Den foreliggende opfindelse angår en fremgangsmåde til behandling eller forebyggelse af fungusinfektioner på planter samt et fungicidt præparat til anvendelse ved fremgangsmåden.The present invention relates to a method for treating or preventing fungal infections on plants and to a fungicidal composition for use in the method.
I britisk patentskrift nr. 1.218.623 beskrives blandt andet et an-5 tal pyrimidinmethanoler, som er nyttige til bekæmpelse af fungi, der angriber planter.British Patent Specification No. 1,218,623 discloses, inter alia, a number of pyrimidine methanols which are useful in controlling fungi that attack plants.
Det har nu vist sig, at to af disse pyrimidinmethanoler, nemlig a-(2-chlorphenyl)-a-(4-chlorphenyl)-5-pyrimidinmethanol (kendt under det generiske navn "fenarimol") og a-(2-chlorphenyl)-a-(4-fluorphenyl)-5-10 pyrimidinmethanol (kendt under det generiske navn "nuarimol") er særligt aktive ved bekæmpelse af fungi som er patogene overfor frugter, såsom æbler. Ydermere har det overraskende vist sig, at disse pyrimidinmethanoler, når de anvendes sammen med captan, er særligt aktive overfor organismerne Uromvces phaseoli var. tvpica, Venturia inaeaualis og 15 Puccinia recondita. Præparaterne ifølge opfindelsen udviser en sy-nergistisk virkning ved bekæmpelsen af disse organismer, d.v.s. at den fungicide virkning af kombinationen er større end den additive virkning af komponenterne, beregnet ved anvendelse af den velkendte "Colby-ligning", se Weeds 15, 20-22 (1967). Præparaterne ifølge opfindelsen er 20 også værdifulde ved bekæmpelse af meldug fPodosphaera leucotrichahIt has now been found that two of these pyrimidine methanols, namely α- (2-chlorophenyl) -α- (4-chlorophenyl) -5-pyrimidine methanol (known by the generic name "fenarimol") and α- (2-chlorophenyl) -a- (4-fluorophenyl) -5-10 pyrimidine methanol (known by the generic name "nuarimol") is particularly active in controlling fungi that are pathogenic to fruits such as apples. Furthermore, it has been surprisingly found that when used with captan, these pyrimidine methanols are particularly active against the organisms Uromvce's phaseoli var. tvpica, Venturia inaeaualis and 15 Puccinia recondita. The compositions of the invention exhibit a synergistic effect in controlling these organisms, i.e. that the fungicidal effect of the combination is greater than the additive effect of the components, calculated using the well-known "Colby equation", see Weeds 15, 20-22 (1967). The compositions of the invention are also valuable in controlling mildew fPodosphaera leucotrichah

Captan er et velkendt fungicid, som kan anvendes til behandling af 20 fungusinfektioner på forskellige fødevareafgrøder, inkl. æbler, som det f.eks. fremgår af U.S.A. patentskrifterne nr. 2.553.770, 2.553.771, 2.553.776 og 2.867.562.Captan is a well-known fungicide that can be used to treat 20 fungal infections on various food crops, incl. apples such as appears in U.S.A. U.S. Patent Nos. 2,553,770, 2,553,771, 2,553,776 and 2,867,562.
I en foretrukket udførelsesform anvendes captan i kombination med "nuarimol".In a preferred embodiment, captan is used in combination with "nuarimol".
25 Kombinationen, der anvendes ifølge opfindelsen, tilføres sædvanligvis afgrøden, som skal behandles, på en sådan måde, at fra 1 til 80 g og fortrinsvis 10 til 80 g/hektar af pyrimidinmethanolen og fra 20 til 1200 g/hektar af captan tilføres afgrødearealet. Det er klart, at den nøjagtige mængde af aktive ingredienser, som tilføres, vil variere indenfor 30 vide grænser, idet den afhænger af variable, såsom dyrkningstætheden, arten af afgrøde og virulensen af den potentielle eller eksisterende infektion, som skal behandles.The combination used according to the invention is usually fed to the crop to be treated in such a way that the crop area is supplied from 1 to 80 g and preferably 10 to 80 g / hectare of the pyrimidine methanol and from 20 to 1200 g / hectare. It will be understood that the exact amount of active ingredient supplied will vary within 30 wide limits, depending on variables such as the cultivation density, the nature of the crop and the virulence of the potential or existing infection to be treated.
