Development of Pseudomonas Culture Extract to REduce Septoria tritici blotch – CERES

Biocontrol products, plant protection products based of living organisms or natural substances, constitute a pathway promising to reduce the use of plant protection products. However, there are still few solutions for diseases field crops.
The maturation project proposes to develop new products of biocontrol based on lipopeptides from bacterial cultures Pseudomonas to control the main fungal disease of wheat: the Septoria tritici blotch. It is based on the results of the LIPOCONTROLE project ECOPHYTO PSPE 2 - 2014: “Contributing to the growth of biocontrol” that provide the experimental proof of design (TRL 3) that the Pseudomonas culture extracts containing lipopeptides reduce effectively the disease.
The objective of the project is to demonstrate at a field level that lipopeptides extracts from culture of Pseudomonas bacteria constitutes a functional biocontrol solution against Septoria tritici blotch (TRL 5). For achieve this goal, the work program is to design and develop the lipopeptide extract production process up to the pilot scale, to assess the level of toxicity, ecotoxicity and stability of extracts efficiency, to define their use conditions in the greenhouse, to test their effectiveness in the field and to define the strategy for the best dissemination of the solution to wheat producers.
