“…Esse fungo pode produzir compostos tóxicos chamados aflatoxinas, que possuem efeitos carcinogênicos (Hosseini et al, 2020). Quando possui alta incidência, pode reduzir o poder germinativo da semente e a emergência das plântulas.…”

“…Em função disso, medidas alternativas de controle têm sido buscadas como a utilização de quitosana (Katiyar et al, 2015), Bacillus subtilis (Lanna Filho et al, 2010), enxofre (De Souza et al, 2017) e hipoclorito de sódio (Walter et al, 2009). No entanto, existem poucas informações sobre a interferência na qualidade fisiológica e sanitária de sementes de soja, cujas plantas foram submetidas a tratamentos alternativos para o controle de doenças foliares.…”

Para avaliar a germinação e sanidade de sementes em função da aplicação foliar de produtos alternativos isolados e associados a fungicida na cultura da soja, foram utilizadas amostras de sementes coletadas em 2016/2017 e 2017/2018, das cultivares NA5909 e TMG7062, semeadas em outubro e dezembro. Os tratamentos foram constituídos da aplicação foliar de produtos à campo, com Bacillus subtilis, quitosana, enxofre e hipoclorito de sódio, isolados ou associados ao fungicida e o fungicida isolado aplicado duas e três vezes. A germinação da NA5909 não apresentou diferença estatística entre os tratamentos, nas duas épocas de semeadura, nas duas safras. Na TMG7062, os tratamentos com B. subtilis, quitosana, e enxofre, isolados e associados ao fungicida, e o fungicida isolado diferiram da testemunha apenas na primeira época de semeadura. NA5909 apresentou maiores valores de germinação que TMG7062. Os produtos alternativos testados não apresentaram efeitos fitotóxicos à germinação das cultivares. Na segunda época de semeadura houve menor incidência de patógenos nas sementes e maior germinação nas duas cultivares. O fungicida isolado, B. subitilis e enxofre isolados e associados ao fungicida reduziram a incidência dos patógenos nas das cultivares. Não houve diferença para a germinação e sanidade com duas ou três aplicações do fungicida.

Aflatoxins (AFs) are highly toxic and cancer-causing compounds, predominantly synthesized by the Aspergillus species. AFs biosynthesis is a lengthy process that requires as minimum as 30 genes grouped inside 75 kilobytes (kB) of gene clusters, which are regulated by specific transcription factors, including aflR, aflS, and some general transcription factors. This paper summarizes the status of research on characterizing structural and regulatory genes associated with AF production and their roles in aflatoxigenic fungi, particularly Aspergillus flavus and A. parasiticus, and enhances the current understanding of AFs that adversely affect humans and animals with a great emphasis on toxicity and preventive methods.

“…It is believed that certain types of social immunity behavior, such as the collection of plant resins and their deposition in the nest as an antimicrobial propolis envelope, have evolved to compensate for deficiencies in innate or physiological immunity [112]. These facts have been supported by evidence that propolis may reduce the effects of mycotoxins produced by fungi [113]. There are multiple honey bee products, such as nectar and pollen, that contribute to social immunity and have a direct influence on colony health [114].…”

Wild and managed bees provide pollination services to crops and wild plants, as well as a variety of other services beneficial to humans. Honey bees are the most economically valuable pollinator worldwide. It has been calculated that 9.5% of the total economic value of agricultural production comes from insect pollination, thus amounting to just under USD 200 billion globally. More than 100 important crops depend on pollination by honey bees. The latter pollinate not only a wide number of commercial crops but also many wild plants, some of which are threatened by extinction and constitute a valuable genetic resource. Moreover, as pollinators, honey bees play a significant role in every aspect of the ecosystem by facilitating the growth of trees, flowers, and other plants that serve as food and shelter for many large and small creatures. In this paper, we describe how the reduction in honey bee populations affects various economic sectors, as well as human health.
