Description
Mittel zur Beeinflussung des Pflanzenwachstums, insbesondere zur Bekämpfung von Unkraut Es hat sich überraschenderweise gezeigt, dass Triazine der Formel
EMI0001.0004
worin X und Y Sauerstoff oder Schwefel, n 0 oder 1, R, R1 und R2 Wasserstoff oder Kohlenwasserstoff reste bedeuten, bereits in sehr niedriger Konzentra tion auf Pflanzen wachstumshemmend und abtötend wirken.
Verbindungen der oben definierten Formel sind zum Beispiel durch Umsetzung von Cyanurchlorid mit geeigneten Alkoholen oder Mercaptanen und Aminen, gegebenenfalls gefolgt von reduktiver Ent fernung eines noch verbliebenen Chloratoms her stellbar.
Sie eignen sich vorzüglich als Wirkstoffe für Un krautbekämpfungsmittel, sowohl zur selektiven Ab tötung von Unkräutern unter Kulturpflanzen wie auch zur totalen Abtötung und Verhinderung uner wünschten Pflanzenwuchses. Unter Unkräutern wer den hierbei auch unerwünschte, z. B. vorher oder in der Nähe angebaute Kulturpflanzen verstanden. Die oben definierten Verbindungen eignen sich weiterhin auch als Wirkstoffe für andere hemmende Beeinflus sungen des Pflanzenwachstums, insbesondere Ent- blätterung, Reifebeschleunigung durch vorzeitiges Austrocknen, z. B. von Kartoffelstauden, ferner Ver minderung des Fruchtansatzes, Verzögerung der Blüte.
Als Wirkstoffe kommen zum Beispiel die nach stehenden Verbindungen in Frage: 2,4-Diäthoxy-6-äthylamino-s-triazin, F: 107-109 , 2,4-Diäthoxy-6-diäthylamino-s-triazin, F: 47,5-50,5 .
Zur Herstellung der erfindungsgemässen Mittel kommen Lösungsmittel, wie insbesondere Alkohole, z. B. Äthyl- oder Isopropylalkohol, Ketone, wie Aceton oder Cyclohexanon, aliphatische Kohlen wasserstoffe, wie Kerosen und cyclische Kohlen- wasserstoffe, wie Benzol, Toluol, Xylol, Tetrahydro- naphthalin, alkylierte Naphthaline, ferner chlorierte Kohlenwasserstoffe,
wie Tetrachloräthan, Äthylen chlorid und endlich auch mineralische und pflanzliche Öle oder Gemische der obgenannten Stoffe in Frage. Insbesondere bei der totalen Abtötung von Pflanzen wuchs, bei der vorzeitigen Austrocknung sowie der Entblätterung kann die Wirkung durch die Verwen dung von an sich phytotoxischen organischen Flüssig keiten, wie z. B. hochsiedenden Mineralölfraktionen oder Chlorkohlenwasserstoffen, verstärkt werden; anderseits kommt die Selektivität der Wachstums hemmung bei der Verwendung von gegenüber Pflan zen indifferenten Trägerstoffen, z.
B. in der selek tiven Unkrautbekämpfung unter Umständen deut licher zur Geltung.
Die verschiedenen Wirkstofflösungen können in üblicher Weise durch Zusatz von Stoffen, welche die Verteilung, die Haftfestigkeit, die Regenbeständigkeit und evtl. das Eindringungsvermögen verbessern, wie z. B. Fettsäuren oder Harzen, den Verwendungs zwecken näher angepasst werden. Ebenso lässt sich ihre biologische Wirkung verbreitern durch Zusatz von Stoffen mit bakteriziden Fungiziden oder eben- falls _das \Pflanzenwachstum beeinflussenden Eigen- sc'haften.
Gegenstand des vorliegenden Patentes ist ein Mit tel zur Beeinflussung des Pflanzenwachstums, insbe sondere zur Bekämpfung von Unkraut, dadurch ge kennzeichnet, dass es eine Verbindung der Formel
EMI0002.0005
worin X und Y Sauerstoff oder Schwefel, n 0 oder 1, R, R1 und R2 Wasserstoff oder Kohlenwasserstoffreste bedeuten, und eine organische Flüssigkeit enthält. <I>Beispiel 1</I> 5 Teile 2-Äthylamino-4,6-diäthoxy-s-triazin wer den in 90 Teilen flüssigen Trägerstoffes, z.
