Definitions

  • the present invention relates to agrochemically active herbicidal compositions and their use for controlling harmful plants.
  • Cinmethyline (CAS RN 87818-31-3) is a racemic mixture of (+/-)-2-exo-(2-methylbenzyloxy)-l-methyl-4-isopropyl-7-oxabicyclo[2. 2. l]heptane.
  • the ratio of the two enantiomers to one another is approximately the same.
  • the preparation of the enantiomerically enriched compounds is known from EP 0 081 893 A2.
  • Ethofumesate (CAS 26225-79-6) is a chemical compound from the benzofuran group used as a selective systemic herbicide.
  • Herbicidal compositions containing cinmethyline and other herbicides are known from various publications, for example: WO 2017/009054 A1, WO 2017/009056 A1, WO 2017/009060 A1, WO 2017/009061 A1, WO 2017/009089 A1, WO 2017/009090 A1, WO 2017/009092 A1, WO 2017/009095 A1, WO2017009124A1, WO 2017/009134 A1, WO 2017/009137 A1, WO 2017/009138 A1, WO 2017/009139 A1, WO 2017/009140 A1, WO 09142/ WO 09140 A1 A1, WO 2017/009143 A1, WO 20177009144 A1, WO 2017/009145 A1, WO 2017/009146 A1, WO 2017/009147 A1.
  • herbicidal compositions extend the spectrum of weeds to be controlled compared to the respective individual active ingredients, but without opening up further possible uses, such as use in other crops of useful plants or shifting the period of use.
  • These herbicidal compositions known from the prior art also do not solve the problem of the increasing development of resistance in harmful plants to herbicidal active ingredients from the series of HPPD inhibitors, to which cinmethyline also belongs. It is therefore an object of the present invention to provide further herbicidal compositions which make it possible to effectively control unwanted plants in various crops of useful plants in user-friendly time frames.
  • the present invention thus relates to herbicidal compositions containing
  • herbicidal compositions according to the invention can also contain other components, for example other types of crop protection active ingredients and/or additives and/or formulation auxiliaries customary in crop protection, or can be used together with these. Preference is given to herbicidal compositions containing cinmethyline and ethofumesate as the sole agrochemical active ingredients.
  • the herbicidal compositions according to the invention show not only a synergistic effect against unwanted harmful plants, but also other special properties: They can be applied against unwanted harmful plants in crops of useful plants over a wide period of time without the useful plants being significantly damaged.
  • the herbicidal compositions according to the invention can be applied in a manner known to those skilled in the art, for example together (for example as a co-formulation or as a tank mixture) or also in quick succession (splitting), e.g. to the plants, parts of plants, plant seeds or the area where the plants grow. It is possible, for example, to apply the individual active ingredients or the herbicidal compositions in several portions (sequential application), e.g. B. after pre-emergence applications followed by post-emergence applications or after early post-emergence applications followed by mid or late post-emergence applications. Preference is given here to the joint or timely application of components A and B. Application in the pre-emergence to early post-emergence process is also preferred.
  • the application rate of cinmethyline is usually 10 to 1000 g of active substance (ai) per hectare, preferably 200 to 500 g hey/ha.
  • the application rate of ethofumesate (component B) is usually 10 to 500 g of active ingredient per hectare, preferably 100 to 250 g ai/ha.
  • the synergistic effect of the herbicidal compositions according to the invention is particularly pronounced at certain concentration ratios.
  • the weight ratios of components A and B can be varied within relatively wide ranges. In general account for 1 part by weight
  • Active ingredient cinmethyline 0.1 to 10 parts by weight, preferably 0.2 to 2 parts by weight of ethofumesate.
  • herbicidal compositions according to the invention When used, a very broad spectrum of harmful plants is controlled pre- and post-emergence, for example annual and perennial monocotyledonous or dicotyledonous weeds and undesirable crop plants.
  • the herbicidal compositions according to the invention are particularly suitable for use in crops such as cereals, corn, rice, soybeans, oilseed rape, sugar beet, cotton, sugar cane and for use in permanent crops, plantations and on non-crop land. Their use in crops of cereals is preferred.
  • the present invention is therefore also a method for controlling unwanted plants in plant cultures, which is characterized in that components A and B of the herbicidal compositions according to the invention on the plants (e.g. harmful plants such as monocotyledonous or dicotyledonous weeds or unwanted crops), or the area where the plants grow are applied, e.g. together or separately.
  • components A and B of the herbicidal compositions according to the invention on the plants e.g. harmful plants such as monocotyledonous or dicotyledonous weeds or unwanted crops
  • the area where the plants grow are applied, e.g. together or separately.
  • Undesirable plants are understood to mean all plants that grow in places where they are undesired. These can be, for example, harmful plants (e.g. monocotyledonous or dicotyledonous weeds or undesired crop plants).

