Campo da Invenção Field of the Invention
[001] A presente invenção versa sobre uma nova composição fertilizante com propriedade adjuvante que permite maior estabilidade entre misturas de tanque podendo ser utilizada juntamente com herbicidas e outros micro/macronutrientes. Esta invenção também descreve o uso desta composição. [001] The present invention relates to a novel adjuvant fertilising composition which allows for greater stability between tank mixtures and may be used in conjunction with herbicides and other micro / macronutrients. This invention also describes the use of this composition.
Antecedentes da Invenção Background of the Invention
[002] A necessidade do uso de fertilizantes na agricultura é essencial para o aumento da produtividade das culturas e para garantir a produção de alimentos em vista do crescimento da população mundial. Os principais elementos que compõem as composições de fertilizantes são divididos em dois principais grupos: os componentes minerais e não minerais. [002] The need for fertilizer use in agriculture is essential for increasing crop productivity and ensuring food production in view of world population growth. The main elements that make up fertilizer compositions are divided into two main groups: the mineral and non-mineral components.
[003] Os componentes não minerais são geralmente compostos por hidrogénio, oxigénio e carbono. Os nutrientes minerais são divididos em macronutrientes e micronutrientes. Os componentes de nitrogénio (N), fósforo (P), potássio (K), cálcio (Ca), magnésio (Mg) e enxofre (S) são nomeados de macronutrientes. Já como micronutrientes mais comuns destacam-se manganês (Mn), boro (B), cobalto (Co), molibdênio (Mo), níquel (Ni), silício (Si), zinco (Zn) entre outros. Non-mineral components are generally composed of hydrogen, oxygen and carbon. Mineral nutrients are divided into macronutrients and micronutrients. Nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) components are named macronutrients. Already the most common micronutrients stand out manganese (Mn), boron (B), cobalt (Co), molybdenum (Mo), nickel (Ni), silicon (Si), zinc (Zn) among others.
[004] Como fonte de nitrogénio podemos citar: uréia, sulfato de amónio, nitrato de potássio, monofosfato de amónio e difosfato de amónio providos dos seus respectivos ácidos. Para o fornecimento de fósforo, diferentes fontes podem ser utilizadas, como, por exemplo, os ácidos fosfóricos ou polifosf atados. Já o potássio geralmente provém do cloreto de potássio KC1 (60 a 62% de K2O e 48% de Cl), o sulfato de potássio K2SO4 (50 a 53% de K2O e 17% de S), o nitrato de potássio KNO3 (44 a 46% de K2O
e 13 a 14% de N) e o sulfato de potássio e magnésio K2S04.2MgS04 (22% de K20, 22% de S e l2 a l8% de Mg). Dentre essas fontes, o KC1 representa maior parte do mercado, aproximadamente 95% de todo o potássio usado na agricultura. [004] As a source of nitrogen we can cite: urea, ammonium sulfate, potassium nitrate, ammonium monophosphate and ammonium diphosphate with their respective acids. For the supply of phosphorus, different sources may be used, such as phosphoric acids or polyphosphates. Potassium usually comes from potassium chloride KCl (60 to 62% K 2 O and 48% Cl), potassium sulfate K 2 SO 4 (50 to 53% K 2 O and 17% S), potassium nitrate KNO 3 (44 to 46% K 2 O and 13 to 14% N) and potassium sulfate and magnesium .2MgS0 K2S0 4 4 (22% K 2 0, 22% S and l2 to l8% Mg). Among these sources, KC1 represents the largest share of the market, approximately 95% of all potassium used in agriculture.
[005] Geralmente os micro/macronutrientes são utilizados associados a misturas de defensivo agrícolas em uma única aplicação, visando otimizar tempo, mão de obra, ampliar o espectro de atuação e nutrir o solo/planta. Devido às grandes possibilidades de preparo de caldas de pulverização, a formação de misturas incompatíveis pode levar a precipitação de sólidos insolúveis, resultando posteriormente em problemas como decantação no tanque, entupimento de filtros e bicos e aplicação não uniforme. Micro / macronutrients are generally used in combination with pesticide mixtures in a single application to optimize time, labor, broaden the spectrum of action and nourish the soil / plant. Due to the large possibilities for spray mix preparation, the formation of incompatible mixtures can lead to precipitation of insoluble solids, resulting in problems such as tank settling, filter and nozzle clogging and non-uniform application.
