What is claimed is: 
     
         1 . Polymer composite material with biocide functionality comprising at least one base polymer compound and at least one biocide active ingredient, wherein the biocide active ingredient comprises an organic biocide that can be emitted from the polymer composite material by diffusion and/or osmosis. 
     
     
         2 . Polymer composite material according to  claim 1 , wherein the biocide active ingredient is incorporated in the polymer composite material as a molecular dispersion. 
     
     
         3 . Polymer composite material according to  claim 1 , wherein the polymer composite material comprises at least one base polymer compound with at least one coating layer and wherein the at least one coating layer comprises at least one biocide active ingredient. 
     
     
         4 . Polymer composite material according to  claim 3 , wherein the at least one base polymer compound comprises different coating layers, wherein some layers comprise the same biocide active ingredient or different biocide active ingredients. 
     
     
         5 . Polymer composite material according to  claim 1 , wherein the organic biocide is at least one selected from the group consisting of pesticides, herbicides, insecticides, algicides, fungicides, moluscicides, miticides, rodenticides, germicides, antibiotics, antibacterials, antivirals, antifungals, antiseptics, antiprotozoals, antiparasites, antiseptics, and disinfectants. 
     
     
         6 . Polymer composite material according to  claim 3 , wherein the coating layer has a water uptake of at least 100% over a coating layer area. 
     
     
         7 . Polymer composite material according to  claim 3 , wherein the at least one coating layer comprises at least one binder. 
     
     
         8 . Polymer composite material according to  claim 3 , wherein said at least one coating layer comprises gelatin. 
     
     
         9 . Polymer composite material according to  claim 3 , wherein said at least one coating layer comprises at least one additive. 
     
     
         10 . Polymer composite material according to  claim 3 , wherein the at least one coating layer comprises at least one carrier fluid. 
     
     
         11 . A method for the production of a polymer composite material comprising
 mixing at least one base polymer compound and at least one biocide active ingredient so that the biocide active ingredient is incorporated in a form of a molecular dispersion,   forming the polymer composite material in desired shape by molding and/or by film formation.   
     
     
         12 . Method for the production of a polymer composite material comprising
 mixing at least one coating compound and at least one biocide active ingredient so that the biocide active ingredient is incorporated, in a form of a molecular dispersion, and to form a first product,   coating a base polymer compound with the first product and curing the first product to form a coating layer on said base polymer.   
     
     
         13 . A Method according to  claim 12  wherein the method further comprises coating the base polymer compound on at least two sides thereof, and wherein the at least one biocide active ingredient is different on each side of said base polymer compound and/or the at least one coating compound is different on each side of said base polymer. 
     
     
         14 . A method according to  claim 11 , adapted for use in agriculture and/or horticulture. 
     
     
         15 . A method as claimed in  claim 14 , wherein said use in agriculture and/or horticulture comprises use as mulch film, fumigation film, propagation film, propagation pots, nursery trays and/or harvest trays. 
     
     
         16 . Mulch film, fumigation film, propagation film, propagation pots, nursery trays and/or harvest trays comprising a polymer composite material according to  claim 1 . 
     
     
         17 . A material of  claim 7 , wherein said binder is cross-linkable, and after said binder is cross-linked, said binder is water absorbing and/or gel forming. 
     
     
         18 . A material of  claim 9 , wherein said additive comprises a hardener. 
     
     
         19 . A material of  claim 10 , wherein said fluid comprises water and/or an organic solvent. 
     
     
         20 . A material of  claim 4 , wherein said at least one coating layer comprises water.
