Description
NUTRITIONAL MIXTURES WITH A HIGH AND INCREASED EFFICACY
The present invention relates to nutritional mixtures with a high and increased efficacy.
In particular, the present invention relates to nu- tritional mixtures which supply essential elements for preventing and correcting nutritional deficiencies in plants.
Even more specifically, it relates to nutritional mixtures which supply essential elements for use in agri- culture, for the prevention and treatment of physiological alterations or nutritional unbalances in plants.
It is known from literature ("Principles of plant nutrition" Konrad Mengel and Ernest A. Kirkby Ed. Kluvert Academic Publishers) that plants need 16 essential ele- ments for growth: three of thee essential nutrients (carbon, hydrogen and oxygen) are mainly extracted from the air and water, the remaining thirteen elements must be absorbed through the roots from the surrounding soil. They include: calcium, magnesium, sulfur, nitrogen, phos- phorous, potassium, iron, manganese, copper, zinc, molybdenum, chlorine and boron.
Each of these sixteen nutrients is indispensable for the growth, development and overall health of plants, even those commonly called microelements, i.e. those ele- ments of which only minimum quantities are necessary.
The Applicant has already found a new group of compositions which supply essential elements or nutritive substances vital for the prevention and treatment of deficiencies and for the overall development of plants, as described in Italian patent application MI2005A001269.
The Applicant has now surprisingly found that mixtures comprising compounds having general formula (I) , added to compositions which supply essential elements and/or with chelating-complexing molecules, currently present on the market for agricultural use, are much more capable of compensating for nutritional deficiencies, providing plants with all the essential elements they need in bioavailable form.
An object of the present invention therefore relates to a nutritional mixture comprising one or more compounds having general formula (I) , containing compositions which supply essential elements "A" and/or chelating-complexing molecules "B" , wherein the compounds having general formula (I), have the following general formula:
(I)
wherein: n represents a number ranging from 0 to 3 ;
Y represents an amine group (NH2) , or a carboxylic group (COOH) , or a ureic group (NHCONH2) , or a guanidine group (NHC (NH) NH2) ;
Z represents an OH group, or an NH group directly- bound to Q when Q has the meaning of a carbonyl group;
Q represents a hydrogen atom, a Ci-C4 acyl group or a carbonyl group directly bound to Z when Z has the mean- ing of NH.
Compositions which supply nutritive substances "A" refer to compositions supplying nutritive substances comprising one or more essential elements selected from potassium, iron, calcium, magnesium, manganese, copper, zinc, molybdenum, boron or nitrogen and copolymeric compounds containing acid functions, obtained by the co- polymerization of mono- or oligosaccharides with acids or their mono-unsaturated mono/polycarboxylic derivatives and/or with mono-unsaturated sulfonic acids and/or mono- unsaturated phosphonic acids, already described by the Applicant in Italian patent application MI2005A001269.
Chelating-complexing molecules "B" refer to chelating-complexing molecules containing one or more essential elements selected from potassium, iron, calcium, magne- sium, manganese, copper, zinc, molybdenum and boron, in
the form of salts or chelated with compounds which prolong persistence in the soil, preferably selected from ethylenediaminotetra-acetic acid (EDTA) , hydroxyethylene- diaminotriacetic acid (HEDTA) , diethylenediaminopenta- acetic acid (DTPA) , ethylenediamino-di- (o-hydroxy- phenyl) acetic acid (EDDHA), ethylenediamino-di- (o- hydroxy-4-sulfo-phenyl) acetic acid (EDDHSA), ethylenediamino-di- (o-hydroxy-4 -methyl-phenyl) acetic acid (EDDHMA), ammonium ligninsulfonate (LSA) , 4-thiazolidinecarboxylic acid (TCA) , N-acetyl-4-thiazolidinecarboxylic acid (ATCA) .
Said chelating-complexing molecules "B" , currently present on the market for agricultural use therefore supply essential elements in the form of salts or chelated with compounds which prolong their persistence in the soil .
Further examples of "B" are represented by essential elements salified with carboxylic acids of a natural origin, such as amino-acids or oligopeptides, obtained by the more or less forced hydrolysis of protein matrixes, or Ci0-Ci2 fatty acids, or biliary acids.