[006] Entre os herbicidas usados para o combate a ervas daninhas, o mais utilizado é a n-fosfometilglicina, mais conhecido como glifosato. Devido à sua baixa toxicidade, alta eficácia em uma grande gama de espécies de pragas e fácil obtenção e síntese, o glifosato rapidamente se popularizou no mercado. Outro herbicida amplamente utilizado é o 2,4-ácido diclorofenoxiacético (2,4-D). Os sais desses herbicidas são normalmente preparados através da neutralização do ácido com bases orgânicas, como por exemplo, isopropilamina, dimetilamina, entre outras. Já os sais de glifosato frequentemente utilizados são monoisopropilamina (MIPA), hidróxido de potássio (KOH), amónia (NH3), monoetanolamina (MEA), trietanolamina (TEA) ou misturas dessas, a fim de se tornar solúvel em água. Among the herbicides used for weed control, the most commonly used is n-phosphomethylglycine, better known as glyphosate. Due to its low toxicity, high efficacy in a wide range of pest species and easy obtaining and synthesis, glyphosate has quickly become popular in the market. Another widely used herbicide is 2,4-dichlorophenoxyacetic acid (2,4-D). Salts of such herbicides are usually prepared by neutralizing the acid with organic bases such as isopropylamine, dimethylamine, among others. The frequently used glyphosate salts are monoisopropylamine (MIPA), potassium hydroxide (KOH), ammonia (NH 3 ), monoethanolamine (MEA), triethanolamine (TEA) or mixtures thereof in order to become water soluble.
[007] É conhecido que caldas de pulverização que contenham misturas de cátions de metais ou metais alcalinos terrosos, 2,4-D e glifosato geralmente geram problemas de precipitação e, consequentemente, afetam a aplicação. [007] It is known that spray mixtures containing cation mixtures of metal or alkaline earth metals, 2,4-D and glyphosate generally cause precipitation problems and, consequently, affect application.
[008] Devido a este problema, é muito comum que composições com 2,4-D já contenham adjuvantes em sua composição com o objetivo de
evitar problemas de incompatibilidade. Due to this problem, it is very common that compositions with 2,4-D already contain adjuvants in their composition for the purpose of avoid incompatibility issues.
[009] Como exemplo, pode-se citar a publicação WO As an example, mention may be made of WO
2008/069826A1 que relata uma formulação de herbicida com adjuvantes visando reduzir os problemas de incompatibilidade existente entre glifosato e 2,4-D. Já a publicação WO 2012/027349A1 descreve o desenvolvimento de uma formulação de 2,4-D contendo polietilenoamina e/ou polivinilamina como inibidores de cristalização para misturas com cátions presentes em fertilizantes. 2008 / 069826A1 reporting an adjuvanted herbicide formulation aimed at reducing the incompatibility problems between glyphosate and 2,4-D. WO 2012 / 027349A1 describes the development of a 2,4-D formulation containing polyethylene amine and / or polyvinyl amine as crystallization inhibitors for cation mixtures present in fertilizers.
[0010] No entanto, a utilização de herbicidas com adjuvantes compatibilizantes já presentes em sua composição limita a possibilidade de misturas, uma vez que, neste caso, a ordem de adição dos produtos pode alterar o resultado final. O desenvolvimento de uma solução para ser adicionada diretamente na calda de pulverização possibilitará o ajuste da dosagem de acordo com a complexidade da mistura, permitindo assim maior número de combinações. Assim, a Requerente desenvolveu uma composição fertilizante que poderá ser adicionado na calda de pulverização na proporção de 0,1-2,0 %, dependendo da complexibilidade da calda. However, the use of herbicides with compatibilizing adjuvants already present in their composition limits the possibility of mixtures, since in this case the order of addition of the products may alter the final result. The development of a solution to be added directly to the spray solution will allow the dosage to be adjusted according to the complexity of the mixture, thus allowing a greater number of combinations. Thus, the Applicant has developed a fertilizer composition which may be added to the spray solution at a rate of 0.1-2.0%, depending on the complexity of the spray solution.
