Improving the efficiency and use of biocontrol products

The french “Consortium Biocontrôle” is funding projects of interest to the sector, focused on technologies and know-how in the use of biocontrol products.

The consortium biocontôle brings together public and private sector actors in research on biocontrol products. It entered its operational phase in 2016, and funded since then 3 research projects of importance to the sector. Two of them were launched in 2018, the projects CARE and BCMicrobiome.

Determining the physiological status of plants

A plant affected by biotic and/or abiotic stress is potentially less receptive to the solutions applied, so that its status influences the efficiency of the products employed.
It is therefore important to be able to characterise the physiological status of plants.  
The CARE project (characterising the stress status of plants using transposable elements) is designed to determine whether it is possible to measure the physiological status of plants.
The project aims to prove that the activation of transposable elements could be used as a marker of stress. Transposable elements are so-called "mobile" DNA sequences which make up a large proportion of the genome of eukaryotes and are able to move from one site on a chromosome to another.
If validated, this hypothesis  would allow the development of tools to evaluate the physiological status of plants during and after the use of biocontrol products. These tools could then be used by Consortium members to determine factors for the successful use of biocontrol products, with a view to developing know-how on their efficacy and clarifying their market positioning.

Reconstructing microbial networks

Our increasing knowledge of the phytobiome1 offers opportunities to improve the use of biocontrol products. Indeed, plants are associated with a wide variety of interacting micro-organisms. These microbial interactions contribute to regulating diseases so it is crucial to be able to identify them, which is generally achieved through co-culture experiments. However, this work is lengthy and complicated and cannot be applied to the entire microbial community with which the pathogen interacts. A current challenge is therefore to reconstruct networks of microbial interactions based on meta-barcoding data.
The BCMicrobiome project aims to develop a method to reconstruct the network of interactions between a pathogen and the microbiome of a plant. By studying two major pathogens that attack the leaves of vines (Plasmopara viticola, the causal agent of mildew) and wheat (Zymoseptoria tritici, the causal agent of glume blotch), this project will provide members of the consortium with a list of micro-organisms that interact with the target pathogen and are therefore likely to offer opportunities for the development of new biocontrol solutions.
