“…The results of forest seed health obtained in research developed with seed treatment, involving physical methods (Oliveira et al, 2011;Lazarotto et al, 2013;Françoso and Barbedo, 2014;Hennipman et al, 2017), biological methods (Fantinel et al, 2015;Martín-García et al, 2017;Silva et al, 2018) and more recently the use of plant extracts (Choudhury et al, 2018;Dourado et al, 2020;Lima et al, 2020;Almeida et al, 2021;Andrade et al, 2021), have shown some advances in pathogen control. However, studies that seek to increase the storage period, especially of species intolerant to desiccation, despite important advances, have not yet achieved substantial gains, obtaining an extension for a few months or, exceptionally, years (Barbedo, 2018).…”

Seed pathology is an area of study that began in the last century and has been developing since then, with increasing contribution especially to agricultural production systems. However, in the environmental area, studies began much later, but showed equal importance, especially for plant restoration and germplasm conservation programs. In this review, information about the knowledge on the pathology of seeds of non-domesticated species from tropical ecosystems is presented and the benefits and gaps of these studies are discussed.

“…Essa espécie bacteriana também tem sido empregada no controle de doenças de plantas, devido a produção de antibióticos como a zwittermicin A, e lactonas Nacil-homoserina (AHC) que são moléculas sinalizadores envolvidas na detecção do quorum sensing bacteriano (Silo-Suh et al, 1994;Dong et al, 2002).

“…A termoterapia é um método de controle físico que se baseia na exposição das sementes ao calor úmido ou seco, em que o período de exposição ao calor é capaz de controlar os fitopatógenos sem prejudicar a qualidade fisiológica das sementes (Françoso & Barbedo, 2014). Além desse método, a aplicação de microrganismos vivos às sementes, como espécies de bactérias do gênero Bacillus, também tem se mostrado uma alternativa promissora no controle de patógenos, atuam por meio de diferentes mecanismos de ação, como antibiose, competição e liberação de compostos voláteis (Dourado et al, 2020), bem como promotores de crescimento da planta (Diniz et al, 2009). Com isso, tanto a termoterapia quanto o controle biológico tem produzido resultados positivos no controle de fitopatógenos transmitidos por sementes de hortaliças (Costa et al, 2021;Cunha et al, 2017;Dourado et al, 2020;Pedroso et al, 2018).…”

The objective of this study was to assess seed health and the effect of plant extracts on Fusarium oxysporum f. sp.vasinfectum mycelial growth and sporulation, plant pathogen reduction in seeds and fusariosis control in okra seedlings.Health was assessed by the Blotter Test, after immersing the seeds in natural extracts and plating. To verify the mycelial growth of the plant pathogen, the extracts were incorporated in PDA culture medium and the pathogen was added and assessed, including the spore count. In the greenhouse, the seeds were immersed in the extracts, sown and at 15 days they were sprayed with extracts, at 21 days inoculated with the pathogen and disease severity on the seedlings was assessed 7 days later. There were higher incidences of Fusarium sp. and Rhizopus stolonifer in the seeds of the cultivars Valença and Santa Cruz 47. The extracts that resulted in lower pathogen incidence was basil, in cv. Valença and cinnamon and neem, in cv. Santa Cruz 47. The neem treatment presented the best inhibition percentage and the lowest sporulation mean in mycelial growth of the pathogen. Neem presented higher disease incidence control in the seedlings of cv. Valença and basil on the seedlings of cv. Santa Cruz 47.