  • the invention also relates to the use of the herbicidal compositions according to the invention for controlling undesired plant growth, preferably in crops of useful plants.
  • the herbicidal compositions according to the invention can be prepared by known methods, e.g. as mixed formulations of the individual components, optionally with other active ingredients, additives and/or customary formulation auxiliaries, which are then used diluted in the usual manner with water, or as so-called tank mixes by joint dilution of the separately formulated or partially separately formulated individual components are produced with water. It is also possible to apply the separately formulated or partially separately formulated individual components at different times (split application). It is also possible to use the individual components or the herbicidal compositions in several portions (sequential application), e.g. B. after pre-emergence applications followed by post-emergence applications or after early post-emergence applications followed by mid or late post-emergence applications. Preference is given to the joint or timely use of the active ingredients of the respective combination.

Description

Herbizide Zusammensetzungen enthaltend Cinmethylin und Ethofumesat Herbicidal compositions containing cinmethyline and ethofumesate
Beschreibung description
Die vorliegende Erfindung betrifft agrochemisch wirksame herbizide Zusammensetzungen sowie deren Verwendung zur Bekämpfung von Schadpflanzen. The present invention relates to agrochemically active herbicidal compositions and their use for controlling harmful plants.
Cinmethylin (CAS RN 87818-31-3) ist ein racemisches Gemisch von (+/-)-2-exo-(2-Methylbenzyloxy)- l-methyl-4-isopropyl-7-oxabicyclo[2. 2. l]heptan. Cinmethyline (CAS RN 87818-31-3) is a racemic mixture of (+/-)-2-exo-(2-methylbenzyloxy)-l-methyl-4-isopropyl-7-oxabicyclo[2. 2. l]heptane.
Dabei ist das Verhältnis der beiden Enantiomere zueinander in etwa gleich. Die Herstellung der enantiomerenangereicherten Verbindungen ist bekannt aus EP 0 081 893 A2. The ratio of the two enantiomers to one another is approximately the same. The preparation of the enantiomerically enriched compounds is known from EP 0 081 893 A2.
Ethofumesat (CAS 26225-79-6) ist eine chemische Verbindung aus der Gruppe der Benzofürane, die als selektives systemisches Herbizid verwendet wird. Ethofumesate (CAS 26225-79-6) is a chemical compound from the benzofuran group used as a selective systemic herbicide.
Aus verschiedenen Schriften sind herbizide Zusammensetzungen enthaltend Cinmethylin und weitere Herbizide bekannt, so z.B.: WO 2017/009054 Al, WO 2017/009056 Al, WO 2017/009060 Al, WO 2017/009061 Al, WO 2017/009089 Al, WO 2017/009090 Al, WO 2017/009092 Al, WO 2017/009095 Al , WO2017009124A1, WO 2017/009134 Al, WO 2017/009137 Al, WO 2017/009138 Al, WO 2017/009139 Al, WO 2017/009140 Al, WO 2017/009142 Al, WO 2017/009143 Al, WO 20177009144 Al, WO 2017/009145 Al, WO 2017/009146 Al, WO 2017/009147 Al. Diese herbizide Zusammensetzungen erweitern das zu bekämpfende Unkrautspektrum gegenüber den jeweiligen einzelnen Wirkstoffen ohne jedoch weitere Anwendungsmöglichkeiten, wie Einsatz in anderen Kulturen von Nutzpflanzen oder Verschiebung des Anwendungszeitraums zu erschliessen. Auch lösen diese aus dem Stand der Technik bekannten herbiziden Zusammensetzungen nicht das Problem der zunehmenden Resistenzbildung von Schadpflanzen gegenüber herbiziden Wirkstoffen aus der Reihe der HPPD- Inhibitoren, zu denen auch Cinmethylin gehört. Aufgabe der vorliegenden Erfindung ist es daher, weitere herbizide Zusammensetzungen bereitzustellen, die eine gute Bekämpfung unerwünschter Pflanzen in verschiedenen Kulturen von Nutzpflanzen in anwenderfreundlichen Zeitfenstem ermöglichen. Herbicidal compositions containing cinmethyline and other herbicides are known from various publications, for example: WO 2017/009054 A1, WO 2017/009056 A1, WO 2017/009060 A1, WO 2017/009061 A1, WO 2017/009089 A1, WO 2017/009090 A1, WO 2017/009092 A1, WO 2017/009095 A1, WO2017009124A1, WO 2017/009134 A1, WO 2017/009137 A1, WO 2017/009138 A1, WO 2017/009139 A1, WO 2017/009140 A1, WO 09142/ WO 09140 A1 A1, WO 2017/009143 A1, WO 20177009144 A1, WO 2017/009145 A1, WO 2017/009146 A1, WO 2017/009147 A1. These herbicidal compositions extend the spectrum of weeds to be controlled compared to the respective individual active ingredients, but without opening up further possible uses, such as use in other crops of useful plants or shifting the period of use. These herbicidal compositions known from the prior art also do not solve the problem of the increasing development of resistance in harmful plants to herbicidal active ingredients from the series of HPPD inhibitors, to which cinmethyline also belongs. It is therefore an object of the present invention to provide further herbicidal compositions which make it possible to effectively control unwanted plants in various crops of useful plants in user-friendly time frames.
