           [0002]    The present invention relates to novel oxygen containing fused cyclic derivatives or their salts, a process for producing them, and their use as herbicides, plant growth regulators, desiccants or defoliants.  
           [0003]    2. Description of the Related Art  
           [0004]    JP 09301973 discloses the herbicidal utility of chromene derivatives, in which the phenyl ring of the described compounds was substituted with a hetero-ring such as uracil. Recently WO 01/10861 also disclosed chromene derivatives which have potent herbicidal activity in pre-emergence and post-emergence applications.  
           [0005]    EP 271170 and U.S. Pat. No. 4,881,967 described chroman derivatives, in which the phenyl ring of the described compounds was substituted with many kinds of hetero-rings including phthalamide and triazolinone. WO 02/24704 disclosed chroman derivatives having herbicidal properties with a hetero-ring such as tetrahydro-6-oxa-2,3a,8a-triaza-azulene-1,3-dione.  
           [0006]    Despite the broad coverage of these patents, the specific oxygen containing fused cyclic compounds of the formula I mentioned below are novel and can be used to effectively control a variety of broad or grassy leaf plant species.

         [0084]    Herbicidal Activity  
         [0085]    The compounds of the present invention exhibit excellent herbicidal effect when used as an active ingredient of a herbicide. The herbicide can be used for a wide range of applications, for example on croplands such as paddy fields, upland fields, orchards vineyards and mulberry fields, and non-crop lands such as forests, turf, right of way, roadsides, railroads, playgrounds and factory sites. The application method may be suitable selected for soil treatment application, foliar application and water application.  
         [0086]    The compounds of the present invention are capable of controlling noxious weeds including grass ( gramineae ) such as barnyardgrass ( Echinochloa crus - galli  L.), crabgrass ( Digitaria sanguinalis  L.), green foxtail ( Setaria viridis  L.), goosegrass ( Eleusine indica  L.), wild oat ( Avena fatua  L.), johnsongrass ( Sorghum halepense  L.), quackgrass ( Agropyron repens  L.), alexandergrass ( Brachiaria plantaginea ), paragrass ( Panicum purpurascens ), sprangletop ( Leptochloa chinensis ) and red sprangletop ( Leptochloa panicea ); sedges (Cyperaceae) such as rice flatsedge ( Cyperus iria  L.), purple nutsedge ( Cyperus rotundus  L.), japanese bulrush ( Scirpus juncoides ), flatsedge ( Cyperus serotinus ), smallflower umbrellaplant ( Cyperus difformis  L.), slender spikerush ( Eleocharis acicularis  L.), and water chestnut ( Eleocharis kuroguwai ); alismataceae such as japanese ribbon wapato ( Sagittaria pygmaea ), arrow-head ( Sagittaria trifolia  L.) and narrowleaf waterplantain ( Alisma canaliculatum ); pontederiaceae such as monochoria ( Monochoria vaginalis ) and monochoria species ( Monochoria korsakowii ); scrophulariaceae such as falsepimpemel ( Lindernia pyxidaria ) and dopatrium ( Dopatrium junceum ); lythraceae such as toothcup ( Rotala indica ) and red stem ( Ammannia multiflora ), and broadleaves such as redroot pigweed ( Amaranthus retroflexus  L.), velvetleaf ( Abutilon theophrasti ), morningglory ( Ipomoea hederacea  L.), lambsquaters ( Chenopodium album  L.), prickly sida ( Sida spinosa  L.), common purslane ( Portulaca oleracea  L.), slender amaranth ( Amaranthus viridis  L.), sicklepod ( Cassia obtusifolia  L.), black nightshade ( Solanum nigrum  L.), pale smartweed ( Polygonum lapathifolium  L.), common chcikweed ( Stellaria media  L.), common cocklebur ( Xanthium strumarium  L.), flexuous bittercress ( Cardamine flexuosa ), henbit ( Lamium amplexicaule  L.) and threeseeded copperleaf ( Acalypha australis  L.). Accordingly, it is useful for controlling noxious weeds non-selectively or selectively in the cultivation of a crop plant such as corn ( Zea mays  L.), soybean ( Glycine max  Merr.), cotton (Gossypium spp.), wheat (Triticum spp.), rice ( Oryza sativa  L.), barley ( Hordeum vulgare  L.), oats ( Avena sativa  L.), sorgo ( Sorghum bicolor  Moench), rape ( Brassica napus  L.,  Brassica campestris  L.), sunflower ( Helianthus annuus  L.), sugar beet ( Beta vulgaris  L.), sugar cane ( Saccharum officinarum  L.), japanese lawngrass ( Zoysia japonica  Steud), peanut ( Arachis hypogaea  L.) or flax ( Linum usitatissimum  L.). The compound of the present invention is particularly effective for selectively controlling noxious weeds in the cultivation of corn, wheat, rice, soybean or cotton, especially in the cultivation of corn, soybean, wheat and rice.  