In particular, in the compositions suppliers of nutritive elements "A" , the mono-oligosaccharides are selected from glucose, saccharose, fructose, leucrose, palatinose, lactose, maltose, mannose, sorbitol, manni-
tol, gluconic acid, glucuronic acid, alkyl ethers, hy- droxyalkyls and carboxyalkyls of saccharides; unsaturated mono/polycarboxylic acids and their derivatives are selected from acrylic acid, methacrylic acid, maleic an- hydride, acrylamide, allylsulfonic acid, methallylsul- fonic acid, vinylsulfonic acid, vinylphosphonic acid. Again with reference to the compositions suppliers of nutritive elements "A" , examples of copolymeric compounds containing acid functions, obtained by the copolymeriza- tion of of mono- or oligosaccharides with acids or their mono-unsaturated mono/polycarboxylic derivatives and/or with mono-unsaturated sulfonic acids and/or mono- unsaturated phosphonic acids, are selected from copolymers obtained by the copolymerization of glucose and acrylic acid; fructose and acrylic acid; palatinose and acrylic acid; leucrose and acrylic acid; saccharose, acrylic acid and methallylsulfonate,- saccharose, acrylic acid, methallylsulfonate and acrylamide; saccharose, maleic anhydride, phosphorous acid and sodium hydrogen sulfite; or saccharose, maleic anhydride, iron ammonium sulfate (II) .
Although said compositions "A", i.e. said compositions suppliers of essential elements, and said chelating-complexing molecules "B" , have different chemical characteristics, when containing the compounds having
general formula (I), regardless of their chemical nature, they still exert the same function of increasing the nutritional efficacy which is object of the synergy described for the nutritional mixtures according to the present invention.
One of the main advantages of the mixtures, object of the present invention, comprising one or more compounds having general formula (I) , containing compositions which supply essential elements "A" and/or chelat- ing-complexing molecules "B" , with respect to the use of the compositions "A" alone or the chelating-complexing molecules "B" alone currently on the market, is their high synergy which allows an increased nutritional efficacy, allowing excellent agronomical results to be reached with a reduced treatment cost and a lower supply of the deficient element, thus optimising the specific nutritional requirement.
The excellent supply of essential elements and synergic effect obtained with the nutritional mixtures ac- cording to the present invention can, for example, be documented by an improved efficiency in the physiological processes (for example, chlorophyllian photosynthesis) and a considerable "starter" effect, affirmed by a greater crop growth with respect to both dimensions and growth rate.
More specifically, the nutritional mixtures comprising one or more compounds having general formula (I) , containing compositions which supply nutritional elements "A" claimed in Italian patent application MI2005A001269, object of the present invention, have a negligent environmental impact and an excellent toxicological profile, thanks to their chemical characteristics and high biode- gradability.
This allows their insertion in nutritional programs and, in particular, in integrated production programs, as the mixtures, object of the present invention, preserve the high selectivity of said compositions, suppliers of essential elements and their various administration possibilities by means of the most consolidated and most re- cent agronomical techniques such as fertirrigation and nutrirrigation.
A further object of the present invention relates to the use of said nutritional mixtures comprising one or more compounds having general formula (I) , containing compositions which supply essential elements "A" and/or chelating-complexing molecules "B" , wherein the compounds having general formula (I) , have the following general formula :
(D wherein: n represents a number ranging from 0 to 3; Y represents an amine group (NH2) , or a carboxylic group (COOH) , or a ureic group (NHCONH2) , or a guanidine group (NHC(NH)NH2) ;
Z represents an OH group, or an NH group directly- bound to Q when Q has the meaning of a carbonyl group; Q represents a hydrogen atom, a Cx-C4 acyl group or a carbonyl group directly bound to Z when Z has the meaning of NH, as nutritional products in agriculture for the prevention and treatment of physiological alterations or nutritional unbalances in plants.
More specifically, the Applicant has also found that the nutritional mixtures according to the present invention have an excellent compatibility with commercial cupric fungicidal products, such as for example, Kentan DF (copper hydroxide at 25%) , copper oxychloride, copper hydroxide, Airone (1:1 mixture of copper oxychloride: copper hydroxide), Bordeaux mixture (copper sulfate
neutralized with lime) , and with Carlit (mixture of Benalaxyl 2.5%, Fosetyl Aluminium 35%, Mancozeb 35%) and with those claimed in patent application MI 2001A002430.
