds
A 75 cm<sup>2</sup> plastic pot was filled with soil (clay loam) and planted seeds of bulrush which is a rice paddy weed. After covering the top with 75 cm<sup>3</sup> soil, the pot was filled with water so that the soil submerged under 5 cm depth of water and kept in a hot house. The test plants, at the one leaf stage, were treated with the solution of a formulation containing the compound of the present invention as an active ingredient at the predetermined effective dosage (300 g/ha as an active ingredient). The pots were kept in a hot house for 21 days after the treatment and the herbicidal efficacy was investigated and evaluated according to the standard in Test Example 1 by comparing with the untreated control. Results are shown in Table 7. Further, as a comparative compound, the compound No. 6-28 described in the <patcit id="pcit0004" dnum="JP2004107322A"><text>JP-A-2004-107322</text></patcit> was used.
Test Example 5. Selectivity between transplanted paddy rice plant and weeds
Phytotoxicity test for transplanted paddy rice plants was carried out, as in Test Example 3, by the treatment of 3000, 1000, 300 and 100 (g/ha of the active ingredient) dosage, and herbicidal test to weed post-emergence was carried out to Burlush seeded as in Test Example 2 treating at 300, 100, 30 and 10 (g/ha) dosage. The pots were kept in a hot house for 21 days after the treatment, and the phytotoxicity and the herbicidal efficacy was investigated and evaluated according to the standard in Test Example 1 by comparing with the untreated control. From these results, selective indices were calculated according to the following formula, and the selectivity between transplanted paddy rice plant and Bulrush was evaluated. Results are shown in Table 7. Further, as a comparative compound, the compound No. 6-28 described in the <patcit id="pcit0005" dnum="JP2004107322A"><text>JP-A-2004-107322</text></patcit> was used. <maths id="math0001" num=""><math display="block"><mi>Selectivity Index</mi><mo>=</mo><mfenced><mi>The highest dosage at which no phytotoxicity to paddy rice was seen</mi></mfenced><mo>/</mo><mfenced separators=""><mi>The lowest dosage at which effective level</mi><mspace width="1em" /><mn>4</mn><mspace width="1em" /><mi>was demonstrated</mi></mfenced></math><img file="EP1852425A1_D0020.tif" /></maths>
