Description
Herbizide Mittel auf Basis von N-Phosphonomethyl-glvcinestern
Die Erfindung betrifft neue herbizide Mittel, welche aus reinen - nicht formulierten - N-Phosphonomethyl-glycinestern und in Wasser gelösten oder dis¬ pergierten - vorher formulierten - anderen bekannten, herbizid wirksamen Ver¬ bindungen oder Kombinationen von solchen bekannten, herbizid wirksamen Ver¬ bindungen hergestellt werden.
Es ist bekannt, daß einige N-Phosphonomethyl-glycin-alkylester herbizide Eigen- schaften aufweisen und - im allgemeinen in formulierten Anwendungsformen, d.h mit bestimmten Zuschlagsstoffen kombiniert - zur Abtötung von unerwünschten Pflanzen verwendet werden können (vgl. DE 2152826, DE 2166573, US 3977860). Daß reine - d.h. nicht formulierte Wirkstoffe - in Spritzbrühen zur An¬ wendung kommen, ist jedoch nicht üblich.
Es wurde nun gefunden, daß N-Phosphonomethyl-glycinester der allgemeinen For¬ mel (I),
(HO)2P(O)-CH2-NH-CH2-CO-O-R (I)
in welcher
R für Alkyl steht,
- sowie Säureaddukte von Verbindungen der Formel (I) -
als reine Wirkstoffe, d.h. ohne Verwendung weiterer Hilfsstoffe, zu Spritzbruhen von bekannten Herbiziden gegeben werden können und die so hergestellten An¬ wendungsformen mit sehr gutem Erfolg zur Abtötung unerwünschter Pflanzen ver¬ wendet werden können, wobei synergistische Effekte zu beobachten sind
Gegenstand der Erfindung sind somit herbizide Mittel, gekennzeichnet durch einen wirksamen Gehalt an einer synergistischen Wirkstoffkombination bestehend aus
(a) einem N-Phosphonomethyl-glycinester der obigen Formel (I), in welcher R für Alkyl steht, oder einem Säureaddukt dieser Verbindungen ("Wirkstoff der Gruppe 1 ") und
(b) wenigstens einer Verbindung aus der Gruppe der übrigen bekannten Herbizide ("Wirkstoff der Gruppe 2"),
wobei auf 1 Gewichtsteil Wirkstoff der Gruppe 1 jeweils 0,001 bis 1000 Ge¬ wichtsteile Wirkstoff der Gruppe 2 entfallen.
Es ist als ausgesprochen überraschend anzusehen, daß N-Phosphonomethyl-glycin¬ ester der allgemeinen Formel (I) - sowie Säureaddukte von Verbindungen der Formel (I) - in reiner, nicht formulierter Form zur Anwendung in Spritzbrühen be¬ kannter, formulierter Herbizid-Wirkstoffe eingesetzt werden können und daß diese Spritzbrühen im Vergleich mit entsprechenden Anwendungsformen der einzelnen Wirkstoffe ausgesprochen synergistische Eigenschaften zeigen.
Die Möglichkeit, die N-Phosphonomethyl-glycinester der Formel (I) ohne Ver- wendung von Formulierungshilfsmitteln direkt in Spritzbrühen einzusetzen, stellt eine wesentliche Vereinfachung der Anwendung und somit eine wertvolle Be¬ reicherung des Standes der Technik dar.

(a) einem N-Phosphonomethyl-glycinester der allgemeinen Formel (I),

("Wirkstoffe der Gruppe 2")
wobei auf 1 Gewichtsteil Wirkstoff der Gruppe 1 jeweils 0,05 bis 50 Gewichtsteile Wirkstoff der Gruppe 2 entfallen.
