Title: Novel materials and methods for the production thereof

Description:
The present invention relates to methods for the treatment of wallboards and building materials with fungicides and the treated wallboards and materials. In particular, the invention relates to the treatment of wallboards with a fungicidally effective amount of a synergistic composition comprising an anilinopyrimidine fungicide and another fungicide. More specifically the anilinopyrimidine fungicide is cyprodinil. 
     The fungi of relevance to the invention are those are those fungi which are capable of growing on building materials such as wallboards. Fungi are versatile organisms and the substrate on which they grow can include building materials since such materials can be made of, or have applied to them, substances which support fungal growth. Fungal growth generally requires dampness that can be caused on building materials by, for example, internal water leaks or external leaks, or by areas of high humidity or condensation. Fungal growth also requires a food source which, in this case, can be the building material itself or can be dirt or other nutritious material present on the building material. 
     Fungi which are capable of growing on building materials such as wallboards have been problematic for some time. Obvious effects of such fungi are discoloration of the material on which they grow, often accompanied by unpleasant smells. Fungi also contribute to the physical destruction of the material. In recent years, such fungi have also been an increasing cause for concern in relation to human health. Various health problems have been attributed to such fungi with most common being allergic reactions and in some cases, human infection. Certain fungi which are capable of growing on such building materials are also thought to be carcinogenic. Clearly these fungi are perceived as a growing threat to humans. 
     We have now found that certain fungicides, that were previously known for agricultural use, are surprisingly effective against fungi that are capable of growing on/infesting building materials such as wallboards. Agricultural use means application to crop plants or harvested agricultural products such as seeds. This invention represents a significant step forward in fungal control on building materials, in particular wallboards. 
     We have also identified that surprisingly cyprodinil synergises the activity of particular fungicides against certain fungi. More specifically, the addition of particular amounts of cyprodinil can powerfully increase the antifungal activity of particular fungicides against particular fungi that are deleterious to wallboards and building materials. 
     The present invention is also directed towards the provision of a composition having the following characteristics: (a) good efficacy against fungi which are capable of colonising and thus adversely affecting the technical integrity and/or cosmetic appearance of Building Materials; (b) exhibit good compatibility with the environment in which the Building Material is used; (c) can be formulated and manufactured in a cost effective way; and (d) are stable during use and storage for a reasonable period of time. 
     In addition to the above, in the light of environmental and governmental regulatory pressures, there is an increasing desire to reduce or eliminate certain compounds which are no longer acceptable for use in the treatment of materials. The present invention therefore seeks to provide, inter alia, an improved composition which does not contain any of the drawbacks of the compositions in the prior art. 
     According to the present invention there is provided a method for the prevention and/or treatment of growth and/or infestation of a fungus on a wallboard comprising treating said wallboard with a fungicidally effective amount of a synergistic composition comprising: (a) an anilinopyrimidine fungicide and (b) a fungicide selected from the group consisting of (b1) propiconazole; (b2) cyproconazole; (b3) difenoconazole; and (b4) thiabendazole. 
     Anilinopyrimidine fungicides are a class of agricultural fungicides. Cyprodinil is an example of an anilinopyrimidine fungicide. It is described in The Pesticide Manual, Thirteenth Edition, published by The British Crop Protection Council, 2003. Cyprodinil is entry 208 in The Pesticide Manual. 
     In a particular embodiment of the invention said anilinopyrimidine fungicide is cyprodinil. 
     In a further aspect of the invention there is provided a method for the prevention and/or treatment of fungal growth/infestation on a wallboard comprising treating said wallboard with a fungicidally effective amount of an anilinopyrimidine fungicide. In a particular embodiment said anilinopyrimidine fungicide is cyprodinil. 
     Wallboard (also sometimes known as drywall or plasterboard) is a building material commonly used to make the internal dividing walls of buildings. Buildings include residential buildings such as houses and flats and commercial buildings such as shops, warehouses, hotels and factories and the like, also institutional buildings such as colleges. Wallboard includes ceiling board which is material used for internal ceilings. Wallboard is generally in the form of a flat sheet between 0.5 and 2 cm thick and comprises, usually, a gypsum core, usually coated on both sides, with paper. Wallboard is usually fixed to a wooden frame to form an internal wall, or fixed to ceiling spars to form an internal ceiling. Wallboard has many desirable properties, such as being to relatively light and easy to cut, and having a surface that is easily decorated with paint or wallpaper. However, wallboard suffers from a particular problem if it is exposed to water and for that reason its use is restricted to internal areas of buildings. Gypsum is very water-absorbent, and once wet can take a long time to dry out. The combination of a damp gypsum core and the starch and cellulose in the paper on the surface provide an ideal substrate for fungi to grow. Essentially, the damp gypsum provides a convenient sustained water reservoir for the fungus while the paper provides nutrition. Even when used internally, wallboards can be exposed to water for example from leaky internal plumbing or from rainwater leaks from the outside of the building, or from sustained high humidity or condensation. Such leaks are unfortunately rather common and so fungal growth on wallboards is a continuing problem. 
     Fungi are at least in part responsible for so-called ‘black mould’, a fungal infestation of buildings. Wallboard is particularly susceptible to black mould, which has become a significant problem in buildings in some areas, and which has been blamed for a range of human health problems. Fungi are also responsible for facilitating discoloration of the material on which they grow and are a particular problem in residential buildings. 
     In a further aspect of the invention there is provided a method for the prevention and/or treatment of growth and/or infestation of a fungus on a wallboard comprising treating said wallboard with a fungicidally effective amount of a synergistic composition comprising: (a) cyprodinil and (b) a fungicide selected from the group consisting of (b1) propiconazole; (b2) cyproconazole; (b3) difenoconazole; and (b4) thiabendazole.

