Weed control is a critical factor to ensure productivity and quality for food production. Chemical control is the main method used worldwide, but the demand for healthier food and the farmers' health and environment concerns have led to an increase in the search for alternative control methods. In this way, the use of biomolecules produced by microorganisms that present phytotoxic activity against weeds, such as exopolysaccharides, is attracting attention.

Fungi are considered the most damaging microorganisms in agriculture. The indiscriminate use of chemical treatments in agricultural products causes the development of pest resistance and affects human health. An alternative to synthetic fungicides is the use of natural products such as plant extracts for the management of fungal diseases in plants.

Article Synopsis
  • The study aimed to develop an herbicide using submerged fermentation in a bioreactor while investigating its effects on cucumber and sorghum species at various growth stages.
  • The fermentation process involved varying the stirring rates and aeration levels to optimize bioherbicide production, with analysis of the byproducts through gas chromatography.
  • Results showed a complete inhibition of seed germination and variable phytotoxic effects on both plant species, indicating the potential of the metabolites as a future option for controlling weeds.
