The harmful effects caused by the use of toxic substances in agriculture have led to the development of alternative solutions, and researchers have focused on understanding the effectiveness and potential of plant extracts in agriculture. The aim of this systematic review was to understand the situation of research and scientific dissemination, as well as how current science has approached the use of plant extracts in agriculture, especially in seed applications. There is potential on the use of plant extracts in agriculture, demonstrated by a high number of publications over the last ten years, especially in the years 2018, 2019 and 2020, and Brazil stands out as the main country on this research area. Control of phytopathogenic microorganisms, insect control, biostimulant effect, resistance induction and herbicide effect have been the main themes explored for use in agriculture. The direct application of plant extracts is centered on plants and seeds, being this latter mainly focused on the control of phytopathogenic organisms and biostimulating effect.

Plant extracts effects have been regarded and proven in researches under different applications in agriculture, including seed treatment. The plant extracts effectiveness is attributed to the presence of certain classes of compounds; therefore, studies that aim to identify and quantify these composites, which are present in plant extracts used in agriculture, are important, as well as the seed treatment. This research aimed to understand and describe through a systematic review, what were the main carried approaches, classes and identified compounds in studies with plant extracts to different applications in agriculture and the seed treatment. The period 2015 to 2020 was the one that exposed the higher research publication indexes, considering the theme under analysis, plant extracts in agriculture, seeking to identify or quantify the presence of metabolic composites, indicating a growing interest in this theme. Such studies pursued identifying and/or quantifying the compounds that are present in the plant extracts. The phenolic compounds constitute the priority class of metabolites to different functions, effects and applications in agriculture, mainly in seed treatment. The terpenes present a substantial potential as bioinsecticides to agriculture. Plant species that are rich in phenolic and terpenes compounds are a significant source of alternative control in the protection of the productive system.

RESUMO o presente artigo tem por objetivo apresentar as origens e as proposições fundamentais da Doutrina Social da Igreja Católica (doravante DSI) e seus possíveis pontos de contato e de diálogo com a economia social de mercado (doravante ESM), de origem alemã, e com o novo desenvolvimentismo (doravante ND), originado a partir do Consenso de São Paulo. Não se trata obviamente de afirmar que a ESM e o ND são desdobramentos diretos da DSI; ou que esta seja plenamente compatível com as duas primeiras. Nosso objetivo neste artigo é mostrar os pontos nos quais a ESM e o ND tem em comum com a DSI; de maneira a ampliar o escopo de apoio político ao novo desenvolvimentismo na sociedade brasileira, argumentando que um desenvolvimentismo em sentido amplo - que inclui tanto a ESM como o ND - não são incompatíveis com a DSI e, dessa forma, com a visão Cristã sobre o Mundo, o Homem e os Sistemas Econômicos. Do ponto de vista da Doutrina Social da Igreja, as proximidades entre ESM e ND são suficientes para afirmar que é perfeitamente razoável ver a abordagem ND da economia como um bem possível que oferece respostas críveis e bastante precisas aos problemas e preocupações apresentados pelos pontífices da Igreja Católica. Dado que a DSI é base inspiradora de muitos movimentos políticos relevantes, como a democracia cristã, é extremamente relevante analisar as possibilidades políticas do novo desenvolvimentismo nos mais variados campos do espectro político.