Said mixtures, object of the present invention, can be obtained by mixing one or more compounds having general formula (I) with the compositions, suppliers of nutritional elements "A" , already described in Italian patent application MI2005A001269 or by mixing one or more of the compounds having general formula (I) with chelating- complexing molecules "B" , or by mixing one or more of the compounds having general formula (I) with the compositions "A" and with the chelating-complexing molecules "B" .
Alternatively, the nutritional mixtures according to the present invention can be obtained by the direct synthesis of compositions, suppliers of nutritional elements "A" and/or chelating-complexing molecules "B" in the presence of one or more compounds having general formula (I) - In these mixtures, according to the present invention, the ratio between the compounds having general formula (I) and the compositions, suppliers of nutritional elements "A" and/or chelating-complexing molecules "B" , preferably varies within the range of 0.01 to 3. Even more preferably, it ranges from 0.45 to 1.5.
The mixtures, object of the present invention, can be applied, for example, vegetables, fruit (pomaceous and drupaceous etc.), citrus fruits, vines, strawberries, kiwis, tobacco, legumes, cereals, floral and ornamental plants, nurseries, golf courses, sports fields, tree- lined areas, topsoil and lawns.
A further object of the present invention relates to a method for the prevention and treatment of physiological alterations or nutritional unbalances in plants and for increasing their resistance against external pathogen attacks by the application of a nutritional mixture comprising one or more compounds having general formula (I) containing compositions, suppliers of essential elements "A" and/or chelating-complexing molecules "B" . The quantity of mixture according to the present invention, to be applied for obtaining the desired effects can vary in relation to various factors, such as for example, the element or elements which are to be agronomi- cally applied, the crop to be nourished, the type of soil, the degree and nature of the deficiency, the climatic conditions, the application method, the formulation adopted.
This information can be easily obtained in technical literature, for example, in "Il programma di fitonutri- zione ragionata" - Nutex or in "Azoto, agricoltura, am-
biente" - Assofertilizzanti - Federchimica (1991) or in "Mineral nutritive" Agrotecnica (1989) .
For practical used in agriculture, the above mixtures can be used directly in the form of aqueous solu- tions and/or solid preparations, in relation to the essential elements, or as liquid or solid formulations containing said mixtures and other compounds capable of supplying nourishment to plants, or for modulating their physiological processes and also ensuring protection against phytopathogen agents or insects and other parasitic species, through direct biocide actions or by the induction of the specific innate defense responses of each crop.
Some examples of compounds having general formula (I) are provided for illustrative and non-limiting purposes of the present invention:
• allantoin (COMPOUND 1) ;
• citrulline (COMPOUND 2) ;
• arginine (COMPOUND 3) ; • ornitine (COMPOUND 4) ;
• aspartic acid (COMPOUND 5) ;
• glutamic acid (COMPOUND 6) .
The quantity of mixture which can be used for practical uses in agriculture, can range from 0.01 g to 20 g per square metre of agrarian soil.
The application of the aqueous solution or liquid or solid formulations can be effected either through the leaves or roots by burial or an injector spade, in fer- tirrigation also in terrains with an alkaline pH and, in particular and effectively, by means of micro- irrigation systems such as hoses and drippers.
Solid or liquid formulations can be used in the form of dry powders, wettable powders, emulsifiable concentrates, micro-emulsions, pastes, gelatins, granulates, microgranules, solutions, suspensions, etc.
Within the scope of the present invention, these liquid or solid formulations can consequently relate to said mixtures alone or said mixtures together with other compounds capable of nourishing plants, or modulating their physiological processes, as well as ensuring protection against phytopathogen agents or insects and other parasitic species, through direct biocide actions or by the induction of the specific innate defense responses of each crop. The selection of the type of mixture and for- mulation depends on the specific use.
The mixtures are prepared in the known way, for example, by diluting or dissolving the active substance with a solvent means and/or a solid diluent, optionally in the presence of surface-active agents. Solid diluents, or carriers, which can be used are,
for example: silica, kaolin, bentonite, talc, infusorial earth, dolomite, calcium carbonate, magnesia, chalk, clays, synthetic silicates, attapulgite, seppiolite.
Liquid diluents which can be adopted are, for exam- pie, water, aromatic or paraffinic organic solvents, alcohols, esters, ketones, amides.