Als ganz besonders bevorzugter Wirkstoff der Gruppe 1 sei N-Phosphonomethyl- glycin-ethylester genannt
Als Säureaddukte sind im Zusammenhang mit der vorliegenden Erfindung all¬ gemein Additionsprodukte aus Verbindungen der Formel (I) und Sauren zu ver-
stehen Geeignete Sauren sind hierbei vorzugsweise starke Protonensauren, wie z B Hydrogenfluoπd, Hydrogenchloπd (Salzsaure), Hydrogenbromid, Hydrogen- lodid, Schwefelsaure, Phosphorsaure, Trifluoressigsaure, Methansulfonsäure, Ethansulfonsaure, Propansulfonsaure, Butansulfonsaure, Tπfluormethansulfonsaure, Benzolsulfonsaure und p-Toluolsulfonsaure
Die erfindungsgemaß zu verwendenden Verbindungen der Formel (I) sind bereits bekannt und/oder können nach an sich bekannten Verfahren hergestellt werden (vgl DE 2152826, DE 2166573, US 3977860)
Man erhalt die N-Phosphonomethyl-glycinester der allgemeinen Formel (I), wenn man N-Phosphonomethyl-glycin der Formel (II)
(HO)2P(O)-CH2-NH-CH2-COOH (II)
mit einem Alkohol der Formel (III)
HO-R (III)
in welcher
R die oben angegebene Bedeutung hat,
in Gegenwart einer Saure, wie z B Hydrogenchloπd (Chlorwasserstoff), bei Tem¬ peraturen zwischen 40°C und 150°C umsetzt und das hierbei gebildete Säure¬ addukt der Verbindung der Formel (I) - gegebenenfalls nach Zwischenisolierung - mit einem Saurebindemittel, wie z B Triethylamin oder Propylenoxid, bei Temperaturen zwischen 0°C und 60°C umsetzt (vgl die Herstellungsbeispiele)
Es wurde nun überraschend gefunden daß die oben definierten Wirkstoffkombina- ttonen aus den N-Phosphonomethyl-glycinestern der Formel (I) und den oben auf¬ geführten Wirkstoffen der Gruppe 2 eine besonders hohe herbizide Wirksamkeit aufweisen Sie können insbesondere mit sehr gutem Erfolg im semi-selektiven und im nicht-selektiven Bereich der Unkrautbekämpfung eingesetzt werden
Uberraschenderweise ist die herbizide Wirksamkeit der erfindungsgemäßen Wirk¬ stoffkombinationen aus den Verbindungen der oben aufgeführten Gruppen 1 und 2 erheblich höher als die Summe der Wirkungen der einzelnen Wirkstoffe
Es liegt somit ein nicht vorhersehbarer synergistischer Effekt vor und nicht nur eine Wirkungserganzung Die neuen Wirkstoffkombinationen und Anwendungsfor¬ men stellen somit eine wertvolle Bereicherung des Standes der Technik dar
Die erfindungsgemäß zu verwendenden herbiziden Mittel können sowohl in kon¬ ventionellen Anbauverfahren (Reihenkulturen mit geeigneter Reihenweite) in Plantagenkulturen (z B Wein, Obst, Zitrus) sowie in Industrie- und Gleisanlagen, auf Wegen und Platzen, aber auch zur Stoppelbehandlung und beim Minimum-
Tillage-Verfahren eingesetzt werden Sie eignen sich weiterhin als Abbrenner (Krautabtotung z.B in Kartoffeln) oder als Defoliantien (z B in Baumwolle) Ferner sind sind sie für den Einsatz auf Bracheflachen geeignet Weitere Einsatz¬ gebiete sind Baumschulen, Forst, Grünland und Zierpflanzenbau
Als Unkräuter, die durch die erfindungsgemaßen Wirkstoffe bzw Wirkstoffkom¬ binationen gut bekämpft werden können, seien beispielsweise genannt
Dikotyle Unkräuter der Gattungen Sinapis, Lepidium, Galium, Stellaria, Matri- caπa, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Soianum, Cirsium, Carduus, Sonchus, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abu- tilon, Emex, Sida, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranun- culus, Taraxum, Mentha
Monokotyle Unkräuter der Gattungen Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorhum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleochaπs,
Scirpus, Papalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus, Apera
Die Verwendung der erfindungsgemaßen Wirkstoffe und Wirkstoffkombinationen ist jedoch keineswegs auf diese Gattungen beschrankt, sondern erstreckt sich in gleicher Weise auch auf andere Pflanzen
Der synergistische Effekt der erfindungsgemäßen Wirkstoffkombinationen ist bei bestimmten Konzentrationsverhältnissen besonders stark ausgeprägt. Jedoch kön¬ nen die Gewichtsverhältnisse der Wirkstoffe in den Wirkstoffkombinationen in relativ großen Bereichen variiert werden. Im allgemeinen entfallen auf 1 Gewichts- teil Wirkstoff der Gruppe 1 0,001 bis 1000 Gewichtsteile, vorzugsweise 0,01 bis