         [0087]    For the use as herbicides, the active ingredients of this invention are formulated into herbicidal compositions by mixing herbicidal active amounts with inert ingredients known to the art to facilitate either the suspension, dissolution or emulsification of the active ingredient for the desired use. The type of formulation prepared recognizes the facts that formulation, crop and use pattern all can influence the activity and utility of active ingredient in a particular use. Thus for agricultural use the present herbicidal compounds may be formulated as water dispersible granules, granules, suspension concentrates, tablets, capsules, wettable powders, dusts, solutions, emulsifiable concentrates (EC), microemulsion, suspoemulsion, invert emulsion or other type of formulations, depending on the desired weed targets, crops and application methods. However, so long as it is suitable for the purpose of the present invention, it may be formulated into any type of formulation that is commonly used in this field.  
         [0088]    These herbicidal formulations may be applied to the target area (Where suppression of unwanted vegetation is the objective) as dusts, granules, tablets, capsules or water or solvent diluted sprays. These formulation may be contain as little as 0.1% to as much as 97% active ingredient by weight.  
         [0089]    Dusts are admixtures of the active ingredient with finely ground materials such as clays (some examples include kaolin and montmorillonite clays), talc, granite dust or other organic or inorganic solids which act as dispersants and carriers for the active ingredient; these finely ground materials have an average particle size of less than 50 microns. A typical dust formulation will contain 1% active ingredient and 99% carrier.  
         [0090]    Wettable powders are composed of finely ground particles which disperse rapidly in water or other spray carriers. Typical carriers include kaolin clays, fullers earth, silicas and other absorbent, wettable inorganic materials. Wettable powders can be prepared to contain from 0.1 to 90% active ingredient, depending on the desired use pattern and the absorbability of the carrier. Wettable powders typically contain wetting or dispersing agent to assist dispersion in water or other carriers.  
         [0091]    Water dispersible granules are granulated solids that freely disperse when mixed in water. This formulation typically consists of the active ingredient (0.1% to 95% active ingredient), a wetting agent (1 to 15% by weight), a dispersing agent (1 to 15% by weight) and an inert carrier (1 to 95% by weight). Water dispersible granules can be formed by mixing the ingredients intimately then adding a small amount of water on a rotating disc (said mechanism is commercially available) and collecting the agglomerated granules. Alternatively, the mixture of ingredients may be mixed with an optimal amount of liquid (water or other liquid) and passed through an extruder (said mechanism is commercially available) equipped with passages which allow for the formulation of small extruded granules. Alternatively, the mixture of ingredients can be granulated using a high speed mixer (said mechanism is commercially available) by adding a small amount of liquid and mixing at high speeds to affect agglomeration. Alternatively, the mixture of ingredient can be dispersed in water and dried by spraying the dispersion through a heated nozzle in a process known as spray drying (spray drying equipment is commercially available). After granulation the moisture content of granules is adjusted to an optimal level (generally less than 5%) and the product is sized to the desired mesh size.  
         [0092]    Granules are granulated solids that do not disperse readily in water, but instead maintain their physical structure when applied to the soil or water using a dry granule applicator or by hand. These granulated solids may be made of clay, vegetable material such as corn cob grids, agglomerated silicas or other agglomerated organic or inorganic materials or compounds such as calcium sulfate. The formulation typically consists of the active ingredient (1 to 20%) dispersed on or absorbed into the granule. The granule may be produced by intimately mixing the active ingredient with the granules with or without a sticking agent to facilitate adhesion of the active ingredient to the granule surface, or by dissolving the active ingredient in a solvent, spraying the dissolved active ingredient and solvent onto the granule then drying to remove the solvent. Granular formulations are useful where in-furrow or banded application is desired.  
