Biocontrol of weeds toxic to human and animal health

imson weed (Datura stramonium L.) is an invasive weed plant that produces alkaloids that are particularly toxic to humans (crop contamination) and animals (fodder). The objective of my research project is to find a biocontrol solution based on the use of fungi (even oomycetes) and/or plant extracts to control this plant in agricultural plots. At first, I focus on the research of mycoherbicides. The presence of pathogens or phytotoxic metabolites for jimson weed in a panel of non-infested soils to highly infested soils is tested by applying aqueous extracts or filtrates (0.2µm) of these soil extracts to datura seeds placed on germination paper under controlled temperature and humidity condit…