Diese Aufgabe wurde durch die Bereitstellung von herbiziden Zusammensetzungen enthaltend Cinmethylin und Ethofumesat gelöst. This problem was solved by providing herbicidal compositions containing cinmethyline and ethofumesate.
Gegenstand der vorliegenden Erfindung sind somit herbizide Zusammensetzungen, enthaltend The present invention thus relates to herbicidal compositions containing
(A) Cinmethylin (Komponente A), und (A) cinmethyline (Component A), and
(B) Ethofumesat (Komponente B). (B) Ethofumesate (Component B).
Bevorzugt sind herbizide Zusammensetzungen, enthaltend als einzige herbizde Wirkstoffe Preference is given to herbicidal compositions containing the only herbicidal active ingredients
(A) Cinmethylin, und (A) cinmethyline, and
(B) Ethofumesat. (B) ethofumesate.
Die erfindungsgemäßen herbiziden Zusammensetzungen können zusätzlich weitere Komponenten, beispielsweise Pflanzenschutzmittelwirkstoffe anderer Art und/oder im Pflanzenschutz übliche Zusatzstoffe und/oder Formulierungshilfsmittel, enthalten oder zusammen mit diesen eingesetzt werden. Bevorzugt sind herbizide Zusammensetzungen, enthaltend Cinmethylin und Ethofumesat als einzige agrochemische Wirkstoffe. The herbicidal compositions according to the invention can also contain other components, for example other types of crop protection active ingredients and/or additives and/or formulation auxiliaries customary in crop protection, or can be used together with these. Preference is given to herbicidal compositions containing cinmethyline and ethofumesate as the sole agrochemical active ingredients.
Die erfmdungsgemäßen herbiziden Zusammensetzungen zeigen überraschender-weise nicht nur einen synergistischen Effekt gegen unerwünschte Schadpflanzen, sondern darüberhinaus weitere besondere Eigenschaften: So sind sie in einem weiten Zeitfenster in Kulturen von Nutzpflanzen gegen unerwünschte Schadpflanzen applizierbar, ohne dass die Nutzpflanzen nennenswert geschädigt werden. Surprisingly, the herbicidal compositions according to the invention show not only a synergistic effect against unwanted harmful plants, but also other special properties: They can be applied against unwanted harmful plants in crops of useful plants over a wide period of time without the useful plants being significantly damaged.
Die erfmdungsgemäßen herbiziden Zusammensetzungen können auf dem Fachmann bekannte Weise angewendet werden, beispielsweise gemeinsam (beispielsweise als Co-Formulierung oder als Tank- Mischung) oder auch zeitlich kurz hintereinander versetzt (Splitting), z.B. auf die Pflanzen, Pflanzenteile, Pflanzensamen oder die Fläche, auf der die Pflanzen wachsen. Möglich ist z.B. die Anwendung der Einzelwirkstoffe oder der herbiziden Zusammensetzungen in mehreren Portionen (Sequenzanwendung), z. B. nach Anwendungen im Vorauflauf, gefolgt von Nachauflauf- Applikationen oder nach frühen Nachauflaufanwendungen, gefolgt von Applikationen im mittleren oder späten Nachauflauf. Bevorzugt ist dabei die gemeinsame oder die zeitnahe Anwendung der Komponentem A und B. Ebenso bevorzugt ist die Anwendung im Vorauflauf- bis zum frühen NachauflaufVerfahren. The herbicidal compositions according to the invention can be applied in a manner known to those skilled in the art, for example together (for example as a co-formulation or as a tank mixture) or also in quick succession (splitting), e.g. to the plants, parts of plants, plant seeds or the area where the plants grow. It is possible, for example, to apply the individual active ingredients or the herbicidal compositions in several portions (sequential application), e.g. B. after pre-emergence applications followed by post-emergence applications or after early post-emergence applications followed by mid or late post-emergence applications. Preference is given here to the joint or timely application of components A and B. Application in the pre-emergence to early post-emergence process is also preferred.
