1493293 8-Oxyquinolinate-metal-dimethyldithiocarbamate complexes ESZAKMAGYARORSZAGI VEGYIMUVEK and NOVENYVEDELMI KUTATO INTEZET 4 Dec 1975 [11 Dec 1974] 49804/75 Heading C2C The invention comprises complexes of general formula where M is a divalent metal atom, for example Mg, Mn, Fe, Ni, Cu, Zn, Cd or Sn. These complexes may be prepared by reacting an alkali metal salt of 8-hydroxyquinoline in an aqueous or other polar medium with an alkali metal salt of dimethyldithiocarbamic acid and a metal halide MX 2 where X is a halogen atom, e.g. chlorine; halides of two or more metals may be used, to obtain a mixture of complexes of the specified formula. The complexes have fungicidal and antibacterial properties, and also have a stimulating effect on plant growth.

tallov. They are filtered, washed and dried.
In this way, 8-hydroxyquinoline-2p-dimethyldithiocarbamate is obtained.
145 g (1 mol) of 8-hydroxyquinoline is added while stirring 40 g (1 mol) of sodium hydroxide in 1500 ml of methanol in a solution, stirred at room temperature until all of the substance goes into solution, and then 25% is added. an aqueous solution of 143 g (1 mol) sodium dimethyldithiocarbamate. At the temperature below, a solution of 136 g (1 mol of zinc chloride in 700 ml of methanol) is added to the homogeneous solution and the mixture is left to stand for a long time. The precipitated yellow precipitate is filtered off, washed with water and dried.
331 g (100% of theory) of a yellow crystalline substance is obtained which does not melt to 300 ° C and does not decompose.

Formulations for the use of preparations based on compounds of the formula I are ordinary: powders, granules, wettable powders, emulsions.
The content of the active substance in the preparations is from 10 to 80%.
The following examples illustrate the fungicidal and bacterial activity of the compounds according to the invention:
Example 1. In comparative studies, Alteirnaria tenuis u Botrytis cinerea was used as a control fungus.
The results of the experiments are attached to Table 1.

Example 2. The effectiveness of the complexes according to the invention, investigated on a very persistent pathogen Weizen-steinbrandes. Wheat seeds are etched with 8-hydroxyquinoline-Zn-dimethyldithiocarbamate. As a substance for comparison, an 80% dry remedy is used for pickling, which contains the known N-methyl-mercury (D) as active ingredient. -p-toluensulfonyl anilide (granozan). Wheat seeds are artificially infected with spores of TUte-tia caries and Ti B Eetia foo-tida ..- For etching, use 200 g of pickling agent per 100 kg of seed,
In order to establish the ratio of the development of spores, known methods 66, 50 69.0 are used.

Todas of grain imprints (KoruabdrucVesl) In Petri dishes, the nutrient medium is dried until its surface becomes cloudy.
The imprint obtained in this way is incubated at 12–18 ° C and on the 5.7th and 8th day the size of the imprint in which the spores developed is determined.
Simultaneously with the imprint experience, the grains are sowed and, as a control, untreated seeds are filled with garden soil in the boxes. Plant treatment results are examined by measuring the height of plants, conducted through
5 5 and 10 days after the appearance of seedlings. The results of the experiments are presented in table 2. Table 2
