The term "herbicide" as used herein means a compound that controls or modifies the growth of plants. The term "herbicidally effective amount" means the quantity of such a compound or combination of such compounds that is capable of producing a controlling or modifying effect on the growth of plants. Controlling or modifying effects include all deviation from natural development, for example: killing, retardation, leaf burn, albinism, dwarfing and the like. The term "plants" refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, foliage, and fruits. The term "locus" is intended to include soil, seeds, and seedlings, as well as established vegetation and includes not only areas where weeds may already be growing, but also areas where weeds have yet to emerge, and also to areas under cultivation with respect to crops of useful plants. "Areas under cultivation" include land on which the crop plants are already growing and land intended for cultivation with such crop plants. The term "weeds" as used herein means any undesired plant, and thus includes not only agronomically important weeds as described below, but also volunteer crop plants.
The compounds of the invention can be applied before or after planting of the crops, before weeds emerge (pre-emergence application) or after weeds emerge (post-emergence application), and are particularly effective when applied pre-emergence. Crops of useful plants in which the composition according to the invention can be used include, but are not limited to, perennial crops, such as citrus fruit, grapevines, nuts, oil palms, olives, pome fruit, stone fruit and rubber, and annual arable crops, such as cereals, for example barley and wheat, cotton, oilseed rape, maize, rice, soy beans, sugar beet, sugar cane, sunflowers, ornamentals, switchgrass, turf and vegetables, especially cereals, maize, rice and soy beans.
Crops are to be understood as also including those crops which have been rendered tolerant to herbicides or classes of herbicides (e.g. auxins or ALS-, EPSPS-, PPO- and HPPD-inhibitors) by conventional methods of breeding or by genetic engineering. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding is Clearfield® summer rape (canola). Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®, respectively.
Crops are also to be understood as being those which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and also Bt potatoes (resistant to Colorado beetle). Examples of Bt maize are the Bt 176 maize hybrids of NK® (Syngenta Seeds). The Bt toxin is a protein that is formed naturally by Bacillus thuringiensis soil bacteria. Examples of toxins, or transgenic plants able to synthesize such toxins, are described in EP-A-451 878, EP-A-374 753, WO 93/07278, WO 95/34656, WO 03/052073 and EP-A-427 529. Examples of transgenic plants comprising one or more genes that code for an insecticidal resistance and express one or more toxins are KnockOut® (maize), Yield Gard® (maize), NuCOTIN33B® (cotton), Bollgard® (cotton), NewLeaf® (potatoes), NatureGard® and Protexcta®. Plant crops or seed material thereof can be both resistant to herbicides and, at the same time, resistant to insect feeding ("stacked" transgenic events). For example, seed can have the ability to express an insecticidal Cry3 protein while at the same time being tolerant to glyphosate.
Crops are also to be understood as being those which are obtained by conventional methods of breeding or genetic engineering and contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavor). Any method of application to weeds/crop of useful plant, or locus thereof, which is routinely used in agriculture may be used, for example application by spray or broadcast method typically after suitable dilution of a compound of formula (1) (whether said compound is formulated and/or in combination with one or more further active ingredients and/or safeners, as described herein). At the time of formulation or spraying, the compounds of the present invention can also as necessary be used mixed with other types of herbicide, various insecticides, bactericides, plant growth regulators or synergists and the like.
In particular, by using them mixed with other herbicides, broadening of the weed- killing spectrum and higher weed-killing efficacy can be expected due to cost reduction through dosage decreases, and the synergistic action of the mixed agents. In that case, combinations with a plurality of known herbicides simultaneously are also possible. Specific examples of mixtures of compounds of formula (1) with other herbicides include (wherein "1" represents a compound of formula (1)): 1 + 2,4-D (including the choline salt and 2-ethylhexyl ester thereof), 1 + acetochlor, 1 + acifiuorfen-sodium, 1 + aclonifen, 1 + alachlor, 1 + alloxydim, 1 + alloxydim sodium, 1 + ametryn, 1 +

The mixing ratio of the compound of formula (1) to the mixing partner is preferably from 1 : 100 to 1000: 1.
Compounds of formula (1) may also be combined with herbicide safeners. As combinations with safeners, are preferred, for example, (wherein "1" represents a compound of formula (1)) 1+ AD-67, benoxacor , 1 + cloquintocet-mexyl , 1 + cyomerinil , 1 + dichlormid , 1 + dicyclonone , 1 + cyprosulfamide , 1 + diethorate , 1 + DKA-24, dymron , 1 + fenclorazole ethyl , 1 + fenclorim , 1 + HEXIM , 1 + flurazole , 1 + fluxofenim , 1 + furilazole , 1 + isoxadifen , 1 + isoxadifen ethyl , 1 + MCPA, 1 + mecoprop , 1 + mefenpyr , 1 + mefenpyr ethyl , 1 + mefenpyr diethyl , 1 + mephenate , 1 + MG-191, NA (naphthalic anhydride), 1 + OM (octamethylene diamine), 1 + oxabetrinil , 1 + PPG- 1292, 1 + R-29148, 1 + N-(2-methoxybenzoyl)-4-[(methylaminocarbonyl)amino]benzenesulfonamide and the like are mentioned.