In den erfindungsgemäßen herbiziden Zusammensetzungen beträgt die Aufwandmenge von Cinmethylin (Komponente A) üblicherweise 10 bis 1000 g Aktivsusbstanz (a. i.) pro Hektar, bevorzugt 200 bis 500 g a. i./ha. Die Aufwandmenge von Ethofumesat (Komponente B) beträgt üblicherweise 10 bis 500 g Aktivsubstanz pro Hektar, bevorzugt 100 bis 250 g a. i./ha. In the herbicidal compositions according to the invention, the application rate of cinmethyline (component A) is usually 10 to 1000 g of active substance (ai) per hectare, preferably 200 to 500 g hey/ha. The application rate of ethofumesate (component B) is usually 10 to 500 g of active ingredient per hectare, preferably 100 to 250 g ai/ha.
Der synergistische Effekt der erfmdungsgemäßen herbiziden Zusammensetzungen ist bei bestimmten Konzentrationsverhältnissen besonders stark ausgeprägt. Jedoch können die Gewichtsverhältnisse der Komponenten A und B in relativ großen Bereichen variiert werden. Im allgemeinen entfallen auf 1 Gewichtsteil The synergistic effect of the herbicidal compositions according to the invention is particularly pronounced at certain concentration ratios. However, the weight ratios of components A and B can be varied within relatively wide ranges. In general account for 1 part by weight
Wirkstoff Cinmethylin 0,1 bis 10 Gewichtsteile, vorzugsweise 0,2 bis 2 Gewichtsteile Ethofumesat. Active ingredient cinmethyline 0.1 to 10 parts by weight, preferably 0.2 to 2 parts by weight of ethofumesate.
Bei Anwendung der erfmdungsgemäßen herbiziden Zusammensetzungen wird im Vor- und NachauflaufVerfahren ein sehr breites Spektrum an Schadpflanzen bekämpft, z.B. annuellen und perennierenden mono- oder dikotylen Unkräutern sowie an unerwünschten Kulturpflanzen. Die erfmdungsgemäßen herbiziden Zusammensetzungen eignen sich besonders zum Einsatz in Kulturen wie Getreide, Mais, Reis, Soja, Raps, Zuckerrüben, Baumwolle, Zuckerrohr sowie für den Einsatz in Dauerkulturen, Plantagen und auf Nichtkulturland. Bevorzugt ist ihre Anwendung in Kulturen von Getreide. When the herbicidal compositions according to the invention are used, a very broad spectrum of harmful plants is controlled pre- and post-emergence, for example annual and perennial monocotyledonous or dicotyledonous weeds and undesirable crop plants. The herbicidal compositions according to the invention are particularly suitable for use in crops such as cereals, corn, rice, soybeans, oilseed rape, sugar beet, cotton, sugar cane and for use in permanent crops, plantations and on non-crop land. Their use in crops of cereals is preferred.
Gegenstand der vorliegenden Erfindung ist somit weiterhin ein Verfahren zur Bekämpfung von unerwünschten Pflanzen in Pflanzenkulturen, das dadurch gekennzeichnet ist, dass die Komponenten A und B der erfmdungsgemäßen herbiziden Zusammensetzungen auf die Pflanzen (z.B. Schadpflanzen wie mono- oder dikotyle Unkräuter oder unerwünschte Kulturpflanzen), oder die Fläche, auf der die Pflanzen wachsen ausgebracht werden, z.B. gemeinsam oder getrennt. The present invention is therefore also a method for controlling unwanted plants in plant cultures, which is characterized in that components A and B of the herbicidal compositions according to the invention on the plants (e.g. harmful plants such as monocotyledonous or dicotyledonous weeds or unwanted crops), or the area where the plants grow are applied, e.g. together or separately.
Unter unerwünschten Pflanzen sind alle Pflanzen zu verstehen, die an Orten wachsen, wo sie unerwünscht sind. Dies können z.B. Schadpflanzen (z.B. mono- oder dikotyle Unkräuter oder unerwünschte Kulturpflanzen) sein. Undesirable plants are understood to mean all plants that grow in places where they are undesired. These can be, for example, harmful plants (e.g. monocotyledonous or dicotyledonous weeds or undesired crop plants).
Monokotyle Unkräuter entstammen z.B. den Gattungen Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus, Apera.

The invention also relates to the use of the herbicidal compositions according to the invention for controlling undesired plant growth, preferably in crops of useful plants.