B. Tri- chloräthylen, Xylol, Aceton oder Diacetonalkohol, gelöst und mit 5 Teilen eines nichtionogenen Emulga- tors, z. B. Polyäthylenäther von Fettalkoholen, Alkyl- phenolpolyglykoläther, versetzt. Die Lösung wird im gewünschten Verhältnis mit Wasser vermischt und bildet eine milchige Emulsion.
<I>Beispiel 2</I> 10 Teile 2-Äthylamino-4,6-diäthoxy-s-triazin wer den in 90 Teilen Trichloräthylen oder in einer hoch- siedenden Flüssigkeit, wie z. B. Kohlenteeröl, Diesel öl oder Spindelöl, gelöst und direkt versprüht.
Means for influencing plant growth, in particular for combating weeds It has surprisingly been found that triazines of the formula
EMI0001.0004
where X and Y are oxygen or sulfur, n is 0 or 1, R, R1 and R2 are hydrogen or hydrocarbon residues, have a growth-inhibiting and killing effect on plants even in a very low concentration.
Compounds of the formula defined above can be prepared, for example, by reacting cyanuric chloride with suitable alcohols or mercaptans and amines, optionally followed by reductive removal of any remaining chlorine atom.
They are particularly suitable as active ingredients for weed control agents, both for the selective killing of weeds under cultivated plants and for the total killing and prevention of unwanted plant growth. Among weeds who the here also undesirable, z. B. understood previously or nearby crops grown. The compounds defined above are also suitable as active ingredients for other inhibitory influences on plant growth, in particular defoliation, acceleration of ripening through premature drying, eg. B. of potato plants, further reduction in fruit set, delay in flowering.
The following compounds, for example, can be used as active ingredients: 2,4-diethoxy-6-ethylamino-s-triazine, F: 107-109, 2,4-diethoxy-6-diethylamino-s-triazine, F: 47, 5-50.5.
Solvents, such as alcohols in particular, eg. B. ethyl or isopropyl alcohol, ketones such as acetone or cyclohexanone, aliphatic hydrocarbons such as kerosene and cyclic hydrocarbons such as benzene, toluene, xylene, tetrahydronaphthalene, alkylated naphthalenes, and also chlorinated hydrocarbons,
such as tetrachloroethane, ethylene chloride and finally also mineral and vegetable oils or mixtures of the above substances in question. In particular, in the total kill of plants grew, in the premature drying out and defoliation, the effect through the use of per se phytotoxic organic liquids such. B. high-boiling mineral oil fractions or chlorinated hydrocarbons are strengthened; on the other hand, the selectivity of the growth inhibition comes with the use of plants indifferent to plants such.
B. in selective weed control may be more effective.
The various active ingredient solutions can be added in the usual way by adding substances which improve the distribution, the adhesive strength, the rain resistance and possibly the penetration capacity, such as. B. fatty acids or resins, the purposes of use can be adjusted more closely. Likewise, their biological effect can be broadened by adding substances with bactericidal fungicides or properties which also affect plant growth.
The subject of the present patent is a means of influencing plant growth, in particular special for combating weeds, characterized in that it is a compound of the formula
EMI0002.0005
wherein X and Y are oxygen or sulfur, n is 0 or 1, R, R1 and R2 are hydrogen or hydrocarbon radicals, and contains an organic liquid. <I> Example 1 </I> 5 parts of 2-ethylamino-4,6-diethoxy-s-triazine who in 90 parts of liquid carrier, z.
B. trichlorethylene, xylene, acetone or diacetone alcohol, dissolved and treated with 5 parts of a nonionic emulsifier, z. B. polyethylene ethers of fatty alcohols, alkyl phenol polyglycol ethers, added. The solution is mixed with water in the desired ratio and forms a milky emulsion.
<I> Example 2 </I> 10 parts of 2-ethylamino-4,6-diethoxy-s-triazine who in 90 parts of trichlorethylene or in a high-boiling liquid, such as. B. coal tar oil, diesel oil or spindle oil, dissolved and sprayed directly.
