Mais especificamente a presente invenção é capaz de fornecer uma composição com propriedades bioestimulantes e bioprotetoras para o controle de fungos em plantas em geral, como fungos em geral, como por exemplo, da ordem Pucciniales, como Puccinia spp., Phakopsora euvitis, Puccinia polysora, Puccinia graminis f. sp. tritici, Phakopsora pachyrhizi, Hemileia vastatrix, Uromyces spp. que são os agentes causais de ferrugem em várias espécies vegetais, em sistema de cultivo orgânico e convencional. “COMPOSITION FOR CONTROL OF FUNGAL DISEASES IN PLANTS AND METHOD OF PRODUCING THE SAME” FIELD OF THE INVENTION [001] The present invention refers to a composition containing extracts of algae and microalgae and/or plants and metallic elements for applications in agriculture, for improve protective effect against pathogens concomitantly with a reduction in their incidence. More specifically, the present invention is capable of providing a composition with biostimulant and bioprotective properties for the control of fungi in plants in general, such as fungi in general, for example, from the order Pucciniales, such as Puccinia spp., Phakopsora euvitis, Puccinia polysora, Puccinia graminis f. sp. tritici, Phakopsora pachyrhizi, Hemileia uvatrix, Uromyces spp. which are the causal agents of rust in several plant species, in organic and conventional cultivation systems.
ESTADO DA TÉCNICA STATE OF THE TECHNIQUE
[002] Existe uma necessidade substancial de reduzir os teores de substâncias tóxicas nos alimentos na maior extensão possível, e reprimir, na medida do possível, quaisquer substâncias tóxicas, através do uso de aditivos agrícolas. [002] There is a substantial need to reduce the levels of toxic substances in food to the greatest extent possible, and to suppress, as far as possible, any toxic substances, through the use of agricultural additives.
[003] Além disso, existe também uma crescente demanda por alimentos e o uso sustentável de recursos ambientais que figura como um grande desafio para a agricultura moderna, que tem como principal objetivo o incremento de produtividade. Por exemplo, algumas medidas em alguns países, como a Diretiva 2009/128/EC visa estimular o desenvolvimento de abordagens ou técnicas alternativas para reduzir a dependência do uso de pesticidas e a necessidade do desenvolvimento de novos produtos naturais adequados para o controle de pragas agrícolas, como uma alternativa aos pesticidas sintéticos que desempenharam um papel importante durante as últimas décadas. [003] Furthermore, there is also a growing demand for food and the sustainable use of environmental resources, which represents a major challenge for modern agriculture, whose main objective is to increase productivity. For example, some measures in some countries, such as Directive 2009/128/EC aim to stimulate the development of alternative approaches or techniques to reduce dependence on the use of pesticides and the need for the development of new natural products suitable for controlling agricultural pests. , as an alternative to synthetic pesticides that have played an important role during recent decades.
[004] Nesse cenário, os sistemas de cultivo orgânicos ou agricultura orgânica são conhecidos por serem sistemas de produção que evitam ou eliminam em grande parte o uso de fertilizantes e defensivos sintéticos,
reguladores de crescimento e aditivos de produção, culturas e ração animal. Assim, em alternativa ao uso de fertilizantes sintéticos, os sistemas de agricultura orgânica contam com rotação de culturas, resíduos de culturas, esterco animal, leguminosas, adubos verdes e resíduos orgânicos não agrícolas, bem como o uso de rochas e minerais e aspectos de controle biológico de pragas e patógenos. Isso permite manter a produtividade e a estrutura do solo, fornecer nutrientes às plantas e controlar insetos, plantas daninhas e outras pragas. [004] In this scenario, organic farming systems or organic agriculture are known to be production systems that largely avoid or eliminate the use of synthetic fertilizers and pesticides, growth regulators and additives for production, crops and animal feed. Thus, as an alternative to the use of synthetic fertilizers, organic farming systems rely on crop rotation, crop residues, animal manure, legumes, green manures and non-agricultural organic waste, as well as the use of rocks and minerals and control aspects biological pests and pathogens. This allows you to maintain productivity and soil structure, provide nutrients to plants and control insects, weeds and other pests.
[005] Essa atividade tem crescido muito ao redor do mundo, principalmente pela questão de preservação do meio ambiente e também pela necessidade de toda a sociedade por alimentos mais saudáveis, que não sejam prejudiciais à saúde. [005] This activity has grown a lot around the world, mainly due to the issue of preserving the environment and also due to the need of society as a whole for healthier foods that are not harmful to health.
[006] O sistema de cultivo orgânico requer o cumprimento de algumas diretrizes como escolha do tipo de adubação, prevenção e controle de pragas e doenças e verificação dos insumos admitidos para uso na propriedade orgânica. [006] The organic cultivation system requires compliance with some guidelines such as choosing the type of fertilizer, preventing and controlling pests and diseases and checking the inputs admitted for use on the organic property.
