Description




FIELD OF THE INVENTION




The present invention relates to novel oxazole derivatives, process for producing said oxazole derivatives, and herbicides comprising said derivative(s) as the active ingredient(s) thereof.




BACKGROUND ART




In cultivation of agricultural and horticultural crops, herbicides have been used for weed control for which enormous labours have been required. However, such herbicides have often caused phytotoxicity on crops, have remained as residues in the environment and have been therefore a cause of environmental pollution. From such reasons, a development of herbicides, which can give firm herbicidal effectiveness with a lower dose and can be used without a problem of phytotoxicity, environmental residue and environmental pollution, has been required intensively.




Pyrimidyloxy-substituted salicylic acids similar to the compounds of the present invention and the sulfur homologs thereof are disclosed in Japanese Patent laid-open Nos. Sho 59-59669, Sho 62-174059, Hei 3-232884, Hei 4-77487, etc., however, there is no compound which has a satisfactory herbicidal-effect and a selectivity to crop plants.




In Japanese patent laid-open No. Hei 5-202038, it is disclosed that compounds represented by the following chemical formula;











where in r


1


and r


2


represent each independently lower alkyl or lower alkoxy; r


3

1


, y


2


and y


3


represent each independently H or the like; and b


1


represents CH or N, have a herbicidal effect.




It is an object of the present invention to provide herbicides which can be easily produced in an industrial scale, safe and excellent in herbicidal activity at a lower dose, and have excellent selectivity to various agricultural and horticultural crops.

In particular, the said compounds can demonstrate higher herbicidal activities on various weeds growing in upland crops, such as foxtails, an umbrella plant, a velvet-leaf and redroot Pigweed, by means of foliar application method, and wherein many compounds having a selectivity to maize, cereals, soybean, cotton, sunflower, etc. are contained.




In the compounds of the present invention, compounds which have a growth retarding activity against useful plants, such as field crops, vegetables,ornamentals and fruit trees, are contained as well.




Further, in the compounds of the present invention, compounds which have an excellent herbicidal activity against weeds grown in paddy rice fields, such as barnyardgrass,


Cyperus difformis, Sagittaria trifolia


, and


Scirpus juncoides


, and have a selectivity to rice plants, are also contained.




In addition, the compounds of the present invention can be applied for weed control in orchards, lawns, railways, vacant lands, etc.




Moreover, in the compounds of the present invention, compounds which have a plant growth regulating activity, a fungicidal activity, an insecticidal activity and an acaricidal activity, are also contained. Again, among the intermediates obtainable in the manufacturing of the compounds of the present invention, compounds having an herbicidal activity are also found.




Herbicides




The herbicides according to the present invention comprise one or more compounds of the present invention as the active ingredient(s). At practical application of the compounds of the present invention, the compounds can be applied alone without combining with other elements. Alternatively, the compounds of the present invent ion can be prepared into any of formulation types normally employed for plant protection chemicals, such as wettable powder, dust, emulsifiable concentrate, suspension and flowable formulation. As an additive or a filler to be used for such formulations, vegetable-origin powder, such as soybean powder and wheat flour, mineral fine powder, such as diatomaceous earth, apatite, gypsum, talc, bentonite, pyrophyllite and clay, and organic or inorganic materials, such as sodium benzoate, urea and Glauber's salt, can be used for a solid-type formulation. In case liquid-type formulations are required, a petroleum fraction, such as kerosine, xylene and solvent naphtha, cyclohexane, cyclohexanone, dimethylformamide, dimethylsulfoxide, alcohol, acetone, trichloroethylene, methylisobutyl ketone, mineral oil, vegetable oil, water, etc. can be used as a solvent. In order to assure uniform and stable physico-chemical properties of such formulations, a surface active agent may be used, if appropriate. As the surface active agent, any of nonionic, anionic, cationic and amphoteric surface active agents can be used, however, nonionic and/or anionic compounds are normally used. And, an appropriate quantity of such surface active agents to be used in the formulation is in a range of from 0.1 to 15% by weight, and preferably from 3 to 10% by weight.