     In a still further aspect of the invention there is provided a method for treating a wallboard that has been previously treated with a different fungicide comprising applying to said wallboard a fungicidally effective amount of a synergistic composition as described above such that fungal contamination of said wallboard is prevented and/or retarded. 
     In a still further aspect of the invention there is provided a wallboard that has been treated with a synergistic composition comprising or consisting of cyprodinil and fludioxonil. 
     In a particular embodiment the wallboard comprises fungicides according to the invention present in concentrations of about 50 ppm to 1000 ppm. 
     The composition containing the fungicides according to the invention can be based on organic solvents or can be water based. Organic solvents can have the advantage of relatively quick drying, but water-based compositions are preferred because of their lower air pollution potential, and lower odour, particularly in buildings. One example of a suitable water-based composition is an emulsion concentrate. 
     The composition can be chosen from a number of formulation types, including dustable powders (DP), soluble powders (SP), water soluble granules (SG), water dispersible granules (WG), wettable powders (WP), granules (GR) (slow or fast release), soluble concentrates (SL), oil miscible liquids (OL), ultra low volume liquids (UL), emulsifiable concentrates (EC), dispersible concentrates (DC), emulsions (both oil in water (EW) and water in oil (EO)), micro-emulsions (ME), suspension concentrates (SC), aerosols, fogging/smoke formulations, capsule suspensions (CS) and other applicable formulations well known to the person skilled in the art. 
     Dustable powders (DP) may be prepared by mixing the fungicides according to the invention with one or more solid diluents (for example natural clays, kaolin, pyrophyllite, bentonite, alumina, montmorillonite, kieselguhr, chalk, diatomaceous earths, calcium phosphates, calcium and magnesium carbonates, sulphur, lime, flours, talc and other organic and inorganic solid carriers) and mechanically grinding the mixture to a fine powder. 
     Soluble powders (SP) may be prepared by mixing the fungicides with one or more water-soluble inorganic salts (such as sodium bicarbonate, sodium carbonate or magnesium sulphate) or one or more water-soluble organic solids (such as a polysaccharide) and, optionally, one or more wetting agents, one or more dispersing agents or a mixture of said agents to improve water dispersibility/solubility. The mixture is then ground to a fine powder. Similar compositions may also be granulated to form water-soluble granules (SG). 
     Wettable powders (WP) may be prepared by mixing the fungicides with one or more solid diluents or carriers, one or more wetting agents and, preferably, one or more dispersing agents and, optionally, one or more suspending agents to facilitate the dispersion in liquids. The mixture is then ground to a fine powder. Similar compositions may also be granulated to form water dispersible granules (WG). 
     Granules (GR) may be formed either by granulating a mixture of the fungicides according to the invention and one or more powdered solid diluents or carriers, or from pre-formed blank granules by absorbing the fungicides according to the invention (or a solution thereof, in a suitable agent) in a porous granular material (such as pumice, attapulgite clays, fuller&#39;s earth, kieselguhr, diatomaceous earths or ground corn cobs) or by adsorbing the fungicides according to the invention (or a solution thereof, in a suitable agent) on to a hard core material (such as sands, silicates, mineral carbonates, sulphates or phosphates) and drying if necessary. Agents which are commonly used to aid absorption or adsorption include solvents (such as aliphatic and aromatic petroleum solvents, alcohols, ethers, ketones and esters) and sticking agents (such as polyvinyl acetates, polyvinyl alcohols, dextrins, sugars and vegetable oils). One or more other additives may also be included in granules (for example an emulsifying agent, wetting agent or dispersing agent). 
     Dispersible Concentrates (DC) may be prepared by dissolving the fungicides according to the invention in water or an organic solvent, such as a ketone, alcohol or glycol ether. These solutions may contain a surface-active agent (for example to improve water dilution or prevent crystallisation in a spray tank). 
