Opfindelsen angår hidtil ukendte cyclohexan-1,3-dion-derivater samt herbicider, der indeholder disse forbindelser, og fremgangsmåde til bekæmpelse af ukrudt under anvendelse af forbindelserne.
5
Cyclohexandion-derivater med thienyl- eller furylsubsti-tution i 5-position med relativt ringe herbicid virkning er kendt (DE-AS 24 39 104).
10 Det har overraskende vist sig, at forbindelserne ifølge opfindelsen, der er ejendommelige ved det i den kendetegnende del af krav 1 angivne, på udmærket måde bekæmper uønskede planter fra græsfamilien og samtidigt i deres egenskab af selektive herbicider udviser en høj grad af 15 forligelighed, hvad angår bredbladede og andre kulturplanter, der ikke hører til græsfamilien.

Man gennemfører hensigtsmæssigt reaktionen i heterogen fase i et indifferent opløsningsmiddel ved temperaturer mellem 0 og 80°C i nærværelse af en base. Baser er f.eks. carbonater, hydrogencarbonater, aceta-5 ter, alkoholater, hydroxider eller oxider af alkali eller jordalkalimetaller, især af natrium og kalium samt magnesium og kalium. Desuden kan man også anvende organiske baser, såsom pyridin eller tertiære aminer.
10
Et til omsætningen særligt velegnet, defineret pH-in-terval strækker sig mellem pH 2 og pH 7, især mellem pH 4,5 og pH 5,5. Indstillingen af pH-området til omsætningen foregår med fordel ved tilsætning af aceta- 15 ter, f.eks. alkaliacetater, især natrium- eller kaliumacetat, eller blandinger deraf. Man anvender f.eks. alkaliacetater i mængder på mellem 0,5 og 2 mol, beregnet i forhold til ammoniumforbindelsen.
20 Som opløsningsmiddel er f.eks. methanol, ethanol, isopropanol, benzen, tetrahydrofuran, chloroform, acetonitril, dichlorethan, eddikesyreethylester, di-oxan eller dimethylsulfoxid velegnet.
25 Reaktionen er afsluttet efter nogle timers forløb, og reaktionsproduktet kan isoleres ved koncentrering af blandingen, tilsætning af vand og ekstraktion med et ikke-polært opløsningsmiddel samt afdestillation af opløsningsmidlet under reduceret tryk.
30 (b) Derudover kan fremstillingen af de omhandlede forbindelser også gennemføres ved omsætning af forbindel- 2 seme II med de tilsvarende aminer R -0NH2· 1 (c) Desuden kan fremstillingen af derivaterne også gen nemføres ved alkylering af oximerne med alkylerings-midler:

2 15 Eksempel herpå er dimethylsulfat, hvor R er methyl, og X1 er monomethylsulfat.
Man foretrækker fremgangsmåde (a).
20 Forbindelserne med formel II kan fremstilles ved acyle-ring af cyclohexan-l,3-dionerne III som beskrevet i Tetrahedron Letters 29, 2491 (1975). Forbindelserne III kan ligeledes foreligge i tautomere former.

og påfølgende cyclisering med malonsyreestere analogt med Organic Synthesis Coll., bind II, side 200. Også ved omsætning af aldehydet Y-Xn-CH=0 med malonsyre i henhold til Knoevenagel-DObner (se Org. Reaktions, bd. 15, side 5 204), forestring af den fremkomne syre samt cyclisering med aceteddikeester, på analog måde som beskrevet f.eks. i Chem. Ber. 96, side 2946, når man til mellemprodukterne med formel III.
10 Saltene af forbindelserne med formlen I er f.eks. alkalisaltene, især natrium- eller kaliumsaltene.
Natrium- og kaliumsaltene af forbindelserne med formlen I kan fremstilles ved behandling af disse forbindelser med 15 natriumhydroxid eller kaliumhydroxid i vandig opløsning eller i et organisk opløsningsmiddel, såsom methanol, ethanol eller acetone. Man kan også anvende alkalialkoho-later som baser. 1 2 3 4 5 6
Andre metalsalte, f.eks. mangan-, kobber-, zink, jern 2 eller bariumsalte kan fremstilles ud fra natriumsaltet 3 ved reaktion med det tilsvarende metalchlorid i vandig 4 opløsning. De følgende eksempler illustrerer fremstil 5 lingen af de nye cyclohexandioner med formlen I (vægtdele 6 forholder sig til volumendel som kg til liter).

