HELIOS Marine-sourced bioactive compounds to prevent growth of Orobanche among crops
The HELIOS project aimed to develop an effective solution to eradicating Orobanche (Broomrape), a genus of parasitic plants which attack numerous cultivated crops.
The R&D carried out during the project has led to the discovery of extracts from marine algae and halophytes which impact on how the parasite and host interact. Research has mainly focused on treatments prior to colonisation of the host and thus to the emergence of the parasite. The aim of this innovative approach was to divert the attention of the parasite away from the host plant and even to repel it. Controlled field trials evaluated how effective these new marine-sourced bioactive compounds actually were to determine the most efficient application methods and to guarantee optimum yields for the target crops.
The HELIOS project results are promising and will lead to development of a new, marine-sourced environmentally friendly solution as an alternative to genetic selection and herbicide-tolerant varieties of crops.
