Description
Herbicldal preparations containing a-phenoxy al kanolc add ox1 me esters The present Invention Is concerned with herblcldal preparations / containing a-phenoxy-alkanolc add oxlme esters as active substances, and also with the use of such oxlme esters for controlling undeslred plant growth, especially In grass crops.
The combating of undeslred plant growth 1n grass crops cannot be carried out satisfactorily with the known herbicides, because they possess hardly any activity against millet species, for example Digltaria sangulnalis, Echinochloa crus galll and Setarla faberii. These species of millet constitute a group of annual Phanerogamae which are so profusely distributed 1n many areas sown with grass crops that they jeopardise the cultivation of these crops or the use of the areas.
Accordingly, the problem hitherto has been to provide a herbicide which 1s capable of combating especially these species of millet, and this problem 1s solved by the present invention.
The present Invention provides a herblcldal preparation which comprises a compound of the general formula I 1n which and R2 each represent an aromatic, aliphatic, cycloallphatic or aral1phat1c group which groups may be unsubstltuted or optionally mono-, dl- or polysubstltuted by alkyl, halogen, alkoxy, halogenoalkyl or nitro groups and R^ may also represent a hydrogen atom or R1 and R2 together with the adjacent carbon atom represent a cycloallphatic hydrocarbon group which may optionally be mono-, d1- or polysubstltuted by alkyl, Rg represents a hydrogen atom or a lower alkyl group, jn represents 0, 1, 2 or 3, and each X represents a lower alkyl group, a lower alkoxy group, a halogeno-alkyl group or a halogen atom, in admixture or conjunction with a suitable carrier. The preparation may of course contain one or more compounds of the general formula I.
The present Invention also provides a method of protectlns living plant against weeds, wherein the area 1n the vicinity of a living plant 1s treated with a compound of the general formula I.
The present Invention further provides a method of protecting a crop area against weeds, wherein a crop area 1s treated with a compound of the general formula I.
As aromatic hydrocarbon groups represented by Rj and Rg there come Into consideration, for example, phenyl and naphthyl groups, as aliphatic hydrocarbon groups, for example, those containing 1 to 12 carbon atoms, for example methyl, ethyl, propyl, Isopropyl and butyl, as cycloallphatic hydrocarbon groups those containing 5 to 8 carbon atoms, for example cyclohexyl, and as arallphatlc hydrocarbon groups, for example, benzyl and phenyl-ethyl , and these groups may be substituted, for example, 1n the same or different ways by lower alkyl groups, for example methyl or ethyl, halogen atoms, for example chlorine or bromine, lower alkoxy groups, for example methoxy or ethoxy. As lower alkyl groups represented by R3 and as the other lower alkyl and lower alkoxy groups mentioned above there come Into consideration those containing 1 to 3 carbon atoms.
Rl and Rg together with the adjacent carbon atom may also form a cycloallphatic 5- to 8-membered ring, for example cyclohexyl dene and cyclo-octylldene, which may be mono-, d1- or poly-substituted by lower alkyl groups, for example methylβ and/or by othor groups, and which may also be nterrupted by —and/or 0 hotbro atoms.
When n represents 2 or 3, the substltuents represented by X may be the same or different.
The compounds used 1n accordance with the present Invention exhibit, surprisingly, a very good herblddal action agalest the above-mentioned species of millet, and are therefore especially suitable for combating these very resistant weeds. Especially distinguished 1n this connection are those compounds n which Rj and Rg 1n the above general φ formula I each represents an alkyl group containing 1 to 4 carbon atoms or a phenyl group that may be substituted by a nltro group , a methyl group or a chlorine atom, and Rj may (also represent a hydrogen atom, or R.| and to§ether with the adjacent carbon atom represent a cyclohexyl ldene or a trlmethyl -cyclohexenylldene group, Rj represents a hydrogen atom or a methyl group, n. represents 0 or an Integer from 1 to 3 and each X represents a methyl group or a halogen atom. The groups represented by Rj and R2 may be Identical or different.
