Description

DK 155272 BDK 155272 B

Den foreliggende opfindelse angår et fungicid, nærmere betegnet et fungicidpræparat som indeholder den fungicidt virksomme forbindelse prochloraz. Prochloraz, 1-[N-propyl-N- 2-(2,4,6-triklorfenoxy)-ætylkarbamoyl]-imidazol har vist sig 5 at have et bredt område af fungicid aktivitet som beskrevet i USA-patentskrifterne nr. 3.991.071 og 4.080.462.The present invention relates to a fungicide, more particularly a fungicide composition containing the fungicidal active compound prochloraz. Prochloraz, 1- [N-propyl-N-2- (2,4,6-trichlorophenoxy) -ethylcarbamoyl] -imidazole has been found to have a wide range of fungicidal activity as disclosed in U.S. Patent No. 3,991,071. and 4,080,462.

Det har nu vist sig at prochloraz kan blandes med carbendazim til tilvejebringelse af et præparat med særlig gunstig fungicid aktivitet.It has now been found that prochloraz can be mixed with carbendazime to provide a composition with particularly favorable fungicidal activity.

10 I overensstemmelse hermed angår den foreliggende op findelse et fungicidt præparat som er ejendommeligt ved at indeholde prochloraz (1-/N-propyl-N-2-(2,4,6-triklorfenoxy)-ætylkarbamoyl7-imidazol) med carbendazim(metylbenzimidazol- 2-ylkarbamat) i et indbyrdes mængdeforhold i området 1:4 til 15 25:1, fortrinsvis i området 1:1 til 10:1.Accordingly, the present invention relates to a fungicidal composition characterized by containing prochloraz (1- / N-propyl-N-2- (2,4,6-trichlorophenoxy) -ethylcarbamoyl7-imidazole) with carbendazim (methylbenzimidazole). 2-ylcarbamate) in a mutual ratio in the range of 1: 4 to 25: 1, preferably in the range of 1: 1 to 10: 1.

Præparatet af prochloraz og carbendazim har fungicid aktivitet, og den foreliggende opfindelse angår også en fremgangsmåde til bekæmpelse af svampesygdomme i.afgrøder i vækst, hvilken fremgangsmåde er ejendommelig ved at man til afgrøden 20 fører en effektiv mængde af et vandigt præparat fremstillet ved tilsætning af præparatet ifølge opfindelsen til vand.The composition of prochloraz and carbendazim has fungicidal activity, and the present invention also relates to a method for controlling fungal diseases in growing crops, which is characterized by introducing to the crop 20 an effective amount of an aqueous composition prepared by adding the composition. according to the invention for water.

Når man påfører et præparat ifølge opfindelsen på en kornafgrøde, bevirkes der bekæmpelse af talrige svampesygdomme såsom meldug (Erysiphe graminis) på hvede, byg, havre og rug 25 og andre bladsygdomme såsom bladpletsyge som avneplet (Septoria nodorum), stråleplet (Rhyncosporium secalis) og øjeplet (Cerco-sporella herpotrichoides) samt akssygdomme fremkaldt af arter af Alternaria, Fusarium og Cladosporium. Præparaterne kan også anvendes på ris til bekæmpelse af angreb af Pyricularia 30 oryzae, på asbier til bekæmpelse af pletskurv (Venturis inae-qualis) og meldug (Podosphaera leucotricha), på roser til bekæmpelse af meldug (Sphaerothega pannosa) og stråleplet (Di-plocarpon rosae), på agurker til bekæmpelse af meldug (Erysiphe cichoracearum) eller på tomater til bekæmpelse af visnesyge 35 (Alternaria solani).When applying a composition according to the invention to a cereal crop, control of numerous fungal diseases such as mildew (Erysiphe graminis) on wheat, barley, oats and rye 25 and other foliar diseases such as leaf spot disease (Septoria nodorum), radiation spot (Rhyncosporium secalium) and eye spot (Cerco-sporella herpotrichoides) as well as axillary diseases caused by species of Alternaria, Fusarium and Cladosporium. The preparations can also be applied to rice to combat infestations of Pyricularia 30 oryzae, to ash for the control of stain (Venturis inae-qualis) and mildew (Podosphaera leucotricha), to roses to control mildew (Sphaerothega pannosa) and radicle (Di-plop) rosae), on cucumbers for the control of mildew (Erysiphe cichoracearum) or on tomatoes for the control of withered disease 35 (Alternaria solani).

