“…Zuffo et al (2017b), when evaluating the effect of harvest times for the soybean BRS 820 RR ® cultivar, in Lavras, Minas Gerais state, Brazil, also demonstrated the incidence of these pathogens. These are pathogens which occur widely and have a great importance in Brazil, causing significant losses in the production and reduction in the quality of soybean seeds (Danelli et al 2011).…”

Nitrogen fertilization may interfere in the quality of soybean seeds. This study aimed to determine the physiological and sanitary quality of soybean seeds, in response to levels and times of nitrogen (N) application associated with Bradyrhizobium japonicum inoculation. Treatments were arranged in a randomized block design, in a 2 × 3 × 4 factorial arrangement [two soybean cultivars (BRS 1074 IPRO and ST 797 IPRO), three application times (sowing, 30 and 50 days after emergence) and four N levels (0 kg ha-1, 20 kg ha-1, 40 kg ha-1 and 60 kg ha-1), with four replicates. The 1,000-seed mass, moisture content, germination rate, seedling height, shoot length, primary root length, total seedling dry matter, electrical conductivity, mechanical damage, vigor and viability (tetrazolium test) and sanitary quality of the seeds were measured. The use of mineral N, associated with the inoculation of B. japonicum bacteria, does not prove to be consistent, in terms of its effects on the physiological quality of soybean seeds, although the incidence of pathogens may be reduced.

“…The microorganisms associated with seed years have been neglected their applications and effects on plant stimulation (MORAIS et al, 2016). On the other hand, these plant pathogen associated organisms associated with imbalance associations in the seed-borne population amplify epidemics, serving as initial inoculum and introduction at long distances in the production fields (DANELLI et al, 2011).…”

One of the elements capable of explaining the epidemics of diseases in the fields of corn production is the amount of initial inoculum present in seeds. The objective of this paper was to study the health and physiological quality of maize hybrids grown in the 2019 crop. The experiment was carried out using 22 hybrids represented by: 13K21PW Morgan©, 14K185PW Morgan©, 230 PRO 3 DKB©, 290 PRO 3 DKB© , 3040 VIP3 LG©, 3055 VIP3 LG©, 30F35 Pioneer ©, 310 PRO 3 DKB©, 345 PRO 3 DKB©, 8882 Coded DKB, CBS15C385PW Morgan©, CBS15D089PW Morgan©, CBS15SE137PW Morgan©, Coded x40K205 (3898) Pioneer, K9606 VIP3 KWS©, MG580PW Morgan©, MG652PW Morgan©, SH 7930 PRO 2 Sta Helena©, SH 7990 PRO 2 Sta Helena©, SX5885 VIP3 Syngenta©, SX71715 VIP3 Syngenta© and SX8934 VIP3 Syngenta© that were grown in the municipality of Ipameri, GO. Analyzed the percentage of primary root emission (ERP),% of shoot emission (EPA),% of microorganism incidence, % of fungus genera (% GF). Sixteen fungi were detected representing the microflora detected in the seeds of the evaluated hybrids recognized as Penicillium sp., Aspergillus sp., Curvularia sp., Fusarium verticillioides, Gliomastix sp., Cladosporium sp., Gliocladium sp., Bacillus sp., Geotrichum sp. , Trichoderma sp., Mucor sp., Stenocarpela maydis, Pythium sp., Chaetomium sp., Sporotrix sp. and Scopulariopsis sp. The multivariate analysis jointed the cultivars with highest physiological activity represented by SX 8934 Vip3 SYN®, SX 71715 Vip 3®, 3040 Vip3 LG®, SHS 7990 PRO2, SX 5885 Vip3, MG 652 PW®, K9606 Vip3®, DKB 345 PRO3. The lowest incidence of microorganism was in hybrids DKB 345 PRO3 and 8882 cod.

“…These processes are directly related to rapid and uniform soil cover, to fast gain in dry matter, and, consequently, higher yield, significantly contributing to gains in seed production (Canedo et al, 2013). In a study performed by Danelli et al (2011) evaluating the quality of soybean seeds as affected by foliar treatment in the field, the authors found that the effect of the fungicides applied on the aboveground part of soybean favored seed physiological quality, and the best fungicides were those with the active ingredients pyraclostrobin + epoxiconazole and trifloxystrobin + cyproconazole. Nevertheless, Gagliardi et al ( 2009), Pinto et al (2011), andBrzezinski et al (2012) did not observe an effect of foliar fungicides on the physiological quality of soybean seeds.…”

Controlling disease in the soybean crop is essential for obtaining high quality seeds and high yield. This leads the producer to increase the number of fungicide applications as a preventive measure. The aim of this study was to evaluate soybean response to increase in the number of foliar applications of different chemical fungicides during crop development to enhance the physiological and sanitary quality of soybean seeds. The experiment was performed in the state of Minas Gerais, Brazil, in two environments (Ijaci and Lavras) in the 2014/15 crop year, with the cultivar BRSMG 850G RR . The field experiment was conducted in randomized blocks in split-plots, with three replications. The plots were composed of the number of applications (0, 1, 2, 3, 4 and 5 times). The applications started at the R 1 stage (beginning of bloom), with a 15-day interval to the next application (R 1 ; R 1 +15d; R 1 +30d; R 1 +45d; R 1 +60d). The split-plots were constituted by the different chemical fungicides (Elatus ® , Fox ® , Opera ® , Orkestra ®, and an unregistered product -BAS -702). Seeds were evaluated soon after harvest and after eight months of storage. The following characteristics were evaluated: seed water content, germination in paper and sand substrates, emergence, emergence speed index, mechanical damage in the sodium hypochlorite test, electrical conductivity, accelerated aging, seed vigor and viability by the tetrazolium test, and seed health, using a completely randomized design. Regardless of which fungicide was used, an increase in the number of foliar applications of fungicides, up to five applications, leads to an increase in the physiological and sanitary quality of soybean seeds, both those newly harvested and those stored for eight months. However, Fox ® fungicide (trifloxystrobin + prothioconazole) applied on the leaf during the reproductive stages of the soybean crop brought about the best results in the physiological quality of newly harvested seeds and seeds stored for eight months, as well as in the sanitary quality of newly harvested seeds.
