Description
i 149772
Opfindelsen angår hidtil ukendte 4H-3,l-benzoxazin-4-oner og -4-thioner, herbicider, der indeholder disse forbindelser som aktive stoffer, samt en fremgangsmåde til bekæmpelse af uønsket plantevækst med disse forbindelser.
5 Substituerede 4H-3,1-benzoxazin-4-oner er kendt som mel lemprodukter til syntese af farmakologisk aktive forbindelser (DE-OS 16 70 375, DE-OS 25 56 590). Desuden er det fra BE-PS 648 259 kendt, at halogensubstituerede 4H-3,l-benzoxazin-4-oner, der i 2-stillingen bærer en even-10 tuelt substitueret phenylgruppe, er herbicidt aktiv.
Det ville dog være ønskeligt at tilvejebringe nye herbicider af benzoxazintypen med forbedret herbicid aktivitet og forbedret forligelighed med kulturplanter i sammenligning med de ovenfor anførte, kendte herbicider.
15 Det er således opfindelsens formål at tilvejebringe nye benzoxazinder ivater, der har en bedre herbicid aktivitet og en bedre kulturplanteforligelighed end de kendte, som herbicider fungerende benzoxazinderivater.
Benzoxazinderivaterne ifølge opfindelsen, der er af den 20 i indledningen til krav 1 angivne art, er ejendommelige ved det i den kendetegnende del af krav 1 angivne.
Herbiciderne ifølge opfindelsen er ejendommelige ved det i den kendetegnende del af krav 5 angivne, og fremgangsmåden til bekæmpelse af uønsket plantevækst ifølge op-25 findelsen er ejendommelig ved det i den kendetegnende del af krav 6 angivne.
Det har overraskende vist sig, at benzoxazinderivaterne ifølge opfindelsen ved bedre forligelighed overfor en række af kulturplanter har bedre herbicid aktivitet end de 30 fra BE-PS 648259 kendte forbindelser.
I formel I betyder f.eks. fluor, chlor, brom, iod, ni- 2 tro eller methyl, R f.eks. fluor, chlor, brom, iod, tri-fluormethyl, trifluormethoxy eller chlordifluormethoxy.
149772 2
Foretrukne forbindelser med formel I er sådanne, i hvilke Y er oxygen, og R* er halogen, især fluor eller chlor, og 2 R er halogen, især fluor eller chlor, i m- eller p~ stilling på phenylringen.
5 Man kan fremstille 4H-3,l-benzoxazinderivaterne med formel I ved omsætning af en substitueret anthranilsyre med formel II
R1 Y
C-YH
kA (11)» NH2 hvori
R* og Y har de i krav 1 angivne betydninger, med mindst det 10 dobbelte molære overskud af et carboxylsyrehalogenid med formel III
R2

Velegnede indifferente opløsningsmidler til denne omsætning er carbonhydrider, såsom ligroin, benzin, toluen, pentan, hexan, cyclohexan, petroleumsether, halogencarbonliydrider, så-10 som methylenchlorid, chloroform, tetrachlorkulstof, 1,1- og 1,2-dichlorethan, 1,1,1- og 1,1,2-trichlorcthan, chlor-benzen, o-, m-, p-dichlorbenzen, o-, m-, p-chlortoluen, nitrocarbonhydrider, såsom nitrobenzen, nitroethan, o-, m-, p-chlornitrobenzen, nitriler, såsom acetonitril, bu-15 tyronitril, isobutyronitril, ethere, såsom diethylether, di-n-propylether, tetrahydrofuran, dioxan, estere, såsom aceteddikeester, ethylacetat eller isobutylacetat, eller amider, såsom formamid, methylformamid eller dimethyl-formamid.