Den koncentration af de virksomme bestanddele i præparatet, der skal føres til en afgrøde i vækst ligger hensigtsmæssigt inden for området 0,0005 til 10 vægt% af præparatet, 2The concentration of the active ingredients in the composition to be fed to a growing crop is conveniently in the range 0.0005 to 10% by weight of the composition, 2

DK 155272 BDK 155272 B

fortrinsvis 0,001 til 5 vægt%. Den mængde af præparatet der føres til afgrøden fx ved sprøjtning, er fortrinsvis en sådan at mængden af de virksomme materialer tilsammen, der føres til en kornafgrøde, ligger i området 100 til 2000 g/ha, fortrinsvis 5 200 til 1000 g/ha, mens den mængde af de virksomme materialer tilsammen, der føres til en havebrugsafgrøde, ligger i området 5 til 1000 g/ha, fortrinsvis 10 til 500 g/ha.preferably 0.001 to 5% by weight. The amount of the composition fed to the crop, for example by spraying, is preferably such that the amount of the active materials together fed to a grain crop is in the range of 100 to 2000 g / ha, preferably 5 200 to 1000 g / ha, while the amount of the active materials brought together into a horticultural crop is in the range of 5 to 1000 g / ha, preferably 10 to 500 g / ha.

Præparatet ifølge opfindelsen kan anvendes i mange former og det bringes ofte mest hensigtsmæssigt i vandig form 10 umiddelbart før anvendelsen. En fremgangsmåde til fremstilling af et sådant præparat kendes under betegnelsen "tankblanding" , ved hvilken to eller flere fungicide bestanddele i deres kommercielle tilgængelige form blandes sammen af brugeren i en passende mængde vand til direkte påføring.The composition of the invention can be used in many forms and it is often most conveniently put into aqueous form 10 immediately before use. A process for preparing such a preparation is known under the term "tank mix" in which two or more fungicidal components in their commercially available form are mixed together by the user in a suitable amount of water for direct application.

15 Foruden tankblanding umiddelbart før brugen kan præ parater indeholdende prochloraz og carbendazim oparbejdes til et mere koncentreret primært præparat som fortyndes med vand eller et andet fortyndingsmiddel før brugen til tilvejebringelse af præparatet som kan tilføres afgrøden ved sprøjtning.In addition to tank mixing immediately prior to use, preparations containing prochloraz and carbendazim can be worked up into a more concentrated primary preparation diluted with water or other diluent prior to use to provide the composition which can be applied to the crop by spraying.

20 Sådanne præparater kan indeholde et overfladeaktivt middel foruden de virksomme bestanddele, og typiske eksempler på præparatformer er emulgerbare koncentrater, dispergerbare pulvere og pulvere til pudring. I et koncentreret primært præparat kan koncentrationen af de virksomme bestanddel varie-25 re inden for vide rammer og kan fx være fra 5 til 95 vægt% af hele præparatet. Det primære præparat fortyndes til tilvejebringelse af præparater til påføring på en afgrøde i vækst, hvor mængden af virksom bestanddel, der tilføres afgrøden, er som anført ovenfor.Such compositions may contain a surfactant in addition to the active ingredients, and typical examples of compositions are emulsifiable concentrates, dispersible powders and powders. In a concentrated primary composition, the concentration of the active ingredient may vary within wide limits and may be, for example, from 5 to 95% by weight of the entire composition. The primary composition is diluted to provide compositions for application to a growing crop where the amount of active ingredient applied to the crop is as set forth above.

