| English abstract | This study aimed to evaluate the health and physiological quality of soybean seeds due to the chemical treatment of seed and leaf in the field. The experiments were performed in the Laboratories of Plant Pathology and Seeds of the University of Passo Fundo – UPF of College of Agronomy and Veterinary Medicine – FAMV. The cultivars used in this work were FUNDACEP 53 RR and FUNDACEP 55 RR from the research field of the UPF, harvest was in 2009-2010. The work was composed of 28 treatments for each cultivar, 56 in total. The samples of both cultivars were subjected to different combinations of seed treatment, Cropstar® + Derosal plus®, Cropstar® + Derosal plus® + Atento®, Standak Top® and control (no fungicide aplication), and the doses being used in accordance with the recommendations of the commercial products. The fungicides applications in the aereal part were made with Opera® (Piraclostrobina+Epoxiconazol), Sphere Max® (Trifloxistrobina+Ciproconazol) in doses of 150, 500 mL ha-1 and control (no fungicide aplication). The experiment design was randomized in all the experiments. The germination and seed health were also evaluated. The pathogens of the genero Aspergillus sp., Penicillium sp. and Alternaria alternata, were the predominant fungi with the highest rates for Penicillium spp. and Aspergillus spp. On the other hand, the physiological seed quality was preserved, with no significant effect of phytotoxicity observed |

Os experimentos foram realizados nos Laboratórios de Fitopatologia e de Sementes da Universidade de Passo Fundo – UPF da Faculdade de Agronomia e Medicina Veterinária – FAMV. As cultivares utilizadas para o trabalho foram FUNDACEP 53 RR e FUNDACEP 55 RR, provenientes do campo experimental da UPF, safra 2009-2010. O trabalho foi composto de 28 tratamentos para cada cultivar, totalizando 56. As amostras das duas cultivares foram submetidos a diferentes combinações de tratamento de sementes, Cropstar®+Derosal plus®, Cropstar®+ Derosal plus®+Atento®, Standak Top® e testemunha (sem aplicação de fungicidas), sendo as doses utilizadas de acordo com as recomendações dos produtos comerciais. As aplicações de fungicidas na parte aérea foram com Opera® (Piraclostrobina+Epoxiconazol), Sphere Max® (Trifloxistrobina+Ciproconazol) nas doses de 150, 500 mL ha-1 e testemunha (sem aplicação de fungicidas). O delineamento experimental foi inteiramente casualizado em todos os experimentos. Foram realizadas avaliações de germinação e sanidade das sementes. Os patógenos que predominaram foram fungos dos gêneros Aspergillus spp. , Penicillium spp. e Alternaria alternata, com os maiores índices para Penicillium spp. e Aspergillus spp. Por outro lado, a qualidade fisiológica das sementes foi preservada, não se observando efeito de fitotoxicidade |
