“…The use of larger volumes of slurry in the treatment without causing consequences to the physiological quality of soybean seeds depends on several factors, such as the vigor. The determination of the ideal final volume, which does not affect the physiological quality of seeds, is extremely important, especially considering the effects that may occur throughout seeds storage (Segalin et al, 2013;Pereira et al, 2016;Brzezinski et al, 2017). Therefore, the objective in this study was to evaluate the effects of composition, components (separately or in combination), and volumes of slurry used in the industrial treatment of seeds of soybean cultivars on the physiological quality of the seeds during storage under controlled conditions.…”

Seeds treatment is a relevant factor in the soybean production system. The aim of this work was to evaluate composition and volumes of slurry used in industrial treatment of soybean seeds, and their physiological quality during storage. The experimental design was completely randomized, in a 20x4 factorial scheme, i.e. 20 seeds treatments and four storage periods (0, 30, 90 and 150 days). Seeds of the cultivars NS7667IPRO and NS7709IPRO were used. The slurry composition tested were a combination of fungicide and insecticide Standak top® (Fipronil + Piraclostrobin + Thiophanate Methyl), polymer L551Incotec® and water, in order to obtain the volumes of 450, 700 and 1200 mL.100 kg of seeds-1, and the controls treatment. The physiological quality was assessed by germination in sand and accelerated aging tests. Genotypes showed distinct tolerance to seed treatment industrial , slurry volumes and storage. Treatments with Standak top®, polymer and water, with volumes of up to 1200 mL.100 kg seed-1, and stored for 150 days in cold chamber were not harmful for germination of cultivar NS7667IPRO. As for cultivar NS7709IPRO, the tolerance was 90 days. Treating seeds with large slurry volumes is detrimental to maintain seeds vigor during storage, with depreciation after 30 days, especially with water predominance.

“…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). To solve this problem, companies have used dry powder in order to induce seeds to dry fast and evenly.…”

-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.)

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.)

“…It is important to point out that, besides the storage conditions and the active ingredients, the different performance of soybean seeds above-mentioned regarding slurry volume may be related to the initial level of vigor and germination of the lot prior IST, so that seeds of higher initial physiological quality are potentially more tolerated to the prejudicial effects that a fast imbibition process may have on seed membranes (Brzezinski et al, 2017).…”

Industrial seed treatment assures uniform coverage of seeds with insecticides, fungicides, micronutrients and bioestimulant at precise dose, however often resulting in higher slurry volume. Furthermore, seeds are coated long periods of time prior sowing and may influence germination and vigor. Thus, the aim of this work was to evaluate the influence of seven industrial seed treatments and their respective slurry volumes on the physiological potential of soybean seeds at 0, 15, 30, 45, 60 and 90 days of storage. In each storage period, the variables germination, accelerated aging test and emergency speed index were evaluated and studied in the repeated measures in time model. The products used were: fungicide (thiabendazole, fludioxonil and mefenoxam), insecticide (thiametoxam), insecticide/nematicide (abamectin), micronutrients (cobalt and molybdenum), bioregulator, drying powder and polymer. High volumes of seed-coating mixtures reduce the physiological quality of soybean seeds over storage. However, the slurry composition also influenced on the maintenance of the seed germination and vigor throughout the storage.