         [0093]    Emulsifiable concentrates (EC) are homogeneous liquids composed of a solvent or mixture of solvent such as xylenes, heavy aromatic naphthas, isophorone or other proprietary commercial compositions derived from petroleum distillates, the active ingredient and an emulsifying agent or agents. For herbicidal use, the EC is added to water (or other spray carrier) and applied as a spray to the target area. The composition of an EC formulation can contain 0.1% to 95% active ingredient, 4 to 95% solvent or solvent mixture and 1 to 20% emulsifying agent or mixture of emulsifying agent.  
         [0094]    Suspension concentrate (also known as flowable) formulations are liquid formulations consisting of a finely ground suspension of the active ingredient in a carrier, typically water or a non-aqueous carrier such as an oil. Suspension concentrates typically contain the active ingredient (0.1 to 50% by weight), carrier, wetting agent, dispersing agent, anti-freeze, viscosity modifiers and pH modifiers. For application, suspension concentrates are typically diluted with water and sprayed on the target area or they are directly applied to flooded water in paddy field.  
         [0095]    Microemulsions are solutions consisting of the active ingredient (1 to 30%) dissolved in a surfactant or emulsifier, with additional solvents. Microemulsions are particularly useful when a low odor formulation is required such as in residential turfgrass applications.  
         [0096]    Suspoemulsions are combinations of two active ingredients. One active ingredient is made as a suspension concentrate (1 to 50% active ingredient) and the second active ingredient is made as an emulsifiable concentrate (0.1 to 20%). A reason for making this kind of formulation is the inability to make an EC formulation of the first ingredient due to poor solubility in organic solvents. The suspoemulsion formulation allows for the combination of the two active ingredients to be packaged in one container, thereby minimizing packaging waste and giving greater convenience to the product user.  
         [0097]    The herbicidal compounds of this invention may be formulated or applied with insecticides, fungicides, acaricides, nematicides, fertilizers, plant growth regulators or other agricultural chemicals. Certain tank mix additives, such as spreader stickers, penetration aids, wetting agents, surfactants, emulsifiers, humectants and UV protectants may be added in amount of 0.01% to 5% to enhance the biological activity, stability, wetting, spreading on foliage or uptake of active ingredients on the target area or to improve the suspensibility, dispersion, redispersion, emulsifiability, UV stability or other physical or physico-chemical property of the active ingredient in the spray tank, spray system or target area.  
         [0098]    The dose of the herbicidal composition of the present invention can not generally be defined, since it may be vary depending upon the weather condition, the soil condition, the type of the formulation, the types of the weeds to controlled, season for application, etc. However, it is usually applied so that the compound of the present invention would be applied in an amount of from 0.5 to 5000 g/ha, preferably from 1 to 1000 g/ha, more preferably from 5 to 500 g/ha. The present invention covers such a method for controlling noxious weeds by application of such a herbicidal composition.  
         [0099]    The herbicidal compositions of the present invention may be used in admixture with or in combination with other agricultural chemicals, fertilizers, adjuvants, surfactants, emulsifiers, oils, polymers and phytotoxicity-reducing agent such as herbicide safeners. In such a case, they may exhibit even better effects or activities. As other agricultural chemicals, herbicides, fungicides, antibiotics, plant hormones, plant growth regulators, insecticides or acaricides may, for example, be mentioned. Especially with herbicidal compositions having the compounds of the present invention used in admixture with or in combination with one or more active ingredients of other herbicides, it is possible to improve the herbicidal activities, the range of application time(s) and the range of applicable weed types. Further, the compounds of the present invention and an active ingredient of another herbicide may be separately formulated so they may be mixed for use at the time of application, or both may be formulated together. The present invention covers such herbicidal compositions.  
         [0100]    The blend ratio of the compounds of the present invention with the active ingredient of other herbicides can not generally be defined, since it varies depending on the time and method of application, weather conditions, soil type and type of formulation, etc. However one active ingredient of other herbicide may be incorporated usually in an amount of 0.001 to 10000 parts by weight, preferably from 0.01 to 1000 parts by weight, per one part by weight of compounds of present invention. Further, the total dose of all of the active ingredients is usually from 0.1 to 10000 g/ha, preferably from 0.2 to 5000 g/ha. The present invention covers a method for controlling noxious weeds by application of such herbicidal compositions.
