The present study aimed to evaluate the effect of Bacillus amyloliquefaciens and/or Arbuscular Mycorrhizal Fungi (AMF) as natural biofertilizers on biomass, yield, and seed nutritive quality of soybean (Giza 111). The conditions investigated include a well-watered (WW) control and irrigation withholding at the seed development stage (R5, after 90 days from sowing) (DS). Co-inoculation with B. amyloliquefaciens and AMF, resulted in the highest plant biomass and yield under WW and DS conditions.The nuclear DNA content analysis suggested that co-inoculation with B. amyloliquefaciens and AMF decreased the inhibition of drought stress on both the size and granularity of seed cells, which were comparable to the normal level. The single or co-inoculation with B. amyloliquefaciens and AMF increased the primary metabolites content and alleviated the drought-induced reduction in soluble sugars, lipids, protein and oil contents. Plant inoculation induced the expression of genes involved in lipid and protein biosynthesis, whereas an opposite trend was observed for genes involved in lipid and protein degradation, supporting the observed increase in lipid and protein content. Plant inoculated with B. amyloliquefaciens showed the highest α-amylase and β-amylase activities, indicating improved osmolyte (soluble sugar) synthesis, particularly under drought. Interestingly, single or co-inoculation further strengthen the positive effect of drought on the antioxidant and osmoprotectant levels, i.e. phenol, flavonoid, glycine betaine contents, and glutathione-S-transferase (GST) activity. As a result of stress release, there was a decrease in the level of stress

“…However, there was no difference between type of soils for BV03 bioinoculant. Hence, Rios et al (2018) state that the B. amyloliquefaciens has been showing good results in control nematodes, such as the Meloidogyne incognita (Lobna & Zawam, 2010;Abdel-Salam et al, 2018).…”

Crop yield decrease is the main concern when a pathogen or plague is identified in an agriculture field. Thus, part of this issue can be attributed to plant-parasitic nematodes (PPNs), such as Meloidogyne species, due to, most of the time, the hard diagnosis, and non-specific symptoms. Its management is mainly based on chemical pesticides, followed by a few potential biological control agents, and the management system. Therefore, this study aimed to evaluate the effects of biological agents in Meloidogyne incognita control in different soil systems. For that, two biological products were chosen, Trichoderma asperellum BV10 and Bacillus amyloliquefaciens BV03, and soils were sampled from three different managements systems: (i) soybean no-tilled system at Goiás state, Brazil; (ii) forest soil at Goiás state, Brazil, and (iii) soybean conventional managed system at Mato Grosso do Sul state, Brazil. Biocontrol and growth promotion effects, volatile organic compounds (VOCs) and soil respiration were determined in vegetation house and laboratory, respectively. As a result, both BV10 and BV03 had significant nematode control activity, comparing to control treatment, in all the three soils systems. Plus, the number of immobile nematodes by potential VOCs had significant increase when BV03 was applied, while the application of BV10 agent raised the soil respiration rate. In conclusion, both biocontrol agents presented great efficiency in control M. incognita, with better performance of BV03. Lastly, more studies must be done to elucidate how the resident soil microbiome can influence on biocontrol agent establishment and performance, as well as the consequence of the application of biological products on soil microbiome network.

RESUMO O fungo causador da ferrugem asiática na soja, Phakopsora pachyrhizi, apresenta resistência cruzada e múltipla aos três grupos químicos (triazóis, estrobilurinas e carboxamidas) de fungicidas sítio-específicos. Este fato torna evidente a necessidade da implementação de estratégias para o manejo de prevenção da resistência. Uma alternativa pode ser a utilização de microrganismos com capacidade de interferir no desenvolvimento de patógenos, bem como atuarem como indutores da resistência das plantas. O objetivo do presente trabalho foi avaliar a eficácia de produto biológico à base de Bacillus subtilis BV02 isolado ou associado à produto à base de cobre no controle de ferrugem asiática, bem como desempenho agronômico da soja. Para tanto, foram instalados dois experimentos, sendo um no campo e outro em laboratório. Para o experimento conduzido em campo, o delineamento utilizado foi o de blocos ao acaso, estando os tratamentos dispostos em arranjo fatorial (5x2)+1, com quatro repetições. O primeiro fator correspondeu a aplicação, em pós-emergência da soja, de cinco doses de B. subtilis BV02 (0, 0,5, 1,0, 2,0 ou 4,0 L p.c. ha-1). O segundo fator correspondeu a associação ou não com produto à base de cobre. O tratamento adicional consistiu na aplicação da associação entre os fungicidas [azoxystrobina + benzovindiflupir] + mancozebe. No experimento em laboratório foi avaliada a germinação dos uredósporos de P. pachyrhizi em placas Elisa, no delineamento inteiramente casualizado com oito repetições. Foram utilizados os mesmos tratamentos do experimento do campo, diferenciando-se apenas o fungicida químico, o qual não foi adicionado mancozebe a calda aplicada. O aumento de dose de B. subtilis BV02, aplicado isoladamente, proporcionou reduções na severidade de ferrugem, não sendo visualizado este comportamento quando associado ao produto à base de cobre. Para a associação entre B. subtilis BV02 e produto à base de cobre, os melhores resultados para o controle de ferrugem asiática foram visualizados em doses iguais ou inferiores a 1,0 L p.c. ha-1. A produtividade da soja foi superior ao tratamento contendo fungicidas com a utilização de B. subtilis BV02 isolado (1,0 e 2,0 L p.c. ha-1), com aplicação apenas de produto à base de cobre e com utilização deste micronutriente em associação ao B. subtilis BV02 (2,0 L p.c. ha-1).
