“…Possibly, this has to do with a phytotoxic effect of these products when used combined, which compromised seed germination. As stated by França-Neto et al (2016), the phytotoxic effect provokes atrophy of the root system, and also causes the epicotyl to get thicker, shorter, stiffer, and to present longitudinal fissures. These characteristics negatively affect the physiological quality of the seeds, as shown by the present study.…”

“…The treatment of soybean seeds in the industry showed physiological and sanitary advantages (Ludwig et al, 2011;Brzezinski et al, 2015;Conceição et al, 2016;Ferreira et al, 2016). However, problems were also reported, mainly in lots of low vigor seeds that had been submitted to excessively high volumes of slurry, resulted from the use of technological packs provided by the companies (Brzezinski et al, 2017).…”

-In soybean crops, industrial seed treatment is widely adopted, and it has allowed the development of new technologies, such as the use of dry powders. This work aimed to evaluate the effect of the industrial treatment, with and without the additional application of dry powder, on the physiological potential of soybean seeds. The experimental design was completely randomized, in a 4×2 factorial scheme, with four replications. Four chemical treatments were evaluated: 1) control, 2) carbendazim + thiram + thiamethoxam, 3) carbendazim + thiram, 4) thiamethoxam. Each trial was divided into one group that was treated and the other that remained untreated with the dry powder. The cultivars BRS 360 RR and BRS 284 were used and analyzed separately. The physiological potential of the seeds was determined by the following assessments: germination, first germination count, seedling emergence in sand, seedling total length, shoot length, and root length. Soybean cultivars respond differently to seed chemical treatments, regarding the effects on physiological potential. Using the dry powder results in problems in seed germination speed in the cultivar BRS 284. In the cultivar BRS 360 RR, the use of dry powder associated with thiamethoxam treatment reduces the physiological potential of the seeds.Index terms: Glycine max (L.) Merrill., fungicides, insecticides, germination, emergence of seedlings.Potencial fisiológico de sementes de soja tratadas industrialmente com e sem a aplicação de pó secante RESUMO -Na cultura da soja, o tratamento industrial de sementes é amplamente realizado e tem propiciado o desenvolvimento de novas tecnologias, como a utilização de pó secante. O objetivo deste trabalho foi avaliar o efeito do tratamento industrial de sementes, com e sem a aplicação de pó secante, sobre o potencial fisiológico de sementes de soja. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 4x2, com quatro repetições, sendo avaliados quatro tratamentos químicos de sementes: 1) testemunha, 2) carbendazim + thiram + tiametoxam, 3) carbendazim + thiram, 4) tiametoxam; todos na ausência e na presença de pó secante. As cultivares utilizadas foram a BRS 360 RR e a BRS 284, que foram analisadas separadamente. O potencial fisiológico das sementes foi determinado por meio das seguintes avaliações: germinação, primeira contagem de germinação, emergência de plântulas em areia, e comprimentos total, da parte aérea e da raiz das plântulas. As cultivares de soja respondem de forma diferenciada aos tratamentos químicos de sementes, quanto aos efeitos no potencial fisiológico. O pó secante resulta em problemas na velocidade de germinação das sementes da cultivar BRS 284. Na cultivar BRS 360 RR, o uso de pó secante associado ao tratamento com tiametoxam reduz o potencial fisiológico das sementes.Termos para indexação: Glycine max (L.)

“…In this context, it is necessary to use seed treatment, which is a technology that, when associated with plant genetic engineering and biotechnology, allows high soybean yield and producer satisfaction in meeting market demands (Ferreira et al, 2016). This process consists of applying compounds capable of protecting seeds against deleterious effects caused by pathogens, aiding to control storage fungi and protecting the seedlings in the initial establishment period of the crop, favoring sowing, emergence and development (Balardin et al, 2011).…”

Fungi are considered as the most important among pathogens due to the higher number of species and to the damage caused both in yield and in seed quality. Thus, aimed to verify the effect of fungicide and insecticide treatment on sanitary quality and physiological performance of soybean seeds before and after storage. Seeds from cultivars NS 7494, NS 8693 and NS 7338 IPRO were used, which were analyzed separately by a completely randomized design in a 3 x 6 factorial design, being three chemical treatment applications: 1) treated and evaluated; 2) treated, stored and evaluated; 3) stored, treated and evaluated; and six mixtures of fungicides and insecticides: (Imidacloprido + Tiocarbe) + (Carbendazim + Tiram), (Imidacloprido + Tiocarbe) + (Metalaxil-M + Fludioxonil), Thiamethoxam + (Carbendazim + Tiram), Thiamethoxam + (Metalaxil-M + Fludioxonil), (Fipronil + Piraclostrobina + Metil-tiofanato) and the control, which was added only water. The healthy test, germination, cold and accelerated aging tests were evaluated. Seed treatment products require at least two months to be effective in controlling Penicillium spp. and Fusarium spp. The mixtures containing Carbendazim + Tiram in its composition are efficient in the control of pathogens regardless of the application time of products.

RESUMOA performance fisiológica das sementes é afetada por diversos fatores dentre eles o armazenamento, a qualidade inicial do lote e do tratamento químico a que é submetido. Sendo assim, objetivou-se avaliar a qualidade fisiológica de semente de sojas tratadas submetidas ao armazenamento após tratamento industrial. O experimento foi conduzido na Fazenda Sperafico, no município de Sapezal no Mato Grosso. Foram utilizados dois lotes de cada variedade, com qualidades distintas, ou seja, um com alto vigor e outro com médio vigor. As sementes foram tratadas industrialmente, sendo utilizado para tratamento o fungicida Derosal Plus® na dosagem de 200ml de produto comercial para 100 kg de sementes e inseticida Standak® na dosagem de 200 ml de produto comercial para 100 kg de sementes. A avaliação da qualidade fisiológica foi realizada, no dia do tratamento das sementes e após 20, 40 e 60 dias de tratamento. As variáveis analisadas foram: teste de vigor em solo e ambiente controlado e emergência em solo e ambiente controlado. O delineamento experimental utilizado foi inteiramente casualisado, com tratamentos dispostos em fatorial, sendo dois níveis de vigor (alto e baixo) em quatro períodos de avaliação com três repetições por tratamento. Conclui-se que em ambas cultivares, ao se utilizar sementes com alto vigor as mesmas não sofrem decréscimos nos seus níveis de vigor e emergência tanto em ambiente controlado como em solo no período de armazenamento avaliado. Os níveis de vigor das sementes de baixo vigor tratadas, sofrem redução na qualidade fisiológica após 40 dias de armazenamento. PALAVRAS-CHAVE:Glycine max (L.) Merrill, germinação, tratamento.Plântula.