Fremgangsmåden ifølge opfindelsen er særlig nyttig i forbindelse med behandling af æbletræer til forebyggelse eller reduktion af fore-35 komsten af skurv (Venturia inaeoualis). Ved en sådan behandling ligger den anvendte mængde af pyrimidinmethanol fortrinsvis fra 20 til 80 g/hektar, og mængden af captan fortrinsvis fra 400 til 1200 g/hektar.The method of the invention is particularly useful in treating apple trees for preventing or reducing the occurrence of scab (Venturia inaeoualis). In such treatment, the amount of pyrimidine methanol used is preferably from 20 to 80 g / hectare and the amount of captan is preferably from 400 to 1200 g / hectare.
Pyrimidinmethanolen og captan kan appliceres adskilt eller sammen 3The pyrimidine methanol and captan can be applied separately or together 3

på æbletræerne, og behandlingen vil sædvanligvis blive gentaget med intervaller på 5 til 20 dage, idet behandlingen indledes, når knopperne brister eller senere, og fortsættes indtil høsttidspunktet, og den aktuelle hyppighed og varighed af behandlingen bestemmes af strengheden af 5 den aktuelle eller forventede sygdom. Det kan også være ønskeligt at fortsætte behandlingen af træerne i hvileperioden om vinteren, i særdeleshed når der har forekommet alvorlig infektionstilstand.on the apple trees, and the treatment will usually be repeated at intervals of 5 to 20 days, the treatment being initiated when the buds burst or later, and continued until harvest time, and the actual frequency and duration of treatment is determined by the severity of the current or expected disease. . It may also be desirable to continue treatment of the trees during the winter rest period, especially when severe infection has occurred.
Når pyrimidinmethanolen og captan appliceres sammen på planterne, som kræver behandling, kan denne kombinerede behandling gennemføres ved 10 blanding af de to aktive ingredienser i sprøjtetanken umiddelbart forud for brug. Det foretrækkes imidlertid at formulere de to aktive ingredienser sammen.i de ønskede forhold til et præparat, som så blot fortyndes forud for brug.When the pyrimidine methanol and captan are applied together on the plants requiring treatment, this combined treatment can be accomplished by mixing the two active ingredients in the spray tank immediately prior to use. However, it is preferred to formulate the two active ingredients together in the desired ratios of a preparation which is then simply diluted prior to use.
I begge tilfælde er det fortyndede vandige præparat, som indeholder 15 begge aktive ingredienser, hidtil ukendt og udgør et middel ifølge opfindelsen. Et sådant præparat kan indeholde fra 0,00005 til 0,007 vægtprocent, fortrinsvis 0,0005 til 0,004 vægtprocent, og særligt foretrukket 0,001 til 0,004 vægtprocent pyrimidinmethanol og fra 0,001 til 0,1 vægtprocent, fortrinsvis 0,001 til 0,06 vægtprocent, og særligt 20 foretrukket 0,03 til 0,06 vægtprocent captan, spor af eventuelle overfladeaktive midler, inerte bærere og lignende, som var til stede i de koncentrerede præparater, som anvendtes til fremstilling af det fortyndede præparat og vand op til 100%.In either case, the dilute aqueous composition containing 15 of both active ingredients is novel and constitutes an agent of the invention. Such a composition may contain from 0.00005 to 0.007% by weight, preferably 0.0005 to 0.004% by weight, and particularly preferably 0.001 to 0.004% by weight pyrimidine methanol and from 0.001 to 0.1% by weight, preferably 0.001 to 0.06% by weight, and particularly preferred. 0.03 to 0.06% by weight of captan, traces of any surfactants, inert carriers and the like present in the concentrated preparations used to prepare the diluted preparation and water up to 100%.
