Description

Herbicid middel som inneholder Herbicide containing

carbamoyloxyfenylcarbamater. carbamoyloxyphenyl carbamates.

Foreliggende oppfinnelse angår herbicide blandinger som inne- The present invention relates to herbicidal mixtures containing

holder minst to forbindelser av gruppen carbamoyloxyfenylcarbamater. holds at least two compounds of the group carbamoyloxyphenylcarbamates.

Herbicide blandinger med forskjellige virkestoffer anvendes Herbicide mixtures with different active ingredients are used

ofte. De tjener f.eks. det formål å tilinte-tgjore mere fullstendig et storre antall plantearter med en eneste behandling enn det er mulig ved anvendelse av enkeltkomponentene. De fleste herbicide blandinger utviser bare den virkning som enkeltforbindelsene ville oppvise ved anvendelse alene. En virkning som går ut over virkningen av enkeltkomponentene i slike, blandinger, er derimot temmelig sjelden og er på grunn av det idag manglende kjennskap til den-mekanisme som ligger til grunn for virkningen, ikke forutsebar. often. They serve e.g. the purpose of annihilating more completely a larger number of plant species with a single treatment than is possible when using the individual components. Most herbicidal mixtures only exhibit the effect that the individual compounds would exhibit when used alone. An effect that goes beyond the effect of the individual components in such mixtures, on the other hand, is rather rare and, due to the current lack of knowledge of the mechanism underlying the effect, cannot be predicted.

Carbamoyloxyfenylcarbamater med herbicid virkning er tidligere kjent (tyske offentliggjorelsesskrifter 1.567.151, 1.568.621 og 1.920.775). ' Carbamoyloxyphenyl carbamates with herbicidal action are previously known (German published documents 1,567,151, 1,568,621 and 1,920,775). '

hvor R-^ er en fenylgruppe som eventuelt er substituert med lavere alkyl, lavere alkoxy eller halogen, R2 -er hydrogen eller lavere alkyl, og R., er lavere alkyl, men disse kjente blandinger er mindre, selekt-ive enn foreliggende blandinger, se de efterfolgende sammenlignings-forsok. where R-1 is a phenyl group which is optionally substituted with lower alkyl, lower alkoxy or halogen, R 2 -is hydrogen or lower alkyl, and R 1 is lower alkyl, but these known mixtures are less selective than present mixtures, see the following comparison tests.

Det har nu vist seg at blandinger inneholdende minst to forbindelser av den generelle formel: It has now been found that mixtures containing at least two compounds of the general formula:

hvor R^ er en fenylgruppe som eventuelt er substituert med lavere alkyl, halogen eller trifluormethyl, og R2 er en alkylgruppe med 1-3 carbonatomer, oppviser en oket og mere selektiv herbicid virkning. where R 2 is a phenyl group which is optionally substituted with lower alkyl, halogen or trifluoromethyl, and R 2 is an alkyl group with 1-3 carbon atoms, exhibits a stronger and more selective herbicidal effect.

Blandingene ifolge oppfinnelsen viser ved anvendelse i post-emergensmetoder en herbicid virkning overfor uonskede planter som ikke kan oppnåes med de tilsvarende mengder av enkeltkomponentene. Foruten denne overraskende ugressvirkning oppviser blandingene for-delen ved hby selektivitet overfor kulturplanter, f.eks. beta-roer, som ellers reagerer omfintlig ved post-emergenssproytninger med herbicider. When used in post-emergence methods, the mixtures according to the invention show a herbicidal effect on unwanted plants which cannot be achieved with the corresponding amounts of the individual components. In addition to this surprising weeding effect, the mixtures exhibit the advantage of hby selectivity towards cultivated plants, e.g. beta beets, which otherwise react extensively to post-emergence spraying with herbicides.

Mengdeforholdet mellom enkeltkomponentene i blandingene kan variere og er i hvert tilfelle avhengig av det onskede bekjempelses-resultat,•av arten av de ugress som skal bekjempes resp. de ikke onskede planter,■alderen av ugresset, henholdsvis plantene, de frem-herskende klimatiske betingelser såvel som anvendelsesteknikken. The quantity ratio between the individual components in the mixtures can vary and is in each case dependent on the desired control result, • on the nature of the weeds to be controlled or the unwanted plants, the age of the weeds, respectively the plants, the prevailing climatic conditions as well as the application technique.