     Emulsifiable concentrates (EC) or oil-in-water emulsions (EW) may be prepared by dissolving the fungicides according to the invention in an organic solvent (optionally containing one or more wetting agents, one or more emulsifying agents or a mixture of said agents). Suitable organic solvents for use in ECs include aromatic hydrocarbons (such as alkylbenzenes or alkylnaphthalenes, exemplified by SOLVESSO 100, SOLVESSO 150 and SOLVESSO 200; SOLVESSO is a Registered Trade Mark), ketones (such as cyclohexanone or methylcyclohexanone), alcohols (such as benzyl alcohol, furfuryl alcohol or butanol), N-alkylpyrrolidones (such as N-methylpyrrolidone or N-octylpyrrolidone), dimethyl amides of fatty acids (such as C 8 -C 10  fatty acid dimethylamide) and chlorinated hydrocarbons. An EC product may spontaneously emulsify on addition to water, to produce an emulsion with sufficient stability to allow spray application through appropriate equipment. Preparation of an EW involves obtaining the fungicides according to the invention either as a liquid (if it is not a liquid at room temperature, it may be melted at a reasonable temperature, typically below 70° C.) or in solution (by dissolving it in an appropriate solvent) and then emulsifying the resultant liquid or solution into water containing one or more SFAs, under high shear, to produce an emulsion. Suitable solvents for use in EWs include vegetable oils, chlorinated hydrocarbons (such as chlorobenzenes), aromatic solvents (such as alkylbenzenes or alkylnaphthalenes) and other appropriate organic solvents that have low solubility in water. 
     Microemulsions (ME) may be prepared by mixing water with a blend of one or more solvents with one or more SFAs, to produce spontaneously a thermodynamically stable isotropic liquid formulation. The fungicides according to the invention are present initially in either the water or the solvent/SFA blend. Suitable solvents for use in MEs include those hereinbefore described for use in ECs or in EWs. An ME may be either an oil-in-water or a water-in-oil system (which system is present may be determined by conductivity measurements) and may be suitable for mixing water-soluble and oil-soluble pesticides in the same formulation. An ME is suitable for dilution into water, either remaining as a microemulsion or forming a conventional oil-in-water emulsion. 
     Suspension concentrates (SC) may comprise aqueous or non-aqueous suspensions of finely divided insoluble solid particles of the fungicides according to the invention. SCs may be prepared by ball or bead milling the fungicides according to the invention in a suitable medium, optionally with one or more dispersing agents, to produce a fine particle suspension of the compound. One or more wetting agents may be included in the composition and a suspending agent may be included to reduce the rate at which the particles settle. Alternatively the fungicides according to the invention may be dry milled and added to water, containing agents hereinbefore described, to produce the desired end product. 
     Aerosol formulations comprise the fungicides according to the invention and a suitable propellant (for example n-butane). The fungicides according to the invention may also be dissolved or dispersed in a suitable medium (for example water or a water miscible liquid, such as n-propanol) to provide compositions for use in non-pressurised, hand-actuated spray pumps. 
     The fungicides according to the invention may be mixed in the dry state with a pyrotechnic mixture to form a composition suitable for generating, in an enclosed space, a smoke containing the compound. 
     Capsule suspensions (CS) may be prepared in a manner similar to the preparation of EW formulations but with an additional polymerisation stage such that an aqueous dispersion of oil droplets is obtained, in which each oil droplet is encapsulated by a polymeric shell and contains a fungicide/fungicides according to the invention and, optionally, a carrier or diluent therefor. The polymeric shell may be produced by either an interfacial polycondensation reaction or by a coacervation procedure. The compositions may provide for controlled release of the fungicides according to the invention. The fungicides according to the invention may also be formulated in a biodegradable polymeric matrix to provide a slow, controlled release of the compound. 
     The composition may include one or more additives to improve the properties of the composition (for example by improving wetting, retention or distribution on surfaces; or absorption into surfaces). Such additives include surface-active agents, spray additives based on oils, for example certain mineral oils or natural plant oils (such as soy bean and rape seed oil), and blends of these with other bio-enhancing adjuvants (ingredients which may aid or modify the action of the fungicides according to the invention). 