20 Som syreacceptoren kan man anvende alle sædvanlige syrebin- demidler. Hertil hører fortrinsvis alkalimetalhydroxider, al-kalimetalcarbonater og tertiære organiske baser. Særligt veleg- 149772 5 net er f.eks. natriumhydroxid, natriumcarbonat, natrium-hydrogencarbonat, triethylamin, pyridin, trimethylamin, ot-, β-> /“-picolin, lutidin, Ν,Ν-dimethylanilin, N,N-di-methylcyclohexylamin, quinolin, tri-n-propylamin og tri-5 n-butylamin. Syrebindemidlet anvendes hensigtsmæssigt i ækvivalente mængder i forhold til carboxylsyrehalogenidet med formel III.
Som vandfjernende midler kan man anvende symmetriske og blandede carboxylsyreanhydrider, såsom eddikesyreanhydrid, 10 propionsyreanhydrid, smørsyreanhydrid, myresyreeddikesyre- anhydrid, myresyrepropionsyreanhydrid .eller eddikesyrepro-pionsyreanhydrid, desuden dicyclohexylcarbodiimid eller thionylchlorid. Cycliseringen gennemføres under tilsætning af den 1 til 10 gange molære mængde af vandsugende middel, 15 beregnet i forhold til carbonamid med formel IV.
Udgangsstofferne med formlerne II og III anvendes i omtrentligt støkiometrisk forhold, dvs. hensigtsmæssigt i et under- eller overskud på indtil 10?ί udgangsstof med formel III i forhold til udgangsstoffet med formel II.
20 Hensigtsmæssigt gennemfører man fremgangsmåden på den måde, at man via to tilførselsorganer lader carboxylsyrehalogenidet med formel III og den ækvivalente mængde af syre-acceptor ved en temperatur mellem 0 og 60°C løbe til en omtrentligt ækvivalent mængde af anthranilsyren med formel 25 II eller saltet deraf i et indifferent, organisk opløs ningsmiddel eller i vand. Derpå efterrører man i 15 minutter ved stuetemperatur. Reaktionsblandingen bliver derpå eventuelt koncentreret, gjort svagt sur i varmen med 5 n saltsyre, afkølet og frasuget (J.Org.Chem. 2, 396 (1964)), 30 hvorved der fremkommer en N-acyl-2-aminobenzoesyre. Denne kan derpå i nærværelse af den 5- til 10-dobbelte molære mængde af carboxylsyreanhydrid som vandsugende middel, f.eks. eddikesyreanhydrid, cycliseres ved omrøring - eventuelt, under afdestillation af den opståede eddikesyre - ved en 149772 6 temperatur mellem 30 og 130°C til den ønskede 4H-3,1-benzo-xazin. Med henblik på oparbejdning fjerner man herved overskydende vandsugende middel under reduceret tryk og om-krystalliserer eventuelt med henblik på rensning. I ste-5 - det for anthranilsyren kan man også bringe carboxylsyreha- logenidet til at foreligge. Hvis man anvender dicyclohexyl-carbodiimid eller thionylchlorid som vandsugende middel, kan cycliseringen gennemføres med 1 til 4 gange den molære mængde.
10 Med henblik på isolation af 4H-3,1-benzoxazinderivaterne med formel I fra reaktionsblandingen kan man behandle denne med vand, fortyndet alkali eller fortyndet syre til separation af biprodukter, såsom ikke omsat anthranilsyre, syrechlorid eller basehydrochlorid, tørre og derpå koncen-15 trere. Eventuelt kån slutprodukterne også renses ved omkry stallisation eller chromatografi.

Pulver-, udstrønings- og pudringsmidler kan fremstilles ved blanding eller fælles formaling af de aktive stoffer med et" fast bærestof.
15 Granulater, f.eks. omhyllings-, imprægnerings- og homogen granulater, kan fremstilles ved binding af de aktive stoffer til faste bærestoffer. Faste bærestoffer er mineraljorder, såsom silicagel, kiselsyrer, kiselgeler, silicater, talkum, kaolin, attaler, kalksten, kalk, kridt, bolus, løss, 20 ler, dolomit, diatoméjord, calcium- og magnesiumsulfat, magnesiumoxid, formalede formstoffer, gødningsmidler, såsom f.eks. ammoniumsulfat, ammoniumphosphat, ammoniumnitrat, urinstoffer og vegetabilske produkter, såsom kornmel, træbark-, træ- og nøddeskallemel, cellulosepulver og 25 andre faste bærestoffer.
