Description

Characteristic of the known state of the art

Anthropogenic pollution pollutants and xenobiotics cause accelerated aging, growth losses and z.T. the mass death of the conifers. The manifold explanations for the damage of the forest stands by anthropogenic Noxen can be based on BLANK, L, Nature 314, 1985, 3111-314; GUDERIAN, R., Air pollution by photochemical oxidants, Springer Verlag 1985; B. HOCK and E. EISTNER, Plant Toxicology, Mannheim, Vienna, Zurich 1984; Jäger et al., Eur. J. For. Path. 16,1986,98-109; SCHENK et al. 1986, lecture Rhein.-Westf. AdW 1.10.86; MATSCHKE et al. 1988, Contrib. Forstw. 22, 1988, 125-133 so densify that after recording the pollutants and under the influence of light of the short-wave spectral range reactive oxygen species are formed in the protoplasts that initiate oxidations and peroxidation of Zellkomr onenten inadequate detoxification. Narli overexertion of the antioxidant potential of the cells in particular the lipoprotein complex is destroyed with subsequent co-oxidation of the pigments. In addition to biochemical changes as a result of destructuring of the biomembranes (B. HOCK and E. ELSTNER, Plant Toxicology, Mannheim, Vienna, Zütich, 1984) and pigments (Lichtenthaler, H., Naturwiss Rdschau 37, 1984, 297-297), disorders occur the energy metabolism, to impair the photosynthesis and the loss of nutrients, preferably magnesium (Küppers, M. Forstwiss, CbI., 104, 1985, 23-36). With the help of silviculture, breeding and revitalization measures, the forestry tries to initiate appropriate adaptation measures against the stock impairment. The application of minimum nutrients, for example calcium and magnesium, is in the foreground of interest (DE 3308183, DE 3314123, DE 3628611, DE 2730C19, DD 2760457), in addition to the use of heavy metals (OBUDJONNY, PT, Lesn. Chozj 1977, 35-38, DE 3151612) and thiocyanates (DE 3626875). To activate plant avoidance mechanisms, polymeric coating and adhesion preparations (DE 1495520, DE 2641173, DE 3314958, DE 3140897, US 44811254) in combination with absorbers of UV light were used to reduce the UV radiation and thus prevent the formation of damaging photooxidants. In order to increase the tolerance mechanisms of the plants to immissions, in addition to antioxidants cytokininanaloge connections in combination with Protektantien were administered (US 4032638, DE 2238053, DE 2341469, DD 2978875, DD 2764188, CARNAHAN, I. et al., Phytopath. 1978,1225- 1229; MOOI, I., Forst- u.

The large-scale application of the compounds and formulations described as effective, preferably polymeric coatings as protective substances with the addition of antioxidants, radical scavengers, pseudoperoxidases, cytokinins and nutrients is limited by their insufficient adhesion to the plants with conditional absorption or sufficient liability but insufficient absorption by the assimilation organs ,

Object of the invention

The aim of the invention is to counteract the loss of vitality caused by pollution pollutants and xenobiotics in Koniferen, early aging and death of forest stands.

Explanation of the essence of the invention

It is an object of the invention to provide an effective means for avoiding stress or reducing the stress on conifers against exposure to xenobiotics and imission components.

According to the invention the object is achieved by an agent containing in aqueous solution a combination of 0.01 to 1% gelatin and 0.01 to 0.5% bisazidostilbene disulfonic acid.

The aqueous solution may additionally contain active ingredients such as Cylok'nine, antioxidants, UV absorbers and nutrients.

The gelatin is not subject to any special requirements. All gelatins which are also used in the photographic and food industry as well as in the pharmaceutical industry are suitable.

The Bisazidostilbendisulfonsäure can be prepared according to Houben-Weyl, Methods of Organic Chemistry 1965,1013 S. 809-810. By means of the combination according to the invention, the agent adheres very well to the assimilation organs of the conifers by crosslinking after exposure to light. It has been found that the UV-absorbing combination gelatin-bisazide form swellable and gas-permeable films on the Assimilationsorganen and already without further additions immissions can be compensated to which the plants are exposed. The tolerance function of the assimilation organs can additionally be activated by various active substances such as cytokinins, antioxidants, UV absorbers and nutrients such as water-soluble essential nutrients such as magnet, iron, boron and nutrients such as magnesium, iron and boron in combination with the polymer to be crosslinked , When formulating these compounds, it is necessary to proceed in such a way that the components

1. active ingredients and nutrients dissolved in water with the addition of a nonionic surfactant with vorquollener, at least 2% ig diluted gelatin at 25-3O ⁰ C are mixed.

2. The addition of water-dissolved Bisazidostilbendisulfonsäure immediately before application. It must be noted that this total mixture is stored during application in storage containers, protected from exposure to light, or the components 1 and 2 are stored separately until use in order to avoid premature crosslinking. The conifers z. B. spruces are sprayed dripping wet with the combination according to the invention before budding.

Vortei, o are the good adhesion to the conifers, the swellability and gas permeability and thus absorption capacity of nutrients and active ingredients by the Assimilationsorgane the plants.

In order to test the combinations according to the invention with regard to their effect under pollution load, the spruce after treatment in the period April to December with the Immissionsgason sulfur dioxide (520pg / m ³ air and ozone jig / m ³ air) 8 hours per day and a total of 835 hours per year loaded. At the end of the exercise period, the vitality of the treated plants was assessed in comparison to untreated and untreated control plants by determining the reflectance of the needles and determining the expression of the isoenzymes of peroxidase in young and old needles.

The smaller the needle readings (in scale divisions) after remission measurement, the higher the vitality of the plants to be assessed.

This statement is qualified by the expression of the isoenzymes of peroxidase.
