“…There were no significant differences in the TGM in the presence or absence of chemical and biological treatment of soybean seeds. These results corroborate those of Goulart, Roese and Melo (2015), in which, in 2 years, ST with and without fluquinconazole did not affect the TGM regardless of whether fungicide was applied to soybean stems. However, in the present study, there were significant differences in the TGM between the municipalities, and the TGM was 6.1% and 8.4% higher in Tupanciretã than in Cândido Godói and Barra Funda, respectively (Table 5).…”

“…(Table 4). This result is related to the lower incidence of foliar diseases and the lower percentage of defoliation of soybean plants when ST is performed (GOULART;ROESE;MELO, 2015) by increasing the production of photoassimilates and, consequently, grain filling.…”

“…+ Biozyme ® was 2.8% and 1.8% lower than treatment with fludioxonil and fludioxonil + Trichoderma spp., respectively. In addition to the lower defoliation and lower incidence of diseases (GOULART; ROESE; MELO, 2015), the combination of a fungicide, Trichoderma spp., and Biozyme ® may have supplied the required micronutrients for plant development, which favored grain filling (AVELAR et al, 2011).…”

In the search for homogeneous planting density and satisfactory results in soybean development and yield, the treatment of seeds can be carried out using a combination of chemical fungicides, growth stimulators, and other biological agents. The objective of this study is to evaluate the effect of chemical and biological inputs for soybean seed treatment on crop development and yield. Experiments were carried out in the 2010/2011 growing season in three municipalities of Rio Grande do Sul using the following treatments: fungicide fludioxonil, Trichoderma spp., fludioxonil + Trichoderma spp., fludioxonil + Trichoderma spp. + the growth stimulator Biozyme ® , and a control (untreated). The total number of pods in treatment with Trichoderma spp. and the other treatments were up to 77% higher than that of the control. The grain yield of treatments with fludioxonil, fludioxonil + Trichoderma spp., and fludioxonil + Trichoderma spp. + Biozyme ® was up to 14% higher than that of the control. These results indicate that fludioxonil combined with the fungus Trichoderma spp. and Biozyme ® is indicated for treating soybean seeds and increases crop development and grain yield.RESUMO -Na busca por estande de plantas homogêneo e resultados satisfatórios no desenvolvimento e produção de soja, pode ser realizado o tratamento de sementes combinando fungicidas químicos, bioestimuladores e outros produtos biológicos. Dessa forma, objetivou-se avaliar a interferência de insumos químico e biológico em tratamento de sementes no desenvolvimento e produção de soja. Para isso, foram conduzidos experimentos no ano agrícola 2010/2011 em três localidades do Rio Grande do Sul, utilizando-se os seguintes tratamentos de sementes: fungicida fludioxonil; Trichoderma spp.; fludioxonil + Trichoderma spp.; fludioxonil + Trichoderma spp. + Biozyme ® ; e testemunha (sem tratamento). Para o número total de vagens, o tratamento com Trichoderma spp. e os demais tratamentos conjugados apresentaram até 77% mais vagens do que a testemunha. Os tratamentos fungicida fludioxonil, fungicida fludioxonil + Trichoderma spp. e fungicida fludioxonil + Trichoderma spp. + Biozyme ® apresentaram até 14% maior produtividade do que a testemunha. O fungicida fludioxonil foi indicado para tratamento de sementes de soja conjugado com o fungo Trichoderma spp. e o bioestimulador Biozyme ® , por promoverem o desenvolvimento de plantas e o aumento da produtividade de soja.

“…The Carbendazim + Tiram fungicide contains in its composition the active carbendazim, from the benzimidazole group, and Tiram, from the dimethyldithiocarbamate group. According to Goulart et al (2015), the fungicides from the benzimidazole group act to inhibit the DNA synthesis of fungi, whereas those from the dimethyldithiocarbamate group act to inactivate the essential enzymes. Therefore, this fungicide is extremely efficient in fungi control and seed protection.…”

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.

A semente é considerada o principal insumo agrícola, sendo fundamental para o sucesso da produção. Para que uma semente seja considerada de excelência, deve apresentar qualidade física, fisiológica, genética e sanitária. Sendo esses fatores determinantes para que ela consiga expressar todo o seu potencial. O ataque de agentes fitopatogênicos afeta o sucesso da produção agrícola, uma vez que pode limitar o crescimento e o desenvolvimento das culturas. Além do fato das sementes serem consideradas eficientes fontes de disseminação de patógenos, dentre os principais destacam-se os fungos, bactérias, vírus e alguns nematoides. Assim, a adoção de métodos de controle é fundamental para evitar que patógenos sejam transmitidos por sementes, como o controle químico, físico, biológico e alternativo como o uso de extratos e óleos vegetais. A adoção e a eficiência destas técnicas de controle de patógenos encontrados nas sementes, passa pelo tratamento preventivo e sua eficácia no combate aos dos organismos presentes interna e externamente aderido as sementes, possibilitando a manutenção de sua qualidade.