I alminnelighet kan blandingsforholdet for en tokomponent-blanding utgjore fra ca. k:l til ca. l:<*>f, fortrinnsvis fra 1:1 til 2:1 vektdeler, mens blandingsforholdet for en trekomponentblanding kan være omtrent lik, altså ca. 1:1:1. ;De foretrukne virkestoffmengder ved anvendelse av blandingene ;i nytteplantekulturer som sukkerroer og andre beta-roer, utgjor ca. 0,5 - ^ kg virkestoff/ha, som imidlertid kan overskrides i særlige tilfelle. ;Den herbicide virkning av blandingene kommer særlig for dagen ;i deres tilberedninger som emulsjoner. Dette gjelder særlig for blandingseffektene. ;Anvendelsen av blandingene skjer derfor fortrinnsvis som emulsjoner eller på en for herbicide midler ellers vanlig måte i form av andre preparater, f.eks. pulvere, stromidler, granulater, oppløs-ninger, emulsjoner eller suspensjoner, under tilsetning av flytende og/eller faste bærerstoffer henholdsvis fortynningsmidler, og eventuelt grenseflateakitive stoffer, som fukte-, hefte-, emugerings-og/eller dispergeringshjelpemidler, såvel som gjodningsmidler eller andre stoffer. ;Egnede flytende bærerstoffer er vann, mineraloljer eller ;andre organiske opplosningsmidler, som f.eks. xylen, cyclohexanol, cyclohexanon, isoforon, kloroform, carbontetraklorid, dimethylform-amid, dimethylsulfoxyd og andre. ;Som faste bærerstoffer kommer f.eks. kalk, kaolin, kritt, talkum, attaclay og andre leirer på tale. ;Som grenseflateaktive stoffer kommer f.eks. anionaktive, kat-ionaktive og ikke-ionogene produkter, som f.eks. ethoxylert iso-octylfenol, ethoxylert octylfenol, ethoxylert nonylfenol, alkyl-fenolpolyglyc:olether, tributylfenylpolyglycolether, alkylarylsulfon-ater, alkylarylpolyetheralkoholer, isotridecylalkohol, alkylsulfater, laaryl-ethersulfat, fettalkoholethylenoxydkondensater, ethylert ricinusolje, polyoxyethylenalkylether, ethoxylert polyoxypropylen, sorbitester og laurylalkohol-polyglycoletheracetal på tale. ;Også andre herbicider kan tilsettes hvorved et bredere virke-spektrum, henholdsvis en bkning av den herbicide effekt kan oppnåes. Selektiviteten opprettholdes imidlertid naturligvis ikke derved. ;Som videre tilsetninger kan f.eks. også anvendes ikke-fytotoks-iske tilsetninger, som kan gi en synergisk virkningsokning ved herbicider, som fuktemidler, emulgatorer, opplosningsmidler, olje-aktige tilsetninger og andre. ;Fremstillingen av disse preparater kan utfores på i og for seg kjent vis, f.eks. ved blandings- eller maleprosesser. Om onskes kan enkeltkomponentene også forst blandes kort for anvendelsen, som det f.eks. gjores i praksis ved den såkalte tankblandingsmetode. ;Betydelige fordeler er forbundet med anvendelsen av blandingene ifolge oppfinnelsen da der for å oppnå den samme eller overraskende nok endog bedre virkning mot mange ugress kreves mindre virkestoffmengder enn.ved anvendelsen av enkeltkomponentene. ;Bekjempelsen av ugress henholdsvis uonskede planter kan, derfor utfores med sikrere resultat, mindre fare og under den storst mulige skåning av kulturplantene, på okonomisk vis. ;I det folgende er oppfort noen carbamater som anvendes i blandingene ifolge oppfinnelsen, og som er i og for seg kjent, eller kan fremstilles ved i og for seg kjente fremgangsmåter. ;De ovennevnte carbamater har også alene herbicid virkning, mén den beskrevne virkningsokning inntrer først ved anvendelse av blandinger av dem. ;De folgende eksempler belyser oppfinnelsen. ;Eksempel 1 ;I drivhus ble de nedenfor anforte planter i post-emergensstadiet besproytet med en mengde på 1 kg virkestoff pr. ;hektar, emulgert i 500 1 vann pr. hektar, med de folgende blandinger og deres enkeltkomponenter: ;;Blanding av I med IV, blandingsforhold 1 : 1 ;Blanding av II og IV, blandingsforhold 1 : 2 ;Blanding av III og IV,blandingsforhold 1 : 1 ;lh dager efter behandlingen viste blandingene ovenfor ved de oppforte uonskede plantearter en tydelig bedre virkning enn enkeltkomponentene. Forlikeligheten med sukkerroer forble derved full- , stendig opprettholdt. ;;Eksempel 2 ;I drivhus ble de nedenfor anforte planter i post-emergensstadiet besprdytet med en påforingsmengde på 0,5 kg virkestoff pr-., hektar, emulgert i 500 1 vann pr. hektar, med de fbMgende blandinger ifolge oppfinnelsen og deres enkeltkomponenter: ;Blanding av I med II, blandingsforhold 1 : 1 ;Blanding av I med III, blandingsforhold 1 : 1 ;Blanding av II med III, blandingsforhold 1 : 1. ;l*f dager efter behandlingen viste ovenstående blandinger på de oppforte uonskede plantearter en tydelig bedre virkning enn enkeltkomponentene. Forlikeligheten for sukkerroer ble fullstendig opprettholdt. In general, the mixing ratio for a two-component mixture can be from approx. k:l to approx. l:<*>f, preferably from 1:1 to 2:1 parts by weight, while the mixing ratio for a three-component mixture can be approximately the same, i.e. approx. 