Præparaterne indeholder mellem 0,1 og 95 vægt-?o aktiv .forbindelse, fortrinsvis mellem 0,5 og 90 vægt-% aktiv forbindelse.
Eksempler på præparater er: I. Man blander 90 vægtdele af forbindelsen i henhold til 30 eksempel 1 med 10 vægtdele N-methyl-oi-pyrrolidon og op når en opløsning, der er velegnet til anvendelse i form af meget små dråber.

Påvirkningen af forskellige repræsentanter for 4H-3,l-ben-zoxazinderivaterne med formel I på væksten af uønskede planter påvises ved drivhusforsøg:
Som kulturbeholdere tjente formstofurtepotter med et ind-15 hold på 300 cnr og lerholdigt sand med ca. 1,58 humus som substrat. Véd ris tilblandede man med henblik på behandlingen efter spiringen højere tørvandele for at sikre en bedre vækst. Frøene af forsøgsplanterne fladsåedes separat efter arter.
Ved behandlingen før spiringen påførte man de aktive stof-20 fer på jordoverfladen. De blev til dette formål suspende ret eller emulgeret i vand som fordelingsmedium og udsprøjtet ved hjælp af fint fordelende dyser. Ved denne applikationsmetode androg den anvendte mængde 3,0 kg aktivt stof/ha.
Efter påføringen af midlerne udsatte man beholderne for en 25 let regn for at bringe spiringen og væksten i gang. Derpå dækkede man beholderne med gennemsigtige formstofhætter, indtil planterne var vokset til. Afdækningen frembragte en regelmæssig spiring af forsøgsplanterne, dersom denne ikke blev påvirket i skadelig .retning af de aktive stof-30 fer.
Med henblik på behandlingen efter spiringen fremdrev man først forsøgsplanterne til en væksthøjde på mellem 3 og 149772 14 10 cm, i afhængighed af vækstformen, og behandlede dem derpå. Med henblik på behandlingen efter spiringen udvalgte man enten direkte såede og i de samme beholdere opvoksede planter, eller de blev først fremdrevet som kimplanter 5 og nogle dage før behandlingen omplantet i forsøgsbehol derne. Den mængde, man anvendte til behandlingen efter spiringen, varierede i afhængighed af aktivt stof. Den androg i det enkelte tilfælde 0,5 eller 1,0 kg aktivt stof/ha. Som sammenligningsmiddel anvendte man 2-phenyl-10 4H-3,l-benzoxazin-4-on (BE-PS 648 259) i en koncentration af 1,0 kg/ha. Man udelod en afdækning ved behandlingen efter spiringen. Forsøgsbeholderne stilledes ind i drivhuset , .hvorved man for termofile arter foretrak varmere områder (20 til 35°C) og for sådanne, der foretrak mere 15 moderate klimaer, foretrak 10 til 25°C. Forsøgsperioden strakte sig over 2 til 4 uger. I dette tidsrum plejede man planterne, og deres reaktion på de enkelte behandlinger blev bedømt. Man bedømte efter en skala fra 0 til 10.0. Derved betyder 0 ingen beskadigelse eller normal op-20 voksning, og 100 betyder ingen opvoksning af planterne eller fuldstændig ødelæggelse, i det mindste af de overjordiske dele.
Ved forsøgene prøvede man følgende planter:
Arachys hypogaea (jordnød), Avena sativa (havre), Cassia 25 tora, Centaurea cyanus (kornblomst), Chenopodium spp.
(gåsefod), Chrysanthemum spp. (okseøjearter), Datura stramonium (almindelig stikæble), Desmodium tortuosum,
Euphorbia geniculata (sydamerikansk ulvemælksart), Galium aparine (burre), Gossypium hirsutum (bomuld), Lud-30 \i/igia spp., Mercurialis annua, Sinapis alba (hvid sennep),
Solanum nigrum (sort natskygge), Oryza sativa (ris), Tri-ticum aestivum (hvede) og Zea mays (majs).