30 Et emulgerbart koncentrat, også kendt under betegnel sen "en blandbar væske" omfatter en opløsning af de virksomme bestanddele i et ikke-vandigt opløsningsmiddel sammen med et eller flere emulgeringsmidler. Der dannes en emulsion når det emulgerbare koncentrat blandes med vand.An emulsifiable concentrate, also known as "a miscible liquid" comprises a solution of the active ingredients in a non-aqueous solvent together with one or more emulsifiers. An emulsion is formed when the emulsifiable concentrate is mixed with water.

35 Et dispergerbart pulver indeholder de virksomme bestand dele i findelt form sammen med et eller flere dispergeringsmid-ler således at der dannes en stabil vandig dispersion af de virksomme bestanddele når pulveret blandes med vand. Der ind 3A dispersible powder contains the active ingredient parts in finely divided form together with one or more dispersing agents so that a stable aqueous dispersion of the active ingredients is formed when the powder is mixed with water. There in 3

går som regel· et findelt inert fast fortyndingsmiddel såsom kaolin eller diatomejord, fx det der sælges under varemærket "CELITE" , i det dispergerbare pulver.As a rule, a finely divided inert solid diluent such as kaolin or diatomaceous earth, such as that sold under the trademark "CELITE", goes into the dispersible powder.

Et pulver til pudring indeholder de virksomme bestand-5 dele intimt blandet med et fast, pulverformigt fortyndingsmiddel som fx kaolin.A powder for powder contains the active ingredients intimately mixed with a solid, powdery diluent such as kaolin.

Præparater der indeholder prochloraz kan mest hensigtsmæssigt fremstilles som emulgerbare koncentrater hvori prochloraz og et eller flere emulgeringsmidler er opløst i 10 et ikke-vandigt opløsningsmiddel. Carbendazim er ikke opløselig i nogen nævneværdig grad i de ikke-vandige opløsningsmidler som normalt anvendes, og det er derfor muligt at inkorporere denne forbindelse som dispersioner i emulgerbare koncentrater af prochloraz. Sådanne præparater er de foretruk-15 ne primærpræparater ifølge opfindelsen, og en foretrukken udførelsesform for præparatet er således ejendommeligt ved at det omfatter en dispersion af carbendazim i en opløsning af prochloraz og et eller flere emulgeringsmidler i et ikke-vandigt opløsningsmiddel. I de foretrukne præparater, beskre-20 vet i foregående afsnit, kan mængden af prochloraz ligge i området 5 til 70 vægt%, fortrinsvis 20 til 60%, og mængden af karbendazim kan være i området 1 til 40%, fortrinsvis 5 til 20%.Compositions containing prochloraz may most conveniently be prepared as emulsifiable concentrates in which prochloraz and one or more emulsifiers are dissolved in a non-aqueous solvent. Carbendazim is not soluble to any appreciable degree in the non-aqueous solvents normally used, and it is therefore possible to incorporate this compound as dispersions in emulsifiable concentrates of prochloraz. Such compositions are the preferred primary compositions of the invention, and thus a preferred embodiment of the composition is characterized in that it comprises a dispersion of carbendazime in a solution of prochloraz and one or more emulsifiers in a non-aqueous solvent. In the preferred compositions described in the preceding paragraph, the amount of prochloraz may be in the range of 5 to 70% by weight, preferably 20 to 60%, and the amount of carbendazime may be in the range of 1 to 40%, preferably 5 to 20%. .

