Abstract

The present invention relates to novel applications of the known active substance fluoridone, as well as to mixtures with other known active substances to combat the growth of algae on paints, antifouling paints and other technical materials.

Description

Algicidal agents

The present application relates to new applications of the known active ingredient Fluridone, and also mixtures with other known active ingredients, for combating the algae growth of paints, antifouling paints and other technical materials

Fluridones

It is already known that fluridone can be used as a herbicide for combating undesirable growth of surface waters with aquatic plants and algae (see also DE-OS 2 537 753, US-PA 4,235,619). In order to be able to act in these media, a certain level of water solubility is necessary It is also known that fluridones show a certain leaching behavior in soil (see also Zandvoort, Neth J Agric. Sei 37, 257 (1989))

It has now been found, unexpectedly, that fluridones can also be used to combat the algae growth of paints, antifouling paints and other technical materials, and that the active ingredient is not washed out of this medium despite its water solubility and its known leaching behavior in soil

Because of the good algicidal activity, the compound according to the invention also acts against lichens. In combination with fungicides, this often shows a synergistic increase in the potency In addition, it was found that the effect of fluridones can be improved significantly, in some cases even synergistically, if other herbicides, algicides and / or material protection agents are added as a mixing partner

The algae to be controlled are prokaryotic algae

(Cyanophyta / blue-green algae) such as representatives from the subclass Coccogoneae and the subclass Hormogoneae

Examples - but not restrictive - are from the order Chroococcales species of the genera Synechococcus, Chroococcus, Gloeocapsa, Aphanocapsa,

Aphanothece, Microcystis and Meπsmopedia, from the orders Chamaesiphonales and Pleurocapsales species of the genera Chamaesiphon and Dermatocarpa, from the order Oscillatoπales species of the genera Phormidium, Schizothπx, Spiru na, Plectonix and Lyngbyoc Npa, from the order Nypotosta, Gostolotulaa, Gostolotulaa, Gostolotulaa, Gost, Nostra, Gostlotulaa, from the order Nyp, Scytonema, Anabaenopsis, Calothπx and Aulosira, from the

Order Stigonematatles called species of the genera Stigonema, Fischerella, Hapalosiphon and Mastigocladus

Furthermore, the compound according to the invention also shows good activity against eukaryotic representatives from the departments Heterocontophyta, Rhodophyta, Chlorophyta, Euglenophyta, Cryptophyta, Dinophyta and Haptophyta. Examples - but without being restrictive - are from the class Xanthophyceae of the genera Tπbonema and Vauche from the class Chrysophyceae species of the genera Chrysocapsa, Rhizochrysis, Cfhrysosphaera, Phaeothammon and Thallochrysis, from the class Phaeophyceae (brown algae) species of the genera Ectocarpus, Pylaiella,

Cutleπa, Zanardinia, Dictyota, Padina, Dictyopteπs, Laminaπa, Macrocystis, Lessoma, Nerocystis, Chorda, Alaπa, Fucus, Ascophyllum, Himanthalia, Sargassum, Cystoseira, Hahdrys, Pelvetia, Coccophorcea and Rhodophyea) from Durvilla d of the genera Porphyπdum, Bangia, Porphyra, Corallina, Lithothamnia, Lithophyllum, Rhodymama, Delesseπa, Gπnnellia, Platysiphoma, Polysiphonia, Ceramium, Plumaπa, from the class Chlorophyceae (green algae) species of the genera Chlorococcumi, Chloroma, Chlorella, Chloroma, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella, Chlorella Enteromorpha, Ulothπx, Trentepohlia, Apatococcus, Desmococcus, Cladophora, Siphonocladus, Valonia, Caulerpa, Bryopsis, Acetabulaπa, Halimeda and Tuna called

The media and technical materials to be treated with algicide are preferably wood preservative paints and glazes, plastic coatings, latices,

Adhesives, glue and textiles and in particular for interior and exterior emulsion paints and antifouling paints

Dispersion paints are understood to mean aqueous, alkaline paints based on polymer dispersions which serve as binders

Production of emulsion paints related to polymer dispersions include, for example, polyacrylates, styrene acrylates, polyvinyl acetate, polyvinyl propionate and polymers

Fluridone can be incorporated into the above-mentioned emulsion paints or in their starting products either directly, or in the form of formulations or mixtures

Antifouling paints generally consist of the components described in Ungerer, Chem Ind 37 (1985), 730-732 and Williams, Antifouling Marin Coatings 1973, Park

Ridge Noyes 1973

Examples of recognized binders in antifouling paints are polyvinyl chloride in a solvent system, chlorinated rubber in a solvent system, acrylic resins in a solvent system, especially in an aqueous system,

