Für diese genannten biologischen Systeme gibt es zahlreiche Bestrebungen, um diese mit chemischen Mitteln, Pflanzenextrakten und physikalischen Methoden gegen die schädigenden Einflüsse der UV-Strahlen des Sonnenlichtes zu schützen.For these biological systems mentioned there are numerous efforts to this with chemical agents, plant extracts and physical methods against the damaging effects of UV rays from sunlight protect.
Diese Aufgabe ist aber bisher höchst unvollkommen durch erfinderische Leistungen gelöst. Deshalb bedarf es weiterer erfinderischer Leistungen.So far, however, this task has been extremely imperfect through inventive Achievements solved. Therefore, further inventive achievements are required.
Die Verwendung von Ligninen, Ligninderivaten, Ligninsulfonsäuren und Ligninsul fonaten als UV-Schutzmittel im Pflanzenschutz ist nicht bekannt.The use of lignins, lignin derivatives, ligninsulfonic acids and ligninsul Phonaten as a UV protection agent in crop protection is not known.
Die Verwendung der genannten Mittel ist auch nicht bekannt zum Schutz von lichtempfindlichen Pflanzenschutzmittelwirkstoffen (z. B. Pyrethrumextrakte).The use of the means mentioned is also not known for the protection of light-sensitive active ingredients in crop protection products (e.g. pyrethrum extracts).
Die bezeichneten Substanzen sind auch keine zugelassenen UV-Schutzmittel im Bereich der Kosmetik (Sonnenschutzmittel) und der Medizin (medizinische Hautcrems).The specified substances are also not approved UV protection agents in the Cosmetics (sunscreen) and medicine (medical Skin creams).
Bekannt ist jedoch die Verwendung von Ligninen, Ligninderivaten, Ligninsulfon säuren und Ligninsulfonaten als Pflanzenstärkungsmittel.However, the use of lignins, lignin derivatives, lignin sulfone is known acids and lignin sulfonates as plant strengthening agents.
Bei dieser Verwendung geht es um die Induktion pflanzeneigener Abwehrkräfte zur Prophylaxe und Metaphylaxe von Infektionskrankheiten bei Pflanzen.This use is about the induction of plant defenses for the prophylaxis and metaphylaxis of infectious diseases in plants.
Hinsichtlich weiterer Details wird auf die Offenlegungsschrift DE 44 04 860 A1 beim Deutschen Patentamt verwiesen.With regard to further details, reference is made to published patent application DE 44 04 860 A1 referred to the German Patent Office.
Der Erfindung liegt die Aufgabe zugrunde Lignine, Ligninderivate, Ligninsulfon säuren und Ligninsulfonate als neuartige UV-Schutzmittel für biologische Systeme und lichtempfindliche Pflanzenschutzmittelwirkstoffe sowie lichtem pfindliche Pflanzenstärkungsmittel (bevorzugt Pflanzenextrakte) zu verwenden.The invention has for its object lignins, lignin derivatives, lignin sulfone acids and lignin sulfonates as novel UV protection agents for biological Systems and light-sensitive crop protection agents as well as light sensitive plant strengthening agents (preferably plant extracts).

Verwendet werden Mittel, wie sie bereits in der Offenlegungsschrift DE 44 04 860 A1 beim Deutschen Patentamt beschrieben sind. Means are used, as already described in the published patent application DE 44 04 860 A1 are described at the German Patent Office.
Darüber hinaus wird hinsichtlich der Charakterisierung der Mittel auf Ullmanns Enzyklopädie der technischen Chemie, 4. neubearbeitete und erweiterte Auflage, Band 16, Verlag Chemie GmbH Weinheim 1978 sowie VCH-Verlagsgesellschaft Weinheim 1990 verwiesen.In addition, with regard to the characterization of the means on Ullmanns Encyclopedia of Technical Chemistry, 4th revised and expanded edition, Volume 16, Verlag Chemie GmbH Weinheim 1978 and VCH publishing company Weinheim 1990 referenced.
Die bezeichneten Mittel absorbieren UV-Licht einer Wellenlänge von 205 nm bis 350 nm.The designated means absorb UV light with a wavelength of 205 nm to 350 nm.
Dadurch sind Lignine, Ligninderivate, Ligninsulfonsäuren und Ligninsulfonate als "UV-Breitbandfilter" für eine neue Verwendung im Pflanzenschutz einsetzbar.As a result, lignins, lignin derivatives, ligninsulfonic acids and ligninsulfonates are considered "UV broadband filter" can be used for a new use in crop protection.
Genannte Mittel absorbieren sowohl UV-A-Strahlung (400-320 nm), UV-B-Strahlung (320-285 nm) und UV-C-Strahlung (285-100 nm).Means mentioned absorb both UV-A radiation (400-320 nm), UV-B radiation (320-285 nm) and UV-C radiation (285-100 nm).
Diese UV-Breitband-Schutzwirkung schützt biologische Systeme und licht empfindliche Pflanzenextrakte (Pflanzenschutzmittel, Pflanzenstärkungsmittel) effektiv vor Wirkungsverlusten.This UV broadband protective effect protects biological systems and light sensitive plant extracts (plant protection agents, plant strengthening agents) effective against loss of effectiveness.
Eine weitere Wirkungssteigerung der bezeichneten Lignine, Ligninderivate, Ligninsulfonsäuren und Ligninsulfonate als UV-Schutzmittel im Pflanzenschutz wird erreicht, wenn sie als galenische Zubereitungsformen (Formulierungen) in Kombination mit Lipidextrakten, Ölen, Lecithinextrakten sowie Vitamin A-, C- und Vitamin E-haltigen Substanzen zur Anwendung kommen.A further increase in the effectiveness of the designated lignins, lignin derivatives, Ligninsulfonic acids and ligninsulfonates as UV protection agents in crop protection is achieved if it is in galenic formulations (formulations) in Combination with lipid extracts, oils, lecithin extracts and vitamin A, C and Substances containing vitamin E are used.