Preferably the mixing ratio of compound of formula (1) to safener is from 100: 1 to 1 : 10, especially from 20: 1 to 1 : 1.
The mixtures can advantageously be used in the above-mentioned formulations (in which case "active ingredient" relates to the respective mixture of compound of formula (1) and any further active ingredient, in particular a further herbicide, with the safener).
It is possible that the safener and a compound of formula (1) and one or more additional herbicide(s), if any, are applied simultaneously. For example, the safener, a compound of formula (1) and one or more additional herbicide(s), if any, might be applied to the locus pre-emergence or might be applied to the crop post-emergence. It is also possible that the safener and a compound of formula (1) and one or more additional herbicide(s), if any, are applied sequentially. For example, the safener might be applied before sowing the seeds as a seed treatment and a compound of formula (1) and one or more additional herbicides, if any, might be applied to the locus pre-emergence or might be applied to the crop post-emergence.
When the compounds of the present invention are used as herbicides, they are usually mixed with a suitable solid carrier or liquid carrier, and moreover surfactants, penetrants, spreading agents, thickeners, antifreeze agents, binders, anticaking agents, disintegrants, stabilizing agents and the like are added as desired, and they can be put to use in
formulations of any type, such as wettable powders, emulsions, flowables, dry flowables, liquids, powders, granules or gels. Further, to save labour and increase safety, the aforesaid formulations of any type can be sealed into waterproof packages.
As solid carriers, for example natural mineral substances such as quartz, kaolinite, pyrophyllite, sericite, talc, bentonite, acidic clay, attapulgite, zeolite and diatomaceous earth, inorganic salts such as calcium carbonate, ammonium sulphate, sodium sulphate, potassium chloride, synthetic silicic acid and synthetic silicate salts are mentioned.
As liquid carriers, for example alcohols such as ethylene glycol, propylene glycol and isopropanol, aromatic hydrocarbons such as xylene, alkylbenzenes and alkylnaphth-alenes, ethers such as butyl cellosolve, ketones such as cyclohexanone, esters such as γ- butyrolactone, acid amides such as N-methylpyrrolidone and N-octylpyrrolidone, plant oils such as soya bean oil, rapeseed oil, cottonseed oil and castor oil, and water, are mentioned.
These solid and liquid carriers can be used alone or 2 or more can be used together.
As surfactants, for example nonionic surfactants such as polyoxy ethylene alkyl ethers, polyoxyethylene alkyl aryl ethers, polyoxyethylene styryl phenyl ethers, polyoxyethylene polyoxypropylene block copolymers, polyoxyethylene fatty acid esters, sorbitan fatty acid esters and polyoxyethylene sorbitan fatty acid esters, anionic surfactants such as alkyl sulphate salts, alkylbenzenesulphonate salts, lignin-sulphonate salts, alkylsulphosuccinate salts, naphthalenesulphonate salts, alkylnaphthalenesulphonate salts, naphthalenesulphonic acid formalin condensate salts, alkylnaphthalenesulphonic acid formalin condensate salts, polyoxyethylene alkyl aryl ether sulphate and phosphate salts, polyoxyethylene styryl phenyl ether sulphate and phosphate salts, polycarboxylic acid salts and polystyrenesulphonate salts, cationic surfactants such as alkylamine salts and quaternary alkylammonium salts and amphoteric surfactants such as amino acid types and betaine types are mentioned.
Athough there is no particular restriction as to the content of these surfactants, usually from 0.05 to 20 parts by weight per 100 parts by weight of the formulation of the present invention is preferable. Further, these surfactants can be used alone, or 2 or more can be used together. At the time of formulation or spraying, the compounds of the present invention can also as necessary be used mixed with other types of herbicide, various insecticides, bactericides, plant growth regulators or synergists and the like.
In particular, by using them mixed with other herbicides, broadening of the weed- killing spectrum and higher weed-killing efficacy can be expected due to cost reduction through dosage decreases, and the synergistic action of the mixed agents. During this, combinations with a plurality of known herbicides simultaneously are also possible.
The dosage of the compounds of the present invention may differ depending on the use location, time of use, method of use, crop grown and the like, but in general from 0.005 to about 50 kg as active substance weight per hectare (ha) is suitable.

Test Examples
Next, the usefulness of the compounds of the present invention as herbicides is specifically explained in the following test examples, but the present invention is not limited only to these.
Test Example 1
Test of herbicidal efficacy by pre-emergence treatment under flooded conditions
4 cm depth flooded conditions were created by introducing alluvial soil into 1/30000 are polystyrene cups then introducing water and mixing. After mixing and sowing seeds of barnyard grass, bulrush and oval-leafed pondweed in the aforesaid cups, 2.5 leaf stage rice seedlings were transplanted. On the day of planting, emulsions of compounds of the present invention prepared according to Compounding Example 2 were diluted with water to give the specified dosages, and applied to the water surface. The cups were placed in a
greenhouse at 25 to 30°C and the plants were grown, and 3 weeks after the pesticide treatment the herbicidal effect against each plant type was assessed according to the following assessment criteria. The results are shown in Table 7.
Assessment Criteria
5 % weed control 90% or more (practically complete withering)
4 % weed control 70% to 90% 3 % weed control 40% to 70%
2 % weed control 20% to 40%
1 % weed control 5% to 20%
0 % weed control less than 5% (practically no effect) Test Example 2 Test of herbicidal efficacy by growth stage treatment under flooded conditions
4 cm depth flooded conditions were created by introducing alluvial soil into 1/30000 are polystyrene cups then introducing water and mixing. Barnyard grass, bulrush and oval-leafed pondweed seeds were mixed and sown in the aforesaid cups, placed in a greenhouse at 25 to 30°C and the plants were grown. When the barnyard grass, bulrush and oval-leafed pondweed had reached the 1-2 leaf stage, emulsions of compounds of the present invention prepared according to Compounding Example 2 were diluted with water to give the specified dosages and applied to the water surface. 3 weeks after the pesticide treatment, the herbicidal effect against each plant type was assessed in accordance with the assessment criteria of Test Example 1. The results are shown in Table 8. Test Example 3