Skønt de anti fungale præparater ifølge opfindelsen kan appliceres 25 på planten, som skal behandles, ved hjælp af en hvilken som helst konventionel teknik, såsom ved sprøjtning, pudring, dypning eller skylning, foretrækkes det at behandle planterne ved at sprøjte den ovennævnte vandige dispersion på planterne. Ved denne behandlingsmåde er det sædvanligvis tilstrækkeligt at de inficerede eller udsatte overflader vædes 30 omhyggeligt med den anvendte flydende dispersion.Although the anti-fungal compositions of the invention can be applied to the plant to be treated by any conventional technique, such as by spraying, powdering, dipping or rinsing, it is preferred to treat the plants by spraying the above aqueous dispersion onto plants. In this mode of treatment, it is usually sufficient that the infected or exposed surfaces are thoroughly wetted with the liquid dispersion used.
Som ovenfor anført, kan de fortyndede præparater ifølge opfindelsen fremstilles ved blanding af de aktive ingredienser umiddelbart før brug eller ved fortynding af et forud fremstillet co-præparat af de to aktive ingredienser. I begge tilfælde vil de aktive ingredienser sædvanligvis 35 være i form af koncentratpræparater, som er således sammensat, at de er i stand til omgående dispergering eller fortynding i vand.As stated above, the diluted compositions of the invention can be prepared by mixing the active ingredients immediately before use or by diluting a pre-prepared co-composition of the two active ingredients. In either case, the active ingredients will usually be in the form of concentrate preparations which are so composed as to be capable of immediate dispersion or dilution in water.
I det tilfælde, hvor de aktive ingredienser formuleres separat, kan captankomponenten anvendes i de sædvanlige kommercielt tilgængelige 4In the case where the active ingredients are formulated separately, the captan component can be used in the usual commercially available 4
DK 152661 BDK 152661 B
former, f.eks. i form af et 50% eller 83% befugteligt pulver. På lignende måde kan pyrimidinmethanolkomponenten f.eks. være formuleret som et 4% eller 10% befugteligt pulver eller som et 5% emulgerbart koncentrat. Almindeligvis kan imidlertid alle hensigtsmæssige koncentratpræparater 5 anvendes, og de kan indeholde fra ca. 1 til ca. 90 vægtprocent af de enkelte aktive ingredienser.forms, e.g. in the form of a 50% or 83% wettable powder. Similarly, the pyrimidine methanol component may e.g. be formulated as a 4% or 10% wettable powder or as a 5% emulsifiable concentrate. In general, however, all suitable concentrate compositions 5 may be used and may contain from about 1 to approx. 90% by weight of the individual active ingredients.
I det tilfælde, hvor de aktive ingredienser er formuleret sammen i koncentratpræparater, er sidstnævnte hidtil ukendte, og de udgør midler ifølge opfindelsen. Sådanne koncentrater kan indeholde fra 5 til 90 10 vægtprocent ialt af de aktive ingredienser, idet sidstnævnte fortrinsvis er til stede i et forhold af captan til pyrimidinmethanol fra 2:1 til 25:1 på vægtbasis.In the case where the active ingredients are formulated together in concentrate formulations, the latter are novel and constitute agents of the invention. Such concentrates may contain from 5 to 90% by weight in total of the active ingredients, the latter being preferably present in a ratio of captan to pyrimidine methanol from 2: 1 to 25: 1 by weight.