[0011] E conhecido também a utilização de sulfato de amónio como condicionante de água para misturas contendo glifosato, 2,4-D e Dicamba. Neste caso, os ânions sulfatos atuam competindo com o glifosato pelos cátions da água dura, assim reduzindo a possibilidade de formação de espécies insolúveis de glifosato. No entanto, sabe-se que a utilização de sulfato de amónio em caldas promove o aumento da volatilização do Dicamba, proporcionando perdas do ingrediente ativo durante a aplicação. Assim, a busca por condicionantes de água alternativos tem-se mostrado o foco de muitas empresas detentoras de formulações envolvendo o ingrediente ativo Dicamba. The use of ammonium sulfate as a water conditioner for mixtures containing glyphosate, 2,4-D and Dicamba is also known. In this case, sulfate anions act by competing with glyphosate for hard water cations, thus reducing the possibility of formation of insoluble glyphosate species. However, it is known that the use of ammonium sulfate in syrups promotes increased volatility of Dicamba, providing losses of the active ingredient during application. Thus, the search for alternative water conditioners has been the focus of many companies holding formulations involving the active ingredient Dicamba.
[0012] A publicação WO2015/061873 ensina uma formulação de fertilizante contendo adjuvantes para caldas de baixo volume oleoso (BVO).
Esta composição compreende hidrocarbonetos alifáticos, ésteres de ácido graxo, misturas de surfactantes não iónicos e iónicos, compostos organosiliconados e agentes compatibilizantes visando à estabilidade de caldas. No entanto, sabe-se que a maioria dos produtos desenvolvidos atualmente ainda é destinada para a aplicação em calda aquosa, assim a solução proposta por este documento patentário limita a possibilidade de aplicações. Publication WO2015 / 061873 teaches a fertilizer formulation containing low oil volume syrup adjuvants (BVO). This composition comprises aliphatic hydrocarbons, fatty acid esters, mixtures of nonionic and ionic surfactants, organosiliconised compounds and compatibilizing agents for the stability of grout. However, it is known that most products currently developed are still intended for application in aqueous syrup, so the solution proposed by this patent document limits the possibility of applications.
[0013] Assim, verifica-se a necessidade de uma composição fertilizante que pode ser utilizada em misturas contendo micro/macronutrientes e herbicidas, como por exemplo glifosato e 2,4-D. Atualmente esses herbicidas representam o maior volume de vendas em herbicidas no mundo e devido suas características hidrofílicas são aplicados em caldas aquosas. Thus, there is a need for a fertilizer composition that can be used in mixtures containing micro / macronutrients and herbicides such as glyphosate and 2,4-D. Currently these herbicides represent the largest volume of herbicide sales in the world and due to their hydrophilic characteristics are applied in aqueous syrups.
[0014] Ainda, é importante obter um produto condicionante de água que permita a utilização de composições do tipo sais solúveis em águas com alto grau de dureza evitando a formação de sólidos indesejáveis durante a aplicação. Por fim, é desejado também encontrar uma composição que seja totalmente livre de nonilfenol e derivados, tornando-a uma solução condizente com as novas normas da legislação. Further, it is important to obtain a water conditioning product which allows the use of high hardness water soluble salt type compositions avoiding the formation of undesirable solids during application. Finally, it is also desired to find a composition that is completely free of nonylphenol and derivatives, making it a solution consistent with the new standards of the legislation.

EXEMPLO EXAMPLE
[0038] Durante o desenvolvimento da composição fertilizante, diversas combinações foram avaliadas a fim de encontrar a formulação mais eficiente para misturas de calda de pulverização. During the development of the fertilizer composition, various combinations were evaluated in order to find the most efficient formulation for spray mixtures.
