Summary in the original language of the document
O Brasil é o maior produtor mundial e o Paraná o maior produtor nacional de soja orgânica. A cultura vem sendo uma alternativa na viabilização econômica de pequenas propriedades, sobretudo no Sudoeste Paranaense. Com a expansão da atividade aumenta a demanda por pesquisas visando obter alternativas aos agrotóxicos no manejo fitossanitário da cultura. Assim, no presente trabalho, o objetivo foi avaliar o efeito da aplicação de extratos vegetais sobre a produção de fitoalexinas, o desenvolvimento de doenças e a produtividade de soja. O trabalho foi realizado in vitro e in vivo na UTFPR Campus Dois Vizinhos. Avaliou-se o alho (Allium sativum - 10 mL.L-1), neem (Azadirachta indica - 5 mL.L-1) e timbó (Derris spp. - 6 mL.L-1), isoladamente ou em combinações. Os extratos vegetais a base de alho e neem induziram a produção de fitoalexinas gliceolinas em cotilédones e reduziram a incidência de oídio causado por Microsphaera diffusa em plantas de soja.
Summary translation
Brazil is considered the largest producer of organic soybean in the world and Paraná is the largest producer state. The crop has been an alternative to achieve economic feasibility in small farms, especially in the Southwest of Paraná. The demand for research about alternatives to pesticides has increased due to market and environment concerns. This study had the objective to evaluate the effect of plant extracts on the production of phytoalexins and make correlations with diseases and soybean yield. The work was carried out in vitro and in vivo at UTFPR Campus Dois Vizinhos. It was evaluated commercial formulations of garlic (Allium sativum - 10 mL.L-1), neem (Azadirachta indica - 5 mL.L-1) and timbó (Derris spp. - 6 mL.L-1). The plant extracts of garlic and neem induced the production of phytoalexins glyceolin in cotyledons of soybean and reduced the incidence of powdery mildew caused by Microsphaera diffusa.
