Previous projects (BIOINPUT-CGL2016-78660-R, BIOLLETS-PID2019-111253RB-I00) led to the invention of a pre-emergence ecoherbicide based on mixtures of densified allelopathic biomass suitable for integrated weed management (IWM). In BIOLLETS, a formulation's phytotoxic effects and performance control a selection of weeds in a single soil and cropping system. This community is intended to gather all research results of the projects involved in BIOLLETS.
