WO 2004/096920 PCT/AU2004/000422 COLORANT FOR FOLLIAGE OF HUMID AND/OR FULVIC ACID, AND DYE FIELD OF THE INVENTION The present invention relates to a colorant composition. In particular, the present invention relates to a colorant composition suitable for colouring foliage 5 and in particular turf grass. Although the present invention will be described with particular reference to this application, it will be appreciated that the composition may find other applications and no limitation is intended thereby. BACKGROUND OF THE INVENTION Turf grasses are widely used in recreational areas, parks, golf courses, 10 bowling greens, athletic fields and domestic lawns. There is a demand for turf to have a uniform green colour so as to provide a pleasing appearance. This is particularly so for televised sporting events where it is desirable that a playing field have a healthy looking and uniform green colour. However, under adverse conditions such as drought and frosts, grass can lose its natural colour and in 15 some circumstances change to an undesirable appearance. Turf colorants that can impart a green colour to discoloured turf have been developed with a view to artificially returning a playing field to a desirable colour or to simply make the turf appear more robust and healthy. Green colorants are also used to colour sand and in particular, divot sand as used on golf courses. 20 A green colorant that is widely used commercially is a pigment based colorant comprising a water insoluble pigment suspended in an aqueous solution. In practice, application problems may be experienced when applying pigment based colorants. Such problems include blockage of application nozzles and equipment cleaning difficulties. 25 Other colorants for use in the agricultural industry are also available. Such colorants are based on water soluble dyes. As the dyes are water soluble, the above-mentioned application difficulties associated with pigment based colorants are generally not experienced. The dye based colorants typically contain blue or red dyes and are used as markers for spraying herbicides, insecticides and the 30 like. Blue colorants are also used to impart a blue colour to water features. The blue dyes may also be used on turf but impart a blue colour, which is generally not considered desirable.
WO 2004/096920 PCT/AU2004/000422 2 However, there are some concerns regarding repeated use of pigments on playing fields and the like for a number of reasons. First, there are potential toxicity problems to those spraying the dyes and those playing on, or otherwise using the field. Although pigments commonly used to colour turf are considered 5 safe to human health, there are few, if any, studies on long term exposure of these chemicals. Still further, there may be potential environmental hazards associated with build up of these chemicals in the environment as a result of repeated spraying. Generally a respray is necessary whenever the grass is cut. In some cases, a playing field may be sprayed at weekly or fortnightly intervals 10 immediately prior a match or game being played on the field. It is therefore an object of the present invention to provide an alternative colorant composition that is suitable for use on turf or other suitable surfaces. DESCRIPTION OF THE INVENTION According to a first broad form of the invention there is provided a colorant 15 composition comprising humic acid, fulvic acid or a mixture thereof and a water soluble dye. The present inventor has surprisingly and unexpectedly discovered that by adding humic and/or fulvic acid to a colorant, the colour of the resulting composition may be intensified and/or modified. 20 Humic acids are the fraction of humic substances that are not soluble in water under acidic conditions (less than about 2) but are soluble at higher pH values. Fulvic acids are soluble under all pH conditions. Humic acid and fulvic acid are typically available and used in the form of aqueous solutions. Alternatively, these materials are available in solid form such 25 as powder or granules. Typically, the composition is prepared by combining the ingredients with water to provide a concentrated liquid solution. This solution may be diluted prior to use. Alternatively, the components may be mixed in dry form. The dry mixture may be dissolved to provide a concentrate for shipping and sale, or may be dissolved prior to use. 30 Preferred dyes for use in the composition of the present invention are anionic dyes. Whilst not wishing to be bound by theory it is believed that the WO 2004/096920 PCT/AU2004/000422 3 anionic dyes are less likely to precipitate in the presence of anionic components of humic and/or fulvic acid salts. Especially preferred dyes are those containing organic acid groups, e.g., sulfonic, sulfamic, phosphoric, carboxylic, etc., or their salts. Acid dyes are 5 commonly alkali metal such as sodium or potassium, or ammonium salts of an organic acid. Preferred dyes are salts of sulfonic acids such as acid blue 62 (Sodium 1- amino- 4- (cyclohexylamino)- 9, 10- dihydro- 9, 10- dioxoanthracene 2- sulphonate); acid blue 74 (Disodium 5, 5'- (2- (1, 3- dihydro- 3- oxo- 2H indazol- 2- ylidene)- 1, 2- dihydro- 3H- indol- 3- one)disulphonate); acid blue 1 10 (Hydrogen [4- [4- (diethylamino)- 2', 4'- disulphonatobenzhydrylidene]cyclohexa 2, 5- dien- 1- ylidene]diethylammonium, sodium salt); acid blue 185 (CAS 1330 39-8); acid blue 9 (Dihydrogen (ethyl)[4- [4- [ethyl(3- sulphonatobenzyl)]amino] 2'- sulphonatobenzhydrylidene]cyclohexa- 2, 5- dien- 1- ylidene](3 sulphonatobenzyl)ammonium or disodium salt); acid green I (Trisodium tris[5, 6 15 dihydro- 5- (hydroxyimino)- 6- oxonaphthalene- 2- sulphonato(2- )- N5, 06]ferrate(3- ) and acid green 50 (Hydrogen [4- [4- (dimethylamino)- a- (2 hydroxy- 3, 6- disulphonato- 1- naphthyl)benzylidene]cyclohexa- 2, 5- dien- 1 ylidene]dimethylammonium, monosodium salt) or mixtures of any two or more thereof. Other suitable colouring agents are the phthalocyanine pigments of 20 which Copper phthalocyanine blue or Pigment blue 15 is an example. Especially preferred are the acid blue dyes, of which a sample is mentioned above. Such blue dyes are often used to impart a blue colour to ponds and water features. Blue dyes are also used as marker dyes to assist in identifying which areas of vegetation have been sprayed with a herbicide, 25 insecticide or the like. Blue dyes may also be used as bases for green colorants. A yellow dye such as tartrazine (acid yellow 23) may be combined with the blue to provide a desired green colour. It will be appreciated that any combination of two or more colorants may also be used in the composition of the present invention. The selection and 30 formulation of such colorants will depend upon the desired result. This may be determined by one of skill in the art.