Koncentratpræparaterne ifølge opfindelsen indeholder sædvanligvis de aktive ingredienser i de ovenfor anførte mængder, en eller flere 15 inerte bærere og eventuelt et eller flere overfladeaktive midler, fortykningsmidler, anti frysningsmidler og konserveringsmidler. Koncentraterne kan være faste stoffer, sædvanligvis kendt som befugtelige pulvere eller vandige suspensioner.The concentrate compositions of the invention usually contain the active ingredients in the amounts listed above, one or more inert carriers, and optionally one or more surfactants, thickeners, anti-freezing agents and preservatives. The concentrates may be solids, usually known as wettable powders or aqueous suspensions.
Befugtelige pulvere omfatter en omhyggelig blanding af de aktive 20 ingredienser, en eller flere inerte bærere og passende overfladeaktive midler. Den inerte bærer kan udvælges blandt attapulgitierarterne, mont-mori11onitierarterne, diatoméjordarterne, kaolinarterne, glimmerarterne, talkumarterne og rensede silicater. Effektive overfladeaktive midler kan findes blandt de sulfonerede ligniner, naphthalensulfonaterne og de kon-25 denserede naphtha!ensulfonater, al kyl succinaterne, al kyl- benzensulfonaterne, al kyl sul faterne, og de non-ioniske overfladeaktive midler, såsom ethylenoxidadditi onsforbindelser af phenol. Eksempler på befugtelige pulverpræparater, som ligger indenfor opfindelsens omfang er 30 vægtprocent (a) Pyrimidinmethanol 1-15Wettable powders comprise a careful blend of the active ingredients, one or more inert carriers, and appropriate surfactants. The inert carrier can be selected from the attapulgitic species, the mont-moronite species, the diatomaceous earths, the kaolin species, the mica species, the talc species and the purified silicates. Effective surfactants can be found among the sulfonated lignins, the naphthalenesulfonates and the condensed naphthalene sulfonates, all the cool succinates, all the chylbenzenesulfonates, all the coolants, and the nonionic surfactants such as ethylene oxide addition compounds of phenol.

Hvedeplanter af varieteten Monon dyrkedes i formstofpotter, idet hver potte indeholdt omkring 50 hvedeplanter. Hver behandlingsopløsning sprøjtedes på planterne i to formstofspotter på det tidspunkt, hvor planterne var syv dage gamle, idet sprøjtningen fortsattes indtil opløs-5 ningen løb af planterne. Efter tørring inokuleredes planterne med sporer af hvederustfungusen, og potterne og planterne anbragtes i et fugtkammer i ca. 40 timer og flyttedes dernæst til væksthuset for fremkaldelse af sygdommen.Wheat plants of the Monon variety were grown in plastic pots, each pot containing about 50 wheat plants. Each treatment solution was sprayed onto the plants in two plastic pots at the time the plants were seven days old, spraying continued until the solution ran off the plants. After drying, the plants were inoculated with spores of the wheat rust fungus and the pots and plants were placed in a moisture chamber for approx. 40 hours and then moved to the greenhouse to develop the disease.
To uger efter at planterne var anbragt i væksthuset undersøgtes de 10 visuelt til bestemmelse af den procentuelle sygdomsforekomst, og dette tal omdannedes til procentuel sygdomsbekæmpelse. Resultaterne fremgår af den efterfølgende tabel I.Two weeks after the plants were placed in the greenhouse, the 10 were visually examined to determine the percentage of disease incidence, and this figure was converted to percentage disease control. The results are shown in the following Table I.

Ved at følge samme procedure som beskrevet under forsøg 1 bestemtes 35 virkningen af kombinationer af nuarimol og captan til bekæmpelse af hvedebi adrust (Puccinia recondita) i væksthuset under anvendelse af nuarimolkoncentrationer på 10, 20 eller 40 ppm i kombination med 100 eller 150 ppm captan. Nuarimol undersøgtes også alene i koncentrationer 8Following the same procedure as described in Experiment 1, the effect of combinations of nuarimol and captan to control wheat bee adrust (Puccinia recondita) in the greenhouse was determined using nuarimol concentrations of 10, 20 or 40 ppm in combination with 100 or 150 ppm captan. Nuarimol was also studied alone at concentrations 8