Die erfmdungsgemäßen herbiziden Zusammensetzungen können nach bekannten Verfahren z.B. als Mischformulierungen der Einzelkomponenten, gegebenenfalls mit weiteren Wirkstoffen, Zusatzstoffen und/oder üblichen Formulierungshilfsmitteln hergestellt werden, die dann in üblicher Weise mit Wasser verdünnt zur Anwendung gebracht werden, oder als sogenannte Tankmischungen durch gemeinsame Verdünnung der getrennt formulierten oder partiell getrennt formulierten Einzelkomponenten mit Wasser hergestellt werden. Ebenfalls möglich ist die zeitlich versetzte Anwendung (Splitapplikation) der getrennt formulierten oder partiell getrennt formulierten Einzelkomponenten. Möglich ist auch die Anwendung der Einzelkomponenten oder der herbiziden Zusammensetzungen in mehreren Portionen (Sequenzanwendung), z. B. nach Anwendungen im Vorauflauf, gefolgt von Nachauflauf-Applikationen oder nach frühen Nachauflaufanwendungen, gefolgt von Applikationen im mittleren oder späten Nachauflauf. Bevorzugt ist dabei die gemeinsame oder die zeitnahe Anwendung der Wirkstoffe der jeweiligen Kombination. The herbicidal compositions according to the invention can be prepared by known methods, e.g. as mixed formulations of the individual components, optionally with other active ingredients, additives and/or customary formulation auxiliaries, which are then used diluted in the usual manner with water, or as so-called tank mixes by joint dilution of the separately formulated or partially separately formulated individual components are produced with water. It is also possible to apply the separately formulated or partially separately formulated individual components at different times (split application). It is also possible to use the individual components or the herbicidal compositions in several portions (sequential application), e.g. B. after pre-emergence applications followed by post-emergence applications or after early post-emergence applications followed by mid or late post-emergence applications. Preference is given to the joint or timely use of the active ingredients of the respective combination.

AS/ha: AS/ha:
Soweit in dieser Beschreibung die Abkürzung "AS/ha" verwendet wird, bedeutet dies "Aktivsubstanz pro Hektar“, bezogen auf 100%igen Wirkstoff. Alle Prozentangaben in der Beschreibung sind Gewichtsprozente (Abkürzung: "Gew.-%") und beziehen sich, wenn nicht anders definiert, auf das relative Gewicht der jeweiligen Komponente bezogen auf das Gesamtgewicht der herbiziden Mischung/Zusammensetzung (z.B. als Formulierung). If the abbreviation "AS/ha" is used in this description, this means "active substance per hectare", based on 100% active substance. All percentages in the description are percentages by weight (abbreviation: "% by weight") and relate unless otherwise defined, on the relative weight of each component based on the total weight of the herbicidal mixture/composition (e.g. as a formulation).
Die erfmdungsgemäßen herbiziden Zusammensetzungen können auch zur Bekämpfung von Schadpflanzen in Kulturen von bekannten oder noch zu entwickelnden gentechnisch veränderten Pflanzen eingesetzt werden. The herbicidal compositions according to the invention can also be used for controlling harmful plants in crops of genetically modified plants which are known or are yet to be developed.
Die transgenen Pflanzen zeichnen sich in der Regel durch besondere vorteilhafte Eigenschaften aus, beispielsweise durch Resistenzen gegenüber bestimmten Pestiziden, vor allem bestimmten Herbiziden, Resistenzen gegenüber Pflanzenkrankheiten oder Erregern von Pflanzenkrankheiten wie bestimmten Insekten oder Mikroorganismen wie Pilzen, Bakterien oder Viren. Andere besondere Eigenschaften betreffen z. B. das Emtegut hinsichtlich Menge, Qualität, Lagerfähigkeit, Zusammensetzung und spezieller Inhaltsstoffe. So sind transgene Pflanzen mit erhöhtem Stärkegehalt oder veränderter Qualität der Stärke oder solche mit anderer Fettsäurezusammensetzung des Emteguts bekannt. Weitere besondere Eigenschaften können in einer Toleranz oder Resistenz gegen abiotische Stressoren z. B. Hitze, Kälte, Trockenheit, Salz und ultraviolette Strahlung liegen. The transgenic plants are generally distinguished by particularly advantageous properties, for example resistance to certain pesticides, especially certain herbicides, resistance to plant diseases or pathogens of plant diseases such as certain insects or microorganisms such as fungi, bacteria or viruses. Other special properties concern e.g. B. the crop in terms of quantity, quality, shelf life, composition and special ingredients. Thus, transgenic plants with an increased starch content or altered starch quality or those with a different fatty acid composition in the crop are known. Other special properties can be found in tolerance or resistance to abiotic stressors, e.g. B. heat, cold, drought, salt and ultraviolet radiation.