1:1:1. The preferred quantities of active substances when using the mixtures in useful plant cultures such as sugar beet and other beta beets amount to approx. 0.5 - ^ kg of active substance/ha, which can, however, be exceeded in special cases. The herbicidal effect of the mixtures is particularly apparent in their preparations as emulsions. This applies in particular to the mixing effects. The mixtures are therefore preferably used as emulsions or in an otherwise usual manner for herbicidal agents in the form of other preparations, e.g. powders, flow agents, granules, solutions, emulsions or suspensions, with the addition of liquid and/or solid carriers or diluents, and possibly surfactants, such as wetting, binding, emulsifying and/or dispersing aids, as well as fertilizers or other substances. Suitable liquid carriers are water, mineral oils or other organic solvents, such as e.g. xylene, cyclohexanol, cyclohexanone, isophorone, chloroform, carbon tetrachloride, dimethylformamide, dimethylsulfoxide and others. As solid carrier substances, e.g. lime, kaolin, chalk, talc, attaclay and other clays in speech. ;As surfactants, e.g. anion-active, cation-ion-active and non-ionic products, such as e.g. ethoxylated iso-octylphenol, ethoxylated octylphenol, ethoxylated nonylphenol, alkyl phenol polyglyc:ol ether, tributyl phenyl polyglycol ether, alkyl aryl sulfonates, alkyl aryl polyether alcohols, isotridecyl alcohol, alkyl sulfates, laaryl ether sulfate, fatty alcohol ethylene oxide condensates, ethylated castor oil, polyoxyethylene alkyl ether, ethoxylated polyoxypropylene, sorbitol esters and lauryl alcohol polyglycol ether acetal in speech . ;Also other herbicides can be added, whereby a wider spectrum of action, or an increase in the herbicidal effect, can be achieved. However, the selectivity is naturally not maintained thereby. As further additions, e.g. non-phytotoxic additives are also used, which can give a synergistic increase in the effectiveness of herbicides, such as wetting agents, emulsifiers, solvents, oily additives and others. The production of these preparations can be carried out in a manner known per se, e.g. by mixing or grinding processes. If desired, the individual components can also first be mixed briefly before the application, as it e.g. is done in practice by the so-called tank mixing method. Considerable advantages are associated with the use of the mixtures according to the invention, since in order to achieve the same or, surprisingly, even better effect against many weeds, smaller amounts of active substance are required than with the use of the individual components. The fight against weeds or unwanted plants can therefore be carried out with more reliable results, less danger and with the greatest possible sparing of the cultivated plants, in an economical way. In the following, some carbamates are listed which are used in the mixtures according to the invention, and which are known in and of themselves, or can be produced by methods known in and of themselves. The above-mentioned carbamates also have a herbicidal effect on their own, but the described increase in effect only occurs when mixtures of them are used. The following examples illustrate the invention. ;Example 1 ;In a greenhouse, the plants listed below in the post-emergence stage were sprayed with an amount of 1 kg of active substance per ; hectare, emulsified in 500 1 water per hectares, with the following mixtures and their individual components: ;;Mixing of I with IV, mixing ratio 1 : 1 ;Mixing of II and IV, mixing ratio 1 : 2 ;Mixing of III and IV, mixing ratio 1 : 1 ;lh days after the treatment showed the above mixtures have a clearly better effect on the listed unwanted plant species than the individual components. Compatibility with sugar beet was thus fully, permanently maintained. Example 2 In a greenhouse, the plants listed below in the post-emergence stage were sprayed with an application amount of 0.5 kg active substance per hectare, emulsified in 500 1 water per hectares, with the following mixtures according to the invention and their individual components: ;Mixing of I with II, mixing ratio 1 : 1 ;Mixing of I with III, mixing ratio 1 : 1 ;Mixing of II with III, mixing ratio 1 : 1. ;l*f days after the treatment, the above mixtures showed a clearly better effect on the listed unwanted plant species than the individual components. Compatibility for sugar beet was fully maintained.
