What if it doesn't work? An example for a promising biological control agent that negatively influence the plant instead of helping it
Abstract: Plants were inoculated with the endophytic Penicillium sp. and then appeared to beover sensitive to phytopathogens, which is quite original in terms of biocontrol. In this case theinoculated plants displayed stronger symptoms than the control. On the other hand an extractionof the growth medium was found to be active and provided protection to plants againstpathogens. It is likely that the benefit coming from the described endophyte will not be due tointroduction of the endophyte into the plant rather using its secondary metabolites as “naturalpesticides”.