bladede kulturplanter lader sig påvise ved drivhus- og frilandsforsøg. Derved kan også kulturplanter fra familien Gramineae dræbes eller beskadiges stærkt. Dette kan i praksis i fuldt omfang være ønsket, da også kulturplan-5 ter kan optræde som uønskede planter, når de spirer fra i jorden tilbageblivende frø i en anden kultur, såsom f.eks. spildbyg i vinterraps eller sorghum i sojabønne-marker.
10 Som dyrkningsbeholdere til forsøgene tjente plastblom- 3 sterurtepotter med et indhold på 300 cm og lerholdigt sand med ca. 1,5% humus som substrat. Ved soja tilblandede man noget tørvestrøelse for at sikre en bedre vækst.
Frøene af forsøgsplanterne blev bredsået hver for sig 15 efter arter.
Ved behandlingen før spiringen blev de aktive stoffer påført på jordoverfladen. De blev til dette formål suspenderet eller emulgeret i vand som fordelingsmiddel og blev 20 udsprøjtet ved hjælp af fint fordelende dyser. Ved denne applikationsmetode androg den anvendte mængde 3,0 kg aktivt stof/ha. Efter påførsien af midlerne udsatte man beholderne for en let regn for at bringe spiring og vækst i gang. Derpå tildækkede man beholderne med gennemsigtige 25 plasthætter, indtil planterne var vokset til. Tildæk ningen frembragte en regelmæssig spiring af forsøgsplanterne, hvis denne ikke blev påvirket på skadelig måde af de aktive stoffer. 1 2 3 4 5 6
Med henblik på behandling efter spiringen fremdrev man 2 planterne til en væksthøjde på mellem 3 og 15 cm i af 3 hængighed af vækstform. De anvendte mængder til behand 4 lingen efter spiringen varierede efter aktivt stof og 5 anvendelsesformål. De androg 0,125, 0,25, 0,5 og 1,0 kg 6 aktivt stof/ha.

Ved gennemførelsen af drivhusforsøgene holdt man varme-35 elskende arter i varmere omgivelser (20 til 35°C) og sådanne, der foretrak mere moderat klima, holdt man fortrinsvis ved 10 til 20°C. Forsøgsperioden strakte sig
DK 162226 B
22 over 2 til 4 uger. I dette tidsrum blev planterne tilset, og deres reaktion på de enkelte behandlinger blev bedømt.
Der bedømmes efter en skala fra 0 til 100. Her betyder 0 ingen beskadigelse eller normal spiring, og 100 betyder 5 ingen spiring eller fuldstændig ødelæggelse, i det mindste af de overjordiske skuddele.
Ved de supplerende markforsøg, der også skal omtales her, blev midlerne ligeledes udbragt på småparceller efter 10 spiringen, efter at de var emulgeret eller suspenderet i vand som fordelingsmedium. Man benyttede til dette formål en marksprøjte, der var monteret på en traktor. De anvendte mængder androg 0,25 kg aktivt stof/ha. Bekæmpelsesmålet var spildbyg i ung vinterraps.

Til påvisning af resultaterne anvendte man følgende forsøgsplanter:

