Harnessing Streptomyces for sustainable bocontrol in agriculture: The discovery of Streptomyces sp. GanoSA1

Abstract: Phytopathogens significantly threaten global agriculture, causing devastating losses
in crop yield and quality. These plant pathogens, including fungi, bacteria, viruses, and
nematodes, can trigger diseases that weaken plant health, reduce productivity, and threaten food security. The economic impact is immense, as farmers suffer financial losses due to reduced harvests and increased costs for disease management. Moreover, phytopathogen outbreaks can disrupt supply chains and increase food prices. Climate change and global trade further exacerbate the spread of these pathogens, necessitating sustainable disease management strategies such as biocontrol, resistant crop varieties, and integrated pest management, enhanced the growth of oil palm seedlings and reduced the effect and severity of BSR on test seedlings, suggesting that it may have the potential to be used as a biopesticide. This paper describes the discovery of Streptomyces GanoSA1 from in vitro, greenhouse and field, proving its potential for biocontrol activity that is environmentally friendly and sustainable.