Die Anwendung der bezeichneten Mittel im Pflanzenschutz geschieht in der Weise, daß sie den "biologischen Systemen" zugesetzt und gemeinsam mit diesen appliziert werden.The use of the designated agents in crop protection takes place in the Way that they are added to the "biological systems" and together with these are applied.
Zweckmäßig ist weiterhin eine Behandlung der biologischen Systeme und licht empfindlichen Substanzen mit UV-Sonnenschutzmitteln unmittelbar nach ihrer Anwendung als "Nützlinge" oder "Pflanzenschutzmittel" im Pflanzenschutz, soweit sie nicht gemeinsam auf diesen ausgebracht werden können.It is also expedient to treat the biological systems and light sensitive substances with UV sunscreen immediately after their Use as "beneficial organisms" or "crop protection agents" in crop protection, as far as they cannot be applied together on this.
Eine kombinierte Ausbringung ist aber aus ökonomischen Gründen zu empfehlen und die spezifischen Verhältnisse der gemeinsamen Applikation müssen an jedes einzelne biologische System angepaßt werden.A combined application is recommended for economic reasons and the specific conditions of the common application must be addressed to each individual biological system can be adapted.
Der UV-Schutz von biologischen Systemen hat sehr große Bedeutung für den biologischen Pflanzenschutz im Bio-Baumwollanbau in Ägypten und anderen Ländern mit bedeutender Baumwollproduktion zur Gewinnung von Baumwolle, die nicht mit persistenten und giftigen Pestizid-Schadstoffen belastet sein soll.The UV protection of biological systems is very important for the biological crop protection in organic cotton cultivation in Egypt and others Countries with significant cotton production for cotton production, which should not be contaminated with persistent and toxic pesticide pollutants.
Bedeutende Baumwollschädlinge, wie
Significant cotton pests, like
- - Egytian cotton leaf worm (Spotoptera littoralis, Spotoptera exigua), - Egytian cotton leaf worm (Spotoptera littoralis, Spotoptera exigua),
-
- Black cut worms (Agrotis ipsilon, Agrotis segetum)
und andere schädigende Raupen,- Black cut worms (Agrotis ipsilon, Agrotis segetum)
and other harmful caterpillars,
können effektiv mit insektenpathogenen Viren (z. B. Polyhedrose-Viren) bekämpft werden.can be effectively combated with insect pathogenic viruses (e.g. polyhedrosis viruses) become.
Zu diesem Zweck wurden in experimentellen Untersuchungen Larven der genannten Baumwollschädlinge mit Virussuspensionen der genannten insekten pathogenen Viren infiziert. Dadurch erkranken die Baumwollschädlinge und sterben sehr schnell ab bevor sie nennenswerte Schäden an den Baumwoll kulturen verursachen können.For this purpose, larvae of the Cotton pests mentioned with virus suspensions of the insects mentioned pathogenic viruses infected. As a result, the cotton pests and die very quickly before they cause any significant damage to the cotton can cause cultures.
Polyhedrose-Viren sind aber UV-empfindlich und müssen daher mit UV-Schutzmitteln behandelt werden.However, polyhedrosis viruses are UV-sensitive and must therefore be included UV protection agents are treated.
Dies geschieht in der Weise, daß Lignine, Ligninderivate, Lingninsulfonsäuren oder Ligninsulfonate den Virussuspensionen als UV-Schutzmittel zugesetzt werden.This is done in such a way that lignins, lignin derivatives, lingnine sulfonic acids or lignin sulfonates added to the virus suspensions as UV protection agents become.
Die UV-Schutzmittel werden gemeinsam mit der Virussuspension ausgebracht, wobei die UV-Schutzmittel in dem Konzentrationsbereich von 0,01% bis 0,1% Wirkstoffgehalt angewendet werden.The UV protection agents are applied together with the virus suspension, the UV protection agents in the concentration range from 0.01% to 0.1% Active substance content can be applied.
In dieser Weise behandelte Polyhedrose-Viren zeigten bei intensiver UV-Bestrah lung eine wesentlich höhere Beständigkeit (Erhaltung der Infektiosität der Viren) und Wirkungsdauer als unbehandelte Virussuspensionen.Polyhedrosis viruses treated in this way showed intense UV radiation a much higher resistance (maintenance of the infectivity of the viruses) and duration of action as untreated virus suspensions.
Die Infektiositätsdauer der behandelten Virussuspensionen konnte bis um das 30-fache verlängert werden im Vergleich zu unbehandelten biologischen Material.The duration of infectivity of the treated virus suspensions could be up to Can be extended 30 times compared to untreated biological material.
Die UV-Schutzwirkung der beschriebenen Mittel gemäß Beispiel 1 schützt auch Granulose-Viren zur Bekämpfung des Apfelwicklers und des Schalenwicklers im Obstbau.The UV protection effect of the agents described in Example 1 also protects Granulosic viruses to combat apple wrappers and peel wrappers Fruit growing.
Lignine, Ligninderivate, Ligninsulfonsäuren und Ligninsulfonate eignen sich auch als effektive UV-Schutzmittel für lichtempfindliche Substanzen (z. B. Pyrethrum extrakte), die im Pflanzenschutz zur Anwendung kommen. Lignins, lignin derivatives, ligninsulfonic acids and ligninsulfonates are also suitable as an effective UV protection agent for light-sensitive substances (e.g. pyrethrum extracts) that are used in crop protection.