[007] Os maiores mercados para produtos orgânicos estão na Europa, Estados Unidos e Japão. Estima-se que o mercado de produtos orgânicos cresça e se expanda ainda mais, mesmo em países desenvolvidos. Na Europa, o setor de produtos orgânicos tem uma taxa de crescimento de 10% ao ano e nos Estados Unidos, o crescimento anual concentra-se entre 15 e 20%. Contudo, o mercado orgânico na América Latina ainda é considerado escasso e há uma variação acentuada nos dados disponíveis. [007] The largest markets for organic products are in Europe, the United States and Japan. The market for organic products is estimated to grow and expand even further, even in developed countries. In Europe, the organic products sector has a growth rate of 10% per year and in the United States, annual growth is concentrated between 15 and 20%. However, the organic market in Latin America is still considered scarce and there is a marked variation in available data.
[008] De acordo com pesquisas na área de agricultura orgânica, ainda faltam tecnologias de como produzir em diferentes climas e condições de solo, ou seja, falta desenvolvimento de processos e produtos adequados para responder a diferentes condições climáticas, diferentes sistemas agrícolas. [008] According to research in the area of organic agriculture, there is still a lack of technologies on how to produce in different climates and soil conditions, that is, there is a lack of development of suitable processes and products to respond to different climatic conditions, different agricultural systems.
[009] Diversas soluções foram desenvolvidas para tornar mais eficiente os sistemas de cultivo orgânico. [009] Several solutions have been developed to make organic farming systems more efficient.
[010] O documento W02020016825 reivindica um método para melhorar a eficiência do uso da água e/ou produtividade da água nas plantas e/ou o manejo da água na agricultura, que compreende as etapas: (i) ter plantas
para serem tratadas ou com necessidade do mesmo, e (ii) nutrir as plantas através do solo, com uma quantidade eficaz de uma composição que compreende ao menos um extrato de algas e microalgas e/ou ao menos um extrato de planta. No entanto, esse método apresenta limitações como a necessidade de as plantas estarem em uma condição de não seca, como uma condição não estressante. Nesse sentido, referido método não pode ser aplicado a plantas afetadas por patógenos como fungos. [010] Document W02020016825 claims a method for improving water use efficiency and/or water productivity in plants and/or water management in agriculture, which comprises the steps: (i) having plants to be treated or in need thereof, and (ii) nourish the plants through the soil, with an effective amount of a composition comprising at least one algae and microalgae extract and/or at least one plant extract. However, this method has limitations such as the need for plants to be in a non-dry condition, such as a non-stressful condition. In this sense, this method cannot be applied to plants affected by pathogens such as fungi.
[011 ] O WO2018075948 divulga um método de modulação do crescimento da planta que compreende administrar a uma planta uma quantidade de uma composição contendo Kappaphycus que é eficaz para modular pelo menos um aspecto do crescimento na planta, pelo menos uma característica de saúde na planta, ou ambos. Essa revelação também apresenta deficiências, pois não é capaz de propor uma condição que irá combater ou sanar as questões de infestação por fungos. [011] WO2018075948 discloses a method of modulating plant growth which comprises administering to a plant an amount of a composition containing Kappaphycus that is effective for modulating at least one aspect of growth in the plant, at least one health characteristic in the plant, or both. This disclosure also has deficiencies, as it is not able to propose a condition that will combat or remedy fungal infestation issues.
[012] Os fungos da ordem Pucciniales como Puccinia, Phakopsora euvitis, Puccinia polysora, Puccinia graminis f. sp. tritici, Phakopsora pachyrhizi, Hemileia vastatrix, Uromyces spp. estão presentes em todas as partes verdes da planta com predileção por condições úmidas, sendo que dentro de dois a três dias após a infecção pelo fungo, manchas amareladas aparecem nos tecidos das folhas. À medida que a doença se desenvolve, as manchas tornam-se proeminentes, aumentam gradualmente de tamanho e alongam-se na direção das nervuras das folhas, formando pústulas que rompem a epiderme, expondo os esporos fúngicos que são levemente amarelados, mas no geral são marrom- acinzentados. Essa infecção é conhecida como ferrugem, que, se não for adequadamente tratada, aumentará gradualmente e se transformará em "pústulas" grandes e de aparência irregular. Depois de um tempo, as pústulas se abrem e liberam esporos que são dispersos pelo vento ou respingos de água pelo ambiente circundante, infectando outras plantas. Uma das maneiras de tratar essa doença fúngica é por meio do controle químico com triazóis e estrobilurinas.
[013] Como pode ser verificado a partir dos dados do estado da técnica, resta claro, portanto, a necessidade no estado da técnica de produto que possa ser utilizado em sistemas de cultivo orgânico para combater e evitar doenças causadas por fungos e que possam ser aplicados a plantas em uma condição estressante. [012] Fungi from the order Pucciniales such as Puccinia, Phakopsora euvitis, Puccinia polysora, Puccinia graminis f. sp. tritici, Phakopsora pachyrhizi, Hemileia uvatrix, Uromyces spp. are present in all green parts of the plant with a predilection for humid conditions, and within two to three days after infection by the fungus, yellowish spots appear on the leaf tissues. As the disease develops, the spots become prominent, gradually increase in size and stretch towards the veins of the leaves, forming pustules that break the epidermis, exposing the fungal spores that are slightly yellowish, but in general are grayish-brown. This infection is known as rust, which, if not properly treated, will gradually enlarge and turn into large, irregular-looking "pustules." After a while, the pustules open and release spores that are dispersed by wind or splashing water throughout the surrounding environment, infecting other plants. One of the ways to treat this fungal disease is through chemical control with triazoles and strobilurins. [013] As can be seen from the prior art data, it is therefore clear that there is a need in the prior art for a product that can be used in organic cultivation systems to combat and prevent diseases caused by fungi and that can be applied to plants in a stressful condition.