[0039] Dessa forma, seguem-se os exemplos de duas composições de fertilizantes: Thus, here are the examples of two fertilizer compositions:
[0040] A composição fertilizante 1 compreende 27,0 % de amina graxa etoxilada, 12,5 % de álcool isodecílico fosfatado, 1,2 % de ácido fosfórico, 2,0 % de álcool isodecílico etoxilado, 27 % de éster de sorbitan etoxilado, 16 % de polietilenoglicol e 1 % de componentes siliconados.
[0041] A composição fertilizante 2 compreende 16,5 % de tristirilfenol etoxilado fosfatado, 1,0 % de ácido fosfórico, 27,0 % de éster de sorbitan etoxilado, 20,0 % e polietilenoglicol e 0,5 % de componentes siliconados. Fertilizer composition 1 comprises 27.0% ethoxylated grease amine, 12.5% phosphate isodecyl alcohol, 1.2% phosphoric acid, 2.0% ethoxylated isodecyl alcohol, 27% ethoxylated sorbitan ester , 16% polyethylene glycol and 1% silicone components. Fertilizer composition 2 comprises 16.5% phosphate ethoxylated tristirylphenol, 1.0% phosphoric acid, 27.0% ethoxylated sorbitan ester, 20.0% polyethylene glycol and 0.5% silicon components.
[0042] Em seguida, as composições fertilizantes foram testadas sob condições mais estressantes, a fim de avaliar o poder de estabilização das caldas. Os parâmetros variados foram: temperatura (5 °C, 25 °C), concentração do glifosato (1,5 kg/hec, 4,0 kg/hec), presença de manganês (sim, não) e presença de zinco e cobalto (sim, não). Subsequently, the fertilizer compositions were tested under more stressful conditions in order to evaluate the stabilizing power of the syrups. The varied parameters were: temperature (5 ° C, 25 ° C), glyphosate concentration (1.5 kg / hec, 4.0 kg / hec), presence of manganese (yes, no) and presence of zinc and cobalt ( Yes No).
[0043] As avaliações da estabilidade das caldas foram feitas visualmente e comparativamente. Quando não houve mudança significativa com a adição da composição, a nota foi zero. Quando houve melhorias com adição da composição, a nota foi 1. Quando a melhora foi significativa foi dado a nota 2. Assim, as melhores composições fertilizantes apresentaram as notas maiores. The evaluations of the syrup stability were made visually and comparatively. When there was no significant change with the addition of the composition, the grade was zero. When there were improvements with addition of composition, the grade was 1. When the improvement was significant was given grade 2. Thus, the best fertilizer compositions had the highest grades.
[0044] Como procedimento, primeiramente adicionou-se as composições fertilizantes na água e, em seguida, foram adicionadas as caldas de pulverização. A agitação foi padronizada utilizando em uma mesa agitadora por 15 minutos. A avaliação visual foi realizada após os tempos de 30 minutos, 2 horas e 24 horas de repouso. As a procedure, the fertilizer compositions were first added to the water and then the spray grouts added. Stirring was standardized using on a shaker table for 15 minutes. Visual assessment was performed after 30 minutes, 2 hours and 24 hours of rest.
[0045] Para a avaliação da estabilidade da calda de pulverização para as duas diferentes composições fertilizantes foram utilizados os seguintes parâmetros: temperatura (5 °C, 25 °C), concentração da solução de glifosato de potássio 480 g/L na calda de aplicação (1,5 kg/hec, 4,0 kg/hec), presença de fertilizante a base manganês 4L/hec (sim, não), presença de fertilizante a base de zinco e molibdênio 0,02 L/hec (sim, não). The following parameters were used for the evaluation of spray solution stability for the two different fertilizer compositions: temperature (5 ° C, 25 ° C), concentration of potassium glyphosate solution 480 g / L in the application solution. (1.5 kg / hec, 4.0 kg / hec), presence of 4L / hec manganese fertilizer (yes, no), presence of 0.02 L / hec zinc and molybdenum fertilizer (yes, no ).
[0046] A Figura 1 apresenta um gráfico de desempenho das formulações testadas. Figure 1 presents a performance graph of the formulations tested.