     The Compositions of this invention may contain other compounds having biological activity, for example compounds having similar or complementary fungicidal activity or which possess, insecticidal and/or acaricidal and/or algicidal activity. The fungicide can also be combined with other fungicides. Combinations with other fungicides can be used to control a broader range of fungi, which is particularly useful if multiple species of fungi are present, or if the species is not known. 
     The addition of another active ingredient may provide a composition having a broader spectrum of activity or increased persistence at a locus, synergise the activity or complement the activity (for example by increasing the speed of effect or overcoming repellency) of the fungicides according to the invention, or help to overcome or prevent the development of resistance to individual components. 
     Examples of fungicidal compounds which may be included in the composition of the invention are AC 382042 (N-(1-cyano-1,2-dimethylpropyl)-2-(24-dichlorophenoxy) propionamide), acibenzolar-S-methyl, alanycarb, aldimorph, anilazine, azaconazole, azafenidin, benalaxyl, benomyl, benthiavalicarb, biloxazol, bitertanol, blasticidin S, boscalid (new name for nicobifen), bromuconazole, Bronopol, bupirimate, captafol, captan, carbendazim, carbendazim chlorhydrate, carboxin, carpropamid, carvone, CGA 41396, CGA 41397, chinomethionate, chlorbenzthiazone, chlorothalonil, chlorozolinate, clozylacon, copper containing compounds such as copper oxychloride copper oxyquinolate, copper sulphate, copper tallate, and Bordeaux mixture, cyamidazosulfamid, cyazofamid (IKF-916), cyflufenamid, cymoxanil, cyproconazole, debacarb, di-2-pyridyl disulphide 1,1′-dioxide, dichlofluanid, diclocymet, diclomezine, dicloran, diethofencarb, difenoconazole, difenzoquat, diflumetorim, diidomethyl-p-tolylsufone (Amical, from Dow) O,O-di-iso-propyl-S-benzyl thiophosphate, dimefluazole, dimetconazole, dimethirimol, dimethomorph, diniconazole, dinocap, dithianon, Dithiocarbamates, dodecyl dimethyl ammonium chloride, dodemorph, dodine, doguadine, edifenphos, epoxiconazole, ethaboxam, ethirimol, ethyl (2)-N-benzyl-N([methyl(methyl-thioethylideneaminooxycarbonyl)amino]thio)β-alanine, etridiazole, famoxadone, fenamidone, fenarimol, fenbuconazole, fenfuram, fenhexanid, fenoxanil (AC 382042), fenpropidin, fenpropimorph, fentin acetate, fentin hydroxide, ferbam, ferimzone, fluazinam, fludioxonil, flumetover, flumorph, fluoroimide, fluquinconazole, flusilazole, flusulfamide, flutolanil, flutriafol, folpet, fosetyl-aluminium, fuberidazole, furalaxyl, furametpyr, guazatine, hexaconazole, hydroxyisoxazole, hymexazole, imazalil, imibenconazole, iminoctadine, iminoctadine triacetate, 3-iodo-2-propynyl butylcarbamate (IBPC), ipconazole, iprobenfos, iprodione, iprovalicarb, isopropanyl butyl carbamate, isoprothiolane, kasugamycin, LY186054, LY211795, LY 248908, mancozeb, maneb, MBT mefenoxam, mepanipyrim, mepronil, metalaxyl, metalaxyl M, metconazole, metiram, metiram-zinc, metrafenone, MON65500 (N-allyl-4,5-dimethyl-2-trimethylsilylthiophene-3-carboxamide), myclobutanil, NTN0301, neoasozin, nickel dimethyldithiocarbamate, nitrothale-isopropyl, nuarimol, 2-O-octyl-4-isothiazolin-3-one (Skane M 8 Rohm &amp; Hass), ofurace, organomercury compounds, oxadixyl, oxasulfuron, oxolinic acid, oxpoconazole, oxycarboxin, pefurazoate, penconazole, pencycuron, phenazin oxide, phosphorus acids, phthalide, polyoxin D, polyram, probenazole, prochloraz, procymidone, propamocarb, propamocarb hydrochloride, propiconazole, propineb, propionic acid, proquinazid, prothioconazole, pyrazophos, Sodium and Zinc Pyrithione (Omadine chemistry from Arch Chem.), pyrifenox, pyrimethanil, pyroquilon, pyroxyfur, pyrrolnitrin, quaternary ammonium compounds, quinomethionate, quinoxyfen, quintozene, silthiofam (MON 65500), S-imazalil, simeconazole, sipconazole, sodium pentachlorophenate, spiroxamine, streptomycin, sulphur, tebuconazole, tecloftalam, tecnazene, tetraconazole, thifluzamide, 2-(thiocyano-methylthio)benzothiazole, thiophanate-methyl, thiram, tiadinil, timibenconazole, tolclofos-methyl, tolylfluanid, triadimefon, triadimenol, triazbutil, triazoxide, tricyclazole, tridemorph, triflumizole, triforine, triticonazole, validamycin A, vapam, vinclozolin, XRD-563, zineb, ziram, zoxamide and compounds of the formulae: 
     