Vinyl chloride / vinyl acetate copolymer systems in the form of aqueous dispersions or in the form of organic solvent systems, butadiene / styrene rubbers, butadiene / acrylonitrile rubbers, butadiene / styrene / acrylonitrile rubbers, drying oils, such as linseed oil, asphalt and epoxy compounds, resin esters or modified hard resins in combination with tar or bitumen, small amounts of chlorinated rubber, chlorinated polypropylene and vinyl resins If appropriate, the antifouling agents also contain inorganic pigments, organic pigments or dyes, which are preferably insoluble in seawater. Furthermore, the antifouling agents can contain materials such as rosin. In the case of fluridones, these bring about a controlled release of the active ingredient or of the active substance combinations. The antifouling agents can also contain plasticizers, the theological Fluridones can be incorporated into the above-mentioned antifouling paints or into their starting products either directly or as a formulation / mixture. Fluridones can also be incorporated into self-polishing antifouling systems, such as, for example, in the combinations mentioned below

The fluridone can be converted into customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and very fine encapsulations in polymeric substances

These formulations or agents are prepared in a known manner, for example by mixing the fluridone with extenders, that is to say liquid solvents, pressurized liquefied gases and / or solid carriers, optionally using surface-active agents, that is to say emulsifiers and / or dispersants and / or Foaming agents In the case of the use of

Water as an extender, for example, organic solvents can also be used as auxiliary solvents. Essentially suitable liquid solvents are aromatics, such as xylene, toluene, alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chlorethylenes, or methylene chloride, aliphatic hydrocarbons, such as Cyclohexane or paraffins, eg petroleum fractions, alcohols, such as butanol or glycol, and their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide or dimethyl sulfoxide, and water, with liquefied gaseous extenders or Carriers are liquids that are gaseous at normal temperature and pressure, e.g. aerosol propellants, such as halogenated hydrocarbons as well as butane, propane, nitrogen and carbon dioxide; solid carriers include natural rock powders such as kaoli ne, clays, talc, chalk, quartz, attapulgite, Montmorillonite or diatomaceous earth and synthetic rock flours, such as highly disperse silica, aluminum oxide and silicates, as solid carrier materials for granules, e.g. broken and fractionated natural rocks such as calcite, marble, pumice, sepiolite, dolomite as well as synthetic granules from inorganic and organic flours as well as granules organic material like sawdust,

Coconut shells, corn cobs and tobacco stalks are suitable as emulsifiers and / or foam-generating agents, for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulfonates, alkylsulfates, arylsulfonates and protein Dispersants are suitable, for example, lignin sulfite liquor and methyl cellulose

Adhesives such as carboxymethyl cellulose, natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol, polyvinyl acetate, and natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable Be Ole

Dyes such as inorganic pigments, for example iron oxide, titanium oxide, ferrocyan blue and organic dyes such as alizarin, azo and metal phthalocyanine dyes and trace nutrients such as salts of iron, manganese, boron, copper, cobalt,

Molybdenum and zinc can be used

The effectiveness against algae and the spectrum of activity of the fluridone or formulations produced from it is increased even further if further algicidal compounds, fungicides, bactericides, molluscicides, insecticides and / or

Antifouling agents are added. The mixtures have a broader spectrum of activity than fluridones alone

The weight ratios of the active ingredients in these active ingredient combinations can be varied within relatively large ranges.

The active compound combinations preferably contain 0.1 to 99.9% of the fluridone, in particular 1 to 75%, particularly preferably 5 to 50%, the

The rest is filled 100% by one or more of the above mentioned mixing partners.

A concentrate that can be used to protect emulsion paints, antifouling paints and other technical materials against algae contains the fluridone or the

Active ingredient combination in a concentration of 0.01 to 95% by weight, in particular 0.1 to 60% by weight.

The application concentrations of the fluridone or the active ingredient combinations depend on the type and occurrence of the algae to be controlled and on the composition of the color to be protected. The optimal amount can be determined by test series. In general, the application concentrations are in the range from 0.001 to 5% by weight, preferably from 0.05 to 1.0% by weight, based on the color to be protected.

The following examples are intended to illustrate the use of fluridones as aleicides: Examples

Example I

0.5% fluridones are incorporated into an exterior emulsion paint based on styrene acrylate. The paint containing fluridone is then spread on both sides of cardboard.

The test specimen is contaminated by immersion in an algae suspension of Phormidium, Oscillatoria, Chlorella and Scenedesmus species and placed on petri dishes filled with Allen's agar and inoculated with the algae mentioned.

After 4 weeks of incubation at room temperature and 1 200-1 500 LUX, the fluridone-containing plate showed very good algae resistance, while an active ingredient-free control of test organisms is completely covered.
