The fungus are the main microorganisms present in seeds, is the main cause of deterioration and loss in production. The anthracnose caused by C. truncatum associated with soybean seeds as has main vehicle for introduction into the planting areas can be detected in all stages of crop development, from the cotyledons to the end of the cycle, being present in the stems, veins, leaflets and pods. Thus aimed to evaluate the influence of using different products fungicides as seed treatment, where the seeds were inoculated with the pathogenic fungus and treated with the chemicals They take Carbedazim + Fludioxonil + metalaxyl-M and carboxin + thiram. For each fungicide product was two tramentos done using the doses recommended by the manufacturer and 75% of dose. We evaluated health, germination and promote plant (Plant growth, fresh weight and dry weight of root and shoot). This work concludes that the use of fungicide controls significantly seeds infected with C. truncatum and presents a significant improvement as the development of structures seedling.

Seed treatment with growth regulators, especially salicylic acid, is a promising alternative to the seed industry because it is an important inducer of resistance to diseases and pests, as well as acting significantly on quality and seed yield. The objective of this study was to evaluate the performance of rice seed treated with different concentrations of salicylic acid, as well as assess the crop yield and seed quality. The treatments consisted of increasing levels of 0, 50, 100, 150 and 200 mg.L-1 salicylic acid. To this was prepared a stock solution of salicylic acid and the highest concentration by successive dilution in distilled water, the other concentrations were obtained. The physiological quality of seeds produced was treated and evaluated by tests of vigor and germination, and after harvest were evaluated seed yield. It follows that treatment of rice seeds with salicylic acid concentrations up to 130 mg.L-1 at a dose of 2 mL.kg-1 seed does not affect the germination and affects the strength, however provides substantial increases in the yield of seeds. The seed treatment with salicylic acid has no influence on seed quality produced.

Sorting Process

The occurrence of green seeded soybeans [Glycine max (L.) Merrill] is a problem closely related to unfavorable climatic conditions, mainly drought, that occurs during the final stages of seed maturation. This problem causes serious losses to soybean seed quality in Brazil. In these seeds, chlorophyll is not properly degraded during maturation, drastically reducing seed quality. Using the chlorophyll fluorescence technique, it is possible to remove green seeds from the seed lot, improving seed quality in several species in which the occurrence of green seeds is also a problem. The objective of this research was to study the use of the chlorophyll fluorescence technique in sorting green seeds from soybean seed samples and its effects on quality. Five seed samples of soybean, cultivar TMG 113 RR, with 0%, 5%, 10%, 15%, and 20% of green seeds were used in this study. Seeds from each sample were sorted into two fractions based on the chlorophyll fluorescence signals and then compared to the control (non-sorted seeds). The sorting process showed great differences between the low and high chlorophyll fluorescence fractions. It was concluded that: green seeds of soybeans present high chlorophyll fluorescence and that this characteristic affects the quality of the seeds; it is possible to improve the quality of soybean seed by removing green seeds using the chlorophyll fluorescence sorting technique.

Abstract: 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 soja é uma das culturas mais cultivadas do planeta, sendo o Brasil, um de seus maiores produtores. É uma fonte barata e rica de óleo vegetal. O tratamento de sementes é amplamente utilizado para evitar perdas por patógenos e insetos na fase inicial do estabelecimento das plantas. Sendo uma das formas de se evitar a perda da qualidade. O objetivo deste trabalho foi avaliar o efeito do tratamento químico com inseticida/fungicida e polímero na qualidade final das sementes de soja. Foram utilizadas sementes do cultivar M-7110 Ipro, produzida na safra 2016/17 na região de Rio Verde, GO, com grau de umidade de 12%. Os tratamentos de sementes utilizados foram: Testemunha, Caixa vigor e praga (200 mL de Cruiser+ 100 mL de fipronil + 100 mL de Maxim XL); 100 mL + 100 mL de Standak + Maxim XL (Fipronil 250 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L) e 300 mL + 100 mL de Cropstar + Maxim XL (Imidacloprido 150 g/L e Tiodicarbe 450 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L). Foram utilizados o teste de germinação, emergência e a taxa de crescimento de plântulas. O tratamento Cropstar + Maxim XL se destacou como o melhor para o tratamento das sementes de soja quando comparado aos outros tratamentos utilizados neste trabalho. O uso de Standak + Maxim ML foi inferior aos demais para o tratamento de sementes de soja.Palavras-Chave: tratamento de sementes; Glycine max; vigor.ABSTRACTSoy is one of the most cultivated crops on the planet, being Brazil, one of its largest producers. It is a cheap, rich vegetable oil fountain. Seed treatment is widely used to avoid losses by pathogens and insects in the early stages of plant establishment. Being one of the ways to avoid the loss of quality. The purpose of this work was to evaluate the effect of chemical treatment with insecticide/fungicide and polymer in the final quality of soybean seeds. Seeds of cultivar M-7110 Ipro, produced in the harvest 2016/17 in the region of Rio Verde, GO, with a moisture content of 12% were used. The seeds treatments used were: Control, Caixa vigor e praga (200 mL de Cruiser+ 100 mL de fipronil + 100 mL de Maxim XL); 100 mL + 100 mL de Standak + Maxim XL (Fipronil 250 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L) e 300 mL + 100 mL de Cropstar + Maxim XL (Imidacloprido 150 g/L e Tiodicarbe 450 g/L + Metalaxil-M 10 g/L e Fludioxonil 25 g/L). The germination test, emergency and the growth rate of seedlings were tested. The treatment Cropstar + Maxim XL stood out as the best for treating soybean seeds when compared to other treatments used in this work. The use of Standak + Maxim ml was inferior to the other for the treatment of soybean seeds.Keywords: seed treatment; Glycine max; vigour

Seed treatment with beneficial microbes or biocontrol agents is called biological seed treatment. Vegetable seed quality includes the physical, pathological, genetic and physiological that leads to successful crop establishment and yield . Use of BCA’s as seed treatments can play an important role in most aspects of seed quality, and be of particular benefit for improved seeding growth under stressful conditions. It not only improve the quality of seed but also protect seed from different seed borne diseases and make the seed healthy.