Sodium salts, potassium salts, calcium salts, tri- ethanolamine salts of: alkylnaphthalenesulphonates, condensed alkylnaphthalenesulphonates, phenylsulphonates, polycarboxylates, alkylsulphosuccinates, sulphosucci- nates, alkylsulphates, ligninsulphates, polyethoxylated fatty alcohols, alkylarylsulphonates, polyethoxylated al- kylphenols, polyethoxylated esters of sorbitol, polypro- poxy polyethoxylates (block polymers) , can be used as surface-active agents.
The mixtures, object of the present invention, can also contain special additives for particular purposes, such as for example, antifreeze agents: propylene glycol, or adhesive agents, such as gum Arabic, polyvinyl alco- hoi, polyvinyl pyrrolidone, etc.
If necessary, it is possible to add other compatible active principles to the compositions such as, for example other fungicides, phytoregulators, antibiotics, herbicides, insecticides and fertilizers. The mixtures, object of the present invention, do in
fact have an excellent compatibility with commercial NPK fertilizing products (based on nitrogen, phosphorous and potassium) , allowing their simultaneous administration.
The following examples are provided for a better un- derstanding of the invention, which are for purely illustrative and non- limiting purposes of the present invention. EXAMPLE 1 Preparation of Polymer a. A mole of glucose is dissolved in a solution at 30% of sodium hydroxide under stirring at 00C. 0.07 moles of H2O2 are subsequently added, the temperature being maintained at 00C. 3 moles of acrylic acid are then added dropwise to the alkaline solution of sugar and hydrogen peroxide with a consequent increase in the temperature to about 75°C. The mixture is further heated to 85°C, triggering the exothermic reaction which brings the temperature to 1050C. As soon as the maximum temperature is reached, the reaction mixture is immediately cooled to 200C, obtaining an extremely viscous solution. The content of active substance in the solution is 48%, determined by acidification. EXAMPLE 2 Preparation of the supplier composition "A", comprising iron and POLYMER "a" (Composition WA"1) .
1.2 1 of NH4OH at 30% are added to an aqueous solution of 2 Kg of POLYMER "a" . The basic solution thus obtained is slowly added under vortical stirring, by means of a Turrax homogeniser, to the solution formed by the dissolution of 1.727 Kg of FeNH4 (SO4) 2*12H2O in 3 1 of H2O. The reaction mixture immediately becomes a reddish- brown colour, it then passes through a considerable den- sifying phase and finally redissolves and stabilizes in the form of a brown-coloured soluble compound. The mix- ture is left to rest for a night and is then brought to the desired volume with H2O up to the most suitable percentage concentration of iron. EXAMPLE 3 Preparation of the mixture comprising allantoin and the composition "A"l (Mixture 1)
60 g of allantoin (COMPOUND 1) are added to 1 1 of the composition "A"l at 3% of iron and the mixture is left under stirring at room temperature until the complete dissolution of the allantoin. The aqueous solution thus obtained is ready for agronomical use . EXAMPLE 4
Preparation of the mixture comprising citrulline and the composition "A"l (Mixture 2) 600 g of citrulline (COMPOUND 2) are added to 1 1 of
the composition "A"l at 3% of iron and the mixture is left under stirring at room temperature until the complete dissolution of the citrulline.
The aqueous solution thus obtained is ready for agronomical use . EXAMPLE 5
Preparation of the mixture comprising arginine and the composition "A"l (Mixture 3)

EXAMPLE 35 Efficacy test of ferric chlorosis on tobacco in sand.
Tobacco cultivar Brygth (first two real leaves) was transplanted in plastic glasses having a volume equal to
161 cm3, filled with 180 g of sand. After overcoming the transplant crisis, each thesis was treated with 20 ml of a solution of the compounds under examination (normalized with 3% of Fe) every 10 days (three applications) and maintained every three days with 20 ml of demineralized water. This quantity is calculated so that there is no overflow of liquids from the vase. The theses were placed in a greenhouse at a temperature of about 240C - 60-65% R. H. - 16H of light. 10 days after the last treatment, each thesis was visually assessed as leaf and/or root development and the chlorophyll content indexes (SPAD values) effected on the last three leaves (average of 5 surveys per leaf) , by means of a "Chlorophyll Meter - SPAD 502" Minolta instrument (results in Table 1) .