Herkömmliche Wege zur Herstellung neuer Pflanzen, die im Vergleich zu bisher vorkommenden Pflanzen modifizierte Eigenschaften aufweisen, bestehen beispielsweise in klassischen Züchtungsverfahren und der Erzeugung von Mutanten. Alternativ können neue Pflanzen mit veränderten Eigenschaften mit Hilfe gentechnischer Verfahren erzeugt werden (siehe z. B. EP-A-0221044, EP-A-0131624). Beschrieben wurden beispielsweise in mehreren Fällen gentechnische Veränderungen von Kulturpflanzen zwecks Modifikation der in den Pflanzen synthetisierten Stärke (z. B. WO 92/11376, WO 92/14827, WO 91/19806), transgene Kulturpflanzen, welche gegen bestimmte Herbizide vom Typ Glufosinate (vgl. z. B. EP-A-0242236, EP-A-242246) oder Glyphosate (WO 92/00377) oder der Sulfonylharnstoffe (EP-A-0257993, US-A-5013659) resistent sind, transgene Kulturpflanzen, beispielsweise Baumwolle, mit der Fähigkeit Bacillus thuringiensis- Toxine (Bt-Toxine) zu produzieren, welche die Conventional ways of producing new plants that have modified properties compared to previously existing plants include, for example, classical breeding methods and the generation of mutants. Alternatively, new plants with altered properties can be created using genetic engineering methods (see e.g. EP-A-0221044, EP-A-0131624). described For example, in several cases genetic engineering modifications of crop plants for the purpose of modifying the starch synthesized in the plants (e.g. WO 92/11376, WO 92/14827, WO 91/19806), transgenic crop plants which are active against certain herbicides of the glufosinate type (cf e.g. EP-A-0242236, EP-A-242246) or glyphosate (WO 92/00377) or sulfonylureas (EP-A-0257993, US-A-5013659), transgenic crop plants, for example cotton, with the ability to produce Bacillus thuringiensis toxins (Bt toxins), which

Zahlreiche molekularbiologische Techniken, mit denen neue transgene Pflanzen mit veränderten Eigenschaften hergestellt werden können, sind im Prinzip bekannt; siehe z. B. I. Potrykus und G. Spangenberg (eds.) Gene Transfer to Plants, Springer Lab Manual (1995), Springer Verlag Berlin, Heidelberg oder Christou, "Trends in Plant Science" 1 (1996) 423-431). Numerous molecular biological techniques with which new transgenic plants with modified properties can be produced are known in principle; see e.g. B. I. Potrykus and G. Spangenberg (eds.) Gene Transfer to Plants, Springer Lab Manual (1995), Springer Verlag Berlin, Heidelberg or Christou, "Trends in Plant Science" 1 (1996) 423-431).
Für derartige gentechnische Manipulationen können Nucleinsäuremoleküle in Plasmide eingebracht werden, die eine Mutagenese oder eine Sequenzveränderung durch Rekombination von DNA-Sequenzen erlauben. Mit Hilfe von Standardverfahren können z. B. Basenaustausche vorgenommen, Teilsequenzen entfernt oder natürliche oder synthetische Sequenzen hinzugefügt werden. Für die Verbindung der DNA- Fragmente untereinander können an die Fragmente Adaptoren oder Linker angesetzt werden, siehe z. B. Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2. Aufl. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY; oder Winnacker "Gene und Klone", VCH Weinheim 2. Auflage 1996 For such genetic engineering manipulations, nucleic acid molecules can be introduced into plasmids, which allow mutagenesis or sequence modification by recombination of DNA sequences. Using standard procedures, e.g. B. base exchanges are made, partial sequences are removed or natural or synthetic sequences are added. To connect the DNA fragments to one another, adapters or linkers can be attached to the fragments, see e.g. B. Sambrook et al., 1989, Molecular Cloning, A Laboratory Manual, 2nd ed. Cold Spring Harbor Laboratory Press, Cold Spring Harbor, NY; or Winnacker "Genes and Clones", VCH Weinheim 2nd edition 1996
Die Herstellung von Pflanzenzellen mit einer verringerten Aktivität eines Genprodukts kann beispielsweise erzielt werden durch die Expression mindestens einer entsprechenden antisense-RNA, einer sense-RNA zur Erzielung eines Cosuppressionseffektes oder die Expression mindestens eines entsprechend konstruierten Ribozyms, das spezifisch Transkripte des obengenannten Genprodukts spaltet. Hierzu können zum einen DNA-Moleküle verwendet werden, die die gesamte codierende Sequenz eines Genprodukts einschließlich eventuell vorhandener flankierender Sequenzen umfassen, als auch DNA- Moleküle, die nur Teile der codierenden Sequenz umfassen, wobei diese Teile lang genug sein müssen, um in den Zellen einen antisense-Effekt zu bewirken. Möglich ist auch die Verwendung von DNA- Sequenzen, die einen hohen Grad an Homologie zu den codiereden Sequenzen eines Genprodukts aufweisen, aber nicht vollkommen identisch sind. The production of plant cells with a reduced activity of a gene product can be achieved, for example, by expressing at least one corresponding antisense RNA, a sense RNA to achieve a cosuppression effect or the expression of at least one correspondingly constructed ribozyme that specifically cleaves transcripts of the above gene product. For this purpose, on the one hand, DNA molecules can be used which include the entire coding sequence of a gene product, including any flanking sequences present, as well as DNA molecules which only include parts of the coding sequence, these parts having to be long enough to enter the cells produce an antisense effect. It is also possible to use DNA sequences which have a high degree of homology to the coding sequences of a gene product but are not completely identical.