[014] A tecnologia apresentada neste documento contribui na preservação dos recursos naturais, mas também na qualidade da saúde humana, que contempla os consumidores e os próprios trabalhadores rurais, ao fornecer uma formulação de produtos com a capacidade de atuar contra o patógeno e aumentar a resistência das plantas sem agredir o meio ambiente, como o composto bioestimulante e bioprotetor. [014] The technology presented in this document contributes to the preservation of natural resources, but also to the quality of human health, which includes consumers and rural workers themselves, by providing a product formulation with the ability to act against the pathogen and increase the plant resistance without harming the environment, such as the biostimulant and bioprotective compound.
[015] Nesse sentido, a matéria aqui reivindicada soluciona os problemas do estado da técnica, à medida que provê uma composição com ação direta contra o patógeno, diminuindo a ação do mesmo e ativando o sistema de defesa natural das plantas e para promover uma melhor performance produtiva das culturas, por maximizar a assimilação de CO2, mediante ativação da Rubisco, ativando hormônios de crescimento como AIA e ácido giberélico e também aumentando a divisão celular. [015] In this sense, the material claimed here solves the problems of the prior art, as it provides a composition with direct action against the pathogen, reducing its action and activating the plants' natural defense system and to promote better productive performance of crops, by maximizing the assimilation of CO2, through the activation of Rubisco, activating growth hormones such as AIA and gibberellic acid and also increasing cell division.
[016] Com o aumento da produtividade, a produção rural terá um maior retomo financeiro, o que auxiliará na sua manutenção e aumento da atividade. [016] With the increase in productivity, rural production will have a greater financial return, which will help in its maintenance and increased activity.

[060] Conforme já informado anteriormente as Figuras 4A-E mostram fotos de ensaios in vitro de germinação de uredósporos de Hemileia vastatrix inoculados contendo diferentes concentrações da composição da presente invenção. [060] As previously reported, Figures 4A-E show photos of in vitro germination tests of Hemileia uvatrix uredospores inoculated containing different concentrations of the composition of the present invention.
[061 ] Esses ensaios foram realizados a partir de 50 pL da suspensão de uredósporos (105/pL) inoculados em placas de Petri contendo 1 ,5% de ágar e água com 4 diferentes concentrações da composição da presente invenção (Figura 4A - amostra de controle sem a composição; Figura 4B - concentração de 1 m L do produto diluído em 9ml_ de água; Figura 4C - concentração de 2,5 m L do produto diluído em 7,5 ml_ de água; Figura 4D - concentração de 5,0 ml_ do produto diluído em 5ml_ de água; Figura 4E - concentração de 7,5 m L do produto diluído em 2,5 ml_ de água e Figura 4F - concentração de 10,0 ml_ do produto, não diluído. As placas de amostra de controle continham apenas ágar água. [061] These tests were carried out using 50 pL of the uredospore suspension (105/pL) inoculated in Petri dishes containing 1.5% agar and water with 4 different concentrations of the composition of the present invention (Figure 4A - sample of control without the composition; Figure 4B - concentration of 1 m L of the product diluted in 9 ml of water; Figure 4C - concentration of 2.5 m L of the product diluted in 7.5 ml of water; Figure 4D - concentration of 5.0 ml_ of the product diluted in 5ml_ of water; Figure 4E - concentration of 7.5 m L of the product diluted in 2.5 ml_ of water and Figure 4F - concentration of 10.0 ml_ of the product, undiluted. The sample plates of control contained only water agar.
[062] As placas foram incubadas a 23°C no escuro por 24h e 100 esporos/placa foram avaliados em microscópio de luz. [062] The plates were incubated at 23°C in the dark for 24h and 100 spores/plate were evaluated under a light microscope.
[063] Assim, foram considerados germinados os esporos com tubo germinativo maior do que o tamanho do esporo. A porcentagem média de germinação para cada concentração do composto foi calculada usando a fórmula [1 - (% GF / % GC)] x 100, em que “%GF” é a porcentagem média de germinação de esporos em ágar suplementado com o composto e “%GC” a porcentagem média de esporos em ágar sem o composto (controle). [063] Thus, spores with a germ tube larger than the size of the spore were considered germinated. The average germination percentage for each compound concentration was calculated using the formula [1 - (% GF / % GC)] x 100, where “%GF” is the average percentage spore germination on agar supplemented with the compound and “%GC” the average percentage of spores in agar without the compound (control).
[064] A Tabela 1 abaixo mostra os resultados de referido teste de germinação para cada amostra e suas concentrações.
