Communication between plants and Trichoderma spp
Name of the speaker: Professor Maria Isabel Trillas (PhD Biology, Full time lecturer University of Barcelona, co-founder Biocontrol Technologies, finalist EU WomenInnovator Prize 2017)Company: Biocontrol Technologies, S.L.
Topic: 3. Microbials
Summary: Reduction of plant diseasesby Trichoderma spp. goes further than antagonism /competition with pathogens, they also enhance plant resistance. In addition, plants play an active role in the maintenance of the beneficial interaction.