[0047] Analisando a Figura 1, é possível verificar que a composição
fertilizante 1 mostrou-se mais robusta a mudanças de temperatura das caldas de pulverização. [0047] Looking at Figure 1, it can be seen that the composition Fertilizer 1 proved to be more robust to spray mix temperature changes.
[0048] A Figura 2 apresenta as fotos dos testes realizados para avaliação dos parâmetros na Figura 1. Pode-se verificar as avaliações visuais utilizadas para comparar as composições quando expostas a diferentes condições de temperatura, concentração de glifosato e presença de fertilizantes. As fotos foram tiradas com as caldas de concentrações pura, ou seja, sem composição fertilizante, e com as composições fertilizantes 1 e 2 acima descritas. Percebe-se claramente a menor quantidade de precipitado formado nas amostras utilizando a composição fertilizante 1. [0048] Figure 2 presents the photos of the tests performed to evaluate the parameters in Figure 1. It can be seen the visual evaluations used to compare the compositions when exposed to different temperature conditions, glyphosate concentration and presence of fertilizers. The photos were taken with the pure concentration syrups, ie without fertilizer composition, and with the fertilizer compositions 1 and 2 described above. It is clearly perceived the smallest amount of precipitate formed in the samples using the fertilizer composition 1.
[0049] A seguir foi realizado um teste utilizando a composição fertilizante 1. Esta composição fertilizante foi adicionada a uma mistura contendo 1,5 L/hec de solução de glifosato de potássio 480 g/L e l,5L/hec de solução de 2,4-D 806 g/L. A test was then performed using fertilizer composition 1. This fertilizer composition was added to a mixture containing 1.5 L / hec potassium glyphosate solution 480 g / L el, 5 L / hec solution 2, 4-D 806 g / l.
[0050] A composição fertilizante com propriedades adjuvantes foi adicionada nas seguintes concentrações: a) 0,1% em peso, b) 0,2% em peso, c) 0,3% em peso e d) 0,4 % em peso da calda de pulverização. Para a elaboração dos testes, foi considerado uma calda de aplicação de 100 L/hec. The fertilizer composition with adjuvant properties was added at the following concentrations: a) 0.1 wt%, b) 0.2 wt%, c) 0.3 wt% and d) 0.4 wt% of the spray solution. For the elaboration of the tests, it was considered an application syrup of 100 L / hec.
[0051] Como pode-se verificar pelos resultados apresentados naAs can be seen from the results presented in the
Figura 3, a adição da composição fertilizante com propriedades adjuvantes promove diminuição significativa de sólidos na calda de pulverização. Após a adição de 0,3 % da composição fertilizante 1 não é possível visualizar precipitados na calda. Figure 3, the addition of the fertilizer composition with adjuvant properties promotes significant decrease of spray solution solids. After the addition of 0.3% of the fertilizer composition 1 it is not possible to visualize precipitates in the syrup.
[0052] Para avaliar o efeito da composição fertilizante 1 com outros fertilizantes, foram utilizadas amostras comerciais do tipo líquidos solúveis a base de manganês, cobalto e molibdênio. Na Figura 4 tem-se a ilustração do desempenho das diferentes concentrações a), b), c) e d) da composição fertilizante 1. [0052] To evaluate the effect of fertilizer composition 1 with other fertilizers, commercial manganese, cobalt and molybdenum soluble liquid samples were used. Figure 4 shows the performance of the different concentrations a), b), c) and d) of the fertilizer composition 1.
[0053] Pode-se observar que a adição do produto melhorou
consideravelmente a estabilidade da calda de pulverização evitando assim a decantação de sólido e entupimentos de filtros e bicos. It can be seen that the addition of the product has improved considerably the stability of the spray solution thus avoiding solid settling and clogging of filters and nozzles.
[0054] Assim, conclui-se que a composição fertilizante com propriedade adjuvante da presente invenção, além de apresentar nutrientes necessários para o desenvolvimento das plantas, é capaz de melhorar a estabilização de misturas contendo herbicidas e fertilizantes em diferentes condições.
Thus, it is concluded that the adjuvant property fertilizer composition of the present invention, besides having nutrients necessary for plant development, is capable of improving the stabilization of mixtures containing herbicides and fertilizers under different conditions.