Bei der Expression von Nucleinsäuremolekülen in Pflanzen kann das synthetisierte Protein in jedem beliebigen Kompartiment der pflanzlichen Zelle lokalisiert sein. Um aber die Lokalisation in einem bestimmten Kompartiment zu erreichen, kann z. B. die codierende Region mit DNA-Sequenzen verknüpft werden, die die Lokalisierung in einem bestimmten Kompartiment gewährleisten. Derartige Sequenzen sind dem Fachmann bekannt (siehe beispielsweise Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al., Proc. Natl. Acad. Sei. USA 85 (1988), 846-850; Sonnewald et al., Plant J. 1 (1991), 95-106). Die Expression der Nukleinsäuremoleküle kann auch in den Organellen der Pflanzenzellen stattfinden. When nucleic acid molecules are expressed in plants, the synthesized protein can be located in any compartment of the plant cell. However, in order to achieve localization in a specific compartment, e.g. B. the coding region can be linked to DNA sequences that ensure localization in a specific compartment. Such sequences are known to those skilled in the art (see, for example, Braun et al., EMBO J. 11 (1992), 3219-3227; Wolter et al., Proc. Natl. Acad. Sci. USA 85 (1988), 846-850; Sonnewald et al. (1991) Plant J. 1:95-106). The expression of the nucleic acid molecules can also take place in the organelles of the plant cells.
Die transgenen Pflanzenzellen können nach bekannten Techniken zu ganzen Pflanzen regeneriert werden. Bei den transgenen Pflanzen kann es sich prinzipiell um Pflanzen jeder beliebigen Pflanzenspezies handeln, d.h., sowohl monokotyle als auch dikotyle Pflanzen. The transgenic plant cells can be regenerated into whole plants using known techniques. In principle, the transgenic plants can be plants of any desired plant species, i.e. both monocotyledonous and dicotyledonous plants.
So sind transgene Pflanzen erhältlich, die veränderte Eigenschaften durch Überexpression, Suppression oder Inhibierung homologer (= natürlicher) Gene oder Gensequenzen oder Expression heterologer (= fremder) Gene oder Gensequenzen aufweisen. It is thus possible to obtain transgenic plants which have modified properties as a result of overexpression, suppression or inhibition of homologous (=natural) genes or gene sequences or expression of heterologous (=foreign) genes or gene sequences.
Vorzugsweise können die erfindungsgemäßen Zusammensetzungen in transgenen Kulturen eingesetzt werden, welche gegen Wuchsstoffe, wie z. B. Dicamba oder gegen Herbizide, die essentielle Pflanzenenzyme, z. B. Acetolactatsynthasen (ALS), EPSP Synthasen, Glutaminsynthasen (GS) oder Hydroxyphenylpyruvat Dioxygenasen (HPPD) hemmen, respektive gegen Herbizide aus der Gruppe der Sulfonylharnstoffe, der Glyphosate, Glufosinate oder Benzoylisoxazole und analogen Wirkstoffe, resistent sind. Preferably, the compositions of the invention can be used in transgenic crops which against growth substances such. B. dicamba or against herbicides that destroy essential plant enzymes, e.g. B. acetolactate synthases (ALS), EPSP synthases, glutamine synthases (GS) or hydroxyphenylpyruvate dioxygenases (HPPD), respectively, are resistant to herbicides from the group of sulfonylureas, glyphosate, glufosinate or benzoylisoxazoles and analogous active ingredients.
Bei der Anwendung der erfindungsgemäßen Zusammensetzungen in transgenen Kulturen treten neben den in anderen Kulturen zu beobachtenden Wirkungen gegenüber Schadpflanzen oftmals Wirkungen auf, die für die Applikation in der jeweiligen transgenen Kultur spezifisch sind, beispielsweise ein verändertes oder speziell erweitertes Unkrautspektrum, das bekämpft werden kann, veränderte Aufwandmengen, die für die Applikation eingesetzt werden können, vorzugsweise gute Kombinierbarkeit mit den Herbiziden, gegenüber denen die transgene Kultur resistent ist, sowie Beeinflussung von Wuchs und Ertrag der transgenen Kulturpflanzen. Gegenstand der Erfindung ist deshalb auch die Verwendung der erfindungsgemäßen Zusammensetzungen zur Bekämpfung von Schadpflanzen in transgenen Kulturpflanzen. When the compositions according to the invention are used in transgenic cultures, in addition to the effects observed in other cultures against harmful plants, there are often effects that are specific to the application in the respective transgenic culture, for example a modified or specially expanded spectrum of weeds that can be controlled Application rates that can be used for the application, preferably good combinability with the herbicides to which the transgenic crop is resistant, and influencing the growth and yield of the transgenic crop plants. The invention therefore also relates to the use of the compositions according to the invention for combating harmful plants in transgenic crop plants.