De anvendte emulgeringsmidler kan være hvilke som 25 helst af dem der almindeligt anvendes i teknikken på dette område, og de er fortrinsvis non-ioniske overfladeaktive midler, anioniske overfladeaktive midler, en blanding af non-ioniske og anioniske overfladeaktive midler eller kationiske overfladeaktive midler. Den tilstedeværende mængde emulgator 30 kan være op til 30% af hele præparatets vægt. Eksempler på egnede non-ioniske forbindelser er ætoxylerede alkylfenoler såsom nonylfenolætoxylater; ætoxylerede alifatiske alkoholer; ætoxylerede estere; arylfenoler; ætoxylerede alkylolamider; blokpolymerer/copolymerer af ætylenoxyd og propylenoxyd; og 35 alkylolamider. Eksempler på egnede anioniske forbindelser er sulfonater såsom alkylarylsulfonater eller jordoliesulfonater; sulfater såsom alkoholsulfater eller ætersulfater; fosfates 4The emulsifiers used may be any of those commonly used in the art in this field, and are preferably nonionic surfactants, anionic surfactants, a mixture of nonionic and anionic surfactants or cationic surfactants. The amount of emulsifier 30 present may be up to 30% by weight of the entire composition. Examples of suitable nonionic compounds are ethoxylated alkyl phenols such as nonylphenol ethoxylates; ethoxylated aliphatic alcohols; ethoxylated esters; arylfenoler; ethoxylated alkylolamides; block polymers / copolymers of ethylene oxide and propylene oxide; and 35 alkylolamides. Examples of suitable anionic compounds are sulfonates such as alkylarylsulfonates or petroleum sulfonates; sulphates such as alcohol sulphates or ether sulphates; phosphates 4

tere; eller sulfosuccinater. Egnede overfladeaktive midler med kationiske egenskaber er blandt andet ætoxylerede alifatiske aminer, acetater eller oleater af primære eller sekundære alifatiske aminer og kvaternære ammoniumforbindelser.handle; or sulfosuccinates. Suitable surfactants with cationic properties are, among other things, ethoxylated aliphatic amines, acetates or olates of primary or secondary aliphatic amines and quaternary ammonium compounds.

5 Det anvendte ikke-vandige opløsningsmiddel er fortrins vis et vandublandbart opløsningsmiddel, og eksempler på egnede opløsningsmidler er jordoliebaserede aromatiske eller alifatiske kulbrinter såsom benzen, alkylbenzener som fx toluen eller xylen, tung aromatisk nafta og petroleum; naftalen og 1 0 alkylsubstitueret naftalen; klorerede kulbrinter såsom klorbenzener; klorerede alkylbenzener og klorerede alkaner som fx kloroform, kulstoftetraklorid og 1,1,1-triklorætan; keto-niske opløsningsmidler såsom isofoponcyklohexanon, metyliso-butylketon, diisobutylketon eller N-metylpyrrolidon og estere 15 såsom butylbenzoat, dibutylftalat eller dimetylftalat. Det ikke-vandige opløsningsmiddel kan imidlertid også være blandbart med vand, og eksempler på egnede blandbare opløsningsmidler er propoxyglykolætere, diacetonealkohol, dipropylen-glykol, dimetylformamid og dimetylsulfoxyd. Partikelstørrel-20 sen af 2-benzimidazolkarbamatet er hensigtsmæssigt i området 0,5 til 20 μ og er fortrinsvis en sådan at størrelsen af mere end 90% af partikler ligger i området 1 til 10 μ. Partikelstørrelsen kan nedsættes til det ønskede område ved maling ved fx kuglemølle eller homogenisering.Preferably, the non-aqueous solvent used is a water-immiscible solvent, and examples of suitable solvents are petroleum-based aromatic or aliphatic hydrocarbons such as benzene, alkylbenzenes such as toluene or xylene, heavy aromatic naphtha and petroleum; naphthalene and alkyl-substituted naphthalene; chlorinated hydrocarbons such as chlorobenzene; chlorinated alkyl benzenes and chlorinated alkanes such as chloroform, carbon tetrachloride and 1,1,1-trichloroethane; ketonic solvents such as isofoponecyclohexanone, methyl isobutyl ketone, diisobutyl ketone or N-methylpyrrolidone and esters such as butyl benzoate, dibutyl phthalate or dimethyl phthalate. However, the non-aqueous solvent may also be miscible with water, and examples of suitable miscible solvents are propoxy glycol ethers, diacetone alcohol, dipropylene glycol, dimethylformamide and dimethyl sulfoxide. The particle size of the 2-benzimidazole carbamate is suitably in the range of 0.5 to 20 µ and is preferably such that the size of more than 90% of particles is in the range of 1 to 10 µ. The particle size can be reduced to the desired range by painting by, for example, ball mill or homogenization.