       
         
         
             
             
         
       
     
     Some mixtures may comprise active ingredients that have significantly different physical, chemical or biological properties such that they do not easily lend themselves to the same conventional formulation type. In these circumstances other formulation types may be prepared. For example, where one active ingredient is a water insoluble solid and the other a water insoluble liquid, it may nevertheless be possible to disperse each active ingredient in the same continuous aqueous phase by dispersing the solid active ingredient as a suspension (using a preparation analogous to that of an SC) but dispersing the liquid active ingredient as an emulsion (using a preparation analogous to that of an EW). The resultant composition is a suspoemulsion (SE) formulation. 
     A dye can also be included in the compositions. This can be useful to differentiate treated wallboard from untreated wallboard. When the wallboard is new this provides a simple visual identifier for warehouse operators and construction workers. A dye can also be useful when the composition is applied to wallboard that has already been installed to identify those areas to which fungicide has been applied, for example when spraying a large area. It is useful for the applicators to see where they have applied the composition particularly when multiple operators are carrying out the application, or when the application process carried out over a number of days. It also allows easy inspection so that supervisors and surveyors can see what has been treated. It is also possible to use the depth of the colour as a guide to the amount of fungicide applied, particularly when it is applied to the wallboard surface. The depth of colour can be assessed visually, or a colorimeter can be used.

     Propagation of the Different Fungi: 
       Stachybotrys chartarum , and  Aureobasidium pullulans  were separately cultivated on PDA media to suppress sporulation. Spore suspensions were produced for each fungi. 
     Test method used: liquid culture assay on 24 well plates. 
     For solo (i.e. single) ai testing the formulated fungicide (100 ul) was filled into the 24 well plates (8 different rates: 100-0.05 mg ai/l final volume as described above) and 100 ul distilled water was added. Afterwards 800 ul of 0.3% PDA media was added to the plate. The spore suspension of the specific fungi was added to this media in advance containing approx. 100.000 spores/ml. The 24 well plates were sealed and incubated at 24° C. 
     Dependent on the growth prosperities of each organisms, the evaluation was done after 3 to 6 days, when the surface of the check well was covered with mycelium. The evaluation was performed by assessing the growth of the fungi related to the check growth. The results are expressed as % activity relative to the check (values of 0-100% growth). Afterwards the results were converted in % growth inhibition. EC95 values and also MIC (minimal inhibition concentration) values were derived for each compound. 
     Results 
     For each solo compound a graph was drawn of percentage inhibition against the concentration of the fungicide. From this graph the concentration of the fungicide required to achieve 95% activity was estimated. Also the concentration that gave the minimum inhibition concentration was derived as MIC value.

     Example 2 
     Synergy Testing 
     For synergism testing of the 2 way mixtures 100 ul of each fungicide were filled into the 24 well plates (8 different rates) and 800 ul of 0.3% PDA media containing the spore suspension was added (see above). Different ratios of the 2 fungicide rates were tested at the same time. 
     Propagation of the Different Fungi: 
       Stachybotrys chartarum  and  Aureobasidium pullulans  were separately cultivated on PDA media to suppress sporulation. Spore suspensions were produced for each fungi. 
     Analysis: 
     For the mixtures of different fungicides the synergism was calculated based on the Colby equation, which is described below: 
     A synergistic effect exists whenever the action of the active ingredient combination of the compound of formula I and one or more compounds of formula II is greater than the sum of the actions of the active ingredients applied individually. 
     The fungicidal action to be expected, We, for a given combination of two fungicides can be calculated as follows (see COLBY, S. R. “Calculating synergistic and antagonistic response of herbicide combinations”. Weeds 15, pages 20-22; 1967): 
         We=X+[Y ×(100 −X )/100] 
     wherein:
 
X=% activity in the case of treatment with the compound of formula I at rate x, in comparison with untreated control (=0%).
 
Y=% activity in the case of treatment with a compound of formula II at rate y, in comparison with untreated control.
 
We=expected activity (% activity in comparison with untreated control) after treatment with the compound of formula I and a compound of formula II at a rate of x+y kg of active ingredient.
 
     If the activity actually observed is greater than the expected value We, there is a synergistic effect. The synergistic effect of the combinations of the active ingredient of CDL with the active ingredients described above is demonstrated in the following results.