WO 2004/096920 PCT/AU2004/000422 4 The present inventor has also very surprisingly and unexpectedly discovered that the combination of humic and/or fulvic acid with a blue dye produces a green colorant without requiring the addition of further yellow dyes or colouring agents. 5 The relative amounts of humic and/or fulvic acid to the colorant may be varied depending upon the desired colour and end use. Suitably the composition may comprise between about 50:1 to about 1:30, preferably between about 30:1 to about 1:3 parts by weight of humic and/or fulvic acid and colorant. Similarly, the actual amounts of dye and humic and/or fulvic acid in the composition may be 10 varied according to the nature of the dye, desired colour and end use. Suitably the composition is supplied in a concentrated form and diluted for application. Suitably a composition may include between about 10 to about 30wt% humic and/or fulvic acid. The composition may also include other one or more additives known in 15 the art such as stabilizers, stickers, surfactants or other surface active agents, fertilizers, insecticides, fungicides, pesticides, herbicides, wetting agents and the like. Preferably, the composition includes one or more fertilizers, typically one or more water soluble fertilizers. Suitable fertilizers, combinations and amounts 20 thereof are known in the art of horticulture and in particular, turf management. Suitable fertilizers include nitrogen sources such as urea, ammonia sulfate, urea formaldehyde; phosphate and potassium. A preferred fertilizer is urea. The composition may also include a source of iron in the form of iron sulfate or chelated iron such as ferric EDTA. 25 The composition may also include a surfactant that may assist the composition to adhere or stick to the grass. Surfactants suitable for such use include alcohol ethoxylates, nonyl, phenyl ethoxylates, polyethylene/polypropylene block copolymers. The present invention also relates to a method for imparting colour to 30 foliage. The foliage is typically turf grass but may be any other suitable foliage.
WO 2004/096920 PCT/AU2004/000422 5 According to a further broad form of the invention, there is provided a method of imparting a colour to foliage, the method including applying a composition of the first broad form to the foliage. The composition may be applied by any suitable means known in the art, 5 such as by spraying. By way of example only, the present invention will now be described with reference to the following Examples. A composition was prepared by mixing an aqueous solution of 120kg humic and/or fulvic acid (calculated as dry humic and/or fulvic acid) with 7.5kg of 10 a dye known as "Brilliant Blue" with 1000kg water. (It is believed that the brilliant blue contains the dye acid blue 9). The composition was sprayed onto a turf grass field at a rate of 0.2L - 1L per 1OOm 2 diluted in 2 - 40L water. This equates to about 24g to about 120 humic and/or fulvic acid per 100m and 1.5 to 7.5g dye. A preferred rate of application is 0.5-1L per 1OOm 2 diluted in 5-10L 15 water. A green colour was imparted to the field. A further composition was prepared in the same manner but with the further addition of 150kg urea and 35kg ferric EDTA to the 1000kg water. Comparative trials were conducted by using aqueous compositions comprising either humic and/or fulvic acid or dye on their own in the same amounts and 20 application rates as used above. In both cases, no visible green colour was imparted to the field. A further trial was conducted using a green paint conventionally used to colour a playing field. 90kg of the paint was diluted in 1000kg water before spraying as above. 25 It was observed that in the case of the composition of the invention and the commercially available green colorant, a green colour was imparted to the field. However, the composition of the invention achieved a similar colour intensity with significantly less colorant than that required using the conventional formulation. 30 Still further, it was surprisingly and unexpectedly observed that the composition of the invention imparted a green colour that was observed to be a far more natural colour and representative of a naturally green field. On the other WO 2004/096920 PCT/AU2004/000422 6 far more natural colour and representative of a naturally green field. On the other hand, the conventional green paint imparted a colour that was observed to be somewhat artificial as compared with a natural grass colour. The present inventor is unaware of a commercially available green turf colorant that imparts a 5 natural green colour. A further advantage of being able to impart a natural green colour to a field is that treated turf can more easily blend in with untreated turf. Such a situation may arise where there are patches of damaged turf to be repaired. Generally, with prior art compositions it is necessary to also spray untreated turf to provide a uniform green colour. This may not be necessary with 10 the preferred composition of the invention. Still further, the inventive composition was not observed to have any of the aforementioned application difficulties associated with the use of a pigment based colorant, i.e. clogging and/or blockage of applicator nozzles and the like. The present inventor is also unaware of a commercially available green turf 15 colorant that is based on a dye as opposed to a pigment. It may be seen that the composition of the present invention allows significantly less dye material to be used in order to impart a level of colour comparative to conventional formulations. This ability to decrease the levels of chemical colorants required can reduce potential health risks for workers 20 applying the chemicals, can reduce the build up of chemical residues in the environment and further, due to the decreased amount of colorant can reduce costs. (Humic and/or fulvic acid being less expensive than the available colorants). In the specification the term "comprising" shall be understood to have a 25 broad meaning similar to the term "including" and will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. This definition also applies to variations on the term "comprising" such as "comprise" and "comprises". 30 It will be appreciated that various changes and modifications may be made to the invention as described herein without departing from the spirit and scope thereof.