Bevorzugt ist die Anwendung der erfindungsgemäßen Zusammensetzungen in wirtschaftlich bedeutenden transgenen Kulturen von Nutz- und Zierpflanzen, z. B. von Getreide (z.B. Weizen, Gerste, Roggen, Hafer), Hirse, Reis, Maniok und Mais oder auch Kulturen von Zuckerrübe, Baumwolle, Soja, Raps, Kartoffel, Tomate, Erbse und anderen Gemüsekulturen, insbesonder in Mais, Baumwolle und Soja. Preference is given to using the compositions according to the invention in economically important transgenic crops of useful and ornamental plants, e.g. B. from cereals (e.g. wheat, barley, rye, oats), millet, rice, cassava and corn or crops of sugar beet, cotton, soybeans, rapeseed, potatoes, tomatoes, peas and other vegetable crops, especially in corn, cotton and soybeans .
Gegenstand der Erfindung ist deshalb auch die Verwendung der erfmdungsgemäßen Zusammensetzungen zur Bekämpfung von Schadpflanzen in transgenen Kulturpflanzen oder Kulturpflanzen, die Toleranz durch Selektionszüchtung aufweisen. The subject matter of the invention is therefore also the use of the compositions according to the invention for combating harmful plants in transgenic crop plants or crop plants which exhibit tolerance as a result of selective breeding.

Die Samen der oben genannten Biotypen wurden in 8 cm Töpfe (LSI; pH 7,4; % C org 2,2) gesät. Die Temperatur wurde bei ca. 23°/15°C Tag/Nacht gehalten. Nach der Anwendung der Herbizide (300 1 Wasser/ha) wurden die Töpfe nach Bedarf von unten bewässert. Es wurden zwei Versuche durchgeführt. In einem Vorauflauf- Versuch wurden die Herbizide direkt nach der Aussaat im Wachstumsstadium BBCH 00 ausgebracht. In einem Nachauflauf-Versuch wurden die Herbizide im Wachstumsstadium BBCH 11-12 ausgebracht. The seeds of the above biotypes were sown in 8 cm pots (LSI; pH 7.4; % C org 2.2). Temperature was maintained at approximately 23°/15°C day/night. After application of the herbicides (300 l water/ha), the pots were sub-irrigated as needed. Two experiments were carried out. In a pre-emergence trial, the herbicides were applied directly after sowing at the BBCH 00 growth stage. In a post-emergence experiment, the herbicides were applied at the BBCH 11-12 growth stage.
Der Herbizidwirkstoff Cinmethylin wurde als handelsübliches emulgierbares Konzentrat (EC) LUMIMAX verwendet. Ethofümesat wurde als handelsübliches Suspensionskonzentrat (SC) Nortron verwendet. Den Spritzflüssigkeiten wurde ein methyliertes Samenöl (Mero) in einer Menge von 1 1/ha zugesetzt, um ein gutes Rückhalteverhalten zu gewährleisten. The herbicide active ingredient cinmethylin was used as a commercially available emulsifiable concentrate (EC) LUMIMAX. Ethofumesate was used as a commercial suspension concentrate (SC) Nortron. A methylated seed oil (Mero) was added to the spray liquids in an amount of 1 1/ha in order to ensure good retention behavior.
Bewertung valuation
Der prozentuale Anteil der Unkrautbekämpfung (2 Wiederholungen) wurde 27 Tage nach der Herbizidanwendung (DAA) auf einer Skala von 0-100 bewertet. Eine Bewertung von 0 bedeutet keine Kontrolle und 100 bedeutet vollständige Kontrolle. Berechnung des Synergismus nach Colbv Percent weed control (2 replicates) was rated 27 days after herbicide application (DAA) on a 0-100 scale. A rating of 0 means no control and 100 means complete control. Calculation of the synergism according to Colbv
Nach Colby sind synergistische Effekte von Herbizidwirkstoffen angezeigt, wenn die gemessene Wirksamkeit höher ist als die erwartete, die nach seiner Formel für 2-fach-Mischungen berechnet wird EC = A + B - (AxB)/100 According to Colby, synergistic effects of herbicide active ingredients are indicated when the measured effectiveness is higher than that expected, calculated according to his formula for 2-fold mixtures EC = A + B - (AxB)/100