25 De foretrukne præparater kan fremstilles ved opløsning af perchloraz og emulgeringsmidlet i opløsningsmidlet og derefter dispergering af carbendazim i opløsningen. Det er også muligt at blande en opløsning af prochloraz i en del af opløsningsmidlet med en dispersion af carbendazim i den resterende 30 opløsningsmiddelmængde, eller man kan opløse prochloraz i en dispersion af carbendazim i opløsningsmidlet.The preferred compositions can be prepared by dissolving perchloraz and the emulsifier in the solvent and then dispersing carbendazime in the solution. It is also possible to mix a solution of prochloraz in a portion of the solvent with a dispersion of carbendazime in the remaining solvent amount, or prochloraz can be dissolved in a dispersion of carbendazime in the solvent.

De foretrukne præparater ifølge opfindelsen blandes med vand til dannelse af et vandigt præparat som kan tilføres en afgrøde i vækst ved sprøjtning. Opfindelsen omfatter som 35 nævnt også en fremgangsmåde til behandling af svampesygdomme i afgrøder i vækst, hvilken fremgangsmåde består i at man til afgrøden fører et sådant vandigt præparat. De primære præparater sættes hensigtsmæssigt til 10 til 1000 rumfang vand ogThe preferred compositions of the invention are mixed with water to form an aqueous composition which can be applied to a growing crop by spraying. The invention also includes, as mentioned, a method for treating fungal diseases in growing crops, the method of which is supplied to the crop such an aqueous preparation. The primary compositions are suitably added to 10 to 1000 volumes of water and

5 omrøres til tilvejebringelse af det vandige præparat som skal udsprøjtes. Den mængde vandigt præparat som føres til afgrøden er fortrinsvis en sådan at prochloraz tilføres til afgrøden i en mængde på 150 til 1000 g/ha og carbendazim i en mængde på 5 40 til 500 g/ha. Det har vist sig at være særligt fordelag tigt, når den til behandling værende afgrøde er en kornafgrøde som fx hvede eller byg, at tilføre et præparat ifølge opfindelsen på en sådan måde at den mængde prochloraz der tilføres afgrøden er i området 300 til 600 g/ha og den mængde carbendazim 10 der føres til afgrøden er i området 80 til 200 g/ha. Ved tilførsel til en kornafgrøde af de foretrukne præparater ifølge opfindelsen bevirkes der bekæmpelse af mange svampesygdomme som fx græssernes meldug (Erysiphe graminis) på hvede, byg, havre og rug og andre bladsygdomme såsom avnepletsyge 15 (Septoria nodorum), stribepletsyge (Rhyncosporium secalis), øjepletsyge (Cercosporella herpotrichoides) og sygdomme på aksene såsom dem der fremkaldes af arter af Alternaria, Fu-sarium og Cladosporium. Præparaterne kan også føres til ris til bekæmpelse af Pyrocylaria oryzae og til have- og gart-20 neriafgrøder såsom æbler, roser, agurker og tomater.5 is stirred to provide the aqueous composition to be sprayed. Preferably, the amount of aqueous composition fed to the crop is such that prochloraz is applied to the crop in an amount of 150 to 1000 g / ha and carbendazime in an amount of 40 to 500 g / ha. It has been found to be particularly advantageous when the crop to be treated is a cereal crop such as wheat or barley, to supply a composition according to the invention in such a way that the amount of prochloraz supplied to the crop is in the range of 300 to 600 g / m ha and the amount of carbendazim 10 fed to the crop is in the range of 80 to 200 g / ha. When applied to a cereal crop of the preferred compositions of the invention, the control of many fungal diseases such as grass mildew (Erysiphe graminis) on wheat, barley, oats and rye and other foliar diseases such as septal disease 15 (Septoria nodorum), strip spotted disease (Rhyncospora), is caused. eye stains (Cercosporella herpotrichoides) and diseases of the axis such as those caused by species of Alternaria, Fu sarium and Cladosporium. The compositions may also be applied to rice for controlling Pyrocylaria oryzae and to garden and garden 20 crops such as apples, roses, cucumbers and tomatoes.