100 Gewichtsteile und besonders bevorzugt 0,05 bis 50 Gewichtsteile Wirkstoff der Gruppe 2.
Die Aufwandmengen der erfindungsgemäßen Wirkstoffkombinationen können in einem gewissen Bereich variiert werden; sie hängen u.a. vom Wetter und von den Bodenfaktoren ab. Im allgemeinen liegen die Aufwandmengen zwischen 0,05 und 5 kg Wirkstoffkombination pro ha, vorzugsweise zwischen 0,06 und 2 kg pro ha, besonders bevorzugt zwischen 0,1 und 1,0 kg pro ha.
Die erfindungsgemäßen Wirkstoffkombinationen können vor und nach dem Auf¬ laufen der Pflanzen appliziert werden, also im Vorauflauf- und Nachauflauf- Ver- fahren. Sie werden jedoch vorzugsweise im Nachauflauf-Verfahren angewandt.
Die gute herbizide Wirkung der neuen Wirkstoffkombinationen geht aus den nach¬ folgenden Beispielen hervor. Während die einzelnen Wirkstoffe in der herbiziden Wirkung Schwächen aufweisen, zeigen die Kombinationen durchweg eine sehr gute Unkrautwirkung, die über eine einfache Wirkungssummierung hinausgeht.
Ein synergistischer Effekt liegt bei Herbiziden immer dann vor, wenn die herbi¬ zide Wirkung der Wirkstofϊkombination größer ist als die der einzelnen applizier¬ ten Wirkstoffe.
Die zu erwartende Wirkung für eine gegebene Kombination zweier Herbizide kann wie folgt berechnet werden (vgl COLBY, S.R.: "Calculating sy- nergistic and antagonistic responses of herbicide combinations",
Weeds 15, Seiten 20 - 22, 1967) Wenn X = % Schädigung durch Herbizid A (Wirkstoff der Gruppe 1) bei p kg/ha Aufwandmenge und Y = % Schädigung durch Herbizid B (Wirkstoff der Gruppe 2) bei q kg/ha Aufwandmenge und E = die erwartete Schädigung der Herbizide A und B bei p und q kg/ha Aufwandmenge,
dann ist E = X + Y - (X * Y/100).
Ist die tatsächliche Schädigung größer als berechnet, so ist die Kombination in ihrer Wirkung überadditiv, das heißt, sie zeigt einen synergistischen Effekt.
Entsprechende biologische Tests zeigten, daß die herbizide Wirkung der erfin- dungsgemäßen Wirkstoffkombinationen bei den Unkräutern größer ist als die be¬ rechnete, das heißt, daß die neuen Wirkstoffkombinationen synergistisch wirken.
Herstellungsbeispiele:
Beispiel 1
(HO)2P(O)-CH2-NH-CH2-CO-O-C2H5
In eine Suspension von 200 g (1,2 Mol) N-Phosphonomethyl-glycin in 3000 ml Ethanol wird Chlorwasserstoff-Gas bis zur Sättigung eingeleitet. Dann wird die
Reaktionsmischung 3 Stunden unter Rückfluß erhitzt und anschließend - nach Ab¬ kühlen auf Raumtemperatur - im Wasserstrahlvakuum eingeengt. Der Rückstand wird in 1500 ml Ethanol gelöst und zu dieser Lösung wird Triethylamin (ca. 140 g) tropfenweise gegeben, bis ein Farbumschlag von rötlich-braun nach hellgelb er- folgt Das hierbei kristallin anfallende Produkt wird durch Absaugen isoliert
Man erhält 201 g (85% der Theorie) N-Phosphonomethyl-glycin-ethylester vom Schmelzpunkt 203°C.
Die "Trocknung" des gemäß Beispiel 1 erhaltenen Produktes - d.h. die Entfernung des Alkohols - kann - gegebenenfalls mit technisch üblichen Zerkleinerungsver- fahren kombiniert - beispielsweise nach folgenden, technisch üblichen Methoden erfolgen'
Wirbelschichttrocknung, Schaufel trocknung oder Umlufttrocknung (jeweils gegebe¬ nenfalls mit technisch üblichen Zerkleinerungsverfahren, wie z.B. Luftstrahlmah¬ lung, Brechern, Walzen, Mahlen kombiniert).
