Biocontrol products and biostimulants :
which added-value for specialized plant production?
Overview of the biocontrol and biostimulants markets,
on-field implementations and upcoming developments.

Tuesday, January 15th from 14:30 to 17:30 (SIVAL) - ANGERS



Agriculture is now facing a complex issue: how can it produce as much, if not more, but better, by reducing the use of traditional inputs? To answer this question, it is urgent to deploy and find new solutions; here, the biocontrol products and biostimulants have high potential to offer alternative solutions in response to this issue.


These products, with their modes of action different from the traditional products, are often still unknown. Their appropriation/use by the producers remains to be developed and has to be supported in order to optimize the added value these products give to the specialized production systems.

Thus, the “Végépolys Symposium 2019” intends to provide an answer to the following question: Which added value for specialized plant can be brought by biocontrol and biostimulant products?


The Main objectives are to:

  • the existing differences between biostimulants and biocontrol products,
  • present the existing solutions,
  • present the promising research and development results,
  • deliver some take-home messages for an efficient use of these products (scientific information about conditions required: plant ecophysiology, pedo-climatic conditions
  • By keeping a good balance between usefull information for farmers (more technical) and high level scientific information.

Presentation of promising research and development projects (France and Europe)

Jürgen Köhl, Wageningen University & Research

Senior Scientist at Wageningen University & ResearchJürgen Köhl
Plant Pathology | Biological control | Epidemiology

He focuses his research on sustainable solutions ensuring plant health. The main topics are the biological control of fungal plant pathogens using antagonistic fungi and methods for disease prevention. Understanding disease epidemiology often is a first step in such studies. During the last years, he worked on the disease management in pome fruits, cereals and vegetables with emphasis on leaf and fruit diseases.


orchard.Jürgen KöhlAbstract: Development of new biocontrol products: Joint efforts of science and industry

Commercial biological control products for the use against plant diseases must be highly efficient against the targeted diseases. However, the used antagonists have to fulfil a broad range of requirements besides their ability to control pathogens such as suitable ecological characteristics, low risks for users, consumers and environment, and feasible production costs. Thus, new biocontrol products can only be developed in joint collaborations of science institutes and biocontrol industries combining different expertise’s from plant pathology  to biotechnology and marketing.

SENSOR.MESURE(D.WERBROUCK)Abstract:  European project Bio4Safe : An innovative approach to evaluate biostimulant and new piloting means.

The target : reduce respectively of 20% and 10% the water and fertilizers consumption by used biostimulants, have news sensors to adjust at best the water and fertilizers supplies.

The workpackages  :

  • Achieve a market study on the development of algae production channels.
  • Compare five biostimulants and measure the reaction of plants at fertilization and irrigation change.
  • Build a database and innovative piloting meansto adjust water and fertilizers supplies

Perspectives offered by research results

Matthieu Gaucher - INRA IRHSM.GAUCHER

Research engineer INRA in the research institute in horticulture and seeds (UMR 1345-IRHS). The main research themes are articulated around the use of the stimulating ones of defenses of plants on the apple tree: screening, action mod , molecular tools development, integration in the technical culture routes.



Alternative solutions are urgently needed in order to decrease the use of conventionnal pesticides. Plant Resistance Inducers (PRI) seem to be good candidates for this substitution but their effectiveness in the field is often insufficient, despite encouraging results under controlled conditions. The INRA center of Angers is interested in the use of this category of inputs, mainly in apple growing, with the objectives of i) testing existing products as well as new substances (sourcing) on apple, ii) identifying the factors influencing their efficacy, iii) developing protocols for their integration into pest management programs of the orchard that are lightweight in pesticides, iv) understanding the molecular mechanisms explaining induced resistance and v) developing molecular tools to facilitate their study (screening and mode of action). A state of the art of this work will be presented.

2 - Round table

How to ensure an optimal use of biostimulants and biocontrol products?

  • Success story of one producer (using biocontrol products and biostimulants)
  • His advisor: what are the key steps to support the adoption of these products? Which plan in order to help the transition towards pesticides use reduction?
  • Biocontrol/biostimulant producer:

which support do they offer in order to help the adoption of their products?

What kind of collaboration do they have/need in order to develop new efficient products?

  • Research: key messages to enable ‘stronger’ cropping system emergence

President and creator of company IF TECH (Angers - France) whose the main activity is biostimulants (80%) and the second is the biocontrol (20%). The company proposes alternative solutions to insecticides and chemical fertilisers in different sectors (horticulture, fruit trees, green spaces, vineyard, substrates and durable agriculture) in France and in Europe.

FINANCEMENT PROJET PEIIn charge of the animation of an action dedicated to the identification and the mobilization of alternative practices in order to reduce the use of conventional pesticides in Pays de la Loire.
This study will lead to the elaboration of an overview of current practices and of solutions which are in development, to the identification of the most relevant levers for the regional context and to the construction of an action plan in order to foster their appropriation by farmers.

VEGEPOLYS has been recognised in France as the international plant cluster because of its unique concentration of organisations operating in the plant world. With its 400 members (companies, research centers and training organisations) VEGEPOLYS creates synergies within jointly-run innovative projects. The governement and regional authorities allocate a special budget to collaborative research projects approved by these clusters.