Fungicidet ifølge opfindelsen skal i det følgende belyses nærmere ved et eksempel som beskriver et præparat ifølge opfindelsen og anvendelse deraf.The fungicide according to the invention will be illustrated in the following by an example which describes a composition according to the invention and its use.

Prochloraz og de overfladeaktive midler opløses i xylen og carbendazim dispergeredes i opløsningen. Det resulterende præparat viste sig at være lagerstabilt og at være let dispergerbart i vand, selv efter lang lagringstid.Prochloraz and the surfactants are dissolved in xylene and carbendazime dispersed in the solution. The resulting preparation was found to be storage stable and to be readily dispersible in water, even after a long storage time.

5 Præparatets fungicide aktivitet undersøgtes ved føl gende forsøg.The fungicidal activity of the preparation was investigated by the following experiments.

Det ovenfor beskrevne præparat dispergeredes i vand til frembringelse af et vandigt præparat indeholdende 10 ppm prochloraz og 2,66 ppm carbendazim. Præparatet sprøjtedes på 10 hvede i vækst af stammen "Maris Ranger", der var på væksttrinnet med ét blad. 24 timer senere podedes plantes med en vandig sporesuspension af den patogene svamp Septoria nodorum. Planter holdtes derefter under fugtige betingelser i 7 dage, og det bladareal der var påvirket af den patogene svamp be-15 dømtes visuelt. Det viste sig at det bladareal der var påvirket var betydelig mindre end der iagttoges ved planter som ikke var blevet behandlet med det vandige præparat, hvilket viste at dette virkede som beskyttelsesmiddel mod angreb af den pågældende patogen. Når andre planter af stammen "Maris 20 Ranger" behandledes med et vandigt præparat indeholdende 10 ppm prochloraz eller et vandigt præparat indeholdende 2,66 ppm carbendazim under de ovenfor beskrevne betingelser, indtrådte der kun forsvindende grad af beskyttelsesvirkning.The above described composition was dispersed in water to give an aqueous composition containing 10 ppm prochloraz and 2.66 ppm carbendazim. The composition was sprayed on 10 wheat in the growth of the "Maris Ranger" strain, which was on the single-leaf growth stage. Twenty-four hours later, seed was seeded with an aqueous spore suspension of the pathogenic fungus Septoria nodorum. Plants were then kept under humid conditions for 7 days and the leaf area affected by the pathogenic fungus was visually assessed. It was found that the leaf area affected was significantly smaller than observed in plants that had not been treated with the aqueous preparation, which showed that it acted as a protective agent against the attack of the pathogen in question. When other plants of the "Maris 20 Ranger" strain were treated with an aqueous preparation containing 10 ppm prochloraz or an aqueous preparation containing 2.66 ppm carbendazim under the conditions described above, only a negligible degree of protective effect occurred.

Talmæssigt udtrykt var resultaterne af det ovenfor 25 beskrevne forsøg som følger:In numerical terms, the results of the experiment described above were as follows:
