Encapsulation of bacterial-fungal consortia for agricultural applications

Abstract

Each year, fungal pathogens cause 13% of agricultural losses. Soil-borne fungi are difficult to control because they can infect multiple plant species and survive without a host for more than 10 years. Synthetic fungicides are the most effective means of control, but they have drawbacks such as the development of resistance and harmful effects on ecosystems and human health. In addition, there is a growing demand for pesticide-free food. There is therefore an urgent need to develop alternative control methods. A number of biofungicides are on the market, but their efficacy is inferior to that of synthetic fungicides. In the soil, they compete with other microbes, limiting their growth, spread and activity.  
 
The aim of this project is to develop a new type of biofungicide by combining several microorganisms, fungi and bacteria, in the form of microcapsules, in active forms and acting synergistically. To achieve this, the project has five objectives:

  • to isolate and select effective bacterial-fungal combinations for a given pathosystem
  • to ensure the environmental safety of these new biofungicides through in-depth genetic testing
  • to use microfluidics to create an effective formulation in microcapsule form and develop a manufacturing process aimed at industrial production
  • to test this new formulation under real-life conditions
  • and to work directly with farmers to meet their needs.  

This project aims to offer an ecological alternative to synthetic fungicides, anticipating future restrictions on pesticides and providing new solutions for sustainable agriculture.