Resultaterne viser, at forbindelserne med formlen I ved anvendelse efter spiringen er velegnede til bekæmpelse af uønskede planter af græsfamilien (Gramineae). Her kan det dreje sig om typiske ugræsarter, såsom f.eks. flyvehavre 5 (Avena fatua) eller om kulturplanter fra familien Gramineae, der på grund af at de vokser på et forkert voksested, må betragtes som uønskede planter (f.eks. majs i en sojabønnemark). Enkelte forbindelser bekæmper på den ene side uønskede græsser, mens de på den anden side ved 10 siden af deres gode selektivitet for bredbladede kulturer samtidigt udviser en stor grad af forligelighed med hvede, der i botanisk henseende også hører til græsfamilien.
15 Undersøgelsen af den herbicide virkning ved anvendelse efter spiring af 0,25 kg aktivt stof/ha af forbindelse nr. 20 frembragte over for ni eksemplificerende græsarter en gennemsnitlig bekæmpelsesværdi på 81%. Ved den samme anvendte mængde og den samme anvendelsesmetode opnåede 20 forbindelse nr. 24 en værdi på 74%. Herudover udviste forbindelse 87 ved anvendelse efter spiring med 0,06 kg/ha en bekæmpelse, der lå mellem 65% og 100% over for uønskede græsarter, medens der ikke observeredes beskadigelse overhovedet af biosprøjtede sukkerroer.
25
Det kendte sammenligningsmiddel A havde derimod ligeledes ved anvendelse efter spiring af 0,25 kg aktivt stof/ha mod de samme græsarter kun en gennemsnitlig virkning på 52%. Også de to yderligere sammenligningsmidler B og C 30 udviste kun en forholdsvis svag herbicid aktivitet.
Bredbladede kulturplanter, såsom bomuld (Gossypium hirsu-tum), soj a (Glycine max.), sukkerroer (beta vulgaris) og raps (Brassica napus) forblev ved disse behandlinger 35 fuldstændigt uden beskadigelser eller udviste kun ganske uvæsentlige vækstbeskadigelser. Resultater er således, at de nye forbindelser udviser et højt mål af selektivitet
DK 162226B
24 for dikotyle kulturer. Derudover bekæmpede nogle af de nye forbindelser, såsom f.eks. forbindelserne nr. 31 og 1 med en anvendt mængde på 0,25 kg aktivt stof/ha uønskede græsser, såsom agerrævehale og hirsearter og forholdt sig 5 derved samtidigt selektivt, hvad angår nyttegræsarten hvede.
Hvad den herbicide aktivitet angår, kan det anføres, at man i en række yderligere eksempler kunne påvise virk-10 ningen af de nye forbindelser mod plantearter af græsfamilien, f.eks. forbindelserne nr. 2, 10, 11, 19, 24 og 26.
Ved de beskrevne drivhusforsøg viste desuden forbindel-15 serne nr. 1, 4, 5, 8, 31, 32 og 37 ved anvendelse efter spiringen et forholdsvist godt bekæmpelsesresultat.
Ved frilandsforsøg blev ved anvendelse efter spiringen af 0,25 kg aktivt stof/ha af forbindelserne nr. 10, 11 og 26 20 spildbyg selektivt bekæmpet i raps.
Ved siden af virkningerne ved påførsel efter spiringen opnåede man også positive resultater ved anvendelse før spiring af de nye forbindelser i drivhus. Således virkede 25 ved 3,0 kg aktivt stof/ha ved denne anvendelsesmetode forbindelserne nr. 2, 5, 8, 10, 14, 19, 26, 32, 36, 37, 48, 49, 54, 55, 77 og 78 stærkt herbicide mod de græsagt ige, eksemplificerede planter havre, "Weidelgras" og hønsehirse. Ligeledes havde forbindelserne nr. 1, 3 og 4 30 ved anvendelse før spiringen af 3,0 kg aktivt stof/ha i drivhus en betydelig herbicid aktitivet mod disse netop anførte græsser.
I betragtning af den gode forligelighed kan herbiciderne 35 ifølge opfindelsen, der indeholder disse, desuden anvendes i et yderligere stort antal kulturplanter til fjernelse af uønsket plantevækst. De anvendte mængder kan til
DK 162226 B
25 dette formål variere mellem 0,1 og 15 kg/ha og derover.

Til forøgelse af virkningsspektret og til opnåelse af synergistiske virkninger kan de nye cyclohexan-1,3-dion-derivater udbringes sammenblandet med kendte cyclohexan- 1,3-dion-derivater og med talrige repræsentanter for 5 andre herbicide eller vækstregulerende grupper af aktive stoffer. Som blandingspartnere kommer f.eks. diaziner, 4 H-3,1-benzoxazinderivater, benzothiadiazoner, 2,6-di- nitroaniliner, N-phenylcarbamater, thiolcarbamater, halo-gencarboxylsyrer, triaziner, amider, urinstoffer, diphe-10 nylether, triazinoner, uraciler, benzofuranderivater, cyclohexan- 1,3 -dionder ivater og andre i betragtning.
Det er desuden nyttigt at udbringe de nye forbindelser alene eller i kombination med andre herbicider, og des-15 uden også blandet med yderligere plantebeskyttelsesmidler, f.eks. med midler til bekæmpelse af skadelige organismer eller phytopatogene svampe eller bakterier. Af interesse er yderligere blandbarheden med mineralsaltopløsninger, der anvendes til at afhjælpe nærings- eller spor-20 stofmangler. Man kan også tilsætte ikke-phytotoxiske oli er og oliekoncentrater med henblik på aktivering af den herbicide virkning.