The action of these compounds also extends to many other weeds , for example Slnapsls sp. , Solanum sp. . Medlcago sp. , Stellarla media.
Seneclo vulgaris . Matricaria obfonomllla, Lamlum amplexlcaule, Centaurea cyanus . Amaranthus retroflexus , Gal ium aparine , Chrysanthemum segetum, I omea purpurea dnd Polygonum Lapathl foil urn.
A further Important advantage of the compounds used In accordance with the present Invention Is their excel lent tolerabll l ty towards cultivated grasses, barley, wheat, oats , rye, maize, rice and potatoes, which are not Impaired by the treatments.
The rates of appl ication are, depending on the region of use and the nature of the plants, approximately 0,5 to 3 kg of active substance per hectare; when two or more compounds of the general formula I are used the range of approximately 0.5 to 3 kg refers of course to the total amount appl ied of these compounds.
The compounds used in accordance with the present Invention may be appl ied singly or a sr; a mixture of two or several active substances , and also 1n admixture with other plant protecting and pest combating agents. When it Is desired to widen the spectrum of action there may also be added other herbicides , 1n which case the selectivity 1s , of course , not always maintained. As herblddal ly active co-components for mixtures there are suitable, for example, active substances belonging to the groups of carboxyHc adds andjderlvatlves thereof, cachajQic as4d *Hpr1vat1vp¾ , dlphenyl ether derivatives, anil Ides, uracils, nltrlles and other k organic herbicides, for example malelc hydraz de, 3-am1no-l ,2,4-tr1-azole, N-(l ,l-d1methyl-2-propyl)-3,5-d1chlorobenzam1de, N.N-dl-frv-propyl )-2 ,6-dl n1 tro-4-tr f 1 uoro-methylan 1 ne , 4-am1 no-3 ,5 ,6- tr1 chloro-plcol nlc add and 1 ,1 '-dimethyl -4,4* -blpyridy 11 urn salts.
Depending on the purpose of use there may be added other substances, among which there are to be understood, for example, also phytotoxlc non-pytotoxtc additives, which may produce a synergistic ncrease 1n activity with herbicides, for example wetting agents, emulsifiers, solvents and oily additives.
The active compounds of the general formula I or mixtures thereof used 1n accordance with the present nvention are advantageously applied in the form of herblddal preparations, for example powders, spraying or dusting agents, granules, solutions, emulsions or suspensions, with the addition of liquid and/or solid vehicles or diluents and, 1f desired, of surface-active agents, for example wetting, adherent, emulsifying and/or dispersing agentss Suitable liquid carriers, are, for example, water, aliphatic and aromatic hydrocarbons, for example benzene, toluene, cyclohexanone and Isophorone and, also mineral oil fractions.
As solid carriers there are suitable mineral earths, for example tonsil, silica gel, talcum, kaolin, Attaclay, limestone and silicic acid, and vegetable products, for example meals.
As surface-active agents there may be mentioned, for example, calcium Hgn1rf ulphonate, polyoxyethylene octyl-phenyl ethers, naphthalene — sulphon c adds, pheno sul phonic adds, formaldehyde condensates, fatty alcohol sulphates and alkali metal and at (call ne earth metal salts of fatty adds.
The total amount of the active compound or compounds of the general formula I in the various herblddal preparations may vary within Bide limits. For example, the preparations may contain approximately 20to of liquid or solid carrier, and, If desired, also up to 20% by weigh y ^ of surface-active agent(s) .
The preparations may be applied In the usual manner, for example, wi th water as carrier 1n quantities of spray Hquor from 100 to 1 ,000 l itres per hectare. For the total destruction of weeds there may be applied directly quantities of spray Hquor exceeding 1 ,000 l itres per hectare that are sometimes used. It 1s also possible to use the agents In the so-called "ultra-low-volume method" . They may furthermore be appl ied 1n the form of mlcrogranules.
It Is also possible, for example, to apply the preparations ready for use by spraying or scattering them on the soil still free from weeds. By Incorporating the preparations In the soil their activity is generally increased.