As an appropriate nonionic surface active agent, a compound prepared by adding ethylene oxide by polymerization to a higher alcohol, such as lauryl alcohol, stearyl alcohol and oleyl alcohol; a compound prepared by adding ethylene oxide by polymerization to an alkyl phenol, such as isooctyl phenol and nonyl phenol; a compound prepared by adding ethylene oxide by polymerization to an alkyl naphthol, such as butyl naphthol and octyl naphthol; a compound prepared by adding ethylene oxide by polymerization to a higher alcohol, such as palmitic acid, stearic acid and oleic acid; a higher aliphatic acid ester of polyhydric alcohol, such as sorbitan, and a compound prepared by adding ethylene oxide by polymerization to said higher aliphatic acid ester; a compound prepared by addition polymerization of ethylene oxide and propylene oxide, are given for examples.




As an appropriate anionic surface active agent, an alkyl sulfate ester, such as sodium lauryl sulfate and amine salt of oleyl alcohol sulfate ester; an alkylsulfonate, such as sodium sulfosuccinate dioctyl ester and sodium 2-ethylhexenesulfonate; and an allyl sulfonate, such as sodium isopropylnaphthalene sulfonate, sodium methylenebisnaphthalene sulfonate, sodium lignin sulfonate and sodium dodecylbenzene sulfonate, are given for example.




The content of an active ingredient in the herbicide according to the present invention can differ depending upon formulation types as described above. For example, the content can be in a range of from 5 to 90%, and preferably from 10 to 85%, for a wettable powder formulation; from 3 to 70%, and preferably from 5 to 30%, for an emulsifiable concentrate formulation; and from 0.01 to 30%, and preferably from 0.05 to 10%, for a granular formulation.




The wettable powder and the emulsifiable concentrate obtained as described above can be applied in a form of suspension or emulsion after diluting them with appropriate volume of water. The granules obtained as described above can be directly applied to and/or incorporated into soil without dilution prior to or after germination of weeds. For practical application of the herbicide according to the present invention, an active ingredient in an appropriate amount more than 0.1 g/10 are contained therein could be applied.




The herbicide according to the present invention can be used by mixed with any of other known fungicides, insecticides, acaricides, herbicides, plant growth regulators, etc. In particular, it is possible to reduce the dose of the inventive herbicide to be applied in use by mixing with other herbicide. In this case, such mixing may provide an effect not only to reduce labours required for weeding but also to give higher herbicidal performance because of a synergistic action derived from herbicides mixed together. Mixing of the inventive herbicide with a plurality of other known herbicides is also possible.




For the examples of herbicides to be preferably associated with the inventive herbicide, carbamate-type and thiocarbamate-type herbicides, such as benthiocarb, molinate and dimepiperate; amide-type herbicides, such as butachlor, pretilachlor and mefenacet; diphenyl ether-type herbicides, such as chlomethoxynil and biphenox; triazine-type herbicides, such as atrazine and cyanazine; sulfonylurea-type herbicides, such as chlorsulfuron and sulfometuron-methyl; phenoxyalkane carboxylate-type herbicides, such as MCP and MCPB; phenoxyphenoxypropionic acid-type herbicides, such as diclofop-methyl; pyridyloxyphenoxypropionic acid-type herbicides, such as fluazifop-butyl; dinitroaniline-type herbicides, such as trifluralin and pendimethalin; urea-type herbicides, such as linuron and diuron; benzoylaminopropionic acid-type herbicides, such as benzoylprop-ethyl and flamprop-ethyl; imidazolinone-type herbicides, such as imazaquin; piperophos, daimuron, bentazone, difenzoquat, naproanilide, HW-52 (4-ethoxymethoxybenz-2,3-dichloroanilide), triazophenamide, quinclorac, and cyclohexanedione-type herbicides, such as sethoxydim and clethodim, are given. In addition, a vegetable oil and an oil concentrate may be added to a mixture of the inventive herbicide with one or more of the herbicides exemplified above.