Ved undersøgelsen af den herbicide virkning ved anvendelse før spiringen i drivhus ved anvendte mængder på 3,0 kg 149772 15 aktivt stof/ha viste de nye forbindelser nr. .9, 16, 17 en god herbicid aktivitet ved god forligelighed med havre som repræsentant for kornsorterne.
Ved prøvningen for selektiv herbicid virkning ved anven-5 delse efter spiring i drivhus viste de aktive stoffer nr.
16 ved 1,0 kg/ha og nr. 17 ved 0,5 kg/ha en bedre herbicid aktivitet og en bedre kulturplanteforligelighed for bomuld end det kendte aktive stof A ved 1,0 kg aktivt stof/ha. De aktive stoffer nr. 1 og nr. 9 viser ved den 10 selektive ukrudtsbekæmpelse ved anvendelse efter opvoks- ningen i drivhus ligeledes ved 1,0 eller 0,5 kg aktivt stof/ha en udmærket god herbicid og selektiv virkning, der er bedre end for det kendte stof A.
Også ved prøvningen af selektiv herbicid virkning ved an-15 vendeisen efter spiringen i drivhus viser de aktive stof fer nr. 13 og 14 ved en anvendt mængde på 1,0 kg/ha en udmærket forligelighed med hvede og en udmærket virkning ved Solanum nigrum som repræsentant for ukrudtsarter , bedre end svarende til kendt teknik.
20 Ved prøvningen af de aktive stoffer nr. 2 og 12 ved 3,0 kg/ha ved anvendelse efter spiringen i drivhus udfoldede disse en betydelig herbicid aktivitet mod bredbladede u-krudtsarter, især Galium aparine, ved udmærket god for-ligelighed overfor korn, f.eks havre , og bedre end sva-25 rende til kendt teknik.
Hvis visse kulturplanter ved bladbehandling er noget følsomme overfor de aktive stoffer, kan man også anvende udbringningsteknikker, i forbindelse med hvilke de herbidi-de midler ved hjælp af sprøjteapparater ledes på en så-30 dan måde, at bladene af følsomme kulturplanter så vidt mu ligt ikke rammes, mens de rammer bladene af derunder voksende, uønskede planter eller den udækkede jordoverflade (post-directed, lay-by).
I betragtning· af den gode forligelighed og mangesidig-35 heden af applikationsmetoderne kan de aktive forbindelser iføl- 149772 16 ge opfindelsen,og herbicide midler, der indeholder disse, desuden anvendes ved et yderligere stort antal af kulturplanter til fjernelse af uønsket plantevækst. De anvendte mængder kan derved variere mellem 0,1 og 15 kg aktivt 5 stof/ha og derover, fortrinsvis mellem 0,5 og 3,5 kg ak tivt stof/ha. De retter sig efter det i ethvert tilfælde foreliggende bekæmpelsesobjekt, det vækststadium, på hvilket de uønskede planter befinder sig, og årstiden.

Det er nyttigt at udbringe midlerne ifølge opfindelsen alene eller i kombination med andre herbicider, men også blandet med yderligere plantebeskyttelsesmidler, f. eks. med midler til bekæmpelse af skadelige organismer el-10 ler phytapatogene svampe eller bakterier. Af interesse er desuden blandbarheden med mineralsaltopløsninger, der anvendes til ophævelse af ernærings- eller sporgrundstof-mangler.
Med henblik på aktivering af den herbicide virkning kan 15 man også tilsætte adhæsionsmidler samt ikke-phytotoxiske olier og oliekoncentrater.
De aktive stoffer ifølge opfindelsen nr. 1, 2, 3, 9, 13, 14, 15, 16 og 17 samt de kendte aktive stoffer med formlen 'b:W' i 34 149772
